Description

The present invention relates to a pod harvester for harvesting green soybeans, green beans, snow peas, etc. among agricultural products in a podded state.

In this type of pod harvester, the crops in the field are cut as the object to be processed, transported upward to the rear by the pinching transport device, the pods are peeled off by the pod removal device at the rear, and then the wind selection process is performed to produce good products. There is a structure in which the pod portion of the bean is collected in a bucket on the lateral side (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2000-201519 (see paragraph "0044", FIGS. 5 and 6)

In the structure shown in Patent Document 1, a large amount of leaf debris falls on the edamame receiving device composed of a conveyor belt together with the pod portion during the pod removal process in which the pod portion is peeled off by the pod removal device. Then, it is sent to the sorting device as it is and processed by wind selection. The foliage portion of the object to be de-pod-treated is discharged rearward from the end of the delivery device. This is useful in that the edamame harvesting work can be performed efficiently, but it has the following problems.
In other words, in the sorting by the wind sorting process, relatively small leaf debris and dust with a small mass are blown off by the sorting wind, and the pods having a relatively large mass can be effectively dropped and collected. Is. However, if the total amount of pod-attached crops to be treated is temporarily increased, or if the amount of leaf debris that has fallen off along with the pods is extremely large, clogging will occur at the exit from the sorting point. As a result, there was a risk that the wind selection action could not be performed accurately.

INDUSTRIAL APPLICABILITY The present invention is intended to suppress the occurrence of clogging at a sorting point when harvesting a pod-bearing crop so that the wind selection work can be performed without any trouble.

The features of the pod harvester in the present invention are a rear transport device that grips the foliage portion of the pod-bearing crop to be treated and transports the pods backward, and the object to be processed fed by the rear transport device from the foliage portion. A pod harvester equipped with a pod removal device for removing pods so as to remove the pods and a sorting device for sorting the object to be processed after the pod removal treatment. A blower that supplies sorting air toward the object to be processed, a delivery device that grips near the root of the foliage portion of the object to be processed and feeds it backward, and a rotary feed device that has a drum-shaped outer peripheral surface. The rotary feeding device is provided so as to be arranged along the rotation axis in a direction intersecting the feeding direction of the object to be processed by the feeding device in a plan view, and the foliage of the object to be processed is provided on the outer peripheral surface. Handle teeth that act on the part are formed.

According to the present invention, the sorting device is provided with a rotary feed device having a drum-shaped outer peripheral surface that comes into contact with the object to be sorted. In this rotary feed device, since the rotary feed device has a drum shape, the sorting supplied from the blower device is compared with the belt conveyor type sorting means arranged in a state along the blowing direction of the sorting air from the blower device. It is easy to secure a relatively large area in contact with the wind, and it is easy to effectively stir the object to be processed by the sorting wind at the sorting location. At the same time as the sorting process, the rotary feeding device also exerts a feeding action on the culm portion of the object to be processed, so that the sorting performance can be easily improved.
Then, since the handle teeth that act on the foliage portion of the object to be processed are formed on the drum-shaped outer peripheral surface of the rotary feed device, the rotary feed device feeds the object to be processed to the rear side that acts on the foliage portion. It is easy to exert the action surely. It is easy to avoid the occurrence of clogging at this sorting point as much as possible.

In the above configuration, in the rotary feeding device, the upper part of the outer peripheral surface is at a height position equal to the height of the sandwiching and transporting surface of the feeding device, and the front part of the outer peripheral surface is the blower. It is preferable that it is arranged at a position intersecting the blowing direction of the sorting wind.

According to this configuration, the rotary feed device in which the upper part of the outer peripheral surface is at a height similar to the height of the pinch transport surface of the feed device includes the foliage portion during pinch transport in cooperation with the feed device. Since the object to be processed is positively fed backward, it is easy to avoid clogging of the object to be processed in this portion.

In the above configuration, a lateral feed transfer device that receives the pod portion of the object to be dropped and laterally feeds it in the left-right direction is provided below the rotary feed device, and the rotary feed device is after the lateral feed transfer device. It is preferable that the rotation axis is arranged in a state where the rotation axis is located on the front side of the end.

According to this configuration, at the sorting portion on the front side of the drum-shaped outer peripheral surface of the rotary feed device, the light dust to be discharged among the objects to be processed is due to the blowing action by the sorting wind and the lifting action by the rotary feed device. Etc. are sent backward and upward. Then, the object to be processed, that is, the pod part of a non-defective product, which was not discharged upward and backward due to the blowing action by the sorting wind and the lifting action by the rotary feeding device, falls on the front side of the drum-shaped outer peripheral surface of the rotary feeding device. However, it is possible to reliably and easily collect the pods and the like of this non-defective product.

