Description

【０００１】
【発明の属する技術分野】
本発明は、稲・麦・大豆などの穀物を収穫するものでスクリュー形扱胴や、二番還元物の枝梗処理装置を具備したコンバインに関する。
【０００２】
【従来の技術】
円筒形胴部の最前部を除く外周面の大部分範囲個所に被処理物移送用の螺旋部材を固設され前記最前部に被処理物取込用のインペラを固設された前後向きのスクリュー形扱胴を備え、該スクリュー形扱胴の横側近傍に二番還元物用の枝梗処理装置を配設されているコンバインは存在している（特許文献１参照）。
【０００３】
上記枝梗処理装置は、前後向き軸回りへ回転される処理胴を有すると共に該装置で処理された後の被処理物を放出するための被処理物放出口が前記インペラから後方へ離れて位置されると共に前記スクリュー形扱胴の下方に設けられた揺動選別盤のフィードパンの直上へ向かう下向きとなされている。

【発明が解決しようとする課題】
上記した従来のコンバインでは、前記枝梗処理装置の被処理物放出口から放出された二番物が被処理物放出口の真下のフィードパン上の局部個所に集中して落下するため、二番物はフィードパン上で均等に拡散され難いのであり、このことが揺動選別盤の選別性能を低下させる要因をなしている。また前後向き軸回りへ回転される処理胴は扱室内で大きなスペースを必要とするため機体のコンパクト化を妨げるものである。
本発明は斯かる問題点を簡易に解消することのできるコンバインを提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するため、本発明は次のようなものとなす。
即ち、請求項１記載の発明は、円筒形胴部の外周面の大部分範囲個所に被処理物移送用の螺旋部材を固設された前後向きのスクリュー形扱胴を備え、該スクリュー形扱胴の横側近傍に二番還元物用の枝梗処理装置を配設したコンバインにおいて、前記枝梗処理装置を前記スクリュー形扱胴の最前部に取り付けられた被処理物取込用のインペラの後端個所と略同一の前後方向位置に配設したものである。
この発明によれば、前記インペラが前記スクリュー形扱胴と同体状に回転されて前記スクリュー形扱胴の回転方向且つ機体後方へ向かう比較的強い風を発生させるものとなり、該風が前記枝梗処理装置から放出される被処理物をフィードパン上で比較的広範囲に拡散させるものとなる。
【０００７】
また請求項２記載の発明は、円筒形胴部の外周面の大部分範囲個所に被処理物移送用の螺旋部材を固設された前後向きのスクリュー形扱胴を備え、該スクリュー形扱胴の横側近傍に二番還元物用の枝梗処理装置を配設したコンバインにおいて、前記枝梗処理装置を前記スクリュー形扱胴の最前部に取り付けられた被処理物取込用のインペラの後端個所と略同一の前後方向位置に配設するほか、前記枝梗処理装置の被処理物放出口を前記スクリュー形扱胴側へ向かう略水平横方へ向けて開口させたものである。
この発明によれば、請求項１記載の発明による作用のほかに次のような作用が得られるのであって、即ち、前記被処理物放出口が前記枝梗処理装置の処理した被処理物を前記スクリュー形扱胴側へ向かう略水平横方へ向けて放出するため、被処理物の放出方向と前記インペラで発生された風の流れ方向とを関連させることにより被処理物はフィードパン上にて一層、広範囲且つ効果的に拡散されるものとなる。
【０００８】
また請求項３記載の発明は、円筒形胴部の外周面の大部分範囲個所に被処理物移送用の螺旋部材を固設された前後向きのスクリュー形扱胴を備え、該スクリュー形扱胴の横側近傍に二番還元物用の枝梗処理装置を配設したコンバインにおいて、前記枝梗処理装置の処理胴が左右向き軸回りへ回転される構成としたものである。
この発明によれば、前記枝梗処理装置の処理胴が左右向き軸回りへ回転されるため、前記スクリュー形扱胴の近傍で前記枝梗処理装置の占める空間は前記処理胴が前後向き軸回りへ回転されるものに較べて小さくなり、その分、前記枝梗処理装置は前記インペラの発生した風の流れに対する障害となり難くなって被処理物はフィードパン上にて一層、広範囲且つ効果的に拡散されるものとなるほか、前記枝梗処理装置の存在する個所の機体（特に脱穀部）の左右幅をコンパクト化させる上でも寄与するのであり、また前記枝梗処理装置内の被処理物を前記スクリュー形扱胴側へ向かう略水平横方へ向けて放出させる構造が容易に実現されるものである。
【０００９】
また請求項４記載の発明は、円筒形胴部の外周面の大部分範囲個所に被処理物移送用の螺旋部材を固設された前後向きのスクリュー形扱胴を扱室内に架設すると共に、該スクリュー形扱胴の横側近傍に二番還元物用の枝梗処理装置を配設したコンバインにおいて、前記枝梗処理装置を前記スクリュー形扱胴の最前部に取り付けられた被処理物取込用のインペラの後端個所と略同一の前後方向位置に配設すると共に、前記枝梗処理装置の処理ケースのうち処理胴周面を囲む範囲の処理終端側部分を前記扱室内に位置させ且つ前記処理胴の略上半分範囲を覆っていない形態となしたものである。
この発明によれば、請求項１記載の発明による作用のほかに次のような作用が得られるのであって、即ち、前記枝梗処理装置の処理ケースのうち処理胴周面を囲む範囲の処理終端側部分を前記扱室内に位置させ且つ前記処理胴の略上半分範囲を覆っていない形態となしてあるため、前記扱室内で脱穀された穀粒が前記処理終端側部分の処理ケース内に落ち込んでも前記処理胴が前記処理終端側部分の処理ケース内から放出するものとなり、従って前記扱室内で脱穀された穀粒が前記処理ケース上に滞積することの生じないものとなる。
【００１０】
また請求項５記載の発明は、円筒形胴部の外周面の大部分範囲個所に被処理物移送用の螺旋部材を固設された前後向きのスクリュー形扱胴を備え、該スクリュー形扱胴の横側近傍に二番還元物用の枝梗処理装置を配設したコンバインにおいて、前記枝梗処理装置を前記スクリュー形扱胴の左右側のうち該スクリュー形扱胴の回転方向上手側に設けると共に前記枝梗処理装置の処理胴が左右向き軸回りへ回転される構成となしたものである。
