Leakage problems have become widespread, and coatings are one of the common waterproof methods.

[0003] A waterproof structure coating spraying device for an underground waterproof project with the publication number of CN221714667U can adjust the angle of the spraying plate with a high degree of freedom through a three-point adjustable method. When adjusting the height position of the spraying plate, the motor is started, the motor drives the screw to rotate, and the screw drives the lifting block, the second rotating plate, the first rotating plate and the spraying plate to move up and down.

An air flow channel 39 is arranged and communicated between the conical baffle 26 and the sleeve 37. The air inlet end of the air flow channel 39 is connected to the air outlet end of the fan 32 through a hose. The air outlet end of the air flow channel 39 faces the grinding head 36 and is inclined. The internal channel of the sleeve 37 is adapted to the spraying head 12. Two dust suction pipes 40 are symmetrically arranged on both sides of the rotating rod 35 on the support seat 29.

The outlet of the dust removal channel 38 is communicated with the collection box 28 for sucking dust through an air delivery pipe 41.

[0032] In this technical solution, such as Figure 1As shown in the figure, by means of the second electric push rod 601, the lifting frame 602 and the U-shaped frame 603, the second electric push rod 601 drives the U-shaped frame 603 to move, so that the U-shaped frame 603 drives the lifting frame 602 to move up and down, conveniently adjusting the up-and-down position of the grinding head 36.

[0033] It adopts the technical solution as shown in Figure 3 and Figures 5-8 As shown in the figure. First, start the first electric push rod 4. The first electric push rod 4 will push the moving part 5 to slide back and forth along the bracket 3, so that the grinding head 36 is attached to the wall. Then start the second motor 30. The second motor 30 will drive the connecting shaft 31 to rotate. The connecting shaft 31 will drive the fan 32 and the first pulley 33 to rotate. Through belt transmission, the first pulley 33 will drive the second pulley 34 to rotate. The second pulley 34 will drive the rotating rod 35 to rotate, so that the rotating rod 35 drives the grinding head 36 to rotate, and then pre-treat the wall. When the fan 32 rotates, it will generate air flow. The air flow enters the air flow channel 39 through the hose, and then enters the conical baffle 26 from the air flow channel 39. Since the conical baffle 26 is located inside the grinding head 36, the air flow is blown from the conical baffle 26 to the ground wall surface, blowing away the dust attached to the wall surface. Then start the air pump. Through the suction force generated by the air pump, the dust suction pipe 40 sucks the nearby dust into the collection box 28. Then open the valve connecting the dust suction pipe 40 and the air delivery pipe 41, so as to suck the dust in the dust removal channel 38 by means of suction force. Since the end of the rotating rod 35 is rotatably provided with a rotary joint, and the rotary joint is respectively connected to the air delivery pipe 41 and the hose connected to the air flow channel 39, when the rotating rod 35 rotates, it will not affect the air delivery pipe 41 and the hose;

[0034] During the grinding process, the second electric push rod 601 will drive the U-shaped frame 603 to move up and down, so that the U-shaped frame 603 drives the lifting frame 602 to move, and then adjusts the up-and-down position of the spraying head 12 on the connecting frame 7. Then, by starting the third electric push rod 27, the third electric push rod 27 will pull the fixing part 11, so that the fixing part 11 drives the slider 10 to slide left and right along the slot 9, thereby adjusting the left and right position of the grinding head 36. In this article, up and down, left and right, and front and back are all relative to the wall surface to be sprayed.

[0035] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Embodiment 1 and Embodiment 2.

[0036] In this technical solution, as Figure 2 shown, by setting the conical baffle 26, during the spraying process of the spray head 12, the conical baffle 26 can block the solution particles escaping into the air, preventing the particles from escaping into the air and causing air pollution.

[0037] It adopts such as Figure 2 and Figure 4In the technical solution shown in the figure, first, the first electric push rod 4 pulls the moving part 5 to move, and then uses the moving part 5 to drive the grinding head 36 to move so that it is separated from the wall. At this time, the first motor 15 is started, and the first motor 15 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the first stirring rod 17 to rotate, and then the rotating shaft 16 drives the reciprocating screw rod 24 to rotate.
