[0002] A road roller, also known as a soil roller, is a type of road construction equipment, which is divided into two categories: steel wheel type and tire type. Among construction machinery, road rollers belong to the category of road equipment and are widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can compact sandy, semi-sticky and sticky soils, roadbed stabilized soil, and asphalt concrete pavement layers. The road roller uses the gravity of the machine itself and is suitable for various compaction operations, causing the compacted layer to undergo permanent deformation and become dense. During the construction process of the road roller, mud, asphalt, concrete and other debris will adhere to the surface of the roller wheel, which can easily cause an uneven road surface. Existing equipment is usually equipped with a shovel plate for scraping and cleaning, but the shovel plate is currently usually installed and fixed with multiple bolts, which makes the disassembly and assembly operations cumbersome and inconvenient for maintenance or replacement.
