Description

【０００１】
【産業上の利用分野】
本発明は、コンバイン等の刈取部に係るものである。
【０００２】
【従来技術】
従来公知の、特開平５−２９２８２８号公報には、分草作用位置にある分草体を、引起装置の前側上方に移動させる構成について記載されている。
また、特開平７−２５５２４９号公報には、分草作用位置にある分草体を、引起装置の前側上方に平行移動させる構成について記載されている。
また、特開平７−２９８７５４号公報には、分草作用位置にある分草体を、反転用軸中心に反転させる構成について記載されている。
また、特開昭６３−８５０４２号公報には、分草作用位置にある分草体を、反転用軸中心に回動させる構成について記載されている。
【０００３】
【発明が解決しようとする課題】
前記公知例のうち特開平５−２９２８２８号公報に記載されたものは、分草杆を分草体ごと上動させる構成のため、刈取部のフレーム全てを変形させる必要があり、構成が複雑でコストが高くなるという課題がある。
また、特開平７−２５５２４９号公報に記載されたものは、分草作用位置にある分草体を、引起装置の前側上方に平行移動させる構成のため、引起装置の前側部分の上動機構に穀稈が絡むという課題がある。
また、特開平７−２９８７５４号公報に記載されたものは、分草作用位置にある分草体を、反転用軸中心に反転させる構成であるが、反転させて尖った先端部を上方に位置させて路上走行するものであり、畦に引起装置を近づけることはできないという課題がある。
また、特開昭６３−８５０４２号公報に記載されたものは、単に分草作用位置にある分草体を、反転用軸中心に回動させる構成なため、分草体の分草面の位置が左右に変化するだけであり、畦に引起装置を近づけることはできないという課題がある。
即ち、畦付近の穀稈は、前方に突き出る分草体により刈取部が畦に近づけないので、刈取ることができないが、分草体を引起装置の前側所定位置より移動させると、畦に刈取部（引起装置および刈刃）を近づけて刈取ることができる。
そこで、簡単な構成で分草体を移動させて、畦に引起装置を近づけられるようにしたものである。
【０００４】
【発明の目的】
畦付近の穀稈の刈取り作業の実現、分草体の移動機構の簡素化、作業および操作のよう威勢の向上、コストの削減。
【０００５】
【課題を解決するための手段】
本発明は、左右に複数並設した穀稈を分草する分草体１１と、該分草体１１の後方に設けた引起装置１２とを有する刈取部４を備え、前記分草体１１を、少なくとも、反転用軸３４および該反転用軸３４の軸受部材３６と取付用筒３３と横軸３２と反転アーム３０とを有した分草体ユニットＹに備え、縦支持フレーム８の先端に設ける左右方向の下部伝動筒２０に固定した分草杆２１に、前記軸受部材３６を着脱自在に取付け、該軸受部材３６に反転用軸３４を回転のみ自在に挿入し、該反転用軸３４には前後方向の取付用筒３３を挿入固定し、該取付用筒３３には左右方向の横軸３２を固定し、該横軸３２には前記分草体１１を取付けた反転用アーム３０を固定し、前記反転用軸３４は、前記引起装置１２の引起ケース４４を移動する引起ラグ２５の移動方向に対して略直交するように前後方向に設け、前記分草体１１は、反転用軸３４中心に、分草体１１の先端部２２が下方に分草面２３が上方に位置する分草作用位置と、分草面２３が下方に先端部２２が上方であって所定高さに位置する反転位置との間回転自在な構成とし、前記反転位置へ回転させた分草体１１の下部が、前記引起装置１２の引起ケース４４の下部よりも上方に位置する構成とし、前記分草体１１を反転用軸３４中心に回転させる駆動源５４を備えた回転作動手段５１を設け、該回転作動手段５１は、前記分草体１１を反転位置へ回転および分草作用位置へ復帰させると共に、前記分草体１１の先端部２２を、左右の任意の回転位置に停止、あるいは、左右方向に往復移動させつつ機体を前進可能な構成とし、さらに、刈取部４を所定高さ以上に上動させると、該刈取部４を自動的に駆動停止させると共に前記分草体１１を自動的に反転位置へ回転させ、前記刈取部４を所定高さの作業位置に降下させると、該刈取部４を自動的に駆動開始させると共に前記分草体１１を反転位置へ回転させる前の分草作用位置に自動復帰させる構成としたことを特徴とするコンバインとしたものである。
【０００６】
【実施例】
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、５はグレンタンク、６は操縦部である。
前記機体フレーム１側に設けた支持台７には前方に伸びる縦支持フレーム８の基部を回動自在に取付け、縦支持フレーム８には前記刈取部４を設け、縦支持フレーム８を刈取上下シリンダ９により上下回動させて刈取部４を上下動自在に構成する。
【０００７】
刈取部４は、最前方位置に分草体１１を設け、分草体１１の後側に引起装置１２を設け、引起装置１２の後側に掻込装置１３を設け、掻込装置１３の下方に刈刃１４を設け、刈刃１４の後側に切断した穀稈を搬送する搬送装置１５を設けて構成している。１６はスターホイル、１７は搬送装置１５の終端側に設けた扱深さ調節装置、１８は穀稈供給装置１９に引き継ぐ引継搬送装置である。
しかして、前記縦支持フレーム８の先端に左右方向の下部伝動横筒２０を設け、下部伝動横筒２０には左右に所定に間隔を置いて複数の分草杆２１の基部を固定し、各分草杆２１の先端側には分草体１１を夫々設ける。
複数の分草体１１のうち、一部または全部の分草体１１は、上下反転自在に設ける。
【０００８】
即ち、分草体１１は側面視先鋭形状の先端部２２より後方に至るに従い高くなるように傾斜する分草面２３を形成し、分草面２３は上方に至るに従い幅が広くなる正面視三角形状に形成し、この分草体１１を先端部２２が上に分草面２３が下になるように逆さに反転させ、前記引起装置１２および刈刃１４を圃場の畦２４に接近させるように構成する。
したがって、分草体１１の先端部２２から引起装置１２の引起ラグ２５までの距離Ｌより、分草体１１を反転させることにより分草面２３から引起ラグ２５までの距離Ｋが短くなるように構成する。
【０００９】
実施例では、左右何れか一方または両方および中間の分草体１１を上下反転自在に構成している。