この発明によれば、請求項３記載の発明による効果のほかに次のような効果が得られるのであって、即ち、前記枝梗処理装置を前記スクリュー形扱胴の左右側のうち該スクリュー形扱胴の回転方向上手側に設けることにより、前記スクリュー形扱胴が回転して発生させる該扱胴の回転方向へ向かう風が、前記枝梗処理装置から放出される被処理物をフィードパン上にて一層、広範囲且つ効果的に拡散させるものとなる。
【００１１】
また請求項６記載の発明は、円筒形胴部の外周面の大部分範囲個所に被処理物移送用の螺旋部材を固設された前後向きのスクリュー形扱胴を備え、該スクリュー形扱胴の横側近傍に二番還元物用の枝梗処理装置を配設したコンバインにおいて、前記枝梗処理装置の被処理物放出口を前記揺動選別盤のフィードパンの始端寄り位置の真上に位置させたものである。
この発明によれば、前記被処理物放出口が前記枝梗処理装置の処理した被処理物を前記フィードパンの始端寄り位置に落下されるため、被処理物は前記フィードパン上でこれの後端に到達するまでの比較的長い前後方向範囲で処理されるようになり、その層厚の均平化を促進されるものとなる。
【００１２】
また請求項７記載の発明は、円筒形胴部の外周面の大部分範囲個所に被処理物移送用の螺旋部材を固設された前後向きのスクリュー形扱胴を備えると共に、前記スクリュー形扱胴の直下に、フィードパンの後側にチャフシーブを連設された揺動選別盤を、そして前記スクリュー形扱胴の横側近傍に、二番還元物用の枝梗処理装置を配設されているコンバインにおいて、前記枝梗処理装置の被処理物放出口を前記揺動選別盤のフィードパンの始端寄り位置の真上に位置させ、且つ、前記フィードパンの後端と前記チャフシーブの前端と間に形成した風通路を通じて選別風が該風通路の下側から上側へ向けて流れる構成としたものである。
この発明によれば、請求項６記載の発明による作用のほかに次のような作用が得られるのであって、即ち、前記フィードパンの後端と前記チャフシーブの前端と間に形成した風通路を通じて該風通路の下側から上側へ向けて選別風が流れる構成としたため、被処理物放出口から放出された被処理物がその選別風によっても飛散されてフィードパンなどの上方にてさらに効果的に拡散されるものとなる。
【００１３】
また請求項８記載の発明は、請求項１〜７の何れかに記載のコンバインにおいて、前記枝梗処理装置の枝梗処理胴を処理作用程度の異なる別のものと交換装着可能となしたものである。
この発明によれば、稲のような枝梗の付着し易い穀物は処理程度の強い枝梗処理胴で強力に処理され、また麦のような枝梗の付着し難い穀物は処理程度の弱い枝梗処理胴で軽く処理されるものとなる。
【００１４】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて詳述する。図１はコンバイン全体の側面図、図２は同平面図であり、図中（１）は走行クローラ（２）をトラックフレーム（３）に装備する機台、（４）は軸流式のスクリュー形扱胴（５）及び選別機構（６）などを備えていて前記機台（１）に搭載する脱穀部、（７）は揚穀筒（８）を介して取出す脱穀部（４）の穀粒を溜める穀物タンク、（９）は前記脱穀部（４）の下部前方に油圧シリンダ（１０）を介して昇降可能に装設する刈取部、（１１）は運転席（１２）及び運転操作部（１３）を備えて前記穀物タンク（７）の前方に配設させる運転キャビン、（１４）は前記穀物タンク（７）の後方に備えていてエンジン（１５）を内設するエンジン部、（１６）は前記穀物タンク（７）内の穀粒を取出す上部穀粒搬出オーガである。
【００１５】
そして、前記刈取部（９）は、未刈り穀稈を取入れる穀物刈取ヘッダー（１７）と、該ヘッダー（１７）の後部略中央に連結させて刈取穀稈を脱穀部（４）に送給するフィーダハウス（１８）によって構成すると共に、未刈り穀稈掻込み用リール（１９）と、往駆動型刈刃（２０）と、穀稈掻込オーガ（２１）とを前記穀物ヘッダー（１７）に備え、前記ヘッダー（１７）に取込まれる刈取穀稈をフィーダハウス（１８）に内設する供給チェンコンベア（２２）を介し脱穀部（４）に送り込んで脱穀処理するように構成している。
【００１６】
また、前記脱穀部（４）の右外側には二番還元コンベア（２３）を配備させると共に、これの搬送終端に連続して枝梗処理装置１０１を設け、二番処理物を二番還元コンベア（２３）及び枝梗処理装置（１０１）を通じて選別機構（６）に還元し再選別するように構成している。
【００１７】
図３に示す如く、前記スクリュー形扱胴（５）は、脱穀部（４）前後長と略等しい長さの円筒形胴部（２４）を具備し、この胴部（２４）の最前部をなす円錐状外周面に螺旋面形の一対のインペラ（１００）（１００）を二条巻き状に固定して形成された取込部（２４ａ）と、この胴部（２４）外周に巻装して放射状に立設させる螺旋部材（２５）を固定して形成された直円筒状扱ぎ処理部（２４ｂ）と、この胴部（２４）の後端外周に排塵突起（２６）を固定して形成された排塵部（２４ｃ）とを形成されたもので、前記スクリュー形扱胴（５）を機体前後方向に軸支し、前記フィーダハウス（１８）に連通する扱室（２７）前側の投入口（２８）に扱胴（５）前端部を臨ませて設けると共に、扱室（２７）後側の排塵口（２９）に扱胴（５）の後端部を臨ませるものであり、前記排塵口（２９）を除く前記扱胴（５）下側に受網（３０）を張設し、フィーダハウス（１８）から刈取り穀稈を全量投入して脱穀するように構成している。
【００１８】
この際、インペラ（１００）（１００）の高さは螺旋部材（２５）のそれよりも大きくなして、インペラ（１００）外周縁の回転半径と、螺旋部材（２５）の外周縁の回転半径とを略々合致させるか若しくは前者を後者よりも大きくなすのであり、またインペラ（１００）のリード角度は螺旋部材（２５）のそれよりも格段に大きくなしてある。従って刈取り穀稈は取込部（２４ａ）によりフィーダハウス（１８）からの刈取り穀稈を効果的に取り込むことができるのである。そして、このときスクリュー形扱胴（５）は例えば凡そ７１５ｒｐｍ程度で回転されるため、インペラ（１００）はその形状に起因してスクリュー形扱胴（５）の回転方向（ｆ１）且つ機体後方へ向かう比較的強い風を発生させるのである。
