Utility Model Registration No. 2540481 JP 2004-187580 A Japanese Patent Laying-Open No. 2005-058202

  In the prior arts 1 to 3, a support frame that rotates or turns 180 degrees in the horizontal direction is attached to a machine frame or a mounting frame that is a part that is directly attached to a tractor, and a hook forming portion is attached to the rotating end of the support frame. A wrinkle forming apparatus is disclosed. Therefore, the wrinkle forming device is fixed and attached to the tractor in a fixed posture. However, when the heel forming device is mounted by their machine frame or mounting frame due to the difference in the tractor model, the horizontal rotation axis of the heel forming portion cannot be mounted so that it is always vertical. There was a problem that the work was complicated.

  For example, FIG. 9 and FIG. 10 show a conventional wrinkle forming apparatus, and FIG. 9 shows a wrinkle forming apparatus A mounted on a tractor in a state where a rotation center axis 100a for rotating a wrinkle forming working unit is vertical. However, FIG. 10 shows the rod forming apparatus B mounted on the tractor in a state in which the rotation center shaft 100b for rotating the rod forming working portion is obliquely deviated from the vertical. In the state shown in FIG. 10, the heel forming apparatus B attached to the tractor is rotated by 180 degrees from the left side of the tractor to the right side of the tractor, so that the front and back of the heel forming work part change. The heights of the ridge forming unit 101 and the embankment device 102 are reversed, and it is necessary to adjust the height each time, which is troublesome.

In order to solve the above problems, a mounting frame coupled to the tractor, a working unit support frame coupled to the mounting frame so as to be rotatable in the vertical direction, and a first rotation center provided on the working unit support frame are provided. A pivot frame that is pivotable in a horizontal direction and can be expanded and contracted at the center, a hook-forming work section that is provided on the pivot end side of the pivot frame and is pivotable in a horizontal direction with respect to the work section support frame, and a work section A rotating rod that rotates between a support frame and a rotating frame and that rotates in a horizontal direction around a second rotating center portion located on the tractor side from a first rotating center portion provided on the working unit support frame; Have

  In addition, a wrinkle forming machine described in the column 0008 or 0009 is provided in which a rotation position fixing means is provided in the vicinity of the rotation center of the younger brother 1 which is the rotation center of the rotation frame.

  Moreover, the wrinkle forming machine according to 0008, 0009, or 0010 is proposed in which the rotating rod is a rotating rod whose length can be changed.

  Since this is a double frame, a mounting frame that is directly mounted on the tractor and a working part support frame that is pivotably connected to the mounting frame in the vertical direction, even if the mounting posture of each individual tractor is different, Only the working unit support frame provided with the moving frame can be easily adjusted in the vertical direction. For this reason, the rotation axis of the first rotation center that is the rotation center of the rotation frame can be easily adjusted so as to be substantially vertical. If it is configured to be in the vertical position, it is not necessary to readjust the height adjustment between the embankment device and the ridge forming device even when the ridge forming operation portion is rotated to the forward operation position or the reverse operation position. .

  The scissor forming working portion provided on the rotating end side of the rotating frame rotates according to the rotation trajectory of a rotating rod that rotates in the horizontal direction around the second rotating central portion, thereby Is set to the non-working position as in the tractor rear position (see FIG. 5), the dredging work portion is closer to the tractor side than in the prior art, so the weight balance during traveling is good.

  Since the outer frame is formed or fixed integrally with the flange forming work part and does not have the rotation adjusting part, the structure can be simplified and the manufacturing cost can be reduced.

  The rotation rod is a rotation rod whose length can be changed, so that the offset from the tractor when the rod forming work part is rotated to the forward work position, the reverse work position, and the non-work position during movement. The amount can be easily adjusted.