分草体１１には、側面視逆Ｌ型形状の反転用アーム３０の先端を固定し、反転用アーム３０の基部には左右方向の横筒３１を固定し、横筒３１は左右方向の横軸３２に嵌合させる。横軸３２は前後方向の取付用筒３３に固定し、取付用筒３３は前後方向の反転用軸３４に挿入固定し、反転用軸３４は軸受部材３６に回転のみ自在に挿入し、軸受部材３６は取付金具３７に固定し、取付金具３７はボルト等の止着具３８により分草杆２１に固定したステー３５に着脱自在に取付ける。
したがって、分草体１１は取付用筒３３を反転用軸３４ごと軸受部材３６に対して回転させることにより反転させている。
【００１０】
この場合、分草体１１は反転用アーム３０の長さを半径にして反転用軸３４を中心に回転するから、反転用アーム３０の長さおよび反転用軸３４の位置を、反転させたとき分草体１１あるいは反転用軸３４に取付ける反転用アーム３０等が畦２４に接触しない高さに位置するように設定する。
また、分草体１１は、任意構成の分草体ユニットＹとして事前に組立て、これを分草杆２１に取付ける。実施例では、反転用アーム３０と、横筒３１と、横軸３２と、取付用筒３３とを小ユニットとして反転用軸３４に着脱自在に構成しているが、反転用軸３４と軸受部材３６と取付金具３７までも分草体ユニットＹとして構成し、ボルト等の止着具３８により分草杆２１に固定したステー３５に着脱自在に取付けている。なお、後述する回転作動手段５１もユニットに含めると、一層組立および着脱を含めてメンテンナンスが容易になって好適である。
【００１１】
しかして、前記分草杆２１は、前記刈刃１４より先側の部分を、少なくとも刈刃１４の部分と略同じ高さに位置させて刈刃１４の前方に空間部４０を形成して穀稈等の詰まりを減少させるが、分草杆２１を前側に至るに従い高くなるように構成すると、空間部４０を大きく（広く）できて、一層穀稈等の詰まりが減少できて好適である。
しかして、分草体１１は前記反転用軸３４中心に回転することにより反転するが、反転用軸３４は正面視作用状態の分草体１１の後方に重合させて位置させ、また、分草体１１の回転方向は前記引起装置１２の引起ケース４４の外側（前記反転用軸３４を基準に反引起ラグ２５側）を回転移動するように構成する。
また、反転用アーム３０は側面視、前記引起装置１２の引起ラグ２５の移動軌跡と重ならないように配置して引起ラグ２５との干渉を防止する。このとき、引起ラグ２５の前側に反転用アーム３０を位置させると、組み付け等が容易になって、好適である。
【００１２】
また、反転用軸３４と軸受部材３６の取付部分は最下方位置にある引起ラグ２５の先端より上方に位置させると、分草体１１を反転用軸３４中心に反転させたとき、引起装置１２の引起ラグ２５の先端より上方に位置し、刈取部４を畦２４に近づけられ、また、引起ラグ２５の作用への干渉を防止して好適である。また、反転させた分草体１１の分草面２３の下部は引起装置１２の引起ケース４４の下部よりも高く位置させ、引起ラグ２５の作用への干渉を防止している（図１２）。また、反転させた分草体１１の最も前側に位置する部分を、最下方位置にある引起ラグ２５の先端より後方に位置させると、刈取部４を畦２４に近づけられ、また、引起ラグ２５の作用への干渉を防止して好適である（図１２）。
また、反転用軸３４中心に反転させた分草体１１は、操縦部６からその分草体１１の先端部２２または分草面２３の何れかの部分が見えるように構成する。この場合、反転させた分草体１１は、引起装置１２の下側に設けた引起ラグ２５を取付けたチエンを掛け回すローラ４６の中心と刈取部４の側部カバー４７の間に位置させると、反転状態のときでも刈取部４の条合せ操作を容易にする。特に、操縦部６の前方となる側の分草体１１を前記のように配置すると、一層、条合せが容易になって好適である。
【００１３】
しかして、分草体１１は、反転させて引起装置１２および刈刃１４を畦２４に近づけられるようにするので、分草体１１を反転させたとき、元の位置より後方に位置するように前記取付用筒３３を設ける。即ち、反転用軸３４は前記引起装置１２の引起ケース４４に対して側面視略直交するように配置して、後側に斜めに倒れた状態に設けられている引起ケース４４に対して干渉せずに分草体１１を反転させられ、引起装置１２および刈刃１４を畦２４に近づけられる。
しかして、分草体１１は、大型分草体１１a と小型分草体１１b を左右方向に交互に配置しているが、このうち、大型分草体１１a を反転させるようにして、刈取部４を畦２４に接近させる距離を稼いでいる。
即ち、全ての分草体１１を反転させても良いが、構造が複雑になって、コストが上昇するので、畦２４付近の刈取りに有効な大型分草体１１a を反転させる。
【００１４】
しかして、大型分草体１１a のうち、左右の中間位置にある中間分草体１１も反転するように構成すると、刈取部４全体を前進させて畦２４に近づくことができて、好適である（図１３、図１４）。
中間分草体１１は、左右の引起装置１２の引起ケース４４の間に中間分草杆２１を位置させ、該中間分草杆２１の上方にステー３５を設け、該ステー３５に軸受部材３６を固定し、軸受部材３６に反転用軸３４を回転のみ自在に挿入し、軸受部材３６より前側に突出する反転用軸３４に取付用筒３３を挿入固定して取付け、取付用筒３３には下向きの一対のステーを固定し、該ステーに横軸３２により横筒３１を設け、横筒３１に反転用アーム３０の基部を固定する。
また、引起装置１２の引起ケース４４の下部は、前記分草杆２１の先側に設けた引起ケース取付部材４５に取付け（図２）、各分草杆２１と引起ケース４４とは互いに強度メンバーとなるフレームを構成して、分草体１１に掛かる荷重を支持している。
【００１５】
しかして、前記反転用軸３４の後端は前記軸受部材３６の後端より後方に突出させ、反転用軸３４の後端には回転作動手段５１を設け、回転作動手段５１により分草体１１は取付用筒３３中心に回転して反転する。
実施例では、回転作動手段５１は、前記反転用軸３４の後端に入力ギヤ５２を固定し、入力ギヤ５２に出力ギヤ５３を噛み合わせ、出力ギヤ５３はモータあるいは空気・油圧等の流体により作動する流体シリンダ等の駆動源５４により回転させて分草体１１を反転および復帰させる（図３、図４、図１４）。
しかして、分草体１１は、図１６のように、左回りの回り刈りするときは右側の分草体１１を反転させると、有効であり、また、畦２４際の刈取りでも反転させる（図１７）。