In the above configuration, in the rotary feed device, the handle teeth are planted at a plurality of locations on the outer peripheral surface in the circumferential direction and in the direction along the rotation axis, and the circumferential direction. Alternatively, it is said that the planting intervals in the direction along the rotation axis are provided so as to be closer to the portion closer to the tip than the side closer to the root of the object to be processed gripped by the delivery device. Suitable.

According to this configuration, the planting interval of the teeth to be treated is set so that the portion corresponding to the side closer to the tip of the object to be processed is closer than the side closer to the root of the object to be processed held by the delivery device. Therefore, it is easy to reliably exert the sending action on the foliage portion of the object to be treated. This makes it easier to avoid clogging of the object to be processed.

In the above configuration, it is preferable that the handle teeth are fixed by inserting a removable bolt member into a mounting hole formed on the outer peripheral surface of the rotary feed device.

According to this configuration, it is easy to perform mounting work of the handle teeth, change of mounting position, and the like.

It is explanatory drawing in plan view which shows the pod removal part and the sorting part. It is explanatory drawing in the side view which shows the rotary feed device.

Hereinafter, an example of the embodiment of the present invention will be described based on the description in the drawings.
Unless otherwise specified, the front-rear direction and the left-right direction in the description of the present embodiment are described as follows. That is, in the pod harvester to which the present invention is applied, the traveling direction on the forward side (see arrows F in FIGS. 1 and 2) during the working travel of the traveling machine 1 is "forward", and the traveling direction on the reverse side (FIG. 1). , 2 (see arrow B in FIG. 2) is "rear", the direction corresponding to the right side based on the forward-looking posture in the front-back direction (see arrow R in FIG. 2) is "right", and similarly the direction corresponding to the left side (see FIG. 2).

FIGS. 1 to 5 exemplify a pod harvester for harvesting edamame as a pod-attached crop.
This pod harvester is provided with a pair of left and right crawler-type traveling devices 11 below the body frame 10, and a control unit 12 on the right front portion on the body frame 10 to form the traveling machine 1.
The traveling machine 1 includes a harvesting section 1A for harvesting crops in the field, a pod removing section 1B for removing the pods of the harvested crops (corresponding to the object to be treated) so as to separate them from the stem portions. A sorting unit 1C for selecting the depoded object to be processed and a collecting unit 1D for accommodating the pod portion selected from the object to be processed are provided.

The pod-harvesting machine of the present invention targets pod-bearing crops such as green soybeans, green beans, and peas, which are harvested in a pod-mounted state. The pod-attached crop in this embodiment refers to the whole state in which the stem portion (main stem) has leaves (true leaves) and pods (pods), and the foliage portion means that the main stem has true leaves. The pod part refers to the one in which the fruit is contained in the pod. The object to be treated refers to the entire crop with pods, to each of the stem, leaves, and pods separated by pod removal or sorting, or together with the crop with pods. In some cases, it refers to all the weeds that have been treated.

In a pod harvester that targets green soybeans, at the time of harvesting by the harvesting unit 1A, the edamame is harvested with the leaves attached to the stems and transported backward. That is, at the time of this harvest, the entire harvested crop is harvested as the object to be processed.
In the pod removal portion 1B, the pod portion is removed from the crop in which the stem portion is gripped so as to be peeled off. At this time, many leaves and a part of the stem are also simultaneously removed from the stem portion. Separated and dropped out. At the time of this pod removal treatment, the portion of the crop sent to the pod removal portion 1B is treated as an object to be treated. The culm parts such as stems and leaves after the pod removal treatment are discharged from the rear part of the machine body to the outside of the machine such as a field.
In the sorting unit 1C, the pod portion and the leaf portion separated from the stem portion by the pod removal treatment are the objects to be sorted. Then, the object to be treated after most of the impurities such as the leaves have been removed by the sorting unit 1C is sent to the collecting unit 1D.

A driving portion including an engine 13 is provided on the right front portion of the fuselage frame 10 of the traveling aircraft 1, and a driver's seat 12a of the control portion 12 is installed so as to cover the upper side of the driving portion. A control unit step 12b is provided below the front of the driver's seat 12a, and a control tower 12c provided with an operating tool for steering operation is provided at the front portion of the control unit step 12b.

