図7および図8に示すように、一の畦aと他の畦bとが角位置Pで直角に交わる圃場の隅部において、トラクタ2がトラクタラインCを描くように前進走行しながら左方向に向って旋回する場合、作業機本体3の作業部5は、制御手段が伸縮手段(回動シリンダ)4およびオフセットシリンダ10を制御することにより、伸縮手段4およびオフセットシリンダ10の伸縮に基づいて、圃場の隅部の角位置Pの近傍を伸縮円弧状軌跡Aを描くように円弧状に移動する。   As shown in FIG. 7 and FIG. 8, at the corner of the field where one heel a and the other heel b intersect at a right angle at the angular position P, the tractor 2 travels forward so as to draw the tractor line C while moving in the left direction. , The working unit 5 of the work implement body 3 is controlled based on the expansion / contraction of the expansion / contraction means 4 and the offset cylinder 10 by the control means controlling the expansion / contraction means (rotating cylinder) 4 and the offset cylinder 10. In the vicinity of the angular position P at the corner of the farm field, it moves in an arc shape so as to draw a telescopic arc-shaped locus A.

このトラクタ2の前進旋回時には、伸縮手段4およびオフセットシリンダ10が徐々に伸び、作業部5の畦形成体77が畦a,bと略45°の角度で交わる線D上に位置したときに、伸縮手段4およびオフセットシリンダ10が最も伸びた状態になり、その後、伸縮手段4およびオフセットシリンダ10が徐々に縮み、その結果、作業部5が圃場の隅部の角位置Pの近傍を伸縮円弧状軌跡Aを描くように円弧状に移動する。   When the tractor 2 is turned forward, the expansion / contraction means 4 and the offset cylinder 10 are gradually extended, and when the rod forming body 77 of the working unit 5 is positioned on a line D that intersects with the rods a and b at an angle of approximately 45 °, The expansion / contraction means 4 and the offset cylinder 10 are in the most extended state, and then the expansion / contraction means 4 and the offset cylinder 10 are gradually contracted. As a result, the working unit 5 extends and contracts in the vicinity of the angular position P at the corner of the field. It moves in an arc shape so as to draw a locus A.

また、一の畦aの終端部と他の畦bの始端部とには長さL1の未作業部分が生じるものの、トラクタ本体11の3点リンクヒッチ部14で作業機本体3を昇降させることなく、直角に交わる一の畦aおよび他の畦bに対して連続的に畦塗り作業が可能である。   Moreover, although the unfinished part of length L1 arises in the termination | terminus part of one hail | claw a, and the start end part of the other hail | bowl b, the working machine main body 3 is raised / lowered by the three-point link hitch part 14 of the tractor main body 11. In other words, it is possible to continuously perform the glazing operation on one ridge a and another ridge b that intersect at right angles.

そして、このような農作業機1によれば、圃場の隅部においてトラクタ2のバック走行が不要で、効率よくオフセット作業である畦塗り作業ができ、しかも、圃場の隅部での未作業部分の長さをできる限り短くでき、未作業部分に対する人力作業負担の軽減を図ることができる。   And according to such a farming machine 1, the back travel of the tractor 2 is unnecessary in the corner part of a farm field, the haze coating work which is an offset work can be performed efficiently, and the unworked part in the corner part of a farm field can be performed. The length can be shortened as much as possible, and the burden of manpower work on unworked parts can be reduced.

また、伸縮手段4が縮んだ状態時に伸縮手段4の縮み動作によりロック解除状態からロック状態になってトラクタ2に対する作業機本体3の回動を規制し、伸縮手段4が伸びた状態時に伸縮手段4の伸び動作によりロック状態からロック解除状態になってトラクタ2に対する作業機本体3の回動を許容するロック手段65を備えるため、伸縮手段4が縮んだ状態時に作業機本体3が不用意に回動するのを防止できるとともに、伸縮手段4への負荷を軽減できる。   Further, when the expansion / contraction means 4 is contracted, the contraction operation of the expansion / contraction means 4 changes from the unlocked state to the locked state to restrict the rotation of the work machine body 3 relative to the tractor 2, and when the expansion / contraction means 4 is extended, the expansion / contraction means 4 is provided with a lock means 65 that changes the locked state from the locked state to the unlocked state by the extension operation of 4 and allows the work machine body 3 to rotate with respect to the tractor 2. While being able to prevent rotation, the load on the expansion / contraction means 4 can be reduced.

