[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1

[0027] See also Figures 1-6 A compacting and leveling device for earthwork engineering includes a compacting and leveling device body 100, a rotating shaft 200 is installed inside the compacting and leveling device body 100, and a rolling wheel 300 is installed on the side of the rotating shaft 200;

[0028] A shock-absorbing assembly 400 is provided inside the compaction and leveling device body 100. The shock-absorbing assembly 400 includes a fixed plate 401. The bottom of the fixed plate 401 is connected to a shock-absorbing rod 403 via a spring 402. A shock-absorbing groove 404 is provided inside the compaction and leveling device body 100. An elastic rubber block 405 is fixedly connected to the inner wall of the shock-absorbing groove 404. The bottom of the shock-absorbing rod 403 is fixedly connected to an arc-shaped force-bearing plate 406. The arc-shaped force-bearing plate 406 is located at the top of the rotating shaft 200 and contacts the rotating shaft 200. When the compaction and leveling device body 100 is in use and the rolling wheel 300 vibrates, the rotating shaft 200 can squeeze the arc-shaped force-bearing plate 406 and cause it to move. The arc-shaped force-bearing plate 406 drives the shock-absorbing rod 403 fixedly connected thereto to move in the shock-absorbing groove 404. The shock-absorbing rod 403 is subjected to friction from the elastic rubber block 405, thereby decelerating. The outer side of the arc-shaped force-bearing plate 406 is rotatably connected to a torsion spring rod 407, and the outer side of the torsion spring rod 407 is fixedly connected to a transmission rod 408. The transmission rod 408 is rotatably connected to a rubber wheel 409. The rubber wheel 409 is located at the bottom of the compaction and leveling device body 100 and is in contact with the compaction and leveling device body 100. When decelerating, the arc-shaped force-bearing plate 406 drives the torsion spring rod 407 rotatably connected thereto to move, causing the torsion spring rod 407 to drive the transmission rod 408 fixedly connected thereto to move, causing the transmission rod 408 to drive the rubber wheel 409 rotatably connected thereto to roll at the bottom of the compaction and leveling device body 100, thereby further damping the shock-absorbing rod 403 and the arc-shaped force-bearing plate 406, thereby further performing double damping on the shock-absorbing rod 403 and the arc-shaped force-bearing plate 406, thereby improving the rolling effect of the device.

[0029] During use, when the compaction and leveling device body 100 is in use and the rolling wheel 300 vibrates, the rotating shaft 200 can squeeze the arc-shaped force-bearing plate 406 and move it, and the arc-shaped force-bearing plate 406 drives the shock-absorbing rod 403 fixedly connected to it to move in the shock-absorbing groove 404, and the shock-absorbing rod 403 is subjected to the friction of the elastic rubber block 405 to slow down; at the same time, the arc-shaped force-bearing plate 406 drives the torsion spring rod 407 rotatably connected to it to move, so that the torsion spring rod 407 drives the transmission rod 408 fixedly connected to it to move, so that the transmission rod 408 drives the rubber wheel 409 rotatably connected to it to roll at the bottom of the compaction and leveling device body 100, thereby further reducing the shock of the shock-absorbing rod 403 and the arc-shaped force-bearing plate 406.

[0030] Example 2

[0031] See also Figures 1-6Based on the first embodiment, an alarm assembly 500 is installed on the side of the compaction and leveling device body 100. The alarm assembly 500 includes a hydraulic chamber 501. One end of the hydraulic chamber 501 is slidably connected to a force-bearing rod 502. The force-bearing rod 502 is located at the top of the shock-absorbing groove 404 and inside the spring 1 402. When the vibration amplitude is too large, the shock-absorbing rod 403 moves a long distance, thereby squeezing the force-bearing rod 502 and causing it to move. In conjunction with the hydraulic chamber 501 slidably connected to the force-bearing rod 502, the pressure within the hydraulic chamber 501 increases. The other end of the hydraulic chamber 501 is slidably connected to a pressure rod 503. An alarm body 504 is installed on the side of the compaction and leveling device body 100. An alarm switch 505 is installed on the side of the alarm body 504 and is located on the side of the pressure rod 503. When the pressure in the hydraulic chamber 501 increases, the pressure rod 503 slidably connected to the hydraulic chamber 501 moves, causing the pressure rod 503 to squeeze the alarm switch 505, thereby activating the alarm body 504 and sounding an alarm to remind the user that the vibration amplitude is too large.

[0032] During use, based on Example 1, when the vibration amplitude is too large, the shock-absorbing rod 403 moves a longer distance, thereby squeezing the force-bearing rod 502 and causing it to move, and cooperating with the hydraulic compartment 501 that is slidingly connected to the force-bearing rod 502, the pressure in the hydraulic compartment 501 increases, driving the pressure rod 503 that is slidingly connected to the hydraulic compartment 501 to move, causing the pressure rod 503 to squeeze the alarm switch 505, thereby activating the alarm body 504 and sounding the alarm.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
