Description

【０００１】
【発明の属する技術分野】
この発明は、刈取り穀稈を移送する移送終端部の刈取機の穀稈供給移送装置と、穀稈を脱穀する脱穀機のフィードチェンとの間には、補助移送チェン装置を設け、該補助移送チェン装置の下側には、移送中の穀稈から落下する藁屑等を受けて排出する受戸樋装置を設けた技術であり、コンバインの藁屑等除去装置として利用できる。
【０００２】
【従来の技術】
コンバインで立毛穀稈の収穫作業は、このコンバインを穀稈の植付圃場を走行させて、走行車台の前方部に設けた刈取機で穀稈は刈取りされ、この刈取り穀稈は、この刈取機で後方上部へ移送され、走行車台の上側へ載置した脱穀機の前側の前側フィードチェンから後側フィードチェンへ引継ぎされて、この後側フィードチェンと、挟持杆とで脱穀機内を挟持移送中に脱穀され、脱穀済み穀粒は、横側へ設けた穀粒貯留タンク内へこの脱穀機から供給されて、一時貯留される。
【０００３】
特に、特開平１１−９０６６号の如く穀稈の刈取り収穫作業中は、刈取機の刈刃で刈取りされて、前処理搬送装置で移送される刈取り穀稈は、扱深さ搬送体で引継ぎ移送され、脱穀機の前側へ設けた前側フィードチェンで引継ぎ移送され、脱穀機に設けた後側フィードチェンと、挟持杆とヘ引継ぎされて、脱穀機内を挟持移送中に脱穀されるが、前側フィードチェンで引継ぎ移送中の穀稈からは、藁屑等が落下して、この藁屑等は、走行用のミッションケース、走行車台、及び其の他部品等の上側へ堆積することがある。
