PROBLEM TO BE SOLVED: To provide a threshing device which promotes separation of grains from grains with rachis branches and enhances selection accuracy.SOLUTION: In a threshing chamber 2, a threshing cylinder 9 rotated around a shaft in a front/rear direction is pivotally arranged. In a lower side of the threshing chamber 2, an oscillation selection shelf 26 oscillated in a front/rear direction is arranged. In an upper part of the oscillation selection shelf 26, a front side transfer shelf 32 receiving thresh-processed objects falling from a front side part of the threshing chamber 2, a rear side transfer shelf 33 receiving thresh-processed objects in a center part in a front/rear direction of the threshing cylinder 9, a sieve 34, and a straw rack 35 are arranged in this order from a front side to a rear side. In a lower part of the oscillation selection shelf 26, a selection net 36 is arranged, and in a lower side of the oscillation selection shelf 26, a fan 27, a first grain receiving gutter 51 with a first lateral transfer spiral 52, and a second grain receiving gutter 53 with a second lateral transfer spiral 54 are arranged in this order from a front side to a rear side in the threshing device.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】 穀粒と枝梗付穀粒との分離を促進し選別精度を高めた脱穀装置を提供する。【解決手段】 扱室(2)内に前後方向の軸回りに回転する扱胴(9)を軸架し、前記扱室(2)の下方には、前後方向に揺動する揺動選別棚(26)を配置し、該揺動選別棚(26)の上部には、扱室(2)の前側部から落下する脱穀処理物を受ける前側移送棚(32)と、扱胴(9)の前後方向中間部での脱穀処理物を受ける後側移送棚(33)と、シーブ(34)と、ストローラック(35)を前側から後側に向かってこの順に配置すると共に、揺動選別棚(26)の下部には選別網(36)を配置し、揺動選別棚(26)の下方には、唐箕(27)と、一番横移送螺旋(52)付の一番穀粒受け樋(51)と、二番横移送螺旋(54)付の二番穀粒受け樋(53)を前側から後側に向ってこの順で配置した脱穀装置とする。【選択図】図2
