Description

【0001】
【発明の属する技術分野】
本発明は穀稈を連続的に刈取って脱穀すると共に、脱穀部からの穀粒を穀粒タンクに取出すコンバインに関する。
【0002】
【従来の技術】
従来、実開昭55−147152号公報、または実開昭64−32039号公報に示す如く、排出オーガを駆動及び停止操作するクラッチレバーを排出オーガ先端出口部に取付け、排出オーガ先端側でもオーガクラッチの入切を行える技術がある。また、実開昭61−743385号公報に示す如く、排出オーガの昇降及び旋回の各操作を行う操作レバーを排出オーガ先端側にも取付け、排出オーガ先端側でもオーガ昇降及び旋回操作を行える技術がある。
【0003】
【発明が解決しようとする課題】
前記従来技術は、排出オーガの駆動及び停止並びに昇降及び旋回の各操作を排出オーガ先端側でも行えるから、トラック荷台などに穀粒タンクの穀粒を搬出する作業を1人の作業者でも行えるが、運転席側と排出オーガ先端側の両方で排出オーガの操作が並行して行えるから、2人の作業者が運転席と排出オーガ先端側のトラック荷台とに夫々いる場合、運転席側の作業者が排出オーガの昇降または旋回操作を行うと、トラック荷台上の作業者に排出オーガ先端側が衝突する不具合がある。
【0004】
そこで、特開平3−130011号公報に示す如く、運転席側の操作を禁止する手動操作式の優先スイッチを排出オーガ先端側に取付け、前記スイッチ操作によって運転席側の操作を禁止し、排出オーガ先端側だけで操作を行い、運転席側の誤操作を防ぐ技術もあるが、穀粒排出作業が終了したとき、優先スイッチを切り忘れてトラック荷台などから作業者が降りて排出オーガ先端から離れ、運転席側に作業者が移動すると、運転席側での排出オーガの操作が禁止された状態が維持されているから、運転席側で排出オーガの操作を行い得ず、トラック荷台上の排出オーガ先端に作業者が戻って優先スイッチを切り、運転席側に作業者が再び戻って排出オーガの操作を行う必要があり、取扱い操作の簡略化並びに穀粒排出作業性の向上などを容易に図り得ない等の問題がある。
【0005】
【課題を解決するための手段】
そこで、本発明では、穀粒タンクの穀粒を搬出する排出オーガを昇降せる昇降部材設けると共に、本機側のオーガ位置操作部材の手動操作によって昇降部材を作動させる一方、排出オーガ側のオーガ位置操作部材手動操作によって昇降部材作動させるコンバインにおいて、本機側のオーガ位置操作部材の手動操作と、排出オーガ側のオーガ位置操作部材の手動操作とが逆操作されたときには、昇降部材の動作を中止させるようにしたことを特徴とするコンバインを提供するものである。
【0006】

以下、本発明の実施例を図面に基づいて詳述する。図1は穀粒排出オーガの制御回路図、図2は全体側面図、図3は同平面図であり、図中(1)は左右に走行クローラ(2)(2)を装設するトラックフレーム、(3)は前記トラックフレーム(1)に固定支持する機台、(4)はフィードチェン(5)を左側に張架し扱胴(6)を内蔵してなる脱穀部、(7)は機台(3)前方に昇降可能に支持させて刈刃及び穀稈搬送機構などを備える刈取部、(8)は前記フィードチェン(5)終端に連結させる排藁チェン(9)の終端を臨ませる排藁カッター部、(10)はコンバインの各部を駆動するエンジン、(11)は揚穀筒(12)を臨ませて脱穀部(4)から取出す穀粒を貯留する穀粒タンク、(13)は運転席(14)及び運転操作部(15)を備える運転台であり、前記刈取部(7)で連続的に穀稈を刈取ると共に、この刈取穀稈を前記脱穀部(4)で脱穀処理するように構成している。
【0007】

【0009】
さらに、図6に示す如く、前記タンク(11)前側の横送りオーガ(16)前端側に入力プーリ(38)を取付け、エンジン(10)の駆動力を伝える駆動プーリ(39)にベルト(40)を介して入力プーリ(38)を連結させ、連動連結させている各オーガ(16)(17)(18)を入力プーリ(38)によって駆動してタンク(11)の穀粒を搬出すると共に、前記ベルト(40)のテンションローラで形成するオーガクラッチ(41)を設け、クラッチモータ(42)にオーガクラッチ(41)を連結させ、前記クラッチモータ(42)制御によるオーガクラッチ(41)の入切操作によって各オーガ(16)(17)(18)を駆動または停止させるように構成している。
