When in use, the spraying position and direction of the high-pressure nozzle 36 can be conveniently adjusted through the telescopic hose 22, and continuous spraying can be achieved at the same time; when the spraying distance is far, the pull rod 5 is pulled, and the universal wheel 6 can drive the liquid storage tank 9 to start moving. The height of the liquid storage tank 9 can be adjusted in real time through the electric lifting rod 2, thereby effectively increasing the spraying range and realizing all-round continuous spraying of the wall to avoid color difference.
[0034] When the driving shaft 42 rotates, the driving wheel 44 starts to rotate, so that the driven wheel 46 meshed with the driving wheel 44 through the transmission belt 45 starts to rotate. When the driven wheel 46 rotates, the driven shaft 48 inside the wind tube 47 starts to rotate. When the driven shaft 48 rotates, the driven blades 49 on the side wall start to rotate, generating wind force. The wind force flows out along the air outlet 37. When spraying, the high-pressure nozzle 36 is located at the rear side of the movement direction of the spraying seat 25, so that the dust on the wall surface can be blown up during spraying to clean the wall. When the driven shaft 48 rotates, the driven blades 49 on the side wall start to rotate, generating wind force. The wind force flows out along the air outlet 37. When spraying, the high-pressure nozzle 36 is located at the rear side of the movement direction of the spraying seat 25, so that the dust on the wall surface can be blown up during spraying to clean the wall. The movable cam 50 starts to rotate. When the cam 50 rotates, it drives the push rod 54 abutting against it to move periodically along the axial direction. At this time, the second telescopic rod 52 periodically expands and contracts under the elastic force of the second spring 53, so that the connecting plate 51 moves accordingly. When the connecting plate 51 moves, it drives the slider 55 to slide periodically in the slide groove 39, so that the cleaning brush 38 on the outside of the slider 55 swings on the wall during spraying, and the wall is further cleaned. In this way, multi-stage cleaning can be achieved on the wall to be sprayed, and dust and debris on the wall can be prevented from affecting the spraying effect.
[0035] When the turbine shaft 20 rotates, it drives the driving bevel gear 31 to start rotating. When the driving bevel gear 31 rotates, it drives the driven bevel gear 32 meshing with it to start rotating, so that the transmission shaft 33 starts to rotate. When the transmission shaft 33 rotates, it drives the driving gear 34 on its top to start rotating. When the driving gear 34 rotates, it drives the driven gear 29 meshing with it through the transmission chain 35 to start rotating. When the driven gear 29 rotates, it drives the stirring shaft 26 to start rotating, so that the stirring rod 27 on the side wall of the stirring shaft 26 starts to rotate, and the paint is stirred to prevent the paint from condensing during the spraying process. When the stirring rod 27 rotates, it drives the scraper 28 to start rotating, which can scrape the paint on the inner wall of the liquid storage tank 9 to reduce waste. During stirring, the clamping block 13 can clamp and fix the liquid storage tank 9 under the elastic force of the first spring 12, thereby improving the stability of the liquid storage tank 9 during stirring.