また、図１８のように、反転用軸３４中心に分草体１１を回動させると、先端部２２を左右に移動させることができ、これにより、分草体１１の位置を左右移動させたのと同等の作用を奏する。即ち、先端部２２を内側にすると、条刈のとき既刈地側にある切り藁または放出藁を分草体１１が押していくのを防止し、また、先端部２２を外側にすると、中割の刈取のとき刈取部４の刈り幅を広くして条刈より１条多く確実に刈取り穀稈を分草作用幅内に入れられる。
【００１６】
また、先端部２２を左右に首を振るように往復移動させながら前進しても良い。６１はＣＰＵ、６２は倒伏モード検出スイッチ、６３は刈取スイッチである。
しかして、分草体１１を前記駆動源５４により反転および復帰等の反転用軸３４中心に回転させる場合は、前記駆動源５４の操作部６０をコンバインの操縦部６に設けると、遠隔操作が可能になって、操作性を向上させて好適である。
この場合、刈取部４の上下に合わせて自動反転させると、分草体１１の上面に載っている異物を除去でき、操作性および作業性を向上させる、即ち、刈取部４を所定高さ以上に上動させとき、自動反転させ、刈取部４を所定高さの作業位置に降下させると、自動復帰させる。
また、コンバインを旋回操作したとき、刈取部４の駆動の入り切りを自動的に行うように制御するように構成している場合は、この刈取部４の駆動の入り切りに対応させて、刈取部４の駆動を切るとき反転させて、入れるときに自動復帰するように構成してもよい。
【００１７】
次に作用を述べる。
走行装置２により圃場を走行すると、刈取部４の分草体１１が圃場の穀稈を分草し、分草された穀稈は根元が刈刃１５により切断され、掻込装置１３により掻き込まれ、搬送装置１５により搬送され、引継搬送装置１８により穀稈を穀稈供給装置１９に引継ぎ、穀稈供給装置１９により脱穀装置３に供給して脱穀される。
この場合、分草体１１は、前後方向の反転用軸３４中心に、先端部２２が先端に位置する作用位置と、先端部２２が上方に位置する反転位置との間移動自在に構成しているから、通常は先端部２２を先端に位置させた作用位置として圃場の穀稈を分草し、所定の場合反転させる。
分草体１１は、側面視先端部２２より後側に後方に至るに従い高くなるように傾斜する分草面２３を形成し、分草面２３は上方に至るに従い幅が広くなる正面視三角形状に形成しているから、この分草体１１を先端部２２が上に分草面２３が下になるように逆さに反転させると、分草面２３から引起ラグ２５までの距離Ｋが短くなって、引起装置１２および刈刃１４を畦２４に近づける。
【００１８】
また、畦２４近傍の刈取り時、雑草が引っ掛かるときがあるが、反転させることによりこれを防げる。
また、反転させることにより分草体１１の上面に載っている異物を落下させられる。
以上のように、複数ある分草体１１のうち旋回外側の分草体１１を反転させると回り刈りのときに良く、各分草体１１の全部を反転させると、刈取部４を畦２４に向けて直進状態で前進させる場合は、刈取部４全体を畦２４に近づけることができ、畦２４際の穀稈の刈取りを行える。
しかして、分草体１１は、反転用軸３４中心に反転させたとき、操縦部６から分草体１１の先端部２２または分草面２３の何れかの部分が見えるようにしているから、反転状態のときでも、分草体１１を見ながら刈取部４の条合せ操作可能になって、操作を容易にする。
【００１９】
また、分草体１１は反転させたとき、引起装置１２の下側に設けたローラ４６の中心と刈取部４の側部カバー４７の間に位置させると、反転状態のときでも刈取部４の条合せ操作を容易にする。特に、操縦部６の前方となる側の分草体１１を前記のように配置すると、一層、条合せが容易になって好適である。
しかして、分草体１１は、大型分草体１１a と小型分草体１１b を左右方向に交互に配置しているが、このうち、前方に大きく突出している大型分草体１１a を反転させると、刈取部４を畦２４に接近させる距離を稼げる。
即ち、全ての分草体１１を反転させても良いが、構造が複雑になって、コストが上昇するので、畦２４付近の刈取りに有効な大型分草体１１a を反転させることにより、合理的な構成となる。また、全長を短くでき、トラックに積載するのや収納を容易にする。
【００２０】
しかして、分草体１１は、反転用アーム３０の先端に固定し、反転用アーム３０の基部は横筒３１に固定し、横筒３１は横軸３２に嵌合させ、横軸３２は取付用筒３３に固定し、取付用筒３３は分草杆２１側に設けた前後方向の反転用軸３４に着脱自在に挿入しているから、分草体１１と反転用アーム３０と横筒３１と横軸３２と取付用筒３３を一体的に反転用軸３４に対して回転させると、反転させることができる。
実施例では、前記反転用軸３４の後端は分草杆２１側に固定の軸受部材３６の後端より後方に突出させ、反転用軸３４の後端には回転作動手段５１を設けているから、回転作動手段５１により分草体１１は取付用筒３３中心に回転して反転する。
【００２１】
また、前記反転用軸３４の後端に入力ギヤ５２を固定し、入力ギヤ５２に駆動源５４の出力ギヤ５３を噛み合わせているから、駆動源５４に通電すると、反転用軸３４を回転させて分草体１１を反転させる。
しかして、分草体１１の反転中心の反転用軸３４は、正面視作用状態の分草体１１の後方に重合させて位置させているから、支持機構および反転機構等を分草体１１の後方に位置させことができ、穀稈が接触・絡むのを防止する。
また、分草体１１の回転方向は前記引起装置１２の引起ケース４４の外側（前記反転用軸３４を基準に反引起ラグ２５側）を回転移動するように構成しているから、引起装置１２が穀稈を引起しているときも、分草体１１は引起装置１２の引起ラグ２５の移動路に干渉せずに反転させられ、穀稈を引っかけず、穀稈の搬送姿勢を乱したり、穂を脱粒させるのを防止する。また、右側の引起装置１２の外側に分草体１１が位置するので、刈取り穀稈を見るのに視界を遮らず、前方視界を良好にする。
【００２２】
また、反転用アーム３０は側面視、前記引起装置１２の引起ラグ２５の移動軌跡と重ならないように配置しているから、分草体１１が分草作業状態のとき、引起ラグ２５に反転用アーム３０が干渉するのを防止する。
このとき、引起ラグ２５の移動路に対して反転用アーム３０は前後に配置可能であるが、側面視前側に反転用アーム３０を位置させると、組み付け等が容易になって、好適である。
しかして、反転用軸３４は引起装置１２の引起ケース４４に対して略直交するように配置しているから、分草体１１を反転させたとき、最も元の位置から後側に遠く離すことができ、引起装置１２および刈刃１４を畦２４に近づけられる。
【００２３】
