Spraying device for buildings

Abstract

The invention discloses a spraying device for buildings, and relates to the technical field of spraying equipment. The spraying device comprises a charging barrel used for containing materials and aninjection assembly which is connected with the charging barrel and used for spraying paint. The spraying device for the buildings is characterized in that a plurality of longitudinal partition platesare arranged inside the charging barrel, and the partition plates divide the charging barrel into a plurality of independent charging units used for containing the materials; the bottoms of the charging units are all provided with discharging openings; a rotary disk is arranged at the outer bottom of the charging barrel in a rotating mode, and a through hole is formed in the rotary disk; one end of the through hole is connected with the injection assembly, and the other end of the through hole communicates with one of the discharging openings in the spraying process; and a limiting assembly used for limiting rotation of the rotary disk is arranged between the rotary disk and the charging barrel. The effect of switching injection of different sorts of paint is achieved by rotating the rotary disk and a striker plate together with the limiting assembly, and the usability and working efficiency of the device are improved.

Description

technical field [0001] The invention relates to the technical field of spraying equipment, more specifically, it relates to a construction spraying device. Background technique [0002] In building construction, some coatings need to be sprayed on the wall. The functions of these coatings include waterproof and moisture-proof, colored coatings for beautiful buildings, etc.; As the degree of automation is getting higher and higher, the application of spraying production lines is becoming more and more extensive, and it has penetrated into many fields of the national economy. In the construction industry, the use of spraying devices is also increasing. The use of spraying devices can make Spray more evenly. [0003] For example, the authorized announcement number is CN206622237U, and the Chinese patent with the publication date of November 10, 2017 discloses a spraying machine for construction, including a vehicle frame, and the outer surface of the vehicle frame is connected...

Problems solved by technology

[0004] By adopting the detachable combination method, the various parts of the spraying machine can be combined together when in use, and can be dismantled and put into the folding box set on the back of the frame when not in use. It is easy to carry and use; but when spraying, some paints of different colors need to be sprayed. This solution can only be used to spray paints of a single color. Adding new paint seriously affects work efficiency
