Threshing device having a screw type threshing drum of general-purpose combine

摘要

PROBLEM TO BE SOLVED: To provide a threshing apparatus preventing a speed difference in the transfer speed of grain culms between a take-in part of a threshing cylinder located near a take-in port from a feeder house and a threshing part at the rear thereof.;SOLUTION: The threshing apparatus is equipped with the screw threshing cylinder 6 of a general-purpose combine harvester. A series of impellers 30 are formed on the peripheral surface of the threshing cylinder 6 arranged in the front and rear directions in the threshing apparatus. Thereby, a great speed difference is prevented from being caused in a boundary between the take-in part 6a of the threshing cylinder 6 and a threshing part 6b. The grain culms are smoothly transferred to eliminate the stay of the grain culms and the rotation of the threshing cylinder 6 is smoothed to prevent useless high-load operation of an engine.;COPYRIGHT: (C)2004,JPO
