【産業上の利用分野】
本発明は例えば稲・麦・大豆など穀物を刈取って脱穀処理するようにした普通形コンバインに関する。
【0002】
【発明が解決しようとする課題】

【0003】
【課題を解決するための手段】
然るに、本発明は、脱穀部の前側にフィーダハウスを設け、該フィーダハウスの前側に穀物刈取ヘッダーを設けるコンバインにおいて、穀物刈取ヘッダーの穀稈掻込オーガと、フィーダハウスの供給コンベアとに、フィーダハウス後側の駆動軸を連結させると共に、前記穀稈掻込オーガ及び供給コンベアを逆転できる駆動モータ脱穀部前側にモータ台を介して設け、フィーダハウスの駆動軸にスプロケットを設けてチェンを介して駆動モータを連結させるもので、収穫作業中に刈取り穀稈が詰っても、前記駆動モータによって穀稈掻込オーガ及び供給コンベアを逆転させて詰った穀稈を排出し得、刈取り穀稈の詰りを速やかに解除して収穫作業を容易に再開させ得ると共に、フィーダハウス後部を連結させる脱穀部前側のスペースを利用して駆動モータを容易に設置し得、またフィーダハウスの駆動軸と脱穀部側の駆動モータとの組立て誤差をチェンの連結によって容易に吸収し得、フィーダハウスを含む刈取部の組付け取外し操作性の向上並びに昇降支持構造の簡略化などを容易に図り得るものである。
