PROBLEM TO BE SOLVED: To enlarge the volume of a grain-collecting tank, without causing the problem of conventional volume-enlarging means, in a structure of a grain-collecting part in a combine harvester which is constituted, with a machine frame for carrying and supporting a threshing device and the grain-collecting tank arranged in parallel in the right and the left direction, and sending out the grain by a bottom screw which is arranged along the bottom part of the grain-collecting tank in the front and the rear directions of the machine body, and unloading the grain sent out to the outside of the machine, by conveying the grains by means of a grain-unloading device which is installed to be connected to the grain-collecting tank.SOLUTION: The structure of the grain-collecting part in the combine harvester is constituted, by positioning the bottom screw 10 on the outside from the lateral outer end of the machine frame 2.0, to arrange the lower end of the grain-collecting tank 8 to be low.COPYRIGHT: (C)2009,JPO&INPIT【課題】 脱穀装置と穀粒回収タンクとを左右に並列して機体フレームに搭載支持し、前記穀粒回収タンクの底部に沿って機体前後向きに配備した底スクリューで穀粒をタンク外に送出し、送出された穀粒を穀粒回収タンクに連結装備した穀粒搬出装置で搬送して機外に排出するよう構成したコンバインの穀粒回収部構造において、従来の容量増大手段の問題を招くこと少なく、穀粒回収タンクの容量を増大できるようにする。【解決手段】 底スクリュー１０を機体フレーム２の横外端より外側に位置させることで、穀粒回収タンク８の下端を低く配置する。【選択図】 図１０
