水田等の畦形成においてトラクタに連結して側方に位置させた作業部の畦形成作業では、作業部はトラクタの側方後部にあるためトラクタが行き止まりになると作業部はその位置から前方の隅部は畦形成作業ができない。そのため残隅部の処理作業は、作業部をトラクタ進行方向に対して180°角水平方向に回動させ、更にトラクタも前後180°回転させて方向転換した後、トラクタを後進させて残隅部の作業処理を行っていた(従来技術1)。   In the paddle forming operation of the working part that is connected to the tractor and positioned laterally in paddy field formation such as paddy fields, the working part is located on the side rear side of the tractor. The part cannot perform ridge formation work. For this reason, the remaining corner portion is processed by rotating the working portion 180 ° in the horizontal direction with respect to the direction of travel of the tractor, and further rotating the tractor 180 ° forward and backward to change the direction, and then moving the tractor backward to move the remaining corner portion. (Conventional technology 1).

また、作業機が走行機の進行方向に対して側方にオフセットした位置で作業する作業機としては、以下のような公知例がある。特開2004−254522号公報(従来技術2)には、「オフセット作業方法」として、「走行機体にオフセット作業が行えるように装着された作業機による作業方法であって、作業機は、水平面内での回動及び移動の自由度を有し、作業機自体の直進性を維持しながら、走行機体が圃場を走行しつつ作業を行う作業部分から走行機体が旋回する圃場隅部分までの仕上げ作業を行う。作業機は、走行機体から見て少なくとも2以上の水平回動、あるいは水平移動と水平回動の自由度を有し、直進性を制御し、前作業跡を基準に作業を行う作業装置、作業機自身の回動変位量度を基準に行う作業装置などを備えている。」が開示されている。   Moreover, there are the following publicly known examples of working machines that work at positions where the working machine is offset laterally with respect to the traveling direction of the traveling machine. Japanese Patent Laid-Open No. 2004-254522 (Prior Art 2) discloses an “offset work method” as a work method using a work machine that is mounted on a traveling machine body so that an offset work can be performed. Finishing work from the work part where the traveling machine body works while traveling on the field to the corner part where the traveling machine body turns while maintaining the straightness of the work machine itself while having the freedom of rotation and movement The work machine has at least two or more horizontal rotations when viewed from the traveling machine body, or has a degree of freedom of horizontal movement and horizontal rotation, controls the straightness, and performs the work on the basis of the previous work mark. The apparatus includes a working device that is based on the degree of rotational displacement of the working machine itself. "

更に、特開2004−267012号公報(従来技術3)には、「オフセット作業機」として「作業部のオフセット位置を調整自在にしたオフセット位置調整機構と、作業部の作業方向を回動調整自在にした作業方向調整機構と、作業部と作業部によって作業がなされる基準作業線との位置関係を検出する検出部と、検出部からの検出信号に基づいて、オフセット位置調整機構を動作させて作業部のオフセット位置を調整すると共に作業方向調整機構を動作させて作業部の作業方向を調整する制御手段とを備え、作業部の作業位置と作業方向を基準作業線に沿うように制御する」作業機が開示されている。   Furthermore, in Japanese Patent Application Laid-Open No. 2004-267012 (Prior Art 3), as an “offset working machine”, an “offset position adjusting mechanism in which the offset position of the working unit is adjustable, and the working direction of the working unit can be freely adjusted.

And a control means for adjusting the work direction of the work part by adjusting the offset position of the work part and operating the work direction adjusting mechanism to control the work position and work direction of the work part so as to follow the reference work line. '' A work machine is disclosed.

更にまた、特開2004−275188号公報(従来技術4)には、「オフセット作業機」として、「オフセット作業機の一例である畦塗り機は、トラクタの後部に装着され、トラクタの走行に伴って進行してトラクタの走行位置に対して側方にオフセットした位置を作業する作業部を備え、少なくとも2以上の水平回動、又は、水平移動及び水平回動の自由度を有し、該自由度を制御するコントローラ(制御装置)を備える。作業部の自由度は作業者による手動操作によっても制御可能である。」との記載がある。   Furthermore, Japanese Patent Application Laid-Open No. 2004-275188 (prior art 4) states that, as an “offset working machine”, a “spreading machine, which is an example of an offset working machine, is mounted on the rear part of a tractor, and the tractor travels.

