[0037] Further, the worker only needs to turn over the rocker arm 1101 to be flat downward and then start the driving motor 2201 to complete the cleaning work of the impurities in front of the road surface during the driving process of the carrier vehicle body 3, the cleaning brush 2403 rotates to stir the impurities located on the right side of the arc-shaped baffle 2104, so that the impurities are far away from the central axis during the driving process of the carrier vehicle body 3, the arc-shaped baffle 2104 can push the impurities outward during the moving process to complete the cleaning of the impurities, so that the device can ensure that there is no impurity residue after cleaning the impurities on the road surface, and the worker can not have data error due to the interference of impurities when measuring the asphalt pavement, and the operation is simple and convenient for the worker to use.

[0038] In actual operation, when the device is in use, the workers first pull the two pull rods 1302 on the front and back sides of the upper part inward synchronously. The inward movement of the pull rods 1302 drives the positioning clamping plates 1203 to move inward through the movement of the sliding rods 1301 and the sliding cylinders 1201, and the inward movement of the positioning clamping plates 1203 retracts them into the carrier body 3 to release the positioning of the rocker arm 1101. Then the workers can turn the rocker arm 1101 to the right to a position below the upper positioning clamping plate 1203, and then release the pulling of the upper pull rod 1302 and pull the lower pull rod 1302 inward. At this time, the lower positioning clamping plates 1203 retract into the carrier body 3, and then continue to turn the rocker arm 1101 downward until the bottom of the rocker arm 1101 is in close contact with the top of the cushion block two 1106. At this time, the lower pull rod 1302 is released, and the lower sliding cylinder 1201 drives the positioning clamping plate 1203 to move outward under the action of the compression spring 1202 and is clamped in the carrier body 3. At this time, the bottom of the lower positioning clamping plate 1203 is in contact with the top of the rocker arm 1101, and the flat state positioning of the rocker arm 1101 is completed through cooperation with the cushion block two 1106.

[0039] Then the workers start the drive motor 2201, which drives the worm one 2203 to rotate through the drive shaft 2202. The rotation of the worm one 2203 drives the worm two 2303 to rotate through the worm gear one 2301 and the rotating shaft 2302. The rotation of the worm two 2303 drives the cleaning brush 2403 to rotate through the worm gear two 2401 and the rotating shaft 2402.

[0040] Then the workers can start the carrier body 3 to drive it to the right. During the movement of the carrier body 3, the plurality of cleaning brushes 2403 rotate to push the impurities located at the right side of the arc-shaped baffle 2104 to the front and back sides. Then the arc-shaped baffle 2104 pushes the impurities to the right, and they gradually deviate to the front and back sides along the arc surface of the right side of the arc-shaped baffle 2104. At this time, the cleaning of the impurities on the road surface is completed, which facilitates the subsequent use of laser to measure the flatness of the asphalt pavement.
