[0027] Scraping strip 7 has elasticity, and is in extrusion contact with the top of corresponding compaction block 4.

[0028] The fixed block 6 has multiple sliding grooves 8, and multiple actuating components correspond one-to-one with the multiple sliding grooves 8. The actuating components include two sliding blocks 9, both of which are slidably connected in the sliding grooves 8. The same compression spring 11 is fixedly connected to one adjacent end of the two sliding blocks 9. The sliding block 9 is rotatably connected to the end near the gravity wheel 3. A roller brush 13 is coaxially fixedly connected to the outer periphery of the roller brush 12. The bottom of the roller brush 13 is in compression sliding contact with the outer periphery of the gravity wheel 3. The sum of the diameters of the two roller brushes 13 is less than the gap width between two adjacent compaction blocks 4. The two roller brushes 13 are initially located between the axes of two adjacent compaction blocks 4.

[0029] In the initial state, part of the roller brush 13 overlaps with the compaction block 4 around the gravity wheel 3.

[0030] A partition plate 10 is fixedly connected to the middle of the sliding groove 8, and a compression spring 11 is fixedly connected to the partition plate 10 in the middle.

[0031] A lever is fixedly connected to the separator 10. The lever is elastic and extends into the middle of the gap between two adjacent compaction blocks 4.

[0032] The cleaning mechanism includes a water tank 14, a water pump 15 installed inside the water tank 14, the input end of the water pump 15 is connected to the inside of the water tank 14, the output end of the water pump 15 is connected to a water outlet pipe 16, a water cavity 17 is opened in the fixing block 6, the end of the water outlet pipe 16 away from the water pump 15 is sealed and passes through the water tank 14, and is connected to the top of the water cavity 17, and multiple nozzles 18 are connected to the bottom of the water cavity 17, and the output ends of the multiple nozzles 18 are one-to-one pointing to multiple compaction blocks 4 in the same axis.

[0034] During operation, the vehicle body 1 moves, and the gravity wheel 3 rolls on the road surface through the mounting frame 2. The road surface is compacted by the compaction block 4 on the gravity wheel 3.

[0035] During the operation of the compacted block 4, materials are easily stuck to the compacted block 4.
