【０００１】
【発明が属する技術分野】
本発明は、圃場の穀稈を刈取部で刈取り、脱穀部に搬送して脱穀するコンバインに関する。
【０００２】
【従来の技術】
コンバインの刈取部は、エンジンからの動力が最初に伝達される刈取入力軸を内蔵する刈取入力ケースが、走行機体のシャーシから脱穀部の前側に立上げる軸受台に左右の半割軸受によって回転自在に軸受けされ、脱穀部の直前にて機体左右方向に支持され、前記刈取入力軸に連動連結される縦伝動軸を内蔵する縦伝動ケースが、前記刈取入力ケースの外面から前斜下方に向けて一体延設され、前記縦伝動軸に連動連結される横伝動軸を内蔵する横伝動ケースの中間外面が、前記縦伝動ケースの先端に一体連結され、横伝動ケースを機体左右方向に支持し、後部が横連結フレームによって一体連結された刈取条数に応じた複数本一体の刈取フレームの後端部を前記横伝動ケースに一体連結し、刈取フレームを横伝動ケースから機体前方に向けて一体延設している。そして、前記刈取フレームに刈取条数に応じた分草引起装置、掻込装置、刈刃装置が取付けられ、圃場の未刈穀稈を、分草後に引起しながら掻込み、その掻込時に未刈穀稈の株元を切断して刈取るようになっている。刈取穀稈は、株元部がチェンによって挟持搬送され、穂先部もタインによって係止搬送されて脱穀部のフィードチェンの搬送始端部に受継搬送されるようになっている。この刈取部は、走行機体のシャーシと前記縦伝動ケースとの間に張架された油圧シリンダによって、刈取入力ケースを中心に（支点に）上下方向に回動できるようになっている。（例えば、特許文献１，２参照。）
【０００３】
また、走行機体のシャーシの左半分に脱穀部が搭載される場合には、そのシャーシの右半分に穀物タンクが搭載され、その穀物タンクの前側に運転席及び運転操作部を有する運転台が配設され、その運転台の左横一側で脱穀部の前方に前記刈取部が配設される。このような機体レイアウトにおいて、フィードチェンは脱穀部の左側に張架され、搬送始端部が刈取部の後部左側に延設され、刈取穀稈の株元部を刈取部の後部左側でフィードチェンの搬送始端部に受継ぐようになっている。（例えば、特許文献１，２参照。）
【０００４】
尚、走行機体のシャーシの右半分に脱穀部が搭載される場合には、上記の機体レイアウトが左右逆になり、刈取穀稈の株元部は刈取部の後部右側でフィードチェンの搬送始端部に受継がれる。
【０００５】
ところで、従来のコンバインの刈取部では、この上下回動支点となる刈取入力ケースに内蔵された刈取入力軸の運転席側の端部（フィードチェン側の端部と反対側の端部、即ち機体外側の端部と反対側の機体内側の端部）を刈取入力ケースから突出させ、その突出端部に大径の入力プーリを設け、刈取入力軸の運転席側の端部に対してエンジンからの動力がベルト伝動によって最初に伝達されていた。（例えば、特許文献１，２，３参照。）
【０００６】
また、刈取入力軸への伝動経路は２系統あり、その２系統の伝動経路のうち、一方の伝動経路を接続し他方の伝動経路を切断して刈取部を駆動しており、一方の伝動経路は、刈取部の駆動速度を車速（走行速度）に同調させて変速させるためにエンジンからの動力を走行用無段変速装置を経て刈取入力軸の運転席側の端部に伝達するもので、通常の刈取作業時にはこの伝動経路からの動力でもって刈取部が駆動され、他方の伝動経路は、畦際での刈終わり時に刈取部にある穀稈を脱穀部へ送込む流込作業を行う場合や圃場の隅刈作業を行う場合、その他圃場の未刈部分の一部に倒伏穀稈があり、その部分を車速を低速にして刈取る場合に、刈取部を車速と同調させずに一定速度で駆動するために脱穀部への伝動系から刈取入力軸の運転席側の端部に動力を伝達するものである。（例えば、特許文献３参照。）
【０００７】
上記のように前記刈取入力軸が内蔵される刈取入力ケースは、この両端部が、走行機体のシャーシから脱穀部の前側に立上げる軸受台に左右の半割軸受によって回転自在に軸受けされ、それぞれの半割軸受のうち軸受台側に取付ける一方の半割の軸受本体に他方の半割の軸受蓋を締付けているボルトを取外し、刈取入力軸の運転席側の端部に設けた入力プーリに掛けられている伝動ベルトを外し、縦伝動ケースに油圧シリンダのピストンロッド先端を連結している連結ピンを引抜くことによって、走行機体から刈取部を取外すことができるようになっている。また左右の半割軸受のうち、刈取入力ケースのフィードチェン側と反対側の端部を軸受けするものの軸受本体は軸受台に固着され、刈取入力ケースのフィードチェン側の端部を軸受けするものの軸受本体は軸受台のボスに回転自在に嵌合される垂直軸の上部に固着され、刈取入力ケースのフィードチェン側と反対側の端部の軸受けを開放し、刈取入力ケースのフィードチェン側の端部のみを軸受けした状態で、刈取入力軸の運転席側の端部に設けた入力プーリに掛けられている伝動ベルトを外し、縦伝動ケースに油圧シリンダのピストンロッド先端を連結している連結ピンを引抜くことによって、刈取部を前記垂直軸を中心に（支点に）装着位置と機体外側の開放位置との間で左右方向に回動できるようになっている（刈取部をサイドオープンできるようになっている）。このように、刈取部を走行機体から取外した状態、又はサイドオープンさせた状態で、刈取部や走行機体側のメンテナンスなどを行えるようになっている。（例えば、特許文献２参照。）

