[0104] The lifting lug 409 at the top of the compacting vibrator 403 is suspended on the hanger 307 at the top of the compacting assembly bracket 303 at the rear side of the bracket assembly 3 through a sling.

[0105] There are at least two rectangular steel plates 406 and at least two steel barrels 407. The outer wall of the steel barrel 407 is an inwardly concave arc. The arc structure enables the steel barrel 407 to have a deformation function. When the compacting vibrator 403 drives the second tamping plate 405 and the first tamping plate 402 to move up and down, the rectangular steel plate 406 located on the outside moves up and down. At this time, because the steel barrel 407 has a deformation function, when the rectangular steel plate 406 moves up and down, the connecting steel plate 408 does not move.

[0106] When the compacting vibrator 403 is working, the hydraulic oil is sent into the hydraulic cylinder through the compacting component hydraulic oil pipe 401, so that the compacting vibrator 403 on the second compacting plate 405 and the first compacting plate 402 vibrates through the eccentric shaft, and the flow direction and pressure of the hydraulic oil are adjusted by controlling the hydraulic valve to achieve the lifting and lowering and vibration frequency adjustment of the second compacting plate 405 and the first compacting plate 402.

[0107] The lifting assembly 5 is used to adjust the thickness after paving. The vertical hydraulic telescope 501 provides power to drive the lifting assembly top plate 502, the lifting assembly connecting bracket 503, and the lifting assembly support column 504 to move up and down, thereby making the bracket assembly 3, the compacting assembly 4, and the horizontal telescopic assembly 6 move up and down synchronously to achieve the adjustment of the paving thickness.

[0108] The horizontal telescopic component 6 realizes paving of different widths. Specifically, the horizontal hydraulic telescopic device 601 provides power to drive the horizontal telescopic component sliding frame 604 and its connected horizontal hydraulic telescopic device connecting steel plate 605 and the front row compaction component 4 to move synchronously. The rear row compaction component 4 is mainly responsible for compacting the inner mixture and moves asynchronously. At the same time, the horizontal telescopic component limiter 601 makes the telescopic operation track within the fixed slideway, so as to realize the compaction of paving mixtures of different widths.

[0109] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
