THE INVENTION Problems to be Solved] something like this public
However, in a threshing machine in which threshing is performed by a conventional handling room and a processing chamber, the amount of grain culm supplied to the threshing machine becomes proportional to the processing amount in the processing chamber.
Focusing on this point, the present invention has been made for the purpose of automatically adjusting and controlling the processing capacity in the processing chamber according to the fluctuation of the supply amount of the grain stalk and eliminating the loss due to the discharge of the grain outside the machine.

[0004]

Therefore SUMMARY OF THE INVENTION, on the achieving the above object that the present invention, threshing chamber and, extending rearwardly from the side of Okuchiri port opening to discharge稈側of the threshing chamber And from the dust outlet
In threshing machine for threshing process the culms by a processing chamber for processing the raw material, automatically increases or decreases the rotational speed of the processing drum being furnished to the processing chamber in accordance with the culms supply amount supplied to the threshing chamber It is characterized in that it is configured to shift.

[0005]

According to this structure, the culms supplied to the handling room are subjected to the threshing action, and the untreated material that leaks out is sorted out. The untreated material that does not leak from the handling room as the unwound product is sent to the culm side. The processed material that is sent out from the dust port to the starting end side of the processing chamber, is beaten by the processing cylinder, and falls from the processing chamber is sorted out. In this case, the rotation speed of the processing drum automatically increases or decreases depending on whether the supply amount of the grain stalk supplied to the handling room is large or small. That is, when the supply amount of the cereal stalk is large, the rotation speed of the processing cylinder is increased to enhance the beating process, and the speed of the transition from the starting end to the end side of the processing chamber is increased by increasing the rotation speed. When the amount of grain culm supplied becomes small, the rotation speed of the processing cylinder is reduced and the transfer speed of the processed material in the processing chamber is slowed down, and the processing rate in the processing chamber is kept constant, and the grain processing is performed. Sufficient processing is performed, and the sufficiently processed material falls from the processing chamber and is sorted.
