Description

The present invention relates to a root vegetable harvester that pulls out a crop from a field and removes foliage during transportation to harvest the crop.

The conventional root vegetable harvester transports the crops that have been pulled out from the field and harvested, regulates the upward transport of the crops with a shoulder alignment device, aligns the cutting positions of the foliage, and sandwiches the crops with a pair of left and right rotary blades. There is a technique for dropping and removing the residual leaves remaining on the dropped crop by winding them around a residual leaf processing roller during transportation on a residual leaf processing conveyor. (Patent Document 1) On one of the pair of left and right rotary blades, when the foliage is cut and dropped, a disk made of a soft material is brought into contact with the shoulder of the crop, and the side with the remaining leaves of the crop remains. It is configured to be dropped while facing the leaf treatment roller, and the remaining leaves cannot come into contact with the remaining leaf treatment roller, reducing the occurrence of manual removal of the remaining leaves.

Japanese Unexamined Patent Publication No. 2013-27348

However, in the root vegetable harvester described in Patent Document 1, since the positions where the left and right rotary blades cut the foliage portion are constant, the traveling speed of the machine and the transport speed of crops are increased in order to improve work efficiency. If this is the case, the crop may fall toward the rear of the aircraft instead of directly below due to the inertia when the foliage is cut. As a result, the crop cannot fall on the removal conveyor and is deviated from the conveyor, so that it is necessary to return the crop to the conveyor, which requires extra time and labor.

In addition, depending on the drop position, the crop may be scratched or broken, and the commercial value may be lowered, or the crop may not be commercialized and the yield may be lowered.

In addition, if the position of falling on the residual leaf processing conveyor is closer to the front side of the machine, the chance of contacting the residual leaf removal action range by the residual leaf processing roller (time during which it can be contacted) is reduced, so that residual leaves are left. There is a problem that the crops are transported as they are, and it becomes necessary to manually remove the residual leaves.

In addition, since the transport speed by the pull-out transport device and the residual leaf processing conveyor is linked to the traveling speed, the preceding crop is used when harvesting crops at the above-mentioned high speed or when the distance between crops is narrow, so-called stock spacing. May fall onto the residual leaf processing conveyor and move from the spot to allow subsequent crops to fall before the fall space opens, causing the crops to collide and be damaged, reducing commercial value and yield. There is a problem of doing.

In addition, the preceding crop from which the residual leaves have been removed by the residual leaf treatment roller prevents the subsequent crops from approaching the residual leaf treatment roller, and the crop is transported with the residual leaves left, which is manually performed. There is a problem that it becomes necessary to perform the work of removing the residual leaves.

When the tension plate 52L of the device 53L is provided on the rear side of the machine body with respect to the tension plate 52R of the alignment device 53R, the tension plate 52L or the tension when the large-diameter foliage h passes between the left and right sides of the alignment devices 54L and 54R. Since the alignment chain 48 and the alignment guide body 52 move to the side without the plate 52R, even if the diameter of the foliage h of the carrot is large, it can be prevented from being bitten by the alignment devices 54L and 54R, and the machine is stopped. It is not necessary to remove the foliage h that has been bitten by the carrot, and the work efficiency is improved.

In addition, if the tension of the tension plates 53L and 53R is set to be weaker than the tension of the urging springs 50 and 50, the alignment chains 48 and 48 are appropriate when a large-diameter foliage h passes and a load is applied. It can be bent to a position and retracted, can be prevented from being bitten by 54L and 54R, and it is not necessary to stop the machine body to remove the bitten foliage portion h, which improves work efficiency.

Then, an elongated hole is formed in the transmission cases 37, 37 in the vicinity of the alignment drive sprocket 42, 42 and at an outer position of the alignment guide bodies 52, 52, and the surface of the alignment guide bodies 52, 52 is formed in the elongated hole. The left and right scrapers 55, 55 for removing scraps, mud, etc. of the foliage portion h adhering to the alignment guide body 52, 52 are attached at the time of position adjustment along the trajectory of the alignment guide bodies 52, 52.

By arranging the scrapers 55 and 55 in a backward tilted posture, it becomes easy to drop a piece of the foliage portion h and mud downward.

Then, the left and right cutting blade rotation shafts 56 and 56 are provided at the rear positions of the shoulder alignment devices 54L and 54R of the left and right first gear units 38 and 38, and the left and right bearings 57 and 57 are attached to the cutting blade rotation shafts 56 and 56. It attaches freely. Then, the left and right support plates 59 and 59 are attached to the left and right bearings 57 and 57, and the left and right foliage cutting blades 60L and 60R are attached to the support plates 59 and 59 to form the foliage cutting device 61.

The left and right foliage cutting blades 60L and 60R are circular rotary blades, and the blade edges of the left and right shoulder aligning devices 54L and 54R overlap each other in the vicinity of the left and right center portions, so that the carrot foliage portion h is formed. It is sandwiched and cut to drop carrots. Since the carrot harvester of this example has a configuration in which the cutting heights are aligned by contacting the bottoms of the left and right shoulder aligning devices 54L and 54R, the left and right foliage cutting blades 60L and 60R are larger than the hairline of the carrot foliage h. The foliage h is cut on the upper side.

Therefore, in the carrot that is cut off from the foliage portion h and falls, the foliage portion h is left uncut, so-called residual leaf hr. This residual leaf hr needs to be removed before shipping, and after the harvesting work, the operator needs to manually remove it using a kitchen knife or the like. However, the residual leaf processing section E, which will be described later, is placed below the foliage cutting section D. By providing the structure, the residual leaf hr can be automatically removed during the harvesting operation.

However, depending on the position where the carrot falls to the residual leaf processing unit E, there is not enough opportunity to come into contact with the residual leaf processing action position when the carrot is transported by the residual leaf processing unit E, and the residual leaf hr remains. It is sent from the residual leaf processing unit E to the post-process, and it becomes necessary for the worker to manually remove the residual leaf hr after harvesting, which requires extra labor and extra time for shipping preparation. There is a problem that needs to be done.

In order to solve this problem, as shown in FIGS. 14A and 14B, of the left and right foliage cutting blades 60L and 60R constituting the foliage cutting device 61, the outside of the machine body (one side on the left and right sides of the machine body) The position of the left foliage cutting blade 60L to be provided shall be fixed. Then, the front end portion of the cutting transmission case 600 that transmits the driving force is quickly attached to the rear upper portion of the left shoulder alignment device 54L, and the left foliage cutting blade 60L is attached to the rear lower portion of the cutting transmission case 600. To do.

Inside the cutting transmission case 600, a driving sprocket 601 that receives a driving force from the left shoulder alignment device 54L, a driven sprocket 602 that rotates the left foliage cutting blade 60L, and the driving sprocket 601 and the driven sprocket 602. A transmission chain 603 that is wound and transmits a driving force is arranged.

On the other hand, the right foliage cutting blade 60R provided on the inside of the machine body (on the left and right sides of the machine body) can adjust the position of the left foliage cutting blade 60L in the front-rear direction of the machine body to change the cutting timing of the foliage portion h. It is mounted via the device 604. The front-back adjustment range of the right foliage cutting blade 60R is such that the left foliage cutting blade 60L and the front end are aligned in the left-right direction when moved to the front, and the left foliage cutting blade 60L even when moved to the rearmost position. Is a range that partially overlaps in plan view.

The base of the fixed-side transmission case 605 in a posture of facing the rear side of the aircraft from the rear upper part of the right shoulder alignment device 54R is provided, and the end portion is provided on the upper part of the fixed-side transmission case 605 on the end side. A rotating side transmission case 609 whose side faces the outside of the machine body is rotatably attached. A right foliage cutting blade 60R is attached to the lower portion of the rotating side transmission case 609 on the end side.

Inside the fixed side transmission case 605, there are a fixed side input sprocket 606 that receives a driving force from the shoulder alignment device 54R on the right side, a fixed side output sprocket 607 that outputs the driving force, and the fixed side input sprocket 606 and the fixed side. A fixed-side transmission chain 608 that is wound around the output sprocket 607 and transmits a driving force is arranged.

Further, inside the rotation side transmission case 609, a rotation side input sprocket 610 that receives a driving force from the fixed side transmission case 605, a rotation side output sprocket 611 that rotates the right foliage cutting blade 60R, and the same. A rotating side transmission chain 612, which is wound around the rotating side input sprocket 610 and the rotating side output sprocket 611 and transmits a driving force, is arranged.

A rack gear 613 that determines the rotation range of the rotation side transmission case 609 is provided outside the rotation side transmission case 609, and a rotation motor 615 having a pinion gear 614 that meshes with the rack gear 613 is provided. It constitutes a mobile device 604. The rotation motor 615 is a forward / reverse motor.

The outer side of the machine, that is, the left foliage cutting blade 60L may be provided with a device having the same configuration as the moving device 604 so that the front-rear position can be adjusted, but if the position of either the left or right cutting blade is changed, Since the timing at which the foliage portion h is cut is changed, in the example of the present application, only the foliage cutting blade 60R on the inside (right side) of the machine body is configured to be adjustable in the front-rear position in order to suppress an increase in the number of parts and costs.

Further, since a dustproof cover is provided on the outside of the body of the pull-out transport device 24 to prevent impurities such as soil and leaf debris from scattering, it is difficult to adjust the front-rear position of the foliage cutting blade 60L by the moving device 604. is there. Therefore, in this example, only the foliage cutting blade 60R on the inside (right side) of the machine body is configured so that the front-back position can be adjusted.

With the above configuration, when the moving device 604 is operated to move the right foliage cutting blade 60R backward, the left and right foliage cutting blades 60L and 60R overlap and the cutting action position for cutting the foliage h is moved toward the rear side of the machine body. Can be changed.

