Description

本発明に係るロータリ耕耘装置の第１特徴構成は、両端部が後方に折れ曲がる可撓性を有し、且つその上端部がロータリ耕耘装置のカバーの後端部分に連結されている平板と、前記平板の下辺部の横方向中央部に接触して該横方向中央部が前記カバーの後方に移動するのを規制する規制状態、及び前記横方向中央部が前記カバーの後方へ移動するのを許容する解除状態に切換自在な規制部材と、耕耘地を平らにならすための硬質の整地板とを備え、前記整地板を前記平板の後方に配置し、該平板及び該整地板が前記カバーの後端部分を支点として上下に揺動可能であり、前記整地板を前記平板から後方又は上方に離れた姿勢に保持可能な手段を備える点にある。 The first characteristic configuration of the rotary tiller according to the present invention is a flat plate in which both end portions are flexible to bend backward and the upper end portion is connected to the rear end portion of the cover of the rotary tiller device, Restricted state in which the lateral center of the flat plate contacts the lateral center of the lower side and restricts the lateral central from moving to the rear of the cover, and the lateral central is allowed to move to the rear of the cover A regulating member that can be switched to a released state and a hard leveling plate for leveling the cultivated land, and the leveling plate is disposed behind the flat plate, and the flat plate and the leveling plate are disposed behind the cover. It is possible to swing up and down with an end portion as a fulcrum, and to include means for holding the ground leveling plate in a posture separated rearward or upward from the flat plate.

〔作用及び効果〕
本構成のごとく、硬質の整地板が平板の後方に配置され、平板及び整地板がカバーの後端部分を支点として上下に揺動可能であれば、規制部材を解除状態として、整地板を下方に揺動させてカバーの後端部分から垂れ下がる姿勢とすることによって、平板と整地板とが一体となった状態で上下に揺動することになり、均平作業を実施することができる。このとき平板が前方で整地板が後方に位置するため、ほとんど整地板が機能することによって、耕耘地が均平にならされる。また、耕耘爪によって跳ね上げられた耕耘土が前方の平板に当たり易く、後方の整地板には当たり難いため、整地板が破損し難い。
さらに、本構成のごとく、整地板を平板から後方又は上方に離れた姿勢に保持可能な手
段を備えるものであれば、規制部材を規制状態として、整地板を平板から後方又は上方に離れた姿勢に保持することによって、整地板が畝立て形成の邪魔にならず、平板によって効率良く畝を形成することができる。
従って、本構成によれば、畝立て作業及び均平作業を実施する際に、平板の装着又は取り外しを行う必要がなく作業性が良い。 [Action and effect]
As in this configuration, if the hard leveling plate is placed behind the flat plate and the flat plate and leveling plate can swing up and down with the rear end of the cover as a fulcrum, the regulating member is released and the leveling plate is lowered By swinging to a position that hangs down from the rear end portion of the cover, the flat plate and the leveling plate are swung up and down so that leveling can be performed. At this time, since the flat plate is in front and the leveling plate is located in the rear, the leveling plate functions almost so that the cultivated land is leveled. Moreover, since the cultivated soil flipped up by the cultivating claws is likely to hit the front flat plate and is difficult to hit the rear leveling plate, the leveling plate is not easily damaged .
Further, as in this configuration, if it is provided with means capable of holding the leveling plate in a posture away from the flat plate in the rear or upward direction, the regulating member is in the restricted state and the leveling plate is separated from the flat plate in the rear or upward direction. The leveling plate does not obstruct the formation of ridges, and the ridges can be efficiently formed by the flat plates.
Therefore, according to this configuration, when performing the uprighting work and the leveling work, it is not necessary to attach or remove the flat plate, and the workability is good.

第２特徴構成は、前記平板は、その全体が可撓性を有する平板で構成されている点にある。
〔作用効果〕
本特徴構成によれば、規制部材を解除状態として、整地板を下方に揺動させてカバーの後端部分から垂れ下がる姿勢とすることによって、平板に耕耘土が当たった場合でも、平板が少し弾性変形し得るため、耕耘土が平板に付着し難い。 The second characteristic configuration is that the flat plate is formed of a flexible flat plate as a whole.
[Function and effect]
According to this characteristic configuration, the flat plate is slightly elastic even when the flat soil hits the flat plate by swinging the leveling plate downward and hanging from the rear end portion of the cover with the regulating member in the released state. Since it can be deformed, it is difficult for the cultivated soil to adhere to the flat plate.

第３特徴構成は、前記平板及び前記整地板が、同じ又は略同じ大きさの横長形状を有する点にある。
〔作用及び効果〕
本構成によれば、均平作業時において、平板の後方に位置する整地板によって平板のばたつきをより確実に抑えることができる。さらに、耕耘爪に対して、整地板が平板の後方に隠れる状態となるため、耕耘爪によって跳ね上げられた耕耘土が、整地板に対して一層当たり難い。 A third characteristic configuration is that the flat plate and the leveling plate have a horizontally long shape having the same or substantially the same size.
[Action and effect]
According to this configuration, flapping of the flat plate can be more reliably suppressed by the leveling plate located behind the flat plate during the leveling operation. Furthermore, since the leveling plate is hidden behind the flat plate with respect to the tilling claw, the tilled soil jumped up by the tilling claw is more difficult to hit the leveling plate.

第４特徴構成は、前記整地板に連結部を設け、前記平板に被連結部を設けて、該連結部と該被連結部との連結によって、前記平板と前記整地板との間に隙間が設けられた状態で、該平板と該整地板とが解除可能に連結される点にある。 In the fourth feature configuration, a connecting portion is provided on the leveling plate, a connected portion is provided on the flat plate, and a gap is formed between the flat plate and the leveling plate by connecting the connecting portion and the connected portion. In this state, the flat plate and the leveling plate are releasably connected.

機体の前進に伴って、正逆転爪１０の正転方向（図３の矢印Ａ１の方向）の回転駆動によって耕起された土が平板１８により受け止められるが、平板１８に設けた金属板２７の下辺部分２７ｂがカバー１１の後方に移動せず、平板１８の左右の横側部が後方に移動することになる。
As the machine moves forward, the soil cultivated by the forward rotation of the forward / reverse claw 10 (direction of arrow A1 in FIG. 3 ) is received by the flat plate 18, but the metal plate 27 provided on the flat plate 18 The lower side portion 27b does not move rearward of the cover 11, and the left and right lateral sides of the flat plate 18 move rearward.
