【発明の属する技術分野】
本発明は、コンバインの刈取部に係るものであり、特に圃場の穀稈を分草する分草装置に係るものである。
【０００２】
【従来技術】
従来、最前方位置に左右に分草具を複数並設し、この分草具の内の未刈側前方位置に、上方に設けた取付部分を中心に上下回動する補助分草装置を設けた構成が記載されている（特許文献１参照）。
【０００３】

実公昭６２−３５３０９号公報（３頁、図１、図２）
【０００４】
【発明が解決しようとする課題】
前記公知例の補助分草装置は、単に分草する作用が記載されているだけで、補助分草装置の具体的作用は記載されていない。
しかし、公知例の構成では、補助分草装置は引起装置の上部に回動自在に設けた軸棒部材の先端に設けているため、軸棒部材に穀稈が絡むという課題がある。また、右端側に設けていないので、機体進行方向の左右両側の穀稈群の中央に進んで行う刈取作業（中割）や畦際の刈取作業のとき、十分な分草効果が期待できない。
本願は、少なくとも、右端に補助分草装置を摺動上下自在に設けて、操作性と作業性を向上させた刈取部を提供するものである。
【０００５】
【発明の目的】
中割や畦際の穀稈の刈取作業の容易化。
【０００６】
【課題を解決するための手段】
本発明は、最前方位置に左右に複数並設した圃場の穀稈を分草する分草装置１０と、該分草装置１０の後方に複数並設した穀稈を引き起こすラグ式引起装置１１と、引起装置１１の後側に設けた穀稈を切断する刈刃１２と、該刈刃１２の上方から後方に穀稈を搬送する穀稈搬送装置４６とを有する刈取部４を機体前部に設け、前記左右に並設した分草装置１０の内の少なくとも右端の分草装置１０の前側には補助分草装置１５を設け、補助分草装置１５の下側補助分草体１６は分草装置１０に固定状態に取付け、下側補助分草体１６には上側補助分草体１７を摺動上下自在に取付けたコンバインの刈取部としたものであり、走行装置２により圃場を走行し、刈取部４の分草装置１０が圃場の穀稈を分草し、分草された穀稈は引起装置１１により引き起こされ、引き起こされた穀稈が刈刃１２により切断され、穀稈搬送装置４６により穀稈供給搬送装置４９に穀稈を搬送し、穀稈供給搬送装置４９により脱穀室に穀稈が供給されて脱穀する。
この場合、上側補助分草体１７を下側補助分草体１６に対して上下させることで、穀稈に当たる接触面積および上端高さを変更自在とし、圃場の穀稈の状態に応じた分草効果を期待できると共に、走行方向の目印として作用する。
特に、機体進行方向の左右両側の穀稈群の中央に進んで行う刈取作業や畦際の刈取作業のとき上側補助分草体１７を上動させると、株元側から穂先に近い高さまで分草し、また、通常の刈取作業のときに上側補助分草体１７を下動させると、前方視界の障害にならず、作業性を低下させない。
本発明は、前記補助分草装置１５は、上側補助分草体１７を下側補助分草体１６の内側を上下するように設けて構成したコンバインの刈取部としたものであり、上側補助分草体１７は下側補助分草体１６の内側で上下する。
本発明は、前記上下する上側補助分草体１７は、右分草板２８と左分草板２９とに左右に分割し、右分草板２８と左分草板２９は夫々単独で上下するように構成したコンバインの刈取部としたものであり、上側補助分草体１７の右分草板２８と左分草板２９は夫々単独で上下し、例えば、中割の刈取作業のときには右分草板２８と左分草板２９の両方を上動させ、畦際の刈取作業のときは、右分草板２８と左分草板２９の内の畦側の右分草板２８を下動させることにより、畦と補助分草装置１５の先端との位置関係を容易に視認しつつ、左分草板２９を高く上動させ、ることで、分草効果を期待でき、操作性と作業性とを両立させられ、通常の刈取作業のときは上側補助分草体１７全体を下降させることで、操縦部７からの視界を良好にする。
【０００７】
【発明の効果】
請求項１の場合、右側の補助分草装置１５により圃場の植立穀稈を分草できる。
請求項２の場合、前記効果に加えて、補助分草装置１５の上側補助分草体１７の上下動構成が穀稈の分草に障害とならず、補助分草装置１５周辺の視界を良好にできる。
