PROBLEM TO BE SOLVED: To solve a problem that a conventional threshing cylinder including a drum part formed by closing a portion between crosspiece members adjacent in a rotation direction by a shielding member does not have a constitution supporting an intermediate part in a length direction of the drum part and a burden in a threshing chamber increases.SOLUTION: In a threshing device, a threshing cylinder 21 including a take-in part 39 at a front part and a drum part 27 on a rear side is axially arranged in a threshing chamber 22, a threshing tooth support member 25 including plural threshing teeth 20 is arranged on the threshing cylinder 21 while spaced part from a threshing cylinder shaft 26 at a predetermined interval in a radial direction, the threshing tooth support member 25 is arranged across between a front plate 31 of the drum part 27 and a rear plate 32 on a rear side, a front/rear intermediate part of the threshing tooth support member 25 is attached on an intermediate partition plate 38 attached on the threshing cylinder shaft 26, and a bracket 36 holding the intermediate partition plate 38 from the front and rear is attached on the threshing tooth support member 25.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】回転方向に隣接した桟部材の間を遮蔽部材で塞いでドラム部を形成した、従来の扱胴では、ドラム部の長さ方向の中間部を支持する構成が無く、扱室内の負荷が大きくなると変形するという課題がある。【解決手段】前部の取込部39と、後側のドラム部27を備えた扱胴21を扱室22に軸装し、扱胴21は、扱歯20を複数設けた扱歯支持部材25を、扱胴軸26と径方向に所定間隔をおいて配置すると共に、扱歯支持部材25はドラム部27の前板31と後側の後板32とに渡しかけて構成し、扱歯支持部材25の前後中間部は前記扱胴軸26に取付けた中間仕切板38に取付け、扱歯支持部材25には、前記中間仕切板38を前後から挾持するブラケット36を取付けた脱穀装置。【選択図】図3
