[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] Please refer to Figure 1-6 As shown, this utility model provides a spraying device for SOD liquid for plant foliar application, including a spray gun housing 1. An atomizing nozzle 2 is installed at one end of the spray gun housing 1. The atomizing nozzle 2 has a connecting end 3 at one end and is connected to a pump 5 installed inside the spray gun housing 1 via a connecting pipe 4. A connecting seat 6 is provided at the bottom of the spray gun housing 1. A storage bottle 7 for easy storage of SOD liquid is threadedly connected to the connecting seat 6. A suction pipe 8 is provided inside the storage bottle 7, one end of which is connected to the connecting pipe 4. A stirring mechanism to prevent the precipitation of SOD active ingredients is provided inside the storage bottle 7. An adjustment mechanism for easy adjustment of the spraying amount is provided inside the connecting end 3.
[0023] Specifically, during use, the pump 5 is started to draw SOD liquid from the storage bottle 7 through the suction pipe 8, and then transported to the atomizing nozzle 2 through the connecting pipe 4 for spraying. The stirring mechanism inside the storage bottle 7 can continuously stir to prevent the liquid from settling. At the same time, the spraying amount can be adjusted through the adjustment mechanism inside the connecting end 3, thereby achieving uniform and precise foliar spraying. Through the above structure, the effect of the liquid and the convenience of use are effectively improved.
[0024] The adjustment mechanism includes an adjustment rod 20. The bottom of the connecting end 3 has an extension end 16. A working chamber 17 is formed inside the extension end 16. Two sets of limiting rods 18 are slidably connected to the working chamber 17, and a sliding plate 19 is slidably connected to them. One side of the sliding plate 19 has an adjustment rod 20 slidably connected to the connecting end 3. One end of the adjustment rod 20 is tapered and matches the liquid inlet 21 on one side of the connecting end 3. The other side of the sliding plate 19 has a screw 22. A second micro motor 23 is installed at one end of the extension end 16. The output end of the second micro motor 23 extends to the inside of the working chamber 17 and is connected to a threaded cylinder 24 threadedly connected to the screw 22. The outer ring of the adjustment rod 20 is located at... The outer wall of the connecting end 3 is equipped with a sealing ring. By starting the second micro motor 23, it can drive the threaded cylinder 24 to rotate. The threaded cylinder 24 and the screw 22 are threaded together, which can drive the slide plate 19 to slide along the limiting rod 18, thereby driving the adjusting rod 20 to move back and forth. Since one end of the adjusting rod 20 is conical and adapted to the liquid inlet 21, the flow area of the liquid inlet 21 can be adjusted by changing the depth of the adjusting rod 20 into the liquid inlet 21. This allows for precise control of the SOD liquid spraying amount. The sealing ring can ensure the sealing of the connection to prevent liquid leakage. Thus, through this setting, the automated and precise adjustment of the SOD liquid spraying amount is realized, improving the ease of operation and measurement accuracy.
[0025] The stirring mechanism includes a stirring paddle 11. A first micro motor 9 is installed on the top of the connecting seat 6. The output end of the first micro motor 9 extends to the inner side of the connecting seat 6 and is connected to a rotating shaft 10. Three sets of stirring paddles 11 are installed on the outer ring of the rotating shaft 10 near one end. By starting the first micro motor 9, it can drive the rotating shaft 10 to rotate. The three sets of stirring paddles 11 on the outer ring of the rotating shaft 10 can rotate synchronously with the rotating shaft 10, thereby stirring the SOD liquid in the storage bottle 7. The stirring action of the stirring paddle 11 can prevent the precipitation of active ingredients in the liquid and ensure uniform concentration of the liquid. Thus, by setting it up, the foliar spraying effect and the utilization rate of active ingredients are effectively improved.
[0026] Among them, the outer ring of the rotating shaft 10 is fitted with a limiting disk 12 near the stirring paddle 11. The limiting disk 12 can prevent the suction pipe 8 from getting close to the stirring paddle 11.
[0027] The bottom of the spray gun housing 1 is provided with a handle 14, and a battery pack is installed inside the handle 14. The battery pack is connected to a circuit board 13 installed inside the spray gun housing 1. The circuit board 13 is connected to the pump 5, the first micro motor 9 and the second micro motor 23. A control button 15 connected to the circuit board 13 is provided on one side of the handle 14. When in use, the battery pack can provide power to the circuit board 13. When the control button 15 on the side of the handle 14 is pressed, the circuit board 13 receives the signal and controls the pump 5, the first micro motor 9 and the second micro motor 23 to work synchronously or separately, so as to realize the integrated electric operation of spraying, stirring and flow control.
[0028] Working principle: First, SOD liquid is injected into the storage bottle 7. The storage bottle 7 is then installed and fixed to the connecting seat 6 via threads. Pressing the control button 15 on the handle 14 activates the pump 5 via the circuit board 13. The pump 5 delivers the liquid to the atomizing nozzle 2 through the suction pipe 8 and connecting pipe 4. Simultaneously, the first micro motor 9 drives the rotating shaft 10 and stirring paddle 11 to rotate and stir the liquid to prevent sedimentation. The second micro motor 23 drives the threaded cylinder 24 to rotate, which in turn drives the slide plate 19 and conical adjusting rod 20 to move via the screw 22. The flow area of the inlet 21 is adjusted to control the amount of liquid sprayed. This allows for electric operation of spraying, stirring, and flow rate adjustment, ensuring uniform and precise spraying of the liquid and completing the entire operation process.
