Description

【0001】
【産業上の利用分野】
本発明は、管理機において、耕幅に応じて容易に交換可能な耕耘カバーの構造に関する。
【0002】
【従来の技術】
従来、管理機の耕耘爪を畝幅に対応して交換可能にし、耕耘カバーのサイドカバーを外側に摺動させることで該カバーの幅を広げる事を可能にし、作業に応じた耕幅とする技術は公知となっていた。
更に、耕耘カバーに関して、中央より左右に延出するカバーを、前後方向に耕耘爪軸を中心に回動できる構成や、前記耕耘カバーをロータリーフレーム側部の蝶番を中心にはねあげ調節可能にした構成も公知となっている。
【0003】
【発明が解決しようとする課題】
しかし、従来の技術で、耕耘カバーを外側に摺動させて左右幅を調整自在にした構成においては、蝶ネジを締め付けることによって耕耘カバーとスライドカバーを固定していたので、作業中に弛むことがあり、また、泥が侵入し易いので、錆易く、ネジ山がつぶれることもあり、月日が過ぎるに従って調整し難くなっていた。
また、耕耘爪を爪軸上の爪ホルダーから外して交換する際には、耕耘カバーや尾輪の間から作業を行うので、作業スペースが狭く、耕耘爪の交換作業に手間がかかっていた。
また、左右のカバーを上方にはね上げる構造を利用して、耕耘爪の交換をする場合には、スペースは少しは広がるが、はね上げ角度には限界があるので、更に、メンテナンス性の優れたもので、尚且つ、耕耘爪の取り替えをした、左右幅に対応する構成の耕耘カバーが望まれていた。
【0004】
【課題を解決するための手段】
本発明は、以上のような課題を解決するために、次のような手段を用いる。
エンジン台20上にエンジンEを搭載し、該エンジンEの側部の伝動ケース22を介して、ミッションケースMに動力を伝動し、該ミッションケースMにて変速された動力は、後方下方に向かって突出するロータリーケース23cの下端に横架した耕耘爪軸26を駆 動し、該耕耘爪軸26の軸上には複数本の耕耘爪30を植設し、該ロータリーケース23cには、後方に突設されたロータリーフレーム27の先端部が固設され、該ロータリーフレーム27の後端部に、上下位置調節自在にゲージ輪28を配設し、前記耕耘爪30を被覆する耕耘カバー1は、左右中央位置に前後方向の支持杆2を配置し、該支持杆2は正面視コ字状で開口面が下方に向けて開口され、該支持杆2の開口形状を、該ロータリフレーム27の外形と合わせて形成し、該ロータリフレーム27の上方より、該支持杆2を嵌合して脱着自在に構成し、前記ロータリーフレーム27の上面にネジ孔を開口し、該ネジ孔とを一致させた孔2aを前記支持杆2の上面に開口し、上方より固定ネジ3を螺装して、支持杆2とロータリフレーム27とを固定し、前記耕耘カバー1は、耕耘爪軸26の長さや作業状況に合わせて選択脱着可能としたものである。
【0005】
【作用】
上記のような手段を用いることによって、本発明は、耕耘カバーの支持杆の上面の固定ネジを外すことで、耕耘カバーを容易に脱着することができる。
また、耕耘爪を植設した幅の異なる耕耘爪軸を装着した時に、その幅に合わせた耕耘カバーを選択して取り付けることができる。
【0006】
【実施例】
本発明の解決すべき課題及び構成は以上の如くであり、次に添付の図面に示した本発明の一実施例を説明する。
図1は本発明を採用した管理機の側面図、
図2は本発明の耕耘カバーを取り外した状態を示す管理機の側面図、
図3は本発明の耕耘カバーの正面部分断面図である。
【0007】
図1よりロータリ耕耘装置Bを備えた管理機Aの全体構成から説明する。
エンジン台20上にエンジンEが搭載されており、該エンジンEの上部に燃料タンク21が搭載されている。該エンジンEの側部の伝動ケース22を介して、ミッションケースMに動力が伝動され、該ミッションケースMにて変速された動力は、該ミッションケースMより前方下方に向かって突出するチェーンケース23bの、下端部に配置した走行輪24の車輪25を走行駆動させている。
また、前記ミッションケースMより後方下方に向かって突出するロータリーケース23cの下端には耕耘爪軸26を横架し、該耕耘爪軸26の軸上には複数本の耕耘爪30・30・・・が植設されている。
【0008】
また、本実施例においては、前記チェーンケース23bとロータリーケース23cは、側面視略「く」字状に屈曲した駆動ケース23として一体構成となっており、側面視略「く」字状に屈曲する屈曲部23aに前記ミッションケースMを配置している。