【００１９】
また図４にも示す如く、前記選別機構（６）は前後の揺動選別盤（３１）（３２）を備えたものとなし、揺動リンク（３３）（３４）及びアーム（３５）を介して前後方向に前後選別盤（３１）（３２）を揺動駆動すると共に、前記扱胴（５）前部下方に位置させるフィードパン（３６）と、穀物漏下量を調節自在な第１チャフシーブ（３７）と、そのチャフシーブ（３７）下方に設けるグレンシーブ（３８）とを前選別盤（３１）に設ける一方、前記チャフシーブ（３７）後側に連設する第２チャフシーブ（３９）と、一番及び二番流穀板（４０）（４１）とを後揺動選別盤（３２）に設けている。
【００２０】
第１チャフシーブ（３７）及びグレンシーブ（３８）の下方に第１及び第２風路（４２）（４３）を介して選別風を供給する唐箕ファン（４４）と、グレンシーブ（３８）からの穀粒を受取って揚穀筒（８）に送出する一番樋（４５）及び一番コンベア（４６）と、二番流穀板（４１）からの還元物を二番還元コンベア（２３）に送出する二番樋（４７）及び二番コンベア（４８）と、前記チャフシーブ（３９）後端を臨ませる三番口（４９）とを形成し、一番樋（４５）の穀粒をタンク（７）に、また二番樋（４７）の還元物をフィードパン（３６）に送出するように構成している。
【００２１】
後選別盤（３２）前側に一番流穀板（４０）を固定させ、前後選別盤（３１）（３２）の重量差を小さくし、またグレンシーブ（３８）の後端よりも後方かつ下方に一番流穀板（４０）を配設すると共に、本機脱穀部（４）の左右側壁（５０）の外側に支点軸（５１）を介して回動自在に軸支させる揺動アーム（３５）両端に前後選別盤（３１）（３２）の前後端を連結させ、一方が前方移動のときにもう一方が後方移動する逆位相駆動によって前後選別盤（３１）（３２）を揺動させ、前後選別盤（３１）（３２）が最接近または最離反したときでも、またグレンシーブ（３８）の穀粒量が多いときでも、グレンシーブ（３８）からの穀粒を一番流穀板（４０）から一番樋（４５）に必ず落下させ、またグレンシーブ（３８）に対して一番流穀板（４０）を逆位相揺動することにより、一番流穀板（４０）での穀粒の滞留を防いで湿材での連続作業を可能にさせ、前記板（４０）上で穀粒と塵をほぐす作用を行わせて選別性能を向上させるように構成している。
【００２２】
次に、枝梗処理装置（１０１）及びこれに関連した機構について、図５及至図１１をも参照して説明する。
枝梗処理装置（１０１）は穀物タンク（７）の裏側、つまり、穀物タンク（７）の左側で脱穀部（４）の右側に位置され、二番還元コンベア（２３）の搬送終端個所の下側近傍に配置されている。この際、穀物タンク（７）は機台（１）上において右外側への移動可能に固定されている。従って穀物タンク（７）を外方へ移動することによって枝梗処理装置（１０１）を容易にメンテナンスすることができ、後述する制御弁（６０）の調整等もできる。
【００２３】
さらに詳細に説明すると、枝梗処理装置（１０１）は、図５に示すように側面視においてスクリュー形扱胴（５）の取込部（２４ａ）のインペラ（１００）の後端個所（ｐ１）近傍で且つ、フィードパンの始端寄り位置の真上で且つ、図６に示すように正面視において前記スクリュー形扱胴（５）の左右側のうち該スクリュー形扱胴（５）の回転方向（ｆ１）上手側で且つ、前記スクリュー形扱胴（５）の外周縁の下部近傍高さに位置されている。
【００２４】
図７及び図８に示すように、枝梗処理装置（１０１）の枝梗処理胴（５２）は左右向き軸（５３）回りへ回転駆動されるものとなされていて、外周面には図１０中に示すように左端側から複数の取込羽根（５４）、複数の処理歯（５５）、そして複数の跳ね出し羽根（５６）がこの順に設けられ、これらは互いに適宜間隔を開けて配置されている。該枝梗処理胴（５２）は左右向きの略円筒状の筒体からなる処理ケース（５７）内に収納されており、該処理ケース（５７）の右側上後部に設けられた投入口（５８）を介して二番還元コンベア（２３）の搬送終端部と連通されており、扱室（２７）の外方個所となる部分を分解開放することにより枝梗処理胴（５２）を図６Ａに示す他の形式のものと交換装着できるようになされている。該処理ケース（５７）の内側面には、ツースバー（固定側処理刃）（５９）や、後述する制御弁（６０）が突設されている。
なお、図６Ａに示す枝梗処理胴（５２）は外周面に螺旋部材（６１）を固設したもので、この実施例において処理ケース（５７）に収容されている図１０に示す枝梗処理胴（５２）に較べて枝梗除去能力が劣るものであり、これを処理ケース（５７）内に装着するときはツースバー（５９）は取り外される。
【００２５】
該処理ケース（５２）は、図７及び図９に示すように、枝梗処理胴（５２）の周面を囲む範囲の処理終端側部分（５７ａ）を扱室（２７）内に位置させ且つ枝梗処理胴（５２）の略上半分範囲を覆っていない形態となされている。従って受網（３０）から漏下した籾などが上方から処理ケース（５７）の処理終端側部分（５７ａ）の内方に落下することが生じるのであり、このように落下した籾などは枝梗処理胴（５２）の被処理物移送作用により処理ケース（５７）内方でスクリュー形扱胴（５）側などへ向けて略水平方向へ送り移動される。ここで、扱室（２７）内に位置した処理ケース（５７）部分である処理終端側部分（５７ａ）が枝梗処理胴（５２）の全周囲を包囲していると、受網（３０）から漏下した籾などが処理ケース（５７）部分の上面に滞積することが生じ得るが、上記のように処理ケース（５７）は扱室（２７）内において枝梗処理胴（５２）の略上半分範囲を覆っていないため籾やわらくずなどの滞積は生じない。
【００２６】
