PROBLEM TO BE SOLVED: To constitute a threshing device in which the sorting performance is never lowered even if the processed material increases.SOLUTION: A sorting unit 32 includes: a chaff sieve 67 for coarsely sorting the processed material from a threshing processing unit 43 to a sieve case 65 swinging in the longitudinal direction of a machine body; a grain sieve 71 arranged in a position overlapped with the chaff sieve 67 in a plan view, and sorting the grain out of the processed material to make the grain come down; and a sorting member 72 capable of sorting the processed material at the upstream side position in the conveyance direction of the processed material of the grain sieve 71 between the chaff sieve 67 and the grain sieve 71.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】処理物が増大しても、選別性能が低下することのない脱穀装置を構成する。【解決手段】選別部32が、機体の前後方向に揺動するシーブケース65に対し、扱処理部43からの処理物を粗選別するチャフシーブ67と、平面視においてチャフシーブ67と重複する位置に配置され、処理物から穀粒を選別して漏下させるグレンシーブ71と、チャフシーブ67とグレンシーブ71との間で、グレンシーブ71のうち処理物の搬送方向の上流側位置に処理物の選別が可能な選別部材72とを備えた。【選択図】図3
