The left and right one side ends of the output shaft 6a extending from the case 6 to the left and right sides are penetrated. Further, a base portion of a rotating rod 100 for rotating the rocking sour 29 in the front-rear direction in a plan view is provided on the left and right sides of the support plate 99, that is, on the outer side of the machine body, and on the other side of the support plate 99, that is, the machine body. A base portion of a rocking rod 101 for rocking the rocking solitary 29 in the longitudinal direction of the machine body is provided inside.

The rocking rod 101 is also provided on the left and right other sides of the machine body, and the rocking solitary 29 on the left and right other sides is similarly rocked.
As shown in FIGS. 6 to 8, the rotating rod 100 includes a rotating eccentric cam 100a into which the output shaft 6a is inserted, and a rotating shaft portion 100b in the front-rear direction attached to the rotating eccentric cam 100a. A pillow ball 100c is provided at the front end of the pivot shaft 100b. The swing rod 101 is configured by providing a swing shaft portion 101b between a swing eccentric cam 101a into which the output shaft 6a is inserted and a mounting boss 101c on the front side of the machine body.

  Then, the pillow ball 100 c provided at the front end of the rotating rod 100 is provided on the rotating plate 103 provided on the upper part of the vertical rotating arm 102. The rotating plate 103 is detachably attached to the upper end of the sour rotating arm 102, and when mounted, the rotating plate 103 rotates in conjunction with the rotating rotating plate 103. In addition, a rotation connection pin 103a is provided on one side of the rotation plate 103 on the left and right sides (outside the machine body), and the rotation connection pin 103a is inserted and connected to the pillow ball 100c.

  Thereby, when the rotating rod 100 is rotated by the output shaft 6a, the rotating plate 100 reciprocates in the front-rear direction by the eccentric rotation of the swing eccentric cam 100a, and is connected to the pillow ball 100c by the front-rear reciprocating movement. 103 is reciprocatingly rotated in the front-rear direction in a plan view, and is configured to reciprocally rotate in the front-rear direction in conjunction with the solitary rotation arm 102 provided at the lower portion of the rotation plate 103.

  Further, a bifurcated solitary support arm 105 is provided in the vertical direction below the sour rotating arm 102, and the upper side of the swinging soli 29 is inserted into the bifurcated portion of the sora support arm 105. And connecting holes (not shown) respectively formed in the swinging sour 29, and fixing members 29a such as bolts and nuts are inserted into the connecting holes to fix the swinging sour 29. The swinging soiler 29 is configured such that the lower side is bent toward the pulling and conveying area R and formed into an L shape (reverse L shape) when viewed from the front, and enters the soil from the side of the ridge.

  A plurality of the connection holes are formed in the vertical direction on either or both of the support arm 105 and the swing soiler 29, and the working height of the swing soiler 29 is changed by changing the combined connection hole. If possible, it can be set to an appropriate height that meets conditions such as the vertical length of the crop to be harvested, the depth of burial in the soil, or the presence or absence of multi-film, and the soil to be harvested is not damaged. Therefore, the quality of the crop is maintained and the work efficiency is improved.

  In addition, a protective cover (not shown) is provided at least at the connecting portion between the pillow ball 100c and the rotating connecting pin 103a to stop the rotating operation by biting a foliage portion or sand into the connecting portion, or the biting sand, etc. This prevents the pillow ball 100c and the rotation connecting pin 103a from being worn away.

  A hollow solitary swinging case 107 is provided on the outer periphery of the sour rotating arm 102 and between the rotating plate 103 and the upper and lower support arms 105. A swing connecting pin 106 for inserting the mounting boss 101c of the swing rod 101 is provided on the upper end side of the inner side of the body of the rocker swing case 107.

  Even when the solitary rocking case 107 is moved in the front-rear direction by the rocking rod 101, the solitary rotating arm 102 is interlocked with the rotation of the rotating plate 103 by the rotating rod 100. It is set as the structure which can reciprocately rotate to a direction.

  Thus, when the swinging rod 101 is rotated by the output shaft 6a, the swinging eccentric cam 101a is reciprocated in the front-rear direction by the eccentric rotation of the swinging eccentric cam 101a, thereby reciprocatingly swinging the solitary rotating arm 102 in the front-rear direction. .

  With the above configuration, when the output shaft 6a rotates, the rotating rod 100 is reciprocated in the front-rear direction, and along with this reciprocating movement, the soli-rotating arm 102 reciprocally rotates in the front-rear direction in plan view. Since the swinging sour 29 provided on the arm 105 can be rotated in the front-rear direction in a plan view, the soil can be dug reliably from the base side to the end side of the swinging sour 29. The soil is prevented from resisting when the onion is pulled out, and the work efficiency is improved.

  In particular, since the soil around the onion planted at a position away from the mounting base of the swinging soiler 29 in the body inner direction, that is, the onion planted near the center in the left-right direction of the kite, can be easily unwound. The efficiency is improved, the onion is prevented from being left unchecked, and the time and labor for the operator to manually harvest the onion are reduced.

  In addition, since the swinging sour 29 rotates about the left and right side of the swinging arm 102 as a fulcrum, the amount of rotation increases toward the other left and right sides of the swinging soy 29, so that the width before and after unraveling the soil becomes wider. The soil is dug more reliably and the efficiency of the onion pulling and harvesting work is improved.

  Further, when the output shaft 6a rotates, the rocking rod 101 is reciprocated in the front-rear direction, so that the rocking soiler 29 can be swung in the front-rear direction. As a result, the onion is prevented from being pulled out and damaged, and the operator does not need to dig up the onion, thereby reducing the labor of the operator.

  Furthermore, the rocking rod 101 is swung in the front-rear direction by the rocking rod 101 and the rocking sour 29 is swung in the front-rear direction by the rotating rod 100, so that Since the soil can be unraveled reliably, it is possible to harvest multiple onions without losing pulling out, improving work efficiency and eliminating the need for the operator to manually harvest the remaining onions, Save time and effort.

  The swinging soiler 29 enters the cage as the aircraft moves forward, and unravels the dredged soil from the soil. In order to prevent it from coming into contact with the onions planted in the soil, Pass through. When the rocking soy 29 passes under the onion, the rocking soy 29 can be brought into contact with a thin hair root extending from the lower part of the onion into the soil and the root can be cut when the soil is unwound. Therefore, the labor of removing the hair root from the onion after harvesting is reduced.

  However, in the conventional configuration, when the soil is difficult to unravel due to soil quality, onion growth state, etc., the rocking soiler 29 is located around the onion that is vegetated near the center of the straw away from the mounting base of the rocking soiler 29. Since it does not swing back and forth almost back and forth, the soil is difficult to unravel and the onion is not pulled out, and the roots are not cut, and many remaining roots after harvesting must be removed, which is necessary for the removal work There is a problem that time and labor increase.

  The onion root of the onion has innumerable thin roots at the center of the lower bulb, but it grows at a position close to the edible part with commercial value, so it can be removed without damaging the edible part. Since a precise cutting is necessary, the time and labor required for the removal work tend to increase as the remaining amount increases.

  In the configuration of the present application, the swinging soluer 29 is rotated in the front-rear direction in a plan view by the rotating rod 100, and the end side of the swinging soluer 29 is rotated back and forth more significantly than the base side with the sour rotating arm 102 as a fulcrum. Since it is configured to move, the oscillating soiler 29 can remove the roots of the onion while digging the soil near the center of the reed, thus reducing the labor and time for removing the reeds from the harvested onion. .

  Further, in this configuration, a solitary rocking case 107 is provided on the outer periphery of the solitary rotating arm 102, and even if the rocking rod 101 reciprocates the solitary rocking case 107 in the front-rear direction, the solitary rotating arm 102 does not rotate. Since the structure is configured to rotate in conjunction with the rotation of the moving plate 103, the reciprocating rocking in the front-rear direction and the reciprocating rotation in the front-rear direction of the rocking soiler 29 interfere with each other. It is possible to prevent the efficiency of removing the root of the hair from being lowered.

  The working height of the rocking solubilizer 29 is such that the connecting holes formed in the soli support arm 105 and the rocking solubilizer 29 are combined, and fixing members 29a such as bolts and nuts are inserted into the connecting holes. However, if the vertical position needs to be changed significantly when adjusting to the height of the ridge or the vegetation position of the onion, the above adjustment method may not be able to cope with it.