なお、上記実施の形態では、図1等に示すように、伸縮手段4が作業機本体3のトラクタ連結部43の片方のロワアーム47に設けられた構成について説明したが、例えば図9に示すように、伸縮手段4をトラクタ2の3点リンクヒッチ部14の片方のロワリンク16に設けて、その伸縮手段4の伸縮作動により作業機本体3がトラクタ2のトラクタ本体11に対して上下方向の回動中心軸線(回動支点)Xを中心として回動するようにしてもよい。   In the above-described embodiment, as shown in FIG. 1 and the like, the configuration in which the expansion / contraction means 4 is provided on one lower arm 47 of the tractor connecting portion 43 of the work machine body 3 has been described. For example, as shown in FIG. Further, the expansion / contraction means 4 is provided on one lower link 16 of the three-point link hitch portion 14 of the tractor 2, and the work implement main body 3 rotates in the vertical direction with respect to the tractor main body 11 of the tractor 2 by the expansion / contraction operation of the expansion / contraction means 4. You may make it rotate centering | focusing on the dynamic center axis line (rotation fulcrum) X. FIG.

また、例えば図10に示すように、伸縮手段4を第1伸縮部4aと第2伸縮部4bとで構成し、第1伸縮部4aをトラクタ2の3点リンクヒッチ部14の片方のロワリンク16に設けかつ第2伸縮部4bを作業機本体3のトラクタ連結部43の片方のロワアーム47に設けて、これら第1伸縮部4aおよび第2伸縮部4bの伸縮により作業機本体3がトラクタ2のトラクタ本体11に対して上下方向の回動中心軸線(回動支点)Xを中心として回動するようにしてもよい。なお、いずれの場合も、回動駆動手段である伸縮手段4の作動に基づくトラクタ2に対する作業機本体3の回動角度αは、例えば5°〜20°、好ましくは略10°である。   For example, as shown in FIG. 10, the expansion / contraction means 4 is composed of a first expansion / contraction part 4a and a second expansion / contraction part 4b, and the first expansion / contraction part 4a is composed of one lower link 16 of the three-point link hitch part 14 of the tractor 2. And the second telescopic portion 4b is provided on one lower arm 47 of the tractor connecting portion 43 of the work implement body 3, and the work implement main body 3 is attached to the tractor 2 by the expansion and contraction of the first telescopic portion 4a and the second telescopic portion 4b. You may make it rotate with respect to the tractor main body 11 centering on the rotation center axis line (rotation fulcrum) X of an up-down direction. In any case, the rotation angle α of the work implement body 3 with respect to the tractor 2 based on the operation of the expansion / contraction means 4 serving as the rotation drive means is, for example, 5 ° to 20 °, preferably about 10 °.

さらに、図示しないが、伸縮手段4をカプラ21と作業機本体3のトラクタ連結部43との間に設けたり、伸縮手段4をトラクタ2の3点リンクヒッチ部14とカプラ21との間に設けたりしてもよい。   Further, although not shown, the expansion / contraction means 4 is provided between the coupler 21 and the tractor connecting portion 43 of the work machine body 3, or the expansion / contraction means 4 is provided between the three-point link hitch portion 14 of the tractor 2 and the coupler 21. Or you may.

また、回動駆動手段は、電動油圧シリンダ等からなる伸縮手段4には限定されず、例えば図11および図12に示すように、ラック91およびピニオン92を用いたものでもよい。この図11および図12に示す構成では、片方のロワアーム47が伸縮可能、つまり第1アーム47aに対して第2アーム47bが移動可能となっており、その第2アーム47bにラック91が固着され、そのラック91にピニオン92が係合している。そして、ピニオン92は駆動源であるモータ93の出力軸に固着されており、このモータ93の作動でピニオン92が回転し、このピニオン92の回転に基いて第2アーム47bが第1アーム47aに対して移動し、その結果、作業機本体3をトラクタ2に対して上下方向の回動中心軸線(回動支点)Xを中心として回動する。   Further, the rotation driving means is not limited to the expansion / contraction means 4 made of an electrohydraulic cylinder or the like. For example, as shown in FIGS. 11 and 12, a rack 91 and a pinion 92 may be used. In the configuration shown in FIGS. 11 and 12, one lower arm 47 can be expanded and contracted, that is, the second arm 47b can move with respect to the first arm 47a, and the rack 91 is fixed to the second arm 47b. The pinion 92 is engaged with the rack 91. The pinion 92 is fixed to the output shaft of the motor 93 that is a drive source. The pinion 92 is rotated by the operation of the motor 93, and the second arm 47b is moved to the first arm 47a based on the rotation of the pinion 92. As a result, the work implement main body 3 is rotated with respect to the tractor 2 about a rotation center axis (rotation fulcrum) X in the vertical direction.

なお、オフセット作業である畦塗り作業をする畦塗り機以外に、オフセット作業である溝掘作業する溝掘機等にも適用可能である。   The present invention can also be applied to a grooving machine that performs a grooving operation that is an offset operation, in addition to a glazing machine that performs a lacquering operation that is an offset operation.
