PROBLEM TO BE SOLVED: To provide a threshing device including a cutting processing chamber which reduces a cutting load in cutting a waste culm, suppresses vibration and noise generated in cutting, and prevents deformation and generation of early wear of a blade and a receiving blade.SOLUTION: A rotation body 54 including plural blades 51 is arranged laterally in an upper part of a cutting processing chamber 50. Receiving blades 52 are arranged in a lower part of the cutting processing chamber 50. The blades 51 are arranged parallelly at predetermined intervals in a lateral direction of the rotation body 54 to form a blade group 58. The blade groups 58 are circumferentially arranged at predetermined intervals in a circumferential direction on an outer peripheral part of the rotation body 54. The blades 51 adjacent to each other in the lateral direction within the blade group 58 are arranged while being shifted from each other in the circumferential direction of the rotation body 54.SELECTED DRAWING: Figure 9 |
