The input end of the motor 18 is electrically connected to the output end of the control switch group 3. During the movement, the motor 18 starts to run through the control switch group 3. The output shaft of the motor 18 drives the stirring blades 17 to rotate through the output rod 16 to prevent the slurry from settling to the bottom.

[0028] The protective cover 4 has a water inlet 10 located at the rear of the right end of the water inlet. A water inlet valve is connected in series on the right side of the water inlet 10. The left end of the water inlet 10 is connected to the water outlet on the rear side of the outer arc surface of the mounting pipe 71 via a delivery hose 11. After spraying, the water inlet 10 is connected to an external high-pressure water pump, and then the water inlet valve is opened. The external high-pressure water pump injects the rinsing water into the delivery hose 11 through the water inlet 10. The rinsing water inside the delivery hose 11 enters the mounting pipe 71, and then the rinsing water inside the mounting pipe 71 enters the nozzle 2 73 through the connecting pipe 72. Finally, it is sprayed out through the nozzle 2 73 to rinse the inside of the storage tank 2.

[0029] The working principle of the anti-sticking wet spraying machine provided by this utility model is as follows: Before use, first connect the feed pipe 5 to the external pipeline, then open the feed valve and add the slurry into the storage tank 2 through the feed pipe 5. After adding, separate the feed pipe 5 from the external pipeline, close the feed valve, and then move the anti-sticking wet spraying machine to the designated working location through the external traction device. During the movement, the motor 18 starts to run through the control switch group 3. The output shaft of the motor 18 drives the stirring fan blade 17 to rotate through the output rod 16 to prevent the slurry from settling to the bottom. After moving to the designated working location, the electric push rod 19 starts to run through the control switch group 3. The telescopic end of the electric push rod 19 extends, thereby driving the... The support plate 20 moves downwards until its lower end contacts the ground, thus improving the stability of the wet spraying machine for the anti-sticking material. Then, by opening the discharge valve and delivery valve, the operator holds the nozzle 15 and aims it at the target area. The booster pump 12 starts operating through the control switch group 3. The booster pump 12 draws slurry from the storage tank 2 through the discharge pipe 13, then injects it into the nozzle 15 through the delivery pipe 14, and finally discharges it through the nozzle 15, thus spraying slurry onto the designated area. After spraying, the inlet pipe 10 is connected to an external high-pressure water pump, and the inlet valve is opened. The external high-pressure water pump injects rinsing water into the delivery hose 11 through the inlet pipe 10. The internal rinsing water enters the installation pipe 71, and then the rinsing water inside the installation pipe 71 enters the nozzle 73 through the connecting pipe 72, and finally sprays out through the nozzle 73, thereby rinsing the inside of the storage tank 2. At the same time, the booster pump 12 injects the cleaning water in the storage tank 2 into the delivery pipe 14 through the discharge pipe 13, and finally discharges it from the nozzle 15. This achieves synchronous cleaning of the discharge pipe 13, the delivery pipe 14, and the nozzle 15. During the cleaning process, the drive motor 21 starts to run through the control switch group 3. The output shaft of the drive motor 21 drives the half gear 79 to rotate. When the half gear 79 meshes with the gear 78, the gear 78 passes through the installation pipe 73. The rod 75 drives the transmission plate 76 to rotate. At this time, the horizontal plate 74 is pushed downward by the fixed rod 77, the spring 9 contracts, and the horizontal plate 74 drives the connecting pipe 72 to move downward through the mounting tube 71. The connecting pipe 72 drives the second nozzle 73 to move downward, thereby extending the second nozzle 73 into the storage box 2. When the half gear 79 separates from the gear 78, the thrust generated by the extension of the spring 9 will drive the mounting tube 71 to move upward and reset through the horizontal plate 74. The mounting tube 71 drives the second nozzle 73 to move upward and reset through the connecting tube 72. The horizontal plate 74 will also drive the transmission plate 76 to rotate and reset through the fixed rod 77, thereby driving the second nozzle 73 to perform vertical reciprocating motion, further increasing the coverage area of ​​the second nozzle 73.

[0030] It is worth noting that the booster pump 12 disclosed in the above embodiments can be DGGD10, the motor 18 and the drive motor 21 can be ECMA-C20604RS, the electric push rod 19 can be YRJ0905, and the control switch group 3 is provided with control buttons corresponding to the booster pump 12, the motor 18, the drive motor 21 and the electric push rod 19 for controlling their switching.
