JP 2009-22224 A (paragraph "0042", see FIG. 2)

In Patent Document 1, an underground stem crop that has been pulled out and conveyed backward is separated from the leaf stem portion by a cutting device and dropped, and the underground stem crop is conveyed to one horizontal side and prepared for one horizontal side of a traveling machine body. A structure for recovering to a receiving portion storage container on a mounting plate is shown. In this structure, the rhizome crops are collected in a receiving storage container placed on a mounting plate, and when the container is full, the position of the full container is shifted forward, and an empty container is prepared separately to store the next crop. Harvesting operations are carried out so as to receive rhizome crops.
For this reason, the work of collecting rhizome crops in individual receiving storage containers on the mounting plate, the work of moving full containers forward and replacing them with empty containers, and the work of moving many receiving storage containers from the mounting plate. work such as unloading is required. Therefore, it is necessary to stop traveling of the machine body for each work, which tends to lead to loss of operation time of the crop harvester. Moreover, there is a problem that a great amount of working time and labor is required for the operator.

An object of the present invention is to provide a crop harvester that can easily and efficiently collect crops by reducing the labor of harvesting crops and the loss of operation time of the crop harvester.

The crop harvesting machine of the present invention is characterized by a rearward conveying device that grasps the stem portion of the crop to be harvested and conveys it backward, and a dropping that treats the crop fed from the rearward conveying device so as to drop from the stem portion. A processing apparatus, a relay conveying apparatus for placing and conveying an object to be processed after drop-off processing in one direction, and a collecting apparatus for storing the object to be processed transferred from the conveying end side of the relay conveying apparatus. A crop harvester provided on a traveling machine body, wherein the recovery device has a recovery start point at which the material to be processed is transferred from the relay conveying device, and a terminal end position horizontally separated from the recovery start point; and the bottom surface of the storage portion is configured by a conveyor capable of transporting the objects to be processed in the longitudinal direction of the storage portion, and the conveyor of the recovery device moves toward the rear side of the machine body. A cover member that can be opened and closed is provided at an open/close opening at an end position in the conveying direction, and a locked state that maintains the cover member in a closed posture and an unlocked state that allows the cover member to be opened are provided on the rear surface side of the cover member. an electric motor for driving the conveyor; a control device for controlling the electric motor; a sensor for detecting the object to be processed conveyed by the relay conveying device; A full sensor provided at the front end of the interior of the container and capable of contacting the object to be processed, and a full sensor disposed behind the lid member near the opening and closing portion to direct the object to be processed by the conveyor to the side of the opening and closing portion. and a manual operation switch that enables driving in the direction of conveying by pressing and stopping the driving, and the control device operates the electric motor in the positive direction for a certain period of time when the sensor detects the object to be processed. Thus, the conveyor conveys the objects to be processed forward, an alarm is issued when the full sensor detects the existence of the objects to be processed, and the manual operation is performed in a situation where the lock operation tool is in the unlocked state. A switch operation causes the conveyor to operate in the opposite direction, thereby enabling the object to be processed to be discharged from the opening/closing portion.

According to the present invention, the collecting device for storing the objects to be processed transferred from the transfer terminal side of the relay conveying device has a collection starting point where the objects to be processed are transferred from the relay conveying device, and a horizontal recovery point from the collecting starting point. The container has an elongated storage portion extending to end positions separated in a direction, and the bottom surface of the storage portion is configured by a conveyor capable of conveying the workpiece in the longitudinal direction of the storage portion. Therefore, the object to be processed transferred from the transfer terminal side of the relay conveying device does not stay at the collection start point where the object to be processed is transferred, but is conveyed toward the terminal position away from the collection start point in the horizontal direction. will be
Therefore, it is not necessary to collect the material to be processed while exchanging the containers one after another at the collection start point, and it is not necessary to stop the harvesting machine each time the container is exchanged at the collection start point.
As a result, the operating efficiency of the harvesting machine can be improved, and the work of collecting the material to be processed while exchanging the container on the traveling machine becomes unnecessary, which is advantageous in that the work time and labor for collecting the crops can be saved. be. In addition, it is useful in that it is easy to reduce the loss of crops, such as the material to be processed spilling every time the container is replaced.

