<P>PROBLEM TO BE SOLVED: To reduce external discharge losses by collecting grains sticking into grain culms in a treatment chamber. <P>SOLUTION: The threshing device includes: a feed chain on one side in the lateral direction of the treatment chamber 11 to which a threshing cylinder 12 is rotatably mounted; a No.4 treatment chamber 14 in which a No.4 threshing cylinder 15 is rotatably mounted on the rear side of the treatment chamber 11; and comb-teeth-shaped No.4 treatment teeth 16 on the outer peripheral surface of the No.4 threshing cylinder 15. The No.4 treatment teeth 16 are composed of a plurality of comb teeth 16a arranged along an axial direction of the No.4 threshing cylinder 15 on the outer peripheral surface of the No.4 threshing cylinder 15, and a scraping plate 16b which connects a base of the comb teeth 16a to the outer peripheral surface of the No.4 threshing cylinder 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