  In order to solve this problem, in this case, as shown in FIGS. 1 to 3, 6, and 7, the left and right sides on the rear side of the body frame 1 and the left and right sides of the drive wheels 84 </ b> R on the left and right sides. An adjustment support plate 108 is provided on the other side facing downward, and a rear end portion of the vertical adjustment cylinder 109 is rotatably attached to the adjustment support plate 108. A vertical adjustment lever (not shown) for operating expansion / contraction of the vertical movement adjustment cylinder 109 is provided in the vicinity of the travel operation lever 10. A front end portion of the vertical adjustment cylinder 109 is rotatably provided at a lower portion of the relay rotation arm 110, and a rear end portion of the vertical adjustment arm 111 is provided at an upper portion of the relay rotation arm 110. A front end portion of the vertical adjustment arm 111 is connected to the solar swing case 107.

  At this time, the front end of the vertical adjustment arm 111 is located below the vertical center position of the rocker swing case 107 and higher than the soli support arm 105 so as to increase the vertical adjustment amount of the rocking soiler 29. It shall be provided above. Further, the front end of the vertical adjustment arm 111 is constituted by a bifurcated branch support 111a, and a solitary swing case 107 is disposed in a space portion of the branch support 111a. 112 is configured to be able to rotate by making contact with the rocker swinging case 107.

  Accordingly, when the vertical adjustment cylinder 109 is expanded and contracted, the relay rotation arm 110 is rotated in the front-rear direction, and the vertical adjustment arm 111 is moved in the front-rear direction in conjunction with the vertical movement of the sor swing case 107. It becomes composition.

  The vertical adjustment cylinder 109 may be electrically operated or hydraulic. However, if it is replaced with an expansion / contraction rod (not shown) that expands and contracts when the handle is turned, the labor required for the operation increases, but an energizing cable or transmission Oil pipes are no longer required, and costs can be reduced.

  As described above, the operating position of the rocking soiler 29 can be appropriately changed in accordance with the height of the reed and the depth of the soil in which the onion is buried, so that the rocking soiler 29 contacts the onion in the soil. Damage to the product, and the commercial value of the onion is improved.

  Moreover, since the rocking soiler 29 is too far from the onion in the vertical direction, the soil around the onion cannot be unraveled, and the onion can be prevented from remaining on the field without being pulled out, so it is necessary for the operator to harvest the onion manually. The labor of the operator is reduced.

Further, since it is possible to prevent the beard root of the onion from being drawn and harvested without being cut, the time and labor required for the work of removing the root from the onion after harvesting can be measured.
With the above configuration, under the four-row planting work conditions, the soil around the two onions is dissolved to facilitate pull-out harvesting, and the roots are removed to reduce the labor required for post-harvest preparation work. It becomes possible to do.

  The upper ends of the left and right rotation shafts 16a, 16a of the left and right pulling driven pulleys 16, 16 provided at the front end of the pulling and conveying apparatus 20 are protruded upward through the left and right pulling covers 19, 19, Left and right transmission cases 34 and 34 having left and right input pulleys 31 and 31 mounted in the front side of the machine body are provided at the upper ends of the left and right pull-out covers 19 and 19 at the upper end portions of the left and right rotating shafts 16a and 16a.

Each of the pulleys 36 and 36 is mounted, and the left and right laterally raised frames 37 and 37 to which the left and right laterally driven drive pulleys 36 and 36 are mounted are arranged in a rear-upward inclined posture. The rearward tilt angle of the left and right laterally raised frames 37, 37 is set larger than the rearward tilt angle of the left and right pull-out frames 15, 15. Then, left and right laterally driven driven pulleys 38, 38 are rotatably provided at the lower ends of the left and right laterally raised frames 37, 37, respectively, and the left and right laterally driven drive pulleys 36, 36 and the left and right laterally raised pulleys are provided. A plurality of lateral pulling tension pulleys (not shown) are provided between the upper and lower sides of the driven pulleys 38 and 38. Further, the left and right lateral pulling drive pulleys 36, 36, the left and right horizontal pulling driven pulleys 38, 38, and a plurality of horizontal pulling tension pulleys, a plurality of horizontal pulling lugs 39a formed of an elastic material such as rubber or sponge. Left and right laterally raised belts 39, 39 are wound around the left and right laterally raised belts 39, 39, and left and right laterally raised frames 37, 37 are parallel to the left and right laterally raised frames 37, 37. By providing the cover 40, 40, a lateral pulling device 41 is configured.

  The laterally raised lugs 39, 39... Provided on the left and right laterally raised belts 39, 39 are arranged at positions where their tip portions are close to the drawing conveyance area R of the drawing conveyance device 20 and are not in contact with each other.

  The above configuration prevents the lugs 39a and 39a from coming into contact with each other, preventing the fall of the stems and leaves caused by the impact of the contact, and reliably pulling the onion from the field by the pulling and conveying device 20. It can be pulled out and work efficiency is improved.

  Further, upper ends of the left and right second universal joints 42, 42 are provided on the lower side of the left and right output pulleys 32, 32, and left and right shoulder alignment drive pulleys 43, 43 are provided at the lower ends of the second joints 42, 42, respectively. Provide each. The left and right shoulder alignment pulleys 43, 43 are provided with front end portions of left and right upper shoulder alignment frames 44, 44 and left and right lower shoulder alignment frames 45, 45 at the upper and lower portions of the left and right shoulder alignment pulleys 43, 43, respectively. 44, and left and right shoulder-aligned driven pulleys 46, 46 are rotatably mounted on the rear end portions of the left and right lower shoulder-aligned frames 45, 45, respectively. The left and right shoulder alignment belts 50 and 50 are wound around the pulleys 46 and 46 in an endless manner.

  Further, in the branch transmission case 6, a first cutting transmission case 47a is rotatably provided on the other side of the left and right sides of the body relative to the central part in the left and right direction of the body, and a second cutting transmission is provided at the front end of the first cutting transmission case 47a. A case 47b is rotatably provided, and a cutting bevel case 48 is disposed in the left-right direction of the machine body at the front end portion of the second cutting transmission case 47b. A cutting rotary blade 49 for cutting the onion stem and leaves is detachably provided at the end of the cutting bevel case 48, and the cutting fixed blade (not shown) is placed on the upper shoulder alignment frame 44 on one side of the left or right side. ) Is detachably provided, the rise of the onion being transported by the pulling and transporting device 20 is limited by the lower shoulder alignment frames 45 and 45, and the cutting position of the foliage portion is cut to a predetermined position before cutting. 51 is configured.

  The first cutting transmission case 47a and the second cutting transmission case 47b can be configured such that the cutting height of the cutting rotary blade 49 can be freely changed by rotating in the vertical direction, so that the onion can be When the sun is dried, the cutting height is slightly left (about 3 to 5 cm), and when the onion is hung on a dryer or the like and dried, the foliage for hanging the onion is greatly increased (about 10 to 10 cm). 20 cm) The remaining cutting height.

  With the above configuration, the foliage portion is cut into the cutting rotary blade 49 and the cutting fixed blade after the cutting position is aligned to a predetermined position, so that the foliage portion is largely left uncut and the operator manually removes the foliage portion later. Since the cutting work is not necessary, the labor of the operator is reduced and the work efficiency is improved.

  Further, since the onion can be prevented from being lifted too much and the cutting rotary blade 49 and the cutting fixed blade can cut the spherical portion of the onion, so-called edible portion, the onion is not damaged and the commercial value of the onion is maintained. The

  In addition, since this cutting fixed blade overlaps with the cutting rotary blade 49 on the drawing conveyance area R, it is configured to cut across the foliage portion of the onion, and can be cut without escaping the foliage portion. The part remains without being cut, and the operator does not need to manually cut the remaining leaves.

  However, when cutting off the leaves and leaves of the onion, the edible part having the commercial value is damaged if it is cut from the vicinity of the spherical part, and the quality and the commercial value are reduced. Shall.

  In addition, by providing the cutting rotary blade 49 and the cutting fixed blade so as to be detachable, when the onion drying operation is suspended, the foliage portion can be dug up without being cut. It becomes a high crop harvester.

  On the rear side of the left and right center of the shoulder aligner 51, a guide drive case 55 provided with a guide drive pulley 52 that rotates by receiving a driving force from the branch transmission case 6 is tilted backward and tilted up and down on the rear side. A guide driven pulley 53 is rotatably provided at the lower rear portion of the guide drive case 55, and a guide belt 54 is wound around the guide drive pulley 52 and the guide driven pulley 53 to form a guide device 56. doing.

  In addition, the guide belt 54 constituting the guide device 56 is provided with lugs (not shown) at equal intervals on the outer peripheral edge, receives the stems and leaves that are left uncut and guides the onion to the top of the onion. The foliage part and root part (beard root) shall be guided to discharge onto the ridge in a posture that does not contact the field scene.

