Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applied to a glue conveying device a which clamps and conveys the root part of a threshing culm at a threshing opening.

Mobile and stationary threshing machines and combine threshing machines have a shell culm conveying device that clamps and transports the root part of the threshing grain fJP, and handles the tip of the shell culm that is mounted on a shaft in a handling room and transported. It is equipped with a handling trunk for threshing. Among these, the culm conveyance device is composed of an endless conveyor belt stretched along the handling chamber, and a clamp rod supported along the running end of the conveyor belt and biased toward the endless belt by a spring member. .

However, conventionally, the endless belt is attached to the threshing frame, but the lever is attached to the handle barrel cover that can be opened and closed to cover the upper part of the handle barrel, or to the culm cover that is integrated with the handle barrel cover, which makes cleaning and maintenance easier. Even if you do not open or close only the handling body cover for such reasons, you will have to open and close the handling body cover each time while the extremely heavy clamping rod and its attached clamping springs are attached9, which requires an extremely large amount of effort. In addition to this, there was also the disadvantage that threshing efficiency decreased due to neglect of cleaning.

The present invention has been made with the above points in mind, and provides a handling trunk cover that can freely open and close the pressing body that supports the endless belt for transporting the husk on the side of the threshing frame body, presses it, and releases it. To provide a shell culm conveying device for a thresher that is fixed to the side, thereby making it easy to open and close a handling barrel cover to reduce labor. -1 Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

2 presses the gripping guide 13 downward against the elastic force of the clamping spring 16, and presses the gripping rod 15 against the endless band T side.

In the threshing machine configured as described above, the culm whose root portion is fed between the arcuate tip of the clamping rod 15 and the endless band 1 is held between the clamping rod 15 and the endless band 7. The kernels are conveyed in the direction of arrow A, and the tips are handled and threshed by the handling teeth 5 of the barrel 6. In this case, since the handling cylinder cover 17 is locked with the closed stopper 19, the pressing bodies 21, 2