By setting the cutting position of the foliage h to the rear of the machine when harvesting carrots at low speed, the carrots that are cut and fall from the foliage h are placed near the rear end of the machine of the residual leaf processing unit E, which will be described later. That is, since it can be dropped near the residual leaf treatment start end portion of the residual leaf treatment roller 75, the residual leaf hr can be removed by using substantially the entire width of the residual leaf treatment roller 75 in the front-rear direction. Therefore, it is possible to reduce the time and labor required for the work of removing the residual leaf hr from the carrot after harvesting.

In addition, during high-speed work, the front and rear positions of the left and right foliage cutting blades 60L and 60R are aligned, the cutting action position of the foliage portion h is closer to the front side of the machine body, and the carrots fall faster, so that the front and rear of the residual leaf processing portion E The width can be used to receive the falling carrots.

As a result, the fallen carrots are scattered in the front-rear direction and transported toward the left and right sides of the aircraft, so it is easy to prevent the carrots that precede the falling position of the following carrots, and the carrots collide with each other and are damaged. It prevents the commercial value from deteriorating.

Further, since the fixed side transmission case 605 and the rotation side transmission case 609 constituting the moving device 604 are arranged so as to avoid the transport paths of the pull-out transport device 24 and the shoulder alignment devices 54L and 54R, they interfere with the transport of carrots. It prevents the carrots from being damaged by contact and the commercial value from being reduced.

Further, since the end side of the rotation side transmission case 609 is configured to rotate so as to swing back and forth, the foliage cutting blade on the left side of the machine is within the range in which the front and rear position of the foliage cutting blade 60R on the right side of the machine can be adjusted. Since it is possible to suppress an increase or decrease in the overlapping area between the 60L and the foliage cutting blade 60R on the right side of the machine body, the foliage portion h can be reliably cut.

Further, the left and right first output shafts 40 and 40 are provided with left and right foliage transport drive pulleys 62 and 62, and the left and right foliage transports are provided on the front side of the machine body and above the shoulder alignment devices 54L and 54R than the left and right first gear units 38 and 38. The driven pulleys 63 and 63 are rotatably attached. Then, by winding the left and right foliage transport belts 64 and 64 around the left and right foliage transport drive pulleys 62 and 62 and the left and right foliage transport driven pulleys 63 and 63 in an endless manner, the carrot foliage portion is wound from the pull-out transport device 24. The leaf-removing transfer device 65 that takes over h and discharges it to the rear of the machine body is configured on the upper outer periphery of the left and right transmission cases 37, 37 and below the transfer end side of the pull-out transfer device 24.

Further, left and right residual leaf transport drive pulleys 66, 66 are provided at the upper ends of the left and right first output shafts 40, 40, and left and right residual leaf transport driven pulleys 67, 67 are provided above the left and right transmission cases 37, 37. Is rotatably attached, and a plurality of left and right residual leaf transport tension pulleys 68, 68 ... Are attached between the left and right residual leaf transport drive pulleys 66, 66 and the left and right residual leaf transport driven pulleys 67, 67. Then, the left and right residual leaf transport drive pulleys 66, 66, the left and right residual leaf transport driven pulleys 67, 67, the left and right residual leaf transport tension pulleys 68, 68, and the left and right residual leaf transport belts 69, 69 are endless. The residual leaf transport device 70 that sandwiches the upper part of the foliage and transports it to the rear of the machine body by winding is configured above the leaf removal transport device 65.

A leaf-removing shooter 71 for discharging the foliage cut by the foliage cutting device 61 from the terminal portions of the leaf-removing transport device 65 and the residual leaf-transporting device 70 to the field is provided to form the foliage-cutting portion D.

With the above configuration, the left and right alignment drive sprockets 42, 42 are arranged at positions separated from the left and right spacing portions of the shoulder alignment devices 54L, 54R through which the foliage portion h passes, so that the alignment drive sprockets 42, 42 and Since it is possible to prevent the foliage portion h from being entangled with the second output shafts 41 and 41 and stopping the shoulder alignment devices 54L and 54R, the harvesting work is not interrupted and the work efficiency is improved.

Further, by making the alignment drive sprockets 42, 42 smaller in diameter than the alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47, the alignment drive sprockets 42, 42 are further left and right of the shoulder alignment devices 54L, 54R. Since it is separated from the interval portion, it is possible to further prevent the foliage portion h from being entangled with the alignment drive sprockets 42, 42 and the second output shafts 41, 41, and the work efficiency is further improved.

By providing the left and right urging springs 50 and 50 for urging the alignment driven sprockets 45 and 45, the left and right alignment chains 48 and 48 when the foliage h comes into contact with the shoulder alignment devices 54L and 54R. Since the alignment chains 48 and 48 immediately return to the tensioned state, the shoulder alignment devices 54L and 54R can reliably pass the sprocket h of different diameters even when the sprocket parts h of different diameters pass continuously. The foliage h can be received, the cutting positions of the foliage h of the carrot are properly aligned, the foliage h is cut properly, and it is not necessary to remove the foliage h in a subsequent step, which improves work efficiency. ..

In addition, the tension of the urging springs 50 and 50 is adjusted by moving the left and right receiving plates 49 and 49 in the front-rear direction, so that the diameter of the foliage h differs depending on the growing condition of the carrot and the variety, or the weather. Since the tension can be changed appropriately according to the work conditions of the work place such as soil quality, the foliage part that remains in the carrot in the post-process by properly aligning the foliage cutting position of the carrot and surely cutting the foliage part h. It is not necessary to remove h, and work efficiency is improved.

Further, the left and right alignment frames 43, 43 are formed with holes 44, 44 in the left-right direction of the machine body, and the rotation shafts 46, 46 provided with the alignment driven sprockets 45, 45 in the holes 44, 44 can be moved freely. Since the alignment driven sprockets 45 and 45 urged by the urging springs 50 and 50 move closer to the transport path of the foliage h, the small-diameter foliage h passes through when no load is applied. At this time, the shoulder alignment devices 54L and 54R receive the foliage h and can properly align the cutting position of the foliage h of the carrot, eliminating the need to remove the foliage h remaining on the carrot in the subsequent process, improving work efficiency. To do.

Further, when a large load is applied to the left and right shoulder aligning devices 54L and 54R when the large-diameter foliage portion h passes, the alignment driven sprockets 45 and 45 move the foliage portion h along the holes 44 and 44. Since it moves in the direction away from the shoulder alignment device 54L, 54R, the left-right spacing on the front side of the shoulder alignment device 54L, 54R becomes wider, and it is possible to prevent the foliage h from being bitten by the spacing portion of the shoulder alignment device 54L, 54R, and the aircraft is stopped. It is not necessary to remove the bitten foliage h, which improves work efficiency.

If it is known before the harvesting work that the foliage h of the carrot has a large diameter, the alignment driven sprockets 45 and 45 are separated from the left and right shoulder alignment devices 54L and 54R. By moving and widening the left-right distance on the upper side of the shoulder alignment devices 54L and 54R in the transport direction, it is possible to prevent the shoulder alignment devices 54L and 54R from biting the foliage h, and the bitten foliage h is removed. No work is required and work efficiency is improved.

Then, by attaching the guide cover 51 ... to each of the plurality of links 48a ... constituting the alignment chains 48, 48 to form the alignment guide body 52, the guide cover 51 at an arbitrary position can be freely attached and detached. Even if a part of the guide cover 51 is damaged, the proper alignment performance is maintained only by replacing the guide cover 51 with a new one, and the foliage portion h is properly cut, so that the work efficiency is improved.

Further, since it is not necessary to replace the entire alignment guide body 52, the cost can be reduced.

Further, since the guide cover 51 can be attached and detached manually without the need for tools, the replacement work can be easily performed.

The guide cover 51 has a U-shape in front view that covers the contact surface between the upper surface and the lower surface of the alignment chain 48 and the foliage h, so that a space portion is formed between the guide cover 51 and the alignment chain 48. Since it does not occur, the foliage h is sandwiched between the guide cover 51 and the alignment chain 48, and it is possible to prevent the carrots from being aligned at the proper cutting position and leaving the foliage h uncut, and the foliage h can be prevented from being left uncut in the subsequent step. The work of removing the part h is not required, the work efficiency is improved, the root of the carrot can be prevented from being cut, and the commercial value of the carrot is improved.

Further, a convex R portion 51a and a concave R portion 51b are formed on the guide cover 51, and the convex R portion 51a of the subsequent guide cover 51 is brought close to the concave R portion 51b of the front guide cover 51. By attaching to the alignment chain 48, when the alignment chain 48 moves around the alignment driven sprocket 45 or the like in an arc orbit, the guide cover 51 ... Can follow and move, so that the shoulder alignment devices 54L and 54R can be used. Since it operates at a constant peripheral speed, it is possible to properly align the cutting position of the foliage h of the carrot by receiving the foliage h, and it is not necessary to remove the foliage h remaining on the carrot in the subsequent process, which improves work efficiency. To do.

Further, by providing the projecting portion 51c protruding upward on the convex R portion 51a, when the alignment chain 48 moves around the alignment driven sprocket 45 or the like in an arc trajectory, the guide covers 51 ... Since the protruding portion 51c covers the space formed between the front and rear, the foliage h is sandwiched between the front and rear spaces of the guide covers 51 ..., and the carrots are not aligned at the proper cutting position and the foliage h is cut. It is possible to prevent the carrot from being left behind, it is not necessary to remove the foliage h in the post-process, the work efficiency is improved, and the root of the carrot can be prevented from being cut, and the commercial value of the carrot is improved.

By providing the left and right tension plates 53L and 53R in the winding area 18i of the alignment chains 48 and 48, the alignment chains 48 and 48 are pressed from the winding area 18i, so that the large-diameter foliage portion h is generated. When passing, the alignment chains 48, 48 of the portion not pressed by the tension plate 53L or the tension plate 53R can be retracted in the direction of the alignment drive sprockets 42, 42, so that the foliage portion h is the shoulder alignment device 54L, 54R. There is no need to be bitten between the left and right sides, and it is not necessary to stop the machine body to remove the bitten foliage h, which improves work efficiency.

