PROBLEM TO BE SOLVED: To provide a thresher improved in material adaptability and screening throughput.SOLUTION: Tailings screened in a screening chamber 9 is discharged to a threshing chamber 19 or the screening chamber 19, alternatively. A screening chamber return port 60 for discharging tailings to an oscillating screening body 22 and a gathering board 49R for dispersing the processed material on the oscillating screening body 22 are disposed on one side of the screening chamber 9. A height of the gathering board 49R is controlled according to discharge destination of tailings. The gathering board 49R is disposed to at least partially overlap the screening chamber return port 60 and a machine body 3 in front-back direction.COPYRIGHT: (C)2014,JPO&INPIT【課題】材料適応性及び選別処理能力を向上した脱穀装置を提供する。【解決手段】選別室9で選別された二番物を扱室19と選別室9とに択一的に放出するように構成し、選別室9の一側方に、前記二番物を揺動選別体22に放出する選別室還元口60と、該揺動選別体22上の処理物を分散させる寄せ板49Rと、を配置し、該寄せ板49Rを、二番物の放出先に応じて高さ調節する。該寄せ板49Rを、選別室還元口60と機体3の前後方向に少なくとも一部が重なるように配置する。【選択図】図11
