Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine threshing device for threshing grain culms cut by a cutting section.

[0002]

2. Description of the Related Art Conventionally, when the side of the threshing section is opened to perform maintenance and inspection of the handling room and the handling barrel and replacement of the crimp net,
I had to remove the feed chain.

[0003]

The above-mentioned prior art is extremely inefficient because it requires a troublesome work for removing the feed chain, and when the feed chain is provided freely on the side of the threshing unit, when it is opened, There has been a problem that the end of the feed chain opposite to the horizontal rotation fulcrum is easily deformed by its own weight lowering.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, in a combine threshing device in which a feed chain for conveying threshing culms is provided to the side of the threshing section so as to be openable, the grain culm conveying side of the feed chain is supported. The rail member and the rail member supporting the non-conveying side of the feed chain are integrally connected, and the rotation fulcrum side of the feed chain is connected to the threshing main body side through a vertically long pillar. The rail member on the transport side of the chain can be reinforced by the rail member on the non-transport side, the feed chain support strength can be easily secured, and the weight of the feed chain when opened can be reliably supported by the vertically long pillars. It can be safely handled by preventing deformation and damage due to.