[Harvest Department]
The harvesting unit 1A will be described.
As shown in FIGS. 1 and 2, the harvesting unit 1A is provided with a rear transport device 2 that grips the pod-bearing crop to be harvested and transports the entire stem backward.
The rear transport device 2 is a long pinch transport device 20 that transports the stalks of the crops in the field upward and rearward, and a transport end portion of the pinch transport device 20 that lays the upper part of the crop in a sideways posture. It is provided with a sideways supply device 23 that is modified and delivered to the subsequent pod removal device 3. These sandwiching and transporting devices 20 and the sideways feeding device 23 are arranged on the left side of the traveling machine body 1.

The sandwiching and transporting device 20 includes a pair of left and right endless rotating belts 20a and 20a in a rear-upward tilting posture in which the transport start end is located near the ground and the transport end is located at a higher level on the rear side of the machine body, and the endless rotation thereof. The drive pulley 20b and the driven pulley 20c around which the belts 20a and 20a are wound are provided, and the stem portion of the podged crop is sandwiched between the left and right endless rotating belts 20a and 20a.
Further, in the sandwiching and transporting device 20, a stem located near the root of the planted crop is attached to the front portion of the support frame 21 that supports the endless rotating belts 20a and 20a, the driving pulley 20b, and the driven pulley 20c. A rotary cutter 22 is attached as a cutting device for cutting a portion.
Therefore, in the pinching and transporting device 20, the stem portion of the planted crop is sandwiched between the pair of left and right endless rotating belts 20a and 20a, and the stem portion near the root of the planted crop is cut by the rotary cutter 22. Then, the cut crops with pods are conveyed backward and upward in a state of being gripped by the endless rotating belts 20a and 20a.

The sideways feeding device 23 includes a scraping rotating body 24 provided with an endless rotating chain 24a and an undulating claw 24b, and guide plates 25a and 25b for guiding the sideways falling direction of the podged crop.
In the sideways feeding device 23, the front portion of the scraping rotating body 24 overlaps the terminal portion of the sandwiching and conveying device 20 in the front-rear direction, and the rear portion of the scraping rotating body 24 overlaps the front end portion of the feed chain 26 described later in the front-rear direction. It is provided so as to overlap. That is, the sideways feeding action of the pod-bearing crop by the sideways feeding device 23 acts before the end of the rearward carrying action by the pinching transport device 20, and the rearward feeding by the feed chain 26 is performed before the end of the sideways carrying action by the sideways feeding device 23. The arrangement position of the sideways feeding device 23 is set so as to be started.
Further, as shown in FIGS. 1 and 2, the terminal portion of the pinch transport device 20 and the front end portion of the feed chain 26 are also in a positional relationship overlapping in the front-rear direction, and the pinch transport area of the podted crop by the pinch transport device 20 and the pinch transport area. The sandwiching and transporting device 20 and the feed chain 26 are arranged so that the transporting area by the feed chain 26 partially overlaps.

The vertical positional relationship between the scraping rotating body 24, the terminal portion of the sandwiching and conveying device 20, and the front end portion of the feed chain 26 is highest in the endless rotating chain 24a of the scraping rotating body 24, and the feed chain. The front end portion of the 26 is the lowest, and the end portion of the sandwiching transfer device 20 is arranged so as to be sandwiched between them.
Further, in the left-right direction, as shown in FIG. 2, the extension line of the vertical transport path r1 formed by the pinch transport surfaces of the pair of left and right endless rotating belts 20a and 20a of the pinch transport device 20 is a feed chain in a plan view. It is located on the left lateral outside of 26. Then, the endless rotating chain 24a of the scraping rotating body 24 crosses the position of the feed chain 26 from the left lateral outside of the vertical transport path r1 and lays down the rod of the podged crop toward the right lateral side. It is provided as follows.

In FIG. 2, of the endless rotating belts 20a and 20a of the holding and conveying device 20, the left endless rotating belt 20a rotates clockwise, and the right endless rotating belt 20a rotates counterclockwise. The endless rotating chain 24a of the scraping rotating body 24 is rotating clockwise. The feed chain 26 is rotating clockwise in FIG.

[Unpod part]
The pod removal portion 1B will be described.
As shown in FIGS. 1 to 5, the pod-removing portion 1B is provided with a pod-removing device 3 for removing the pods from the stem portion of the pod-attached crop.
The pod removal 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.