請求項３の場合、前記効果に加えて、圃場や穀稈の状況に最適に対応した分草効果を期待できる。
【０００８】
【発明の実施の形態】
本発明の実施例を図により説明すると、１は機体フレーム、２は該機体フレーム１の下方位置に設けた走行装置、３は機体フレーム１の上方位置に設けた脱穀装置、４は脱穀装置３の前側に設けた刈取部、７は操縦部である。
前記刈取部４は、最先端位置に圃場の穀稈を分草する分草装置１０を左右に並設し、各分草装置１０の後側に分草装置１０が分草した穀稈を引起す引起装置１１を設け、引起装置１１の後側には刈刃１２を設けている。
前記分草装置１０は、左右中間位置が高い断面形状であって左右傾斜分草面１３を形成し、左右傾斜分草面１３は側面視後方に至るに従い高く形成し、分草装置１０の下部は前後方向の分草杆１４に固定する。分草杆１４は軸棒形状に形成し、分草装置１０が分草した穀稈の株元側を引き続き分草する作用を奏する。
【０００９】
左右に並設した分草装置１０の内の少なくとも右端の分草装置１０の前側には、上下に分割した補助分草装置１５を設け、補助分草装置１５の下側補助分草体１６は分草装置１０に固定状態に取付け、下側補助分草体１６には上側補助分草体１７を上下自在に取付ける。
補助分草装置１５は、上側補助分草体１７を上下させることで、穀稈に当たる接触面積および上端高さを変更自在とし、圃場の穀稈の状態に応じた分草効果を期待できると共に、走行方向の目印としての作用効果も向上し、操作性および作業性を向上させる。
特に、機体進行方向の左右両側の穀稈群の中央に進んで行う刈取作業や畦際の刈取作業のとき、上側補助分草体１７を上動させると、操作性および作業性を向上させる。
【００１０】
また、通常の刈取作業のときには上側補助分草体１７を下動させると、前方視界の障害にならず、作業性を低下させない。
補助分草装置１５は、下側補助分草体１６の内面下部に平板状のステー１８の左右両端を固定し、ステー１８と分草装置１０とをピン形状の下側取付部材１９によりに固定し、下側補助分草体１６の上部内面には左右方向の上部ステー２０の左右両端を固定し、上部ステー２０と分草装置１０の上部とを上側固定部材２１により固定する。
したがって、下側取付部材１９および上側固定部材２１は勿論のこと、ステー１８および上部ステー２０も補助分草装置１５の内側に位置するので、補助分草装置１５の分草面に凹凸がなく、円滑確実に作用し、分草姿勢を乱さない。
【００１１】
この場合、上部ステー２０に前後方向の長孔２２を形成し、分草装置１０に左右方向の長孔２３を設けたステー２４を設け、各長孔２２と長孔２３に夫々止着部材２５を介して上側固定部材２１により連結すると、補助分草装置１５全体の前後傾斜および左右位置を下側取付部材１９中心に前後および左右回動させて調節でき、補助分草装置１５と分草装置１０との位置関係を変更することで、作業者の着座位置に応じた分草装置１０の位置とし、分草装置１０の視認性を向上させて操作性を向上させられる。
上側補助分草体１７は、右分草板２８と左分草板２９との前端を一体的に形成し、右分草板２８および左分草板２９の後端は自由端に形成して平面視三角形の二辺の形状に形成する。下側補助分草体１６の内面（後面）側の左右両側には縦長の摺動溝３０を形成し、上側補助分草体１７の外面が下側補助分草体１６の内面に摺接するようにして上側補助分草体１７の後端を摺動溝３０に嵌合させる。３１は右分草板２８および左分草板２９の外面上部に設けた把手兼ストッパであり、下側補助分草体１６より外側に突き出て下側補助分草体１６の上縁に係合する。
【００１２】
したがって、上側補助分草体１７は下側補助分草体１６の後側を上下し、上側補助分草体１７は下動させると下側補助分草体１６の後側に格納され、この点でも、補助分草装置１５の分草面に凹凸を発生させず、分草姿勢を乱さない。