また、処理ケース（５７）の左端面の略全面を被処理物放出口（６２）となしてあって、該放出口（６２）を脱穀部（４）の前端部の受網（３０）の下側近傍でしかも揺動選別盤（３１）のフィードパン（３６）上方に臨ませて配置している。そして被処理物放出口（６２）近傍の処理ケース（５７）の処理終端側部分（５７ａ）の最低位置から図７に示す適当距離（Ｌ１）だけ後側へ変位させた位置から斜め上方へ向かう支持棒部材（６３）を設け、該支持棒部材（６３）の上部に、枝梗処理胴（５２）の回転中心をなす左右向き軸（５３）の先端を回動自在に支持させている。この際、支持棒部材（６３）は適当距離（Ｌ１）だけ偏倚しているため処理ケース（５７）内の最低部上での被処理物放出口（６２）へ向かう籾などの移動を妨げるものとならなず、籾などは処理ケース（５７）内に残留しなくなるのである。
【００２７】
以上の構成において、二番還元コンベア（２３）からの二番物の流れを説明すると、二番物は、投入口（５８）より枝梗処理装置（１０１）内へ投入された後、枝梗処理胴（５２）の回転により、取込羽根（５４）に補助されて機体左方向へ移動され、続いて該枝梗処理胴（５２）の外周に備える処理歯（５５）と、枝梗還元装置（１０１）の外枠を構成する処理ケース（５７）の内側面に突設したツースバー（５９）とにより、枝梗を除去されつつ被処理物放出口（６２）近傍まで搬送され、続いて跳ね出し羽根（５６）に補助されて、該放出口（６２）からスクリュー形扱胴（５）側へ向けて跳ね出され、脱穀部（４）の前端部、即ち、フィードパン（３６）の前部表面上へ落下する。
【００２８】
また前記枝梗処理胴（５２）は、図５及び図６に示す如く機体進行方向と直交した左右方向へ向けて配置されており、該枝梗処理胴（５２）の回転方向（ｆ２）は機体進行方向左側面視において時計回りとなされ、該枝梗処理胴（５２）の回転速度は凡そ５００ｒｐｍ程度となされている。
前記投入口（５８）より投入される二番物は、枝梗処理胴（５２）の回転により、処理ケース（５７）の内方端から被処理物放出口（６２）へ向けて移動されるのであり、該移動により該放出口（６２）から放出される際は、スクリュー形扱胴（５）の回転による風の流れ方向へ、即ちスクリュー形扱胴（５）側の水平方向へ向かいつつ機体後方へ向かうように流され、フィードパン（３６）上の広範囲に及ぶように飛散される。
【００２９】
一方では図１２に示すように、フィードパン（３６）の後端（ｐ２）と第１チャフシーブ（３７）の前端（ｐ３）との間に風通路（ｔ）が形成されているため、第一風路（４２）から送り出された選別風がその風通路（４２）を通じてこの風通路（４２）の下側から上側へ向けて流れるのであり、このように流れる選別風が枝梗処理装置（１０１）の被処理物放出口（６２）から放出された穀粒などをさらに均等に飛散させるものとなる。
【００３０】
こうして、フィードパン（３６）などの上面での二番物の均等拡散が確保されて、フィードパン（３６）などでの局所的な二番物の滞積が阻止され、フィードパン（３６）上の籾層は全体的に均等な厚さとなって薄くなり、フィードパン（３６）や第１チャフシーブ（３７）での処理が効率的に行われ、一番コンベア（４６）への穀粒の漏下が的確に行われるようになって、選別性能の向上が図られるのである。
【００３１】
次に、枝梗処理装置（１０１）への動力伝達構成について図２、図３、図８及び図９を参照して説明する。
枝梗処理装置（１０１）への動力の伝達において、駆動源であるエンジン（１５）からの駆動は一番コンベア（４６）、二番コンベア（４７）等を介して、二番還元コンベア（２３）に伝達され、次に該二番還元コンベア（２３）の末端から枝梗処理装置（１０１）へ伝達される。
二番還元コンベア（２３）内のオーガを駆動するためのコンベア駆動軸（６４）終端に設けられているベベルギア（６５）より、駆動プーリ（６６）、従動プーリ（６７）、伝動ベルト（６８）及びテンションプーリ（６９）からなるベルト伝動機構（７０）を経て、左右向き軸（５３）に動力を伝達し、枝梗処理胴（５２）を回転する構成としている。
【００３２】
この際、ベルト伝動機構（７０）は、機台（１）上に固定された脱穀部（４）と、機台（１）上に横外方への移動可能に装着された穀物タンク（７）との間個所で該個所の前後を通行不能なように閉鎖された機台（１）上空間個所に配設されると共に、脱穀部（４）及び穀物タンク（７）の何れよりも低い状態に装設される。従って、通常使用状態ではベルト伝動機構（７０）に人は近寄れないため、ベルト伝動機構（７０）の周囲が保護カバーで囲まれていなくても人がベルト伝動機構（７０）に接触する事態は生じないであり、一方、ベルト伝動機構（７０）や枝梗処理装置（１０１）の保守点検に際しては穀物タンク（７）を機台（１）の横外方へ移動させるのであり、これにより作業者は容易にベルト伝動機構（７０）や枝梗処理装置（１０１）の近傍に近寄れるのである。
【００３３】
次に前記制御弁（６０）及びこれに関連した機構について図８および図９を参照して説明する。
前記制御弁（６０）は、投入口（５８）の下方の、枝梗処理装置（１０１）の外枠を構成する処理ケース（５７）の内側面に設けられ、枝梗処理装置（１０１）内の二番物の送り速度を調節する。
制御弁（６０）は左右向き軸（５３）と直角方向に形成した弁部と、処理ケース（５７）に固定するため弁部と直角に配置した面よりなる固定部よりなり、該固定部の上部には回動部（７１）が、下部には支持部（７２）が形成されている。該支持部（７２）において、制御弁（６０）と処理ケース（５７）は、制御弁（６０）下部でボルトなどの固定手段で枢結されている。たとえば、制御弁（６０）下部と処理ケース（５７）にはボルト孔が設けられ、処理ケース（５７）内部から該ボルト孔にボルト（７２ａ）を挿通して、処理ケース（５７）外部からナット（７２ｂ）を締め付けることにより固定できるようにしている。
【００３４】
前記回動部（７１）において、制御弁（６０）の固定部の上部にボルト孔が開口されている。一方、処理ケース（５７）に前記ボルト（７２ａ）を中心とした円弧状の長孔（５７ａ）が穿設され、該長孔（５７ａ）にボルト（７１ａ）を挿通し、処理ケース（５７）内部からボルト（７１ａ）を挿通し、処理ケース（５７）外面にボルト（７１ａ）を突出させ、制御弁（６０）とボルト（７１ａ）をロックノブ（７１ｂ）で固定する。