【0010】
また、図4に示す如く、脱穀部(4)上側で機体の対角線方向に上部排出オーガ筒(24)を上向きVノッチ付きのオーガレスト(43)によって収納支持させると共に、上部排出オーガ(18)の旋回動作を規制するストッパ(44)(45)を縦排出オーガ筒(19)と支柱(22)に設け、上部排出オーガ(18)の旋回動作の機械的限界位置を前記ストッパ(44)(45)によって設定するように構成している。
【0011】
さらに、図1に示す如く、昇降シリンダ(29)及び旋回モータ(34)を自動制御して上部排出オーガ(18)をオーガレスト(43)位置に復帰させる自動収納スイッチ(46)と、昇降シリンダ(29)及び旋回モータ(34)を自動制御して上部排出オーガ(18)を穀粒排出位置に移動させる自動セットスイッチ(47)と、昇降シリンダ(29)を手動制御して上部排出オーガ筒(24)先端の投出口(32)を昇降させるオーガ上昇及び下降スイッチ(48)(49)と、旋回モータ(34)を手動制御して上部排出オーガ(18)を旋回させるオーガ左旋回及び右旋回スイッチ(50)(51)と、昇降シリンダ(29)または旋回モータ(34)の作動速度を手動操作によって変更させる速度切換スイッチ(52)と、昇降シリンダ(29)の上昇作動速度を手動操作によって変更させる上昇時間切換スイッチ(53)と、運転操作部(15)の走行変速レバー(54)が走行変速中立位置であることを検出する走行中立スイッチ(55)と、クラッチモータ(42)を手動制御してオーガクラッチ(41)を入切動作させるオーガクラッチ入及び切スイッチ(56)(57)を備え、マイクロコンピュータで形成する運転席コントローラ(58)に前記各スイッチ(46)〜(57)を接続させると共に、運転操作部(15)の左操作コラム(59)に前記コントローラ(58)を取付け、運転席(14)の作業者が各スイッチ(46)〜(57)操作を行うように構成している。
【0012】
また、自動収納スイッチ(46)オン操作を表示する自動収納ランプ(60)と、自動セットスイッチ(47)オン操作を表示する自動セットランプ(61)と、オーガクラッチ(41)入動作を表示するオーガクラッチランプ(62)を、前記コントローラ(58)に接続させると共に、上部排出オーガ(18)の旋回位置(旋回角度)を検出させるポテンショメータ型旋回位置センサ(63)と、上部排出オーガ(18)のセット位置(穀粒排出位置)を手動設定する位置調節ボリューム(64)と、昇降シリンダ(29)及び旋回モータ(34)の動作速度の基準パルス幅を機種などに応じて変更するパルス調節ボリューム(65)を、前記コントローラ(58)に接続させるもので、図5の如く、旋回モータ(34)の出力軸(35)上に前記旋回位置センサ(63)を取付けている。
【0013】
さらに、上昇及び下降回路(66)(67)を介して昇降シリンダ(29)を、左右旋回回路(68)(69)を介して旋回モータ(34)を、オーガクラッチ入切回路(70)(71)を介してクラッチモータ(42)を、また旋回ブレーキ(37)及び警報用ブザー(72)を、前記コントローラ(58)に接続させる。
【0014】
また、前記上部排出オーガ筒(24)先端の投出口(32)に取付ける手動操作部であるオーガ先端コントローラ(73)を備え、該コントローラ(73)を運転席コントローラ(58)に接続させると共に、運転席コントローラ(58)の手動操作用の各スイッチ(48)(49)(50)(51)(56)(57)と同一操作を行うオーガ上昇及び下降スイッチ(74)(75)、並びにオーガ左旋回及び右旋回スイッチ(76)(77)、並びにオーガクラッチ入及び切スイッチ(78)(79)を、オーガ先端コントローラ(73)に設けるもので、例えばトラック荷台またはコンテナ上側に投出口(32)を位置させているとき、該部で作業者によって各スイッチ(74)〜(79)操作を行い、トラック荷台またはコンテナの角隅部などに穀粒を投入させるように構成している。
【0015】