Each of the upper and lower front rotating shafts 30 and 30 located on the front side is rotationally driven by an upper rotating shaft 30a that rotates counterclockwise and a lower rotating shaft 30a that rotates clockwise.
Each of the front rotating shaft bodies 30 and 30 is formed in a cross-sectional shape in which a plate-shaped protruding member protrudes on the outer peripheral surface of the round tubular body portion, and is rotationally driven so as to scrape the object to be processed.
Each of the upper and lower rear rotating shafts 31 and 31 located on the rear side is rotationally driven by an upper rotating shaft 31a that rotates counterclockwise and a lower rotating shaft 31a that rotates clockwise.
Each of the rear rotating shaft bodies 31 and 31 is formed in a cross-sectional shape in which a wide plate-shaped protruding member projects on the outer peripheral surface of the rotating shaft 31a, and is rotationally driven so as to scrape the object to be processed.

The front rotating shaft bodies 30 and 30 and the rear rotating shaft bodies 31 and 31 are arranged on the upper side and the lower side of the feed chain 26 with the sandwiching and transporting surface 26a interposed therebetween.
Therefore, the foliage portion of the pod-bearing crop whose root side is gripped by the feed chain 26 is between the upper front rotation shaft body 30 and the lower front rotation shaft body 30, and with the upper rear rotation shaft body 31. As it passes between the lower rear rotating shafts 31, it is struck and squeezed by the front rotating shafts 30 and 30 and the rear rotating shafts 31 and 31. In this way, the stalk portion that is sandwiched and pulled by the feed chain 26 is also subjected to the ironing that is received when passing between the upper and lower front rotating shafts 30 and 30 and the rear rotating shafts 31 and 31. The pods are efficiently peeled off from the foliage. The pod removal process is performed in this way.

The object to be treated including the pod portion and the leaf portion that have fallen off from the foliage portion falls on the receiving conveyor 32 and is sent to the rear for sorting processing. The foliage portion from which the pod portion has been removed is transported backward while being sandwiched by the feed chain 26, and is dropped and released from the rear end portion of the machine body to the outside of the machine body. The upper surface side of the feed chain 26 is the sandwiching transport surface 26a, and the stem portion can be sandwiched between the feed chain 26 and the sandwiching guide 27 facing the upper surface side.

[Sort section]
The sorting unit 1C will be described.
The sorting unit 1C is provided with a sorting device 4 for sorting the object to be processed after the pod removal treatment.
The sorting device 4 includes a wall insert 40 as a blower for generating sorting wind, a rotary feeding device 41 having a drum-shaped outer peripheral surface that comes into contact with the object to be sorted, and the object to be processed after the pod removal process. A feeding device that grips the vicinity of the root of the foliage portion and feeds it backward is provided. This feeding device is also used by the portion of the feed chain 26 that sandwiches the root side of the pod-attached crop in the pod-removing device 3 and conveys it backward, which is located at the sorting point after exiting the pod-removing device 3.

As shown in FIGS. 4 and 5, in the sorting unit 1C, the wall insert 40 is arranged below the receiving conveyor 32 of the pod removal device 3. Then, between the end of the receiving conveyor 32 and the rotary feeding device 41, the rotary feeding device 41 is arranged at a position separated from the end of the receiving conveyor 32 on the rear side. That is, between the end of the receiving conveyor 32 and the rotary feeding device 41, dust having a small specific gravity, leaves having a large area, etc. float and are delivered to the rotary feeding device 41 side in a state of being blown by the wall insert 40 for comparison. An interval d1 suitable for the wind selection process is provided so that the pod portion having a large specific gravity falls.
At the lower part of the sorting unit 1C, on the rear side of the end of the receiving conveyor 32, at a position below the rotary feed device 41, among the objects to be sorted, the non-defective products whose removed objects have been removed by the wind sorting process. A lateral feed transport device 42 is provided for receiving a falling object such as a pod portion and transporting the falling object in the right lateral direction toward the recovery portion 1D provided on the right lateral side portion of the traveling machine body 1.
The start end side portion of the lateral feed transport device 42 and the left and right sides of the rotary feed device 41 are supported by a support frame 44 erected from the machine frame 10. The rotary feed device 41 is rotatably supported around a rotation axis P1 along a direction substantially orthogonal to the rearward feed direction of the object to be processed by the feed chain 26 in a plan view, and is shown in FIG. It is driven to rotate clockwise.

