Claims (1)

[Scope of Claim for Utility Model Registration] (a) A disc-shaped cutter disposed at the culm discharge port of a threshing device, the disc-shaped cutter comprising a high-speed rotating shaft equipped with a large number of disc blades;
A cutting device in which both ends of a low-speed rotating shaft equipped with a feeding body facing the disc blade are removably connected to a short shaft supported on a frame, (b) the inner end surface of the short shaft and the high-speed and low-speed rotating shafts are connected to each other. and (c) a key structure having an axis perpendicular to the axial direction of the rotating shaft, and (c) a key structure that is connected to the outside end of the short shaft only when the axis of the key structure is in a horizontal state. A culm cutting device characterized in that a transmission mechanism such as a pulley or a gear provided therein can be coupled to the frame body using a locking tool, so that rotation of the short shaft can be prevented.