しかし、従来技術1のように水田等の圃場の作業残隅部の作業処理を行うために、トラクタ進行方向に対して作業部を180°角水平方向に回動させ、更にトラクタも前後180°回転させて方向転換した後、トラクタを後進させるという複数の面倒な作業を行なわなければならないという問題点があった。特に、トラクタを後進させて残隅部の作業処理を行う場合は、作業者は後方を見ながらトラクタの後進操作を行うため運転技術や作業などに熟練を要するという課題があり、誰でもが容易に作業を行い難いという課題があった。   However, as in the prior art 1, in order to carry out the work processing of the remaining work corners of the field such as paddy fields, the work part is rotated 180 ° horizontally with respect to the traveling direction of the tractor, and the tractor is also moved forward and backward 180 °. After turning and turning, there is a problem that a plurality of troublesome operations of moving the tractor backward has to be performed. In particular, when working on the remaining corners by moving the tractor backward, there is a problem that operators need to be skilled in driving techniques and work because they perform the reverse operation of the tractor while looking at the rear. There was a problem that it was difficult to work.

更に、従来技術2乃至5に係る作業機は、畦等の被作業面に対して作業部のオフセット位置を調整したり、作業部の作業方向を調整したりする制御手段を有する技術であるが、走行機、あるいは機枠(装着フレーム)と作業部との間の距離は一定しており、作業部を機枠に対して水平方向に回動させることにより、被作業面と作業部の間隔を調整する装置又は方法である。しかしながら従来技術2乃至5には走行機に対して畦形成機との異なる3つの作業姿勢に迅速かつ容易に対応できる制御方法や制御装置部の開示がなく、作業操作が複雑になる課題があった。   Furthermore, the working machines according to the related arts 2 to 5 are technologies that include a control unit that adjusts the offset position of the working unit with respect to a work surface such as a basket and adjusts the working direction of the working unit. The distance between the work surface and the working unit is fixed by rotating the working unit horizontally with respect to the machine frame. An apparatus or method for adjusting However, the prior arts 2 to 5 do not disclose a control method or a control unit that can quickly and easily correspond to three different working postures of the traveling machine with respect to the saddle forming machine, and there is a problem that the work operation becomes complicated. It was.

また、従来技術5の「圃場の隅まで連続的に畦塗り作業を行う畦塗り機及びその作業部位置調整方法」は、マーカを目視しながら畦等の被作業面に対して作業部の設置位置を操作するものであり、畦等の被作業面が直線でない場合や、草や樹木などの異物がある場合には、正確に作業が行えない課題があった。   In addition, “Plate coating machine that continuously coats the corners of the field and its working part position adjusting method” in the prior art 5 is the installation of the working part with respect to the work surface such as the tack while observing the marker. When the work surface such as a fence is not a straight line, or when there is a foreign object such as grass or a tree, there is a problem that the operation cannot be performed accurately.

請求項1に係る発明は、走行機に連結され、装着フレームと、畦形成部と、装着フレームと畦形成部とを連結する連結部と、制御部と、操作部とを有する畦形成機であり、連結部は、装着フレームに設けられる連結部回動支点を中心に水平方向に回動可能であり、装着フレームと畦形成部間との間の距離を伸縮可能にするアクチュエーターを設け、制御部は、走行機が略直線状に前進して走行機と平行な直線状の畦形成作業をする第1の場合と、走行機が旋回しながら直線状に畦形成作業をする第2の場合とに、畦形成機の状態を切換え可能であり、第2の場合に、制御部が、連結部の連結部回動支点での回動変位量の情報を基に、あらかじめ設定されたプログラムにより回動変位量に対応してアクチュエーターを連続的に制御して装着フレームと畦形成部間の距離を変更させ、走行機が旋回移動するのに対し畦形成部が連続して直線状に移動しつつ畦形成作業を行わせることを特徴とする。The invention according to claim 1 is a scissor forming machine that is connected to a traveling machine and has a mounting frame, a scissor forming part, a connecting part that connects the mounting frame and the scissor forming part, a control part, and an operating part. Yes, the connecting part can be horizontally rotated around the connecting part rotation fulcrum provided on the mounting frame, and an actuator is provided to control the distance between the mounting frame and the heel forming part, and control is provided. In the first case where the traveling machine advances in a substantially straight line and performs a linear ridge forming work parallel to the traveling machine, and the second case in which the traveling machine performs a linear ridge forming work while turning. In addition, in the second case, the state of the wrinkle forming machine can be switched, and in the second case, the control unit uses a preset program based on the information of the rotational displacement at the connecting portion rotating fulcrum of the connecting portion. The actuator is continuously controlled in accordance with the amount of rotational displacement, so To change the distance between the beam and the ridge forming portion, the traveling machine, characterized in that to perform the ridge forming operation while moving in a straight line ridge forming portion continuously while pivoting movement.

