PROBLEM TO BE SOLVED: To provide a threshing cylinder capable of suppressing weight increase of the threshing cylinder, and capable of being easily produced, with high rigidity.SOLUTION: A threshing processing part 40 is provided on a rear part of a raking part 30. In the threshing processing part 40, a front support member 41, an intermediate support member 43b, and a rear support member 42 are supported to a threshing cylinder spindle 19. A plurality of front division threshing tooth support members 45a are supported to the front support member 41 and the intermediate support member 43b in a state of being arranged at a same array pitch in a circumferential direction of the threshing processing part 40. A plurality of rear division threshing tooth support members 45b are supported to the intermediate support member 43b and the rear support member 42 in a state of being arranged at a same array pitch in the circumferential direction of the threshing processing part 40. A plurality of bar-shaped threshing teeth 44 are supported to respective front division threshing tooth support members 45a and the respective rear division threshing tooth support members 45b. Arrangements of the front division threshing tooth support members 45a and the rear division threshing tooth support members 45b are different from each other.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】扱胴の重量化を抑制しつつ、かつ、扱胴を容易に製作できるようにしつつ、剛性が高い扱胴を得る。【解決手段】掻込み部30の後側に扱き処理部40が設けられている。扱き処理部40において、扱胴支軸19に、前支持部材41、中間支持部材43b、後支持部材42が支持されている。前支持部材41と中間支持部材43bとに複数の前側分割扱歯支持部材45aが扱き処理部40の周方向に同じ配列ピッチで並ぶ状態で支持されている。中間支持部材43bと後支持部材42とに複数の後側分割扱歯支持部材45bが扱き処理部40の周方向に同じ配列ピッチで並ぶ状態で支持されている。各前側分割扱歯支持部材45a及び各後側分割扱歯支持部材45bに複数の棒状の扱歯44が支持されている。前側分割扱歯支持部材45aの配列と後側分割扱歯支持部材45bの配列とが異なっている。【選択図】図2
