Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shell culm nip transfer device for a combine, which includes, for example, a feed chain and a nip rod.

Conventionally, a technology in which a noid chain was extended to the rear end of the fourth gutter that conveys waste straw (for example, Japanese Utility Model Application Publication No. 52-50963), and a culm of the waste straw conveying belt was installed on the sandwich plate rod of the feed chain. Technology for installing guides in series (e.g. Jikko Sho 39-3)
Publication No. 3687).

However, in the prior art, the waste straw was conveyed in a substantially horizontal position, so that the kernels with stems did not fall off completely, and it was difficult to efficiently collect them.

The present invention solves the above-mentioned drawbacks, and includes a combine shell culm nip transfer device consisting of a feed chain and a nip rod, in which the nip rod has a plurality of short nip plates and a single long nip rod. A plurality of short clamping plates are independently pressed against the shell culm conveying part on the starting end side of the feed chain along the handling chamber, and the fourth gutter into which the shell culm tip side is inserted downward. A single long nip plate is pressed against the straw conveying part on the end side of the feed chain to be followed, and the grains with stems of the straw with the tip side facing downward can easily fall into the fourth gutter. It is possible to improve the recovery efficiency of grains with stems compared to the conventional method, and the straw that holds the stock by the long sandwich plate and the feed chain can be bent into a shape and inserted into the fourth gutter, It is an object of the present invention to provide a device for transferring shell culms of a combine harvester in which the structure of the culms is simplified by bending the waste straw, thereby preventing the culms from falling off.
