Pressing wheel vehicle wheel for pavement sand paving

Abstract

The invention relates to the technical field of traffic, and discloses a pressing wheel vehicle wheel for pavement sand paving. The pressing wheel vehicle wheel comprises a pressing wheel cover body and two connecting plates, an inner cylinder and a solid pressing wheel are arranged in the pressing wheel cover body, an inner storage tank is formed in the pressing wheel cover body, short columns are fixedly installed on the two walls in the inner storage tank, and supporting mechanisms are arranged below the two short columns; a flattening and screening mechanism is arranged between the two supporting mechanisms, the supporting mechanisms and the flattening and screening mechanism are arranged to matched an impacting mechanism, sand is thrown into the flattening and screening mechanism while the pressing wheel cover body moves, and the impacting mechanism is driven by gravity change generated by rotation of the inner cylinder to vibrate and screen the sand in the flattening and screening mechanism. After sand is screened, the sand is flatly spread and falls onto a cement road surface, and then the sand is flattened onto the cement road surface by the solid pressing wheel, so that multiple operation steps of the sand are reduced, the sand paving process is simplified, the phenomenon of compression accumulation caused by the sand is avoided, and the flatness of the sand paved on the cement road surface is effectively improved.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a roller wheel for paving sand on roads. Background technique [0002] Due to the long-term exposure of the traffic road surface, the road surface needs to be repaired or damaged frequently. At present, the road surface used for auxiliary roads is mostly constructed with cement, and the cement road surface needs to be covered with sand when the construction is completed to prevent the time of cement slurry extraction. Too late, resulting in peeling and sanding on the surface of the cement pavement. [0003] At present, after the cement pavement is built, the sand is directly dumped on the cement pavement first, and then the sand is pressed on the cement pavement by a roller truck. This method not only requires multiple operations, is time-consuming and laborious, but also makes the sand It causes compression and accumulation at the initial location, which is not conducive to the...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a roller wheel for paving sand, which not only reduces the multiple operation steps of sand, simplifies the process of sand paving, but also avoids the phenomenon of sand being compressed and piled up, effectively It has the advantages of improving the flatness of the sand paving and cement pavement, and solves most of the existing methods. Not only does it require multiple operations, it is time-consuming and laborious, but it will also cause the sand to be compressed and accumulated at the initial location, which is not conducive to the smooth paving of the sand.
