- the rotating body 64 is rotatably supported on the outer peripheral surface of the housing 51a of the motor case 51, and a deceleration mechanism 66 is provided inside the rotating body 64.
- the upper part of the cylindrical body 93 is mounted on the mounting flange 65 provided at the axially intermediate portion on the outer peripheral surface of the rotary body 64, and the rotary body 64 projects into the cylindrical body 93. Therefore, the distance between the hydraulic motor 50 and the cutting blade mounting body 99 of the road surface cutting device A is shortened, and the cutting blade mounting body 99 is connected to the hydraulic motor 50 via the rotating body 64.
- the housing 51 of the case 51 is firmly supported by the housing 51a, so that the cutting blade mounting body 99 does not fluctuate due to the cutting resistance during road surface cutting, and the output torque of the hydraulic motor 50 is applied to the cutting blade mounting body 99. It can be communicated reliably.
- the road surface cutting device A is set to a substantially horizontal posture or a diagonally upward posture by swinging the boom 4 and the arm 6 upward, the side wall of the tunnel, etc. Can be cut.
- the deformation of the cushioning member 32 in the rotation direction during heavy cutting of the road surface by the cutting blade is restricted, and the first and second side surface cutting blades 106, Buffer material for heavy cutting of vertical surface with 107
- a torsion device 120 is mounted to restrict vertical deformation of the towel.
- the spring device 120 includes a first member 122 attached to the horizontal plate 21 at intervals of approximately 90 degrees and a motor mounting member. It is formed by a prism-shaped second member 122 attached to the lower surface of 3 at an interval of about 90 degrees. The lower end 12a of the first member 1221 is bent in a hook shape and faces the lower surface of the motor mounting member 30 and the second member 122.
- the lower end 1 2 1a of the first member 1 2 1 prevents the shock absorbing member 32 from being deformed in the rotation direction by contacting the second member 1 2 2, and the lower end 1 1 of the first member 1 2 1 21 a contacts the lower surface of the motor mounting member 30 to prevent the shock absorbing member 32 from being deformed in the vertical direction.
- a trench excavator called a backhoe mounted on the rear part of a vehicle body such as a bulldozer, a dozer shovel, a wheel loader, or an on-load truck.
- a road surface cutting device may be attached to the arm of a groove excavator in which the machine body is pivotably mounted on the body of the vehicle.
