[0030] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0031] like Figures 1 to 4 As shown, a precision pesticide spraying device comprises a spraying device body 1, a mounting plate 2 is arranged on one side of the spraying device body 1, a handheld spraying rod 3 is movably connected to the mounting plate 2, the handheld spraying rod 3 and the spraying device body 1 are connected through a pipeline, the handheld spraying rod 3 is hollow inside, a water outlet pipe is arranged on one side of the spraying device body 1, the pesticide inside the spraying device body 1 is pumped from the water outlet pipe into the space inside the handheld spraying rod 3 by a water pump arranged inside the spraying device body 1, a plurality of water outlet holes 4 are evenly arranged at the bottom end of the handheld spraying rod 3, a spray nozzle 5 is fixedly connected to the water outlet hole 4, the pesticide entering the handheld spraying rod 3 enters the spray nozzle 5 from the water outlet hole 4, and finally is sprayed out through the spray nozzle 5 to spray the crops;

[0032] like Figures 1 to 5As shown, a plurality of limiting slots 6 are provided on the upper end surface of the hand-held spray rod 3, and a limiting block 7 for pressing the water outlet hole 4 is slidably connected inside the limiting slot 6. An elastic pressing member is arranged between the hand-held spray rod 3 and the limiting block 7. In this embodiment, the elastic pressing member is made of a spring, and the spring is installed between the hand-held spray rod 3 and the limiting block 7. The spring pushes the limiting block 7 toward the water outlet hole 4. In the initial state, under the action of the spring, the limiting block 7 presses against the water outlet hole 4, so that the pesticide inside the hand-held spray rod 3 cannot pass through the water outlet hole 4. A rotating plate 8 is rotatably connected to the mounting plate 2, and the rotating plate 8 can swing up and down on the mounting plate 2. One end of the hand-held spray rod 3 is rotatably connected to the rotating plate 8, and a rotating shaft is fixedly connected to the rotating plate 8. One end of the hand-held spray rod 3 is rotatably connected to the rotating plate 8. When in use, when the hand-held spray rod 3 is swung upward, the rotating plate 8 is synchronously driven to swing upward.

[0033] like Figures 2 to 4 As shown, a pushing structure for pushing the limit block 7 to slide is provided on the handheld spray rod 3. The pushing structure can adopt an electric pushing rod to control the limit block 7 to slide in the direction away from the water outlet 4. When in use, the electric pushing rod is controlled to start by controlling the switch, thereby controlling the limit block 7 to slide.

[0034] like Figures 1 to 5 and Fig. 9 As shown, another driving structure is provided in the present embodiment. Specifically, the driving structure includes a plurality of looped air passages 9 opened on both sides of the handheld spray rod 3. The looped air passages 9 are distributed on both sides of the spray nozzle 5. A pressure air chamber 10 is opened above the looped air passage 9. Both sides of the pressure air chamber 10 are connected to the looped air passage 9. A pressure top block 11 is slidably connected inside the pressure air chamber 10. The pressure top block 11 is slidably connected inside the pressure air chamber 10. The upper end of the pressure top block 11 is fixedly connected to the limit block 7. When the pressure top block 11 slides up and down, the limit block 7 is synchronously driven to slide up and down. An air release hole 12 is opened on the pressure top block 11. A pneumatic push rod 13 is slidably connected inside the looped air passage 9. Both ends of the pneumatic push rod 13 are fixedly installed with closed push blocks 23. The cross section of the closed push block 23 is set to be an isosceles trapezoid. The closed push block 23 is made of rubber material.

[0035] like Figures 5 to 8As shown, both ends of the loop-shaped airway 9 near the pressure air chamber 10 are provided with a one-way flow structure, the one-way flow structure includes a flow limiting baffle 16 and a ventilation baffle 17 fixedly installed inside the loop-shaped airway 9, a control ball 18 is arranged between the flow limiting baffle 16 and the ventilation baffle 17, a conical one-way air outlet 19 is opened on the flow limiting baffle 16, a through hole 20 is opened on the ventilation baffle 17, and a support baffle 21 is fixedly connected to one end of the ventilation baffle 17 near the flow limiting baffle 16; when the gas enters the loop-shaped airway from the through hole 20, the gas will enter the loop-shaped airway 9. When the gas enters the one-way gas outlet 19 and goes out from the through hole 20, the gas pushes the control ball 18 toward the through hole 20 until the control ball 18 contacts the supporting baffle 21, so that the control ball 18 cannot block the through hole 20. At this time, the gas can pass through the one-way gas outlet 19 and the through hole 20 and finally enter the pressure gas chamber 10.

