Reference numeral 2 denotes a support frame, the base of which is pivotally supported by a rotating shaft 4 provided at a substantially central portion of the rear portion of the mounting frame 1, and the flange forming portion 3 is disposed at the other end via a pipe frame 22. It becomes. The pipe frame 22 is configured to be slidable on the outer periphery of the support frame 2. The ridge forming unit 3 includes a banking device having excavation claws 36, a ridge top surface earthing device, and a ridge forming device.

  Reference numeral 43 denotes a connecting rod, which spans between a first pin 41 positioned forward in the traveling direction from the rotating shaft on the mounting frame side, and a second pin 42 provided on the upper part of the pipe frame rod 22 on the flange forming portion side. It is a thing. In this embodiment, the connecting rod 43 has a turnbuckle structure and has left and right screw shafts inserted into both ends of the central body frame. The left and right screw shaft ends are fixed to the first pin 41 and the second pin 42. The length of the connecting rod is expanded and contracted by rotating the central body.

  Reference numeral 52 denotes a double wide-angle joint. Power is conducted from the tractor PTO shaft to configure the relay transmission unit 5, and the rotational force is transmitted to the input transmission unit 54 of the rod forming unit 3. A boss shaft 23 is connected to the base portion of the support frame 2 in the vertical direction, is provided so as to be rotatable with respect to the rotating shaft 4, and has 24 fixing plates provided horizontally. Reference numeral 6 denotes an electric motor unit which gives a control instruction for releasing the lock pins 62 to the fixing plate 24 via the link rod 61. Reference numeral 65 denotes an electric motor, which moves the link rod 61 up and down by rotating a rotation gear 66 via a drive pinion.

  FIG. 2 shows a planar state in which the heel forming portion 3 of FIG. 1 is set at the forward work position and is turned 180 degrees around the rotation shaft 4 to be in the reverse work position. A transmission unit 5 is provided below the central portion of the mounting frame 1, and the transmission unit 5 is provided with an input shaft 51 input from a tractor, and connects the front end of the double wide-angle joint 52 to the rear end. The other end of the double wide-angle joint 52 is connected to the transmission shaft 53 of the input transmission case 54, and the mounting angle with respect to the input shaft 51 and the bending angle with respect to the input transmission shaft 53 are substantially symmetrical. Accordingly, the transmission force of the double wide-angle joint 52 in the reverse operation in which the heel forming portion is turned 180 degrees with respect to the mounting frame 1 is constant without change.

  Reference numeral 2 denotes a support frame. A boss shaft 23 is provided at the front end, and the boss shaft 23 is supported so as to be pivotable about the rotation shaft 4. Reference numeral 22 denotes a pipe frame, which is slidably provided on the outer periphery of the support frame 2 described above.

The original gear 72 rotates the receiving gear 73 provided at the base of the support frame 2 in the F2 direction with the vertical axis 74 as a fulcrum. At this time, the support frame 2 is turned 180 degrees in the direction F3, and the hook forming portion is set to the position of the reverse operation in FIG. Conversely, when returning to the forward work position, the forward button of the control case 75 is pushed and the electric cylinder 7 is extended, and the reverse operation is set.

  In FIG. 5, the operation of releasing the fixation of the fixing means will be described. FIG. 5 shows a state in which the support frame 2 is fixed at a position during forward operation. That is, three engagement holes 63, 63 a, 63 b of the fixing plate 24 are provided, and the second engagement hole 63 a is moved from the position where the lock pin 62 is engaged, and the third engagement hole is moved. The position of the reverse work of 63b is sequentially released and inserted. The operation of the electric motor unit 6 will be described. When the electric motor 65 is turned on, the rotation gear 66 is rotated, the link rod 61 is pulled up, one bracket of the link rod 64 is pulled up, and the other bracket is lowered and locked. The pin 65 descends and is released from the engagement hole 63 of the fixing plate 24, and the travel hole engagement hole 63a and the reverse operation engagement hole 63 are selected and fixed by turning the support frame 2. is there.

  When the connecting rod 43 is looped over the first pin 41 positioned in front of the rotation shaft 4 on the mounting frame 1 side and the second pin 42 on the hook forming portion side and turned to the traveling position, the hook forming work portion rotates. The operation of moving closer to the shaft 4 side will be described.

  In FIG. 6, the distance between the first pin 41 and the rotating shaft 4 in the left or right working state is L1, and the distance between the rotating shaft 4 and the second pin 42 is L2. Assuming that the length of the connecting rod 43 spanning the first pin 41 and the second pin 42 is L, the hook forming portion having a length L smaller than the L1 + L2 is linear in the traveling direction where the support frame 2 is in the traveling position. In this case, the pipe frame 22 slides by the difference in length, and the center of gravity of the ridge forming work portion approaches the rotating shaft 4 side.
