Description

[Detailed Description of the Invention] In the present invention, a sorting section is disposed at the bottom of the threshing section, and a processing device for waste straw from the threshing section is installed at the rear of the threshing section, rather than the sorting section. It is a combine harvester that protrudes rearward and is located above the sorting section, so that cleaning and maintenance such as removing residual grain and straw from the threshing section and sorting section can be easily performed. The present invention relates to one in which the threshing section is configured to be swingably switched to a position in which the upper part of the sorting section is opened.

In conventional combines of this kind, the threshing section is configured to switch to a position in which the upper part of the sorting section is opened by swinging around the front and back axis at or near the upper left and right sides of the sorting section. However, when using this method, the heavy threshing section equipped with a handling barrel, etc. must be swung to lift it against the entire weight of the threshing section, so it takes a lot of work to open the sorting section upward. There was a drawback that required a lot of effort.

The purpose of the present invention is to overcome these conventional drawbacks.

This invention focuses on the fact that the waste straw processing device connected to the rear of the threshing section has a considerable weight, and that there is a dead space below the waste straw processing device at the rear of the sorting section. The characteristic configuration of the combine harvester according to the present invention, which was taken to achieve the above object, is that the threshing section and the waste straw processing device perform the sorting by swinging around the horizontal axis at or near the rear upper part of the sorting section. The structure is configured such that the upper part of the part can be freely switched to an open position.

The effects of the characteristic configuration of the present invention described above are as follows.

(1) The threshing section and the waste straw processing device are switched to a posture in which the upper part of the sorting section is opened by swinging the threshing section and the waste straw processing device together around the horizontal axis using the dead space as the swing space of the waste straw processing device. , the weight of the waste straw processing device can be used as the swinging force to the open position.

(2) When the threshing section and the waste straw processing device are swung to the open position, the waste straw processing device comes close to or comes into contact with the rear of the sorting section. Even if the open posture is unexpectedly released, the threshing section and the waste straw processing device can be prevented from swinging backwards, that is, from falling down.

The effects of the above action are as follows.

[] By the action of (1) above, the threshing section and the waste straw processing device can be easily operated without using a special actuator or balance weight, and
It can be easily swung into the open position, thereby greatly improving the workability of cleaning and maintenance of the threshing section and sorting section.

[] By the effect of (2) above, safety during cleaning and maintenance can be improved.

Hereinafter, embodiments of the configuration of the present invention will be described based on the drawings.

A threshing device having a structure in which a sorting section 2 is arranged below the threshing section 1, a grain bagging hopper 3, and a riding driving section 4 are mounted on a body frame 6 equipped with a crawler traveling device 5, and the above-mentioned Airframe frame 6
A reaping pre-processing device 7 for reaping the planted grain culm and conveying it to the threshing section 1 is connected to the front part of the threshing section 1, and a processing device for processing waste straw from the threshing section 1 is installed at the rear of the threshing section 1. 8 are connected in a row so as to protrude rearward from the sorting section 2 and are located above the sorting section 2, thereby forming a combine harvester.

The threshing section 1 includes a handling cylinder 1A and a feed chain 1B.

The sorting section 2 includes a swinging sorting plate 2A, a winnowing machine for generating a sorting airflow 2B, a No. 1 collected grain carrying screw 2C, and a No. 2 collected grain conveying screw 2D.

The reaping pre-processing section 7 is configured to be able to move up and down, and to be able to move forward and away from the machine frame 6.

The waste straw processing device 8 includes a waste straw conveying device 8A using a chain and a processing device main body 8B, and examples of the processing device main body 8B include a binding machine, a cutter, and the like.

Thus, the threshing section 1 and the waste straw processing device 8
is structured such that it can be freely switched to an upright position in which the upper part of the sorting part 2 is opened by integrally swinging the rear upper part of the sorting part 2 upward around the horizontal axis X, and the sorting part 2 When the swing sorting plate 2A is disconnected from the main body via the swing support link 2a at its front end, it swings upward around the swing support shaft 2b at its rear end, thereby removing both screws 2.
The sorting section 2 with C and 2D is configured to be switchable to an upright position in which the bottom part is opened upward.

According to the configuration of the above embodiment, the weight of the waste straw processing device 8 can be used as a force for swinging the threshing section 1 and the waste straw processing device 8 to the upright position. You can easily switch to

To explain the cleaning procedure, move the reaping pre-processing section 7 forward to release the interference of the reaping pre-processing section 7 with the feed chain 1B, and then rock the threshing section 1 and the waste straw processing device 8 to an upright position. The threshing section 1 and the swinging sorting plate 2A are then moved to clean the threshing section 1 and the swinging sorting plate 2A, and then the swinging sorting board 2A is swung into an upright position to clean the bottom of the sorting section 2.

In the drawings, the feed chain 1B is also configured to integrally swing upward, but the feed chain 1B may be configured in a fixed manner so as not to integrally pivot upward.
