A placing seat 1.6 is rotatably arranged at the upper end of the support rod 1.5. A first motor 1.7 is also fixedly connected to the upper side wall of the lifting plate 1.4. An eccentric rod 1.8 is fixedly connected to the output shaft end of the first motor 1.7. A sliding groove is formed in the lower side wall of the placing seat 1.6. A connecting shaft is slidably arranged in the sliding groove. The other end of the eccentric rod 1.8 is rotatably connected to the connecting shaft. A spraying gun 1.9 is arranged on the placing seat 1.6. The input end of the material pump 1.2 is communicated with the inside of the storage bucket 1.1 through a material pipe, and the output end is communicated with the spraying gun 1.9 through a material pipe. A cleaning assembly 2 is arranged on the storage bucket 1.1. A positioning assembly 3 is also arranged on the placing seat 1.6. The material pump 1.2 can pump out the paint in the storage bucket 1.1 and transport it into the spraying gun 1.9. The spraying gun 1.9 sprays the paint onto the wall. During the spraying process, the output shaft of the first motor 1.7 drives the eccentric rod 1.8 to rotate. When the eccentric rod 1.8 rotates, the connecting shaft slides in the sliding groove at the bottom of the placing seat 1.6, causing the placing seat 1.6 to swing reciprocally under the support of the support rod 1.5, increasing the spraying range. The telescopic end of the cylinder 1.3 can push the lifting plate 1.4 to move upward, further increasing the spraying range.

[0026] Specifically, as Figure 3As shown in the figure, for the spraying device used in decoration projects, the cleaning component 2 includes an L-shaped bracket 2.1, a hollow ring 2.2, a second motor 2.3, a first screw rod 2.4, a push rod 2.5, a telescopic rod 2.6, a scraper 2.7 and a high-pressure nozzle 2.8. Two symmetrically distributed L-shaped brackets 2.1 are fixedly connected to the outer side wall of the storage barrel 1.1. A hollow ring 2.2 is arranged inside the storage barrel 1.1. A second motor 2.3 is fixedly connected to the upper outer wall of one of the L-shaped brackets 2.1. The output shaft end of the second motor 2.3 passes through the upper side wall of the L-shaped bracket 2.1 and is fixedly connected to a first screw rod 2.4. A push rod 2.5 is sleeved on the outer side of the first screw rod 2.4 in a threaded manner. The bottom end of the push rod 2.5 is fixedly connected to the hollow ring 2.2. A scraper 2.7 is fixedly sleeved on the outer side of the hollow ring 2.2. A plurality of high-pressure nozzles 2.8 are arranged in a ring on the bottom wall of the hollow ring 2.2. A telescopic rod 2.6 is fixedly connected to the upper inner wall of the other L-shaped bracket 2.1. The telescopic end of the telescopic rod 2.6 is fixedly connected to the hollow ring 2.2. After the spraying is completed, the output shaft of the second motor 2.3 can drive the first screw rod 2.4 to rotate. When the first screw rod 2.4 rotates, it can make the push rod 2.5 push the hollow ring 2.2 to move downward. At the same time, the telescopic end of the telescopic rod 2.6 follows and extends, making the hollow ring 2.2 move more stably when moving. The downward movement of the hollow ring 2.2 drives the scraper 2.7 and the high-pressure nozzle 2.8 to move downward. The scraper 2.7 scrapes and cleans the inner wall of the storage barrel 1.1, scraping off the paint that has not been washed down by the high-pressure nozzle 2.8.

[0027] Specifically, as Figure 4 As shown in the figure, for the spraying device used in decoration projects, the positioning component 3 includes a U-shaped frame 3.1, a threaded hole 3.2, a second screw rod 3.3, a pressing block 3.4 and a handwheel 3.5. A U-shaped frame 3.1 is fixedly arranged on the placing seat 1.6. A threaded hole 3.2 is opened on the upper side wall of the U-shaped frame 3.1. A second screw rod 3.3 is threadedly connected in the threaded hole 3.2. A pressing block 3.4 is slidably arranged between the front and rear inner walls of the U-shaped frame 3.1. The upper end of the second screw rod 3.3 is fixedly connected to a handwheel 3.5 and the lower end is rotatably connected to the pressing block 3.4. When the spraying encounters a dead angle, rotate the handwheel 3.5 to drive the second screw rod 3.3 to rotate. When the second screw rod 3.3 rotates, it will drive the pressing block 3.4 to move upward. At this time, the spraying gun 1.9 can be removed from the placing seat 1.6 for manual spraying. After the manual spraying is completed, put the spraying gun 1.9 into the placing seat 1.6, and then reverse the handwheel 3.5. The second screw rod 3.3 drives the pressing block 3.4 to move downward, so that the pressing block 3.4 presses and fixes the spraying gun 1.9, enabling the spraying gun 1.9 to be disassembled only as needed, making it more flexible.

