[0023] The effect achieved by the entire Example 1 is that by rotating the threaded rod 8, the push plate 9 can be pushed to move to the left under the action of the thread. At this time, the connecting rod 11 rotates, and drives the connecting plate 15, the connecting frame 13 and the protective plate 14 to rotate. The protective plate 14 can close the discharge port of the nozzle 6, thereby playing a protective role and avoiding the problem of blockage caused by impurities entering the discharge port. When spraying operations are required, by reversing the threaded rod 8, the push plate 9 moves to the right, and then the protective plate 14 opens the discharge port of the nozzle 6.

[0024] Example 2 is as follows Figure 1 - Figure 4 As shown, the mixing mechanism 3 includes two rotating shafts 301. The two rotating shafts 301 are rotatably connected inside the mixing tank 2. Stirring plates 302 are fixedly connected to the outer surfaces of the two rotating shafts 301. The tops of the two rotating shafts 301 movably penetrate through the mixing tank 2. Two gears 303 are fixedly sleeved on the outer surfaces of the two rotating shafts 301. The two gears 303 are meshed and connected. A mounting frame 304 is fixedly connected to the top of the mixing tank 2. A driving motor 305 is fixedly installed on the inner top of the mounting frame 304. The output end of the driving motor 305 is fixedly connected to one of the rotating shafts 301. The lifting mechanism 4 includes two support plates 401. The two support plates 401 are fixedly connected to the top of the base 1. Two electromagnetic guide rails 402 are installed on the opposite sides of the two support plates 401. Two electromagnetic sliders 403 are slidably connected to the two electromagnetic guide rails 402. A lifting plate 404 is fixedly connected to the opposite sides of the two electromagnetic sliders 403. A pump body 16 is fixedly installed on the top of the base 1. The input end of the pump body 16 is fixedly communicated with a suction hard pipe 17. One end of the suction hard pipe 17 away from the pump body 16 is communicated with the inside of the mixing tank 2. The output end of the pump body 16 is fixedly communicated with a hose 18. One end of the hose 18 away from the pump body 16 penetrates through the lifting plate 404 and is communicated with the inside of the spray gun 5. A self-locking universal wheel 19 is installed at the bottom of the base 1. A rotating cap 20 is fixedly installed at one end of the threaded rod 8.

[0025] The overall effect achieved by the entire Example 2 is that by setting the mixing mechanism 3, the driving motor 305 is started, so that the driving motor 305 drives one of the rotating shafts 301 to rotate. Since the two gears 303 are meshed and connected, the two rotating shafts 301 are driven to rotate. The two rotating shafts 301 drive the stirring plates 302 to rotate, which is convenient for fully stirring the spraying material in the mixing tank 2 to make it fully mixed. Then, by setting the lifting mechanism 4, by driving the electromagnetic guide rails 402, the electromagnetic sliders 403 reciprocate up and down on the electromagnetic guide rails 402, so that the spray gun 5 and the nozzle 6 are driven to reciprocate up and down synchronously, improving the spraying efficiency. Then, by starting the pump body 16, the pump body 16 extracts the spraying material in the mixing tank 2 through the suction hard pipe 17, transports it to the hose 18 and then sprays it through the nozzle 6, which is convenient for spraying operations. Then, by setting the self-locking universal wheel 19, it is convenient to move the spray gun 5 to a suitable working position. The rotating cap 20 is provided to facilitate the rotation of the threaded rod 8.

[0026] Working principle: When in use, the spray gun 5 is moved to a suitable working position through the self-locking universal wheels 19 provided. Then, the driving motor 305 is started, causing the driving motor 305 to drive one of the rotating shafts 301 to rotate. Since the two gears 303 are meshed and connected, the two rotating shafts 301 are driven to rotate. The two rotating shafts 301 drive the stirring plates 302 to rotate, fully stirring the spraying material in the mixing tank 2 to make it fully mixed. Subsequently, by starting the pump body 16, the pump body 16 extracts the spraying material in the mixing tank 2 through the suction hard pipe 17, transports it to the hose 18 and then sprays it out through the nozzle 6. At the same time, the electromagnetic guide rail 402 is driven, and the electromagnetic slider 403 reciprocates up and down on the electromagnetic guide rail 402, so as to drive the spray gun 5 and the nozzle 6 to reciprocate up and down synchronously, thus facilitating the spraying operation. When the spraying operation is completed, by rotating the rotary cap 20, the rotary cap 20 drives the threaded rod 8 to rotate, so that under the action of the thread, the push plate 9 can be pushed to move to the left. At this time, the connecting rod 11 rotates, and drives the connecting plate 15, the connecting frame 13 and the protective plate 14 to rotate. The protective plate 14 can close the discharge port of the nozzle 6, thus playing a protective role and avoiding the problem of blockage caused by impurities entering the discharge port. When spraying operation is required, by reversing the threaded rod 8, the push plate 9 is moved to the right, and then the protective plate 14 opens the discharge port of the nozzle 6.

[0027] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