  The stems and roots of the onion, which are guided to be discharged onto the ridge, become a posture that does not contact the farm scene, so that the root that touches the soil extends into the soil and does not leave the field with a light force during recovery. Is prevented. Further, when the root portion is extended, the nutrients of the onion are consumed, so that the quality of the onion is deteriorated, but this deterioration is also prevented.

And since the foliage part which remain | survives after cutting | disconnection does not contact the field scene, when collect | recovering an onion manually, an operator becomes easy to grasp an onion and the efficiency of a collection | recovery operation improves.
With the above configuration, cultivating onion by laying multifilm etc. on the straw, the peripheries of the hole formed at the time of transplanting work and the foliage are intertwined, and the multifilm is put together at the time of pulling and harvesting the onion The guide device 56 can contact the onion through the multi-film and guide it to the lower rear side even when it is lifted to the rear, so that the multi-films are prevented from being overly overlapped when the onion falls. The removal work of the film becomes easy and the recovery work of the onion dug up on the fence becomes easy.

  In addition, since the rear side of the guide device 56 is configured to be rotatable in the vertical direction, when the guide device 56 is unnecessary, such as when harvesting onion cultivated onion where no multi-film is laid, the guide action portion is arranged on the body frame 1 side. Therefore, the crop harvester can be adapted to various working conditions.

  As described above, since the guide device 56 can come into contact with the multi-film, it is desirable that the guide belt 54 be made of a material having a weaker frictional force such as sponge than rubber in order to prevent the multi-film from being damaged.

  The onion discharged by the guide device 56 falls onto the vegetation that has been vegetated before harvesting, and is collected after harvesting or after drying in the sun. However, since a normal onion is spherical, when it is discharged, the traveling device of a working machine such as a tractor that rolls on the cage and collects the left and right drive wheels 84L and 84R, the gauge wheel 73, and the onion is recovered. May fall into a passing groove. In addition, when a 3 or 4 onion is planted in one persimmon, when the 1st or 2nd onion is harvested, the discharged onion is the unharvested side, that is, the 3rd or 4th onion. May move to the vegetation side.

  If an onion falls in the culvert groove, the worker needs to pick up the onion in the culm before collecting or collecting the onion, which reduces work efficiency and reduces the work efficiency. There is a problem that the labor of a person increases.

  Then, the worker is unaware that the onion has fallen into the trough, and the traveling devices of the working machines such as the left and right traveling wheels 84L and 84R, the gauge wheel 73, or the tractor crush the onion and lose the commercial value. Therefore, there is a problem that the yield is reduced.

  In addition, when the onion rolls down on the unharvested side, the onion that rolls up on the side of the vertical pulling device 63, the horizontal pulling device 41, and the pulling and conveying device 20 prevents the foliage from being raised or pinched and pulled out. There is a problem in that the onion of the onion is generated and the operator needs to manually pull out the onion, which increases the labor of the operator.

Furthermore, there is a problem that the vertical pulling device 63, the horizontal pulling device 41, and the pulling and conveying device 20 come into contact with the rolling onion, damaging the onion and reducing the commercial value.
In order to solve the above problem, as shown in FIGS. 1, 3, and 5, the bowl of the onion discharged from the guide device 56 to the left and right sides of the shoulder aligning device 51 and the drawing frame 15 on the left and right sides. A first guide plate 133 is provided for guiding the upper side of the shoulder while preventing it from falling into the groove, and a second guide plate for preventing the onion from falling on the unharvested strip on the left and right sides of the shoulder aligner 51. 134 is provided.

  The first guide plate 133 and the second guide plate 134 are arranged in an inclined posture in which the left-right distance is wider toward the upper side of the machine body when viewed from the front (rear). At this time, if the distance between the left and right ends of the first guide plate 133 and the second guide plate 134 is about 200 to 300 mm, which corresponds to two standard size onions, the first guide plate 133 and the first guide plate 133 2 When two onions pass side by side in the left-right direction through the narrowest part of the guide plate 134 in the left-right direction, it is necessary to interrupt the work and eliminate the clogging by clogging the gap and not moving to the rear of the machine. No work efficiency is improved.

  The first guide plate 133 and the second guide plate 134 are each made of a material such as rubber that can be elastically deformed when a strong force is applied. At this time, the lower end portion of the second guide plate 134 is separated from the farm scene, and the lower end portion of the first guide plate 133 forms a grounding portion 133b that is brought into contact with the farm scene, more precisely, the end portion of the basket. The configuration is as follows.

  Of the first guide plate 133, the ground contact portion 133b that comes into contact with the farm scene is bent when the ground contact pressure is increased by making the thickness thinner than other locations or by making a plurality of cuts to bend easily. If it is set as the structure deform | transformed, it will prevent that the 1st guide plate 133 becomes running resistance, reduces running speed, reduces work efficiency, and the 1st guide plate 133 is damaged by contact resistance.

  The second guide plate 134 has a length in the front-rear direction from the conveyance start end of the shoulder aligning device 51 to a position rearward of the conveyance end, specifically, the arrangement position of the guide drive pulley 52 of the guide device 56. On the other hand, the first guide plate 133 has a longitudinal length extending from the conveyance start end of the shoulder aligner 51 to the lower side of the branch transmission case 6, and a bent guide portion 133 a directed to the left and right other side is provided below the branch transmission case 6. Form.

  With the above-described configuration, the onion, the cutting position of which is aligned by the shoulder aligning device 51, the foliage portion is cut by the cutting rotary blade 49, and is discharged and guided onto the ridge by the guide device 56, is the first guide plate 133 and the second guide. The plate 134 is placed on the ridge that has been vegetated before being drawn and harvested and has been harvested. As a result, the onion is prevented from rolling to the side where the trough or harvesting operation is not performed.

  Therefore, it is not necessary to collect the onion that has fallen into the trough, and the next onion harvesting operation or the recovery of the onion on the reed can be performed when necessary. The labor spent by the person is reduced.

  And since there is no onion in the culvert groove, the left and right drive wheels 84L and 84R, the gauge wheel 73, or the traveling device of the work machine such as a tractor does not step on the onion, and the yield of onion can be reduced. Is prevented.

  Further, since the onion can be prevented from rolling to the side where the harvesting operation is not performed, the onion drawing and harvesting operation of the onion by the vertical pulling device 63, the horizontal pulling device 41, and the pulling and conveying device 20 is not hindered, and the work efficiency is improved. Will improve.

  Furthermore, since the vertical pulling device 63, the horizontal pulling device 41, and the pulling / conveying device 20 can be prevented from hitting or squeezing the rolled onion, the commercial value of the onion is maintained.

  Then, since the vertical length of the first guide plate 133 is such that the lower end of the first guide plate 133 is in contact with the heel, there is no gap in which the small onion moves to the heel groove, and the onion may fall into the ridge groove. It is surely prevented.

  Further, the front-rear length of the first guide plate 133 is set such that the rear end portion of the first guide plate 133 is positioned below the branch transmission case 6, so that the guide device 56 can be operated even when the machine body is traveling forward. The first guide plate 133 receives the onion that is discharged from the roll and rolls backward, so that it can be prevented from falling into the trough groove, eliminating the need for picking up the onion, reducing the labor of the worker, and improving the work efficiency. Therefore, it is possible to prevent the yield from decreasing.

  Furthermore, by forming a bending guide part 133a toward the left and right other side at the rear end part of the first guide plate 133, and by setting the rear end part of the second guide plate 134 to the upper side in the conveying direction of the guide device 56, When large sized onions are lined up, the onion can move laterally from the rear end of the second guide plate 134, so that the onion is clogged between the first guide plate 133 and the second guide plate 134. Is prevented.

Thereby, the onion is dragged and can be prevented from being damaged by the frictional resistance with the field scene, so that the commercial value of the onion is maintained.
In addition, since the onions discharged on the basket are less likely to be densely packed, the period required for drying is shortened because the ventilation and sunlight are improved when drying in the sun.

A technique for further improving the action and effect produced by the above configuration will be described.
As shown in FIGS. 9 to 11, a guide rocking rod 135 is provided on the rocking eccentric cam 101 a constituting the rocking rod 101 in the rear direction of the machine body, and the guide rocking rod 135 on the rear side of the machine body is provided. A pivot rod 136 is provided at the end, and a fulcrum pin 137 serving as a pivot fulcrum is inserted in the vicinity of the middle portion of the pivot rod 136 in the vertical direction. The fulcrum pin 137 is fixed to the inner side of the machine body of the right traveling transmission case 80. As a result, when the swing eccentric cam 101a rotates and the guide swing rod 135 swings in the front-rear direction, the pivot rod 136 becomes the fulcrum pin. It becomes a structure which rotates in the front-back direction using 137 as a rotation fulcrum.