In the above configuration, the storage unit is configured separately from the conveyor and has a vertical wall portion projecting upward from the upper surface of the conveyor, and the vertical wall portion is configured to convey the object to be processed on the conveyor. It is preferably fixedly installed at both laterally outer positions of the upper surface along the direction.

According to this configuration, since the vertical wall portions that protrude upward from the upper surface of the conveyor are fixedly installed at both laterally outer positions of the upper surface of the conveyor along the conveying direction of the object to be processed, the upper surface of the conveyor has a large amount of space. The object to be processed can be transported in a state where the object to be processed is placed.
This makes it possible to increase the volume of the entire storage section and lengthen the continuous operation time of the harvesting machine as compared with the case where the vertical wall portion protruding upward from the upper surface of the conveyor is not provided.

In the above configuration, the recovery start point of the recovery device is located at a location facing the transfer end portion of the relay carrier device, and the object to be processed is transported in a direction intersecting the conveying direction of the object to be processed by the relay carrier device. It is preferable that the transport direction of the object to be processed in the collecting device that transports the object is along the front-rear direction of the traveling machine body.

According to this configuration, it is easy to ensure that the length of the recovery device in the object-to-be-processed conveying direction is as long as possible, and that the volume of the recovery device is large.

In the above configuration, the conveyor has its operation timing set in the object conveying direction so that each time the sensor detects the object, the object is intermittently fed in the forward direction by a predetermined amount . It is preferable to have

According to this configuration, it is easy to avoid the accumulation of a large amount of the material to be processed at the recovery start point of the recovery device, and to reduce the possibility that the material to be processed falls out of the recovery device.

In the above configuration, it is preferable that the collection device is provided with an opening and closing opening from which the object to be processed can be taken out on one end side of the conveyer in the direction in which the object to be processed is conveyed.

According to this configuration, the open/close opening from which the object to be processed can be taken out is provided on one end side in the conveying direction of the object to be processed. easy to take out.

In the above configuration, it is preferable that the conveyer is configured so that the conveying direction of the object to be processed can be changed between the forward direction toward the end position separated in the horizontal direction from the collection start point and the reverse direction. .

According to this configuration, even if the open/close opening from which the object to be processed can be taken out is provided only on one end side near the recovery start point in the object conveying direction, by driving the conveyor in the opposite direction, the horizontal The object to be processed, which has been transported to the end position away in the direction, can be transported back to the recovery start point side in the opposite direction, and can be taken out from the open/close port on the one end side.

In the above configuration, the opening and closing portion of the recovery device has a cover member that can switch between a closed position for restricting the taking out of the object to be processed and an open position for allowing the taking out of the object to be processed. The lower end of the conveyor is provided as a swinging fulcrum so that it can be opened and closed by swinging. It is suitable if it is provided near the opening/closing portion.

According to this configuration, when the object to be processed is taken out, the operation of opening and closing the lid member of the opening and closing portion and the operation of operating and stopping the conveyor can be performed simultaneously while performing the opening and closing operation of the lid member. Therefore, it is easier to open and close the lid member while confirming the condition of taking out the object to be treated from the open/close opening.
In addition, since the cover member is provided so that the lower end side can be opened and closed by swinging with the upper end portion as a swinging fulcrum, when the object to be processed is conveyed toward the opening/closing portion side by the drive of the conveyor, the object to be processed is transported toward the opening/closing portion. The lower end side of the lid member is opened by the pressing action of the object to be treated, and the object to be treated can be discharged from the open/close opening.

〔overall structure〕
1 to 4 illustrate a crop harvester for harvesting edamame as a pod crop.
This crop harvester comprises a pair of left and right crawler type travel devices 11 below a body frame 10 and a control section 12 on the right front portion of the body frame 10 to constitute a travel body 1 .
The traveling body 1 includes a harvesting section 1A for harvesting crops in a field, a dehulling section 1B for dehulling so as to separate the pods of the harvested crops (corresponding to the object to be processed) from the stems, A sorting section 1C for sorting out the depodized material and a collecting section 1D for storing the pods sorted out from the material are provided.