【００３５】
制御弁（６０）は複数設けられており、連結手段となる連杆（７３）により連結されて、角度変更可能としている。つまり、連杆（７３）は処理ケース（５７）外面に配設され、該連杆（７３）には一定間隔をおいて複数のボルト孔（７３ａ）が穿設されている。該ボルト孔（７３ａ）に、処理ケース（５７）内面から突出した前記ボルト（７１ａ）を挿通し、処理ケース（５７）外部からロックノブ（７１ｂ）で締め付け、連杆（７３）を介して制御弁（６０）（６０）（６０）を処理ケース（５７）に固定している。
本実施例では、制御弁（６０）、連杆（７３）のボルト孔（７３ａ）、ロックノブ（７１ｂ）を各々三個配設したが、数は限定されるものではない。
【００３６】
このような構成にすれば、支持部（７２）のボルト（７２ａ）が回動支点となり、ボルト（７２ａ）を中心に制御弁（６０）が回動するので、制御弁（６０）の角度を調節することができる。また、複数の制御弁（６０）を連杆（７３）でつないでいるので、連杆（７３）を動かすことで、複数の制御弁（６０）を同時に同じ角度傾けることができる。また、連杆（７３）により長孔（５７ａ）を閉じることができて穀粒の漏れを防止できる。
【００３７】
また、制御弁（６０）の角度を変えれば、枝梗処理装置（１０１）内の二番物の送り速度を変えることができる。
枝梗付着の無い稲または麦刈取作業時は、制御弁（６０）の上部を投入口（５８）側に倒すことで、処理ケース（５７）内部の二番物をはやく送り出すことができ、二番物の損傷をなくすことができる。なお、これでもまだ枝梗除去能力が強い過ぎるときは枝梗処理胴（５２）を図６Ａに示す枝梗処理胴（５２）と交換装着する。
一方、枝梗の多い稲の時は、制御弁（６０）上部を放出口（６２）側に傾けることで、処理ケース（５７）内部に二番物を長くとどめて、二番物とチリをよくもむことで、枝梗を取り除き精選率を良くすることができる。
【００３８】
また枝梗処理装置（１０１）の中心線（処理ケース（５７）、左右向き軸（５３）の軸心線）は水平線より数度〜十数度程度の角度だけ出口側が下がるように配設している。この角度は放出を助長できる角度でよく、自然に転がり落ちるほど急な角度ではない。このように、枝梗処理装置（１０１）をやや斜めに配設することで、放出口（６２）が下がり、処理ケース（５７）内部の二番物が放出口（６２）から出やすくなり、作業終了時に二番物が処理ケース（５７）内部に残るのを防ぐことができる。また、処理ケース（５７）が傾斜しているので、掃除等がし易くなる。
【００３９】
さらに、ツースバー（５９）を、側面視において、処理ケース（５７）の最下部に位置しないように配設している。つまり、ツースバー（５９）が処理ケース（５７）の底部にあると、二番物がツースバー（５９）に詰まり、二番物が処理ケース（５７）内部に残りやすい。そのため、図１１に示すように、処理ケース（５７）の下側内部において、出来るだけ長い距離（Ｌ）だけ離れてツースバー（５９）を配設するとともに、左右向き軸（５３）の中心線を含む鉛直面と処理ケース（５７）の内周面と交わる位置から適当な距離離れてツースバー（５９）を配設して底部近傍にツースバー（５９）を配設しない構成としている。
このような構成にすることで、処理ケース（５７）内部に、二番物が残りにくく、また、清掃などがし易くなる。
【００４０】
また、枝梗処理胴（５２）を図６Ａに示すものに交換するときにはツースバー（５９）を取り外すことが必要となり、また処理ケース（５７）は必要に応じて内部の掃除をすることが必要となるのであり、これらに応じるため、ツースバー（５９）は取り外しまたは開閉できる構成としている。
即ち、図１１に示すように、脱穀側壁（５０）の外側となる処理ケース（５７）部分の下部には処理ケース（５７）の一部をなす回動部（７４）が、そして処理ケース（５７）上部に処理ケース（５７）の一部をなす取外し部（７５）が配設されている。回動部（７４）は、ツースバー（５９）、このツースバー（５９）を脱着可能に固定された処理ケース（５７）の一部、左右向き軸（５３）及び取付部（７４ｂ）で構成されている。
回動部（７４）の一端には回動軸（７４ａ）が配設され、ツースバー（５９）回動部（７４）は回動軸（７４ａ）を中心に回動する。また、処理ケース（５７）外面に、回動部取付プレート（５７ｂ）がボルトなどの固定手段で固設され、該回動部取付プレート（５７ｂ）に、回動軸（７４ａ）が固設されている。
【００４１】
回動部（７４）の他端には取付部（７４ｂ）が配設されており、該取付部（７４ｂ）は、処理ケース（５７）外面に突設されている取付部（５７ｃ）にボルト・ナットなどの固定手段で、着脱可能に固定されている。従って、取付部（５７ｂ）のボルトを外せば、回動部（７４）は回動軸（７４ａ）を中心に回動する。回動部（７４）を下方へ回動させた状態でツースバー（５９）は取り外される。
【００４２】
取外し部（７５）は、ツースバー（５９）、このツースバー（５９）を脱着可能に固定された処理ケース（５７）の一部、及び取付部（７５ａ）で構成されている。そして取付部（７５ａ）は取外し部（７５）の両端に配設されている。該取付部（７５ａ）（７５ａ）は、処理ケース（５７）外面に突設されている取付プレート（７５ｄ）（７５ｄ）にボルト・ナットなどの固定手段で着脱可能に固定されている。従って取付部（７５ａ）（７５ａ）のボルトを外せば、取外し部（７５）を簡単に取り外すことができ、このように取り外した状態でツースバー（５９）は取り外される。

And is directed downward just above a feed pan of an oscillating sorter provided below the screw-type handling cylinder.
