Description

[Technical field]

[0001] The present invention relates to a soybean harvester. [Background technology]

[0002] Conventionally, as an edamame harvester, for example, the edamame harvester described in Patent Document 1 is known. The conventional edamame harvester includes an extraction and conveying device (referred to in the literature as "extraction and conveying device

[11] ") that extracts edamame from a field and conveys them backward, and a soil removing device (referred to in the literature as "soil removing device

[50] ") that is provided midway in the conveying direction of the extraction and conveying device and removes mud adhering to the roots of the edamame being conveyed by the extraction and conveying device. The soil removing device is configured to rotate around a rotation axis extending along the left-right direction of the machine body to come into contact with the roots of the edamame, and includes left and right rotating bodies (referred to in the literature as "soil removing tools

[51] ") that are provided facing each other in the left-right direction of the machine body, sandwiching the center of the extraction and conveying device in the left-right direction of the machine body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-105018 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a conventional soybean harvester, a space is formed between the left rotor and the right rotor into which the roots of the soybeans can enter. However, if the lump of mud (soil lump) adhering to the roots of the soybeans is large, there is a risk that the roots of the soybeans will not be able to enter the space between the left rotor and the right rotor. For this reason, there is room for improvement in the conventional soybean harvester in terms of effectively removing mud adhering to the roots of the soybeans during transport by the extraction transport device.

[0005] In view of the above situation, there is a demand for a soybean harvester that can effectively remove mud adhering to the roots of soybeans while they are being transported by the pulling-out and transporting device. [Means for solving the problem]

[0006] The present invention is characterized by comprising an extracting and conveying device that extracts soybeans from a field and conveys them backward, and a soil removing device that is provided midway in the conveying direction of the extracting and conveying device and removes mud adhering to the roots of the soybeans being conveyed by the extracting and conveying device, the soil removing device being configured to rotate about a rotation axis extending along the left-right direction of the machine body to contact the roots of the soybeans, and having left and right rotating bodies provided in a state facing each other in the left-right direction of the machine body across the center of the left-right direction of the machine body of the extracting and conveying device, the rotating bodies having a rotating shaft that can rotate about the rotation axis, a base member supported by the rotating shaft in a state that allows it to rotate integrally with the rotating shaft, and a plurality of claws that are supported by the base member and extend radially from the base member toward the center so as to be away from the rotation axis as they approach the center. The left rotating body and the right rotating body are configured to be rotatably driven in opposite directions around the rotation axis. The reason is that

[0007] According to this characteristic configuration, the claws are inclined away from the axis of rotation as they move toward the center of the body of the extraction and conveying device in the left-right direction. This ensures that a wide space is secured between the left-side rotating body and the right-side rotating body into which the roots of the soybeans can enter. Furthermore, the claws act on the mud over a wide range in the direction of extension of the claws. This makes it possible to effectively remove mud adhering to the roots of the soybeans being conveyed by the extraction and conveying device. Furthermore, because a wide space is secured as described above, the roots of the soybeans can smoothly come out of the space after the soil has been removed. In addition, with this characteristic configuration, one rotating body rotates in the forward direction while the other rotating body rotates in the opposite direction, so that the mud lumps (soil lumps) do not climb over the left and right rotating bodies, and the claws can reliably act on the soil lumps.

[0008] Furthermore, in the present invention, it is preferable that the multiple claws on the left-side rotating body and the multiple claws on the right-side rotating body are arranged in a state where their positions do not overlap with each other in the direction of the rotation axis, and that a space is formed between the left-side rotating body and the right-side rotating body into which the roots of the edamame beans enter during transport by the extraction and transporting device.

[0009] According to this characteristic configuration, a larger space is secured between the left rotor and the right rotor into which the roots of the soybeans can fit. This allows the claws to reliably act on the mud with the roots of the soybeans in the space.