The crop harvesting machine of the present invention is intended to harvest crops with pods, such as green soybeans, kidney beans, and snow peas, which are harvested with pods attached. In this embodiment, the crop with pods refers to the whole state in which the stem part (main stem) has a leaf part (true leaf) and a pod part (pod) attached, and the pod part means that the fruit is enclosed in the pod. It refers to the state in which the

In a crop harvesting machine for harvesting green soybeans, at the time of harvesting by the harvesting section 1A, the green soybeans are extracted with the leaves and roots still attached to the stem portion and conveyed backward. That is, at this harvesting time, the entire crop is harvested as the material to be processed.
In the dehussing section 1B, the pods are dehulled so as to be torn off the pods from the crop whose stems are gripped. At this time, many leaves and part of the stems are also removed from the stems at the same time. separate and fall off. At the time of this hulling treatment, the portion of the crop that has been sent to the hulling section 1B is treated as the material to be treated. After dehulling, the culms such as stems and roots are discharged out of the machine from the rear part of the machine.
In the sorting unit 1C, the pods and leaves separated from the stalks by the depoding process are the objects to be sorted. Then, the object to be processed after removing most of the contaminants such as leaves in the sorting unit 1C is sent to the collecting unit 1D.

A motor unit having an engine 13 is provided on the right front portion of the body frame 10 of the traveling body 1, and the operator's seat 12a of the control unit 12 is installed to cover the upper side of the motor unit. A control section step 12b is provided in front and below the driver's seat 12a, and a control tower 12c having an operating tool for steering operation is provided in front of the control section step 12b.

[Harvesting Department]
The harvesting section 1A will be described.
As shown in FIGS. 1 and 2, the harvesting section 1A is provided with a rearward conveying device 2 that grips a pod-attached crop to be harvested and conveys it backward together with the stalk.
The rearward conveying device 2 includes a long pinching conveying device 20 that picks up the stem portion of the crop in the field and conveys it rearward and upward. It is equipped with a sideways feeding device 24 that changes its posture and delivers it to the following dehulling device 3. The holding and conveying device 20 and the sideways feeding device 24 are arranged on the left side of the traveling body 1 .

The nipping/conveying device 20 has a pair of left and right endless rotating belts 21, 21 with a rear upward tilting posture, the starting end of which is located near the ground, and which is positioned at a higher level on the rear side of the fuselage toward the end of the conveying. The endless rotary belts 21, 21 are wound around a driving pulley 20A, a relay pulley 20B, and a driven pulley 20C and driven, and the stem portion of the crop with pods is sandwiched between the left and right endless rotary belts 21, 21. is configured to

The pair of left and right endless rotating belts 21, 21 is a combination of front rotating belts 21a, 21a positioned on the front side and rear rotating belts 21b, 21b positioned on the rear side with respect to the relay pulley 20B. It is configured.
The relay pulley 20B includes upper and lower pulley portions 20Ba and 20Bb that rotate integrally on the same axis. Forward rotation belts 21a, 21a are wound over an upper pulley portion 20Ba of the relay pulley 20B and the driven pulley 20C. Post-rotating belts 21b, 21b are wound over a lower pulley portion 20Bb of the relay pulley 20B and the driving pulley 20A.

Therefore, when the stem portion of the crop in the field is nipped by the pair of left and right endless rotating belts 21, 21, and the crop is extracted and transported rearward and upward, the stem portion of the crop is changed during transportation. That is, the rear side of the relay pulley 20B is sandwiched by the rear rotation belts 21b, 21b from the stem portion of the crop that was sandwiched by the front rotation belts 21a, 21a on the front side of the relay pulley 20B. will be transported.
When the endless rotating belts 21, 21 are composed of the upper front rotating belts 21a, 21a and the lower rear rotating belts 21b, 21b in this manner, the following advantages are obtained. In other words, when pulling out a crop planted in a field, if an attempt is made to clamp the crop near the root from the beginning, the tips of the endless rotating belts 21, 21 are likely to plunge into the mud of the field, resulting in damage. and may cause malfunction. Compared to this, if the crop planted in the field is pulled out with the crop slightly above the root of the crop being pulled out, there is little risk of damage or failure. After that, if the gripping part is changed to the root side of the crop, and if almost the whole crop is inserted into the pod removing device 3, the pod portion of the crop that is also present near the root can be thrashed with little loss. Easy to process.

