[0002] Vibratory rollers have powerful exciting force and high static linear pressure. They are suitable for compacting base layers, sub-base layers and fills of various materials. They are ideal compaction equipment for building high-grade highways, airports, ports, dams and industrial construction sites.

[0003] When the roller of the existing single-steel-wheel vibratory roller is compacting the road surface, the mud and sand on the road surface will adhere to the roller, resulting in reduced quality of the subsequent compaction work of the roller on the road surface, making the road surface uneven. In addition, the structure of the existing single-steel-wheel vibratory roller is relatively fixed, and it is not convenient to adjust the vertical height of the roller. The pressure of the roller is adjusted according to the road surface conditions. For this reason, we propose a single-steel-wheel vibratory roller. Utility Model Content