[0010]

[0011]

[0012] Further, in the present invention, The present invention comprises an extracting and conveying device which extracts soybeans from a field and conveys them backward, and a soil removing device which is provided midway in the conveying direction of the extracting and conveying device and removes mud adhering to the roots of the soybeans being conveyed by the extracting and conveying device, the soil removing device being configured to rotate about a rotation axis extending along the left-right direction of the machine body to come into contact with the roots of the soybeans, and having left and right rotating bodies which are provided facing each other in the left-right direction of the machine body across the center of the left-right direction of the machine body of the extracting and conveying device, the rotating bodies having a rotating shaft which can rotate about the rotation axis, a base member which is supported by the rotating shaft in a state in which it can rotate integrally with the rotating shaft, and a plurality of claws which are supported by the base member and extend radially from the base member toward the center so as to be more distant from the rotation axis as they approach the center, The soil removing device has left and right side walls that support the left and right rotating bodies, respectively, and the left base member is provided adjacent to the left side wall, and the right base member is provided adjacent to the right side wall. R It is preferable that:

[0013] According to this characteristic configuration, The claws are inclined with respect to the axis of rotation so that they move away from the axis of rotation as they approach the center of the body of the extraction and conveying device in the left-right direction. This ensures that a wide space is secured between the left-hand rotor and the right-hand rotor into which the roots of the soybeans can enter. The claws also act on the mud over a wide range in the direction of extension of the claws. This makes it possible to effectively remove mud adhering to the roots of the soybeans being conveyed by the extraction and conveying device. Furthermore, because a wide space is secured as described above, the roots of the soybeans can smoothly come out of the space after the soil has been removed. In addition, according to this characteristic configuration, the distance between the left and right base members in the direction of the rotation axis is wide, which makes it possible to secure a larger space between the left and right rotors for the roots of the soybeans to enter.

[0014] Furthermore, in the present invention, it is preferable that the base member is configured by a disk-shaped plate-like member.

[0015] According to this characteristic configuration, since there are no corners on the outer periphery of the base member, the roots of soybeans are less likely to get caught on the base member. Furthermore, in the present invention, it is preferable that the base member has a plurality of support portions that are provided so as to extend radially outward from the rotation axis and that support the plurality of claws, respectively. According to this characteristic configuration, the base member is provided with support portions corresponding to the number of claws, so that the base member can be configured compactly.

[0016] Further, in the present invention,The present invention comprises an extracting and conveying device which extracts soybeans from a field and conveys them backward, and a soil removing device which is provided midway in the conveying direction of the extracting and conveying device and removes mud adhering to the roots of the soybeans being conveyed by the extracting and conveying device, the soil removing device being configured to rotate about a rotation axis extending along the left-right direction of the machine body to contact the roots of the soybeans, and having left and right rotating bodies provided in a state facing each other in the left-right direction of the machine body across the center of the left-right direction of the machine body of the extracting and conveying device, the rotating bodies having a rotating shaft which can rotate about the rotation axis, a base member which is supported by the rotating shaft in a state in which it can rotate integrally with the rotating shaft, and a plurality of claws which are supported by the base member and extend radially from the base member toward the center so as to be more distant from the rotation axis as they approach the center, the base member being configured as a disk-shaped plate-shaped member, It is preferable that a rising portion is provided on the outer periphery of the base member, the rising portion rising from the outer periphery of the base member to a side opposite to the center in the direction of the rotation axis.

[0017] According to this characteristic configuration, The claws are inclined with respect to the rotation axis so that they move away from the rotation axis as they approach the center of the body of the extraction and conveying device in the left-right direction. This ensures that a wide space is secured between the left-hand rotor and the right-hand rotor into which the roots of the soybeans can enter. The claws also act on the mud over a wide range in the direction of extension of the claws. This makes it possible to effectively remove mud adhering to the roots of the soybeans being conveyed by the extraction and conveying device. Furthermore, because a wide space is secured as described above, the roots of the soybeans can smoothly come out of the space after the soil has been removed. Furthermore, according to this characteristic configuration, since there are no corners on the outer periphery of the base member, the roots of the soybeans are less likely to get caught on the base member. Furthermore, According to this characteristic configuration, the periphery of the rotating shaft is covered from the radially outer direction by the raised portion, which makes it difficult for the roots of the soybeans to become wrapped around the rotating shaft.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] An embodiment of the present invention will be described with reference to the drawings. In the following description, the direction of the arrow F is the "front side of the aircraft", the direction of the arrow B is the "rear side of the aircraft", the direction of the arrow L is the "left side of the aircraft", and the direction of the arrow R is the "right side of the aircraft".