Of the front rotation belts 21a, 21a wound over the pulley portion 20Ba on the upper stage side of the relay pulley 20B and the driven pulley 20C, the front rotation belts 21a, 21a are attached to the rear side of the portion facing the crop transport path r1. However, a plurality of guide wheels 21c are provided for suppressing movement to the side away from the crop conveying path r1.
In addition, among the post-rotation belts 21b, 21b wound over the pulley portion 20Bb on the lower side of the relay pulley 20B and the drive pulley 20A, the post-rotation belts 21b and 21b are attached to the rear side of the portion facing the crop transport path r1. A plurality of guide wheels 21d are provided for restraining the belts 21b, 21b from moving away from the crop transport path r1.

The sideways supply device 24 includes a rake rotator 25 having an endless rotary chain 25a and a hoisting hook 25b, and guide plates 26a and 26b for guiding the crop with pods in the sideways direction.
In this sideways feeding device 24, the front portion of the raking rotor 25 overlaps the end portion of the nipping and conveying device 20 in the longitudinal direction, and the rear portion of the raking rotor 25 overlaps the front end portion of the feed chain 27 described later in the longitudinal direction. provided to overlap. That is, the sideways feeding device 24 causes the sideways feeding device 24 to overturn the crop with pods before the rearward feeding action by the nipping and conveying device 20 ends, and the feed chain 27 starts rearward feeding before the sideways feeding device 24 ends the sideways feeding action. As started, the position of the overturned feeding device 24 has been set.
Further, as shown in FIGS. 1 and 2, the end portion of the nipping and conveying device 20 and the front end of the feed chain 27 are also positioned to overlap in the front-rear direction. The nipping and conveying device 20 and the feed chain 27 are arranged so that the conveying area by the feed chain 27 partially overlaps.

Regarding the positional relationship in the vertical direction among the rake rotator 25, the terminal end of the nipping and conveying device 20, and the front end of the feed chain 27, the endless rotary chain 25a of the rake rotator 25 is the highest, and the feed chain is the highest. The front end of 27 is the lowest, and it is arranged so that the terminal end of nipping and conveying device 20 is positioned between them.
In the left-right direction, as shown in FIG. 2, the extension line of the extraction conveying path r1 formed by the nipping and conveying surfaces of the pair of left and right endless rotating belts 21 of the nipping and conveying device 20 is the feed chain in plan view. It is located on the left lateral outside of 27. Then, the endless rotating chain 25a of the raking rotary body 25 overturns the rod of the crop with pods from the left lateral outside of the pulling-out conveying path r1 to the right lateral side beyond the position of the feed chain 27. is provided as follows.

In FIG. 2, of the endless rotating belts 21, 21 of the holding and conveying device 20, the endless rotating belt 21 on the left side rotates clockwise, and the endless rotating belt 21 on the right side rotates counterclockwise. The endless rotary chain 25a of the raking rotor 25 rotates clockwise. The feed chain 27 rotates clockwise in FIG. Reference numeral 28 in FIG. 1 denotes a clamping guide for clamping and conveying the workpiece between itself and the upper surface of the feed chain 27 .

[Decapsulation]
The shelling portion 1B will be described.
As shown in FIGS. 1 to 4, the pod shedding unit 1B is equipped with a pod shedding device 3 (corresponding to a shedding device) for shedding the pods from the stem of the crop with pods. It is
The hulling device 3 includes a pair of upper and lower front rotating shafts 30 and 30 and a pair of upper and lower rear rotating shafts 31 and 31 .

The upper and lower front rotating shaft bodies 30, 30 located on the front side are driven to rotate counterclockwise and clockwise, respectively. Although not shown, each of the front rotating shafts 30, 30 has a cross-sectional shape in which a plate-like protruding member protrudes from the outer peripheral surface of a cylindrical body, and is driven to rotate so as to rake in the object to be processed. be done.
The upper and lower rear rotating shafts 31, 31 positioned on the rear side are driven to rotate counterclockwise and clockwise, respectively. Each of the rear rotating shafts 31, 31 has a cross-sectional shape in which a wide plate-like projecting member protrudes from the outer peripheral surface (not shown), and is driven to rotate so as to scrape the object to be processed.