また、反転させた分草体１１の前側に位置する部分が引起装置１２の引起ラグ２５の先端より後方に位置するように反転用軸３４を配置しているから、刈取部４を畦２４に近づけられて好適である。
同様に、分草体１１を反転用軸３４中心に反転させたとき、取付用筒３３と軸受部材３６の取付部分が引起装置１２の引起ラグ２５の先端より上方に位置するように構成しているから、引起ラグ２５の作用への干渉を防止して好適である。
同様に、分草体１１を反転用軸３４中心に反転させたとき、反転させた状態の分草体１１の分草面２３下部が引起装置１２の引起ケース４４の下部よりも上方に位置するように構成しているから、引起装置１２および刈刃１４を畦２４に近づけられる。
【００２４】
しかして、大型分草体１１a のうち、左右の中間位置にある中間分草体１１も反転するように構成しているから、刈取部４全体を前進させて畦２４に近づくことができる。
この場合、中間分草体１１は、左右の引起装置１２の引起ケース４４の間に中間分草杆２１を位置させ、該中間分草杆２１の上方にステー３５を設け、該ステー３５に軸受部材３６を固定し、軸受部材３６に反転用軸３４を回転のみ自在に挿入し、軸受部材３６より前側に突出する反転用軸３４に中間分草体１１の取付用筒３３を挿入固定して取付けているから、反転させた中間分草体１１は左右の引起ケース４４の間に位置し、中間の分草体１１でも左右を移動する穀稈に干渉するのを防止する。
しかして、分草体１１は、図１６のように、左回りの回り刈りするときは右側の分草体１１を反転させるから、畦２４に対して実質的な旋回半径を小にして畦２４に近づける。
【００２５】
また、図１８のように、反転用軸３４中心に分草体１１を回動させると、先端部２２を左右に移動させることができるから、先端部２２を内側にすると、刈取部４の刈り幅を狭くし、先端部２２を外側にすると、刈取部４の刈り幅を広くし、分草体１１の位置を左右移動させたのと同等の作用を奏する。特に、条刈のときは先端部２２を内側にすると、既刈地側にある切り藁または放出藁を分草体１１が押していくのを防止し、また、中割の刈取のときは先端部２２を外側にすると、刈取部４の刈り幅を広くして確実に刈取り穀稈を分草作用幅内に入れられる（中割のときは条刈より１条多く刈取れることになる）。
また、分草体１１は先端部２２を左右に首を振るように往復移動させながら前進させることも可能であるから、倒伏穀稈の刈取作業のとき、振動状態に往復移動する先端部２２が倒伏穀稈の下側に進入しやすく、分草および穀稈を起こす作用が良好となる。
【００２６】
しかして、分草体１１の反転復帰操作は、駆動源５４を操作する操作部６０をコンバインの操縦部６に設けると、遠隔操作が可能になって、操作性を向上させて好適である。
この場合、刈取部４の上下に合わせて自動反転させるように構成すると、分草体１１の上面に載っている異物を除去でき、操作性および作業性を向上させる。
即ち、刈取部４を所定高さ以上に上動させとき、自動反転させ、刈取部４を所定高さの作業位置に降下させると、自動復帰させるように構成すると、著しく操作性および作業性を向上させる。
【００２７】
また、コンバインの旋回操作に関連して、刈取部４の駆動の入り切りを自動的に行うように制御するように構成している場合は、この刈取部４の駆動の入り切りに対応させて、刈取部４の駆動を切るとき反転させて、入れるときに自動復帰するように構成すると、刈取部４を所定高さ以上に上動させると、自動的に駆動を停止させて分草体１１を反転させ、刈取部４を所定高さ以下に下動させると、自動的に駆動させて分草体１１を復帰させ、操作性および作業性を向上させ、また、ソフトの変更ですむので、コストも上昇させない。
しかして、分草体１１は分草杆２１の先側に設けられているが、分草杆２１は、刈刃１４より先側の部分を、少なくとも刈刃１４と略同じ高さに位置させて、刈刃１４の前方に空間部４０を形成しているから、分草杆２１の下方に穀稈屑等が詰まるのを減少させる。
【００２８】
また、分草杆２１は前側に至るに従い高くなるように構成すると、空間部４０を大きく（広く）できて、一層穀稈等の詰まりが減少できて好適である。
しかして、分草体１１は任意構成の分草体ユニットＹとして事前に組立て、これを分草杆２１に取付けるから、組立ておよび着脱を容易にし、メンテナンスも容易にする。
実施例では、反転用アーム３０と、横筒３１と、横軸３２と、取付用筒３３とを小ユニットとして反転用軸３４に着脱自在に取付けて構成しているから、この場合は、取付用筒３３を反転用軸３４に着脱すればよい。即ち、最も破損しやすい分草体１１と反転用アーム３０を小ユニットとして反転用軸３４に着脱自在に取付けているから、最小限の部品交換ですみ、作業が容易になる。
【００２９】
また、反転用アーム３０と、横筒３１と、横軸３２と、取付用筒３３と、反転用軸３４と軸受部材３６と取付金具３７とを分草体ユニットＹとして構成すると、ボルト等の止着具３８により分草杆２１に固定したステー３５に着脱自在に取付ければよく、最初の組立てが容易になり、また、着脱が容易になって、分草体１１付近のメンテナンスが容易になり好適である。
前記分草体ユニットＹ（モータ５４等の回転作動手段５１を含む）を取付ける分草杆２１は、基部を左右方向の下部伝動横筒２０側に固定し、その先端側に設けた引起ケース取付部材４５を引起ケース４４の下部に固定しているから、下部伝動横筒２０と各分草杆２１と引起ケース４４とは互いに強度メンバーとなるフレームを構成して、分草体１１に掛かる荷重を支持する。
【００３０】

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a machine frame, 2 denotes a traveling device provided at a lower position of the machine frame 1, 3 denotes a threshing device provided at an upper position of the machine frame 1, and 4 denotes a threshing device 3. A cutting part provided on the front side of the slab, 5 is a glen tank, and 6 is a control part.
