Movable slot sprayer

Abstract

The invention relates to the technical field of spraying, in particular to a movable narrow slit spraying device which can movably spray on narrow slits. The movable narrow slit spraying device is used for spraying paint on the narrow slits and comprises a vehicle body, wherein the vehicle body is provided with wheels and a spray gun used for spraying. According to the movable narrow slit spraying device, the wheels extend and are placed into the narrow slits, and the wheels only make contact with the edges or the exteriors of the narrow slits and can move along the narrow slits; a nozzle of the spray gun extends into the narrow slits for direct and efficient spraying, and meanwhile the wheels extend and are placed into the narrow slits, so that the device stably moves along the narrow slits and evenly sprays the paint on the narrow slits in the moving process. According to the structure, while the device stably moves, tracks matched with the wheels are omitted, and the movable narrow slit spraying device is simple in structure and convenient to use, effectively reduces the cost, is beneficial to achieving long-distance control and avoids the problem that the health of constructors is affected because primer is sprayed manually.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a movable slit spraying device for movable spraying of slits. Background technique [0002] In order to avoid cracking and other damage caused by thermal expansion and contraction of the base material, and to facilitate the operability of the construction, the outdoor building surface is often equipped with reserved seams or cut seams, and the seams are treated with sealant caulking technology. However, in order to prolong the service life of the sealant in actual engineering, the industry practice is usually to paint the primer in the joint to enhance the strength of the bonding interface and improve the bonding effect. The current primer construction method is to use a brush to dip the primer into the seam and brush it into the joint. Due to the strong irritation of the primer, the poor brushing effect, and the large amount of construction joints, the primer is applied manuall...

Problems solved by technology

The current primer construction method is to use a brush to dip the primer into the seam and brush it into the joint. Due to the strong irritation of the primer, the poor brushing effect, and the large amount of construction joints, the primer is applied manually. Not only will it affect the health of construction workers, but it will also affect the quality of construction joints and construction efficiency