３２はロック手段であり、下側補助分草体１６の上部位置に内外（上側補助分草体１７の板面に対して交差方向）に変位する板バネ等の弾性部材３３の基部を固定し、弾性部材３３の先端側は自由端に形成し、弾性部材３３の先端側にはピン形状の係合部材３４を設ける。係合部材３４は弾性部材３３が弾性復帰すると、上側補助分草体１７に設けた係合孔３５に外側から係合し、上側補助分草体１７の下動を阻止する。係合部材３４を係合孔３５から離脱させ、上側補助分草体１７を手動操作により押し下げると、上側補助分草体１７は下動する。
【００１３】
３６は弾性部材３３の先端に形成したレバー部であり、レバー部３６を引くと係合部材３４は係合孔３５から離脱し、レバー部３６を離すと、係合部材３４は係合孔３５に係合する。
【００１４】
しかして、下側補助分草体１６に対して上下する上側補助分草体１７は、その右分草板２８と左分草板２９を左右に分割し、夫々単独で上下自在に構成する。したがって、畦際の刈取作業のとき、上側補助分草体１７の内の畦側の右分草板２８を下動させることにより、畦と補助分草装置１５の先端との位置関係を容易に視認しつつ、左分草板２９を高く上動させることで、分草効果を期待でき、操作性と作業性とを両立させられる。
この場合、左分草板２９の右縁は補助分草装置１５の左右中央の稜線（平面視の頂点）稜線４０位置より右側に折り返して折返部４１に形成すると、穀稈と左分草板２９との当接面が連続した平面視円弧面に形成でき、穀稈の穂を扱いて脱粒させることなく、分草する。
【００１５】
前記左分草板２９の折返部４１と下側補助分草体１６の内面との間には所定の隙間を設けて前側摺動溝４２を形成し、前側摺動溝４２に右分草板２８の前縁を摺動自在に嵌合させる。
したがって、左分草板２９の折返部４１と右分草板２８の前縁の摺動部分は何れも下側補助分草体１６の内側に位置することになり、穀稈の分草の障害になることはない。
この場合、ロック手段３２は、前後一対の係合部材３４を有する弾性部材３３を下側補助分草体１６の上部位置に設け、係合部材３４は左分草板２９の折返部４１に形成した係合孔３５と、右分草板２８に形成した係合孔３５の夫々に独立して係合し、右分草板２８と左分草板２９を独立して上下させて保持できる。
【００１６】
しかして、前記上側補助分草体１７の右分草板２８と左分草板２９の夫々は、操縦部７より上下操作可能に構成すると、操作性が向上して好適である。実施例では、右分草板２８と左分草板２９の夫々には、夫々上下操作ハンドル４５を設け、上下操作ハンドル４５は最も右分草板２８と左分草板２９を下げた位置でも操縦部７より届くようにする。
この場合、ロック手段３２は、操縦部７から操作可能に構成すると、操作性が向上して好適である。一例を示すと、ベルクランク状の作動部材４６を上側補助分草体１７の内面側に軸４７により回動自在に取付け、作動部材４６の一端には前記係合部材３４を設け、作動部材４６の他端には上下操作ハンドル４５に設けた操作レバー４８に一端を接続した操作伝達部材４９の他端を係止する。
【００１７】
上側補助分草体１７の右分草板２８と左分草板２９の夫々は、上下操作ハンドル４５の操作レバー４８を操作して、下側補助分草体１６に設けた係合孔３５から係合部材３４を離脱させ、この状態で、上下操作ハンドル４５により上側補助分草体１７を引き上げ、所定高さの下側補助分草体１６に設けた係合孔３５に係合部材３４を合わせると、係合部材３４が内側から係合孔３５に係合してロック手段３２はロックし、上側補助分草体１７の下動を停止させる。
反対に、上下操作ハンドル４５の操作レバー４８を操作して、下側補助分草体１６に設けた係合孔３５から係合部材３４を離脱させて、ロック手段３２をアンロックさせると、上側補助分草体１７を上下操作ハンドル４５による手動操作の押し下げが可能になって、上側補助分草体１７は下動する。
【００１８】
この場合、上側補助分草体１７の右分草板２８と左分草板２９の夫々は夫々の上下操作ハンドル４５の操作レバー４８を操作すると、独立して右分草板２８と左分草板２９の上下操作可能である。
なお、係合孔３５は下側補助分草体１６に上下に複数設けると、所望高さでロック手段３２をアンロックさせて上側補助分草体１７を保持する。
【００１９】
