TECHNICAL FIELD

[0001] The application relates to the technical field of road rollers, in particular to a road roller edge cutting and pressing device. BACKGROUND

[0002] The road roller edge cutting and pressing device is an auxiliary device for road construction, mainly used for compacting road edges and narrow areas. It is attached to a road roller to accurately compact the road edges, improve construction quality, effectively prevent the road base edges from being loose, and enhance the stability and durability of the road.

[0003] The existing Chinese public patent (authorization announcement number: CN216739138U) discloses a double-steel-wheel road roller edge cutting and pressing device. The device includes a road roller body, a roller barrel arranged on one side of the road roller body, a connecting frame arranged on the top of the roller barrel, a base arranged on the outer surface of the connecting frame, an installation plate arranged on the bottom of the base, a support frame arranged on the outer surface of the installation plate, a movable arm arranged on the side of the support frame away from the installation plate, and a movable shaft arranged on the side of the movable arm adjacent to the support frame. The double-steel-wheel road roller edge cutting and pressing device uses the support frame, the movable arm, and the hydraulic rod in cooperation to enable the operator to control the contraction of the hydraulic rod, so that the pressing wheel moves downward until it contacts the ground, thereby realizing the edge cutting and bevel pressing work of the pressing wheel, and enabling the operator to control the expansion of the hydraulic rod to store the pressing wheel, thereby effectively reducing the impact of the pressing wheel on the work of the road roller.

[0004] In the above-mentioned patent, the contraction of the hydraulic rod causes the pressing wheel to move downward until it contacts the ground, thereby realizing the edge cutting and bevel pressing work of the pressing wheel. However, in actual use, when the pressing wheel cuts the asphalt on the road edge, the cutting may not be complete due to changes in vehicle speed and pressing wheel wear, which causes the cut asphalt to still be connected to the road, affecting the verticality and aesthetics of the road surface, and reducing the durability and stability of the road surface. Therefore, the application provides a road roller edge cutting and pressing device. Practical new type content

[0015] Further, the auxiliary assembly comprises a connecting block slidingly connected in the fixed block, a pressing block is fixedly connected to the bottom of the connecting block, and a scraper is fixedly connected to one end of the pressing block.

[0016] By adopting the technical scheme, the cutting edge of the road can be pressed by the pressing block after cutting, and the cutting between the removed asphalt and the cutting edge of the road can be performed again by the scraper during movement, so that the removed asphalt by the pressing wheel can be more completely separated from the road surface.

[0024] 1. This application includes a cutting component and an auxiliary component. The roller's movement and the friction between the roller and the asphalt cause the roller to rotate continuously, cutting and trimming the asphalt at the road edge. The auxiliary component then operates simultaneously to press the cut road edge and perform a secondary cut between the removed asphalt and the road edge. This ensures more thorough separation of the asphalt removed by the roller from the road surface, reducing incomplete cutting caused by variations in asphalt viscosity, vehicle speed, and roller wear.
