Abstract

PURPOSE:To easily change a reaping part to a state to pick-up and deliver culms heaped on a field by detachably attaching a raking rotor in front of a reaping apparatus. CONSTITUTION:A packer 10 to rake-up an object on the ground in front of a reaping apparatus and transfer the object to the back of the reaping apparatus is detachably attached to the front position of the reaping apparatus 7. The packer 10 is attached in the case of pick-up harvesting work and the culms raked in by the rotation of the packer around the lateral shaft center P are transferred toward an auger 8 with a cover guide 13 in such a manner as to avoid the reaping apparatus.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a means for harvesting mainly adzuki beans using a reaping harvester. It is also applicable to harvesting other crops such as soybeans.

0002

[Prior Art] Conventionally, methods of harvesting adzuki beans include drying the harvested grain rods by piling them up in the field by stacking them up on islands or stacking them on the ground, and then drying them by hand. The grain was then thrown into a threshing machine such as a harvester and threshed.

0003

[Problems to be Solved by the Invention] However, as described above, the work of picking up grain rods by hand and feeding them into the threshing machine requires continuous bending and stretching of the waist, which tends to cause fatigue for the worker. Therefore, some bean threshers are equipped with pick-up devices so that they can be picked up and threshed mechanically, but this results in an exaggerated device that imposes a large cost burden and requires a lot of work to attach and detach. There were complaints that the process was troublesome, and there was still room for improvement in the process of threshing the grain rods stacked in the field. The object of the present invention is to mechanize the above-mentioned threshing operation by a simple means.

0004

[Means for Solving the Problems] To achieve the above object, the present invention provides a height-adjustable raking reel for raking the tip side of a planted grain rod backward, a reaping device for cutting a planted grain rod, and a reaping device for cutting the planted grain rod. A reaping section, which is equipped with an auger that collects and sends out the harvested grain rods to the rear, and a conveyor that transports the reaped grain rods sent from the auger toward the threshing section of the traveling machine, is installed at the front of the traveling machine. This is related to the use of a reaping and harvesting machine (such as a combine harvester) that is connected in a row so that it can be raised and lowered, and the ground-mounted objects in front of the reaping device are raised at the front position of the reaping device and sent to the rear of the reaping device. A feature of this device is that the rake-up rotating body is provided in a removable manner.

[0005]

[Function] According to the above structure, the grain rods stacked in the field can be collected in the reaping section by the uptake action produced by the cooperation of the rake reel and the rake-up rotary body, and the By adjusting the elevation, it is possible to respond to changes in the height of the ground on which the drying grain rods are placed, making it possible to mechanize the entire harvesting process up to the subsequent threshing using existing reaping and harvesting machines. The only change to the machinery for this purpose is to removably install a rake-up rotating body in the front position of the reaping device, so a relatively simple replacement process can create a state suitable for normal reaping and harvesting work. It becomes possible to mutually change the state suitable for reaping and harvesting the grain rods stacked in the field. In the conventional method of manually feeding grain rods into an auger, it was difficult to keep a constant supply of grain rods, which could lead to clogging of the auger, clogging of the conveyor, or loss of threshing. In the present invention, since the grain rods are taken in by the rotating raking reel and the rake-up rotary body, the grain rods can be separated and thrown in evenly, and the causes of clogging and loss can be suppressed.

[0006]

[Effect of the invention] As a result, it is possible to thresh grain rods stacked in a field with an existing reaping and harvesting machine by simply replacing the structure by effectively utilizing the structure of the reaping section of the existing reaping and harvesting machine. As a result, the threshing work of the ground-drying grain rod can be mechanized, and the labor of the worker can be greatly reduced, while realizing a smooth transfer state of the reaped part using a means that can be easily changed at a low cost. We were able to provide a reaping and harvesting machine that can be used.

[0007]

Embodiments Below, embodiments of the present invention will be explained based on the drawings. As shown in FIG. 3, a reaping section 1 is installed in the front part of the machine so that it can be raised and lowered, and a driving section 2 is provided, as well as a threshing section 3 that threshes grain rods sent from the reaping section 1, and a sorting section. A full-rod feed type combine harvester for azuki beans is provided with a section (not shown) at the rear of the machine body, and is capable of traveling on a pair of left and right crawler traveling devices 5, 5. The reaping section 1 includes a height-adjustable raking reel 6 that scrapes the tip side of the planted grain rod backward, a reaping device 7 that cuts the planted grain rod, and a rear part that collects the harvested grain rod on the left side. and a conveyor 9 for transporting the harvested grain rods sent from the auger 8 toward the threshing section 3.

[0008] This combine harvester performs a normal reaping harvest operation in which planted grain rods are reaped and threshed, and a pick-up harvest operation in which a group of grain rods 4 erected on an island in a field are taken in and threshed as shown in Fig. 3. The reaping section 1 is configured to be able to change its state, and will be explained next. Figure 1, Figure 2
As shown in FIG. 2, a packer 10 (corresponding to a rake-up rotary body) is removably provided at a position in front of the reaping device 7 for lifting up objects placed on the ground in front of the reaping device 7 and sending them out to the rear of the reaping device. This packer 10 is composed of a large number of claw plates 12 having four claws 11 arranged side by side on the left and right when viewed from the side, and is rotatable around the left and right axis P, and the claws are located above the axis P. 11 is configured to drive and rotate in the rear direction, and a cover guide 13 is removably attached to guide the grain rods scraped by the packer 10 toward the auger 8 while preventing them from reaching the reaping device 7. . The cover guide 13 is constructed by forming a large number of slits 14 for rotating the claws 11 in a substantially U-shaped plate facing backward, and is provided so as to enclose the packer 10 and the reaping device 7. The packer 10 receives driving force from a chain interlocking mechanism A that interlocks the conveyor 9 and the auger 8. In other words,
By interlocking the tension sprocket 15 of the chain interlocking mechanism A and the packer shaft 16 with a chain 17, the packer 10 is driven and rotated in a direction opposite to the direction of rotation of the auger 8.

[Another embodiment] As shown in FIG.
A rotary cylinder 10 provided with an in/out finger 19 that rotates around a support shaft 18 that is offset from the rotation cylinder 6 may be attached to the front position of the reaping device 7. These rotary cylinders 10 and packers 10 are collectively defined as a rake-up rotary body 10. Moreover, as a drive means for the scraping rotary body 10, a structure using a hydraulic motor or an electric motor can be considered.

[0010]Although reference numerals are written in the claims for convenience of comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