  Then, as shown in FIGS. 11 and 12, the lower side of the rotating rod 136 is bent toward the left and right sides of the machine body to form a swinging bent portion 136a. A plurality of mounting holes 136b... Are formed at predetermined intervals in the vertical direction in the swinging bent portion 136a, and the pivot rod 136 is rotated forward and backward at a position where the mounting holes 136b are formed. One or a plurality of striking rollers 138a for striking one guide plate 133 from the left and right sides of the machine body are attached. The striking roller 138a is formed with mounting holes 138b having the same diameter as the mounting holes 136b, and fixing members (not shown) such as bolts and nuts are passed through the mounting holes 136b and mounting holes 138b. The striking bodies 138... Are mounted.

  At this time, the striking roller 138a is positioned on the side of the bending guide portion 133a formed on the rear end portion side of the first guide plate 133, and the front and rear rotation range of the rotating rod 136 is the front and rear of the bending guide portion 133a. The configuration fits within the width.

  If the mounting holes 138b through which the fixing member penetrates have a shape in which the fixing member can be accommodated on the inner peripheral side with respect to the outer peripheral edge of the striking roller 138a, the striking roller 138a ... comes into contact with the first guide plate 133. In addition, it is possible to prevent the shock from being disturbed by the fixing member, and it is possible to prevent the first guide plate 133 from being worn quickly and the onion to be damaged and to reduce the commercial value.

  With the above configuration, the bending guide portion 133a of the first guide plate 133 is intermittently hit with the hitting body 138 by the forward / backward rotation of the rotating rod 136, so that the bending guide portion 133a is in contact with the bending guide portion 133a. The onion can be guided to move toward the center of the heel away from the ridge groove, and the onion rolls to the rear of the first guide plate 133 and is prevented from moving to the ridge groove, and the onion that has moved to the ridge groove is picked up. Work becomes unnecessary, and improvement of work efficiency, reduction of worker's labor, and reduction of onion yield are prevented.

  Further, since the striking bodies 138 are in contact with the outside of the first guide plate 133 to apply a force for guiding the onion, it is possible to prevent the striking bodies 138 from directly contacting the onion, so that the striking force is too strong. The onion is prevented from being damaged, and the commercial value of the onion is maintained.

  A guide rocking rod 135 for rotating the rotating rod 136 back and forth is attached to a rocking eccentric cam 101a constituting the rocking rod 101, so that the ball is hit using the rocking mechanism of the rocking soiler 29. Since it is possible to secure the driving force to guide, it is not necessary to construct a separate transmission path for the driving force for hitting guidance, and a simple configuration improves maintenance and reduces the number of parts and weight. And cost reduction.

  Further, by forming a plurality of mounting holes 136b in the swinging bending portion 136a of the rotating rod 136, the hitting action height of the hitting roller 138a is selected and adjusted in accordance with conditions such as growth and variety of the onion. Or the striking roller 138a can be changed to one having a different diameter, so that the onion can be reliably moved to a position away from the ridge groove.

  Further, since a plurality of striking rollers 138a can be mounted along the plurality of mounting holes 136b, at least one striking roller 138a is brought into contact with each other even under working conditions in which the size of the onion is highly variable. As a result, it is possible to prevent the onion from moving further into the ridge and improve work efficiency.

  Alternatively, as shown in FIGS. 13 to 15, a swing plate 139 that swings in conjunction with the swing soiler 29 is detachably provided across the swing soiler 29 and the right-side traveling transmission case 80R. The first guide plate 133 is struck from the outside to the rocking plate 139, the rocking rod 101 projecting forward of the machine body, and the guide rocking rod 135 projecting rearward of the machine body, and the onion is separated from the ridge groove. That is, a plurality of striking bars 140 that are moved toward the center of the heel are provided in the vertical direction.

  As shown in FIG. 13, the rocking plate 139 has a front end portion rotatably connected to a substantially central portion in the vertical direction of the rocking solubilizer 29, and a rear end portion located on the lower rear side of the right traveling transmission case 80R. Specifically, a configuration is provided that is slidable in a space portion of a gate-shaped (U-shaped) mounting stay 141 provided below the position where the traveling drive sprocket 79 is disposed, and swings in conjunction with the swinging soluer 29. And

  The plurality of striking bars 140 are detachably attached to the swing rod 101, the guide swing rod 135, and the swing plate 139, and extend from the swing rod 101 and the guide swing rod 135 to the swing plate 139. The first portion is a straight portion 140a and is bent toward the inner side of the machine body at the connection portion with the swing plate 139, and is in contact with the first guide plate 133 that is inclined toward the inner side of the machine body toward the lower end. Let it be a hit bending part 140b.

  As shown in FIGS. 15 and 16, when the second hitting bent portion 140c is formed by further bending the vicinity of the lower end portion of the hitting bar 140 ... of the first hitting bent portion 140b to the inside of the body. Since the lower side of the guide plate 133 is intensively hit, the onion is easily guided to the center side in the left-right direction of the saddle, and the onion is prevented from moving to the saddle groove.

The plurality of striking bars 140 are provided on the inner side of the body of the swinging rod 101, the guide swinging rod 135, and the swinging plate 139.
Further, as shown in FIG. 13 and FIG. 14, the striking bar 140... Provided on the rocking rod 101 has a rocking eccentric cam 101a on one side of the shoulder aligning device 51 and from the rear side of the machine body of the cutting rotary blade 49. The striking bar 140 provided on the guide rocking rod 135 is arranged at predetermined intervals over the front, and is predetermined from the front side of the body at the rear end position of the right drive wheel 80R to the rear of the rocking eccentric cam 101a. Arrange at intervals.

  When the hitting bar 140 is composed of a hard but flexible elastic member such as wood such as bamboo, spring steel material, synthetic resin, hard rubber, etc., the hitting bar 140 will be more reliably It can be separated from the groove.

  At this time, when the hardness of the hitting bar 140 is increased toward the rear side of the aircraft, the onion is guided to the central portion in the left-right direction of the rod with a stronger force as it moves toward the rear side of the aircraft. Is further prevented.

  With the above configuration, the plurality of hitting bars 140 are provided on the swinging rod 101, the guide swinging rod 135, and the swinging plate 139, thereby increasing the chance that the first guide plate 133 is hit and hitting. Since the movement guide action position of the onion heel to the center side in the left-right direction becomes longer in the longitudinal direction of the fuselage, it is reliably prevented that the onion moves to the ridge groove, improving work efficiency and reducing labor of the operator, The reduction of yield is prevented.

  Further, a striking bar 140 is provided on the rocking plate 139, and the rocking plate 139 rocks in conjunction with the rocking of the rocking soy 29 so that the driving mechanism for rocking the rocking plate 139 is separately configured. This simplifies the configuration and reduces the number of parts, improves maintainability, reduces the weight of the fuselage, and reduces costs.

  Since the swinging plate 139 is detachably provided, when the swinging plate 139 is removed, the plurality of hitting bars 140... Are removed together. Work efficiency and maintainability are improved.

  Further, since the plurality of striking bars 140 are also detachably attached to the swing plate 139, the number of striking bars 140 can be easily increased or decreased according to the working conditions, or the striking bars 140 having different hardnesses. Since the onion can be easily exchanged, it is possible to prevent the onion from moving to the trough, thereby improving the work efficiency, reducing the labor of the worker, and preventing the decrease in the yield of onion.

  In addition, since the first hitting bent portions 140b that are bent toward the inner side of the machine body are formed on the plurality of hitting bars 140, respectively, the posture of the lower side of the plurality of hitting bars 140 ... is the mounting posture of the first guide plate 133. As the lower side of the machine body is in the inclining posture toward the inside, the striking force is reliably transmitted to the first guide plate 133, and the onion is reliably prevented from moving to the ridge groove.

  When the cutting rotary blade 49 removes the foliage of the onion by providing a plurality of hitting bars 140 at predetermined intervals from the rear side of the cutting rotary blade 49 to the swing eccentric cam 101a. Oscillation is applied to the onion, the cutting action part of the cutting rotary blade 49 is disturbed, the foliage remaining on the onion is lengthened, and the operator does not need to manually remove the remaining foliage. The labor is reduced, and the cutting position of the foliage part is lowered too much, so that the onion is damaged, and it is prevented that the commercial value is reduced or lost and the commercial value is lost.