  The fixed plate 70 is an arc-shaped plate-like body, and has a plurality of engagement holes 700 at positions approximately 90 degrees apart. The fixing plate 70 rotates together with the rotation of the rotation frame 3 and engages with the lock pin 71 so that the rotation frame 3 cannot be rotated and is fixed. In this embodiment, the saddle-forming work unit 4 that rotates together with the rotating frame 3 is located at either the forward operation position (for example, the tractor right side), the reverse operation position (for example, the tractor left side), or the movement position (the tractor rear side). When it comes, the lock pin 71 is engaged with the engagement hole 700 to disable the rotation of the rotation frame 3.

  In the engagement between the lock pin 71 and the engagement hole 700 of the fixing plate 70, the wire cable 73 is operated by the operation handle 74 to rotate the link lot 72 and move the lock pin 71 up and down.

  Next, the operation of the wrinkle forming machine according to the present invention will be described. In the wrinkle forming machine according to the present invention, the mounting portion to the tractor is composed of a double frame of the mounting frame 1 and the working portion support frame 2 and can be rotated in the vertical direction. Therefore, the position of the mounting frame 1 fixed to various tractors On the other hand, the working part support frame 2 can be rotated in the vertical direction.

  The working unit support frame 2 is pivoted in the vertical direction by rotating the handle 122 and extending the telescopic rod 12 so that the working unit support frame 2 is lowered with respect to the mounting frame 1 around the pivot coupling shaft 11. It can be rotated.

  By rotating the handle 122 in the reverse direction and shortening the telescopic rod 12, the working unit support frame 2 can be rotated upward with respect to the mounting frame 1 around the rotation connecting shaft 11. By rotating the working unit support frame 2 in the vertical direction, the rotation shaft as the first rotation center portion 30 of the rotation frame 3 and the rotation shaft as the second rotation center portion 50 of the rotation rod 5 can be easily performed. Can be adjusted vertically.

  The position of the ridge forming work part 4 is changed in a state where the rotation axes of the rotation frame 3 and the rotation rod 5 are substantially vertical. For example, when the position of the heel forming work unit 4 is to be changed from the forward work position shown in FIG. 3 to the reverse work position shown in FIG. 4, the lock pin 71 is lowered by operating the operation handle 74, The engagement with the engagement hole 700 of the fixing plate 70 of the fixing means 7 is released.

  As a result, the rotating frame 3 can be rotated approximately 180 degrees in the horizontal direction. This rotation is performed manually by the operator, and is rotated according to the rotation trajectory of the rotation rod 5 around the second rotation center 50 of the rotation rod 5. As the outer frame 31 of the rotating frame 3 automatically slides and moves toward the inner frame 32 according to the rotation, the length of the rotating frame 3 is automatically shortened. The position where the length of the rotating frame 3 becomes the shortest is when the ridge forming work section 4 is in a position on the rear side of the tractor. The position on the rear side of the tractor by the ridge forming work unit 4 is also a non-working position that is located during movement or the like.

When the position of the eaves forming work section 4 starts to move further from the rear side of the tractor to the backward movement position shown in FIG. 4, the outer frame 31 of the rotating frame 3 slides away from the inner frame 32 according to the rotation. Because of the movement, the length of the rotating frame 3 is automatically increased.
After the hook forming work unit 4 stops at the reverse working position, the operation handle 74 is operated in the reverse direction, the link lot 72 is rotated via the wire cable 73, the lock pin 71 is raised, and the engagement hole 700 is moved. Engage. Thereby, the rotating frame 3 is fixed.

  If the rotation rod 5 is a turnbuckle, its length can be changed and fixed, and the position from the tractor at the time of the work of the hook forming work part 4 can be adjusted by offset. Further, for example, when the length of the rotating rod 5 is made shorter, the turning track of the hook forming work unit 4 becomes a track closer to the tractor side. Therefore, when the heel forming work portion 4 is set to a non-working position such as when moving, the heel forming work portion 4 is closer to the tractor, so that the balance during traveling is improved.

  As a wrinkle forming device, there is less burden on the operator's work, which is convenient and highly available.
