AI Technical Summary

Technical Problem

During the process of paving asphalt with shovels, the asphalt material is difficult to fall off quickly due to its high adhesion, resulting in low paving efficiency. Commonly used oily lubricants will cause the pavement to be dispersed and affect the service life.

Method used

A bitumen paving shovel was designed, and its shovel board was covered with a low friction coefficient material layer, and it was fixed on the shovel board with polytetrafluoroethylene, polyurethane or polyethylene board, combined with epoxy resin glue or acrylic glue to form a slope-shaped low friction coefficient material layer.

Benefits of technology

Through the design of the low friction coefficient material layer, asphalt materials are not easy to stick during paving, and can quickly break away from the shovel, which improves paving efficiency, reduces the risk of pavement dispersion, and extends the service life of the pavement.

Abstract

The utility model discloses an asphalt paving shovel. The shovel comprises a shovel plate, a shovel handle and a low-friction-coefficient material layer. Wherein a sleeve is arranged in the middle of the upper end of the shovel plate, and the lower end of the shovel handle is fixed in the sleeve; the front face and the back face of the shovel plate are each provided with a low-friction-coefficient material layer in an overlapped mode The asphalt paving spade provided by the utility model has the beneficial effects that the characteristics that the low-friction-coefficient material is not adhered to asphalt and can tolerate high temperature in the asphalt paving process are fully exerted, so that the asphalt can be quickly separated from the spade in the asphalt paving process by using the spade; besides, the shovel plate can be detached and replaced, the functional requirements of short-distance carrying, cleaning and shoveling, flat cutting and the like of the shovel in the asphalt paving process are met, the asphalt paving efficiency is improved, and certain economic benefits and social benefits are achieved.