そして、前記耕耘爪軸26は、耕耘幅に合わせて、長さの異なる耕耘爪軸に交換するこができ、また、揚土作業や中耕作業等の他の作業に合った耕耘爪を装着した耕耘爪軸とも交換することができる。
【0009】
前記ミッションケースMの上部には、全方向に回動可能にハンドルベース31が設けられていて、該ハンドルベース31上端より、ハンドル32が後方へ突設されている。前記ハンドルベース31の近傍には主変速レバー33及び回動レバー34を突出させている。
また、前記ミッションケースMにホーク軸35、耕耘変速ホーク軸36を横架し、前記主変速レバー33を操作することで該走行ホーク軸35、耕耘変速ホーク軸36を摺動させて前記走行輪24及び耕耘爪30・30・・・を変速駆動させている。
【0010】
そして、前記ロータリーケース23cには、ロータリーフレーム27の先端部が固設されて後方に突出し、該ロータリーフレーム27の後端部には、上下位置調節自在にゲージ輪28を配設している。
そして、前記耕耘爪30・30・・・は、耕耘カバー1により被装されている。該耕耘カバー1の構造は、図2、図3に示すように、前後方向に支持杆2を配設し、該支持杆2の外側には、前後端部をそれぞれ斜め下方に湾曲した形状を有す上カバー6a・6aを付設しており、該上カバー6a・6aの外側にサイドカバー6b・6bを設けている。該上カバー6a・6aはヒンジ5・5を介して前記支持杆2側部に連結し、前記ヒンジ5・5の枢結部を支点として、上方向に回動可能とされている。前記支持杆2の上面には、上カバー6aのはね上げ角度を調節するための高さ調節板9の基部を取付固定している。
【0011】
前記左右の上カバー6a・6aの上面には、図3に示す如く、枢支部7・7を固着しており、該枢支部7には、スイングアーム8の基端部を枢結し、左右の該スイングアーム8の先端側には、長孔8a・8aを開口している。
該長孔8a・8aは、支持杆2の上方で重合され、そこに調節ツマミ10のネジ部を嵌挿して前記長孔8a・8aが枢支されている。前記調節ツマミ10のネジ部は、前記高さ調節板9に開口する長孔9aに嵌挿されている摺動部材に螺着している。
【0012】
そして、前記調節ツマミ10と摺動部材の間にスイングアーム8の長孔8a・8aを挟持して、前記調節ツマミ10を緩めるこで、摺動部材とともに上下方向に摺動可能になり、左右のサイドカバー6・6を同時に上げ下げして、はね上げ角度の調整を行うことができ、調節ツマミ10を締め付けることで、その角度に固定することができる。
【0013】
そして、本発明の耕耘カバー1は、図2に示す如く前記ロータリーフレーム27に脱着自在にしたものである。該耕耘カバー1の支持杆2を、図3に示すように、正面視コ字状で前記ロータリーフレーム27の外形と合わせて形成し、コ字状の該支持杆2の開口面を下方に向けて配置し、前記ロータリーフレーム27の上方より嵌合可能にし、前記支持杆2の上面には前後両端部に孔2a・2aを開口し、前記ロータリーフレーム27の上面に開口するネジ孔とを一致させて、上方より固定ネジ3・3を挿入し、ロータリーフレーム27に開口したネジ孔に螺合させることで耕耘カバー1を固定する構成としている。
【0014】
また、前記上カバー6a・6aと幅が異なり、耕耘爪軸26の長さに合わせた耕耘カバー(図示せず)や、他の作業状態に合った形状の耕耘カバー(図示せず)を数種類用意して、前述する如く作業状況に合わせて交換して前記耕耘爪軸26に合う耕耘カバーを選択して、前述する如くロータリーフレーム27の上方より取付けて、前記固定ネジ3・3を孔2a・2aに挿入し、ロータリーフレーム27に螺合することで、適切な大きさの耕耘カバーを簡単に挿着することができる。
また、該耕耘カバー1の固定方法は固定ネジ3に限る。また、前記耕耘爪30・30・・・及び耕耘カバー1を取り外して、ロータリーフレーム27に他の作業機を固定して牽引作業をすることもできる。
【0015】
【発明の効果】
以上のように構成することによって、次のような効果を奏するものである。
本発明は、固定ネジ3の上方からの脱着操作のみで、耕耘カバーを容易に脱着することが可能となって、耕耘カバーを取り外した際には耕耘爪を開放した状態にすることができ、耕耘爪の交換作業や清掃やメンテナンス作業を容易にすることができ、その作業能率を向上することができる。
また、耕耘爪軸の長さを変更したときにも、その長さに合わせて耕耘カバーを選択して容易に変更することができ、また、作業用途に合わせた耕耘カバーとも交換することができ、様々な農耕作業に対応する管理機を提供することができる。
