Description

The present invention is a poded crop harvesting device comprising a nipping and conveying device that pulls out a podded crop to be harvested and conveys it backward, and a pod-throwing device that treats the pods of the podded crop so that the pods fall off the stalk. Regarding the machine.

As a crop harvester with pods of this type, there is one that has a nipping device constituted by an endless belt chain in the front part of the machine body and a conveying device constituted by an endless flexible belt on the rear side (Patent document 1).

Japanese Patent Application Laid-Open No. 6-78620 (paragraphs “0014”, “0026”, see FIGS. 1 and 2)

In Patent Document 1, an endless belt chain provided at the lower part of the front part of the machine body pinches the stalk of green soybeans, pulls it out while transporting it rearward and upward, and delivers it to a subsequent conveying device constituted by an endless flexible belt. A technique is disclosed in which the pods are dehulled by a rear dehuller.
According to this structure, the edamame planted in the field is pulled up together with the stalk and transported backward, so that the edamame can be harvested without leaving any stumps or the like, and the field can be easily managed after the edamame is pulled out.

However, in the structure described in Patent Document 1, the endless belt chain provided at the lower part of the front part of the machine body grips a position near the lower end of the edamame stalk, making it easy to pull out the edamame. However, since the endless belt chain is located too close to the ground, a pair of left and right ground plates are required to prevent it from penetrating into the ground, and there is a risk that the endless belt chain will be damaged by mud and pebbles getting caught. There was a problem such as
In addition, since the trailing endless flexible belt grips the stem part at a position farther from the lower end than the gripping position of the endless belt chain, the leaf stem part and the pod part near the base of the edamame are gripped. , there was a problem that it was difficult to insert into the deep part of the dehulling device.

Furthermore, in the structure described in Patent Document 1, the power transmission structure for the endless belt chain at the front of the body is provided separately from the drive structure for the following endless flexible belt, so the power transmission structure is complicated. There is also a problem in that it tends to increase the weight of the aircraft and increase the weight of the aircraft.

The present invention enables the tip side of a nipping and conveying device for pulling out and rearwardly conveying crops with pods without bringing them too close to the ground, while inserting the crops with pods deep into the threshing device. To provide a pod-equipped crop harvester which is easy to operate and can simplify the power transmission structure.

Features of the crop harvester with pods according to the present invention are:
A nipping and conveying device for pulling out and rearwardly conveying a crop with pods to be harvested, a removing device for processing the pod portion of the crop with pods fed through the nipping and conveying device so as to drop the pod portion from the stem portion, and the nipping and conveying. A pod-equipped crop harvester equipped with a traveling device that supports a body frame on which a device and a threshing device are mounted,
The nipping and conveying device includes a pair of left and right endless rotating belts for gripping the stalk portion of the crop with pods, and between the facing surfaces of the left and right endless rotating belts, a crop conveying path is formed along the traveling direction of the machine body. is,
The endless rotating belt is composed of a combination of a front rotating belt positioned at the front part of the crop transport path and a rear rotating belt positioned at the rear part of the crop transport path,
A relay pulley is provided for transmitting a driving force from the front end of the rear rotation belt to the rear end of the front rotation belt, and the rear end of the front rotation belt is wound around the upper stage of the relay pulley, a front end portion of the rear rotation belt is wound around the lower stage portion of the relay pulley;
The movement of the front rotation belt and the rear rotation belt toward the side away from the crop transportation path is provided on the rear side of the portion of the front rotation belt and the rear rotation belt that faces the crop transportation path. guide wheels for suppressing are provided at locations facing each other at positions sandwiching the crop transport path,
The guide wheels are provided at a plurality of locations in each of the front rotation belt and the rear rotation belt in a direction along the front-rear direction of the crop conveying path,
The arrangement pitch in the front-rear direction of the guide wheels of the front rotation belt is set shorter than the arrangement pitch in the front-rear direction of the guide wheels of the rear rotation belt.
The nipping and conveying device is provided with a belt support frame that supports the endless rotating belt,
The belt support frame includes a right frame that supports the endless rotating belt on the right and a left frame that supports the endless rotating belt on the left,
The right frame and the left frame are connected by a lower connecting member that bypasses the lower side of the front rotating belt in the crop transport path,
The lower end portion of the lower connecting member connects the ground surface of the traveling device and the front end portion of the pinching and conveying device in a working posture in which the front end portion of the pinching and conveying device is positioned low enough to touch the field. It lies in a point located almost on the same line as the line segment .