[0028] Specifically, as Figure 3As shown in the figure, for the spraying device used in decoration projects, a stirring motor 1.11 is installed on the upper outer wall of the storage bucket 1.1. The output shaft of the stirring motor 1.11 extends into the storage bucket 1.1 and is fixedly connected to a rotating rod 1.12. A plurality of stirring blades 1.13 are evenly arranged on the rotating rod 1.12. The output shaft of the stirring motor 1.11 can drive the rotating rod 1.12 and the stirring blades 1.13 to rotate, so that the stirring blades 1.13 stir the paint in the storage bucket 1.1, avoid the precipitation and solidification of the paint, and improve the spraying quality.

[0029] Specifically, as Figure 1 As shown in the figure, for the spraying device used in decoration projects, a water tank 4 is fixedly arranged on the upper side wall of the trolley 1. A water pump 4.1 is installed on the water tank 4. The input end of the water pump 4.1 is connected to the water tank 4 through a water pipe and the output end is connected to the hollow ring 2.2 through a water pipe. The water pump 4.1 can pump out the water in the water tank 4 and transport it into the hollow ring 2.2.

[0030] Specifically, as Figure 3 As shown in the figure, for the spraying device used in decoration projects, a guide groove 2.11 is opened on the inner wall of one side of the L-shaped bracket 2.1 away from the storage bucket 1.1. A connecting rod 2.12 is slidably arranged in the guide groove 2.11. The other end of the connecting rod 2.12 is fixedly connected to the push rod 2.5. When the push rod 2.5 moves up and down, the connecting rod 2.12 will slide in the guide groove 2.11 to guide and limit the push rod 2.5.

[0031] Specifically, as Figure 2 As shown in the figure, for the spraying device used in decoration projects, a sewage discharge pipe 1.14 is fixedly connected to the bottom wall of the storage bucket 1.1. The sewage discharge pipe 1.14 passes through the trolley 1 and extends downward. A valve is arranged on the sewage discharge pipe 1.14. When the valve is opened, the sewage generated when cleaning the storage bucket 1.1 will be discharged through the sewage discharge pipe 1.14.

[0032] In the specific implementation of the present utility model, the coating is added into the storage barrel 1.1, and then the spraying gun 1.9 is directed at the wall to be sprayed. The material pump 1.2 pumps out the coating in the storage barrel 1.1 and transports it into the spraying gun 1.9. The spraying gun 1.9 sprays the coating onto the wall. During the spraying process, the output shaft of the first motor 1.7 drives the eccentric rod 1.8 to rotate. When the eccentric rod 1.8 rotates, the connecting shaft slides in the chute at the bottom of the placing seat 1.6, causing the placing seat 1.6 to swing reciprocally under the support of the support rod 1.5, increasing the spraying range. The telescopic end of the cylinder 1.3 can push the lifting plate 1.4 upward to further increase the spraying range. The output shaft of the stirring motor 1.11 can drive the rotating rod 1.12 and the stirring blade 1.13 to rotate, so that the stirring blade 1.13 stirs the coating in the storage barrel 1.1 to prevent the coating from precipitating and solidifying and improve the spraying quality. When spraying encounters a dead angle, the handwheel 3.5 is rotated to drive the second screw rod 3.3 to rotate. When the second screw rod 3.3 rotates, it will drive the pressing block 3.4 to move upward. At this time, the spraying gun 1.9 can be removed from the placing seat 1.6 for manual spraying. After the manual spraying is completed, the spraying gun 1.9 is placed into the placing seat 1.6, and then the handwheel 3.5 is rotated in reverse. The second screw rod 3.3 drives the pressing block 3.4 to move downward, so that the pressing block 3.4 presses and fixes the spraying gun 1.9. After the spraying is completed, the valve on the sewage discharge pipe 1.14 is opened, and then the water pump 4.1 and the second motor 2.3 are started. The water pump 4.1 pumps out the water in the water tank 4 and transports it into the hollow ring 2.2. The high-pressure nozzle 2.8 sprays the water onto the inner wall of the storage barrel 1.1. The output shaft of the second motor 2.3 can drive the first screw rod 2.4 to rotate. When the first screw rod 2.4 rotates, it can make the push rod 2.5 push the hollow ring 2.2 to move downward. At the same time, the telescopic end of the telescopic rod 2.6 follows and extends, making the hollow ring 2.2 move more stably when moving. The downward movement of the hollow ring 2.2 drives the scraping plate 2.7 and the high-pressure nozzle 2.8 to move downward. The scraping plate 2.7 scrapes the inner wall of the storage barrel 1.1 to scrape off the coating that has not been washed down by the high-pressure nozzle 2.8, and the sewage will be discharged through the sewage discharge pipe 1.14.
