PROBLEM TO BE SOLVED: To prevent long straws, waste straws, and the like falling from the upper side from being wound around a transmission belt by a pulley cover (18) that covers a counter pulley (33) provided on a threshing counter shaft.SOLUTION: A combine harvester comprises: a threshing part (4) on a vehicle body (1) a feed chain (8) at an outside part of the threshing part (4) a threshing counter shaft (31) laterally laid across in the front side of the threshing part (4) a counter pulley (33) that transmits driving force via a belt, from the threshing counter shaft (31) to a hydraulic type continuously variable transmission (37) for driving a feed chain (8) and a selector such as a fanning mill (39) and a pully cover (18) for covering the front side, the upper side and the outside of the counter pulley (33). The pulley cover (18) is disposed between the feed chain (8) and the counter pulley (33) provided on the lower side of the feed chain (18).COPYRIGHT: (C)2014,JPO&INPIT【課題】脱穀カウンタ軸に備えたカウンタプーリ(33)をカバーするプーリカバー(18)によって、上方から落下してくる長藁や藁屑などが伝動ベルトへ巻き付ことを防止する。【解決手段】車体(1)上に脱穀部(4)を備え、脱穀部(4)の外側部にフィードチェン(8)を備え、脱穀部(4)の前側には脱穀カウンタ軸(31)を横架し、脱穀カウンタ軸(31)からフィードチェン(8)を駆動する油圧式無段変速装置(37)と唐箕(39)等の選別装置とにベルト伝動するカウンタプーリ(33)を備え、カウンタプーリ(33)の前側と上側と外側を覆うプーリカバー(18)を設ける。また、プーリカバー(18)を、フィードチェン(8)とフィードチェン(8)の下方に備えたカウンタプーリ(33)との間に配置する。【選択図】 図4