また、無線によって遠隔操作を行う遠隔コントローラ(80)を備え、該コントローラ(80)からの電波信号を受信入力させる受信回路(81)を運転席コントローラ(58)に接続させると共に、運転席コントローラ(58)の手動操作用の各スイッチ(48)(49)(50)(51)(56)(57)と同一操作を行うオーガ上昇及び下降スイッチ(82)(83)、並びにオーガ左旋回及び右旋回スイッチ(84)(85)、並びにオーガクラッチ入及び切スイッチ(86)(87)を、遠隔コントローラ(80)に設けるもので、例えば運転席(14)或いはトラック荷台またはコンテナから離れた場所に作業者が位置し、該遠隔部で作業者によって各スイッチ(82)〜(87)操作を行い、上部排出オーガ(18)の昇降及び左右旋回並びにオーガクラッチ(41)の入切を作業者の遠隔手動操作によって夫々行うように構成している。
【0016】
さらに、図7に示す如く、上部排出オーガ(18)の旋回範囲を270度に設定したもので、オーガレスト(43)の収納位置を旋回角度零度とし、最大旋回位置であるセット限界位置を旋回角度270度とし、投出口(32)が機体上方に位置する排出不可能域と、左側及び後側及び右側の各排出域によって上部排出オーガ(18)の旋回範囲を形成すると共に、収納位置またはセット限界位置に上部排出オーガ(18)が旋回移行するとき、高速旋回する定速動作域から減速動作域及び遅速動作域に移動して2段階に旋回速度が減速され、上部排出オーガ(18)の旋回慣性力を段階的に小さくして旋回動作を停止させるように構成している。
【0017】
さらに、図8のフローチャートに示す如く、旋回位置センサ(63)出力が図7のように設定された正常値であり、上部排出オーガ(18)先端の各スイッチ(75)〜(79)手動操作、操作コラム(59)の各スイッチ(48)〜(51)(56)(57)手動操作、リモートコントロール用の各スイッチ(82)〜(87)遠隔手動操作のいずれも行われていない場合、自動収納スイッチ(46)が操作されることにより、旋回位置センサ(63)出力が収納位置ではないとき、昇降シリンダ(29)及び旋回モータ(34)を自動制御して前記オーガ(18)をオーガレスト(43)に支持させる収納動作を自動的に行わせ、この自動収納のとき並びに前記オーガ(18)が収納位置のときはオーガクラッチ(41)が入操作されても切動作されて切保持されると共に、前記の手動操作が行われていない場合で自動セットスイッチ(47)が操作されることにより、位置調節ボリューム(64)と旋回位置センサ(63)の出力に差があり、旋回位置センサ(63)出力が収納位置またはセット限界位置に到達していないとき、昇降シリンダ(29)及び旋回モータ(34)を自動制御し、位置調節ボリューム(64)のセット位置に前記オーガ(18)を移行させるセット動作を自動的に行わせ、また前記オーガ(18)がセット位置またはセット限界位置のとき、オーガクラッチ入切スイッチ(56)(57)手動操作によりオーガクラッチ(41)の入動作または切動作を行わせるもので、前記の自動収納動作及び自動セット動作時、前記オーガ(18)が収納位置またはセット位置に対して所定以上離れているときは定速動作域として連続動作によって高速で旋回モータ(34)を作動させ、また前記オーガ(18)が収納位置またはセット位置に接近したときは減速動作域及び遅速動作域としてパルス動作によって段階的に減速して旋回モータ(34)を作動させるように構成している。なお、自動収納動作時に自動収納スイッチ(46)オン操作によって自動収納が中止されると共に、自動セット動作時に自動セットスイッチ(47)がオン操作されることによって自動セットが中止されるように構成している。
【0018】
また、操作コラム(59)の各スイッチ(48)〜(51)手動操作が行われたとき、前記の自動収納及びセット動作が中止され、旋回位置センサ(63)が収納位置またはセット位置に到達していないとき、図7の定速及び減速及び遅速の各動作域の速度で旋回モータ(34)を作動させ、定速動作域において各スイッチ(50)(51)がオフになるまで連続動作によって高速で旋回モータ(34)を作動させる高速手動動作が行われると共に、前記オーガ(18)が収納位置のときはオーガクラッチ(41)が入操作されても切動作されて切保持される一方、前記高速手動動作が行われたときまたはセット限界位置のとき、オーガクラッチ入切スイッチ(56)(57)手動操作によりオーガクラッチ(41)の入動作または切動作を行わせるように構成している。