Further, by providing the left and right scrapers 55 and 55 for scraping off debris of the foliage h and dirt and other contaminants adhering to the alignment guides 52 and 52 that move around the alignment drive sprockets 42 and 42. Since the impurities adhering to the alignment guide bodies 52 and 52 can be removed at a position away from the movement path of the foliage h, it is possible to prevent debris of the foliage h from getting entangled with each part of the shoulder alignment devices 54L and 54R. Therefore, it is not necessary to stop the aircraft to remove the entangled foliage h debris, which improves work efficiency, prevents mud lumps from damaging the root of ginseng, and improves the commercial value of ginseng.

Furthermore, since the mounting positions of the scrapers 55 and 55 can be changed along the elongated holes, the scrapers 55 and 55 are set at the optimum positions according to the average diameter of the foliage h of the carrot in the field where the harvesting work is performed. However, the above effect is further improved by surely removing the debris of the foliage h and impurities such as mud from the alignment guide body 52 and the office work 52.

Then, the leaf-removing shooter 71, which discharges the leaves (cut foliage h) cut from the carrot by the foliage cutting device 61 to the field, discharges the foliage to the already dug side (the side where the carrot has been harvested). By being provided in a downwardly inclined posture, the discharged foliage falls on the undigged side (the side where the carrot is not harvested), and the discharged leaves are held on the left and right holding transport belts 19, 19 and left and right. Since it is possible to prevent the harvesting section C from being entangled with the driven pulleys 17, 17 and the like to stop the harvesting work and hinder the harvesting work, the work efficiency is improved and the leaves falling on the carrot hinder the visibility of the harvested carrot. Can be prevented.

In addition, in the transmission cases 37, 37, the foliage portion h transported by the residual leaf transport device 70 falls down in the left-right direction of the machine body, and the foliage portion h is not transported to the rear of the machine body. Leaf-removing receiving plates 177 having substantially the same front-rear length as the front-rear direction of the device 70 are provided on the left and right sides, respectively. Due to the presence of the leaf leaf receiving plate 177, when the foliage portion h during transportation is about to fall down, the leaf leaf portion 177 receives the foliage portion h, so that the foliage portion h is transported to the transport end portion by the residual leaf transport device 70. , Is discharged to the field through the leaf-removing shooter 71.

Next, the residual leaf processing unit E will be described.

As shown in FIGS. 1 to 6, front and rear residual leaf processing frames 72 and 72 are provided below the foliage cutting device 61, and the first roller 73a is provided between the front and rear of the residual leaf processing frames 72 and 72 on the left and right sides of the machine body. Is rotatably attached. Further, the second roller 73b is rotatably attached between the front and rear of the left and right sides of the body of the residual leaf processing frames 72 and 72 and below the first residual leaf processing roller 73a.

Then, the residual leaf treatment belt 74 made of an elastic body such as rubber or urethane is wound around the first roller 73a and the second roller 73b in an endless manner. Further, a residual leaf processing roller 75 that sandwiches the residual leaf hr remaining in the carrot together with the residual leaf processing belt 74 and rotates and excises the residual leaf hr remaining on the carrot is attached to the upper part of the residual leaf processing belt 74, and the residual leaf inherited from the foliage cutting portion D. It constitutes a residual leaf processing conveyor 76 that conveys hr from the outside of the machine body to the left and right inside.

Further, a removal transfer motor 620 for rotating the second roller 73 is provided on the rear side of the body of the residual leaf processing conveyor 76 to form a residual leaf processing unit E. The removal transfer motor 620 is a variable rotation motor whose rotation speed can be changed.

The residual leaf processing conveyor 76 is inclined by about 2 to 5 degrees from one side on the left and right sides of the machine to the other side on the left and right sides.

Further, the front end of the residual leaf processing conveyor 76 is located at substantially the same position as the front end of the left and right foliage cutting blades 61L and 61R, or slightly closer to the front of the machine than the front ends of the left and right foliage cutting blades 61L and 61R. The rear end portion is configured to be located on the rear side of the machine body rather than the rear end side of the machine body of the left and right foliage cutting blades 61L and 61R.

As a result, when harvesting work is performed at a high vehicle speed, or when the machine body is liable to shake due to unevenness in the field scene, even if the carrot whose foliage h is cut falls behind the machine body due to inertia, the residual leaf processing conveyor Since the carrot falls within the front-rear width of 76, it is not necessary to return the carrots that have deviated from the transport route to the route, and the work efficiency is improved.

Further, since the carrot is less likely to fall on the machine body, the carrot is prevented from being damaged by the fall, and the decrease in the commercial value is reduced.

When the carrot falls on the front side of the machine body from the front end of the residual leaf processing conveyor 76, it falls on the sorting and transporting unit F. Therefore, although it is necessary to remove the residual leaf hr after harvesting, the carrot does not deviate from the transport path. Therefore, the work efficiency is unlikely to decrease.

Further, since the fallen carrot moves by driving the residual leaf processing belt 74 and moving by tilting, the movement of the carrot does not stop on the residual leaf processing conveyor 76, and there is no need to manually move the stopped carrot. , Work efficiency is improved. Further, since the residual leaf processing conveyor 76 is slightly tilted (about 2 to 5 degrees), the residual leaf processing conveyor 76 is tilted with respect to the ground even if the aircraft is tilted to the left or right side of the aircraft depending on the condition of the field or the like. Since the ginseng stays in a substantially horizontal state, the ginseng does not stay on the residual leaf processing conveyor 76 or move in the direction opposite to the transport direction of the residual leaf processing conveyor 76, and such ginseng is manually placed in the transport path. There is no need to return it, and work efficiency is improved.

With the above configuration, the residual leaf processing roller 75 constituting the residual leaf processing conveyor 76 cuts off the residual leaves of the carrot left uncut by the foliage cutting device 61, so that the work of manually cutting the residual leaves after the harvesting operation is omitted. It can be done and work efficiency is improved.

Further, since the residual leaf processing belt 74 constituting the residual leaf processing conveyor 76 is made of an elastic body such as rubber or urethane, the foliage portion h is cut by the foliage cutting device 61 and the residual leaf processing is performed even if the carrot falls. Since the belt 74 reduces the impact of dropping, the impact of dropping prevents the carrot from being damaged, and the quality of the carrot is improved.

A control configuration that more reliably cuts the foliage h and removes the residual leaf hr according to the traveling speed and the harvesting pace of the carrot by using the pull-out transport section C, the foliage cutting section D, and the residual leaf processing section E having the above configuration. Will be described.

As shown in FIG. 20, when the output of the HST 150 increases or decreases due to the detection of the lever potentiometer 13a of the traveling operation lever 13, the control device 200 calculates the traveling speed (vehicle speed) each time. At the same time, the rotary motor 615 is rotated forward or reverse according to the increase / decrease in the traveling speed and the amount of increase / decrease, and the right foliage cutting blade 60R is moved to a front-rear position suitable for the traveling speed.

As a result, when the traveling speed is increased, the cutting position of the foliage portion h by the foliage cutting device 61 becomes closer to the front side of the machine body, and the falling carrots can be received by utilizing the front-rear width on the residual leaf processing conveyor 76. The removal of the carrot from the route and the removal of the residual leaf hr prevent the succeeding carrot from coming into contact with the remaining carrot and damaging it.

Further, when the traveling speed becomes slow, the cutting position of the foliage portion h by the foliage cutting device 61 becomes closer to the rear side of the machine body, so that the residual leaf hr can be removed by using substantially the entire front-rear width of the residual leaf processing roller 75. Since it can be formed, the residual leaf hr is less likely to remain in the carrot, and the time and labor required for the removal work after harvesting are reduced.

The front-rear position of the foliage cutting blade 60R on the right side may be changed in conjunction with the operation position of the traveling operation lever 13 detected by the lever potentiometer 13a. At this time, if a cutting potentiometer 616 for detecting the rotation angle of the rotation side transmission case 609 is provided and the rotation motor 615 is stopped by detecting the cutting potentiometer 616, the foliage cutting blade 60R on the right side is set to the traveling speed. It is stopped at the corresponding appropriate position, and the cutting accuracy of the foliage h is improved.

In the above, the running speed is calculated using the lever potentiometer 13a, but the running speed is calculated by a method of calculating from the distance between two points of GPS in a predetermined time, or a left and right drive that transmits the left and right crawler 6L, 6R. A method may be used in which the rotation speed of the shafts 9 and 9 is detected by a rotation sensor or the like to calculate the traveling speed.

Alternatively, the position where the operation amount is equal to or more than the predetermined amount from the neutral position of the traveling operation lever 13 is defined as the "high-speed work area", and the position from the neutral position to the neutral position is defined as the "low-speed work area", as shown in FIG. If the right foliage cutting blade 60R moves to the front side in the "high speed work area" and the right foliage cutting blade 60R moves to the rear side in the "low speed work area", the control becomes simple and the control device 200 Can be inexpensive and the increase of extra parts can be suppressed.

Further, although the above is the control configuration by the control device 200, the vicinity of the base portion of the travel operation lever 13 and the base side of the rotation side transmission case 609 are connected by a linking wire (not shown) to reduce the operation amount of the travel operation lever 13. In addition, the front-rear position of the foliage cutting blade 60R on the right side may be changed.

In the above configuration, the linking wire is configured to rotate the rotation side transmission case 609 to the front side of the machine when the traveling operation lever 13 is operated to the speed increasing side (front side of the machine body), and the traveling operation lever 13 is set to the deceleration side (front side of the machine body). In order to rotate the rotation side transmission case 609 to the rear side of the aircraft when operated to the rear side of the aircraft, the rotation side transmission case 609 may be urged to the rear of the aircraft by a spring (not shown) or the like. ..

