[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] like Figure 1 As shown, the earthwork backfilling and compaction device provided by this utility model includes a compaction top plate 1, an installation plate 2, and an adjustment frame 3. A vibration mechanism 4 is installed on the compaction top plate 1. The compaction top plate 1 is in contact with the earthwork, and the vibration mechanism 4 causes the compaction top plate 1 to vibrate and compact the earthwork. The installation plate 2 is an installation structure. The compaction top plate 1 is installed on the support of the trolley through the installation plate 2. The compaction top plate 1 is installed below the installation plate 2 through the telescopic and resettable adjustment frame 3. The height of the compaction top plate 1 can be adjusted and adapted by the telescopic movement of the adjustment frame 3.

[0015] In this utility model, the adjusting frame 3 includes two sets of scissor supports 3-1. The upper and lower ends of one side of the two sets of scissor supports 3-1 are respectively hinged to the compacted top plate 1 and the mounting plate 2 through hinge seats 3-2. The upper and lower ends of the other side of the two sets of scissor supports 3-1 are respectively slidably engaged with the compacted top plate 1 and the mounting plate 2. The distance between the compacted top plate 1 and the mounting plate 2 is changed by the angle change between the two cross rods of the scissor supports 3-1. A connecting shaft 5 is provided between the two sets of scissor supports 3-1. The two ends of the connecting shaft 5 are respectively rotatably installed in the middle of the scissor supports 3-1. A return spring tube 6 is connected between the connecting shaft 5 and the mounting plate 2.