請求項2に係る発明は、請求項1記載の畦形成機であって、制御部は、畦形成機の作業状態を、走行機を停止させて走行機の後方に畦形成部を位置させて走行機の進行方向と直交する方向へ畦形成作業をする第3の場合にも切換え可能であり、第3の場合に、制御部が、連結部の連結部回動支点での回動変位量の情報を基に、あらかじめ設定されたプログラムにより回動変位量に対応してアクチュエーターを連続的に制御して装着フレームと畦形成部間の距離を変更させるとともに、連結部に設けられ畦形成部を水平方向に回動可能にする畦形成部回動支点の回動変位量を制御して連結部に対して畦形成部を回動させ、停止している走行機の進行方向と直交する直線状方向に畦形成部を移動させつつ畦形成作業を行わせることを特徴とする。The invention according to claim 2 is the scissor forming machine according to claim 1, wherein the control unit stops the traveling machine and positions the scissor forming part at the rear of the traveling machine. Switching is also possible in the third case where the saddle forming operation is performed in a direction orthogonal to the traveling direction of the traveling machine. In the third case, the control unit rotates the amount of rotation at the connecting portion rotation fulcrum of the connecting portion. Based on this information, the actuator is continuously controlled according to the rotational displacement amount by a preset program to change the distance between the mounting frame and the heel forming portion, and the heel forming portion provided in the connecting portion A straight line that is orthogonal to the traveling direction of the traveling machine that is stopped by controlling the amount of rotational displacement of the pivoting fulcrum of the collar-forming part that rotates the collar in the horizontal direction and pivoting the collar-forming part relative to the connecting part. The wrinkle forming operation is performed while moving the wrinkle forming portion in the shape direction.

この発明によれば、畦形成機の制御部が、走行機が略直線状に前進して畦形成作業する場合と、走行機が旋回しながら直線状に畦形成作業する場合とに、それぞれ対応して切換え可能であることにより、通常の走行機が略直線状に前進して畦形成作業する場合の他に、圃場隅部で走行機が旋回しながら作業する場合は、それに対応して切換えられた制御部により走行機が旋回移動するのに対し畦形成部は直線状に移動しつつ畦形成作業を行わせることが可能になった。したがって制御部の切り換え操作のみで予め入力されているプログラムにしたがって直線状畦の形成が圃場隅部の角隅まで未作業の畦部分がなく容易に形成することができる。   According to the present invention, the control unit of the kite forming machine corresponds to the case where the traveling machine moves forward substantially linearly and performs the kite forming work, and the case where the traveling machine performs the kite forming work linearly while turning. In addition to the case where a normal traveling machine moves forward in a substantially straight line and performs ridge formation work, when the traveling machine turns while working at the corner of the field, switching is performed accordingly. While the traveling machine swivels and moves by the control unit, the hook forming section can perform the hook forming work while moving linearly. Therefore, according to the program inputted in advance only by the switching operation of the control unit, the formation of the straight ridge can be easily formed without the unworked ridge portion to the corner of the field corner.

更に請求項2に係る発明によれば、制御部が、走行機が略直線状に前進して畦形成作業する場合と、走行機が旋回しながら圃場隅部分を直線状に畦形成作業する場合と、走行機を停止させて走行機の後方に畦形成部を位置させて走行機の進行方向と直交する方向へ畦形成作業する場合とに、それぞれ対応して切換え可能であることにより、通常の走行機が略直線状に前進して畦形成作業する場合の他に、圃場隅部で走行機が旋回しながら作業する場合は、それに対応して切換えられた制御部により走行機が旋回移動するのに対し畦形成部は直線状に移動しつつ畦形成作業を行わせること及び走行機を停止させて走行機の後方に畦形成部を位置させて走行機の進行方向と直交する方向へ畦形成作業する場合は、停止している走行機進行方向と直行する直線状方向に畦形成部は移動しつつ畦形成作業を行わせることが可能になった。走行機を停止させて作業を行うため圃場隅部の未作業部分を確実になくすことができる。   Furthermore, according to the invention which concerns on Claim 2, a control part is a case where a traveling machine advances a substantially linear shape, and when a traveling machine turns, and a traveling machine turns a field corner part linearly while forming a straw And when the hook is formed in the direction perpendicular to the traveling direction of the traveling machine by stopping the traveling machine and positioning the hook forming part behind the traveling machine, In addition to the case where the traveling machine moves forward in a substantially straight line to perform ridge formation work, when the traveling machine turns while working in the corner of the field, the traveling machine turns and moves by the control unit switched correspondingly. On the other hand, the kite forming part moves the kite while moving linearly, stops the traveling machine and positions the kite forming part behind the traveling machine in a direction orthogonal to the traveling direction of the traveling machine. When carrying out ridge formation work, Ridge forming portion linearly direction became possible to perform the ridge forming operation while moving. Since the operation is performed with the traveling machine stopped, the unworked portion at the corner of the field can be reliably eliminated.

