Description

Technical Field

[0001] The utility model relates to the technical field of road surface compaction, in particular to a road surface compaction device for road surface engineering. Background Art

[0002] Road rollers belong to the category of road equipment among engineering machinery and are widely used in filling and compaction operations of large-scale engineering projects such as highways, railways, airport runways, dams, and stadiums. Road rollers use the gravity of the machine itself to cause permanent deformation and density of the rolled layer. When existing road rollers are in use, the road asphalt is usually placed mechanically, and then the asphalt is evenly scraped on the roadbed manually. When the road roller passes over a part with a higher asphalt content, the asphalt in the lower layer of this part of the road surface will be compacted, while the part on the upper layer may form a convex hump, resulting in an uneven road surface.

[0003] The existing patent document with announcement number CN202223005594.4 discloses a road compacting device, which relates to the technical field of road rollers, including a base, a body is fixedly installed on the upper end of the base, a motor is fixedly connected to the side of the body, a connecting plate is fixedly installed on the lower end of the base, a pressure roller is rotatably connected between the connecting plates, a synchronous belt pulley is fixedly installed on the side of the pressure roller, a cylinder is fixedly installed on the upper end of the base, and a movable rod is fixedly installed on the output end of the cylinder. When the motor is turned on, the pressure roller between the connecting plates rotates to compact the road surface. During the compaction process, the cylinder is used so that the movable rod can push the V-shaped scraper downward and make it fit with the surface of the road surface. In this way, if there are bulges on the road surface compacted by the pressure roller, the V-shaped scraper on the rear side can shovel away these bulges to ensure the flatness of the road surface. In addition, when the pressure roller rolls, the scraper can scrape off the lumps on the surface of the pressure roller to remove foreign matter on its surface.

[0004] Although the above device can solve the corresponding technical problems, it is difficult for the compaction device to adjust the compaction strength when compacting the road surface, which has certain shortcomings. Utility Model Content