  In addition, if the onion cuts near the boundary between the stem and leaf part and the part to be harvested, the inside will be exposed, the exposed part will become hard like skin, and the product value will decrease, or corruption will start from the exposed part, Since the commercial value is often lost, it is common to leave only the stems and leaves necessary for maintaining the quality of the onion and cut only the unnecessary parts.

  Further, by providing at predetermined intervals from the front side of the body at the rear end position of the right drive wheel 80R to the rear of the swing eccentric cam 101a, the onion is not hit near the rear end portion of the first guide plate 133. Therefore, it is possible to prevent the onion that has stopped on the reed from hitting and rolling again and moving the onion to the ditch groove or the unworked adjacent work strip, thereby improving the work efficiency and reducing the labor of the worker.

Next, the structure which blocks | interrupts the movement of an onion to the ridge groove by combining the hit | damage roller 138a ... and the hit | damage bar 140 ... is demonstrated.
As shown in FIGS. 17 to 19, the first guide plate 133 and the second guide plate 134 are supported on the outer side portion of the first guide plate 133 and the outer side portion of the second guide plate 134. A hitting bar 140 is provided to prevent the onion from moving to the trough and the planting strip on which the unharvested onion is vegetated. A plurality of hitting bars 140 are provided at intervals in the front-rear direction, and a hitting bar 140 provided on the first guide plate 133 side and a hitting bar 140 provided on the second guide plate 134 side are in the lateral direction of the body. They are not arranged on the same straight line, but are arranged at positions shifted from each other in the longitudinal direction.

  Specifically, the first guide plate 133 side, that is, the front of the first hitting bar 140R1 from the front of the right side of the aircraft and the second hitting bar 140R2 of the second from the front, the front of the left side of the aircraft. The first striking bar 140L1 from the front, the second striking bar 140R2 from the front on the first guide plate 133 side and the third striking bar 140R3 from the front, the second from the front on the second guide plate side The striking bar 140L2 is positioned continuously.

  At this time, as shown in FIGS. 17 and 19, the plurality of striking bars 140... Are not connected to the left and right swing rods 101, 101, the left and right swing soilers 29, 29, etc. Let 133 and the 2nd guide plate 134 be a fixed member which presses toward the inside of the body, respectively.

  The plurality of striking bars 140 are provided from the transport start end of the shoulder aligner 51 to the transport end, in other words, in the vicinity of the guide device 56, and in the vicinity of the rear end of the second guide plate 134. The bar 140... Is not provided, and the onion is movable behind the second guide plate 134.

  The plurality of hitting bars 140 are arranged at predetermined intervals in the front-rear direction, but about ± 2 to 5 cm in the front-rear direction so that the intervals can be adjusted according to conditions such as onion growth and variety. If it is configured to be movable, the movement of onions can be suppressed even when working in fields with different work conditions, or when the onion growth or size varies greatly, improving the harvesting work efficiency and working Reduction of labor and prevention of decrease in onion yield.

  The guide swing rod 135 is provided with a plurality of pivot rods 136 in the front-rear direction so as to be swingable by swinging the guide swing rod 135 back and forth, and the lower side of the plurality of pivot rods 136. Are mounted with one or a plurality of striking rollers 138a. The number, mounting positions, diameters, and the like of the plurality of striking rollers 138 may be different for each rotating rod 136, and the striking force of the rotating rod 136 may be changed for each position.

  In particular, the swing bending portion 136a of the rotating rod 136 disposed on the rear side of the machine body is configured to be bent inward of the aircraft at a larger angle than the swing bending portion 136a of the rotation rod 136 disposed on the front side of the body. When the hitting roller 138 is hit, the first guide plate 133 is pushed into the fuselage from the other hitting positions, and the onion is surely brought closer to the center in the left-right direction. It becomes the structure which is easy to prevent movement to.

  The plurality of rotating rods 136 provided with the striking roller 138 are provided on the rear end side of the first guide plate 133, but nothing is provided on the rear end portion of the second guide plate 134. A space in which the onion moves to the center side in the left-right direction of the basket is formed behind the plate 134.

  Further, as shown in FIGS. 17 and 19, the vertical lengths of the plurality of striking bars 140... Are made shorter than the vertical lengths of the first guide plate 133 and the second guide plate 134. Specifically, a plurality of striking bars 140... 50 mm to 100 mm from the lower ends of the first guide plate 133 and the second guide plate 134 and a length corresponding to the vertical height of one standard onion. The vertical length shall be shortened.

  The length from 50 mm to 100 mm is merely a reference value, and can be shorter or longer. For example, the striking bar 140 is composed of a plurality of plate members and fixing members such as bolts and nuts, and the length is set such that the positional relationship between the plate members is not changed by the fixing members after the assembly position of the plurality of plate members is changed. A changing configuration is mentioned.

  In addition to the above, as shown in FIGS. 17 and 19, when the impact roller 138 is mounted on the lower end of the rotating rod 136 except for the rotating rod 136 disposed at the rearmost part of the guide rocking rod 135, The lower end portion of the striking roller 138 is configured to be located about 50 mm to 100 mm above the lower end portions of the first guide plate 133 and the second guide plate 134.

  On the other hand, when the striking roller 138 is provided at the lower end of the rotating rod 136 disposed at the rearmost part of the guide rocking rod 135, the striking roller 138 is moved from the lower end of the other striking rollers 138a. Also, the first guide plate 133 and the second guide plate 134 are positioned above the lower ends of the first guide plate 133 and the second guide plate 134. The vertical position of the last hitting roller 138 at this time is about 20 mm to 40 mm from the lower ends of the first guide plate 133 and the second guide plate 134.

  With the above configuration, a plurality of striking bars that contact the first guide plate 133 and the second guide plate 134 from the outside on both the left and right sides of the shoulder aligning device 51 and keep the first guide plate 133 and the second guide plate 134 in a tension state. 140... Are provided so that the onion in the middle of shoulder alignment conveyance is not struck and the first guide plate 133 and the second guide plate 134 can push the onion back onto the heel. Is prevented, and the product value is prevented from deteriorating due to scratching of the onion.

  Also, the left and right striking bars 140 are each arranged at predetermined intervals in the longitudinal direction of the aircraft, and the left and right striking bars 140 are arranged so that they do not line up in a straight line. When this is done, the onion can be retracted by deforming the space between the left and right striking bars 140 in the front-rear direction, i.e., the non-pressed portions of the first guide plate 133 and the second guide plate 134, The onion is clogged between the first guide plate 133 and the second guide plate 134, preventing the harvesting operation from being delayed, and the work efficiency is improved.

  Further, by providing the rotating rod 136 with the striking roller 138 only on the rear side of the first guide plate 133, that is, in the vicinity of the discharge position of the guide device 56, the rear side of the body remains in contact with the first guide plate 133. Since the onion that has moved to the vicinity can be reliably moved to the center in the left-right direction of the kite, the onion is prevented from moving from the rear end portion of the first guide plate 133 to the kite groove and moved to the kite groove. The work of picking up the onion is no longer necessary, improving the work efficiency, reducing the labor of the worker, preventing the onion from being crushed and reducing the yield.

  Further, the lower end of the hitting bar 140 and the lower end of the hitting roller 138a other than the rearmost part are located above the lower ends of the first guide plate 133 and the second guide plate 134, and are separated from the field scene. Thus, the hitting bar 140 ... and the hitting roller 138a ... can be prevented from being damaged by the resistance when coming into contact with the farm scene, so that the durability is improved and the hitting groove of the onion is prevented from moving, The work efficiency can be improved and the labor of workers can be reduced.

  In addition to this, the striking bar 140 ... and the striking roller 138a ... collapse the heel end portion close to the field scene, especially the onion planted on the outermost side, and create a space between the first guide plate 133 and the heel end portion. Since the onion can be prevented from moving to the trough groove, the work efficiency can be improved, the labor of the worker can be reduced, and the onion yield can be prevented from decreasing.

  Further, since the position where the hitting roller 138a hits the first guide plate 133 hits the upper side of the onion located inside the first guide plate 133, it is possible to prevent a strong hitting force from being applied to the onion, It prevents the onion from being damaged and the product value from being lowered.

  On the other hand, since the last hitting roller 138 is positioned below the hitting bar 140 and the other hitting rollers 138a, a strong hitting force can be applied to the onion via the first guide plate 133. The onions that are likely to fall into the trough can be kept on the trough, eliminating the need to collect the onions that have moved to the trough, improving the work efficiency, reducing the labor of the workers, and crushing the onions It is possible to prevent the amount from decreasing.

