Technical Problem

[0003]在中国专利公开号为CN220889313U中公开的一种施工墙体防水喷涂装置，该施工墙体防水喷涂装置，利用高压柱塞泵将涂料增压，获得高压的涂料通过高压软管输送到喷枪，经由喷嘴释放压力形成雾化，从而在墙体表面形成致密的涂层；但根据相关领域提供的喷涂装置以及现有技术，传统装置多采用固定喷嘴或单一喷幅设计，面对大面积平整区域、边角、管线周围以及墙角点位时，易因范围过大导致边缘区域涂料堆积或浪费，从而需频繁更换喷嘴或调整设备位置，导致施工中断

Benefits of technology

[0011] The beneficial effects of this wall spraying device for building construction are as follows: by setting up guide plates and adjustment components, it can quickly switch between wide-width spraying, narrow-width spraying and spot spraying, meeting different construction needs such as large-area walls, corner areas, and irregular structures. It eliminates the need to frequently change nozzles or spray guns, improving construction flexibility and ensuring uniform material output under different spraying modes, thus avoiding situations where the coating is too thick or too thin in some areas.

Abstract

The utility model relates to the field of building construction technology, concretely is a kind of wall spraying device for building construction, including spray gun and spraying machine, the gun barrel end of spray gun is equipped with nozzle, two guide plates for changing spray material state are symmetrically arranged in the inside of nozzle, the tail end of two guide plates is all spline coupling with spline shaft, two spline shafts are all rotationally connected with the nozzle, the top of nozzle is fixedly installed with cover plate, adjusting assembly for controlling the opposite rotation of two spline shafts is equipped on the cover plate;By setting guide plate and adjusting assembly, the effect that wide spraying, narrow spraying and point spraying can be quickly switched is achieved, different construction needs such as large-area wall surface, corner area, special-shaped structure are satisfied, nozzle or spray gun need not be frequently replaced, construction flexibility is improved, so that the uniformity of discharge under different spraying modes can be guaranteed, and the situation that local coating is too thick or too thin is avoided.
