Description

【０００１】
【産業上の利用分野】
本発明は、圃場の穀稈を刈取る前に、刈取り条毎に穀稈を分草し起立保持させるコンバインの穀稈引起装置に関する。
【０００２】
【従来の技術】
従来、機体の左右方向に引起タインを突出させる引起ケースの前面側に、機体の進行方向に分草タインを突出させる分草ケースを取付ける構造において、分草ケース下部は刈取フレーム先端部に取付けられる。この場合、両者をボルト締結するとアタッチメントとして取扱われる分草ケースの脱着が容易に行えない。そこで、両者をピンと孔または溝による係合により取付けるようにしていた。
【０００３】
【発明が解決しようとする課題】
分草ケース下部と刈取フレーム先端部を係合させる場合、ピンと孔から成る係合部では前後及び上下の移動を規制できるが、左右移動は規制することができず、また比較的重量のある分草ケースを支持した状態でピンと孔を側方から係脱させる必要があり着脱作業が容易に行えない。一方、ピンと溝から成る係合部では着脱作業は容易となるが、溝方向の移動を規制することができない。さらにピンと孔から成る係合部とピンと溝から成る係合部とを組合せたものでも、各係合部の欠点は補うことができない問題があった。
【０００４】
【課題を解決するための手段】
然るに、本発明は、機体の左右方向に引起タインを突出させる引起ケースの前面側に、機体の進行方向に分草タインを突出させる分草ケースを取付けるコンバインの穀稈引起装置において、前記分草ケースの下部及び刈取フレーム先端部を前後２箇所で係合させる後側係合部と前側係合部を設け、分草ケースを上方から刈取フレームに載せる動作で刈取フレームの後側係合部に分草ケースの後側係合部を係合させると共に、係合状態の後側係合部を支点とする分草ケースの後方回動動作で刈取フレームの前側係合部に分草ケースの前側係合部を下方から係合させるもので、分草ケースを上方から刈取フレームに載せ、後方に回動させることにより、前後２箇所の係合部が係合され、この容易な係合作業によって分草ケースの着脱が容易に行い得ると共に、前後２箇所の係合部の係合方向が上下逆方向になることで、前後左右及び上下の移動規制とガタツキ防止も図られ、分草ケースを確実に固定し得るものである。
【０００５】
【実施例】
以下本発明の実施例を図面に基づいて詳述する。図１は分草ケースの下部取付け構造を示す説明図、図２はコンバインの全体側面図、図３は同平面図であり、図中（１）は走行クローラ（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）に架設する機台、（４）はフィードチェン（５）を左側に張架し扱胴（６）及び処理胴（７）を内蔵している脱穀部、（８）は刈刃（９）及び穀稈搬送機構（１０）などを備える刈取部、（１１）は昇降支点筒軸（１２）を介して刈取部（８）を昇降させる油圧シリンダ、（１３）は排藁チェン（１４）終端を臨ませる排藁処理部、（１５）は脱穀部（４）からの穀粒を揚穀筒（１６）を介して搬入する穀物タンク、（１７）は前記タンク（１５）の穀粒を機外に搬出する排出オーガ、（１８）は運転操作部（１９）及び運転席（２０）を備える運転台、（２１）は運転席（２０）下方に設けるエンジンであり、連続的に穀稈を刈取って脱穀するように構成している。
【０００６】
また、図中（２２）は刈取部（８）の前部に立設固定させる引起ケースで、機体左右方向に突設させる引起タイン（２３）を設け、分草板（２４）を介して取込む未刈穀稈を前記引起タイン（２３）により起立保持させるものであり、さらに図中（２５）は前記引起ケース（２２）の前面側に脱着自在に取付けられるアタッチメントである分草ケースで、機体進行方向に突設させる分草タイン（２６）を設け、前記分草板（２４）と分草タイン（２６）により各刈取条毎に穀稈を分草させるもので、これら引起ケース（２２）と分草板（２４）と分草ケース（２５）とで刈取部（８）前部に前処理部（２７）を構成している。
【０００７】
図１及び図４及び図５に示す如く、刈取フレーム（２８）の先端部にブラケット（３０）を設けると共に、分草ケース（２５）の下部一側面にブラケット（３１）を設け、これら各ブラケット（３０）（３１）を前後２箇所で係合させ、分草ケース（２５）の下部を刈取フレーム（２８）の先端部に取付ける。その後側係合部はＵ字形の溝（３２）と大径頭部付きセットピン（３３）から成り、溝（３２）が刈取フレーム（２８）側のブラケット（３０）後部に設けられ、セットピン（３３）が分草ケース（２５）側のブラケット（３１）後部に設けられ、分草ケース（２５）を上方より刈取フレーム（２９）へ載せる動作で、溝（３２）にセットピン（３３）を係合させることができ、そのセットピン（３３）を支点に分草ケース（２５）を前後方向に回動させることができ、また分草ケース（２５）を上方に持上げる動作で溝（３２）からセットピン（３３）を上方に外すことができるように形成されている。
【０００８】
