A technique is shown in which the rear pod removal device is used to remove the pods.
According to this structure, since the planted green soybeans are pulled out together with the stems and transported backward to the field, it is useful because it can be harvested without leaving stumps and the like, and it is easy to manage the field after pulling out.

However, in the structure described in Patent Document 1, the endless band chain provided at the lower part of the front part of the machine body makes it easy to grip the position of the edamame stalk near the lower end side and pull out the edamame well. However, since the endless band chain is too close to the ground, a pair of left and right ground plates are required to prevent it from entering the soil, and mud and pebbles may get caught in the endless band chain and damage it. There was a problem such as.
In addition, since the subsequent endless flexible band grips the stem part at a position farther from the lower end than the gripping position with the endless band chain, the leaf stem part and the pod part located near the root of the edamame are used. , There was a problem that it was difficult to insert it into the back of the pod removal device.

Further, in the structure described in Patent Document 1, since the power transmission structure to the endless band chain at the front portion of the airframe is provided separately from the drive structure of the subsequent endless flexible band, the power transmission structure is complicated. There is also a problem in that it tends to increase the weight of the aircraft and the weight of the aircraft.

According to the present invention, the pod-attached crop can be inserted into the inner part of the pod-removing device while the tip side of the holding and transporting device for pulling out the pod-loaded crop and transporting it backward can be extracted without being extremely close to the ground. It is intended to provide a podded crop harvester that is easy to use and has a simplified power transmission structure.

The rear transport device 2 is a long pinch transport device 20 that pulls out the stem portion of the crop in the field and transports it rearward and upward, and a transport end portion of the pinch transport device 20 that lays down the upper part of the crop. It is provided with a sideways supply device 24 that changes its posture to and delivers it to the subsequent pod removal device 3. These sandwiching and transporting devices 20 and the sideways feeding device 24 are arranged on the left side of the traveling machine body 1.

[Pinch transport device]
The pinch transfer device 20 includes a pair of left and right endless rotating belts 21 and 21 in a rear-upward tilting posture in which the transfer start end is located near the ground and the transfer end side is located at a higher level on the rear side of the machine body. The endless rotating belts 21 and 21 are driven by being wound around a drive pulley 20A, a relay pulley 20B, and a driven pulley 20C. Between the left and right endless rotating belts 21 and 21, a crop transport path r1 that sandwiches and transports the stem portion of the pod-mounted crop is formed along the traveling direction of the machine body.

As shown in FIGS. 1, 2 and 5, 6, the pair of left and right endless rotating belts 21 and 21 have the front rotating belts 21a and 21a located on the front side of the relay pulley 20B and the rear side. It is composed of a combination of the rear rotation belts 21b and 21b located at.
The relay pulley 20B includes upper and lower two-stage pulley portions 20Ba and 20Bb that rotate integrally on the same axis. Of the relay pulley 20B, the front rotation belts 21a and 21a are wound around the pulley portion 20Ba on the upper stage side and the driven pulley 20C. Of the relay pulley 20B, the rear rotation belts 21b and 21b are wound around the lower pulley portion 20Bb and the drive pulley 20A.

Therefore, when the stalks of the crops in the field are sandwiched between the pair of left and right endless rotating belts 21 and 21 and then pulled out and transported upward and backward, the stalks of the crops are changed during the transportation. That is, the lower side of the crop stem portion sandwiched between the front rotating belts 21a and 21a on the front side of the relay pulley 20B is sandwiched by the rear rotating belts 21b and 21b on the rear side of the relay pulley 20B. Since the crop is transported, the holding portion of the podged crop is closer to the root of the crop in the rear rotating belts 21b and 21b than in the sandwiching location of the front rotating belts 21a and 21a.
If the crop is inserted into the pod removal device 3 in this state, the tip side of the pinching point is inserted into the pod removal device 3, and almost the entire crop is inserted into the pod removal device 3 near the root. It is easy to remove the pods of existing crops with little loss.