The ridge forming machine A is connected to the traveling machine B to perform work. C is a field corner and D is a basket.

畦形成機Aは、走行機Bが略直線状に前進して直線状畦形成作業する場合には、操作部5により制御部4をそれに対応するプログラムに切り換えて行う。この場合は、図1及び図3に示すように畦形成機Aは姿勢をほぼ固定され走行機Bと平行な位置で走行機Bに従って一定移動を行い直線状畦Dを形成する。 When the traveling machine B moves forward in a substantially straight line and performs a straight wrinkle forming operation, the wrinkle forming machine A switches the control unit 4 to a program corresponding to the operation unit 5. In this case, as shown in FIGS. 1 and 3, the saddle- forming machine A is substantially fixed in posture and moves in a constant manner in accordance with the traveling machine B at a position parallel to the traveling machine B to form a linear saddle D.

畦形成機Aは、図4及び図5に示すように走行機Bが旋回しながら圃場隅部分Cを直線状に畦形成作業する場合は、操作部5により制御部4をそれに対応するプログラムに切り換えて行う。この場合は、制御部4は、装着フレーム1に設けた連結部2の回動支点の回動変位量の情報を検知する連結部回動変位量検知センサー28からの検知信号を基にあらかじめ設定されたプログラムにより連結部伸縮シリンダ26の長さを連続的に制御して、装着フレーム1と畦形成部3間の長さを連続的に変更させる。これにより走行機Bが旋回移動するのに対し畦形成部3は直線状に移動しつつ圃場隅部分Cを隅まで直線で畦形成作業を行わせることができる。   As shown in FIGS. 4 and 5, when the traveling machine B turns and the ridge forming machine A linearly forms the ridge forming operation on the field corner portion C, the operation unit 5 sets the control unit 4 to a program corresponding thereto.

In this case, the control unit 4 is set in advance based on a detection signal from the connecting portion rotational displacement detection sensor 28 that detects information about the rotational displacement of the rotational fulcrum of the connecting portion 2 provided on the mounting frame 1. The length of the connecting part telescopic cylinder 26 is continuously controlled by the programmed program, and the length between the mounting frame 1 and the heel forming part 3 is continuously changed. As a result, while the traveling machine B turns and moves, the ridge forming section 3 can perform the ridge forming operation in a straight line from the field corner portion C to the corner while moving linearly.

畦形成機Aは、図6に示すように走行機Bを停止させて走行機Bの後方に畦形成部3を位置させて走行機Bの進行方向と直交する方向へ畦形成部3を移動させて畦形成作業する場合は、操作部5により制御部4をそれに対応するプログラムに切り換えて行う。切換えられた制御部4は、畦形成部3の作業面Dが一定の直線状畦になるように予め設定されているプログラムにより連結部回動シリンダ27、連結部伸縮シリンダ26、畦形成部回動シリンダー30のそれぞれに指示信号を送信する。そして、装着フレーム1に対する連結部2の回動支点の回動変位量の情報を基に、あらかじめ設定されたプログラムにより連結部2の回動支点の回動変位量に対応して連結部伸縮シリンダ26の長さを連続的に制御して装着フレーム1と畦形成部3間の距離を変更させるとともに、畦形成部回動シリンダー30を作動させ連結部2に設けた畦形成部3の回動支点の回動変位量を制御し、畦形成部3を畦形成部回動軸32を中心に連結部2の回動方向とは逆方向に適宜回動させて行う。   As shown in FIG. 6, the kite forming machine A stops the traveling machine B, positions the kite forming part 3 behind the running machine B, and moves the kite forming part 3 in a direction perpendicular to the traveling direction of the running machine B. In the case where the wrinkle forming work is performed, the operation unit 5 switches the control unit 4 to a corresponding program. The switched control unit 4 is connected to the connecting part rotating cylinder 27, the connecting part expansion / contraction cylinder 26, the hook forming part rotation by a program set in advance so that the work surface D of the hook forming part 3 becomes a constant linear hook. An instruction signal is transmitted to each of the moving cylinders 30. Then, based on the information of the rotational displacement of the rotational fulcrum of the connecting part 2 with respect to the mounting frame 1, the connecting part telescopic cylinder corresponds to the rotational displacement of the rotational fulcrum of the connecting part 2 by a preset program. The length of 26 is continuously controlled to change the distance between the mounting frame 1 and the heel forming portion 3, and the heel forming portion rotating cylinder 30 is operated to rotate the heel forming portion 3 provided in the connecting portion 2. The amount of pivotal displacement of the fulcrum is controlled, and the hook forming portion 3 is appropriately rotated around the hook forming portion rotating shaft 32 in the direction opposite to the rotating direction of the connecting portion 2.
