Abstract

The invention discloses spraying equipment for propaganda slogans. The spraying equipment comprises a base, a mechanical arm is installed at the upper end of the base, a spraying mechanism for replacing and spraying paint is arranged on the base, the spraying mechanism comprises a supporting plate fixedly connected to the upper end of the base, a fixing block is fixedly connected to the upper end of the supporting plate, a circular cavity is formed in the fixing block, a conveying disc is rotationally connected to the inner wall of the circular cavity in a sealed mode, a first conveying pipeline and a second conveying pipeline are symmetrically arranged in the conveying disc, a feeding pipe is in threaded connection with the top of the circular cavity, a motor for driving the circular cavity to rotate is installed on the side wall of the fixing block, a collecting cover is installed on the side wall of the mechanical arm, and a circular ring is fixedly connected to the side wall of the collecting cover. By arranging the spraying mechanism and a control mechanism, a paint spraying pipe can be quickly replaced when different paints are sprayed on the wall surface, and compared with the prior art, the spraying can be carried out without firstly cleaning a nozzle, so that the spraying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of spraying equipment, in particular to a spraying equipment for slogans. Background technique [0002] At present, propaganda slogans are often sprayed on the surface of the street wall by spraying equipment to provide the latest information for passing pedestrians.

Problems solved by technology

[0004] 1. In order to be eye-catching, the slogan needs to be sprayed with different colors of paint, which leads to the need to clean the nozzle before spraying when changing the paint, which leads to the spraying of the wall interruption, reducing its efficiency;

[0005] 2. After the nozzle is treated with water, there will be residual moisture in the nozzle and the paint delivery pipe, so that the subsequent paint will be mixed with water when it is sprayed, which will reduce the adhesion of the paint and affect the appearance of the wall after spraying quality
