DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing apparatus for threshing grain culm, and is used for a threshing machine such as a combine.

[0002]

2. Description of the Related Art In order to inspect and clean an airframe, there is a configuration in which a mowing section and a feed chain are detached from the airframe.

[0003]

However, it is inconvenient to handle the mowing part and the feed chain by detaching the mowing part and the feed chain from the machine body. Further, the mowing part and the feed chain are constructed so that only the mowing part is moved to open the front part of the machine body. When only the feed chain is opened, the opening portion is limited, and there is a problem that maintenance and management of the machine is troublesome.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has taken the following technical means. That is, in the first invention, the operating unit 13 is provided on one side of the machine, and the threshing machine 5 including the feed chain 4 is provided on one side of the handling room 3 on the other side of the machine. In front of 5, weeding device 6a, raising device 6 that causes grain culm
b, a cutting unit 6 comprising a cutting device 6c for cutting the culms after the raising and a conveying device 6d for conveying the culms after cutting to the rear, and the feed chain 4 is provided by the feed chain.
4 can be moved outward centering on the vertical axis 17 provided on the front side.
An operator stands between the threshing machine 5 and the feed chain 4.
The cutting part 6 constitutes a space part which can be entered.
Centered on one of the vertical axes provided on the right or left side of the taking part 6
To the right or left side to allow workers

To the combine according to the first invention.

[0006]

When the machine is advanced and the work is started, the culm in the field is weeded by the weeding device 6a, then raised by the raising device 6b, and the root of the plant is cut off by the reaping device 6c. Then, the harvested grain culm is taken over by the conveying device 6d and conveyed rearward, and the threshing machine 5 threshes its tip. For example, in order to inspect and clean the machine body before or after the start of such a harvesting operation, the cutting unit 6 and the feed chain 4 are rotated about the vertical axis . Then,
An operator enters between the feed chain 4 and the threshing machine 5
The space part which can do it is constituted.

Further , the reaper 6 rotates leftward or rightward.

The space part which can be constructed.

[0008]

According to the first invention, the feed chain 4 and the threshing machine 5
There is a space between them that allows workers to enter
The maintenance pipe of the feed chain 4 and the threshing machine 5
Can be easily implemented. In addition, the cutting unit 6 and the threshing machine 5
There is a space where workers can enter
Therefore, maintenance management of the rear part of the mowing part 6 and the front part of the threshing machine 5
Can be easily implemented.

In the second invention, the feed chain 4 is rotated.
The vertical axis 17 that rotates the cutting unit 6 is the same axis as the vertical axis 17
Therefore, the support structure can be simplified. That is, the vertical axis 17
It is not necessary to provide two places, so no extra space is required
And the number of parts decreases.

[0010]
