PROBLEM TO BE SOLVED: To provide a combine capable of preferably selecting a processed product by selection wind even when an amount of the processed products supplied to a thresher is increased, and reducing loss of the processed products.SOLUTION: A thresher for processing harvested objects comprises a sieve case 40 which is driven to oscillate and a fan 30 for supplying selection wind. The sieve case 40 comprises: a crude separation part arranged on a rear side of an upper grain pan 42； and a precise selection part provided below the crude separation part, in which an introduction opening 47 through which the selection wind from the fan 30 passes is formed on a lower side of the front part of the sieve case 40. A partition member 48 for inhibiting the processed objects from moving in a direction of the introduction opening 47 and allowing passage of the selection wind, is provided between the introduction opening 47 and a front end of the crude selection part.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】脱穀装置に供給される処理物の量が増大しても選別風による選別を良好に行いつつ、処理物のロスを低減するコンバインを構成する。【解決手段】収穫物を処理する脱穀装置が、駆動揺動するシーブケース４０と、選別風を供給する唐箕３０とを備えている。シーブケース４０が、上部グレンパン４２の後方に配置された粗選別部と、この粗選別部の下方に設けられた精選別部と備え、唐箕３０からの選別風が通過する導入開口４７をシーブケース４０の前部の下方に形成している。導入開口４７と粗選別部の前端との間に、選別風の通過を許容し、処理物が導入開口４７の方向に移動するのを阻止する仕切部材４８を備えた。【選択図】図４
