When carrying out road construction, it is necessary to use gravel laying equipment to lay gravel on the foundation.

[0003] The prior art patent document with publication number CN217601138U provides a gravel paving device for road construction, comprising: a base plate, a walking track is installed at the bottom of the base plate, and a box frame is fixedly installed on the base plate; a gravel leveling component, the gravel leveling component is arranged on one side of the box frame, and is used for leveling and paving the gravel; a blanking component, the blanking component is arranged in the box frame on one side of the gravel leveling component, and is used for mixing and blanking the gravel for paving; the device is convenient for mixing and stirring the sand and gravel, and the mixed sand and gravel can be laid on the road and the sand and gravel can be leveled, so that the working efficiency of the gravel paving is high.

[0004] However, during the use of the existing road construction gravel layer paving device, the outflow of sand and gravel cannot be accurately controlled during the paving process. When the sand and gravel fall to the ground, they will pile up. Due to the different paving thicknesses and different amounts of sand and gravel flowing out, the excess sand and gravel cannot be picked up and laid to a smaller position during the leveling process, resulting in the need for manual filling by staff after paving, which increases the workload of staff and affects the paving efficiency. For this reason, we propose a precise paving device for road construction gravel layers. Utility Model Content
