<P>PROBLEM TO BE SOLVED: To provide a grain thresher in which power consumption is reduced and efficiency of threshing is improved. <P>SOLUTION: A cut-ears processing device 14 is arranged at a position for the processing material to be dropped in order to process the processing materials occurring when threshing grain straws 22 in a threshing cylinder 13. The threshing cylinder 13 has a plurality of threshing teeth 17 formed in flat shapes. The cut-ears processing device 14 has a cut-ears processing cylinder 40 rotated around an axis parallel to the axis of the threshing cylinder 13, and a receiving net 41 covering the lower side of the cut-ears processing cylinder 40. The cut-ears processing cylinder 40 is rotated in the same direction as the threshing cylinder 13. Thereby, since the processing materials in the cut-ears processing cylinder 40 are discharged toward the threshing cylinder 13 by the rotation of the cut-ears processing cylinder 40, it can be prevented that the processing materials are excessively accumulated between the cut-ears processing cylinder 40 and the receiving net 41. <P>COPYRIGHT: (C)2012,JPO&INPIT |
