During the rotation of the first spline sleeve 11, the cutting blade 2 can be driven to rotate through the first spline shaft 12, and the two sliding blocks 5 can be driven to move relative to each other by rotating the bidirectional screw 6, and the first spline shaft 12 is driven to slide in the first spline sleeve 11 while moving, thereby driving the two cutting blades 2 to move relative to each other, making it easy to adjust.

[0032] In the utility model, a rotating plate 7 is rotatably provided on one side of the cutting disc 2, and the cutting disc 2 is rotatably provided on the outer side of the rotating plate 7. One end of the first spline shaft 12 passes through the rotating plate 7, so that the rotating point of the rotating plate 7 is coaxial with the first spline shaft 12.

[0034] In the utility model, the knocking mechanism includes a sliding plate 19 that slides through the top of the cart 1, and a counterweight block 21 for knocking on the ground is detachably provided at the bottom of the sliding plate 19. One side of the sliding plate 19 is transmission-connected to the first spline sleeve 11. By starting the motor 10, the first spline sleeve 11 can be driven to rotate.

[0038] Working principle: When in use, move the device to the road surface to be cut, connect the power supply to the device, start the motor 10, the motor 10 can drive the first spline sleeve 11 to rotate, the rotation of the first spline sleeve 11 can drive the first spline shaft 12 to rotate, and the first spline shaft 12 can drive the cutting blade 2 to rotate through the synchronous wheel 8 and the synchronous belt 9 during the rotation of the first spline shaft 12 to cut the road surface, and open the valve on the water pipe 3. At this time, the water in the water tank 4 will flow into the water pipe 3 and spray onto the cutting blade 2 to remove dust. At the same time, the device is pushed and driven to move during the cutting process, so that it moves while cutting;

[0039] The first spline sleeve 11 rotates and drives the cam 18 to rotate. When the cam 18 contacts the limit block 20, the sliding plate 19 is driven to move upward, which drives the counterweight 21 to move upward. When the cam 18 is separated from the limit block 20, the counterweight 21 can move downward under its own gravity to knock the cut road surface and break it.

[0040] When the cutting depth needs to be adjusted, the electric push rod 16 is started, and the electric push rod 16 can drive the rotating plate 7 to rotate on the first spline shaft 12 through the second spline sleeve 14 and the second spline shaft 15, so as to adjust the height of the cutting blade 2 from the ground;

[0041] When the cutting width needs to be adjusted, the bidirectional screw 6 is rotated. The bidirectional screw 6 can drive the two sliding blocks 5 to move relative to each other. The movement of the sliding blocks 5 can drive the first spline shaft 12 to slide in the first spline sleeve 11, and at the same time drive the second spline shaft 15 to slide in the second spline sleeve 14, so that the distance between the two cutting blades 2 can be adjusted.