Alternatively, the traveling speed may be changed so that the front-rear position of the right foliage cutting blade 60R is moved back and forth based on the space between the carrot stocks by the left and right crop sensors 201.

As shown in FIG. 22, when the space between the carrots is wide, the foliage h of the subsequent ginseng is cut when the preceding ginseng is moving to the removal action area of the residual leaf hr, so that the foliage on the right side is cut. The cutting blade 60R is moved to the rear side of the machine body, and the residual leaf hr of the subsequent carrot is surely removed by the entire width of the front and rear of the residual leaf processing roller 75.

On the other hand, when the space between the stocks is narrow, the cutting interval of the foliage h of the front and rear carrots is short, and the subsequent carrots easily collide with the preceding carrot. Therefore, in order to cut the foliage h as soon as possible, the right foliage cutting blade The 60R is moved to the front side of the machine to prevent the carrots from being damaged by contact with each other.

Further, if the space between the stocks detected by the crop sensor 201 is narrow, a plurality of carrots will ride on the residual leaf processing conveyor 76. When a plurality of carrots are in contact with the residual leaf processing roller 75, the subsequent carrots are in contact with the preceding carrots and transported together, and the residual leaves are sent to the sorting and transporting conveyor 87 described later without being processed. Therefore, there is a problem that the residual leaf hr is likely to remain in the carrot, and the time and labor required for the work of removing the residual leaf hr after harvesting are increased.

Further, if a plurality of carrots are retained on the residual leaf processing conveyor 76, there is a problem that the carrots are easily contacted with the following carrots, and the carrots are easily damaged and the commercial value is easily lowered.

In order to solve this problem, as shown in FIG. 23, the control device 200 is configured to increase or decrease the rotation speed of the removal transfer motor 620 according to the stocks calculated from the detection of the crop sensor 201. When the space between the stocks is narrower than the reference value, the number of rotations of the removal transfer motor 620 is increased to increase the transfer speed of the residual leaf processing conveyor 76, so that the carrots are quickly moved to the lower side of transfer and the residual leaf processing roller 75. Can be brought into contact with the sorting and transporting conveyor 87.

Immediately after the stocks narrower than the reference value are detected, it is possible that the stocks equal to or greater than the reference value are detected. At this time, the rotation speed of the removal conveyor motor 620 is changed every time. As a result, the transportation of carrots becomes unstable, and the components of the residual leaf processing conveyor 76 are loaded, so that the durability is rapidly reduced. Therefore, once the rotation speed of the removal transfer motor 620 increases, it is preferable that the process of lowering the rotation speed is not performed for a predetermined time (ridge: 30 seconds). However, when a narrower space is detected and it is necessary to further increase the rotation speed of the removal transfer motor 620, a process of increasing the rotation speed is performed.

As a result, it is possible to prevent the carrots from staying on the residual leaf processing conveyor 76, so that it is possible to prevent the carrots that fall after cutting the foliage portion h from coming into contact with each other and being damaged, and it is possible to prevent a decrease in commercial value.

Further, since the number of carrots moving to the sorting and transporting conveyor 87 without contacting the residual leaf processing roller 75 can be reduced, the time and labor required for the work of removing the residual leaf hr after harvesting can be reduced.

On the other hand, when the space between the stocks is wide, the rotation speed of the removal transfer motor 620 is reduced to slow down the transfer speed of the residual leaf processing conveyor 76, so that the carrots are brought into contact with the residual leaf processing roller 75 for a long time to ensure the residual leaf hr. It can be removed.

Next, the sorting and transporting unit F will be described.

As shown in FIGS. 1 to 6, the transmission shaft 120 that transmits the driving force of the engine 7 is made to penetrate the lower side of the front and rear residual leaf processing frames 72 and 72 and project to the rear side of the machine body, and the transmission shaft An output sprocket 121 is provided at the rear end of the 120.

Then, the second driven sprocket 128 is rotatably mounted on the left and right sides of the machine body and above the counter sprocket 127, and the second input sprocket 126, the counter sprocket 127, and the second driven sprocket 128 are second. The transmission chain 129 is wound endlessly. The counter sprocket 127 is provided on a sorting and transporting input shaft 127a that supplies a driving force to the sorting and transporting conveyor 87, which will be described later.

With the above configuration, it is possible to compactly configure the transmission path for supplying the driving force supplied from the engine 7 to the recovery conveyor 160, the residual leaf processing conveyor 76, the residual leaf processing roller 75, and the sorting and transporting conveyor 87. The front-rear width and left-right width are suppressed, the turning performance of the aircraft is improved, and the area required for storage is reduced.

In addition, the number of parts such as sprockets and transmission chains can be reduced, so that the cost can be reduced.

Then, as shown in FIGS. 3 to 6, the front and rear first transport frames 77 and 77 are placed in the front-rear direction on the front side of the machine body and below the shoulder alignment devices 54L and 54R with respect to the residual leaf processing frame 72 on the front side of the machine body. The first transport frames 77 and 77 are arranged at predetermined intervals, and the front and rear second transport frames 78 and 78 are spaced outward in the front-rear direction at the inner ends of the first transport frames 77 and 77 (the ends on the left and right sides of the fuselage).

The front and rear first transport frames 77, 77 are T-shaped when viewed from the front (rear surface), and have an upwardly inclined portion that is inclined upward from the left and right center portion toward the left and right other sides on the left and right other sides. And.

Then, the recovery driven roller 132b is rotatably mounted on the left and right ends of the first transport frames 77 and 77 and below the transport surface of the residual leaf processing conveyor 76, that is, the upper surface of the residual leaf processing belt 74. , Driven by rotation of the recovery input shaft 123a at a position on the left and right sides of the machine body and on the recovery input shaft 123a with respect to the recovery driven roller 132b, specifically, at a position on the left and right sides of the machine body of the residual leaf processing roller 75. The recovery drive roller 132a is arranged. Further, the recovery belt 133 is wound endlessly over the recovery driven roller 132b and the recovery drive roller 132a to form the recovery conveyor 160.

The collection conveyor 160 is arranged below the transport path of the pull-out transport device 24 and the shoulder alignment devices 54L and 54R, and receives the carrot that the foliage portion h is cut and falls on the better side in the transport direction than the foliage cutting device 61. It is transported from one side on the left and right sides of the machine to the other side, and is handed over to the sorting and transporting conveyor 87. Therefore, the recovery drive roller 132a may be arranged below the recovery driven roller 132b, and the recovery conveyor 160 may be configured in a downward inclined posture toward the left and right other sides of the machine.

With the above configuration, even if the foliage h is cut and the carrot may fall during transportation, the carrot can move to the sorting conveyor 87 via the collection conveyor 160 and return to the original movement route. , The work of collecting carrots that have fallen out of the transportation route becomes unnecessary, and the labor of the worker is reduced.

Further, by arranging the collection driven roller 132 below the transport surface of the residual leaf processing conveyor 76, the carrots are not hit by the residual leaf processing roller 75 and are placed on the front side of the machine body when a large amount of carrots are supplied all at once. Even under the conditions of being extruded, the extruded carrots can be moved to the collection conveyor 160 without stagnation, so that the stagnation of the carrot harvesting work is prevented and the work efficiency is improved.

Further, when the collection conveyor 160 is tilted downward from one side on the left and right sides of the machine to the other side on the left and right sides, the carrots received by the collection conveyor 160 can roll by its own weight and move toward the sorting and transporting conveyor 87. Since the carrots stay on the conveyor 160 and are prevented from coming into contact with the carrots that fall from above while being transported to the sorting and transporting conveyor 87 side, the carrots are prevented from being damaged and the commercial value of the carrots is improved. To do.

Then, a pair of front and rear sorting drive sprockets 134, 134 provided on the sorting and transporting drive shaft 134a are arranged on the left and right other sides of the machine body and below the recovery drive roller 133. The front and rear sorting drive sprockets 134 and 134 are arranged so as to be located between the left and right sides of the output sprocket 121 and the idle sprocket 122 and above the output sprocket 121 in the rear view.

A pair of front and rear sorting idle sprockets 135, 135 are rotatably arranged on the rotating shaft 79. That is, the front and rear idle sprockets 135 and 135 rotate when receiving a driving force, but the rotation shaft 79 does not rotate.

Further, a pair of front and rear sorting driven sprockets 136, 136 are rotatably mounted on the left and right other side ends of the front and rear second transport frames 78, 78, and the front and rear sorting driven sprockets 136, 136 and the front and rear sorting driven sprockets are attached. The sorting transmission chains 137 and 137 are wound endlessly over the sorting drive sprockets 134 and 134 and the front and rear idle sprockets 135 and 135, respectively.

Of the front and rear first transport frames 72 and 72, the front and rear sorting drive sprockets 134, 134 are on the left and right sides of the machine body, that is, on the lower side of the sorting and transport conveyor 87 in the transport direction, and the front and rear sorting drive sprockets 134, The first front and rear sorting counter sprockets 139, 139 that come into contact with the lower side of the fuselage and are outside the winding range of the front and rear sorting transmission chains 137 and 137, that is, the lower side of the fuselage to prevent slack. It is mounted via the counter rotation shafts 139a and 139a.

As shown in FIG. 6, the first sorting counter sprockets 139 and 139 are not connected to each other by an axis or the like, and a space is formed between the front and rear of the first sorting counter sprockets 139 and 139. ..

Further, the front and rear first sorting counter sprockets 139 and 139 are on the left and right sides of the machine, that is, on the lower side in the transport direction of the sorting and transport conveyor 87, and on the front and rear first sorting counter sprockets 139 and 139 on the upper side of the machine. The front and rear second sorting counter sprockets 140, 140 that come into contact with the winding area 18i of the front and rear sorting transmission chains 137, 137 and bend the front and rear sorting transmission chains 137, 137 are passed through the second counter rotation shafts 140a, 140a. And attach it.