[0022] [Overall configuration of the soybean harvester] A soybean harvester is shown in Figures 1 and 2. This harvester is equipped with a traveling body 1, a driving section 2 on which a driver sits, a hulling device 3 that hulls the soybeans E, an extraction and transporting device 4 that extracts the soybeans E from the field and transports them to the hulling device 3, a soil removing device A that removes mud M adhering to the roots of the soybeans E being transported by the extraction and transporting device 4, a position changing device 5 that changes the position of the soybeans E to a lying position, and a recovery section 6 that recovers the pods e.

[0023] The traveling body 1 comprises a crawler traveling device 7 and a body frame 8 supported by the crawler traveling device 7. The driving section 2 is provided at one side (right side) in the left-right direction of the body at the front of the traveling body 1. The pulling-out and conveying device 4 is provided at the other side (left side) in the left-right direction of the body at the front of the traveling body 1. The husk removal device 3 is provided behind the pulling-out and conveying device 4. The recovery section 6 is provided to the right of the driving section 2 and the husk removal device 3.

[0024] As the traveling body 1 advances, the soybeans E in the field are pulled out by the pulling-out and conveying device 4 and conveyed toward the husking device 3. The soybeans E from the pulling-out and conveying device 4 are then changed to a lying position by the position changing device 5 and handed over from the pulling-out and conveying device 4 to the husking device 3. After the soybeans E have been husked by the husking device 3, the pods e are collected in the collection section 6, while the branches and leaf waste are discharged from the rear end of the husking device 3 into the field.

[0025] The pulling-out conveying device 4 is provided in front of the husking device 3 so as to be able to swing up and down with respect to the husking device 3. The pulling-out conveying device 4 is provided in a state inclined downward toward the front. The pulling-out conveying device 4 is configured to be able to swing up and down around a swing axis X1 extending along the left-right direction of the machine body. A hydraulic cylinder 9 for swinging the pulling-out conveying device 4 up and down is provided between the pulling-out conveying device 4 and the machine body frame 8. The pulling-out conveying device 4 includes left and right first conveying belts 10 and left and right second conveying belts 11 that pull out the crops from the field and convey them backward. The first conveying belt 10 is wound around driven pulleys 12 and 13. The second conveying belt 11 is wound around driven pulleys 14 and driving pulley 15. When power is transmitted to the drive pulley 15, the second conveyor belt 11 is driven to be conveyed via the driven pulley 14 and the drive pulley 15, and the first conveyor belt 10 is driven to be conveyed via the driven pulleys 12 and 13.

[0026] As the traveling body 1 moves forward, the soybeans E in the field are pulled out by the left and right first conveyor belts 10 and transported backwards in an upright position. The soybeans E are then handed over from the left and right first conveyor belts 10 to the left and right second conveyor belts 11, and the soybeans E are transported in an upright position towards the hulling device 3 by the left and right second conveyor belts 11. In Figure 2, the center of the pulling-out conveyor device 4 (the left and right first conveyor belts 10 and the left and right second conveyor belts 11) in the left-right direction of the body is indicated by C. The soybeans E pulled out of the field are transported backwards in an upright position through the center C.

[0027] The husk shelling device 3 is equipped with a feed chain 16, upper and lower first husk shelling rollers 18, and upper and lower second husk shelling rollers 19. The position changing device 5 is equipped with a large number of claws 5a that engage with the edamame E. The edamame E from the pulling-out and conveying device 4 are handed over to the feed chain 16 while being changed to a sideways position by the position changing device 5. At that time, the claws 5a engage with the edamame E from the pulling-out and conveying device 4, changing the position of the edamame E to a sideways position. The edamame E are then conveyed backwards by the feed chain 16. Then, as the edamame E is transported by the feed chain 16, it is sandwiched between the upper first pod-threshing roller 18 and the lower first pod-threshing roller 18, and between the upper second pod-threshing roller 19 and the lower second pod-threshing roller 19, and the upper and lower first pod-threshing rollers 18 and the upper and lower second pod-threshing rollers 19 are rotated, causing the pods e to be plucked from the branches.