[0004]
[Patent Document 1]
JP-A-9-294457
[0005]
[Problems to be solved by the invention]
In the above-mentioned conventional combine, since the second object discharged from the target discharge port of the branch stalk processing apparatus is concentrated on a local portion on the feed pan just below the target discharge port, the second target is dropped. Objects are difficult to spread evenly on the feed pan, which is a factor that reduces the sorting performance of the swinging sorter. Further, the processing drum rotated around the front-rear direction axis requires a large space in the handling room, which hinders the compactness of the machine body.
An object of the present invention is to provide a combine which can easily solve such a problem.
[0006]
[Means for Solving the Problems]
To achieve the above object, the present invention is as follows.
That is, the invention according to claim 1 is provided with a front-rearward screw-type handling cylinder in which a spiral member for transferring an object to be processed is fixed at a large part of the outer peripheral surface of the cylindrical body. In a combine in which a branch resection device for the second reductant is disposed near the lateral side of the trunk, the branch resection device is provided with an impeller for taking in a workpiece to be mounted attached to the forefront of the screw-type handling cylinder. It is arranged at the same position in the front-rear direction as the rear end.
According to the present invention, the impeller is rotated in the same shape as the screw-type handling cylinder to generate a relatively strong wind in the rotation direction of the screw-type handling cylinder and toward the rear of the fuselage. The processing object discharged from the processing apparatus is diffused in a relatively wide range on the feed pan.
[0007]
According to a second aspect of the present invention, there is provided a screw-type handling cylinder provided with a spiral member for transferring an object to be processed, which is fixed to a large part of the outer peripheral surface of the cylindrical body. In the combine in which a branch processing apparatus for the second reductant is disposed in the vicinity of the lateral side, the branch processing apparatus is disposed after the impeller for taking in the processing target attached to the foremost part of the screw-type handling cylinder. In addition to being disposed in the front-back direction position substantially the same as the end portion, the object discharge port of the branch stalk processing apparatus is opened substantially horizontally and horizontally toward the screw-type handling cylinder side.
According to this invention, the following operation can be obtained in addition to the operation according to the first aspect of the invention. In order to discharge substantially horizontally and horizontally toward the screw-type handling cylinder side, the object to be processed is placed on the feed pan by associating the discharge direction of the object with the flow direction of the wind generated by the impeller. It is even more diffused and effective.
[0008]
According to a third aspect of the present invention, there is provided a screw-type handling cylinder having a front-rear direction in which a spiral member for transferring an object to be processed is fixed at a large portion of the outer peripheral surface of the cylindrical body. And a processing cylinder of the branch vein processing apparatus is rotated around a left-right axis in a combine having a branch vein processing apparatus for the second reductate disposed near the lateral side of the combine.
According to this invention, since the processing cylinder of the branch incision processing apparatus is rotated around the left-right axis, the space occupied by the branch incision processing apparatus in the vicinity of the screw-type handling cylinder is such that the processing cylinder is rotated around the front-rear axis. It becomes smaller than that which is rotated to, so that the branch stalk processing device is less likely to become an obstacle to the flow of the wind generated by the impeller, and the object to be processed is more extensively and effectively on the feed pan. In addition to being diffused, it also contributes to making the right and left widths of the body (particularly the threshing unit) where the above-described branching device is present, and also enables the processing of the object in the branching device. A structure for discharging the liquid in a substantially horizontal direction toward the screw-type handling cylinder is easily realized.
[0009]
In addition, the invention according to claim 4 includes a front-rearward screw-type handling cylinder in which a spiral member for transferring an object to be processed is fixed in a large part of the outer peripheral surface of the cylindrical body, in the handling chamber, In a combine in which a branch resection device for a second reductant is disposed near the lateral side of the screw-type handling cylinder, the branch-piece processing device is mounted on a forefront of the screw-type handling cylinder. Along with the rear end of the impeller for substantially the same position in the front-rear direction, the processing end side portion of the processing case of the branch vein processing apparatus that surrounds the processing drum peripheral surface is located in the handling room, and In this embodiment, the upper half of the processing cylinder is not covered.