一方、前側係合部は大径頭部付き係合ピン（３４）とフック溝（３５）を有するフック（３６）から成り、係合ピン（３４）が刈取フレーム（２８）側のブラケット（３０）前部に設けられ、フック（３６）が分草ケース（２５）側のブラケット（３１）前部に設けられ、係合状態の後側係合部のセットピン（３３）を支点とする分草ケース（２５）の後方回動動作で係合ピン（３４）に下方からフック（３６）を係合させることができ、また前記セットピン（３３）を支点とする分草ケース（２５）の前方回動動作で係合ピン（３４）からフック（３６）を下方に外すことができるように形成されている。
【０００９】
上記から明らかなように、各係合部がそれぞれ分草ケース（２５）の前後の移動を規制する作用を得ると共に、これら係合部を前後２箇所に配置させたことで一方の係合部が他方の係合部の前後方向のガタツキを防止する作用を得ている。また前後の係合部は係合方向が上下逆方向となるように形成されており、分草ケース（２５）の上下の移動を規制する作用を得ると共に、分草ケース（２５）は後傾姿勢で支持される引起ケース（２２）の前面側でこれと平行に取付けられ、その分草ケース（２５）の重心よりも後側係合部が前側に位置し、分草ケース（２５）の重量が前後の係合部を係合させる方向に働くように前後の係合部が形成されており、前後の係合部の係合力を高める作用と、分草ケース（２５）の上下のガタツキを防止する作用とが得られる。さらに前後の係合部の各ピン（３３）（３４）の大径頭部（３３ａ）（３４ａ）により分草ケース（２５）の左右のガタツキを防止する作用を得ている。
【００１０】
さらに、分草ケース（２５）の上部一側面には平面視Ｌ形の駆動ケース（３７）が設けられ、該駆動ケース（３７）は分草ケース（２５）下部の後側係合部を支点とする分草ケース（２５）の後方回動動作で前側係合部が係合されるとき、引起ケース（２２）に対向する一端が、その引起ケース（２２）の前面上部に設けた受け部（３８）に嵌合され、且つ、この嵌合と同時に引起ケース（２２）の駆動軸（３９）に駆動ケース（３７）内部の入力側ベベルギヤ軸（４０）先端が軸継手（４１）を介して連結され、分草ケース（２５）の上部の取付けと、駆動連結とを同時に行う。
【００１１】
そして、駆動ケース（３７）と受部（３８）の固定はボルトによる締結でもよいが、工具が不要でワンタッチで脱着ができる固定手段が好ましく、この好ましい固定手段としては例えば特願平５−２４９９４０号明細書に示された割カラーがある。
【００１２】
本実施例は上記の如く構成しており、分草ケース（２５）を刈取フレーム（２８）に載せ、分草ケース（２５）下部と刈取フレーム（２８）下部との後側係合部（３２）（３３）を係合させ、その後側係合部（３２）（３３）を支点に分草ケース（２５）を後方回動させ、分草ケース（２５）下部と刈取フレーム（２８）先端部との前側係合部（３４）（３６）の係合と、駆動ケース（３７）による引起ケース（２２）の前面上部への分草ケース（２５）上部の取付け及び駆動連結とを同時に行い、最後に分草ケース（２５）の駆動ケース（３７）を引起ケース（２２）の受部（３８）に固定することにより、分草ケース（２５）の取付けが工具なしで容易に行えると共に、上記の取付作業を逆に行うことで分草ケース（２５）の取外しが工具なしで容易に行えるものである。
【００１３】
また、上記実施例における後側係合部は、分草ケース（２５）側のブラケット（３１）後部に逆Ｕ字状の溝を設け、刈取フレーム（２８）側のブラケット（３１）後部に大径頭部付きセットピンを設けても形成することができ、また前側係合部は、分草ケース（２５）側のブラケット（３１）前部に頭部付き係合ピンを設け、刈取フレーム（２８）側のブラケット（３１）前部に下向きのフック溝を有するフックを設けても形成することができる。
【００１４】
【発明の効果】
以上実施例から明らかなように本発明は、機体の左右方向に引起タイン（２３）を突出させる引起ケース（２２）の前面側に、機体の進行方向に分草タイン（２６）を突出させる分草ケース（２５）を取付けるコンバインの穀稈引起装置において、前記分草ケース（２５）の下部及び刈取フレーム（２８）先端部を前後２箇所で係合させる後側係合部（３２）（３３）と前側係合部（３４）（３６）を設け、分草ケース（２５）を上方から刈取フレーム（２８）に載せる動作で刈取フレーム（２８）の後側係合部（３２）に分草ケース（２５）の後側係合部（３３）を係合させると共に、係合状態の後側係合部（３２）（３３）を支点とする分草ケース（２５）の後方回動動作で刈取フレーム（２８）の前側係合部（３４）に分草ケース（２５）の前側係合部（３６）を下方から係合させるもので、分草ケース（２５）を上方から刈取フレーム（２８）に載せ、後方に回動させることにより、前後２箇所の係合部（３２）（３３）、（３４）（３６）が係合され、この容易な係合作業によって分草ケース（２５）の着脱を容易に行うことができると共に、前後２箇所の係合部（３２）（３３）、（３４）（３６）の係合方向が上下逆方向になることで、前後左右及び上下の移動規制とガタツキ防止も図られ、分草ケース（２５）を確実に固定できる等の効果を奏するものである。