【0019】
また、上部排出オーガ(18)先端の各スイッチ(75)〜(79)手動操作、またはリモートコントロール用の各スイッチ(82)〜(87)遠隔手動操作のいずれかが行われた場合、旋回位置センサ(63)が収納位置またはセット位置に到達していないとき、操作コラム(59)側のスイッチ(48)〜(51)の逆操作によって制御が中止される以外は、図7の遅速動作域と同一のパルス動作によって旋回モータ(34)の低速手動動作が行われると共に、前記オーガ(18)が収納位置のときはオーガクラッチ(41)が入操作されても切動作されて切保持される一方、前記低速手動動作が行われたときまたはセット限界位置のとき、オーガクラッチ入切スイッチ(56)(57)手動操作によりオーガクラッチ(41)の入動作または切動作を行わせるように構成している。
【0020】
上記の図8のフローチャートの記載から明らかなように、穀粒タンク(11)の穀粒を搬出する排出オーガ(18)を昇降及び旋回させる昇降部材である昇降シリンダ(29)及び旋回部材である旋回モータ(34)と、排出オーガ(18)に駆動力を伝達制御するクラッチ部材であるクラッチモータ(42)を設けると共に、本機側のオーガ位置操作部材であるオーガ上昇及び下降スイッチ(48)(49)並びにオーガ左及び右旋回スイッチ(50)(51)とクラッチ操作部材であるオーガクラッチ入及び切スイッチ(56)(57)の手動操作によって昇降シリンダ(29)と旋回モータ(34)とクラッチモータ(42)を作動させる一方、排出オーガ(18)先端側のオーガ位置操作部材であるオーガ上昇及び下降スイッチ(74)(75)並びにオーガ左及び右旋回スイッチ(76)(77)とクラッチ操作部材であるオーガクラッチ入及び切スイッチ(78)(79)の手動操作によって昇降シリンダ(29)と旋回モータ(34)とクラッチモータ(42)を作動させるコンバインにおいて、排出オーガ(18)をオーガ位置センサである旋回位置センサ(63)によって検出させて排出オーガ(18)を自動的に移動させる自動制御スイッチである自動収納及び自動セットスイッチ(46)(47)を本機の運転操作部(15)に設けると共に、排出オーガ(18)先端側のオーガ位置操作用の前記各スイッチ(74)(75)(76)(77)とクラッチ操作用の各スイッチ(78)(79)の操作入力を、運転操作部(58)側の操作入力に対して優先させて、昇降シリンダ(29)及び旋回モータ(34)及びクラッチモータ(42)の各制御出力として出力させる。そして、1人の作業者が排出オーガ(18)先端側で穀粒排出作業を行っているとき、もう1人の作業者が運転席(14)側で排出オーガ(18)操作を行っても、排出オーガ(18)先端側の作業者による制御が優先して行われ、運転席(14)側での誤操作または不適正な操作による排出オーガ(18)制御を阻止し、穀粒排出位置が不適正になったり排出オーガ(18)先端側が作業者に衝突する等の不具合をなくすと共に、穀粒排出終了時に従来のような優先スイッチの禁止解除を忘れて運転席(14)と排出オーガ(18)先端側を作業者が往復する等の面倒をなくし、取扱い操作の簡略化並びに穀粒排出作業性の向上などを図り、さらに従来の優先スイッチを省くことによって制御回路構造の簡略化及び製造コストの低減並びに操作仕様内容の変更などを図る。
【0021】
さらに、図9のフローチャートに示す如く、操作コラム(59)で各スイッチ(48)〜(51)操作が行われたとき、各スイッチ(48)〜(51)操作に基づき連続動作によって昇降シリンダ(29)または旋回モータ(34)を高速運転し、この途中で前記オーガ(18)先端のスイッチ(74)〜(77)操作またはリモートコントロールのスイッチ(82)〜(85)操作が行われることにより、各操作が同一方向のときはパルス動作によって昇降シリンダ(29)または旋回モータ(34)を低速運転すると共に、前記オーガ(18)先端のスイッチ(74)〜(77)操作またはリモートコントロールのスイッチ(82)〜(85)操作が行われているとき、操作コラム(59)で各スイッチ(48)〜(51)操作が行われても、各操作が同一方向のときはパルス動作によって昇降シリンダ(29)または旋回モータ(34)を低速運転するように構成している。
