Technical Field

[0001] The present application relates to the technical field of rammers, and in particular to a hydraulic rammer. Background Art

[0002] The tamping machine is a compacting machine that compacts backfill soil in layers by using impact and impact vibration. It can also use impact and impact vibration to break up the road surface in layers, which is used for trenching and repairing old roads. As a type of tamping machine, hydraulic tamping machines are also widely used.

[0003] The Chinese patent with the announcement number CN218244290U discloses a tamping machine for garden maintenance, including a machine body, a tamping plate installed at the bottom end of the machine body, a convex block fixedly connected to the front end of the tamping plate, a fixed shaft fixedly connected to the rear side of the tamping plate, a moving mechanism installed on one side of the fixed shaft, a handrail installed on one side of the upper end of the machine body, a mounting groove is provided in the middle of the rear end of the handrail, a holding mechanism is installed on one side of the mounting groove, the moving mechanism includes a bracket, universal wheels are installed on both sides of the surface of the side away from the tamping plate, the holding mechanism includes a sleeve, a connecting block is fixedly connected to one side of the outer wall of the sleeve, and a handle is fixedly connected to one end of the connecting block. In the utility model, a convenient mobile tamping machine is realized, which reduces the labor intensity of workers and reduces some vibrations caused to workers when the tamping machine is in operation.
