Then the limiting block moves away from the surface of the abutment block, and the abutment block is unrestrained. Pulling the noise reduction cover, the noise reduction cover moves and abuts the limiting ball. When the limiting ball moves, it causes the first spring to displace and deform, generating elastic force.

[0015] 2. In this utility model, by setting up a spraying device, when the equipment is in use, the user starts the pump, and then the control board controls the water flow into the pipes and connecting pipes. The water then sprays water onto the compaction head and the ground through the nozzles. By setting up the spraying device, dust splashed up by the equipment is effectively reduced, which plays a role in reducing dust in the working environment of the equipment. This reduces the possibility of dust being easily stirred up when the compaction head is compacting the ground, thus polluting the construction environment for the workers and improving the practicality of the equipment.