According to this invention, the following operation can be obtained in addition to the operation according to the first aspect of the present invention, that is, the processing of the range surrounding the processing cylinder peripheral surface in the processing case of the branch vein processing apparatus. Since the terminal end portion is located in the processing chamber and does not cover substantially the upper half range of the processing cylinder, the grains threshed in the processing chamber are placed in the processing case of the processing terminal side portion. Even if it falls, the processing cylinder discharges from the processing case on the processing end side portion, and therefore, kernels threshed in the handling room do not accumulate on the processing case.
[0010]
According to a fifth aspect of the present invention, there is provided a screw-type handling cylinder having a front-rear direction in which a spiral member for transferring an object to be processed is fixed at most of the outer peripheral surface of the cylindrical body. In a combine in which a branch processing apparatus for the second reductate is disposed near the lateral side of the combine, the branch processing apparatus is provided on the left side of the screw-type handling cylinder on the upper side in the rotation direction of the screw-type handling cylinder. At the same time, the processing cylinder of the branch stalk processing apparatus is configured to rotate around a left-right axis.
According to the present invention, the following effect can be obtained in addition to the effect of the invention according to claim 3, namely, the branch-pea processing device is formed by the screw-type handling cylinder on the left and right sides of the screw-type handling cylinder. By providing on the upstream side in the rotation direction of the handling cylinder, the wind in the rotation direction of the handling cylinder generated by rotation of the screw-type handling cylinder causes the object to be processed emitted from the branch stalk processing apparatus to flow on the feed pan. In this way, it is possible to spread the light more effectively over a wider area.
[0011]
According to a sixth aspect of the present invention, there is provided a screw-type handling cylinder having a front-rearward-type screw handling cylinder on which a helical member for transferring an object to be processed is fixed at most of the outer peripheral surface of the cylindrical body.

It is located.
According to this invention, the object to be processed is dropped on the position near the starting end of the feed pan because the object to be processed is dropped on the feed pan after the object to be processed is discharged by the branch stalk processing apparatus. Processing is performed in a relatively long front-rear range until reaching the end, and the leveling of the layer thickness is promoted.
[0012]
According to a seventh aspect of the present invention, there is provided a front-rearward screw-type handling cylinder in which a spiral member for transferring an object to be processed is fixed at a large portion of the outer peripheral surface of the cylindrical body. Immediately below the trunk, a swing sorter with a chaff sheave connected to the rear side of the feed pan, and near the lateral side of the screw-type handling cylinder, a branch processing apparatus for second reductate is disposed. In the combine, the object discharge port of the branch stalk processing apparatus is located right above the position of the swing sorter near the start end of the feed pan, and between the rear end of the feed pan and the front end of the chaff sheave. The selected wind flows upward from the lower side of the air passage through the air passage formed in the above.
According to this invention, the following operation can be obtained in addition to the operation according to the invention described in claim 6, namely, through the air passage formed between the rear end of the feed pan and the front end of the chaff sheave. Since the sorting wind flows from the lower side to the upper side of the air passage, the processing target discharged from the processing target discharge port is scattered by the sorting wind and is more effective above the feed pan or the like. Will be spread.
[0013]
According to an eighth aspect of the present invention, in the combine according to any one of the first to seventh aspects, the branch incision processing cylinder of the branch incision processing apparatus can be exchangeably mounted with another one having a different processing effect. It is.
According to the present invention, cereal grains, such as rice, to which branch stalks are liable to adhere are strongly treated by a strong stalk processing cylinder. It will be lightly processed by the barn processing cylinder.

On the inner surface of the processing case (57), a tooth bar (fixed processing blade) (59) and a control valve (60) to be described later are protruded.
6A has a spiral member (61) fixed to the outer peripheral surface thereof. In this embodiment, the branch stalk processing cylinder (52) shown in FIG. The branch bar removal ability is inferior to that of the torso (52). When this is mounted in the processing case (57), the tooth bar (59) is removed.
[0025]
As shown in FIGS. 7 and 9, the processing case (52) positions the processing end side portion (57a) in the range surrounding the peripheral surface of the branch stalk processing cylinder (52) in the handling room (27); The configuration is such that it does not cover substantially the upper half area of the branch branch processing cylinder (52). Therefore, the paddy or the like that has leaked from the receiving net (30) may fall from above into the inside of the processing end portion (57a) of the processing case (57). The workpiece is transported in a substantially horizontal direction toward the screw-type handling cylinder (5) inside the processing case (57) by the action of transferring the workpiece by the processing cylinder (52). Here, if the processing end side portion (57a), which is the processing case (57) located in the handling room (27), surrounds the entire periphery of the branch incision processing cylinder (52), the receiving net (30). Paddy or the like that has leaked from the container may accumulate on the upper surface of the processing case (57), but as described above, the processing case (57) Since the upper half area is not covered, there is no accumulation of paddy and waste.
[0026]
Substantially the entire left end surface of the processing case (57) is formed as a processing object discharge port (62), and the discharge port (62) is connected to a receiving net (30) at the front end of the threshing unit (4). It is arranged near the lower side and facing above the feed pan (36) of the swinging sorter (31). Then, from a position displaced rearward by an appropriate distance (L1) from the lowest position of the processing end side part (57a) of the processing case (57) near the processing object discharge port (62) as shown in FIG. A support rod member (63) is provided, and a tip of a left-rightward shaft (53) that forms a rotation center of the branch stalk processing cylinder (52) is rotatably supported above the support rod member (63). At this time, since the support rod member (63) is deviated by an appropriate distance (L1), it prevents movement of paddy or the like toward the processing target discharge port (62) on the lowest part in the processing case (57). Therefore, the paddy and the like do not remain in the processing case (57).
[0027]
In the above configuration, the flow of the second product from the second reduction conveyor (23) will be described. The second product is put into the branch stalk processing apparatus (101) from the input port (58), and then the branch product is fed. With the rotation of the processing cylinder (52), it is moved to the left side of the body with the help of the intake blade (54), and subsequently, the processing teeth (55) provided on the outer circumference of the branch processing cylinder (52), and the branch stem reduction The toothed bar (59) protruding from the inner surface of the processing case (57) constituting the outer frame of the apparatus (101) is transported to the vicinity of the processing object discharge port (62) while removing branch stalks. With the aid of the splashing blade (56), the blade is springed out from the discharge port (62) toward the screw-type handling cylinder (5), and the front end of the threshing unit (4), that is, the feed pan (36) Fall onto the front surface.
