Therefore, the remaining corner corner forming operation is performed by rotating the flange forming operation portion 180 ° in the horizontal direction with respect to the traveling direction of the tractor, and further rotating the tractor 180 ° forward and backward to change the direction, and then moving the tractor backward. In other words, the remaining corners were subjected to the ridge forming work (prior art 1).

  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. The finishing work from the work part where the traveling machine body works while traveling on the field to the corner part of the field where the traveling machine body turns while maintaining the straightness of the work machine itself. The working machine has at least two or more horizontal rotations as viewed from the traveling machine body, or has a degree of freedom of horizontal movement and horizontal rotation, and controls the straightness and performs the work on the basis of the previous work mark. , A work device that is based on the work trace of the work machine itself, a work device that is based on the rotation angle of the work machine itself, and the like are disclosed.

  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. The offset adjustment mechanism is operated based on a detection signal from the detection unit, a detection unit that detects a positional relationship between the work direction adjustment mechanism that has been made, a work unit and a reference work line on which the work unit performs work. 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.

  Japanese Patent Laying-Open No. 2005-46040 (Prior Art 4) discloses a “cooking machine that continuously coats a corner of a field and a method for adjusting the position of the working unit”. The wrinkle coating machine of the prior art 4 has “a work part position adjusting device 61 that can install the work part 30 along one side Fa of the old carp, and the work part position adjusting device 61 has a rear end of the offset frame 10. The first marker 62 that allows visual confirmation from the traveling machine body whether or not the working unit 30 that is rotatably provided in the unit is installed at the installation position of the old saddle, and the direction of the working unit 30 is substantially parallel to one side Fa. The second marker 64 that can be visually checked from the traveling body, the actuator that can operate the turning cylinder 13 that turns the offset frame 10 and the turning cylinder 57 that turns the working unit 30.

  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.

  Furthermore, the working machines according to the related arts 2 to 4 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 saddle 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, in the related arts 2 to 5, there is a problem that when the traveling machine starts to turn at the corner of the field, there is no member or device for ensuring the straightness of the straw molding machine, and the straightness is not stable.

  Further, the prior art 5 states that “the offset arm 5 is rotated in the horizontal direction around the pivot A and the working unit 51 pivotally supported at the tip of the offset arm 5 can be moved left and right from the tractor 2 [ “Pivot part A”, “Column 0047 of Patent Document 4”, and “Pivot part B composed of a horizontal rotation shaft 54 that extends in the vertical direction by horizontally rotating the support / transmission frame 7”. The traveling machine (main body frame 4) and the working unit 51 are connected to each other. Therefore, when the traveling machine starts to rotate in the corners of the field, as shown in FIG. 2 of Patent Document 4, the rotation directions of the two pivot portions A and the pivot directions of the pivot portions B are reversed. There was a problem that the pressure in the heel direction of the working unit 51 connected through the two pivots A and B is very small.

  Therefore, in the prior art 5, since the molding pressure in the cocoon direction at the corner of the field is reduced, there is a problem that it is easy to be affected by the soil quality of the field and a solid cocoon cannot be formed.

In order to solve the above-mentioned problem, in a scissor forming machine that includes a scissor forming work part having a mounting frame, a banking part and a growth part, and is attached to a traveling machine such as a tractor,

  Further, the horizontal turning means of the cocoon forming work part can rotate and fix the cocoon forming work part to an arbitrary position, and the wing forming work part can be freely rotated. A wrinkle forming machine described in the column 0012, which is a horizontal rotation means of the wrinkle forming working unit capable of the above, is proposed.

  In addition, the horizontal movement means of the cocoon forming work part can move the cocoon forming work part to an arbitrary position and hold it in a fixed manner, and can also be in a movement-free state in which the cocoon forming work part can move freely. A wrinkle forming machine described in the 0012 column or the 0013 column, which is a horizontal moving means of the wrinkle forming working unit, is proposed.

  Furthermore, the horizontal turning means of the cocoon forming work section and the horizontal movement means of the cocoon forming work section are controlled by a control unit that can be remotely operated from the driver's seat of the traveling machine of the cocoon forming machine, and the control unit is a traveling machine.畦, 0013 or 0014, which is a control unit having a work mode when the vehicle travels parallel to the kite and a direction change mode when the traveling machine travels away from the kite Propose a machine.

  In addition, by providing a front guide wheel and a rear guide wheel having a plate-like surface, the front guide wheel stabilizes resistance and vibration generated by excavation of the rotor (excavation claw) of the embankment portion, and straight ahead in the traveling direction To stabilize. This straightness is stable because the guide wheels are provided at intervals in the front-rear direction, and can also receive the reaction force received by the scissors forming working part from the scissors that are formed at the time of scissors formation. In addition, since the front guide wheel and the rear guide wheel are provided, there is an effect that a hard cocoon can be formed in order to receive the reaction force from the cocoon and prevent the cocoon forming work part from escaping to the field side.

  Further, according to the present invention, the support frame is provided to be fixed obliquely rearward, and the hook forming work part is provided on the support frame so as to be movable. Because it is possible, when controlling the attitude of the saddle forming work part corresponding to the change of the traveling direction due to the change of the course of the traveling machine, it is possible to adjust the offset amount and the position in the front-rear direction only by the perspective movement, Easy programming of the controller.
