In the construction process of some small roads By compacting the road surface, the soil base can obtain a certain density, improve strength and stability, reduce the probability of deformation of the roadbed under driving or natural factors, and increase the service life of the road surface. Therefore, a compaction device is needed. When the No. 1 motor 20 drives the driving wheel 21 to rotate, the belt 25 drives the driven wheel 24 and the rotating shaft 23 to rotate together. When the rotating shaft 23 rotates, the eccentric wheel 27 rotates accordingly and contacts the pressure plate 19, generating up and down pressure fluctuations, so that the pressure plate 19 vibrates up and down under the cooperation of the compression spring 18 and the damper, thereby compacting the road, so that the pressure plate 19 can vibrate up and down under the action of the eccentric wheel 27, thereby realizing automatic compaction of the road.

At the same time, the scraper 31 cleans the adhesion on the surface of the compaction roller 29 to ensure the compaction effect.

[0030] Working principle: the operator pushes the device through the push handle 32 to perform compaction operation. By starting the pump 15, the water in the water tank 14 is transported to the nozzle 13 through the delivery pipe 12. The nozzle 13 then sprays water onto the road to be compacted. At the same time, the drive motor 4 is started. The drive motor 4 drives the cam 5 to rotate, so that the sliding sleeve 6 slides up and down with the cooperation of the connecting rod 9. The sliding sleeve 6 drives the connecting plate 8 to swing left and right when it moves, so that the fixed plate 10 and the nozzle 13 can swing left and right, so that the nozzle 13 can swing within a certain range, increase the compaction area of ​​the spraying, so that the spraying is more uniform, and the dust treatment effect is improved. The nozzle 13 is at the front end of the device.

[0031] When the No. 1 motor 20 drives the driving wheel 21 to rotate, the belt 25 drives the driven wheel 24 and the rotating shaft 23 to rotate together.
