Slide plates 202 are movably embedded in the two slide grooves 208, and further comprising: a U-shaped plate 203, which is fixedly installed at the bottom of the slide plate 202, and a rotating rod 205 is movably embedded at the center of the U-shaped plate 203, and a grinding tool 206 is fixedly installed at one end of the rotating rod 205, and a motor 204 is fixedly installed at the center of the bottom of the slide plate 202, and the output end of the motor 204 is fixedly installed on the rotating rod 20 5, an L-shaped block 4 is fixedly installed on the opposite side of the slide plate 202, a guide block 404 is fixedly installed on the bottom of the two L-shaped blocks 4, an annular block 401 is fixedly installed on the outer surface of the two guide blocks 404, an annular baffle 402 is fixedly installed on the top of the annular block 401, a rubber baffle 403 is fixedly installed on the bottom of the annular block 401, an annular groove 207 is provided on the outer surface of the grinding tool 206, one end of the two guide blocks 404 is movably embedded in the annular groove 207, the diameter of the top of the rubber baffle 403 is smaller than the diameter of the bottom, and the rubber baffle 403 is made of wear-resistant material.

[0026] In this embodiment, the vehicle body 1 is pushed to move the device, and the controller is used to start the motor 204, so that its output shaft drives the rotating rod 205 to rotate, and synchronously drives the grinding tool 206 to rotate, so as to cut and grind the concrete protrusion, and synchronously causes the guide block 404 to slide inside the annular groove 207. Under the action of the annular baffle 402, the splashing protrusion can be blocked, and under the action of the rubber baffle 403 having a certain elasticity, when the device moves and encounters a protrusion, the friction can be reduced, and the rubber baffle 403 can be in close contact with the ground, so that the debris is inside the rubber baffle 403. In this way, when the concrete protrusion is polished with a grinder, the protrusion can be prevented from splashing, thereby avoiding harm to nearby personnel.

[0027] Embodiment 2, as Figure 1-4As shown, a square plate 3 is fixedly installed on the other side of the skateboard 202, and an air suction pipe 302 is fixedly embedded on the top of the two square plates 3. An air hood 303 is fixedly installed on one end of the two air suction pipes 302. A dust suction device 301 is fixedly installed on the top of the two square plates 3. The air suction ends of the two dust suction devices 301 are respectively fixedly installed on the other ends of the two air suction pipes 302. A hydraulic telescopic rod 201 is fixedly installed at the center of the bottom of the vehicle body 1, and one end of the hydraulic telescopic rod 201 is fixedly installed at the center of the top of the skateboard 202. One ends of the two air suction pipes 302 are respectively connected with the interiors of the two air hoods 303. The two air hoods 303 are arranged in a trumpet shape. The width of the slide 208 is adapted to the width of the skateboard 202. A tool placement box 101 is fixedly installed on one end of the top of the vehicle body 1, and an item placement box 102 is fixedly installed on the other end of the top of the vehicle body 1.

[0028] In this embodiment, the dust suction device 301 is started by controlling the controller so that its suction end sucks air into the suction pipe 302, and with the cooperation of the hood 303, the debris generated by grinding the concrete can be sucked. Since the grinding tool 206 can generate an outward centrifugal force when it rotates, the debris can follow the rotation of the grinding tool 206 and move to the bottom of the hood 303. In this way, the debris generated by grinding the concrete protrusion can be quickly sucked, thereby avoiding the debris from remaining on the concrete road, thereby improving the aesthetics of the road. When this device is not needed, the hydraulic telescopic rod 201 can be started by controlling the controller to shrink, thereby driving the slide plate 202 to move upward along the inside of the slide groove 208, thereby allowing the grinding tool 206 and the rubber baffle 403 to be separated from the ground, making it convenient for this device to move.

[0029] Working principle: When in use, the vehicle body 1 is pushed to move the device, and the controller is used to control the motor 204 to start, so that its output shaft drives the rotating rod 205 to rotate, and the grinding tool 206 is driven to rotate synchronously to cut and grind the concrete protrusions, and the guide block 404 is synchronously made to slide inside the annular groove 207. The annular baffle 402 can block the splashing protrusions, and the rubber baffle 403 has a certain elasticity. When the device moves and encounters a protrusion, the friction can be reduced, and the rubber baffle 403 is in close contact with the ground, so that the debris is inside the rubber baffle 403. In this way, when the grinder is used to grind the concrete protrusion, the protrusion can be prevented from splashing, thereby avoiding harm to nearby personnel, and the controller is used to control the vacuuming synchronously. The device 301 is started, so that its suction end sucks air into the suction pipe 302, and with the cooperation of the hood 303, the debris generated by grinding the concrete can be sucked. Since the grinding tool 206 can generate an outward centrifugal force when rotating, the debris can follow the rotation of the grinding tool 206 and move to the bottom of the hood 303. In this way, the debris generated by grinding the concrete protrusion can be quickly sucked, thereby avoiding the debris from remaining on the concrete road, thereby improving the aesthetics of the road. When this device is not needed, the hydraulic telescopic rod 201 can be controlled by the controller to start and shrink, thereby driving the slide plate 202 to move upward along the inside of the slide groove 208, thereby allowing the grinding tool 206 and the rubber baffle 403 to be separated from the ground, making it easier for the device to move.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