According to the present invention, the rear rotation belt on the rear side of the front rotation belt located in the front part of the crop conveying path conveys the crop rearward while gripping the lower side of the gripping position of the stem portion by the front rotation belt. . Therefore, even if the front end portion of the front rotation belt is not placed extremely close to the ground, the rear rotation belt can convey the crop with pods rearward while gripping closer to the root.
As a result, it is possible to reduce the risk of causing damage due to a large amount of mud or pebbles getting caught in the front end of the front rotation belt too close to the ground. Conveyance by the rotating belt has the advantage of facilitating the removal of pods while the crop with pods is inserted into the deep part of the removal device.
Further, by using the relay pulley, the driving force to the front rotation belt can be transmitted by the rear rotation belt, which is advantageous in that the power transmission structure can be simplified and the weight of the transmission structure can be reduced.
Further, according to the present invention, by using the guide wheels, the clamping action of the front rotation belt and the rear rotation belt is ensured, and the arrangement pitch of the front rotation belts on the guide wheels in the front-rear direction is reduced. , and is set shorter than the arrangement pitch in the front-rear direction of the guide wheels of the rear rotation belt so that the front rotation belt can pull out the belt well.
That is, the pitch of the guide wheels of the front rotating belt in the front-rear direction is smaller than the pitch of the guide wheels of the rear rotating belt in the front-rear direction. As a result, the movement of the front rotating belt, to which a relatively large external force may be applied during the pull-out operation, to the side away from the crop conveying path is more strongly suppressed, thereby making it easier to maintain the required pinching operation. be.

According to this configuration, since the relay pulley is provided between the front side lower connecting member and the rear side lower connecting member, the front and rear lower portions can also be used as reinforcement means for external force acting on the mounting location of the relay pulley. The connecting member can be utilized, and the structure can be simplified by sharing parts.

In the above configuration, it is preferable that the lower connecting member located on the front side of the relay pulley among the lower connecting members is provided with a support portion that supports the front end portion of the uncut side dividing rod.

According to this configuration, the lower connecting member located on the front side can be used as a support portion for supporting the front end portion of the uncut side branch rod, and the structure can be simplified by sharing parts.

〔overall structure〕
1 to 4 illustrate a pod crop harvester for harvesting edamame as a pod crop.
This pod-equipped crop harvester comprises a pair of left and right crawler-type traveling 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 traveling 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 recovery section 1D for storing the pod portion sorted out from the material are provided. place

The crops with pods harvested by the harvester of crops with pods of the present invention are crops with pods, such as green soybeans, kidney beans, and snow peas. 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 pod-equipped crop harvester for harvesting edamame, at the time of harvesting by the harvesting section 1A, the edamame is extracted with the leaves and roots still attached to the stem 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 .

[Clamping and Conveying Device]
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 rotating belts 21, 21 are wound around a drive pulley 20A, a relay pulley 20B, and a driven pulley 20C and driven. Between the left and right endless rotating belts 21, 21, a crop conveying path r1 for pinching and conveying the stalk portion of the crop with pods is formed along the traveling direction of the machine body.

As shown in FIGS. 1 and 2 and FIGS. 5 and 6, the pair of left and right endless rotating belts 21 and 21 are composed of front rotating belts 21a and 21a located on the front side with respect to the relay pulley 20B, and front rotating belts 21a and 21a on the rear side. and rear rotation belts 21b, 21b located at .
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. Since the crops with pods are conveyed, the position where the crop with pods is pinched by the rear rotation belts 21b, 21b is closer to the root of the crop than the position where it is pinched by the front rotation belts 21a, 21a.
When the crop is inserted into the hulling device 3 in this state, the tip side of the crop is inserted into the hulling device 3 rather than the pinched portion, and almost the entire crop is inserted into the hulling device 3. It is easy to remove the pods of the crops that are present in the pods with little loss.

The nipping and conveying device 20 is provided with a belt support frame 22 that supports a pair of left and right endless rotating belts 21 , 21 .
The belt support frame 22 includes a right frame 22R that supports the right endless rotary belts 21 and 21, and a left frame 22L that supports the left endless rotary belts 21 and 21. As shown in FIG.
The right frame 22R and the left frame 22L are connected at a plurality of locations before and after the crop conveying route r1 by lower connecting members 23 that bypass the lower side of the crop conveying route r1, and the right frame 22R and the left frame 22L are integrated. has been made

As shown in FIG. 7, of the lower connecting members 23, the lower connecting member 23 positioned forward of the relay pulley 20B includes side plate portions 23a extending downward from the right frame 22R and the left frame 22L, A pipe-shaped connector 23b that connects the left and right side plate portions 23a is integrated with each other, and is formed in a U shape that bypasses the lower side of the crop transport route r1 when viewed in the front-rear direction.
A lateral portion of the left side plate portion 23a of the lower connecting member 23 is provided with a support portion 23c that supports the front end portion of the round bar-shaped uncut side branch rod 15 in a state of being inserted into the hole. That is, the front lower connecting member 23 also serves as support means for supporting the front end portion of the uncut side dividing rod 15 .