The second sorting counter sprockets 140 and 140 are not connected to each other, and a space is formed between the front and rear of the second sorting counter sprockets 140 and 140.

Further, the front and rear third counter sprockets 141 that suppress the slack of the front and rear sorting transmission chains 137 and 137 below the front and rear idle sprockets 135 and 135 and outside the winding range of the front and rear sorting transmission chains 137 and 137. , 141 are mounted via the third counter rotation shafts 141a, 141a.

Further, the front and rear sorting transmission chains are located at positions where the front and rear second sorting counter sprockets 140 and 140 come into contact with the front and rear sorting transmission chains 137 and 137, and outside the winding region of the front and rear sorting transmission chains 137 and 137. First idle rollers 142, 142 before and after contacting and bending 137, 137 are rotatably provided.

Further, second idle rollers 143 and 143 for suppressing slackening of the front and rear sorting transmission chains 137 and 137 are rotatably provided on the left and right sides of the front and rear sorting drive sprockets 134 and 134 and on the upper side of the machine.

Further, a plurality of transport bars 144 ... By which carrots are placed and transported are provided between the front and rear of the front and rear sorting transmission chains 137, 137 at equal intervals in the left-right direction, that is, at intervals L1 between the left and right, and the transport bars 144 ... For each of the plurality, receiving bars 145 ... That prevent the carrots from rolling down on the upwardly inclined portion of the sorting and transporting conveyor 87 are arranged at predetermined intervals. Further, the sorting and transporting conveyor 87 is configured by providing the second transporting frames 78 and 78 with chain covers 146 and 146 that cover the upper parts of the sorting and transmitting chains 137 and 137.

As shown in FIG. 3, there is a left-right gap between the transport start end of the sorting and transport conveyor 87 and the transport end of the collection conveyor 160 where ginseng can fall, and the transport start of the sorting and transport conveyor 87. Is located below the transfer end of the collection conveyor 160, so the carrots discharged from the transfer end of the collection conveyor 160 are transferred to the front and rear residual leaf processing frames 72 and 72 by the sorting and transfer conveyor 87. The takeover shooter 147 to be moved to the starting end is arranged in a posture of tilting downward from one left and right side of the machine to the other left and right side when viewed from the rear.

The takeover shooter 147 is made of rubber, synthetic resin, or the like so as to prevent the ginseng from being damaged even if it comes into contact with the ginseng and to prevent it from becoming a resistance even if it comes into contact with the conveyor bar 144 ... Of the sorting and conveying conveyor 87. When it is composed of a soft member, the carrot is prevented from being damaged and the commercial value of the carrot is maintained, and the drive rotation of the sorting and transporting conveyor 87 is prevented from being disturbed and the transport of the carrot is prevented from being delayed, so that the work efficiency is improved. ..

As described above, by arranging the sorting drive sprockets 134 and 134 on the left and right sides of the machine body and below the recovery drive roller 133, the transfer start end of the sorting transfer conveyor 87 is below the transfer end of the collection conveyor 160. Since the part can be located, it is possible to prevent the carrots to be transported from stagnation at the time of taking over, improving work efficiency, and the stagnation carrots come into contact with subsequent carrots, causing damage to the carrots. This prevents the commercial value from deteriorating.

Further, since the sorting and transporting conveyor 87 is located below the residual leaf processing conveyor 76, the stagnation of the transfer of carrots from the residual leaf processing conveyor 76 to the sorting and transporting conveyor 87 is prevented, so that the work efficiency is further improved. , The decrease in the commercial value of ginseng is prevented.

Further, the front and rear first sorting counter sprockets 139, 139 and the front and rear second sorting counter sprockets 140, 140 are provided on the first counter rotating shaft 139a and the second counter rotating shaft 140a, and the front and rear rotating shafts 139a, 139a, Since the 140a and 140a are not connected and a space is formed between the front and rear spaces, there is no member that gets caught when the stone moves to the front and rear spaces, so that the stones are easily removed and the sorting and transporting conveyor 87 is damaged. Be prevented.

By providing the first idle rollers 142, 142 before and after contacting the sorting transmission chain 137 and the second idle rollers 143, 143 before and after, the surface that does not convey the carrot, that is, the non-acting side is stretched and the sorting transmission is performed. Since it is possible to prevent slack that the rotation of the chains 137 and 137 stops or slows down, and an overload that can damage the sorting transmission chains 137 and 137, it is possible to match the amount of carrots contained in the storage container 97. Even if the transport end portion side of the sorting and transporting conveyor 87 is rotated up and down, the transporting speed of carrots does not change, so that the work efficiency is improved and the sorting accuracy of carrots is improved.

Further, by arranging the transport bars 144 ... With a left-right spacing L1 in the left-right direction, the earth and sand carried with the carrots and the residual leaves removed by the residual leaf treatment roller 75 are sorted and transported from the left-right spacing L1. Since it can be dropped below 87, the amount of earth and sand and residual leaves entering the storage container 97 is reduced, and carrots can be stored in the full capacity of the storage container 97. As a result, the frequency of exchanging the storage container 97 is reduced, and the work efficiency is improved.

Furthermore, by providing the receiving rails 145 ... at intervals wider than the transport bar 144 ..., even if the carrots roll on the sorting and transporting conveyor 87, the receiving rails 145 ... stop the movement of the carrots, so that the same carrots can be used many times. Since it is prevented from returning to the starting end of the conveyor, the work efficiency is improved, and when the carrot falls down, it is prevented from coming into contact with the subsequent carrot and being damaged, so that the commercial value of the carrot is maintained.

If the transport bar 144 is configured by winding a high-strength elastic body such as hard rubber or a soft elastic body such as soft rubber around the outer periphery of a rod-shaped metal, ginseng can be obtained from the collection conveyor 160 or the residual leaf processing conveyor 76. When taking over, it is possible to prevent the carrot from being damaged by the impact of contact, so the commercial value of the carrot is improved.

Further, if the receiving rail 145 is configured to attach a rivet or a bolt (not shown) from the opposite side of the transport surface, that is, from the lower side to the sorting transmission chain 137, the rivet is rivet in the winding area 18i of the sorting transmission chain 137. Since the bolts and bolts do not protrude, interference with other members is prevented, so that the sorting and transporting conveyor 87 is prevented from being damaged, and the rivets and bolts are prevented from being damaged by contact with the carrots being transported. The commercial value of ginseng is improved.

Then, a support plate 86 is attached between the left and right sides of the second transport frames 78 and 78, and an elevating cylinder 88 that moves the transfer end portion side of the sorting and transport conveyor 87 up and down between the support plate 86 and the machine frame 1 is expanded and contracted. It is freely attached to form a sorting and transporting conveyor 87 that transports carrots from one left and right side of the machine to the other left and right sides. Further, a discharge shooter 89 composed of a soft member such as a rubber plate or a vinyl chloride plate that slides and moves the carrot discharged from the transport end portion of the sorting and transport conveyor 87 to the lower portion of the transport end portion of the sorting and transport conveyor 87. Is attached with the end hanging down.

The elevating cylinder 88 may be an electric type, a hydraulic type, a pneumatic type, or may be manually expanded and contracted.

Further, an auxiliary work of sorting the carrots being transported by the sorting and transporting conveyor 87 and operating the sorting and transporting conveyor 87 at the rear of the machine frame 1 on the left and right sides of the machine and on the rear side of the sorting and transporting conveyor 87. A boarding step 90 on which a person is boarding is arranged, and an auxiliary work seat 91 is attached on the boarding step 90 and at a position close to the sorting idle sprockets 135 and 135 of the sorting conveyor 87.

Further, an elevating operation pedal 92 that expands and contracts the elevating cylinder 88 to move the transfer end portion side of the sorting and transporting conveyor 87 up and down is arranged below the transporting path of the sorting and transporting conveyor 87.

Then, the sorting and transporting unit F is configured by arranging it on the boarding step 90 and at a position where the auxiliary worker seated on the auxiliary work seat 91 can step on and operate it.

According to the above configuration, the elevating operation pedal 92 for operating the elevating cylinder 88 is provided at a position where the foot of the auxiliary worker seated on the auxiliary work seat 91 can reach, so that the auxiliary worker remains seated on the auxiliary work seat 91. The transfer end portion side of the sorting transfer conveyor 87 can be moved up and down, which improves work efficiency and reduces the labor of the operator.

Further, by providing the elevating operation pedal 92, the auxiliary worker can operate the vertical movement of the sorting and transporting conveyor 87 only with his / her feet, and the hand can be concentrated on the sorting work of the carrot being transported, so that the sorting accuracy is improved. In addition to the improvement, it is possible to prevent the hands from being pinched or cut by the constituent members of the sorting and transporting conveyor 87, and the work safety is improved.

In the configuration of the sorting and transporting unit F described above, as described above, the sorting and transporting conveyor 87 transports carrots to the storage container 97 while discharging earth and sand and residual leaves downward in the left and right spaces between the transport bars 144. Is.

Chain covers 146 and 146 are provided above the front and rear sorting transmission chains 137 and 137 for driving the sorting and transporting conveyor 87, respectively, and the earth and sand falling from above come into contact with the front and rear sorting transmission chains 137 and 137. It is preventing that.

However, from the transport end of the collection conveyor 160, the earth and sand that falls from the carrot being transported by the pull-out transfer device 24 and the earth and sand that adheres to the carrot that has fallen due to the foliage h being torn off during the transfer are downward. It may move and be discharged in a trajectory that falls into the ground, and the discharge position of earth and sand may be below the front and rear chain covers 146 and 146.

