The rotating shaft 32 is rotatably mounted on the supporting member 2, and the output end of the driving motor 31 is connected to the rotating shaft 32 to rotate the rotating shaft 32.
The first vibratory wheel 33 is provided with a first eccentric hole 332, and the center of the first eccentric hole 332 is offset from the center of the first vibratory wheel 33. The second vibratory wheel 34 is provided with a second eccentric hole 342, and the center of the second eccentric hole 342 is offset from the center of the second vibratory wheel 34. The first vibration wheel 33 is sleeved on the rotation shaft 32 through the first eccentric hole 332, and is fixedly connected with the rotation shaft 32. Optionally, the rotating shaft 32 is interference fit with the first eccentric hole 332 to achieve a fixed connection. The second vibration wheel 34 is fitted over the rotation shaft 32 through the second eccentric hole 342, and is rotatably coupled to the rotation shaft 32. Optionally, the rotating shaft 32 is in rotational communication with the second eccentric aperture 342.
Alternatively, a positioning hole is formed in the rotating shaft 32, a fitting hole is formed in the first vibration wheel 33, and the first vibration wheel 33 is fixedly connected to the rotating shaft 32 by a bolt, which passes through the fitting hole and is connected to the positioning hole.

The first eccentric part 331 or the second eccentric part 341 is provided with a linkage rod 35. The rotation shaft 32 rotates to rotate the first vibratory wheel 33. When the first vibratory wheel 33 rotates, the first eccentric portion 331 touches the linkage rod 35 or the second eccentric portion 341 is touched by the linkage rod 35, and then the first vibratory wheel 33 and the second vibratory wheel 34 rotate simultaneously. Thus, the amplitude and the strength of vibration are improved.
In this embodiment, the first eccentric portion 331 and the second eccentric portion 341 have the same shape, and the linkage rod 35 is connected to the first eccentric portion 331.
The first vibration wheel 33 and the second vibration wheel 34 rotate to generate vibration, the generated acting force is transmitted to the shell barrel 1 through the supporting piece 2, and then the flat part 4 is driven to vibrate, so that the flat part 4 levels rock soil. According to the arrangement, the original manual tamping rock soil is changed, the working efficiency is improved, and the manpower is reduced.
In one embodiment, as shown in fig. 1-6, the driving motor 31 can drive the rotating shaft 32 to rotate in a first direction and a second direction opposite to the first direction. When the rotating shaft 32 rotates in the first direction, the first eccentric portion 331 and the second eccentric portion 341 are displaced in the axial direction of the rotating shaft 32. When the rotating shaft 32 rotates in the second direction, the first eccentric portion 331 and the second eccentric portion 341 at least partially overlap in the axial direction of the rotating shaft 32.
Specifically, the linkage rod 35 is connected to the first eccentric portion 331, and when the rotation shaft 32 drives the first vibration wheel 33 to rotate toward the first direction, the linkage rod 35 contacts with one end of the second eccentric portion 341 to drive the second vibration wheel 34 to rotate toward the first direction. At this time, the first eccentric portion 331 is opposite to the second eccentric portion, i.e., is located at both sides of the rotating shaft 32, and there is no overlapping portion of the first eccentric portion 331 and the second eccentric portion 341 in the axial direction of the rotating shaft 32. At this time, the direction of the movement tendency of the center of gravity of the first eccentric portion 331 is opposite to the direction of the movement tendency of the center of gravity of the second eccentric portion 341. For example, the center of gravity of the first eccentric portion 331 moves downward, and the center of gravity of the second eccentric portion 341 moves upward. The vibration of the second eccentric portion 341 partially cancels the vibration of the first eccentric portion 331, thereby reducing the amplitude and vibration strength of the two portions as a whole.

When the rotating shaft 32 drives the second vibrating wheel 34 to rotate in the second direction, the linkage rod 35 contacts with the other end of the second eccentric portion 341 to drive the second eccentric wheel to rotate in the second direction. The first eccentric portion 331 and the second eccentric portion 341 partially overlap on the axis of the rotating shaft 32, and are located on the same side of the rotating shaft 32. At this time, the center of gravity of the first eccentric portion 331 moves in the same direction as the center of gravity of the second eccentric portion 341. For example, the center of gravity of the first eccentric portion 331 moves downward, the center of gravity of the second eccentric portion 341 moves downward. Thus, the vibration of the second eccentric portion 341 reinforces the vibration of the first eccentric portion 331, thereby improving the overall amplitude and vibration strength. By the arrangement, the amplitude intensity of the tamping device 10 can be controlled and adjusted, and workers can conveniently select the amplitude intensity according to actual needs.

When the vibration mechanism 3 drives the support plate 21 to move upward, the support plate 21 drives the buffer block 52 to move upward. When the buffer block 52 moves upward to the limit position, the buffer block 52 drives the connecting rod 51 to move upward. When the vibration mechanism 3 drives the support plate 21 to move downward, the support plate 21 drives the buffer block 52 to move downward. When the buffer block 52 moves downwards to the limit position, the buffer block 52 drives the connecting rod 51 to move downwards. So set up for remove asynchronous between backup pad 21 and the connecting rod 51, have certain delay nature, delayed the transmission of power between the two.