A base portion of a vertical support frame 8 extending forward is rotatably attached to a support base 7 provided on the machine body frame 1 side, and the cutting support 4 is provided on the vertical support frame 8, and the vertical support frame 8 is a cutting upper and lower cylinder. The cutting part 4 is configured to be movable up and down by rotating up and down by 9.
[0007]
The cutting unit 4 is provided with the weeding body 11 at the foremost position, the pulling device 12 is provided on the rear side of the weeding body 11, the scraping device 13 is provided on the rear side of the pulling device 12, and the cutting unit 13 is cut below the scoring device 13. A blade 14 is provided, and a conveying device 15 for conveying the cut cereal is provided on the rear side of the cutting blade 14. 16 is a star wheel, 17 is a handling depth adjusting device provided on the terminal end side of the conveying device 15, and 18 is a takeover conveying device that takes over to the grain supply device 19.
Thus, the lower transmission horizontal cylinder 20 is provided at the front end of the vertical support frame 8, and the bases of the plurality of weed tubs 21 are fixed to the lower transmission horizontal cylinder 20 at predetermined intervals on the left and right sides. A weed body 11 is provided on the tip side of the weed pod 21.
Among the plurality of weed bodies 11, some or all of the weed bodies 11 are provided so as to be upside down.
[0008]
That is, the weeding body 11 forms a weeding surface 23 that inclines so as to become higher from the front end portion 22 having a sharp side view, and the weeding surface 23 has a triangular shape in front view that becomes wider as it goes upward. The weed body 11 is inverted upside down so that the tip 22 is on the top and the weed surface 23 is on the bottom, and the pulling device 12 and the cutting blade 14 are made to approach the basket 24 in the field. .
Therefore, the distance K from the weed surface 23 to the raising lug 25 is shortened by reversing the weeding body 11 from the distance L from the tip 22 of the weeding body 11 to the raising lug 25 of the raising device 12. .
[0009]
In the embodiment, either one or both of the left and right sides and the intermediate weed body 11 are configured to be vertically inverted.
A tip of a reversing arm 30 having an inverted L shape when viewed from the side is fixed to the weed body 11, and a horizontal cylinder 31 in the left-right direction is fixed to the base of the reversing arm 30, and the horizontal cylinder 31 is a horizontal axis in the left-right direction. 32. The horizontal shaft 32 is fixed to the mounting cylinder 33 in the front-rear direction, the mounting cylinder 33 is inserted and fixed to the reversing shaft 34 in the front-rear direction, and the reversing shaft 34 is inserted into the bearing member 36 so as to be rotatable only. 36 is fixed to a mounting bracket 37, and the mounting bracket 37 is detachably mounted on a stay 35 fixed to the weed tub 21 by a fastening member 38 such as a bolt.
Therefore, the weeding body 11 is reversed by rotating the mounting cylinder 33 with respect to the bearing member 36 together with the reversing shaft 34.
[0010]
In this case, since the weeding body 11 rotates around the reversing shaft 34 with the length of the reversing arm 30 as the radius, the length of the reversing arm 30 and the position of the reversing shaft 34 are changed when the reversing arm 30 is reversed. The reversing arm 30 or the like attached to the grass body 11 or the reversing shaft 34 is set so as to be at a height where it does not come into contact with the rod 24.
Moreover, the weeding body 11 is assembled in advance as an arbitrarily configured weeding body unit Y, and this is attached to the weeding basket 21. In the embodiment, the reversing arm 30, the horizontal cylinder 31, the horizontal shaft 32, and the mounting cylinder 33 are detachably attached to the reversing shaft 34 as small units. 36 and the mounting bracket 37 are also configured as a weeding body unit Y, and are detachably attached to a stay 35 fixed to the weeding tub 21 with a fastening member 38 such as a bolt. In addition, it is preferable that the rotation actuating means 51, which will be described later, is also included in the unit because maintenance is facilitated including further assembly and detachment.
[0011]
Thus, the weed ridge 21 has a space 40 formed in front of the cutting blade 14 with a portion on the front side of the cutting blade 14 positioned at least at the same height as the cutting blade 14 portion. Although clogging such as cocoons is reduced, it is preferable to make the weed cocoon 21 higher as it reaches the front side, because the space 40 can be made larger (wider), and clogging of cereals and the like can be further reduced.
Thus, the weed body 11 is reversed by rotating around the reversing shaft 34, but the reversing shaft 34 is superposed and positioned behind the weed body 11 in the front view action state. The rotation direction is configured to rotate and move outside the pulling case 44 of the pulling device 12 (on the counter pulling lug 25 side with respect to the reversing shaft 34).