Further, the residual leaf processing roller 75 of the residual leaf processing conveyor 76 removes the residual leaves of the carrots, and then guides the carrots to the vicinity of the transport start end of the sorting and transporting conveyor 87 in the transport direction of the residual leaf processing conveyor 76. It is mounted diagonally as a reference, and the earth and sand that falls directly below from the end of the residual leaf treatment roller 75 bypasses the chain cover 146 and is between the sorting drive sprocket 134 on the rear side of the machine and the sorting transmission chain 137. It may get in.

If earth and sand, especially hard stones, get in between the sorting drive sprocket 134 and the sorting transmission chain 137, even if the stones break, the front and rear sorting transmission chains 137 will rise and the timing of not receiving the rotational drive of the sorting drive sprocket 134 will be appear.

When the sorting transmission chain 137 is lifted, the driving of the sorting and transporting conveyor 87 is temporarily stopped, and the carrots being transported flow back due to the reaction, and the carrots being transported are in contact with the following carrots and are damaged, resulting in a decrease in commercial value. Occurs.

Further, if the delivery timing of either one of the front and rear sorting transmission chains 137 and 137 is deviated, the transfer speed gradually begins to differ between the front and rear of the sorting and transporting conveyor 87. The front and rear sorting transmission chains 137 and 137 are connected by a plurality of transport bars 144 ..., and the front and rear sorting drive sprockets 134 and 134 are mounted on one sorting and transport drive shaft 134a, so that the sorting and transport conveyor 87 When there is a difference in the transfer speeds of the above, a load is applied to the transfer bar 144 ... And the sorting transfer drive shaft 134a.

As a result, the transport bars 144 ... Provided between the front and rear sorting transmission chains 137 and 137 and the sorting and transport drive shaft 134a are distorted and do not rotate normally, so that these parts must be replaced, and the work is interrupted during that time. There is a problem that the work efficiency is extremely lowered and the carrot harvest time is missed.

The sorting and transporting sprockets 134 and 134 provided on the sorting and transporting drive shaft 134a are provided with members that preferentially break when a load such as a shear pin is applied to prevent damage to other members. Since it is necessary to replace at least the shear pin, the carrot harvesting work is interrupted during the parts replacement, and the work efficiency is significantly reduced.

In order to prevent this problem, the front and rear guard covers 148 and 148 are placed on the front and rear of the front and rear first transport frames 77 and 77 and on the upper surface of the recovery belt 133 of the recovery conveyor 160, and the front side faces the rear side of the machine body. The rearward tilted posture is used, and the rear one is installed in the forward downward tilted posture toward the front side of the aircraft. One side ends of the front and rear guard covers 148 and 148 face above the transport start end side of the collection conveyor 160, and the other end ends face above the transport start end of the sorting conveyor 87.

More specifically, it extends to the left and right sides of the machine from the front and rear sorting drive sprockets 134 and 134 constituting the sorting and transporting conveyor 87, and the transporting end of the collecting conveyor 160 and the residual leaf processing of the residual leaf processing conveyor 76. The earth and sand discharged from the roller 75 are guided by the front and rear guard covers 148 and 148 to positions on the left and right sides of the machine body other than the sorting drive sprockets 134 and 134, and dropped below the sorting and transporting conveyor 87. Prevents earth and sand from being caught between the sorting transmission chains 137.

With the above configuration, the sorting transmission chain 137 is lifted from the sorting drive sprocket 134, and the transmission timing of the sorting transmission chain 137 is deviated, so-called coma misalignment is prevented, and a speed difference occurs at the front and rear positions of the sorting and transporting conveyor 87. Since it can be prevented, it is possible to prevent the transport bar 144 ... and the sorting and transporting drive shaft 134a from being distorted and the sorting and transporting conveyor 87 not being driven.

As a result, the carrot harvesting work is not interrupted, the work efficiency is improved, and the carrot can be harvested at the optimum harvest time, so that the commercial value of the carrot is improved. In addition, there is no need to replace parts, which reduces the labor of the operator.

Further, by inclining the front and rear guard covers 148 and 148 toward the central portion of the recovery conveyor 160 and the sorting and transporting conveyor 87 in the front-rear direction, the earth and sand on the guard covers 148 and 148 can be collected and transported by the recovery conveyor 160 and the sorting and transporting conveyor 87, respectively. Since it moves to the central portion in the front-rear direction of the conveyor 87, it is possible to prevent the earth and sand moving from the transport end portion of the collection conveyor 160 to the transport start end portion of the sorting and transport conveyor 87 from approaching the front and rear sorting drive sprockets 134 and 134. Sediment is prevented from being caught between the sorting drive sprocket 134 and the sorting transmission chain 137.

In addition to this, the earth and sand that moves from the residual leaf processing conveyor 76 to the sorting and transporting conveyor 87 also moves to the central part in the front-rear direction of the sorting and transporting conveyor 87, so that the falling earth and sand moves to the sorting drive sprocket 134 and the sorting and transmitting chain 137. It is prevented from being bitten between and.

The front and rear guard covers 148 and 148 are attached by inserting resin rivets into the front and rear first transport frames 77 and 77, so that the guard cover 148 is worn out and needs to be replaced. When the 148 is pulled up, it can be easily removed, so that the guard cover 148 can be easily replaced and the work efficiency is improved.

Further, if the rear end portion of the front and rear guard covers 148 and 148 in the transport direction, that is, the portion facing the transport start end portion of the sorting and transport conveyor 87 is configured to be more flexible than other parts by making a notch or the like, the front and rear guard covers Since it is possible to prevent the 148s and 148s from becoming a resistance when they come into contact with the transport bar 144 ... And the receiving rail 145 ..., it is possible to prevent an extra load from being applied to the sorting and transporting conveyor 87 and a decrease in durability.

The front-rear width of the front-rear guard covers 148 and 148 can prevent earth and sand from falling on the front-rear sorting drive sprockets 134 and 134 and the front-rear sorting transmission chains 137 and 137, and further, the front-rear center of the collection conveyor 160 and the sorting-conveyor conveyor 87. The size is about 60 to 90 mm so that the earth and sand can be easily guided toward the part. Compared to the guard cover 148 on the rear side, the guard cover 148 on the front side of the machine is less likely to allow earth and sand to enter, so the length as in the above example is not necessary, but if the length is the same for both front and rear, common parts can be used and parts. Cost reduction is planned.

Next, the configuration of the accommodating portion G will be described.

As shown in FIGS. 2 and 7 to 11, the rotating shaft 93 is penetrated in the front-rear direction of the machine body on the lower side (left and right other side portions) of the second transport frames 78 and 78 in the front-rear direction of the sorting and transport conveyor 87. The friction resistors 94 and 94 are provided on both front and rear ends of the rotating shaft 93 and on the outside of the second conveyor frames 78 and 78, respectively.

As the friction resistors 94, 94, any member such as a disc spring, a spring washer, or a rubber ring having a strong friction resistance may be used.

Further, the base sides of the front and rear hanger arms 95 and 95 are provided on both front and rear ends of the rotating shaft 93 on the outside in the front-rear direction with respect to the friction resistors 94 and 94, and the second transport frames 78 and 78 and the hanger arms 95 and 95 are provided. The hanger arms 95, 95 are configured to be movable upward or downward only when a moving force equal to or greater than the resistance is applied upward or downward due to the frictional resistance of the friction resistors 94, 94 sandwiched between the hanger arms 95, 95.

As shown in FIGS. 7, 9 and 10, the hanger arms 95 and 95 form bent portions 95a and 95a at substantially the center in the left-right direction, and extend from the bent portions 95a and 95a to the outer end of the machine body. Assuming that the shape is bent upward, that is, the shape is bent into an inverted "he" shape in front view or rear view, even if the hanger arms 95 and 95 rotate downward when the sorting and transport conveyor 87 is raised. , Even if there is no gap between the front and rear second transport frames 78 and 78 and the hanger arms 95 and 95 and the auxiliary worker extends his arm toward the transport end of the sorting and transport conveyor 87, the second transport The arms are not pinched between the frames 78, 78 and the hanger arms 95, 95, and the safety of the operator is improved.

Further, since the hanger frames 95 and 95 are located near the transport end side of the second transport frames 78 and 78, the hanger frames 95 and 95 are below the second transport frames 78 and 78 regardless of the inclination angle. Since it is located in, the sorting work space for the auxiliary worker is widened, so that the sorting accuracy is improved and the work efficiency is improved.

Then, a hanger frame 96 projecting in the front-rear direction from the front-rear end of the sorting and transporting conveyor 87 in the front-rear direction is attached to the end side of the hanger arms 95, 95, and carrots are attached to both front and rear ends of the hanger frame 96. A pair of front and rear hanging hangers 98 and 98 that hang and support the storage bag (flexible container bag) 97 that accommodates the above by hooking four points on the front, back, left and right are rotatably attached in the left and right direction.

Further, the upward inverted U-shaped (∩-shaped) outer hanging bodies 99a and 99a are welded to the outer ends of the hanging hangers 98 and 98, respectively, and the inner end of the hanging is U-shaped downward. The inner hanging bodies 99b, 99b of the mold are welded, and the hanging hooks 99f, 99f, 99f, 99f for suspending the storage bag 97 from the outer hanging bodies 99a, 99a and the inner hanging bodies 99b, 99b can be moved up and down. Attach to.

Instead of welding the outer hanging bodies 99a, 99a and the inner hanging bodies 99b, 99b, the outer end of the hanging hangers 98, 98 is bent into an inverted U shape (∩ shape), and the inner end of the machine is bent. May be bent into a U shape so that the hanging hooks 99f, 99f, 99f, 99f can be attached so as to be movable in the vertical direction.

The hanging hangers 98, 98 have four corners of the storage bag 97, front and rear outer suspension bodies 99a, 99a, and front and rear so that the upper opening of the storage bag 97 to be hung is substantially quadrangular in a plan view. It is hung by the inner hanging bodies 99b, 99b.

