Technical Field

[0001] The utility model belongs to the technical field of oil-spraying anti-sticking wheels for road rollers, and particularly relates to an oil-spraying anti-sticking wheel device for road rollers. Background Art

[0002] Road rollers, considered a type of construction machinery, are widely used for fill and compaction operations on large-scale projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can compact sandy, semi-cohesive, and cohesive soils, stabilized roadbed soils, and asphalt concrete pavement layers. Using the force of gravity, rollers are suitable for various compaction operations, creating permanent deformation and densification of the compacted layer. Road rollers are categorized as either steel-wheeled or tire-type. Current front wheels on rollers are prone to oil-spraying during use, making them difficult to repair. Therefore, we propose an oil-spraying anti-sticking wheel device for rollers.

At the same time, the oil sprayed on the surface is prone to accumulation when scraping. At the same time, the distance between the anti-sticking wheel device and the front wheel of the roller is inconvenient to adjust, which affects the working efficiency of the roller.
