[0016] 1. When the walking wheels are connected with the road, power is transmitted to the transmission assembly, the transmission assembly drives the reciprocating ramming assembly to perform static pressure treatment on the constructed road surface, and the two groups of pre-pressing assemblies are distributed on the two sides of the reciprocating ramming assembly, which is used to adjust the ramming strength of the two groups of pre-pressing assemblies according to the ramming characteristics of the road surface from light to heavy, prevent the composite ramming of the constructed road surface, and ensure the strength of the road surface, thereby improving the ramming quality of the road.

[0017] 2. The first static pressure roller, the second static pressure roller and the third static pressure roller rotate around the linkage rod, in the switching process of each group of static pressure rollers, the linkage rod is synchronously lifted, the linkage wheel increases the contact area between the linkage rod and the extrusion plate, the two ends of the linkage rod extrude the second spring on the extrusion plate in the lifting process, and the tension of the spring can be used to reset the static pressure roller after switching and also can be used to apply the pressure to the static pressure roller after switching, thereby strengthening the static pressure ramming degree of the road.

[0018] 3. The servo motor can be lifted with the linkage rod to adjust the displacement of each group of static pressure rollers after switching, and the output end of the servo motor can drive the linkage rod to rotate, so that the four groups of walking wheels are synchronously rotated in the synchronous rotation process of the first transmission rod and the second transmission rod, thereby facilitating the use of the ramming equipment in manual or electric driving environment.
