[0002] When the road surface is laid, it is necessary to ram the paving materials of the road surface. When the common ramming device is used, the compaction mechanism needs to move up and down to impact the materials. When the compaction mechanism moves upward, due to inertia, its own buffering is not obtained, which will affect the stability. And when it moves downward and hits a hard object, the lack of buffering will also affect the overall stability.

[0003] Therefore, those skilled in the art provide a ramming device for highway construction to solve the problems put forward. Content of the Utility Model

A plurality of inner grooves are evenly opened at the bottom of the moving block. A plug post is movably inserted at the bottom of the inner groove. A pressing plate is fixedly installed at the bottom of the plug post. Two springs are arranged in the inner groove. One spring is sleeved on the plug post, and the other spring is located between the top of the plug post and the inner wall of the top of the inner groove. By starting the motor, the moving block can be driven to move downward, and the paving road surface can be vibrated and rammed through the pressing plate.

[0007] Preferably, a plurality of threaded posts are symmetrically fixedly installed on the top of the pressing plate. The plurality of threaded posts respectively penetrate through the plurality of plug posts and are installed with nuts through threads, so as to position and install the pressing plate.
