PROBLEM TO BE SOLVED: To provide a combine that is capable of changing flow volume of the sorting air of a winnower with a simple structure.SOLUTION: A combine includes a threshing device that threshes crops reaped by a reaper at a machine body front. The threshing device includes: a threshing chamber for threshing the crops by a rotary threshing cylinder and a sorting unit positioned below the threshing chamber and sorting threshed crops using sorting air supplied by a winnower. An opening 216 for sucking the sorting air is formed in each of sidewalls 8A of left and right sides in the threshing device. The threshing device also includes: paired left and right opening adjustment mechanisms 217 capable of freely changing an opening degrees of the openings 216 of the left and right sides, respectively and an interlocking mechanism 222 for interlocking the paired opening adjustment mechanisms 217 to adjust the opening degrees.COPYRIGHT: (C)2015,JPO&INPIT【課題】簡単な構造により唐箕の選別風の風量を変更させることが可能なコンバインを提供する。【解決手段】機体前部の刈取部にて刈り取られた作物の脱穀処理を行う脱穀装置が、回転する扱胴により作物に対する扱き処理を行う扱室と、扱室の下方に位置して扱き処理物を唐箕により供給される選別風を用いて選別処理する選別部とを備えて構成され、脱穀装置における左右両側の側壁8Aの夫々に、選別風を吸い込むための開口216が形成され、左右両側の開口216の開度を変更調整自在な左右一対の開度調整機構217と、一対の開度調整機構217を連動させて開度を調整する連動機構222とが備えられている。【選択図】図31