しかして、補助分草装置１５は、実施例では左右に並設した分草装置１０のうちの右端の分草装置１０の前側に設け、この補助分草装置１５を取付けた分草装置１０は、補助分草装置１５を取付けていない分草装置１０と同様に形成することで、部品を共用すると共に、この分草装置１０を走行の目印として従前と同じ感覚で使用できるが、分草装置１０の他に別途補助分草装置１５専用の取付体を分草杆１４の先端に設けてもよい。
また、分草装置１０は前後方向の分草杆分草杆１４の先端に取付け、分草杆１４の基部は刈取部４の固定部に任意部分に固定すればよい。
【００２０】
また、刈取部４は刈刃１２の上方から後側には刈刃１２によって刈り取った穀稈を搬送する株元搬送装置（図示省略）と穂先搬送装置（図示省略）等の穀稈搬送装置４６を設ける。４７は扱深さ調節用搬送装置、４８は脱穀装置３に穀稈を供給する穀稈供給搬送装置４９に穀稈を引き継ぐ引継搬送装置である。
５０は刈取部４の刈取フレーム、５１は刈取フレーム５０を取付けた縦支持フレーム、縦支持フレーム５１の基部は機体フレーム１側に設けた支持台に回転自在に取付け、縦支持フレーム５１には刈取上下シリンダ５２を取付け、刈取上下シリンダ５２を伸縮させて刈取部４を上下回動させる。
【００２１】
しかして、走行装置２により圃場を走行すると、刈取部４の分草装置１０が圃場の穀稈を分草し、分草された穀稈は引起装置１１により引き起こされ、引き起こされた穀稈が刈刃１２により切断され、穀稈搬送装置４６により穀稈供給搬送装置４９に穀稈を搬送し、穀稈供給搬送装置４９により脱穀室に穀稈が供給されて脱穀される。
この刈取脱穀作業は、通常、圃場を左周りに周回して行う回り刈りと、広い圃場の場合は穀稈群の中央を先ず刈取って複数の穀稈群に分断し、この分断するために穀稈群の中央に割り込んで行う刈取作業を中割といい、中割して分断された夫々の穀稈群の周囲を周回して回り刈りを行う。
【００２２】
そして、前記回り刈りするときの最初に行う畦際の穀稈の刈取や中割では、把手兼ストッパ３１を持って上側補助分草体１７を下側補助分草体１６に対して上動させる。
そのため、補助分草装置１５は上端位置が高くなって、目印として作用して、走行方向の見極めを容易にして操作性を向上させ、また、上側補助分草体１７を高くした分穀稈との接触面積を大きくして分草効果を上げる。
また、通常の回り刈りのときは上側補助分草体１７を下げると、把手兼ストッパ３１が下側補助分草体１６の上縁に当接し、上側補助分草体１７の下動を停止させる。そのため、通常の刈取作業のとき上側補助分草体１７を下動させることで、前方視界の障害にならず、作業性を低下させない。
【００２３】
しかして、上側補助分草体１７は、右分草板２８と左分草板２９との前端を一体的に形成し、右分草板２８および左分草板２９の後端は自由端に形成し、この上側補助分草体１７の後端の自由端部を下側補助分草体１６の内面（後面）側の左右両側に設けた摺動溝３０に嵌合させているから、上側補助分草体１７の外面（前面）全体が下側補助分草体１６の内面（後面）に摺接するので、この摺接抵抗によって上側補助分草体１７は下側補助分草体１６に対して上下動が停止する。
この場合、下側補助分草体１６と上側補助分草体１７の間にはロック手段３２を設けているから、上側補助分草体１７に設けた係合孔３５にロック手段３２の係合部材３４を係合させると、上側補助分草体１７は下側補助分草体１６に対して確実に固定される。この場合、係合孔３５を上下に所定の間隔を置いて複数並設すると、所望高さ位置にて上側補助分草体１７を保持できる。
【００２４】
しかして、下側補助分草体１６に対して上下する上側補助分草体１７は、その右分草板２８と左分草板２９を夫々左右に分割して、夫々単独で上下自在に構成すると、一層、圃場や穀稈状態に対応でき、操作性および作業性を向上させる。即ち、畦際の刈取作業のとき、上側補助分草体１７の内の畦側の右分草板２８を下動させることにより、畦と補助分草装置１５の先端との位置関係を容易に視認しつつ、左分草板２９を高く上動させることで、分草効果を期待でき、操作性と作業性とを両立させられる。