  And, as shown in the figure, the second branch transmission case 6a is provided on the left and right other sides of the branch transmission case 6, and the output shaft 57 is raised from the front of the second branch transmission case 6a toward the front of the machine body, A bevel case 58 a that changes the driving force from the left and right other sides to the left and right sides is attached to the front end of the raised output shaft 57. A pair of bevel gears (not shown) are housed inside the bevel case 58a, and the driving force of the pulling output shaft 57 in the output case is vertically lifted and transmitted to the transmission shaft 58 via the pair of bevel gears. To do. Then, the longitudinally driven drive pulleys 59, 59, 59 are respectively attached to the longitudinally raised transmission shaft 58 at the left and right one side ends, the left and right other side ends and the substantially central portion in the left and right direction, and the longitudinally driven drive pulleys are mounted. A vertically raised cover 60, 60, 60 that covers both the left and right sides of 59, 59, 59 is mounted in a rear-up tilted posture and freely rotatable up and down. Further, the longitudinally driven covers 60, 60, 60 are respectively provided with longitudinally driven pulleys 61, 61, 61 at the lower end portions thereof, and the longitudinally driven driving pulleys 59, 59, 59 and the vertically driven driven pulleys 61, 61 are provided. , 61 is wound around longitudinally erecting belts 62, 62, 62 provided with a plurality of vertically elevating lugs 62a...

  It should be noted that the rearward tilt angle of the vertical pulling device 63 is substantially the same as the rearward tilt angle of the horizontal pulling device 41. As a result, the foliage portion caused by the vertical pulling device 63 is pulled up vertically and is laterally raised at a timing away from the lugs 62a, so that it is taken over by the horizontal pulling lugs 39a of the device 41. 20 can be guided to the conveyance start end portion, and the onion harvesting efficiency can be improved.

  Further, a gauge wheel elevating case 70 is provided at one end of the longitudinally raised transmission shaft 58 on the left and right sides, a hollow upper arm 71 is provided below the gauge wheel elevating case 70, and a gauge is provided in the hollow portion of the upper arm 71. A lower arm 72 for rotatably mounting the ring 73 is provided so as to be movable up and down. In addition, upper and lower ends of the pantograph mechanism 74 are provided on the upper arm 71 and the lower arm 72, respectively, and a fixed plate 75 is provided on the drive case 4. A turnbuckle 76 capable of adjusting the longitudinal length is provided between the fixed plate 75 and the rear portion of the gauge wheel lifting case 70, and the turnbuckle 76 is extended or contracted to move the lower arm 72 up and down. A wheel adjustment handle 77 is provided.

  With the above-described configuration, the vertical pulling device 63 and the horizontal pulling device 41 are surely connected to the onion by causing the stems and leaves of the onion hanging in the trough to fall before the gauge ring 73 steps. Since the stems and leaves can be caused, the caused stems and leaves can be pinched by the pulling / conveying device 20 and pulled out from the soil, so that the operator does not need to manually pull out the onion left behind. The effort is reduced.

  In addition, even if the shoots and leaves of the onion on the harvesting basket hang down and entangled in the trough, the shoots on the adjacent strips can be unraveled by lifting the shoots together. And the onion can be reliably pulled out by the pulling and conveying device 20.

  Then, by operating the gauge wheel adjusting handle 77 to raise or lower the lower arm 72 provided with the gauge wheel 73, the working position of the lateral pulling device 41 and the pulling / conveying device 20 can be changed according to the growth state of the onion and the height of the straw. Since it can be changed according to the height, the foliage part is pulled up and pulled out reliably, and the work efficiency is improved.

Another example of the configuration of the above-described mechanism for restricting the movement of the onion to the trough and the unharvested working strip is shown below.
As shown in FIGS. 20 and 21, a swing relay rod 142 in the vertical direction is provided on the inner side of the swing rod 101 on the left and right sides of the body, and a pair of left and right link rods 143 are provided below the swing relay rod 142. 143 is detachably provided in the front-rear direction. In particular, the left and right link rods are provided directly below the swing rod 101. The left and right link rods 143 and 143 are provided with guide paddles 144 for restricting the movement of the onion into the eaves groove and moving the onion from the outside of the first guide plate 133 to move the eave to the center in the left-right direction. It can be pivoted.

  As shown in FIG. 22, a plurality of the guide paddles 144 are provided at predetermined intervals in the front-rear direction, and rotate in conjunction with the front-rear swing of the link rod 143 on the inner side of the fuselage among the left and right link rods 143, 143. In a plan view, it is configured to switch between a linear posture in the front-rear direction and an inclined posture located on the rear side of the aircraft toward the other left and right sides of the aircraft.

  Further, the guide paddle 144 is configured such that the side surface of the body, that is, the surface that strikes the ball over the first guide plate 133 is covered with a soft member such as rubber or vinyl chloride, or the entire guide paddle 144 is hard rubber. It is comprised with the elastic member which is comparatively hard and elastic.

  Then, the second guide plate 134 is pressed from the outside of the body, and a pressing paddle 145 is provided on the other left and right sides of the body so that the rear side of the second guide plate 134 is positioned inside the body. The pressing paddle 145 is configured so that an inclination angle from the outer side of the machine body to the inner side of the machine body can be adjusted by a pulling member (not shown) such as a push bolt, and the onion leaning on the second guide plate 134 side is arranged on the outer side of the machine body. It is set as the structure guided to the position which approached.

  With the above configuration, since the power for rotating the guide paddles 144 can be obtained by using the swing mechanism of the swing soiler 29, the left and right link rods 143 and 143 including the guide paddles 144 are swung back and forth. It is not necessary to separately configure the transmission path to be performed, the transmission path is simplified, the maintainability is improved, and the weight of the machine body and the cost are reduced by reducing the number of parts.

  Further, since the plurality of guide paddles 144 intermittently strike the first guide plate 133, the entire first guide plate 133 can guide the onion to the left and right center side of the reed, so that the onion is in the reed groove. It is prevented from moving, improving work efficiency, reducing the labor of workers, and preventing the onion yield from decreasing.

  In the working condition where the onion guide can be guided only by the first guide plate 133 and the second guide plate 134 by detachably attaching the left and right link rods 143 and 143 to the relay swing rod 142, It is no longer necessary to apply a striking force, and the onion is prevented from being damaged by striking, and the commercial value of the onion is improved. In addition, there is no need to put unnecessary loads on the aircraft, and durability is improved.

  Further, by providing a soft member on the striking surface side of the guide paddle 144 or configuring the guide paddle 144 with an elastic member, it is difficult to apply excessive striking force to the onion, so that the onion is less likely to be damaged, and the onion product Value is improved.

  Then, by configuring the angle of the pressing paddle 145 that presses the second guide plate 134 from the outside, it is possible to freely change the vicinity of the onion on which the second guide plate 134 brings the onion. Therefore, in the work of harvesting onions at the same time, it is possible to prevent the onions from moving too close to each other, prevent them from colliding and getting damaged, and drying by sunlight and wind is efficient. As a result, the product value of onions is improved.

  In the above configuration, when the left and right link rods 143 and 143 swing back and forth as the swing rod 101 swings back and forth, the plurality of guide paddles 144 are all rotated at the same timing. If the paddles 144 ... strike the first guide plate 133 at the same time, the interval until the next strike is increased, and the onion moves from the rear end portion of the first guide plate 133 to the ridge groove without being hit. There is a fear.

  Therefore, when the guide paddles 144 are formed with a long hole portion 144a in the front-rear direction, and the guide paddles 144 are attached to the link rod 143 on the left and right sides of the machine body or on the left and right sides of the body, It is located inside the part 144a. The long hole portion 144a has a shorter front-rear length as it is formed on the guide paddle 144 on the front side of the machine body, and a longer front-rear length as it is formed on the rear side of the machine body.

  Accordingly, when the side of the link rod 143 on which the rotation mounting pin 145 is inserted into the long hole portion 144a and the guide paddles 144 are attached moves forward, the rear end portion of the long hole portion 144a is turned to the rotation mounting pin 145. The guide paddles 144 are changed from a straight posture to an inclined posture toward the inner side of the aircraft from the position in contact with the plurality of guide paddles 144. The plurality of guide paddles 144 hit the first guide plate 133 step by step, so that the number of hitting opportunities increases. This makes it easier to guide the onion to the center side in the left-right direction of the basket.

  When the link rod 143 moves rearward, the guide paddles 144... Change from the inclined posture toward the inside of the machine body to the linear posture from the position where the front end portion of the long hole portion 144 a contacts the rotation mounting pin 145. It becomes.

