Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention is a mobile threshing machine for threshing by appropriately moving a machine body by a steering operation to stop the machine and supplying grain culms to a supply port in this stopped state to thresh. The present invention relates to a grain culm feeder.

(B) Conventional Technology Conventionally, there is already known a moving thresher in which a supply base is rotated upward when traveling on a road or the like to approach a thresher, and the threshing device is coupled in that state.

(C) Problems to be devised and solved In the known mobile threshing machine, the supply stand is erected around its base, and when the machine is run while being locked to the threshing device by the connecting tool, vibration is caused by the vibration. The connector was sometimes detached, and the supply base and its mounting part were damaged, which was extremely dangerous.

(D) Means for Solving the Problems The present invention mounts an upper chain type automatic thresher on a machine base having a traveling device, and pivots the base of the supply base on the outside of the supply port side so that the base can be undulated. Then, the connecting tool is interposed between the supply table and the automatic threshing machine rotated to the supply port side, and the base of the supply table is pivotally mounted with an arm whose tip side tilts on the starting end of the pinching rail. When the base of the supply base and the arm are rotated to the storage position by rotating the supply base upwards, the arm is pushed down and linked to compress the ammunition of the sandwiching rail so that the sandwiching rail can be folded and stored. Keep the springs in compression,
As a result, the above-mentioned problem was solved by preventing the connecting tool from coming off.

(E) Action When performing threshing work, the supply base is extended to the side, and when storing it, it is rotated up about the base to stand up.
When tilting a little to the threshing device side in this state, the base of the supply table lowers and pivots the arm, and the tip of the arm rests on the start end of the pinch rail and pushes it down, so it holds the pinch rail. The spring is compressed, and in this state, the supply table and the threshing device are connected by the connecting tool.

When the machine is run in this state, the connecting tool connecting the supply table to the threshing device always receives a tensile force,
Even if the machine body vibrates during traveling, the connecting tool does not come off.