【0022】
また、操作コラム(59)の各スイッチ(48)〜(51)操作と、前記オーガ(18)先端のスイッチ(74)〜(77)操作またはリモートコントロールのスイッチ(82)〜(85)操作が略同時に行われ、各操作が同一方向の操作ではない場合、操作コラム(59)側とオーガ(18)先端側(または遠隔操作)で、一方が昇降シリンダ(29)操作を行い、他方が旋回モータ(34)操作を行う異なる操作状態において、昇降シリンダ(29)及び旋回モータ(34)の両方を低速運転し、前記オーガ(18)の昇降と旋回を同時に行わせると共に、操作コラム(59)側とオーガ(18)先端側(または遠隔操作)で、一方が昇降シリンダ(29)の上昇操作で他方が該シリンダ(29)の下降操作のとき、または一方が旋回モータ(34)の左旋回操作で他方が該モータ(34)の右旋回操作のとき、逆方向に同時操作された昇降シリンダ(29)または旋回モータ(34)を停止保持するように構成している。
【0023】
上記から明らかなように、排出オーガ(18)の穀粒排出動作及び排出オーガ(18)位置を制御する本機操作部である運転席コントローラ(58)とオーガ先端操作部であるオーガ先端コントローラ(73)を運転操作部(15)と排出オーガ(18)先端部に夫々配設させ、昇降シリンダ(29)、旋回モータ(34)、クラッチモータ(42)に、運転席コントローラ(58)とオーガ先端コントローラ(73)を制御出力接続させる運転席コントローラ(53)を設け、従来の中央管理用の制御回路を不要にし、電気配線構造の簡略化並びに設置組込み作業の簡略化などを行い、取扱い操作性の向上並びに製造コストの低減などを図る。また、排出オーガ(18)の手動操作スイッチであるオーガ上昇及び下降スイッチ(48)(49)及び左右旋回スイッチ(50)(51)及びオーガクラッチ入及び切スイッチ(56)(57)と自動制御スイッチである自動収納及び自動セットスイッチ(46)(47)の両方を運転席コントローラ(58)に入力接続させるコンバインにおいて、排出オーガ(18)の手動操作スイッチであるオーガ上昇及び下降スイッチ(74)(75)及び左右旋回スイッチ(76)(77)及びオーガクラッチ入及び切スイッチ(78)(79)だけをオーガ先端コントローラ(73)に入力接続させ、各操作部(58)(73)で逆操作が行われたときに各操作部(58)(73)の制御出力による動作を中止させる。そして、排出オーガ(18)先端側操作に対して本機側で逆操作を行うことによって排出オーガ(18)を停止させ、本機側の作業者が監視し乍ら排出オーガ(18)先端側で補助作業者が排出作業を行うとき、補助作業者の不適正な操作並びに排出オーガ(18)の誤作動を本機側の作業者によって阻止し、取扱い操作の簡略化並びに穀粒排出作業性の向上などを図る。
【0024】
【発明の効果】
本発明では、穀粒タンク(11)の穀粒を搬出する排出オーガ(18)を昇降させる昇降部材(29)を設けると共に、本機側のオーガ位置操作部材(48)(49)の手動操作によって昇降部材(29)を作動させる一方、排出オーガ(18)側のオーガ位置操作部材(74)(75)の手動操作によって昇降部材(29)を作動させるコンバインにおいて、本機側のオーガ位置操作部材(48)(49)の手動操作と、排出オーガ(18)側のオーガ位置操作部材(74)(75)の手動操作とが逆操作されたときには、昇降部材(29)の動作を中止させるようにしているため、本機側の作業者が監視し乍ら排出オーガ(18)先端側で補助作業者が排出作業を行うとき、例えば、補助作業者の不適正な操作並びに排出オーガ(18)の誤作動などがあった場合は、本機側の作業者によって阻止することもでき、取扱い操作の簡略化、並びに、穀粒排出作業性の向上などを容易に図ることができる。