  In addition, a bent portion toward the inner side of the machine body is formed on the lower side of the guide paddles 144... With this configuration, the hitting guide trajectory of the guide paddles 144 may be set as the flip-up direction.

In order to realize the above configuration example with a simple configuration, the following configuration may be adopted.
As shown in FIGS. 23 and 24, a pressing protrusion 146 is provided at the lower end of the relay rocking rod 142, and the onion is placed below the pressing protrusion 146 via the first guide plate 133 toward the center in the left-right direction of the basket. A striking plate 147 for guiding the striking, and a pivot shaft 148 in the front-rear direction for pivoting the striking plate 147 in the left-right direction of the machine body, that is, in the rolling direction, are provided.

  The rotation support shaft 148 is provided with a non-circular cam 149, and the rotation support shaft 148 rotates through the cam 149. The cam 149 is provided with an urging member (not shown) such as a torque spring that rotates when pressed by the pressing protrusion 146 and returns to the original position when the pressing force is weakened.

  The striking plate 147 has a left-right striking portion 147b that strikes the first guide plate 133 through an inclined portion 147a facing the inner side of the airframe toward the rear side of the airframe, facing the rear end of the cutting rotary blade 49. The structure is a trapezoid in plan view. However, this description does not constrain the shape of the striking plate 147.

  In the above configuration, when the relay swing rod 142 swings forward, the pressing projection 146 descends and comes into contact with the cam 149, the cam 149 is pressed and rotated, and the striking plate 147 rotates toward the inside of the machine body. The first guide plate 133 is hit. Then, when the relay rod 142 swings backward and the pressing projection 146 rises and separates from the cam 149, the cam 149 returns to its original position by the biasing member, so that the striking plate 147 rotates toward the outside of the machine body. A configuration that fits in a substantially vertical position with respect to the farm scene.

  By adopting the above-described configuration, the onion having the stem and leaf portion cut can be hit and guided by the hitting plate 147 via the first guide plate 133, and can be reliably guided to the center side in the left-right direction of the straw. It is prevented from moving to the trough, and the work efficiency is improved, the labor of the worker is reduced, and the onion yield is prevented from being reduced.

  Further, by providing the rotation support shaft 148 below the relay swinging rod 142, that is, at a position away from the drawing / conveying action area of the drawing / conveying device 20, the rotation trajectory of the striking plate 147, particularly the left and right sides of the rod when returning. Since the onion close to the center in the direction is less likely to be located on the trajectory, the onion is prevented from being damaged and the commercial value is improved.

Next, the structure of the traveling transmission system of this machine is shown.
As shown in FIGS. 1 to 3, a right output shaft 78R is provided on one of the left and right sides of the drive case 4, and a travel drive sprocket 79 is attached to the right output shaft 78. The travel drive sprocket 79 is attached to the right travel transmission case 80R. The interior is on the top side. Then, the right traveling transmission case 80R is in a rear-upward inclined posture, and a traveling driven sprocket 81 is rotatably mounted on the lower end side of the right traveling transmission case 80R located on the front side of the aircraft, and the traveling driving sprocket 79 and the traveling driven sprocket 81 are provided. The travel transmission chain 82 is wound around.

  A tension sprocket may be provided in the winding region of the travel transmission chain 82, or a clutch mechanism may be provided that prevents the breakage by retracting from the travel transmission chain 82 to stop driving when a load is applied.

  Further, an axle 83 is mounted on the traveling driven sprocket 81, and a right drive wheel 84R is provided on the axle 83. Further, left and right support plates 85 are provided at the rear upper end of the right traveling transmission case 80R, and the adjustment rod 86 is rotatable between the left and right support plates 85 and 85 and the rear portion of the upper frame 71. A swing adjusting handle 87 is provided for changing the rearward tilt angle of the right traveling case 80R by rotating the adjusting rod 86. An upper frame 71 is attached to the front end portion of the adjustment rod 86 so as to be rotatable forward and backward.

  According to the above configuration, when the tilt angle of the right driving wheel 84R is changed by operating the swing adjustment handle 87 to change the rearward rising inclination angle of the right traveling transmission case 80R, the work is performed on a field where the slope or the heel has collapsed. When changing the position, the vertical position of the right drive wheel 84R can be changed so that the aircraft can be placed in a substantially horizontal posture with respect to the field scene, so that the stems and leaves of the onion and the onion are pulled out reliably. The operator does not need to manually pull out the remaining onion, and the labor of the operator is reduced.

  Further, since the upper frame 71 is mounted on the front end of the adjustment rod 86 so as to be rotatable up and down, when the swing adjustment handle 87 is operated to rotate the right traveling case 80R up and down, the upper frame 71 is interlocked and moved back and forth. Since it rotates, the ground contact height of the gauge wheel 73 can be changed in conjunction with the vertical position of the right drive wheel 84R, the adjustment work can be easily performed, and the raising height of the foliage part of the vertical pulling device 63 is raised. Since the height is automatically adjusted to an appropriate position, the drawing and conveying work is efficiently performed.

  On the other hand, as shown in FIGS. 2 and 3, a left output shaft 78L is slidably provided in the left and right other ends of the second branch transmission case 6a on the left and right other sides of the machine body. A mounting plate 88 is provided at the rear, and the mounting plate 88 and the drive case 4 support the fixed side 89 a of the tread adjusting cylinder 89. Then, a travel drive sprocket 79 is mounted on the left output shaft 78L, and the travel drive sprocket 79 is installed in the upper part of the left travel transmission case 80L. Further, the left traveling transmission case 80L is in a rear-upward inclined posture, and a traveling driven sprocket 81 is rotatably mounted on the lower end side of the left traveling transmission case 80L located on the front side of the aircraft, and the traveling driving sprocket 79 and the traveling driven sprocket 81 are provided. The travel transmission chain 82 is wound around. Further, an axle 83 is mounted on the traveling driven sprocket 81, and left driving wheels 84L are provided on the axle 83.

  When the moving side 89b of the tread adjusting cylinder 89 is connected to the upper end portion of the left traveling transmission case 80L, and the tread adjusting cylinder 89 is extended, the moving portion 89b and the left transmission shaft 78L move in the left and right directions. The left traveling transmission case 80L is separated from the body frame 1, and the right and left distance between the right driving wheel 84R and the left driving wheel 84L is increased. On the other hand, when the tread adjusting cylinder 89 is contracted, the moving portion 89b and the left transmission shaft 78L move in the left-right direction so that the left traveling transmission case 80L approaches the body frame 1 and the right drive wheel 84R and the left The left and right intervals of the drive wheels 84L are configured to be narrow.

  With the above configuration, the left and right drive wheels 84L can be changed in left and right positions according to the left and right width of the rod. Therefore, it is necessary to move the left drive wheels 84L on the rod when working in a field with different left and right widths of the rod. The onion can be extracted and harvested in a stable posture, improving work efficiency.

  Further, when loading the airframe onto a loading platform such as a light truck or storing it in a warehouse or the like, the left-right distance between the left and right drive wheels 84L, 84R can be reduced to the limit, thereby reducing the left-right width of the airframe. As a result, loading and storage of the aircraft can be performed efficiently.

  In addition, if the wheel cover which prevents the stem and leaf part of the onion hanging from the adjacent strip from being entangled with the spoke or the axle 83 is detachably provided on the inner peripheral portion of the right drive wheel 84R, the stem and leaf part is entangled and adjacent It is prevented that the onion of the strip is pulled out and cannot be drawn and harvested by the drawing / conveying device 20, and the work efficiency is improved.

  The onion planted in the soil is located at a certain depth depending on the setting at the time of transplanting the seedling, but the height of the cocoon varies depending on the formation work and the subsequent wind and rain, etc. If the vertical height of 29 is not changed, there may be some problems such as the soil cannot be sufficiently solved and many roots remain.

  In order to prevent the above problem, as shown in FIGS. 25 and 26, the vertical position of the rocking soy 29 is detected at the front of the machine body of the vertical adjustment arm 111 and behind the bifurcated branching support 111a. A detection rotation arm 114 provided with a potentiometer 113 is provided, and a grounding rotator 116 that contacts the field is provided below a horizontal rotation shaft 115 that is a rotation fulcrum of the detection rotation arm 114. The grounding rotator 116 includes a roller 116a that rotates due to grounding resistance, and a spring 116b that moves the roller 116a up and down to rotate the detection turning arm 114 up and down when the roller 116a passes through the unevenness of the field. However, the unevenness of the fine field is ignored by the spring 116b, and the unevenness of the large field is configured to prevent damage due to excessive resistance due to expansion and contraction of the spring 116b.

