AI Technical Summary

Technical Problem

In existing automated spraying and plastering equipment for construction and civil engineering, mortar tends to get stuck in the plastering slabs during the plastering process, affecting the spraying effect. Furthermore, it is difficult to adjust the tilt angle and thickness of the plastering slabs when they are perpendicular to the wall, resulting in mortar waste and reduced adhesion.

Method used

A device comprising a frame, a support, a spray nozzle, and a plastering assembly is designed. The plastering assembly consists of a plastering board, a through groove, and a guide groove. The tilt angle and distance of the plastering board are adjusted by an electric push rod, and excess mortar is collected by the through groove and the guide groove. Combined with a servo motor and a booster pump, efficient spraying and collection of mortar are achieved.

Benefits of technology

It achieves efficient mortar spraying and collection, reducing waste and pollution. It can flexibly adjust the angle and position of the plastering board according to different needs, ensuring uniform mortar adhesion and improving spraying effect and adhesion.
