本発明は、圃場に栽培されている人参を、走行する機体の前端部に装設した掘取器で掘り出し、それの後方に連続するように設けた引抜き搬送装置により、それの葉部を挟持して抜き上げながら後送し、その移送の間に、引抜き搬送装置の下面側に設けたカッターにより、引抜き搬送装置に挟持されている葉部から根部を切り離し、それにより落下する根部をコンテナに収集するようにした人参収穫機において人参を、引抜き搬送装置により抜き上げて後送する間にその人参の葉部と根部との間をカッターにより切断して切り落とす根部切り落とし装置についての改良に関する。
【0002】
【従来の技術】
従前の人参収穫機における引抜き搬送装置の切断装置は、引抜き搬送装置の一対に対向する挟持ベルトの終端側の下面に、その挟持ベルトに葉部が挟持されて後送される人参の根部の肩面に対し上から当接するガイドを、挟持ベルトに対し所定の角度に傾斜させて挟持ベルトの機枠に固定装設しておいて、これにより人参の葉部を下方にしごき、それの後端部の後方に、前記機枠に支架した円板状のカッターの刃縁を臨ませ、しごいた葉部の基端部位から根部を切り離すようにしている。
【0003】
【発明が解決しようとする課題】
上述の従前の人参収穫機における引抜き搬送装置における切断装置は、引抜き搬送装置で後送されてくる人参が、それの根部の肩に接するガイドにより下方にしごかれて、引抜き搬送装置に対する位置がきめられた葉部の基端部位に、カッターの刃縁が作用していくようになることから、切り離した人参の根部を、それに残る茎部が略一定の長さに切り揃えられた状態とし収穫し得るようになるが、収穫時期を早めたときに、葉部が千切れて、根部の頭に残る茎部の長さが不揃いになる問題がでてくる。
【0004】
この問題は、収穫時期を早めると、人参の葉が稚いことで柔らかく、そのため、ガイドに根部の肩が当接して、人参が下方にしごかれたときに、引抜き搬送装置の挟持ベルトに挟持されている葉部が、そのしごきにより千切れるようになることで生ずる。
【0005】
本発明は、従来手段に生じているこの問題を解決するためになされたものであって、人参の収穫を早い時期に行なっても、稚く柔らかい葉部に千切れを生ぜしめずに、収穫する人参の根部の頭に残す茎部の長さが略一定の長さに揃えられた状態となるようにする新たな手段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】
そして、本発明においては、上述の目的を達成するための手段として、車体aに、前端部には人参の根部Rを掘り出す掘取器hを設け、その掘取器hの後方には、掘り出した人参の葉部を挟持して引抜き搬送する一対の挟持ベルト21・21よりなる引抜き搬送装置gを後方に向け傾斜上昇する姿勢に装架し、その引抜き搬送装置の後端側の下面側に、それにより搬送される人参の根部Rの肩面に上から当接するガイドiを、側面視において、その引抜き搬送装置の挟持ベルト21・21に対し後方に向い次第に下方に離れるよう所定角度αに傾斜させて配設するとともに、そのガイドiの後方に搬送されてくる人参の根部Rを葉部から切り離す円盤状のカッターjを配設してなる人参の収穫機において、前記ガイドiを、引抜き搬送装置gの機枠20と別体に形成し、そのガイドiの前端側を支軸30を介し前記機枠20に後端側が昇降回動するよう軸支して、そのガイドiの後端部にカッターjの駆動部40を組付ける組付機枠41を一体的に装設し、その組付機枠41にカッターjを組付け支架し、このガイドiの後端部を、引抜き搬送装置gの機枠20に対し昇降調節自在に連結せしめたことを特徴とする人参収穫機における引抜き搬送装置の根部切り落とし装置を提起するものである。
【0007】
【発明の実施の形態】
本発明手段は、自在に走行する車体に、左右に一対に対向する挟持ベルトよりなる引抜き搬送装置を、側面視において前端側が低く後端側が高くなるよう後方に向け傾斜上昇する姿勢に装架し、それの前端側に、掘取刃および分草杆等よりなる掘取器を設け、その引抜き搬送装置の後端側の下面側に、側面視において、後方に向うに従い挟持ベルトに対して下方に離れるよう所定角度に傾斜させてガイドを配位して、引抜き搬送装置の機枠に支架し、そのガイドの後端部に、前記機枠に支架したカッターの刃縁を臨ませるようにすることについては、従前の人参収穫機と同様に構成してよい。
【0008】
しかし、引抜き搬送装置の後端側の下面に配設するガイドは、それの前端側を支軸に軸架して後端側がその支軸中心に上下に回動し、かつ、所望の回動位置で固定し得るようにすることで、側面視における引抜き搬送装置の挟持ベルトに対する該ガイドの角度を調節可能にする。
【0009】
そして、このガイドの後端部に刃縁を臨ませるカッターは、それを支持する組付機枠を、このガイドに一体または一体的に形設しておいて、ガイドの挟持ベルトに対する傾斜角度を変動させたときに、ガイドの後端部に対するカッターの刃縁の関係位置が略一定に保持されるようにする。
【0010】
このとき、カッターの組付機枠に対する組付け固定は、それの組付け位置の調節を可能にし、これにより、ガイドの後端部に対する刃縁の作用位置および作用角度の調節が行なえるようにしてよい。
【0011】
