PROBLEM TO BE SOLVED: To aim at the improvement of mobility of a threshing device and a combine harvester loading the threshing device, and also aim at the improvement of working efficiency of threshing work and the reduction of production cost.SOLUTION: A threshing port (33) is formed at the outer sidewall (30) of a threshing chamber (22) to install a feed chain (34) for nip-conveying cereal culms along the threshing port (33), and a culm-discharging port (32) for discharging the discharged culms nip-conveyed by the feed chain (34) after threshing at the rear sidewall (25) of the threshing chamber (22) is formed by continuing to the threshing port (33) to arrange the final end part of nip conveyance of the feed chain (34) at a position in the vicinity of a rear sidewall (25) or at the position more biased in rear direction than that of the rear sidewall (25), and also a culm-discharging port (32) is opened toward the outside of the threshing device (3), thereby making a constitution that the discharged straw discharged from the culm-discharging port (32) after the threshing is released from the nip-holding of the feed chain (34) and directly discharged to the outside of the threshing device (3) from the culm-discharging port (32).COPYRIGHT: (C)2013,JPO&INPIT【課題】脱穀装置およびこの脱穀装置を搭載するコンバインの機動性を向上させると共に、脱穀作業能率の向上および製造原価の低減を図る。【解決手段】扱室(22)の外側壁(30)に扱口(33)を形成し、扱口(33)に沿って穀稈を挟持搬送するフィードチェン(34)を設け、扱室(22)の後側壁(25)にはフィードチェン(34)によって挟持搬送された脱穀後の排稈を排出する排稈口(32)を扱口(33)に連続して形成し、フィードチェン(34)の挟持搬送終端部を後側壁(25)の近傍の部位あるいは後側壁(25)よりも後方に偏倚した部位に配置すると共に、排稈口(32)を脱穀装置(3)の外部に向けて開口し、排稈口(32)から排出される脱穀後の排稈が、フィードチェン(34)による挟持を解除されて排稈口(32)から脱穀装置(3)の外部へ直接排出される構成とする。【選択図】 図2
