[0002] During the road construction process, in order to ensure the stability of the foundation on both sides of the road, a vibratory rammer will be needed to compact the soil on both sides of the completed road. At the same time, in order to ensure that rainwater can be drained smoothly during the rainy season, the soil on both sides of the road will be compacted into a slope. The sloped soil includes a horizontal transition surface connected to the two sides of the completed road, and a slope surface connected to the outside of the horizontal transition surface. During the actual operation, the worker connects the upper end of the vibratory rammer to the mechanical arm of the excavator to start the compaction operation. During the compaction operation, the worker who needs to operate the excavator must constantly control the mechanical arm to adjust the angle between the working surface of the vibratory rammer and the horizontal ground, so as to realize the compaction of the soil on the horizontal transition surface and the slope surface. The operation is cumbersome and the compaction efficiency is low, so the traditional vibratory rammer still has certain limitations.

[0003] Therefore, a highway roadbed tamping and compacting device is needed to solve the above problems. Utility Model Content

In the utility model, the angle adjustment of the first vibration tamping device is realized by the first driving component, and the angle adjustment of the second vibration tamping device is realized by the second driving component, thereby realizing the simultaneous compaction of soil on the working surfaces at two different angles, avoiding the need for workers to continuously rotate the driving arm to adapt to the compacting working surface, and improving the efficiency of the compaction operation.