As shown in FIG. 10, the hanging hangers 98, 98 are removed from the hanger frame 96, the outer hanging bodies 99a, 99a are hooked on the front and rear ends of the hanger frame 96, and the inner hanging bodies 99b, 99b are attached. When the sorting conveyor 87 is rotated upward by hooking on the support protrusion 119 provided at the outer end of the collection table 118, which will be described later, the collection table 118 is pulled up by the hanging hangers 98 and 98 and automatically accommodated, that is, the accommodation posture. Since the posture can be substantially orthogonal to the machine frame 1, it is not necessary to manually lift the collection table 118, and the labor of the operator is reduced.

Further, when the sorting and transporting conveyor 87 is rotated to the upper limit to be in the stored state, the hanging hangers 98 and 98 are in an orthogonal posture with respect to the machine frame 1, so that there is no member protruding to the outside of the machine frame 1 during storage. , It is possible to prevent the protruding member from being damaged during storage and to prevent extra storage space from being taken.

When the collection table 118 is pulled up by the hanging hangers 98, 98, the posture of the hanging hangers 98, 98 is a posture in which the storage bag 97 is rotated by about 180 degrees with reference to the posture of hanging the storage bag 97 in the open state.

Then, the lower limit regulation that regulates the downward rotation by receiving the front and rear hanger arms 95 and 95 on the front and rear outside of the transport end portion of the second transport frames 78 and 78 and in the direction outside the machine body from the mounting position of the rotating shaft 93. The protrusions 100 and 100 are attached. Further, on the outside of the second transport frame 78 on the front side of the machine body, above the lower limit regulation protrusion 100 on the front side of the machine body and near the rotation shaft 93, the upper limit regulation that receives the hanger arm 95 on the front side of the machine body and regulates the upward rotation. The protrusion 101 is attached.

Further, an adjustment knob 102 having a hole (not shown) with a female screw engraved on the rear side or both front and rear sides of the rotating shaft 93 and a male screw (not shown) screwed into the hole is formed. The frictional resistance is changed by inserting and rotating the adjustment knob 102 to change the front-rear distance between the second sorting frames 78 and 78 and the hanger arms 95 and 95 sandwiching the frictional resistors 94 and 94 in between. The configuration is to be used.

If the adjustment knob 102 is provided at the rear end of the rotating shaft 93, it is easy for the auxiliary worker on the auxiliary work seat 91 to operate, and if it is provided at the front end of the rotating shaft 93, it gets on the control seat 11. It becomes easy for the operator to operate it, and it becomes easy to adjust the frictional resistance force of the frictional resistors 94, 94.

Further, a slide shaft 103 slidable in the front-rear direction is provided below the second transport frame 78 on the transport end side of the sorting and transport conveyor 87 and on the rear side of the machine body with respect to the rotating shaft 93, and the slide shaft 103 is provided. A spring 104 that applies an urging force toward the front side of the machine body is attached. Then, an auxiliary hook 105 is provided at the front end of the spring 104 to prevent slack by suspending the front-rear middle portion inside the body of the storage bag 97 that enters the lower part of the sorting and transporting conveyor 87, and the rear side of the slide shaft 103. A slide knob 106 that allows the operator to slide the slide shaft 103 back and forth is attached at the end and outside the second frame 78.

Then, the slide knob 106 is provided with a hook lever 106a that makes it easy for the operator to operate the slide knob 106 by hand, and the hook lever 106a is directed to the sorting and conveying conveyor 87 side, that is, the inside of the machine body at the base of the hook lever 106a. Install the urging torque spring 106b.

Since the hook lever 106a is brought into contact with the inside of the body of the storage bag 97 during the harvesting operation to urge the inside of the body of the storage bag 97, it is possible to prevent the inside of the body of the storage bag 97 from being loosened. , It is prevented that the carrot enters the slack and the storage capacity is wasted, the storage bag 97 does not need to be replaced frequently, and the work efficiency is improved. Further, if a tube made of a soft material such as rubber is attached to the surface of the hook lever 106a, it is possible to prevent the carrot contained in the storage bag 97 from coming into contact with the hook lever 106a and being damaged, so that the commercial value of the carrot is increased. improves.

In addition to this, since the visor plate 126 rotates together with the hanger frame 96 and is always in a substantially horizontal posture with the hanging hangers 98 and 98, direct sunlight is contained in the storage bag 97 even if the sorting and transporting conveyor 87 is moved up and down. It is difficult to enter, the deterioration of carrots can be prevented and the commercial value can be improved, and the visor plate 126 is prevented from hindering the movement of the hanging hangers 98 and 98.

Further, since the hook lever 106a is pressed against the bottom of the sorting and transporting conveyor 87 by the force of the torque spring 106b during non-working (when stored), the hook lever 106a is prevented from protruding to the outside of the machine body. The hook lever 106a is prevented from being damaged by contact during storage, and extra storage space is not taken up.

If the slide shaft 103 is provided from the rear end of the sorting and transporting conveyor 87 to the same or slightly forward side of the front and rear intermediate portions of the sorting and transporting conveyor 87 when not operated, the position of the auxiliary hook 105 can be easily aligned. Further, the slide shaft 103 may be provided from the front side to the rear side of the machine body, and in this case, the operator boarding the control seat 11 can operate the slide shaft 103.

Then, as shown in FIG. 11, the suspension band hook 107 for hooking the suspension band 97i inside the body of the storage bag 97 below the sorting and transporting conveyor 87 and on the upper side of the sorting and transporting conveyor 87 in the transporting direction than the rotating shaft 93. The storage bag hanging device 85 is configured by arranging the hanging band pin 108 for hooking the hanging band 97o on the outer side of the machine body toward the upper side of the machine body on the upper part of the hanger frame 96.

The suspension bands 97i and 97o on the outside of the machine body are members for hanging the storage bag 97 containing the carrot by hooking it on a forklift or a hoist.

Next, the operation of the accommodating portion G will be described.

At the start of the carrot harvesting operation, the sorting and transporting conveyor 87 is lowered to the lowest position in order to minimize the falling distance of the carrots from the transporting end of the sorting and transporting conveyor 87 to the storage bag 97. Further, the four corners of the storage bag 97 are hooked on the hanging hooks 99f, 99f, 99f, 99f provided on the outer hanging bodies 99a, 99a and the inner hanging bodies 99b, 99b of the front and rear hanging hangers 98, 98, and the upper side thereof. The opening is substantially square in plan view.

Then, the front and rear hanger arms 95 and 95 are rotated upward until they come into contact with the upper limit regulation protrusion 101, and the front and rear hanging hangers 98 and 98 are tilted upward from the inner end of the machine body toward the outer end of the machine body. To do. Since the hanging hangers 98 and 98 are in a posture of tilting upward toward the outside of the machine, the suspended storage bag 97 also tilts upward from the inside end of the machine toward the outside end of the machine. Become a posture.

At this time, of the suspended storage bags 97, the inside of the machine body where carrots are discharged from the transport end side of the sorting and transport conveyor 87 is slackened, so that the vertical length is shortened, and the outside of the machine body is almost slackened, so that the top and bottom are raised and lowered. The length becomes longer. The storage bag 97 is flexibly made of a cloth material, synthetic fibers, or the like.

Further, the outer end of the discharge shooter 89 is inserted into the inner end of the storage bag 97, and the inner end of the storage bag 97 is inserted below the end side of the conveyor 87 for sorting and transporting the storage bag 97. The auxiliary hook 105 is hooked on a suspension hole (not shown) formed at a substantially central portion in the front-rear direction. Further, the hanging band 97i inside the body of the storage bag B is hooked on the hanging band hook 107, and the hanging band 97o outside the body is hooked on the hanging band pin 108 on the hanger frame 96.

The hanger arms 95, 95 are held in an inclined posture set by the operator due to the frictional resistance force of the friction resistors 94, 94, but if the hanger arms 95, 95 start to rotate downward without permission when left unattended, the adjustment knob 102 is rotated. Then, the frictional resistance force of the frictional resistors 94,94 arranged between the second transport frames 78,78 and the hanger arms 95,95 is adjusted. When the adjustment knob 102 is rotated in the tightening direction, the contact area and contact pressure of the friction resistors 94 and 94 increase, the friction resistance becomes stronger, and the hanger arms 95 and 95 are prevented from moving arbitrarily. When rotated in the loosening direction, the contact area and contact pressure of the friction resistors 94 and 94 decrease, and the friction resistance becomes weak.

Further, when the harvesting work progresses and the amount of carrots contained in the storage bag 97 exceeds a certain amount, the auxiliary worker steps on the extension side of the elevating operation pedal 92, extends the elevating cylinder 88, and extends the elevating cylinder 88 to the sorting and transporting conveyor 87. Raise the transport end side.

While the sorting and conveying conveyor 87 is rising, the force that the hanger arms 95 and 95 try to lower exceeds the frictional resistance force of the friction resistors 96 and 96, so that the hanger arms 95 and 95 are lowered. The lowering of the hanger arms 95 and 95 occurs only while the sorting conveyor 87 is raised to secure the carrot storage space in the storage bag 97.

When the hanger arms 95, 95 rotate downward, the hanging hangers 98, 98 rotate around the hanger frame 96 as a fulcrum, the outside of the hanging hanger 98.98 rotates downward, and the inside of the body moves downward. Rotate upward. Since the outside of the storage bag 97 is located upward at the stage of installation, there is almost no change in the position, but the inside of the body is pulled up by the movement of the hanging hangers 98 and 98. As a result, the slack generated inside the body of the storage bag 97 is eliminated according to the amount of increase.

Since there is almost no change in the head between the transport end of the sorting and transport conveyor 87 and the storage bag 97 due to this operation, and the end of the discharge shooter 89 hangs down inside the storage bag 97, the storage bag 97 is inserted. It does not protrude from 97.