Further, as shown in FIG. 5, the connecting body 23b positioned at the lower end of the lower connecting member 23 on the front side is, as shown in FIG. It is positioned substantially on the same line as the imaginary line segment GL connecting the ground contact surface of the traveling device 11 of the formula and the front end portion of the nipping and conveying device 20 .
The lower edge of the driven pulley 20C around which the endless rotating belts 21, 21 are wound is also substantially the same as the imaginary line segment GL that connects the ground surface of the crawler-type traveling device 11 and the front end portion of the nipping and conveying device 20. located on the line.
Therefore, when the front end portion of the nipping and conveying device 20 is positioned low enough to contact the field, the connection body 23b positioned at the lower end of the lower connecting member 23 on the front side is also low enough to contact the field. in a low position. As a result, the connecting body 23b is also useful as a sinking resistance when the front end portion of the holding and conveying device 20 or the lower edge portion of the driven pulley 20C is about to plunge into the ground.

Of the lower connecting members 23, the lower connecting member 23 located on the rear side of the relay pulley 20B includes side plate portions 23a extending downward from the right frame 22R and the left frame 22L, and left and right side plate portions 23a. It is integrated with a rectangular pipe-shaped connector 23b that connects them, and is formed in a U shape that bypasses the lower side of the crop transport route r1 when viewed in the front-rear direction.
The connecting body 23b of the lower connecting member 23 is provided with a cylinder mounting portion 23d capable of connecting the front end side of the lifting cylinder 16 for moving the front end side of the clamping and conveying device 20 up and down. In other words, the lower connecting member 23 on the rear side also serves as a mounting portion for the front end side of the lifting cylinder 16 .

As described above, the relay pulley 20B is provided between the lower connecting member 23 on the front side and the lower connecting member 23 on the rear side in the front-rear direction of the crop transport route r1. Therefore, the front and rear lower connecting members 23 also serve as means for reinforcing the periphery of the mounting location of the relay pulley 20B.

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 route 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.

As shown in FIG. 6, among the guide wheels 21c and 21d, the arrangement pitch P1 of the plurality of guide wheels 21c provided on the front rotation belts 21a and 21a is equal to that of the rear rotation belts 21b and 21b. It is set shorter than the arrangement pitch P2 of the plurality of provided guide wheels 21d.
Further, in the endless rotating belt 21, the clamping pressure in the crop conveying route r1 by the front rotating belts 21a, 21a is set to be slightly higher than the clamping pressure in the crop conveying route r1 by the rear rotating belts 21b, 21b. I have
When the stalk portion of the crop is strongly gripped by the front rotation belts 21a, 21a and the crop is pulled out by slightly increasing the clamping pressure, the front rotation belts 21a, 21a absorb the reaction force of the crop to be clamped. The phenomenon of receiving and deforming away from the crop transport path r1 is suppressed by shortening the arrangement pitch P1 of the plurality of guide wheels 21c.

[Lay down feeding device]
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 horizontal direction, as shown in FIG. 2, the extension of the crop transport path r1 formed by the clamping and transporting surfaces of the pair of left and right endless rotating belts 21 of the clamping and transporting device 20 is the feed chain in plan view. It is located on the left lateral outside of 27. Then, the endless rotary chain 25a of the raking rotary body 25 overturns the position of the feed chain 27 from the left lateral outside of the crop conveying path r1 and overturns the rod of the crop with pods toward the right lateral side. 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 shelling device 3 includes a pair of upper and lower front rotary shafts 30, 30 and a pair of upper and lower rear rotary shafts 31, 31. As shown in FIG.

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 from the rear end of the machine body. The feed chain 27 has a pinching and conveying surface 27a on the upper surface side, and can pinch the stem portion between it and a pinching guide 28 facing the upper surface side.

[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.

[Recovery part]
The collection unit 1D will be described.
The recovery section 1D is configured by a recovery device 5 provided along the front-rear direction of the traveling body 1 on the right side of the body frame 10 .
The recovery device 5 includes a long container 50 extending from a recovery start point A1 at which the material to be processed is transferred from the horizontal conveyer 42 and an end position A2 horizontally separated from the recovery start point A1. . The storage section 50 has a bottom surface 50 a formed of a belt conveyor 51 (corresponding to a conveyor) capable of conveying the object to be processed in the longitudinal direction of the storage section 50 .

The storage unit 50 is configured separately from the belt conveyor 51, has a vertical wall portion 50b that protrudes upward from the upper surface of the belt conveyor 51, and is elongated in the front-rear direction in a plan view together with a lid member 52 described later. It is formed in a rectangular box shape.
The vertical wall portion 50b extends along the object conveying direction of the belt conveyor 51 and is located on the right side of the body frame 10 at both laterally outer positions of the belt conveyor 51 and the front end portion in the object conveying direction of the belt conveyor 51. It is fixedly installed on the recovery part support stand 14 provided on the side part.
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.

With respect to the conveying direction of the object to be processed by the belt conveyor 51, the housing portion 50 at the location corresponding to the rear end portion opposite to the front end portion in the conveying direction of the object to be processed has an opening/closing portion 50d from which the object to be processed can be taken out. is provided.
