Next, when moving during non-working such as road running, for example, after moving the unworked portion of the old ridge A, the left side of the moving direction of the ridge coating machine main body 1 is moved. When the operation handle 19 of the hook 16 between the upper and lower fixed arms 13 is rotated in the direction away from the stopper 20, the hook 16 of the operation handle 19 opens around the mounting shaft 15 against the toggle spring 21. The rotation of the hook 16 causes the engagement recess 17 of the hook 16 to be disengaged from the fixing pin 108 fixed to the upper turning arm 100 of the turning frame 97, and the fixing of the fixing pin 108 is released.

Further, in a state in which the ridger body 1 is lifted by the three-point suspension mechanism of the tractor T and the rotary 55 and the ridger body 98 are separated from the ground, the ridger 98 is moved forward by the ridger body 1. When the rotating frame 97 is pushed toward the rear of the ridge coating machine main body 1 in the same manner as when moving toward the right or left side with respect to the direction, the upper rotating arm 100 and the lower The pivot arm 101 is pivoted toward the rear of the levee coating machine main body 1 about the vertical center axis 99 of the upper and lower sides of the case main body 23 of the transmission device 6.

Then, the fixing means 12 for the upper rotating arm 100
When the second fixing pin 133 comes into contact with one side of the fixing frame 8 of the ridge coating machine main body 1 and the turning of the turning frame 97 is temporarily stopped, the operation handle 131 of the fixing means 122 is turned. When operated, the rotating operation body 132 of the operation handle 131 is configured such that the inclined portion 129 of the cam surface 130 at the lower end surface slides along the inclined portion 126 of the cam surface 127 at the upper end portion of the fixed pipe 124 and the coil is rotated. It is moved upward while pulling up and down the movable rod 134 against the spring 135.

The horizontal portion 128 of the cam surface 130 of the rotary operation body 132 rides on the horizontal portion 125 of the cam surface 127 at the upper end of the fixed pipe 124, and the rotary operation body 13
Fixing pin at the lower end of the vertical moving
133 is raised into the guide hole 123 of the fixed pipe 124,
The fixing pin 133 comes off one side of the fixing frame 8 of the ridge coating machine main body 1.

Then, the rotating frame 97 is attached to the ridge coating machine main body 1.
When the upper pivot arm 100 of the pivot frame 97 is further slightly pushed toward the rear of the ridge coater main body 1, the upper pivot arm 100 of the pivot frame 97 is moved onto the fixing frame 8 of the ridge coating machine main body 1.
The rotation of the upper rotation arm 100 is stopped when the fixing pin 133 of the 122 is positioned on the engagement hole 7 of the fixing frame 8.

When the operation handle 131 of the fixing means 122 is turned, the turning operation body 13 of the operation handle 131 is turned.
In 2, the horizontal portion 128 of the cam surface 130 is disengaged from the horizontal portion 125 of the cam surface 127 at the upper end of the fixed pipe 124, and the rotating operation body 132 is pulled down by the return force of the coil spring 135.

Then, the inclined portion 129 of the cam surface 130 is engaged with the inclined portion 126 of the cam surface 127 of the fixed pipe 124, and the up-and-down moving rod 134 of the rotary operation body 132 returns the coil spring 135. Lowered by force,
The fixing pin 133 at the lower end of the
23, it is fitted into the engaging hole 7 of the fixed frame 8.

Therefore, the rotating frame 97 having the ridge body 98 is fixed to the fixed frame 8 of the ridge coating machine main body 1 in a state of extending rearward. In other words, the rotating frame 97 having the ridge coating body 98 is positioned at a substantially middle portion of the ridge coating machine main body 1 without being shifted to the right side or the left side with respect to the traveling direction of the ridge coating machine main body 1, and maintains the weight balance. In this state, it is fixed to the fixed frame 8 of the ridge coating machine main body 1.

[0132] Since the weight of the ridge coating machine main body 1 is maintained as a whole, it can be moved in a stable state without a risk of overturning during non-working such as running on a road.

The lifting operation of the fixing pin 133 of the fixing means 122 is not limited to the case where the fixing pin 133 is brought into contact with one side of the fixing frame 8 of the ridge coating machine main body 1 and then the lifting operation is performed. After the fixing of the fixing pin 108 of the moving arm 100 is released, the fixing pin 133 of the fixing means 122 is pulled up, and the fixing pin 133 is retracted into the guide hole 123 of the fixing pipe 124.