The sandwiching and conveying device 20 is provided with a belt support frame 22 that supports a pair of left and right endless rotating belts 21 and 21.
The belt support frame 22 includes a right frame 22R that supports the right endless rotating belts 21 and 21, and a left frame 22L that supports the left endless rotating belts 21 and 21.

A support portion 23c is provided on the lateral side portion of the left side plate portion 23a of the lower connecting member 23 to support the front end portion of the round bar-shaped uncut side weed rod 15 in a state of being inserted into the hole portion. That is, the lower connecting member 23 on the front side also serves as a supporting means for supporting the front end portion of the uncut side weed rod 15.

Further, as shown in FIG. 5, the connecting body 23b located at the lower end of the lower connecting member 23 on the front side is a crawler when the front end of the sandwiching and transporting device 20 is positioned low enough to be in contact with the field scene. It is located on substantially the same line as the virtual line segment GL connecting the ground plane of the traveling device 11 of the type and the front end portion of the sandwiching carrier 20.
The lower end edge of the driven pulley 20C around which the endless rotating belts 21 and 21 are wound is also substantially the same as the virtual line segment GL connecting the ground contact surface of the crawler type traveling device 11 and the front end portion of the pinching transfer device 20. It is located on the line.
Therefore, when the front end portion of the sandwiching and transporting device 20 is positioned low enough to be in contact with the field scene, the connecting body 23b located at the lower end portion of the lower connecting member 23 on the front side also comes into contact with the field scene. It is 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 and the lower end edge portion of the driven pulley 20C are about to plunge into the soil.

Among the lower connecting members 23, the lower connecting member 23 located on the rear side of the relay pulley 20B is a side plate portion 23a extending downward from the right frame body 22R and the left frame body 22L, and the left and right side plate portions 23a thereof. The square pipe-shaped connecting body 23b that connects the two is integrated, and is formed in a U shape that bypasses the lower side of the crop transport path r1 in the front-rear direction view.
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 elevating cylinder 16 for raising and lowering the front end side of the sandwiching and conveying device 20. That is, the lower connecting member 23 on the rear side also serves as a mounting portion for the front end side of the elevating 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 path r1. Therefore, the front and rear lower connecting members 23 also serve as means for reinforcing the vicinity of the attachment portion of the relay pulley 20B.

Of the front rotating belts 21a and 21a wound over the relay pulley 20B on the upper stage side and the driven pulley 20C, the front rotating belts 21a and 21a are on the back side of the portion facing the crop transport path r1. However, a plurality of guide wheel bodies 21c for suppressing the movement to the side away from the crop transport path r1 are provided.
Further, of the post-rotating belts 21b and 21b wound over the relay pulley 20B, the lower pulley portion 20Bb, and the drive pulley 20A, the rear-rotating belts 21b and 21b are rear-rotated to the back side of the portion facing the crop transport path r1. A plurality of guide wheels 21d for suppressing the belts 21b and 21b from moving to the side away from the crop transport path r1 are provided.

As shown in FIG. 6, among the guide wheel bodies 21c and 21d described above, the arrangement pitch P1 of the plurality of guide wheel bodies 21c provided on the front rotating belts 21a and 21a is set on the rear rotating belts 21b and 21b. It is set shorter than the arrangement pitch P2 of the plurality of provided guide wheel bodies 21d.
Further, in the endless rotating belt 21, the pinching pressure in the crop transport path r1 in the front rotating belts 21a and 21a is set to be slightly higher than the pinching pressure in the crop transport path r1 in the rear rotating belts 21b and 21b. It is done.
When the pinching pressure is slightly increased and the stems of the crops are strongly gripped by the front rotating belts 21a and 21a to pull out the crop, the front rotating belts 21a and 21a exert the reaction force of the crop to be pinched. The phenomenon of receiving and deforming to the side away from the crop transport path r1 is suppressed by shortening the arrangement pitch P1 of the plurality of guide wheels 21c.
