Claims

[Claims for Utility Model Registration] (1) In a threshing device for an ordinary combine harvester equipped with a built-in screw-type rotor, an impeller 2b having the same diameter or smaller diameter than the rotor spiral 2 wound around the outer circumference of the rotor 1 is used. A combine threshing device characterized in that a removable spiral 3 having a larger diameter than a rotor spiral 2 can be attached to the impeller 2b. (2) In a normal combine harvester with a built-in screw-type rotor, the tip of the rotor 1 has a large-diameter impeller 2a at the joint with the feeder chain 5, and the rotor spiral gradually changes from the large-diameter impeller 2a to a normal diameter. 2, and the rotor cover 7 that surrounds the screw type rotor is also shaped to have a diameter that gradually becomes thinner, and the diameter-reducing inclined cylinder portion 7 of the rotor cover 7 is
A threshing device for a combine harvester, characterized in that (a) ends at a position where the rotor spiral 2 is reached.
