PROBLEM TO BE SOLVED: To solve such a problem that the efficiency and accuracy of a treated product on an oscillating separation shelf is deteriorated because the treated product discharged from a threshing chamber is tangled on an oscillating shelf.SOLUTION: In the combine harvester, a threshing device 3 is provided on the upper side of a traveling device 2, a reaping device 5 is provided on the front side of the traveling device 2. The threshing device 3 includes: a fanning mill 22 below the threshing chamber 14 in which a treating barrel 20 is axially mounted and the oscillating separation shelf 24 for separating grains from foreign objects by blowing air from the fanning mill 22. A suction dust exhaust fan 34 for sucking the wind blown from the fanning mill 22 is provided at the upper side of the terminal end of the oscillating separation shelf 24. A spreading barrel 55 which performs driving rotation with the central focus on the shaft core of the cross direction is provided between the suction dust exhaust fan 34 and a vent 48 of the threshing chamber 14. A grain culm supplying/delivering device 12 changes the rotation speed according to the traveling speed for supplying and delivering grain culms to the spreading barrel 55 and the threshing chamber 14 of the threshing device 3.COPYRIGHT: (C)2012,JPO&INPIT【課題】脱穀室から排出される被処理物が揺動棚上で絡まって、揺動選別棚上の被処理物の効率および精度が低下する。【解決手段】走行装置2の上方に脱穀装置3を設け、走行装置2の前方に刈取装置5を設け、前記脱穀装置3は、扱胴20を軸装した脱穀室14の下方に唐箕22と該唐箕22からの送風により穀粒と異物とを選別する揺動選別棚24を設け、該揺動選別棚24の終端上方に前記唐箕22からの送風を吸引する吸引排塵ファン34を設け、該吸引排塵ファン34と前記脱穀室14の排出口48との間には左右方向の軸心を中心として駆動回転する拡散胴55を設け、該拡散胴55と前記脱穀装置3の脱穀室14に穀稈を供給搬送する穀稈供給搬送装置12とは走行速度に応じて回転速度を変更するようにしたコンバイン。【選択図】図2