[0036] like Figures 1 to 9 As shown, when in use, the air pressure push rod 13 is pushed in the direction away from the spray device body 1 so that the air pressure push rod 13 slides inside the looped air passage 9, and the closed push block 23 at one end away from the spray device body 1 pushes the gas inside the looped air passage 9 to enter from the one-way air outlet 19 and go out from the through hole 20. The gas pushes the control ball 18 in the direction close to the through hole 20 until the control ball 18 contacts the support baffle 21, so that the control ball 18 cannot block the through hole 20. At this time, the gas can finally enter from one side of the pressure chamber 10 through the one-way air outlet 19 and the through hole 20; the air inside the pressure chamber 10 increases, and the air in the pressure chamber 10 enters the through hole 20 from the other side. When the gas enters the looped air passage 9 from the through hole 20, the gas pushes the control ball 18 to the direction close to the one-way air outlet 1 9 is pushed until the control ball 18 blocks the one-way air outlet 19. At this time, the gas cannot go out through the one-way air outlet 19, the air inside the pressure air chamber 10 increases, and the pressure top block 11 is pushed out in the direction away from the pressure air chamber 10, so that the limit block 7 is pushed in the direction away from the water outlet 4. At the same time, the air slowly flows out from the air leakage hole 12. When the air pressure push rod 13 stops sliding, the pressure inside the pressure air chamber 10 is restored, and the spring pushes the limit block 7 in the direction close to the water outlet 4 again until the limit block 7 blocks the water outlet 4; when the air pressure push rod 13 is pushed in the direction away from the spray device body 1, the closed push block 23 close to one end of the spray device body 1 is pushed in the direction away from the spray device body 1. At this time, the air enters the inner part of the circular air passage 9 through the inclined surface of the closed push block 23.

[0037] like Figure 1 to Figure 2 and Figures 5 and 6 and Fig. 9As shown, the pneumatic push rod 13 is driven by a driving structure, which includes a sliding frame 14 slidably connected to the hand-held spray rod 3, and push rods 15 are fixedly connected on both sides of the sliding frame 14. The push rod 15 is fixedly connected to the pneumatic push rod 15, and one end of the drive rod 25 is rotatably connected to the rotating plate 8, and the other end of the drive rod 25 is slidably connected to the sliding frame 14.

[0038] like Figures 2 to 4 As shown, when in use, the handheld spraying rod 3 is swung laterally, and the driving rod 25 pushes the sliding frame 14 to slide on the handheld spraying rod 3, so that the gas pressure push rod 15 pushes the gas pressure push rod 13 to slide.

[0039] like Figures 1 to 4 As shown, one end of the limiting block 7 close to the water outlet 4 is fixedly connected with a sealing ring sleeve 22 , and the sealing ring sleeve 22 is used to seal the water outlet 4 to prevent the pesticide from leaking out of the water outlet 4 .

[0040] like Figures 2 to 4 As shown, a pulling handle 24 is fixedly connected to the handheld spraying rod 3, and the handheld spraying rod 3 is conveniently controlled by pulling the handle 24.

[0041] like Figures 1 to 9 As shown, during the specific implementation:

[0042] The pesticide inside the spray device body 1 is pumped from the water outlet pipe into the space inside the handheld spray rod 3 by a water pump arranged inside the spray device body 1 .

[0043] The hand-held spraying rod 3 is swung horizontally, and at this time, the driving rod 25 pushes the sliding frame 14 to slide on the hand-held spraying rod 3, so that the air pressure push rod 15 pushes the air pressure push rod 13 to slide;

[0044] When the air pressure push rod 13 is pushed in a direction away from the spray device body 1, the air pressure push rod 13 slides inside the looped air passage 9, and the closed push block 23 at one end away from the spray device body 1 pushes the gas inside the looped air passage 9 to enter from the one-way air outlet 19 and go out from the through hole 20. The gas pushes the control ball 18 in a direction close to the through hole 20 until the control ball 18 contacts the support baffle 21, so that the control ball 18 cannot block the through hole 20. At this time, the gas can finally enter from one side of the pressure air chamber 10 through the one-way air outlet 19 and the through hole 20;

[0045] The air inside the pressure chamber 10 increases, and the air in the pressure chamber 10 enters the through hole 20 from the other side. When the gas enters the inside of the circular airway 9 from the through hole 20, the gas pushes the control ball 18 toward the one-way air outlet 19 until the control ball 18 blocks the one-way air outlet 19. At this time, the gas cannot go out through the one-way air outlet 19.

[0046] As the air inside the pressure chamber 10 increases, the pressure top block 11 is pushed out in the direction away from the pressure chamber 10, so that the limit block 7 is pushed in the direction away from the water outlet 4, and the pesticide entering the handheld spray rod 3 enters the spray nozzle 5 from the water outlet 4, and is finally sprayed out through the spray nozzle 5 to spray the crops; at the same time, the air slowly flows out from the air leak hole 12, and when the air pressure push rod 13 stops sliding, the pressure inside the pressure chamber 10 decreases, and the spring pushes the limit block 7 in the direction close to the water outlet 4 again until the limit block 7 blocks the water outlet 4.

[0047] When the air pressure push rod 13 is pushed away from the spray device body 1, the sealed push block 23 close to one end of the spray device body 1 is pushed away from the spray device body 1. At this time, air enters the inner part of the circular air passage 9 through the inclined surface of the sealed push block 23.

[0048] When the air pressure push rod 13 is pushed toward the spray device body 1, the principle is the same as above.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
