[0002] A road roller, also known as a soil compactor, is a road construction equipment widely used for filling and compaction operations in large engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. It compacts the ground through components such as heavy hammers and tires, causing the rolled layer to be permanently deformed and dense. The working principle of a road roller involves the free-fall impact of the heavy hammer and the vibration force generated by the vibration device to improve the compaction effect.

[0003] During the construction process of the existing roller, when the driver operates the roller, the front steel wheel blocks the driver's line of sight, resulting in a partial blind spot during driving. The driver cannot find obstacles on the ground in time.
