[0002] Road compaction equipment is a tool used to compact and densify the road surface. It is mainly used to ensure the stability and durability of the road structure. It improves the bearing capacity, anti-sinking and durability of the road surface by applying pressure. They play a key role in road construction and maintenance to ensure that the road is smooth, stable and safe.

[0003] After searching, in the road surface compacting equipment for filling roadbed with publication number CN213114198U, the utility model discloses a road surface compacting equipment for filling roadbed, including a base plate, a moving wheel is fixedly installed on one side of the bottom of the base plate, and an electric hydraulic rod is fixedly installed on the top of the base plate, a fixed block is fixedly installed on the top of the electric hydraulic rod, and a hollow box is fixedly installed on the back of the fixed block, a pushing frame is fixedly installed on the top of the hollow box, a connecting block is movably sleeved on one side of the hollow box, and a fixed frame is fixedly installed on one side of the connecting block, a rotating rod is fixedly sleeved on one side of the front of the fixed frame, and a flattening cylinder is rotatably connected to the middle part of the outer surface of the rotating rod. The road surface compacting equipment for filling roadbed, through the mutual cooperation between the flattening cylinder, the controller, the vibrating rod and the connecting plate, facilitates better flattening and compacting of the road surface, thereby solving the problem of high operating difficulty and poor compacting effect of the compacting equipment in the process of flattening and compacting the road surface, thereby improving the practicability of the compacting equipment.

[0004] General road compaction equipment has the following problems:

[0005] General road compaction equipment does not have a related soil paving structure, and only compacts the road surface through a compaction roller. Due to the unevenness of the road surface, the compacted road surface is bumpy and uneven, and a relatively good flattening effect cannot be achieved on the road surface. In addition, most road compaction equipment cannot scrape the soil adhered to the surface of the compaction roller in time, causing the soil adhered to the surface of the compaction roller to accumulate more and more, thus affecting the normal use of the equipment. To this end, we propose a road compaction equipment. Utility Model Content