The upper portion of the outer peripheral surface of the rotary feed device 41 is provided at a height similar to the height of the sandwiching and transporting surface 26a of the feed chain 26. Since the rotary feed device 41 is driven so as to rotate clockwise in FIG. 5, the feed direction of the object to be processed on the upper part of the outer peripheral surface is the same as the feed direction to the rear side of the machine body by the feed chain 26. become. Therefore, the root side is gripped by the feed chain 26, and the foliage portion closer to the tip side than the gripping position is fed backward while being placed on the outer peripheral surface of the drum, so that the object to be processed in the sorting unit 1C can be smoothly fed. Easy to break.

Further, since the front portion of the outer peripheral surface of the rotary feed device 41 is arranged so as to exist at a position intersecting the blowing direction of the sorting wind by the wall insert 40, most of the sorting wind blown from the wall insert 40 is present. Once collides with the outer peripheral surface of the rotary feed device 41, and then diffuses. Therefore, it is easy to improve the sorting accuracy and the sorting efficiency by increasing the wind pressure of the sorting wind to some extent.
That is, if the conventional structure is such that the object to be processed is fed backward using a belt conveyor having a transport surface along the direction of the sorting wind of the wall insert 40, if the wind pressure of the sorting wind is made too large, the pods of good products are pods. There is a risk that even the part will be discharged by the wind. For this reason, the wind pressure of the sorting wind is set to be fairly low so as to blow off very light dust and leaf debris, and it is difficult to improve the sorting accuracy and sorting efficiency.
However, as described above, the sorting wind blown out from the wall insert 40 collides with the outer peripheral surface of the rotary feed device 41, so that even if the object to be processed once rides on the sorting wind, it has a large mass. If it is a pod portion or the like, when it collides with the outer peripheral surface of the rotary feed device 41, it stalls and falls on the lateral feed transfer device 42, and is transported toward the recovery unit 1D. Therefore, it is possible to improve the sorting accuracy and the sorting efficiency by increasing the wind pressure of the sorting wind to some extent.

The lateral feed transport device 42 is arranged in the front-rear direction on the rear side of the end of the receiving conveyor 32 and on the front side of the rear end of the rotary feed device 41. The front end of the lateral feed conveyor 42 is located near the end of the receiving conveyor 32 so that the object to be processed that has fallen from the end of the receiving conveyor 32 can be received. The rear end of the lateral feed transport device 42 is closer to the rear than the horizontal rotation axis P1 of the rotary feed device 41 and is located on the front side of the rear end position of the outer peripheral surface of the rotary feed device 41. That is, the rotary feed device 41 is arranged in a state in which the rotary feed device 41 is located behind the end of the receiving conveyor 32 and the rotary axis P1 is located on the front side of the rear end of the lateral feed transport device 42.

The outer peripheral surface of the rotary feed device 41 is formed in a polygonal shape (regular dodecagon in FIG. 5) in a directional view along the rotation axis P1, and the outer peripheral surface thereof is formed on the foliage portion of the object to be processed. A working tooth 6 is formed.
A large number of mounting holes 60 are formed in a flat portion of the outer peripheral surface of the rotary feed device 41, and a bolt member 61 is inserted into the mounting holes 60 to be tightened and fixed. The portion of the bolt member 61 that protrudes from the outer peripheral surface is used as the handle tooth 6.
The handle teeth 6 are planted so as to be scattered at a plurality of locations on the outer peripheral surface in the circumferential direction and in the axial direction along the rotation axis P1. The handle teeth 6 correspond to a side in which the planting interval in the circumferential direction of the outer peripheral surface or the direction along the rotation axis P1 is closer to the tip than the side closer to the root of the object to be processed gripped by the feed chain 26. It is provided so as to be denser as the portion is closed (see FIG. 4).
As shown in FIGS. 3 and 4, the mounting holes 60 are provided on the outer peripheral surface of the rotary feed device 41 in addition to the planting points of the bolt member 61. Therefore, it is possible to easily change the specifications such as changing the planting location of the bolt member 61 with respect to the mounting hole 60 and changing the number of planted bolt members 61.

[Recovery section]
The recovery unit 1D will be described.
The recovery unit 1D is a mounting base 5 provided along the front-rear direction of the machine frame 10 on the right side of the traveling machine body 1.
The mounting base 5 is configured in a box shape in which a vertical frame surrounds a belt-shaped bottom plate portion that is long in the front-rear direction and can receive and accommodate an object to be processed that is input from the end of the lateral feed transport device 42. Instead of such a box-shaped one, a structure having a long front-rear mounting table 5 and a roller conveyor (not shown) on the upper surface so that a plurality of collection containers (not shown) can be mounted. It may be.
