[0023] The working principle of the hydraulically driven rammer is to drive the piston to perform high-speed reciprocating motion through the high-pressure liquid generated by the hydraulic system, exerting impact force on the fill to achieve a compaction effect.

[0024] The rolling mechanism is arranged on the outer side of the bottom end of the carriage body 11, and the rolling mechanism includes a sliding limit rod 3, the top end of the sliding limit rod 3 is fixedly connected to a mounting rod 31, and the mounting rod 31 passes through the inner side wall of the carriage body 11, and the outer side wall of the mounting rod 31 is threadedly connected to a connecting screw sleeve 32, and an upper baffle 36 is arranged in the middle of the connecting screw sleeve 32, and the connecting screw sleeve 32 is rotatably connected to a rotating baffle 33 near the bottom, and the upper baffle 36 is arranged on the top of the rotating baffle 33 for limiting the rotating baffle 33, and the mounting rod 31 is threadedly connected to the inner side wall of the carriage body 11. Threaded grooves are provided on the outer side and the inner side of the connecting screw sleeve 32 for threaded connection with the mounting rod 31. After the rotating baffle plate 33 is unfolded, it is connected to the carriage body 11 for limiting. The bottom of the sliding limiting rod 3 is fixedly connected with an arc-shaped baffle plate 34. The inner side wall of the arc-shaped baffle plate 34 is rotatably connected with a roller 35.

[0025] Working principle: When the device is needed, firstly, the mounting rod 31 is passed through the carriage body 11, and then comes out from the top of the carriage body 11, then the rotating baffle 33 on the outside of the mounting rod 31 is rotated out, so that the rotating baffle 33 is connected with the top of the carriage body 11, and then the connecting nut 32 is rotated to make the connecting nut 32 descend through the thread of the mounting rod 31, and the arc baffle 34 and the roller 35 are limited to the bottom of the carriage body 11, and then the flange 1 22 and the flange 2 24 are spliced ​​together, and then the bolt hole 1 23 and the bolt hole 25 are set. The bolts 26 are installed on the inside to fix the output head 21 and the rammer body 2 together, so that the hydraulic driving machine 13 can carry the rammer body 2 to compact the soil. When in use, the rammer can be compacted by walking inverted. First, the ground is rolled with the roller 35, and then the rammer body 2 is used to compact the ground to improve work efficiency. The hydraulically driven rammer uses the hydraulic oil inlet kinetic energy + the upper accumulator kinetic energy to push the cylinder rod upward to compress the nitrogen chamber. After pushing to the highest point, the reversing valve switches direction. The hydraulic oil inlet kinetic energy + the nitrogen compression kinetic energy pushes the cylinder rod to quickly downward to knock to complete the tamping work.