Further, the reversing arm 30 is disposed so as not to overlap the movement locus of the pulling lug 25 of the pulling device 12 in a side view, thereby preventing interference with the pulling lug 25. At this time, if the reversing arm 30 is positioned on the front side of the pull-up lug 25, it is preferable because assembly becomes easy.
[0012]
Further, when the reversing shaft 34 and the mounting portion of the bearing member 36 are positioned above the tip of the pulling lug 25 at the lowest position, when the weed body 11 is reversed around the reversing shaft 34, It is located above the front end of the pulling lug 25, and the cutting part 4 can be brought close to the rod 24, and interference with the action of the pulling lug 25 is prevented. Further, the lower portion of the weed surface 23 of the inverted weed body 11 is positioned higher than the lower portion of the pulling case 44 of the pulling device 12 to prevent interference with the action of the pulling lug 25 (FIG. 12). Moreover, when the part located in the foremost side of the inverted weed body 11 is positioned behind the leading end of the pulling lug 25 in the lowermost position, the cutting part 4 can be brought close to the rod 24, and the pulling lug 25 It is preferable to prevent interference with the action (FIG. 12).
Further, the weed body 11 that is inverted about the center of the reversing shaft 34 is configured so that either the front end portion 22 or the weed surface 23 of the weed body 11 can be seen from the control unit 6. In this case, when the inverted weed body 11 is positioned between the center of the roller 46 around which the chain attached with the pulling lug 25 provided on the lower side of the pulling device 12 and the side cover 47 of the cutting unit 4 is placed, Even in the inverted state, the alignment operation of the cutting unit 4 is facilitated. In particular, it is preferable to arrange the weeding body 11 on the front side of the control unit 6 as described above because the alignment becomes easier.
[0013]
Thus, since the weed body 11 is inverted so that the pulling device 12 and the cutting blade 14 can be brought close to the rod 24, when the weed body 11 is inverted, the attachment is performed so that it is located behind the original position. A cylinder 33 is provided. That is, the reversing shaft 34 is disposed so as to be substantially orthogonal to the pulling case 44 of the pulling device 12 in a side view, and interferes with the pulling case 44 that is provided in a state of being inclined obliquely to the rear side. Instead, the weeding body 11 is inverted, and the pulling device 12 and the cutting blade 14 can be brought closer to the rod 24.
Thus, in the weeding body 11, the large weeding body 11a and the small weeding body 11b are alternately arranged in the left-right direction. Earn a distance to approach.
That is, all the herbaceous bodies 11 may be inverted, but the structure becomes complicated and the cost increases. Therefore, the large herbicidal body 11a effective for cutting near the reed 24 is inverted.
[0014]
Therefore, it is preferable that the intermediate weed body 11 at the left and right intermediate positions of the large weed body 11a is reversed so that the whole cutting unit 4 can be moved forward and approach the reed 24. 13, FIG. 14).
In the intermediate weed body 11, the intermediate weed tub 21 is positioned between the raising cases 44 of the left and right pulling devices 12, a stay 35 is provided above the intermediate weed shed 21, and a bearing member 36 is fixed to the stay 35. Then, the reversing shaft 34 is inserted into the bearing member 36 so as to be freely rotatable, and the mounting cylinder 33 is inserted and fixed to the reversing shaft 34 protruding forward from the bearing member 36. A pair of stays are fixed, a horizontal cylinder 31 is provided on the stay by a horizontal shaft 32, and a base portion of the reversing arm 30 is fixed to the horizontal cylinder 31.
Further, the lower part of the pulling case 44 of the pulling device 12 is attached to a pulling case mounting member 45 provided on the front side of the split weed 21 (FIG. 2), and each split weed 21 and the pulling case 44 are strength members. The frame which becomes becomes, and supports the load applied to the weeding body 11.
[0015]
Accordingly, the rear end of the reversing shaft 34 protrudes rearward from the rear end of the bearing member 36, and the rotation operating means 51 is provided at the rear end of the reversing shaft 34. Rotates about the mounting cylinder 33 and reverses.
In the embodiment, the rotation actuating means 51 fixes the input gear 52 to the rear end of the reversing shaft 34 and meshes the output gear 53 with the input gear 52. The output gear 53 is driven by a motor or a fluid such as air or hydraulic pressure. The herbicidal body 11 is reversed and returned by being rotated by a driving source 54 such as an operating fluid cylinder (FIGS. 3, 4, and 14).
Thus, as shown in FIG. 16, when the weed body 11 is turned counterclockwise as shown in FIG. 16, it is effective to invert the right side weed body 11, and is also reversed by cutting at the end of the reed 24 (FIG. 17). .
Also, as shown in FIG. 18, when the weed body 11 is rotated about the reversing shaft 34, the tip 22 can be moved to the left and right, thereby moving the position of the weed body 11 to the left and right. Equivalent effect. That is, when the tip portion 22 is set to the inside, the cutting body 11 is prevented from pushing the cutting hoe or the discharge hoe on the already-cut territory during row cutting, and when the tip portion 22 is set to the outside, the middle portion is divided. At the time of cutting, the cutting width of the cutting unit 4 is widened, and the cutting cereal meal can be surely put into the weeding action width more than the cutting.
[0016]
Moreover, you may move forward, reciprocating the front-end | tip part 22 so that a neck may be shaken to right and left. 61 is a CPU, 62 is a lodging mode detection switch, and 63 is a cutting switch.
Thus, when the herbicidal body 11 is rotated about the reversal shaft 34 for reversal and return by the drive source 54, the operation unit 60 of the drive source 54 is provided in the combine control unit 6 to enable remote operation. Therefore, the operability is improved, which is preferable.
In this case, if it is automatically reversed according to the top and bottom of the cutting unit 4, the foreign matter placed on the upper surface of the weeding body 11 can be removed, and the operability and workability are improved. When it is moved upward, it is automatically reversed, and when the cutting unit 4 is lowered to the working position of a predetermined height, it is automatically returned.
