A vibration motor 9 is fixedly mounted on the upper surface of the mounting frame 8 by means of bolts.

[0024] When the roller 5 contacts the ground and rotates with the pin as the center, the sphere 66 will be driven to rotate in the slide bar 61. At the same time, the slide bar 61 is pulled or pushed to make the spring 63 generate a force, so that the roller 5 can be in close contact with the ground; the lower end of the slide bar 61 passes through the push block 7, and a ball groove 65 is provided in the lower end of the slide bar 61, and a sphere 66 is rotatably arranged in the ball groove 65.

Starting the electric telescopic rod 4 can push the roller 5 to move down and contact the ground. When the vibration motor 9 is started, the roller 5 vibrates to compact the ground. The roller 5 is connected to the ground in a rolling manner, and can better contact the ground. In addition, the mounting frame 8 on the outer periphery of the roller 5 is connected to the push block 7 in a rotational manner through a pin rod, and the roller 5 will rotate clockwise or counterclockwise at a small amplitude at the lower end of the push block 7 with the pin rod as the center of the circle; the roller 5 can be a solid metal or hollow design;