The front rotating shafts 30, 30 and the rear rotating shafts 31, 31 are arranged on both sides of the nipping/conveying surface 27a of the feed chain 27 so as to be separated from each other.
Therefore, the upper portion of the crop with pods whose root side is sandwiched by the feed chain 27 is located between the upper front rotating shaft 30 and the lower front rotating shaft 30, and between the upper rear rotating shaft 31 and the lower portion. When passing between the rear rotary shafts 31 on the side, it is hit and squeezed by the front rotary shafts 30,30 and the rear rotary shafts 31,31. In this way, the stem portion that is clamped and pulled by the feed chain 27 is also subjected to squeezing when passing between the upper and lower front rotary shafts 30, 30 and the rear rotary shafts 31, 31. The pod portion is efficiently stripped off from the stem portion. The dehulling process is performed in this manner.

The objects to be treated, including the pods and leaves that have fallen off the stems, fall onto the receiving conveyor 32 and are sent rearward for sorting. The stem portion from which the pod portion has been removed is conveyed rearward while being sandwiched by the feed chain 27, and is dropped and discharged out of the machine body from the rear end of the machine body. The upper surface of the feed chain 27 is a pinching and conveying surface 27a, and the stem portion can be pinched between a pinching guide 28 facing the upper surface.

[Sorting part]
The sorting unit 1C will be described.
The sorting unit 1C is equipped with a sorting device 4 for sorting the material to be processed after depoding.
The sorting device 4 is provided with a primary sorting section 4A for wind sorting and a secondary sorting section 4B for sieving sorting.
The primary sorting section 4A is provided with a winnow 40 that generates a sorting wind and a sorting conveyor 41 that conveys the objects to be processed rearward.
The secondary sorting section 4B is provided with a horizontal conveyer 42 (corresponding to a relay conveying device) that conveys the objects to be processed after the wind selection process to the collection section 1D side.

In the primary sorting section 4A, the winnow 40 is arranged below the receiving conveyor 32 of the pod removing device 3. As shown in FIG. Between the terminal end of the receiving conveyor 32 and the starting end of the sorting conveyor 41 , the sorting conveyor 41 is arranged with the starting end positioned slightly lower than the terminal end of the receiving conveyor 32 . Between the start end of the sorting conveyor 41 and the end of the receiving conveyor 32, dust with a small specific gravity and leaves with a large surface area float and are transferred to the sorting conveyor 41 side in the air blown state by the winnow 40. Spaces suitable for wind selection are provided so that the pods with high specific gravity will fall.

In the secondary sorting section 4B, the horizontal conveyer 42 is connected to the starting end of the sorting conveyor 41 and the receiving conveyor 32 so that the pods, etc., which have a relatively large specific gravity and fall, can be caught during the wind sorting process in the primary sorting section 4A. It is arranged below the interval suitable for the wind separation treatment provided between the end of the
As shown in FIGS. 2 and 4, the horizontal conveyer 42 conveys the objects to be processed after the wind selection process to the collection section 1D side. Therefore, it is extended in the left-right direction from the primary sorting section 4A arranged on the left side of the traveling body 1 toward the collection section 1D near the right end.

As shown in FIG. 4, the horizontal conveyer 42 is provided with an upwardly inclined conveying surface 42a in which the conveying terminal side is higher than the conveying starting end side. The upward slope of the horizontal conveyer 42 makes it easier to level the deposits when the objects to be processed that have fallen during the air separation process in the primary sorting section 4A are accumulated on the left end of the conveying surface 42a. It is for
In other words, when the sediment moves on an upward inclined surface, it is conveyed with a slight degree of gravity acting on the rearward side of the conveyance, rather than when the sediment moves on a mere horizontal surface. The mountains are easy to collapse, and the vibration of the machine body works effectively, so that the sediment can be conveyed while leveling it during the conveyance.

