Description

Technical Field

[0001] The utility model relates to the technical field of road surface polishing, in particular to a polishing machine for cement concrete road surface construction. Background Art

[0002] As we all know, trowels are often used in the process of road construction. Trowels are also called finishing machines. Their main structure is a trowel rotor driven by a gasoline engine. A trowel is installed on the bottom of the cross in the middle of the rotor. The inclination direction of the trowel is consistent with the rotation direction of the rotor. The gasoline engine drives the V-belt to rotate the trowel rotor. However, when the existing trowel is used to polish the courtyard and other places, it is impossible to polish the cement concrete in the dead corners.

[0003] After searching, the utility model patent with Chinese publication number CN218711988U discloses a trowel for permeable concrete pavement construction, which includes a concrete construction trowel body, the concrete construction trowel body includes a telescopic overlapping platform, the telescopic overlapping platform includes a concrete water stain scraper, and an overlapping sleeve is fixedly connected to the bottom outer surface of the telescopic overlapping platform on the left side, the overlapping sleeve includes a concrete rolling and smoothing mechanism, and the concrete rolling and smoothing mechanism includes an overlapping strip. The utility model cooperates with the rotator to rotate the overlapping strip, and the bottom surface of the overlapping strip is overlapped on the concrete surface, and the arc-shaped rolling groove on the outer surface of one side of the overlapping strip is used to slide and overlap on the surface of the concrete to smooth the concrete, and at the same time cooperates with the rolling and smoothing strip on the right outer surface of the trapezoidal hollow elastic strip to elastically extrude the smoothed concrete, softly fit it, and roll and compact some loose concrete.

[0004] Although the above technical solution solves the problem of rolling and compacting the smoothed concrete, in the above technical solution, the concrete construction smoothing device body and the overlapping sleeve connected thereto are both circular. When facing ground treatment work in courtyards and other places, it is impossible to smooth the dead corners, and manpower is still needed for subsequent treatment, which not only wastes manpower and material resources, but also delays the workers' working time. Therefore, a smoothing machine for permeable concrete pavement construction is needed. Utility Model Content
