PROBLEM TO BE SOLVED: To enhance accuracy in sorting, efficiency in threshing work and the grain collecting rate by providing a function of collecting grains caught in discharged straws after threshing, and by adjusting the amount and direction of blowing air for sorting.SOLUTION: A partition plate (11K) is disposed closely to the outer periphery of a rear part of a threshing cylinder (10) within a threshing chamber (11), and separation teeth (10b) for separating the grains caught in discharged straws after threshing is disposed on the outer peripheral surface of the threshing cylinder (10) within a collection chamber (11F) formed on a rear side of the partition plate (11K). A support member (10c) for supporting and guiding the discharged straws after threshing into a working area of the separation teeth (10b) is disposed in a region along the outer periphery of the lower side of the threshing cylinder (10) within the collection chamber (11F). The direction of blowing air for sorting from a winnower (16) is adjustable.COPYRIGHT: (C)2012,JPO&INPIT【課題】脱穀後の排藁に入り込んだ穀粒を回収する機能を備えると共に、選別風の送風量と送風方向を調節自在とすることで、選別精度、脱穀作業能率、穀粒回収率を高める。【解決手段】脱穀室(11)内における扱胴(10)の後部外周に仕切板(11K)を近接して配置し、仕切板(11K)の後側に形成された回収室(11F)内における扱胴(10)の外周面上には、脱穀後の排藁に入り込んだ穀粒をこの排藁から分離する分離歯(10b)を設け、回収室(11F)内における扱胴(10)の下側外周に沿う部位に、脱穀後の排藁を支持して分離歯(10b)の作用域へ案内する支持部材(10c)を設ける。また、唐箕(16)からの選別風の送風方向を上下に調節自在とする。【選択図】 図5