At the terminal end of the horizontal conveyor 42, a chute member 43 having an inclined surface is provided for sliding down while guiding in a downwardly forward posture toward the recovery section 1D. A sensor 44 is provided at a lateral side position of the inclined surface portion of the chute member 43 for detecting the existence of a predetermined amount or more of workpieces on the inclined surface.
This sensor 44 is for determining whether or not a predetermined amount or more of the objects to be processed are accumulated on the side of the collecting device 5 when the objects to be processed are supplied from the horizontal conveyer 42 to the collecting device 5. . That is, in a state in which a predetermined amount or more of the objects to be processed is not accumulated on the recovery device 5 side, the objects to be processed supplied from the horizontal conveyer 42 flow down without stagnation on the inclined surface portion of the chute member 43. Existence of a predetermined amount or more of the workpiece on the inclined surface 43 is not detected. When a predetermined amount or more of the objects to be processed accumulates on the collecting device 5 side, the objects to be processed are stagnated on the inclined surface portion of the chute member 43, and a state in which the predetermined amount or more of the objects to be processed exists on the inclined surface is detected.

It is constructed such that it can be inserted into and removed from an engaging hole 50c provided in the portion 50b.
Therefore, when the knob handle 53a is rotated clockwise as viewed from the rear, the lock pins 53c engage with the engagement holes 50c provided in the left and right vertical wall portions 50b to enter a locked state. , the respective lock pins 53c, 53c are disengaged from the right and left engaging holes 50c to be in the unlocked state, and the lid member 52 can be opened and closed.

A manual operation switch 54 (corresponding to an operation switch) for manually driving and operating the belt conveyor 51 in forward and reverse directions is provided near the opening/closing portion 50d and at the outer position of the vertical wall portion 50b on the outer side of the machine body. ing.
The manual operation switch 54 is of a neutral return type and is constructed as a tumbler operation type that can be selectively operated in one direction or the opposite direction. Only while the manual operation switch 54 is operated in one direction, the belt conveyor 51 is driven so as to convey the material to be processed in the positive direction toward the end position A2, which is horizontally separated from the recovery start point A1. Only while the manual operation switch 54 is operated in the direction opposite to the one direction, the belt conveyor 51 is driven in a state of conveying the workpiece in the opposite direction from the end position A2 to the collection start point A1. When neither is operated, the belt conveyor 51 is stopped.

The belt conveyor 51 is driven by an electric motor 55 attached to the recovery section support base 14 near the recovery start point A1 and below the belt conveyor 51 as a drive source.
Rotational power of the electric motor 55 is input to the belt drive shaft 56 of the belt conveyor 51 via the drive sprocket 55a, the transmission chain 55b, and the driven sprocket 55c. A conveyor drive rotating body 56a is provided at the end of the belt drive shaft 56 opposite to the driven sprocket 55c so as to be able to rotate integrally therewith.

The recovery operation in the recovery device 5 is performed as follows.
That is, during the harvesting operation, when a predetermined amount or more of the material to be processed accumulates at the collection start point A1, the sensor 44 provided on the chute member 43 at the terminal end of the horizontal conveyer 42 is positioned on the inclined surface of the chute member 43. By detecting the presence of a predetermined amount or more of the material to be processed, it is recognized that a predetermined amount or more of the material to be processed has accumulated at the collection start point A1.

A detection signal from the sensor 44 is transmitted to a control device (not shown) for the electric motor 55, and the control device drives the electric motor 55 in the positive direction (from the collection start point A1 to the end position A2) for a predetermined period of time. direction).
Then, the belt conveyor 51 moves in the positive direction by a predetermined amount with the object to be processed still placed thereon. As a result, the objects to be treated that have remained on the inclined surface of the chute member 43 flow down. As a result, the sensor 44 provided on the chute member 43 detects that the object to be processed is absent, and the supply of the object to be processed from the horizontal conveyer 42 to the container 50 is resumed.

When the sensor 44 provided on the chute member 43 at the terminal end of the horizontal conveyer 42 again detects that there is a predetermined amount or more of the objects to be processed on the inclined surface of the chute member 43, it moves a predetermined amount from the collection start point A1. It is recognized that a predetermined amount or more of the object to be processed has accumulated in the storage unit 50 at the location where the object has been detected.
Along with this, the control device operates the electric motor 55 in the forward direction (direction from the recovery start position A1 to the end position A2) for a predetermined period of time.

While repeating such an operation several times, the full sensor 59 provided on the vertical wall portion 50b detects the presence of the object to be processed at the end position A2 which is horizontally away from the collection start position A1.
As a result, it is detected that the entire housing portion 50 is full, and the control device outputs an alarm sound, voice, or alarm lamp, or A warning is given to the driver by both of them.
