[0034] like Figure 1 , Figure 3 and Figure 5 , pour the liquid medicine or solid pesticide required for pest control from the liquid inlet 5 into the mixing box 4. When the liquid medicine or water hits the turbine 11 from above, it will drive the turbine 11 to rotate. The rotation of the turbine 11 drives the stirring rod 12 below to rotate. The stirring rod 12 stirs and mixes the liquid medicine in the mixing box 4, and starts the plunger pump 6. The plunger pump 6 extracts the mixed liquid medicine in the mixing box 4. The liquid medicine is filtered by the filter screen 17. The plunger pump 6 produces a pressurized effect on the liquid medicine entering the pipeline 10. The pressurized liquid medicine moves from the pipeline 10 to the high-pressure nozzle 9, and is atomized and sprayed by the high-pressure nozzle 9 to produce a spray from both sides of the device to control pests and diseases on plants. At this time, the handle 3 is held to push the device. Under the action of the universal wheel 2 on the lower surface of the base 1, the device can be easily moved to control plants, thereby reducing the labor intensity of the staff. Example 2

[0035] On the basis of Example 1, this device has the effect of preventing precipitation, specifically:

[0036] The rotating shaft 13 is rotatably mounted on the lower surface of the mixing box 4, and the rotating shaft 13 passes through the lower surface of the mixing box 4. The outer surface of the rotating shaft 13 is provided with a stirring rod 12. The other end of the rotating shaft 13 is connected to a bevel gear 14.

[0037] like Figure 1 , Figure 3 and Figure 6When the device is in motion, the rotating wheel 16 rotates as the device moves forward. When the rotating wheel 16 rotates, the rotating wheel 16 drives the bevel gear 2 15 to rotate, the rotation of the bevel gear 2 15 drives the bevel gear 1 14 to rotate, the rotation of the bevel gear 14 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the stirring rod 12 on the outer surface to stir the liquid in the mixing box 4, so that during the movement of the device, the stirring rod 12 at the rotating shaft 13 always keeps in a moving state to prevent precipitation. Example 3

[0038] On the basis of Example 2, this device has the effect of adjusting the height, specifically:

[0039] The rack 18 is connected to the surface of the connecting plate 8, and the rack 18 is slidably installed inside the support plate 7. A driven wheel 19 is rotatably installed inside the support plate 7. A tooth block is arranged on the outer surface of the driven wheel 19 to mesh with the rack 18. A knob 20 is rotatably arranged on the outer surface of the handle 3, and a connecting rod is arranged inside the knob 20 to penetrate the surface of the support plate 7 and connect to the driven wheel 19.

Figure 2 Taking the left high-pressure nozzle 9 as an example, turn the buckle on the surface of the handle 3 to loosen the knob 20, turn the knob 20 on the surface of the handle 3, and the rotation of the knob 20 drives the driven wheel 19 to rotate. When the driven wheel 19 rotates clockwise, the driven wheel 19 drives the rack 18 to move downward, and the rack 18 drives the connecting plate 8 to slide downward, so that the height of the high-pressure nozzle 9 decreases. When the driven wheel 19 rotates counterclockwise, it drives the rack 18 to move upward, thereby increasing the height of the high-pressure nozzle 9. After the height adjustment is completed, turn the buckle in the opposite direction to fix the knob 20. Similarly, the high-pressure nozzle 9 on the other side can be driven by the knob 20 to adjust the spraying height.

[0041] Working principle: When using the spray device for controlling plant diseases and insect pests, pour the medicine liquid into the mixing box 4 from the liquid inlet 5, the medicine liquid drives the turbine 11 to rotate, the turbine 11 drives the stirring rod 12 to mix the medicine liquid, start the plunger pump 6, the medicine liquid passes through the pipeline 10 driven by the plunger pump 6, and is sprayed from the high-pressure nozzle 9 to control the plants, the handheld handle 3 drives the device to move, when the device moves, the rotating wheel 16 rotates, driving the bevel gear 15 to rotate, thereby driving the rotating shaft 13 and the stirring rod 12 thereto to rotate, to prevent the medicine liquid from settling, turn the knob 20 on the surface of the handle 3, the knob 20 drives the driven wheel 19 to rotate, thereby driving the rack 18 to move up and down, to adjust the height of the high-pressure nozzle 9, and to increase the overall practicality.