[0028]
5 and 6, the branch cane processing cylinder (52) is arranged in the left-right direction orthogonal to the body traveling direction, and the rotation direction (f2) of the branch cane processing cylinder (52) is It is clockwise as viewed from the left side in the advancing direction of the body, and the rotational speed of the branch stalk processing cylinder (52) is about 500 rpm.
The second product input from the input port (58) is moved from the inner end of the processing case (57) toward the processing target discharge port (62) by the rotation of the branch stalk processing cylinder (52). When the water is discharged from the discharge port (62) by the movement, it is directed in the direction of the flow of wind due to the rotation of the screw-type handling cylinder (5), that is, in the horizontal direction on the screw-type handling cylinder (5) side. It is swept toward the rear of the aircraft and scattered over a wide area on the feed pan (36).
[0029]
On the other hand, as shown in FIG. 12, since the air passage (t) is formed between the rear end (p2) of the feed pan (36) and the front end (p3) of the first chaff sheave (37), The sorted wind sent out from the air passage (42) flows from the lower side to the upper side of the wind passage (42) through the wind passage (42). ), The grains and the like discharged from the processing object discharge port (62) are more evenly scattered.
[0030]
In this way, uniform diffusion of the second product on the upper surface of the feed pan (36) or the like is secured, local accumulation of the second product on the feed pan (36) or the like is prevented, and The rice paddy layer has a uniform thickness as a whole and becomes thin, and the processing in the feed pan (36) and the first chaff sheave (37) is efficiently performed, and the leakage of the kernel to the first conveyor (46) is performed. The lowering is performed accurately, and the sorting performance is improved.
[0031]
Next, a power transmission configuration to the branch stalk processing apparatus (101) will be described with reference to FIGS. 2, 3, 8, and 9. FIG.

[0032]
At this time, the belt transmission mechanism (70) includes a threshing unit (4) fixed on the machine base (1) and a grain tank (7) mounted on the machine base (1) so as to be movable laterally outward. ), Which is disposed in a space above the machine base (1) which is closed so that it cannot pass before and after the place, and which is lower than any of the threshing unit (4) and the grain tank (7). Installed in state. Therefore, in a normal use state, a person does not approach the belt transmission mechanism (70). Therefore, even if the periphery of the belt transmission mechanism (70) is not surrounded by the protective cover, a situation in which a person comes into contact with the belt transmission mechanism (70) does not occur. On the other hand, when performing maintenance and inspection of the belt transmission mechanism (70) and the branch stalk processing device (101), the grain tank (7) is moved laterally outward of the machine base (1). The person easily approaches the vicinity of the belt transmission mechanism (70) and the branch stalk processing device (101).
[0033]

In the rotating part (71), a bolt hole is opened above the fixed part of the control valve (60). On the other hand, an arc-shaped long hole (57a) centering on the bolt (72a) is formed in the processing case (57), and the bolt (71a) is inserted through the long hole (57a) to form the processing case (57). The bolt (71a) is inserted from the inside, the bolt (71a) is projected from the outer surface of the processing case (57), and the control valve (60) and the bolt (71a) are fixed by the lock knob (71b).
[0035]
A plurality of control valves (60) are provided and are connected by a connecting rod (73) serving as connecting means so that the angle can be changed. That is, the connecting rod (73) is disposed on the outer surface of the processing case (57), and the connecting rod (73) is provided with a plurality of bolt holes (73a) at regular intervals. The bolt (71a) protruding from the inner surface of the processing case (57) is inserted into the bolt hole (73a), tightened with a lock knob (71b) from the outside of the processing case (57), and the control valve is connected via the connecting rod (73).

Also, the center line (the processing case (57), the axis of the left-right axis (53)) of the branch stalk processing apparatus (101) is disposed so that the exit side is lowered by an angle of about several degrees to several tens degrees from the horizontal line. ing. This angle can be an angle that facilitates release and is not steep enough to roll down naturally. In this way, by arranging the branch stalk processing apparatus (101) slightly obliquely, the discharge port (62) is lowered, and the second product inside the processing case (57) is easily discharged from the discharge port (62). It is possible to prevent the second product from remaining inside the processing case (57) at the end of the work. In addition, since the processing case (57) is inclined, cleaning or the like becomes easy.
[0039]
Further, the tooth bar (59) is disposed so as not to be located at the lowermost part of the processing case (57) in a side view. In other words, when the tooth bar (59) is at the bottom of the processing case (57), the second product is stuck in the tooth bar (59), and the second product tends to remain inside the processing case (57). Therefore, as shown in FIG. 11, the tooth bar (59) is disposed at a distance (L) as long as possible inside the lower side of the processing case (57), and the center line of the horizontal shaft (53) is aligned. The tooth bar (59) is disposed at an appropriate distance from the position where the vertical plane including the vertical plane and the inner peripheral surface of the processing case (57) intersect, and the tooth bar (59) is not disposed near the bottom.
With such a configuration, it is difficult for the second article to remain inside the processing case (57), and it is easy to perform cleaning.
[0040]

Therefore, when the bolt of the mounting portion (57b) is removed, the rotating portion (74) rotates around the rotating shaft (74a). The tooth bar (59) is removed with the rotating part (74) rotated downward.
[0042]
The removal part (75) is composed of a tooth bar (59), a part of the processing case (57) to which the tooth bar (59) is detachably fixed, and an attachment part (75a). And the attachment part (75a) is arrange | positioned at both ends of the removal part (75). The mounting portions (75a) (75a) are detachably fixed to mounting plates (75d) (75d) projecting from the outer surface of the processing case (57) by fixing means such as bolts and nuts. Therefore, if the bolts of the attachment portions (75a) (75a) are removed, the removal portion (75) can be easily removed, and the tooth bar (59) is removed in such a removed state.
