[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine threshing apparatus in which a feed chain is provided on the left side of a threshing unit in which a handling cylinder is provided.

[0002]

2. Description of the Related Art Conventionally, there has been a technique in which a feed chain is horizontally rotated about a rear fulcrum shaft to separate the feed chain from a threshing unit and exchange a crimp net.

[0003]

In the above prior art, the net holding plate connected to the left edge of the crimping net was attached to the feed chain side, and the feed chain was opened with the threshing machine housing left side plate fixed. When the threshing amount is large, the culm is pressed in the outer peripheral direction by the handling cylinder,
The mesh metal holding plate swells outward and the feed chain is likely to vibrate, and a gap is formed in the threshing side plate, causing dust to leak. The left side of the machine is closed by the left side panel, the crimp net entry / exit space is narrow and the work is troublesome, and the opening to clean the upper surface of the swing sorter needs to be formed on the left side of the threshing machine. There were top and structural problems.

[0004]

SUMMARY OF THE INVENTION However, the present invention provides a combine threshing apparatus in which a feed chain is detachably attached to a left side of a threshing machine casing about a fulcrum shaft.
Net holding plate that forms the side is integrally connected to the left end of the crimp net
In addition, a left side plate for opening an opening of approximately the same front and rear length as the crimp net on the left side of the threshing machine housing is attached to the feed chain side, and since the left side plate is opened integrally with the feed chain, the crimp net enters and exits. The space can be made larger than before so that replacement work and the like can be easily performed, and the upper surface of the swing sorting board can be easily cleaned from the opening from which the left side plate has been removed. Also, place the mesh holding plate on the left side plate side.
Because it is not installed in the feed chain, vibration of the feed chain can be prevented and dust
Create a gap in the left side plate that causes leakage, etc.
Can be prevented.