Further, when the harvesting unit 4 is controlled to turn on and off automatically when the combine is turned, the cutting unit 4 is made corresponding to the driving on and off of the cutting unit 4. It may be configured to be reversed when the drive is turned off and to automatically return when the drive is turned on.
[0017]
Next, the operation will be described.
When the traveling device 2 travels through the field, the weeds 11 of the cutting unit 4 weed the cereals in the field, and the roots of the sown cereals are cut by the cutting blades 15 and are scraped by the scraping device 13. The cereals are transported by the transport device 15, the cereals are handed over to the cereal supply device 19 by the takeover transport device 18, and are threshed by being supplied to the threshing device 3 by the cereal supply device 19.
In this case, the weeding body 11 is configured to be movable between a working position where the tip 22 is located at the tip and a turning position where the tip 22 is located above the center of the reversing shaft 34 in the front-rear direction. Therefore, usually, the cereals in the field are weeded as an action position where the tip 22 is located at the tip, and reversed in a predetermined case.
The weeding body 11 forms a weeding surface 23 that inclines so as to increase rearward from the front end portion 22 in side view, and the weeding surface 23 has a triangular shape in front view that increases in width as it extends upward. Therefore, if the weed body 11 is inverted upside down so that the tip portion 22 is on the top and the weed surface 23 is on the bottom, the distance K from the weed surface 23 to the pulling lug 25 is shortened, The pulling device 12 and the cutting blade 14 are brought close to the reed 24.
[0018]
In addition, weeds may be caught when cutting the vicinity of the reed 24, but this can be prevented by reversing.
Moreover, the foreign material on the upper surface of the weeding body 11 can be dropped by reversing.
As described above, if the weeding body 11 outside the turning of the plurality of weeding bodies 11 is reversed, it is good at the time of turning and cutting, and if all of the weeding bodies 11 are reversed, the cutting unit 4 goes straight toward the ridge 24. When advancing in the state, the whole cutting part 4 can be brought close to the cocoon 24, and the grain cocoon at the heel 24 can be reaped.
Thus, when the weed body 11 is reversed to the center of the reversing shaft 34, the tip portion 22 or the weed surface 23 of the weed body 11 can be seen from the control unit 6 so that it is in the inverted state. Even at this time, it becomes possible to perform the alignment operation of the cutting unit 4 while looking at the weed body 11, thereby facilitating the operation.
[0019]
Further, when the weed body 11 is inverted, it is positioned between the center of the roller 46 provided on the lower side of the pulling device 12 and the side cover 47 of the cutting unit 4, so that the strip of the cutting unit 4 is in the inverted state. Facilitates the alignment operation. In particular, it is preferable to arrange the weeding body 11 on the front side of the control unit 6 as described above because the alignment becomes easier.
Thus, in the weeding body 11, the large weeding body 11a and the small weeding body 11b are alternately arranged in the left-right direction. Of these, when the large weeding body 11a protruding greatly forward is reversed, the cutting part 4 Earn enough distance to get closer to 畦 24.
That is, although all the herbaceous bodies 11 may be inverted, the structure becomes complicated and the cost increases. Therefore, a rational configuration can be obtained by inverting the large herbicidal body 11a effective for cutting near the reed 24. It becomes. Also, the overall length can be shortened, making it easy to load and store on a truck.
[0020]
Thus, the weed body 11 is fixed to the tip of the reversing arm 30, the base of the reversing arm 30 is fixed to the horizontal cylinder 31, the horizontal cylinder 31 is fitted to the horizontal axis 32, and the horizontal axis 32 is for mounting. Since it is fixed to the tube 33 and the mounting tube 33 is detachably inserted in the reversing shaft 34 provided in the front-rear direction provided on the weed tub 21 side, the weeding body 11, the reversing arm 30, the horizontal tube 31 and the horizontal When the shaft 32 and the mounting cylinder 33 are integrally rotated with respect to the reversing shaft 34, they can be reversed.
In the embodiment, the rear end of the reversing shaft 34 protrudes rearward from the rear end of the bearing member 36 fixed to the weed ridge 21 side, and a rotation actuating means 51 is provided at the rear end of the reversing shaft 34. Therefore, the weeding body 11 is rotated about the mounting cylinder 33 by the rotation actuating means 51 and reversed.
[0021]
Further, since the input gear 52 is fixed to the rear end of the reversing shaft 34 and the output gear 53 of the driving source 54 is meshed with the input gear 52, when the driving source 54 is energized, the reversing shaft 34 is rotated. Invert the herbaceous body 11.
Accordingly, the reversing shaft 34 at the center of reversal of the weed body 11 is positioned behind the weed body 11 in the front view operation state, so that the support mechanism, the reversing mechanism, and the like are located behind the weed body 11. And prevents the cereals from touching and tangling.
Further, the weeding body 11 is configured so that the rotating direction of the weeding body 11 is rotated on the outside of the pulling case 44 of the pulling device 12 (on the side of the counter pulling lug 25 with respect to the reversing shaft 34). Even when raising the cereal, the weeding body 11 is reversed without interfering with the movement path of the raising lug 25 of the elevating device 12, and does not catch the cereal, disturbing the conveying posture of the cereal, To prevent threshing. Moreover, since the weeding body 11 is located outside the pulling device 12 on the right side, the field of view is not obstructed when viewing the harvested cereal meal, and the front field of view is improved.
[0022]
Further, since the reversing arm 30 is disposed so as not to overlap with the movement locus of the pulling lug 25 of the pulling device 12 in a side view, when the weeding body 11 is in the weeding work state, the reversing arm is placed on the pulling lug 25. 30 prevents interference.
At this time, the reversing arm 30 can be arranged in the front-rear direction with respect to the moving path of the pulling lug 25. However, if the reversing arm 30 is positioned on the front side as viewed from the side, it is easy to assemble and the like.
Therefore, since the reversing shaft 34 is arranged so as to be substantially orthogonal to the pulling case 44 of the pulling device 12, when the weeding body 11 is reversed, it can be separated farthest from the original position to the rear side. The pulling device 12 and the cutting blade 14 can be brought close to the ridge 24.
