[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 In an embodiment of the utility model, a waterproof construction device for a subway decoration and renovation wall ditch includes a body 3, two threaded plates 12 are provided below the body 3, and a distance adjustment mechanism for adjusting the distance between the two threaded plates 12 is installed on the body 3, a blowing mechanism 2 is installed on the body 3, and the blowing mechanism 2 includes a blower 201 provided on the surface of the body 3, and a blowing pipe 202 connected to the lower end surfaces of the two threaded plates 12, the two blowing pipes 202 are connected to the blower 201, and the lower end surfaces of the two threaded plates 12 are installed with mounting frames 204, and the opposite sides of the two mounting frames 204 are installed with cleaning hair rollers 203.

[0028] Specifically, the two parallel threaded plates 12 can be adjusted to a suitable position by the distance adjustment mechanism, so that the two threaded plates 12 can adapt to the wall grooves of different widths. Secondly, the blower 201 is fixedly installed on the upper surface of the vehicle body 3, and a hose is installed at its air outlet, and the other end of the hose is connected to the two blowing pipes 202 respectively. The opposite sides of the two blowing pipes 202 are provided with a plurality of air outlets, so that the air generated by the blower 201 can be transported to the blowing pipe 202 through the hose, and the air is blown out from the air outlets on the two blowing pipes 202. While cleaning the dust and other impurities adhered to the inner wall, the cleaning roller 203 rotates to clean the inner wall of the wall groove again to ensure the cleanliness of the inner wall of the wall groove. Although the two cleaning rollers 203 and the two blowing tubes 202 are all installed on the threaded plate 12, the spacing between the two cleaning rollers 203 is always greater than the spacing between the two blowing tubes 202. In this way, when the cleaning roller 203 contacts the inner wall of the wall groove, there is still a certain distance between the blowing tube 202 and the inner wall of the wall groove, which can ensure that the air in the blowing tube 202 is blown out from the air outlet smoothly, thereby ensuring its best blowing effect.

[0029] See also Figure 1 In one embodiment, in this embodiment, preferably, a paint pump 6 and a paint tank 9 are respectively installed on the upper end surface of the vehicle body 3, and the input end of the paint pump 6 is connected to the paint tank 9, and the output end of the paint pump 6 is connected to the two spray pipes 5 through a hose.

The stirring blades 105 with through holes and distributed at equal angles can be used to more efficiently stir the waterproof coating inside the coating tank 9, thereby reducing the precipitation of the waterproof coating inside the coating tank 9. A scraper 106 for scraping the inner wall of the coating tank 9 cavity is also installed on the surface of the stirring rod 109, and the cross-section of the scraper 106 is inverted L-shaped. By using the inverted L-shaped scraper 106, the rotation of the stirring rod 109 will drive the scraper 106 to rotate to scrape and clean the inner wall of the coating tank 9, thereby reducing the residue of waterproof coating on the inner wall of the coating tank 9.

[0036] Specifically, the driving motor 107 drives the stirring blade 105 and the scraper 106 located in the paint tank 9 to rotate through the stirring rod 109, and stirs the waterproof coating inside respectively. While the stirring blade 105 and the scraper 106 stir the waterproof coating, the electric push rod 102 located on the fixed frame 101 drives the driving motor 107 and the stirring rod 109 to move up and down, so as to prevent the waterproof coating from settling inside the paint tank 9 and affecting the waterproof quality after subsequent spraying.