また、カッターは、通常の円板状の回動刃を用いた形態のものでよく、そのカッターは一枚の回転刃を用いる形態のもの、または2枚の回転刃が左右に対向する形態のものなど適宜に構成してよい。
【0012】

【0013】
車体aの他側に装架せる引抜き搬送装置gは、図2にあるように、側面視において前後に長い略ヘの字状の角パイプよりなる支持アーム10を、それの後端側に設けた支点軸11により自在に回動するよう車体aに支架し、その支持アーム10の前端側に、車体aに基端側を支架せる油圧シリンダ12のロッド120を、リンク杆13・14を介し連繋して、この油圧シリンダ12と前記支点軸11により車体aに支持アーム10を支架し、この支持アーム10の上面の後端寄りの部位に、上方に立上る支持機枠15を固定装設し、この支持機枠15の上端側に、該引抜き搬送装置gの機枠20を支架することで車体aの左右方向の他側に装設してある。
【0014】
この引抜き搬送装置gは、図1にあるように、前後方向に沿いエンドレスに回動する挟持ベルト21・21を左右に一対に並列支架し、前記機枠20の前端側に、掘取刃と分草杆等からなる掘取器hを設けて、その掘取器hで掘り出した人参の葉部を、一対に対向する前記挟持ベルト21・21で挟持して、その人参の根部Rを図2にあるように地中から抜き上げながら後方に搬送していく通常の形態のものであり、それの後端側の下面には、葉部が挟持されて吊下げ状態で後送されていく人参の根部Rを葉部から切り離す円盤状のカッターjが装設してある。
【0015】
ガイドiは、引抜き搬送装置gの一対の挟持ベルト21・21で葉部が挟持されて後送されていく人参の根部Rを、カッターjにより切り離すときに、その人参の葉部の基端部に対するカッターjの作用位置を略一定に規制するためのものであり、図2および図4に示している如く、引抜き搬送装置gの後端側の下面側で、左右の挟持ベルト21・21により葉部が挟持されて吊下げ状態となって後送される人参の根部Rの肩面よりも上方位置に、図3に示す如く、その人参の葉部の基端側が通過していくように所定の間隔をもって左右に一対に対向するガイドレール状に装設してある。
【0016】
このガイドiは、側面視において、図4にあるように、挟持ベルト21・21に対して、後方に向うに従い次第に下方に離れるように所定の角度αで傾斜させて機枠20に支架してあって、これにより人参が後送されるに従い、図4にて鎖線に示している如く、根部Rの肩面がこのガイドiに当接して下方に押し出されるようにしてある。
【0017】
そして、このガイドiは、前述の引抜き搬送装置gの機枠20とは別体に形成してあって、それの前端側が支軸30を介して機枠20に軸支され、また、後端側には、カッターjの駆動部40を組付ける組付機枠41が一体的に連結してあって、この組付機枠41を、前述の機枠20から垂設する支持機枠42に、多連に設けたボルト穴43…に対するセットボルト穴44の嵌め換えによって、連結位置を自在に調節し得るようにし、その調節で前述の角度αの変更が行なえるようにしてある。
【0018】
45は、カッターjの駆動部40を組付機枠41にセットするセットボルトで、これを挿通するボルト穴46は長穴に形成してあり、これにより、カッターjのガイドiに対する取付位置の調整が行なわれるようになる。
【0019】
次に図5乃至図7は別の実施例を示している。この例は、前述の実施例のカッターjが一枚の回転刃を用いたものであるのに対し、カッターjを2連にして、二枚の回転刃4・4が対向するようにした例である。
【0020】
図において、31・31は一対のガイドi・iを支持する支持板で、それぞれ前端側が支軸30を介して機枠20に軸支され、後端側にはカッターjの駆動部40の組付機枠41が設けられ、その組付機枠41を機枠20に垂設する支持機枠42に、セットボルト穴44…に対するボルト穴43の嵌め換えにより支軸30中心に回動して傾斜角度αの調節が行なわれるように連結支持させてある。
【0021】
しかし、一方の支持板31にあっては、機枠20に対し連結する側31aとガイドiに対して連結する側31bとに分けられて、これらが上下方向の連結軸32により、左右に回動自在に連結し、かつ、その連結軸32中心とする回動端側に、それらの間を拡張するコイルバネ33が介装してあって、これににより、一対に対向するガイドi・iの後端側の間隔が、コイルバネ33のバネ圧により弾性的に拡縮するようにしてある。
【0022】
【発明の効果】
以上説明したように、本発明による人参収穫機における引抜き搬送装置の切断装置は、引抜き搬送装置の一対の挟持ベルトで葉部が挟持されて後送されてくる人参に対してカッターの刃縁を作用させていくときに、その作用位置を略一定に規制するために挟持ベルトに対して傾斜させて設けておくガイドの角度αが、自在に変更調節でき、かつ、その角度αの調節がガイドとカッターとの関係位置を一定に保持して行なえるのであるから、収穫しようとする人参が稚く、そのため葉部が柔らかいときに、ガイドの挟持ベルトに対する傾斜角度αを浅くして、人参の根部を下方に引き出して、葉部をしごく量を少なくしてやることで、葉部に千切れが生じない状態として、切り離す根部の頭に残る茎部の長さを略一定に揃えて、根部を収穫していけるようになる。