Further, every time the harvesting work progresses and the amount of carrots contained in the storage bag 97 exceeds a certain amount, the transport end portion of the sorting and transport conveyor 87 is raised, the hanger arms 95 and 95 are rotated downward, and the storage bag 97 is rotated. The inside of the aircraft is pulled upward to secure the storage space for carrots in the storage bag 97, and the pile of carrots biased to the inside of the aircraft is destroyed.

Then, when the sorting and transporting conveyor 87 is rotated upward and the hanging hangers 98 and 98 are in a substantially horizontal position, the slack inside the body of the storage bag 97 is eliminated, and the vertical heights inside and outside the body are substantially the same. Become. In this state, since about 200 kg of carrots are stored in the storage bag 97, the operator stops the traveling of the aircraft and lowers the storage bag 97 to the outside of the aircraft. At this time, the hanger arms 95 and 95 are configured to come into contact with the lower limit regulation protrusions 100 and 100.

However, if it takes a lot of time to replace the storage bag 97, such as when all the carrots in the field can be harvested in a few meters, the lid that closes the upper opening of the storage bag 97 is hung from the hanger 98,98. By hooking on the outer hanging bodies 99a and 99a and increasing the vertical height of the storage bag 97 from the outside of the body to the vicinity of the central part in the left-right direction, it becomes possible to store a few meters (several kg) of carrots. The trouble of replacing the bag 97 can be saved, and the work efficiency is improved.

Even in this state, there is almost no change in the head between the transport end portion of the sorting and transport conveyor 87 and the storage bag 97.

Then, when the storage capacity of the storage bag 97 is full, the machine body, the pull-out transport device 24, the sorting and transport conveyor 87, etc. are stopped, the storage bag 97 is removed from the hanging hooks 99f, 99f, 99f, 99f, and the hook lever 106a is removed. Operate and pull the auxiliary hook 105 to the rear of the machine via the slide knob 106 to remove the auxiliary hook 105 from the storage bag 97. When the auxiliary hook 105 is released from the hook lever 106a by the urging force of the spring 104, the auxiliary hook 105 automatically returns to the substantially central portion in the front-rear direction of the sorting and transporting conveyor 87 and the storage bag 97 when mounted.

Further, by operating the operation handle 116 to lower the mounting table 112 forward or backward, the storage bag 97 containing the carrot slides down the mounting table 112 by its own weight, so that the storage bag 97 is lowered to the front side of the machine body. When the machine body is retracted, and when the storage bag 97 is lowered to the rear side of the machine body, the body is moved forward, so that the storage bag 97 containing about 200 kg of carrots is lowered from the storage portion G and installed in the field.

Then, when the harvesting work is completed, the hanger arms 95 and 95 are brought into contact with the upper limit regulation protrusion 101 again, and the sorting and conveying conveyor 87 is rotated upward to the uppermost position.

With the above configuration and operation, there is almost no slack on the outside of the housing bag 97 from the start of work to the time of replacement, so that it is possible to prevent carrots from entering the slack and reducing the storage capacity of the storage bag 97. The frequency of replacement of the bag 97 is reduced, the work efficiency is replaced, and the labor of the operator is reduced.

With the conventional method of attaching the storage bag, slack is generated on both the inside and outside of the machine, so carrots enter this slack, and even if the storage bag is lifted, the slack cannot be removed, the amount of storage at one time is reduced, and the storage bag is replaced. The frequency was high.

In addition, the slack generated in the storage bag could be eliminated by moving the sorting and transporting conveyor up and down to secure the storage space, but the operator had to operate the sorting and transporting conveyor every time the slack was removed. It was reducing efficiency. Especially in the case of an auxiliary worker performing sorting, the sorting accuracy during operation was lowered.

Since the head between the transport end of the sorting and transport conveyor 87 and the left and right sides of the storage bag 97 is always substantially constant, it is possible to prevent the carrot from being damaged by the impact of dropping, and the commercial value of the carrot is improved. To do.

Further, normally, the rotation of the hanger arms 95 and 95 is regulated by the friction resistors 96 and 96, and the hanger arms 95 and 95 rotate downward only while the sorting conveyor 87 is raised. By operating the sorting and transporting conveyor 87 according to the change in the ginseng capacity of the storage bag 97, the inside of the hanging hangers 98 and 98 can be moved upward, so that the storage capacity of the storage bag 97 is automatically adjusted. Since the slack inside the body of the storage bag 97 is automatically eliminated, it is not necessary to move the sorting and transporting conveyor 87 up and down to remove the slack, and the work efficiency is remarkably improved.

Further, by providing the upper limit regulating projection 101 for determining the upper limit of the hanger arms 95 and 95 in the upward tilting posture on the second transport frame 78 on the front side of the machine body, the operator can easily understand the position where the hanger arms 98 and 98 are set. The positions of the hanger arms 95, 95 can be determined so that the storage bag 97 is full.

In addition, since the upper limit regulating protrusion 101 is provided only on the second transport frame 78 on the front side of the machine body, the upper limit regulating protrusion 101 is within the working range of the auxiliary worker who sorts the carrots being transported by the sorting and transporting conveyor 87. Since it does not exist, it is prevented that the auxiliary worker is hit or caught on clothes when operating, and the burden on the worker is reduced.

The lower limit regulating members 100 and 100 are also provided on the second transport frame 78 on the rear side of the machine body, but the positions where they are provided are the inner ends of the machine body of the hanging hangers 98 and 98, and the normal sorting work is completed. There is no problem because it does not interfere with the operation of the auxiliary worker because it is in the area where it exists.

In order to prevent the operator from forgetting to bring the hanger arms 95 and 95 into contact with the upper regulation protrusion 101, it is possible to prevent forgetting to set by writing a cautionary note on the second transport frame 78 on the rear side.

Then, the outer hanging bodies 99a, 99a are provided at the outer end of the hanging hangers 98, 98 with the outer hanging bodies 99a, 99a facing upward, and the inner hanging bodies 99b, 99b are provided at the inner end of the machine, thereby suspending the inside of the machine. Since the hanging hooks 99f and 99f are located below the hanging hooks 99f and 99f on the outside of the machine body, the difference in vertical height between the outside of the body and the inside of the body of the storage bag 97 becomes large when the storage bag 97 is installed. , Carrots are less likely to spill from the outside of the storage bag 97.

Further, if the left and right ends of the hanging hanger 98 are bent to form the outer hanging body 99a and the inner hanging body 99b, the hanging hanger 98 can be made of a single bar, so that the cost can be reduced.

Then, the hanging band 97i provided inside the body of the storage bag 97 is hooked on the hanging band hook 107 under the sorting and transporting conveyor 87, and the hanging band 97o provided on the outside of the body is hooked on the hanging band pin 108 on the hanger frame 96. As a result, the hanging bands 97i and 97o pull the storage bag 97, so that the slack generated in the storage bag 97 can be reduced.

Further, by hooking the auxiliary hook 105 in the hole in the substantially central portion of the storage bag 97 in the front-rear direction, it is possible to reduce the slack that occurs in the substantially central portion of the accommodation bag 97 in the front-rear direction, so that the carrot is inside the machine body. It is difficult to get into the slack of the carrot, and a sufficient storage space can be secured.

Then, when the slide knob 106 is pulled to the rear of the machine body, the slide shaft 103 slides to the rear of the machine body and the auxiliary hook 105 is disengaged from the storage bag 97. Therefore, the storage bag 97 filled with carrots and the sorting and transporting conveyor 87 are transported. Since the auxiliary hook 105 can be removed without entering the narrow space created between the lower end portion and the lower end portion, the work efficiency is improved and the labor of the operator is reduced.

Further, when the hanger arms 95 and 95 are brought into contact with the upper limit regulation protrusion 101 and the sorting and conveying conveyor 87 is rotated to the uppermost position, the hanging hangers 98 and 98 rotate to rotate the outer ends of the hanging hangers 98 and 98. Since the portion is located inside the end portion of the airframe frame 1, the hanging hangers 98, 98 protruding from the airframe frame 1 do not hit the wall or the like, and damage to the airframe is prevented.

Further, since the end portion of the discharge shooter 89 is hung inside the storage bag 97, there is no space between the discharge shooter 89 and the storage bag 97 where carrots can fall, so that the carrot is discharged from the sorting and transporting conveyor 87. It is possible to prevent the carrots from falling and improve the commercial value of the carrots.
When the width of the discharge shooter 89 in the front-rear direction of the machine body is substantially the same as the width of the sorting and transport conveyor 87 in the front-rear direction of the machine body, the above-mentioned effect of preventing the carrot from falling is further improved.

Next, the configuration of the loading / discharging unit H will be described.

As shown in FIGS. 2, 17 and 18, a mounting / discharging frame 109 projecting to the outside of the machine is provided at the rear left and right sides of the machine frame 1 and accommodated in the mounting / discharging frame 109 so as to be vertically rotatable. A mounting table 110 is provided. The accommodating platform 110 rotates around the base on the front side of the machine body, and when rotated downward, the rear side of the machine body rotates until it touches the field scene, and when it is rotated upward, the accommodating platform 110 and the machine frame 1 move. It shall be lined up in a substantially horizontal position.

Then, a mounting / discharging actuator 111 for rotating the storage / discharging table 110 is provided at the inner end of the machine body of the previously described mounting / discharging frame 109, and an operation switch (not shown) of the mounting / discharging actuator 111 is provided. The operation switch is provided on either or each of the control panel 12, the second transport frame 78 on the side where the auxiliary work seat 91 is provided, or the inner end of the machine body of the above-mentioned pre-installed discharge frame 109.

The storage platform 110 is provided with a front wall portion 110a for receiving the storage bag 97 on the front side of the machine body, and left and right side walls 110b and 110b on both the left and right sides of the machine body, and the rear side of the machine body is a discharge space portion 110c for discharging the storage bag 97. ..
