〔産業上の利用分野〕
この発明は、農業機械に関するものであって、耕地の下
から上に向って耕耘爪車が回転しながら掘り進むアップ
カット式のロータリ耕耘装置に用いられるものである。[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to agricultural machinery, and is applied to an up-cut rotary tiller that digs up cultivated land from the bottom to the top while the tilling wheel rotates. It is used.
〔従来技術と発明が解決しようとする問題点〕アップカ
ット式のロータリ耕耘装置は、耕耘爪車が掘り上げた土
を耕耘カバーの内面に沿わせて誘導して後方に放出する
が、その放出の際にツースでもって大きな塊やわら屑を
下方に導き、その上にツースの線杆の間を通った目の細
い土を載せるようにして仕上げるので１表面に細い土か
もられて平に仕上がシ、播種床に適する。[Problems to be solved by the prior art and the invention] In the up-cut type rotary tilling device, the tilling wheel guides the soil dug up along the inner surface of the tilling cover and releases it backward; During the process, the large lumps and straw waste are guided downward with the teeth, and then the fine soil that has passed between the wire rods of the teeth is placed on top of it, so the surface is finished evenly with a thin layer of soil. Suitable for seeding beds.
ここに−耕耘爪車を上下させて耕耘深度を変えると、こ
れにともなってツースの下端と地面との間隔も変るので
、耕耘深度が深いときにツースの先が地面に近すぎると
、負荷がかかり過ぎたり、逆に浅いときに地面から離れ
過ぎると、塊やわら屑がツースで充分に誘導されないで
表面が細く仕上がらない欠点がある。Here - when you change the tilling depth by moving the tilling wheel up and down, the distance between the bottom edge of the teeth and the ground will change accordingly, so if the tips of the teeth are too close to the ground when the tilling depth is deep, the load will increase. If it is too deep, or if it is too far from the ground when it is shallow, the teeth will not be able to sufficiently guide the lumps and straw debris, resulting in a poor surface finish.
この発明は、これらの欠点を、自動調節装置によって解
消するものである。The present invention overcomes these drawbacks by means of an automatic adjustment device.
このため、この発明においては、つぎの技術的手段を用
いた。Therefore, in this invention, the following technical means were used.
すなわち、耕地の下から上に向って回転しながら掘り進
む耕耘風車とこの耕耘風車の上方を被う耕耘カバーを備
え、耕耘風車の下端の深さを検出する検出手段と耕耘風
車の後方において耕耘カバーから地表に向って移動自在
に、突出されたツースを有し、このツースは上記の検出
手段の検出結果に基いてその深さが大のときには耕耘カ
バーからの突出量が小となり深さが小のときには突出量
が大となるように設けられていることを特徴とする耕耘
装置とする。That is, the tilling windmill is equipped with a tilling windmill that digs while rotating from the bottom to the top of the tilling windmill, a tilling cover that covers the top of the tilling windmill, a detection means for detecting the depth of the lower end of the tilling windmill, and a tilling cover behind the tilling windmill. It has protruding teeth that are movable toward the ground surface, and when the depth of the teeth is large based on the detection result of the above-mentioned detection means, the amount of protrusion from the tilling cover is small, and the depth is small. The tilling device is characterized in that the tilling device is provided so that the amount of protrusion becomes large when .
このため、耕耘風車の下端の地表からの深さすなわち耕
耘深度が犬となると、ツースの下端の耕耘カバーからの
突出量が小さくなって、ツースの下端は地表面からの適
正な間隔を保ち、逆に、耕耘深度が小となると、ツース
の下端は、これまでよりも余分に耕耘カバーから下方に
自動的に突出して、地面と適正な間隔を保つ。Therefore, when the depth of the lower end of the tilling windmill from the ground surface, that is, the tilling depth, becomes small, the amount of protrusion of the lower end of the tooth from the tilling cover becomes smaller, and the lower end of the tooth maintains an appropriate distance from the ground surface. Conversely, when the tilling depth becomes small, the lower ends of the teeth automatically protrude further downwards from the tilling cover than before to maintain an appropriate distance from the ground.
すなわち、この発明によると、耕耘深度の変動にかかわ
りなく、ツースの下端が自動的に地面と良好な間隔を保
つので、過負荷になったシ、仕上り不足になったシする
ことがなく、常に適正な耕耘作業が行なわれる特徴があ
る。In other words, according to this invention, the lower end of the tooth automatically maintains a good distance from the ground regardless of variations in the plowing depth, so there is no overload or insufficient finish, and the tiller can always be used. It is characterized by proper tillage work.