  When the rotation angle of the rotation detection arm 114 detected by the potentiometer 113 changes, the vertical adjustment cylinder 109 expands or contracts in accordance with the change amount of the angle, and the vertical adjustment arm 111 rotates up and down to swing the rocking soiler. The vertical position of 29 is finely adjusted.

  A vertical height marker 117 indicating the vertical position of the oscillating sour 29 is provided on the upper part of the rotary plate 103, and the height of the soyer is set above the rotary shaft 115 of the rotary detection arm 114. In addition to supporting the posture of the height marker 117, an indicator 118 indicating the reference height from the farm scene is provided in the vertical direction. The indicator 118 has an L shape in which a bent portion 118a is formed at the upper end portion in front of the machine body in a side view, and a U-shaped space portion is formed in the bent portion 118a. The upper side of the height marker 117 is exposed. A plurality of scales are provided on the upper side of the soiler height marker 117, and the operator reads the working depth of the rocking soy 29 from the length protruding from the upper end of the indicator 118.

  Further, a long hole 119 in the vertical direction is formed on the upper end side of the indicator 118, and at least two depth detection sensors 120d and 120s are provided in the long hole 119. The depth detection sensors 120 d and 120 s are constituted by photoelectric sensors or proximity sensors, and are provided on the front side of the indicator 118 so as to be movable in the vertical direction along the long hole 119, and the depth on the rear side of the indicator 118. A fixing member such as a butterfly bolt that restricts the movement of the detection sensors 120d and 120s is provided, and the vertical positions of the detection sensors are arranged to be adjustable.

  Note that one depth detection sensor 120d detects that the working height of the swinging sour 29 is on the “deep” side, and the other depth detection sensor 120s is that the working height of the swinging sour 29 is “shallow”. Therefore, if a partition plate for restricting the vertical movement range of the depth detection sensors 120d and 120s is provided in the long hole 119, the detection position can be easily set.

  In the above description, the two depth detection sensors 120d and 120s detect “shallow” and “deep”, but three or more depth detection sensors may be provided to detect the depth more finely. .

  Then, on the front side of the indicator 118 and below the bent portion 118 a, a detected ring 121 in which the depth detection sensors 120 d and 120 s recognize the depth of the swinging soiler 29 is attached to the soiler height marker 117. When one of the depth detection sensors 120d and 120s detects the detected ring 121 during the onion drawing harvesting operation, the vertical adjustment cylinder 109 is expanded or contracted by a predetermined amount, and the vertical adjustment arm 111 is moved upward or downward. , And the vertical position of the rocking soiler 29 is adjusted.

  When traveling is stopped, or when the drawing / conveying device 20 and the vertical pulling device 63 are stopped, the vertical adjustment cylinder is detected even if the depth detection sensors 120d and 120s detect the detected ring 121. 109 is configured not to expand and contract. The above determination is made based on the operation positions of the travel operation lever 10 and the work operation lever 11.

  The soira height marker 117 is made of a flexible metal such as a wire coated with a resin such as vinyl chloride, or an elastic material made of rubber, synthetic resin, or the like. It is set as the structure which can prevent both damage by bending. Further, the upper end of the soira height marker 117 is lit or flashed when either of the depth detection sensors 120d and 120s is in a detection state, and visually notifies the operator of the detection. A detection lamp 122 such as an LED is provided.

  The lighting and flashing of the detection lamp 122 also operates when the potentiometer 113 that detects the rotation angle of the detection rotation arm 114 detects a change in the rotation angle and expands and contracts the vertical adjustment cylinder 109. Shall. At this time, if the detection lamps 122 are provided in two upper and lower stages, the upper stage lights up when the depth detection sensors 120d and 120s are detected by the detected ring 122, and the lower stage lights up when an angle change of the potentiometer 113 is detected. It becomes easy for a person to grasp which height control is performed. Alternatively, the blinking pattern of one detection lamp 122 may be different.

  The detection lamp 122 may be energized by a method using a wire constituting the soiler height marker 117 in addition to a method of arranging a cable along the solitary height marker 117. At this time, the wire is provided with a coating or cover made of a highly insulating rubber or synthetic resin so that the energized portion is not exposed.

  With the above configuration, when the vertical adjustment cylinder 109 is expanded and contracted to change the vertical position of the rocking soy 29, the operator grasps how much the operator moves up and down while looking at the positional relationship between the indicator 118 and the height marker 117 of the soy. As a result, it is easy to adjust the working height of the rocking soiler 29, to make sure that the soil around the onion is unraveled and to make it easy to extract and harvest, and the root of the onion is easy to be cut, and after harvesting. This reduces the time and effort required for the preparation.

  When the angle of the rotation detection arm 114 detected by the potentiometer 113 is changed due to unevenness when the grounding rotating body 116 is brought into contact with the farm field, the vertical adjustment cylinder 109 expands and contracts and the vertical position of the rocking sour 29 is changed minutely. By doing so, the operating position of the swing soiler 29 due to the unevenness of the field can be adjusted to an appropriate position, so that the swing soiler 29 is prevented from contacting the onion and damaging the onion, and the commercial value of the onion is reduced. Is prevented.

On the other hand, since the rocking soy 29 can be prevented from moving too far downward from the onion, the root of the whisker is easily cut during the harvesting operation, and the time and labor required for the preparation operation after the harvesting are reduced.
Further, when there is a large unevenness such that either one of the depth detection sensors 120d and 120s detects the detected ring 121, the depth detection sensors 120d and 120s detect the detected ring 121 and at the same time, adjust the vertical adjustment cylinder 109. Since the working height of the swinging soiler 29 can be moved to the “shallow” side or the “deep” side, the working height can be increased even in a situation where a significant change in the working height of the swinging sour 29 is required. Can be automatically adjusted to an appropriate position, so that it is possible to prevent the onion from being damaged and reduce the commercial value, and to facilitate the post-harvest preparation.

  When the depth detection sensors 120d and 120s are in the detection state, the vertical adjustment cylinder 109 is expanded and contracted in preference to the operation of the vertical adjustment cylinder 109 due to the angle change of the rotation detection arm 114 detected by the potentiometer 113. The configuration.

  Further, when the depth detection sensors 120d and 120s are in the detection state, the detection lamp 122 is turned on or blinks so that the operator can visually recognize the detection state, so that the operator can automatically move the vertical position of the rocking sour 29. The pulling and harvesting work can be done by grasping that it is adjusted, so there is no need to operate the vertical adjustment lever at unnecessary timing, and the work efficiency is improved.

  In the above, the shape of the rocking soiler 29 is L-shaped when viewed from the front. However, as shown in FIG. 27, the vertical mounting portion 29z attached to the sora support arm 105 and the lower part of the onion enter to unravel the soil. At the same time, a bent portion 29x having a V-shape in front view is formed between the action portions 29y in the left-right direction for removing the root of the hair.

  The bent portion 29x includes a vertically inclined portion 29w that is inclined 20 to 30 degrees from the mounting portion 29z toward the other left and right sides of the machine body, and a left and right end portion of the action part 29y from the lower end portion of the vertically inclined part 29w. Left and right inclined portion 29v inclined upward. The above-described shape is formed by bending the swinging soiler 29.

  Further, in order to make the swinging solubilizer 29 easily bite into the soil, the swinging sour 29 is configured to retreat about 5 degrees from the outer end of the body toward the inner end of the body in plan view. The receding angle is formed with the end facing the rear side of the machine body in a plan view when the left and right inclined portions 29v are formed.

  Furthermore, when forming the up-and-down inclined portion 29w, the base portion side of the rocking soiler 29 enters the soil in advance by bending the end portion of the up-and-down inclined portion 29w toward the front side of the machine body. .

  With the above configuration, the boundary between the up-and-down inclined portion 29w and the left-right inclined portion 29v of the swinging soluer 29, that is, the bent portion 29x precedes the portion and enters the dredger, and the action portion 29y moves in the dredged soil in a backward posture. Therefore, the lowering of the unraveling action and the root cutting action of the rocking soy 29 due to the resistance of the soil is prevented, the work efficiency is improved, and the time and labor required for the post-harvest preparation work are reduced.

  Moreover, since the rocking soiler 29 can be made to enter from the lower part of the side surface of the fence, the soil can be unwound from the lower side of the laid multi-film, and therefore the work of collecting the multi-film after excavating the onion from the field Can be performed, and work compatibility is widened.
