【発明の属する技術分野】
この発明は、コンバインの穀粒排出装置に関するものである。
【０００２】
【従来の技術】
例えば、コンバインで立毛穀稈の刈取り収穫作業は、このコンバインの前部に設けた刈取機で立毛穀稈は刈取りされ、刈取り穀稈は、この刈取機で後方上部へ移送されて脱穀機へ供給され、この脱穀機内を挟持移送中に脱穀され、脱穀済みで選別済みの穀粒は、この脱穀機の右横側に設けた穀粒貯留タンク内へ供給されて一時貯留される。
【０００３】
前記穀粒貯留タンク内へ貯留した穀粒を機外へ排出するときには、この穀粒貯留タンク内の穀粒は、後側に設けた縦移送筒内へ移送供給され、この縦移送筒から伸縮穀粒排出装置内へ移送供給されるが、この前段で伸縮装置等により、伸縮穀粒排出装置を所定の排出位置へ伸張、左右旋回、及び昇降制御して、所定の排出位置へセットする。
【０００４】
所定の排出位置へセットした伸縮穀粒排出装置の固定用移送筒内へ縦移送筒から穀粒は供給され、この固定用移送筒へ内装した固定移送螺旋で引継ぎ移送され、固定用移送筒の外周部へ収縮自在に挿入した移動用移送筒内へ供給される。この移動用移送筒へ伸縮自在で、固定用移送筒の移送終端部に設けた後支持メタルと、移動用移送筒の前端部に設けた排出筒の前側板に設けた前支持メタルとによって、軸支した移動螺旋軸の移送始端部側へ固定して軸支した後移動移送螺旋と、この後移動移送螺旋へ係合すると共に、複数個が伸縮自在に係合した中移動移送螺旋と、この中移動移送螺旋と係合して、移動螺旋軸の移送終端部側へ軸支して、固定した前移動移送螺旋とにより、順次固定用移送筒の固定移送螺旋から、移動用移送筒内へ供給され、この移動用移送筒内を、後・各中・前移動移送螺旋へと順次引継ぎ移送されて、排出筒内へ移送され、この排出筒の排穀口から機外へ穀粒は排出される。
【０００５】
【発明が解決しようとする課題】
移動用移送筒へ内装した前・後・各中移動移送螺旋を軸支する伸縮移動自在な移動螺旋軸は、固定用移送筒の移送終端部に設けた後支持メタルと、移動用移送筒の先端部に設けた排出筒の前側板に設けた前支持メタルとの２箇所で軸支した２点支持方式によって、支持されていることにより、支持スパンが長く、このために、移動螺旋軸が大きく振れることがあり、この振れが原因で異常音が発生したり、又、移送中の穀粒がたたかれて、脱ぷ粒、及び損傷粒が発生することがあったが、この発明により、これらの問題点を解決しようとするものである。
【０００６】
【課題を解決するための手段】
このために、この発明は、穀粒を受けて移送して排出する固定移送螺旋（７）を内装した固定用移送筒（８）と、該固定用移送筒（８）の外周部へ挿入して伸縮装置（１４）によって伸縮自在に構成した移動用移送筒（１３）と、該移動用移送筒（１３）の前端部の排出筒（３５）とを設け、前記移動用移送筒（１３）と排出筒（３５）とに伸縮自在な移動螺旋軸（９）を内装し、該移動螺旋軸（９）に前・後移動移送螺旋（１１，１０）を軸支すると共に該前・後移動移送螺旋（１１，１０）間に中移動移送螺旋（１２）を伸縮自在に軸支し、前記移動螺旋軸（９）の移送始端部側と中間部と移送終端部とを、固定用移送筒（８）の移送終端に設けた後支持メタル（３０）と排出筒（３５）を形成する後側板（３５ｂ）の近傍に設けた中支持メタル（３５ｄ）と排出筒（３５）を形成する前側板（３５ｃ）に設けた前支持メタル（３５ｅ）との３個所で支持して設けるにあたり、前記中支持メタル（３５ｄ）を排出筒（３５）へ装着するために設ける中支持メタル（３５ｄ）の左右両側の左・右支持アーム（３５ｆ，３５ｈ）の取付孔中心位置（ル，ル）を、該中支持メタル（３５ｄ）の移動螺旋軸（９）を軸支する孔中心位置（ト）よりも上下方向のいずれか一方側へ所定寸法（Ｎ）偏位させて設けたことを特徴とするコンバインの穀粒排出装置としたものである。
【０００７】
コンバインで立毛穀稈の刈取り収穫作業は、このコンバインの前部に設けた刈取機で立毛穀稈は刈取りされ、刈取り穀稈は、この刈取機で後方上部へ移送されて脱穀機へ供給され、この脱穀機内を挟持移送中に脱穀され、脱穀済みで選別済みの穀粒は、この脱穀機の右横側に設けた穀粒貯留タンク内へ供給されて一時貯留される。
【０００８】
前記穀粒貯留タンク内へ貯留した穀粒を機外へ排出するときには、この穀粒貯留タンク内の穀粒は、後側に設けた縦移送筒内へ移送供給され、この縦移送筒から伸縮穀粒排出装置内へ移送供給されるが、この前段で伸縮装置等により、伸縮穀粒排出装置を所定の排出位置へ伸張、左右旋回、及び昇降制御して、所定の排出位置へ移動させてセットする。
【０００９】
所定の排出位置へセットした伸縮穀粒排出装置の固定用移送筒８へ縦移送筒から穀粒は供給され、この固定用移送筒８へ内装した固定移送螺旋７で引継ぎ移送され、固定用移送筒８の外周部へ収縮自在に挿入した移動用移送筒１３内へ供給される。この移動用移送筒１３内へ供給された穀粒は、この移動用移送筒１３内を、後・各中・前移動移送螺旋１０，１２，１１へと順次引継ぎ移送されて、排出筒３５内へ移送され、この排出筒３５の排穀口から機外へ穀粒は排出される。

【発明の効果】
この発明によると、移動螺旋軸９の移送始端部側と中間部と移送終端部側とを後支持メタル３０と中支持メタル３５ｄと前支持メタル３５ｅとで軸支して、３箇所で軸支した３点支持方式としたことにより、支持スパンが短くなり、このために、移動螺旋軸９が大きく振れることがなくなり、異常音の発生を防止できる。又、振れが少なくなったことにより、移送中の穀粒がたたかれることがなくなり、脱ぷ粒、及び損傷粒の発生を防止できる。
また、中支持メタル３５ｄを排出筒３５へ装着するために設けるこの中支持メタル３５ｄの左右両側の左・右支持アーム３５ｆ，３５ｈの取付孔中心位置（ル）を、中支持メタル３５ｄの移動螺旋軸９を軸支する孔中心位置（ト）よりも上下方向いずれか一方側の穀粒排出の抵抗にならない側へ所定寸法（Ｎ）偏位させて設けることにより、中支持メタル３５ｄの左・右支持アーム３５ｆ，３５ｈ部が、穀粒排出の抵抗になることが少なくなり、スムーズに穀粒排出を行うことができる。