【発明が解決しようとする課題】
従来のコンバインの刈取部では、上記したように、エンジンからの動力が、刈取部の上下回動支点となる刈取入力ケースに内蔵された刈取入力軸の運転席側の端部に対してベルト伝動によって伝達されるため、刈取部を走行機体から取外すとき、又はサイドオープンするときの、伝動ベルトの掛け外しなどが困難であった。
【００１０】
そこで、刈取部を走行機体から取外すとき、又はサイドオープンするときの、伝動ベルトの掛け外しなどを容易に行わせ、メンテナンス性の向上を図ることができるように、エンジンからの動力を刈取部へ適正に伝達するコンバインを提供することを、本発明の主たる目的としている。
【００１１】
【課題を解決するための手段】
上記の目的を達成する本願の請求項１に係る発明は、エンジンからの動力を、刈取部の上下回動支点となる刈取入力ケースに内蔵された刈取入力軸のフィードチェン側の端部に伝達するコンバインであって、前記刈取入力ケースの両端を走行機体に回転自在に軸受けする左右の半割軸受のうち、刈取部の左右回動支点となる垂直軸を有する一方の半割軸受に、カウンタ軸と一方の歯車を内蔵するカウンタケースを一体形成し、カウンタ軸上の歯車の一部を軸受面に突出させる一方、他方の歯車を前記刈取入力軸上に設けて軸管のフィードチェン側の端部に内蔵し、軸受面に突出させたカウンタ軸上の歯車の一部を挿入して前記刈取入力軸上の歯車と噛合わせる歯車挿入孔を、軸管のフィードチェン側の端部の被軸受部に開口形成したことを特徴とする。
【００１２】
請求項１に係る発明によれば、刈取部の機外側に入力プーリが設けられるから、刈取部を走行機体から取外すとき、又はサイドオープンするとき、伝動ベルトの掛け外しを機外側から容易に行え、結果、メンテナンス性が向上する。
しかも、カウンタ軸と刈取入力軸との間の伝動を、刈取部の左右回動支点となる垂直軸を有する一方の軸受部の内側で噛合う歯車によって行うから、走行機体に対する刈取部の装着／取外し及びカウンタ軸と刈取入力軸との間の伝動経路の接続／切離しを同時に行えると共に、専用の伝動ケースを設けることなく密閉空間内に歯車を収容でき、藁屑や塵埃が歯車に付着するのを防止でき、走行機体に対する刈取部の装着／取外しを容易に行え、メンテナンス性を向上させながら、エンジンからの動力を、刈取部の上下回動支点となる軸管に内蔵された刈取入力軸のフィードチェン側の端部に適正に伝達することができる。
【００１３】
本願の請求項２に係る発明は、前記請求項１に係る発明に加え、前記刈取入力軸のフィードチェン側の端部近傍にカウンタ軸を設け、該カウンタ軸を走行機体側に軸受けし、エンジンからの動力をカウンタ軸に対してベルト伝動によって伝達し、カウンタ軸と刈取入力軸との間の伝動を歯車によって行うことを特徴とする。
【００１４】
請求項２に係る発明によれば、走行機体側に入力プーリが設けられるから、刈取部を走行機体から取外すとき、伝動ベルトの掛け外しが不要になり、結果、メンテナンス性が向上する。また走行機体側に入力プーリ及びそれを軸支するカウンタ軸が設けられるから、刈取部の上下回動位置に拘わらず入力プーリを軸支するカウンタ軸とそれに対する出力プーリを軸支する軸の軸間距離を一定維持できると共に、カウンタ軸と刈取入力軸との間の伝動を歯車で行うから、刈取部の上下回動位置に拘わらずカウンタ軸から刈取入力軸への動力伝達経路を接続維持でき、刈取部の上下回動位置に拘わらずエンジンからの動力を、刈取部の上下回動支点となる軸管に内蔵された刈取入力軸のフィードチェン側の端部に適正に伝達することができる。
【００１５】
本願の請求項３に係る発明は、前記請求項１に係る発明に加え、前記刈取入力軸のフィードチェン側の端部近傍にカウンタ軸を設け、エンジンからの動力をカウンタ軸に対してベルト伝動によって伝達し、カウンタ軸と刈取入力軸との間の伝動を歯車によって行うことを特徴とする。
【００１６】
請求項３に係る発明によれば、刈取入力軸のフィードチェン側の端部に直接大径の入力プーリを設け、エンジンからの動力をベルト伝動によって直接刈取入力軸に伝達するのではなく、刈取入力軸とは別のカウンタ軸上に入力プーリを設け、エンジンからの動力をベルト伝動によって一旦カウンタ軸に伝達し、そのカウンタ軸から刈取入力軸に歯車伝動によってエンジンからの動力を間接的に伝達するから、大径の入力プーリが刈取部から脱穀部のフィードチェンへの穀稈搬送の障害になるのを防止でき、エンジンからの動力を、刈取部の上下回動支点となる軸管に内蔵された刈取入力軸のフィードチェン側の端部に適正に伝達することができる。
【００１９】

【００２４】
刈刃３２は、可動刃を刈幅の中央部で分割し、左右の可動刃３２を相反する方向に往復運動させ、振動を相殺するようにしたもので、横伝動軸４１の左端部より少し内側からベベルギヤを介して左側の刈刃駆動軸であるクランク軸５２ａを上向きに立上げると共に、横伝動軸４１の右端部よりベベルギヤを介して右側の刈刃駆動軸であるクランク軸５２ｂを上向きに立上げ、左右のクランク軸５２ａ，５２ｂを横伝動ケース２２から上方に突出させ、横伝動軸４１から左右の可動刃３２の動力を取出すように構成している。