[0023]
In addition, since the reversing shaft 34 is disposed so that the portion located on the front side of the reversed weed body 11 is located behind the tip of the pulling lug 25 of the pulling device 12, the cutting unit 4 is brought close to the reed 24. Is preferred.
Similarly, when the weed body 11 is inverted about the reversing shaft 34, the mounting portion of the mounting cylinder 33 and the bearing member 36 is configured to be positioned above the tip of the pulling lug 25 of the pulling device 12. Therefore, it is preferable to prevent interference with the action of the pulling lug 25.
Similarly, when the weed body 11 is inverted about the reversing shaft 34, the lower portion of the weed surface 23 of the inverted weed body 11 is positioned above the lower portion of the raising case 44 of the pulling device 12. Since it comprises, the pulling apparatus 12 and the cutting blade 14 can be closely approached to the reed 24.
[0024]
Thus, since the large herbaceous body 11a is also configured to invert the intermediate herbicidal body 11 located at the left and right intermediate positions, the entire cutting unit 4 can be advanced to approach the reed 24.
In this case, in the intermediate weed body 11, the intermediate weed cage 21 is positioned between the raising cases 44 of the left and right elevating devices 12, a stay 35 is provided above the intermediate weed cage 21, and a bearing member is provided on the stay 35. 36, the reversing shaft 34 is inserted into the bearing member 36 so as to be freely rotatable, and the mounting tube 33 of the intermediate weed body 11 is inserted and fixed to the reversing shaft 34 protruding forward from the bearing member 36. Therefore, the inverted intermediate weed body 11 is located between the left and right pulling cases 44, and even the intermediate weed body 11 is prevented from interfering with the cereals that move left and right.
Thus, as shown in FIG. 16, when the weeding body 11 is turned counterclockwise, the right weeding body 11 is inverted, so that the substantial turning radius with respect to the reed 24 is reduced and brought closer to the reed 24. .
[0025]
Further, as shown in FIG. 18, when the weed body 11 is rotated about the reversing shaft 34, the tip 22 can be moved left and right. If the tip 22 is made narrower and the tip 22 is made outward, the cutting width of the cutting part 4 is increased, and the same effect as moving the position of the herbaceous body 11 left and right is obtained. In particular, when the tip 22 is inward at the time of cutting, the cutting body 11 is prevented from pushing the cutting shears or the discharge shear on the already-cut ground side, and at the middle cutting, the tip 22 When the is set to the outside, the cutting width of the cutting part 4 is widened to ensure that the harvested cereal buds are within the weeding action width (at the middle rate, one more line can be cut from the cutting).
Further, since the weed body 11 can be moved forward while reciprocating the tip portion 22 so as to swing the head to the left and right, the tip portion 22 that reciprocates in a vibrating state is fallen down during the harvesting operation of the fallen cereal. It is easy to enter the lower side of the cereal and the action of causing weeds and cereals is improved.
[0026]
Therefore, the reverse operation of the herbicidal body 11 is preferable if the operation unit 60 for operating the drive source 54 is provided in the control unit 6 of the combine to enable remote operation and improve operability.
In this case, if it is configured to be automatically reversed according to the top and bottom of the cutting unit 4, the foreign matter placed on the upper surface of the weeding body 11 can be removed, and operability and workability are improved.
That is, when the mowing unit 4 is moved up to a predetermined height or more, it is automatically reversed, and when the mowing unit 4 is lowered to the working position at the predetermined height, it is automatically restored, so that operability and workability are remarkably improved. Improve.
[0027]
Further, in the case where the control is performed so as to automatically turn on / off the cutting unit 4 in relation to the turning operation of the combine, the cutting is performed in correspondence with the driving on / off of the cutting unit 4. If it is configured to reverse when the drive of the portion 4 is cut off and automatically return when the drive is turned on, when the mowing unit 4 is moved up to a predetermined height or higher, the drive is automatically stopped and the herbaceous body 11 is turned over. When the mowing unit 4 is lowered below a predetermined height, it is automatically driven to restore the weeding body 11, improving operability and workability, and changing the software does not increase the cost. .
Thus, the weed body 11 is provided on the front side of the weed sword 21, but the weed sword 21 has a portion on the front side of the cutting blade 14 at least at the same height as the cutting blade 14. Since the space portion 40 is formed in front of the cutting blade 14, it is possible to reduce clogging of grain swarf and the like below the weed culm 21.
[0028]
In addition, it is preferable that the weed cocoon 21 is configured to become higher as it reaches the front side, because the space 40 can be enlarged (widened), and clogging of cereals and the like can be further reduced.
Thus, since the weed body 11 is assembled in advance as an arbitrarily configured weed body unit Y and attached to the weed tub 21, assembly and detachment are facilitated, and maintenance is also facilitated.
In the embodiment, the reversing arm 30, the horizontal cylinder 31, the horizontal shaft 32, and the mounting cylinder 33 are detachably attached to the reversing shaft 34 as small units. The cylinder 33 may be attached to and detached from the reversing shaft 34. That is, since the weed body 11 and the reversing arm 30 that are most easily damaged are detachably attached to the reversing shaft 34 as a small unit, the work can be facilitated with a minimum of parts replacement.
[0029]
Further, when the reversing arm 30, the horizontal cylinder 31, the horizontal shaft 32, the mounting cylinder 33, the reversing shaft 34, the bearing member 36, and the mounting bracket 37 are configured as the weeding body unit Y, a bolt or the like can be stopped. It is only necessary to detachably attach to the stay 35 fixed to the weed tub 21 by the dressing device 38, which facilitates the initial assembly, facilitates the detachment, and facilitates the maintenance in the vicinity of the weeding body 11. It is.
The weed ridge 21 to which the weed body unit Y (including the rotation actuating means 51 such as the motor 54) is attached has a base fixed to the lower transmission horizontal cylinder 20 side in the left-right direction, and a pulling case mounting member provided on the tip side thereof 45 is fixed to the lower portion of the pulling case 44, so that the lower transmission horizontal cylinder 20, each weed ridge 21 and the pulling case 44 constitute a frame that is a strength member, and supports the load applied to the weeding body 11. To do.
