Technical Field

The utility model relates to the technical field of rollers for road rollers, in particular to a roller for road rollers.

Background Art

A road roller, also known as a soil compactor, is a piece of road construction equipment. It belongs to the category of road equipment among engineering machinery and is widely used in filling and compacting operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. It can compact sandy, semi-viscous and viscous soils, roadbed stabilized soils, and asphalt concrete pavement layers. The road roller uses the gravity of the machine itself and is suitable for various compaction operations, making the compacted layer permanently deformed and dense.

After searching, it was found that the "A roller for a road roller" disclosed in Chinese patent publication number CN219637620U includes a square frame, a connecting block is welded on the right side of the square frame, a connecting plate is welded on the right side of the connecting block, and the connecting plate is connected to the road roller by bolts, a cleaning plate is inserted on the left side of the square frame, a collar is fixedly inserted inside the cleaning plate, an adjusting rod is threadedly connected to the inside of the collar, two groups of stabilizing blocks are welded on the inner wall of the square frame, a roller is arranged inside the square frame, and a fixed A fixed rod, both ends of the fixed rod are inserted with a splicing rod, the outer end of the splicing rod is sleeved with a limit sleeve, and the bolt passes through the limit sleeve and is screwed into the interior of the square frame; the roller used for the road roller can scrape the soil sticking on the roller through the cleaning plate, so as to prevent the roller from carrying too much soil, resulting in a reduced compaction effect, thereby improving the soil compaction effect of the roller, and the spacing distance between the cleaning plate and the roller can be adjusted by rotating the adjusting rod in the inner thread of the collar, so that the device can clean rollers of different diameters, thereby improving the scope of application and practicality of the device;
