PROBLEM TO BE SOLVED: To realize a compact combine capable of keeping harvest work efficiency even if grain culms to be harvested are animal feed rice in a large yield, long, or wet.SOLUTION: The combine comprises: a reaping device 3 on a front side of a vehicle body 1 including a travelling device 2 a threshing device 4 on an upper side of the vehicle body 1 and a threshing cylinder 7 disposed inside a threshing chamber 8 formed in an upper part of the threshing device 4. The threshing cylinder 7 includes a protrusion 114 and a recess 115 which are in an axial center direction of the threshing cylinder 12, formed alternately on an outer peripheral surface of a rotation body 61 supported by a threshing shaft 12. One side of the threshing chamber 8 rear part is communicated with a front part of a waste dust processing chamber 18 internally including a waste dust processing cylinder 17 so as to rotate via a communication port R.COPYRIGHT: (C)2016,JPO&INPIT【課題】収穫対象の穀稈が多収量の飼料用米であったり、長稈であったり、濡れた穀稈であっても、収穫作業の能率を維持できる、コンパクトなコンバインを具現する。【解決手段】走行装置(2)を備えた車体(1)の前側に刈取装置(3)を設け、車体(1)の上側には脱穀装置(4)を設け、脱穀装置(4)の上部に形成した扱室(8)に扱胴(7)を内装したコンバインにおいて、扱胴(7)は、扱胴軸(12)に支持された回転体(61)の外周面に、扱胴軸(12)の軸心方向に沿う凸部(114)と凹部(115)を交互に形成した構成とし、扱室(8)の後部一側には、排塵処理胴(17)を回転自在に内装した排塵処理室(18)の前部を、連通口(R)を介して連通させる。【選択図】 図8
