Through the air suction function of the air pump 801 combined with the cleaning pipe 803, debris on the road surface can be effectively sucked and collected.

[0034] Working principle: When road repair is required, the mixing box 4 is opened, the material to be repaired is placed in the mixing box 4, and the box cover 401 is closed. The motor 5 is started, the mixing unit starts to work, and the connecting block 503 is driven to rotate through the connecting rod 1 502. Since the large gear 501 is meshed with the small gear 504, the two mixing shafts 505 rotate synchronously. The mixing bar 506 and the mixing blade 507 on the mixing shaft 505 rotate accordingly to evenly mix the repair material in the mixing box 4. After the mixing is completed, the mixed material is transported to the road surface position to be repaired through the perfusion pipe 9.

[0035] The cylinder 7 is controlled to lower the roller 703 to a suitable position. The operator pushes the push rod 3 to move the maintenance structure along the road surface, and the roller 703 rolls on the material to achieve smooth paving of the material.

[0036] After the repair is completed, the mixing unit and the flattening unit are turned off, and the mixing box 4 is cleaned. First, the connecting strip 403 is taken out from the connecting ring 402. Since the box pieces of the mixing box 4 are movably connected by hinges 404, the box pieces can be easily opened or closed. Then a high-pressure water gun is used to rinse the inside of the mixing box 4.

[0037] When the road surface needs to be cleaned, the suction pump 801 is started, and the operator pushes the maintenance structure to align the cleaning pipe 803 with the part of the road surface that needs to be cleaned. The suction pump 801 generates suction inside the cleaning box, and absorbs debris on the road surface through the cleaning pipe 803, thereby achieving rapid cleaning of the road surface.
