Abstract

This utility model discloses a concrete pavement smoothness control device, belonging to the field of pavement smoothness construction technology. It includes a vibratory screed, with a pouring baffle on one side and a leveling guide mechanism on the outer side of the pouring baffle. The leveling guide mechanism includes a tilting crossbeam, a tilting seat, a lifting assembly, and a guide wheel. The tilting seat is located on one side of the pouring baffle, and the tilting crossbeam is rotatably connected to the tilting seat. This utility model provides a straight running trajectory for the guide wheel through a guide rail, accurately guiding the vibratory screed, effectively reducing the deviation of the screed's running angle, significantly improving pavement smoothness, and ensuring construction quality. By combining the leveling operation of the vibratory screed with the pouring baffle and the leveling guide mechanism, the leveling operation is made more standardized, reducing reliance on operator experience, alleviating the workload and difficulty of manual, disorderly leveling, and improving construction efficiency.
