Paint sprayer for building

Abstract

The invention discloses a paint sprayer for a building in the technical field of buildings. The paint sprayer comprises a bottom plate, wherein a storage box is arranged in the center of the top of the bottom plate; an output end at the bottom of a drive motor extends to an inner chamber of the storage box and is connected with a stirring rod; a delivery pump is arranged on the right side of the bottom of the inner chamber of the storage box; a brush main body is arranged at the end, away from the storage box, of a hose; brush rollers are arranged on upper and lower sides of the right end of the brush main body; a support pipe is arranged in the center of the right end of the brush main body; the hose penetrates the brush main body and is connected with the support pipe; nozzles are uniformly arranged on the outer wall of the support pipe; a telescopic device is arranged at the bottom of the brush main body. By means of the nozzles uniformly arranged on the surface of the support pipe,on one hand, paint is provided continuously for the brush rollers, and non-uniform paint caused by absence of the paint on the brush rollers is prevented; on the other hand, the paint is sprayed to awall, and influence on quality of wall paint by non-uniform painting due to too little paint is prevented.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a paint spraying machine for construction. Background technique [0002] Coatings, traditionally called paints in China, are coatings on the surface of objects to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion. Adding or not adding pigments, fillers, adding corresponding additives, viscous liquid prepared with organic solvents or water, coatings are widely used in architectural decoration, for beautifying and protecting walls, existing artificial coatings When spraying the wall, first dip the painting tool into the paint, and then dip the painting tool into the paint when the paint is used up, and repeat the process to paint, which will easily cause uneven painting, and when the wall is too high , the top cannot be painted evenly, resulting in low quality of painting and reducing...
