[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 2 The utility model provides an embodiment: a pesticide spraying drone, including a stirring tank 1, a motor 2 is fixedly connected to the middle side of the top of the stirring tank 1, a stirring rod 4 is fixedly connected to the output end of the motor 2, a plurality of sliding rods 5 are slidably connected to the inner side of the stirring rod 4, a spring 6 is sleeved on the outer side of the sliding rod 5, a baffle 8 is fixedly connected to one end of the sliding rod 5, a scraper rod 7 is fixedly connected to the other end of the sliding rod 5, and a spraying mechanism is arranged at the bottom end of the stirring rod 4.

[0032] Specifically, the starter motor 2 is first activated, and the motor 2 drives the stirring rod 4 to rotate. This rotation further promotes the linkage movement of the slide bar 5, and the rotation of the slide bar 5 drives the rotation of the scraper rod 7. In this process, the pesticide is fully mixed with the inner wall of the stirring tank 1. The function of the scraper rod 7 is to effectively scrape off the materials adhering to the tank wall while mixing, so as to achieve a cleaning effect. However, when the performance of the scraper rod 7 decreases due to wear, the built-in spring 6 will intervene and play a role. It compresses the scraper rod 7 so that it fits tightly against the inner wall of the stirring tank 1, ensuring that the cleaning process can be maintained or improved even when the scraper rod 7 is worn.

[0033] Reference Figure 2 - Figure 4 The spraying mechanism includes a turntable 9 and two fixed blocks 13. The middle side of the top of the turntable 9 is fixedly connected to the bottom end of the stirring rod 4. The fixed block 13 is fixedly connected to the outer side of the lower part of the motor 2 at one end close to the stirring rod 4. A thin rod 10 is fixedly connected to the bottom of the turntable 9. A hollow shell 11 is slidably connected to the outer side of the thin rod 10. Two connecting rods 12 are fixedly connected to the outer side of the hollow shell 11. A joint 14 is fixedly connected to the end of the connecting rod 12 away from the hollow shell 11. A plurality of spray heads 15 are fixedly connected to the bottom of the joint 14. The outer side of the connecting rod 12 is slidably connected to the inside of the fixed block 13. A delivery pipe 16 is fixedly connected to the middle part of the outer side of the joint 14. A feed pump 17 is arranged on the outer side of the delivery pipe 16.

[0034] Specifically, after the stirring is completed, the system starts the feed pump 17, and the pesticide flows smoothly into the delivery pipe 16. Through the precision joint 14, the pesticide is accurately delivered to the spray head 15, and finally sprayed out in a uniform atomized form. At the same time, the continuous rotation of the stirring rod 4 is not limited to itself, it also drives the turntable 9 at the bottom, causing the turntable 9 to rotate accordingly. This rotational action is further transmitted to the thin rod 10, causing the thin rod 10 to slide left and right inside the hollow shell 11. This sliding mechanism causes the hollow shell 11 to produce continuous movement in the front and rear directions, and this movement further drives the connecting rod 12. The flexible movement of the connecting rod 12 in the fixed block 13 causes the joint 14 and the spray head 15 to swing back and forth in coordination.

[0035] Reference Figure 2 - Figure 4 One end of the spring 6 is fixedly connected to the outside of the stirring rod 4, and the other end of the spring 6 is fixedly connected to the outside of the scraper rod 7. The scraper rod 7 conflicts with the inner wall of the stirring tank 1. The stirring rod 4 is rotatably connected to the inside of the stirring tank 1 on both the upper and lower sides. Two fixed seats 18 are fixedly connected to the outside of the stirring tank 1, and a fixed shaft frame 19 is fixedly connected to the outside of the fixed seat 18. A propeller 20 is arranged on the outside of the fixed shaft frame 19. A feed port 3 is fixedly connected to the right side of the top of the stirring tank 1, and a control system 21 is fixedly connected to the right side of the stirring tank 1. One end of the conveying pipe 16 is fixedly connected to the lower part of the outer side of the stirring tank 1.

[0036] Specifically, one end of the spring 6 is firmly connected to the outside of the stirring rod 4, and the other end is fixed to the outside of the scraper rod 7. The scraper rod 7 is in close contact with the inner wall of the mixing tank 1, which plays the role of scraping off adhesions and keeping the tank wall clean. The stirring rod 4 moves up and down inside the mixing tank 1 to ensure that the materials can be fully and evenly mixed. Two fixed seats 18 are provided on the outside of the mixing tank 1, which are fixedly installed with a fixed shaft frame 19. The fixed shaft frame 19 is equipped with a propeller 20 on the outside, which allows the drone to provide stable power during flight and also assists the movement of the mixing tank 1. A feed port 3 is set on the right side of the top of the mixing tank 1 to facilitate the addition of pesticides or other substances. A control system 21 is fixedly connected on the right side for monitoring and adjusting the working state of the drone, including stirring speed, spraying mode, etc., to ensure the accuracy and efficiency of the operation. One end of the conveying pipe 16 is fixed at the bottom of the outer side of the mixing tank 1, which transports the mixed pesticide to the area to be treated.

[0037] Working principle: start the motor 2, drive the stirring rod 4 to rotate, and then drive the sliding rod 5 to rotate, thereby driving the scraper rod 7 to rotate. During the full stirring process, some materials will adhere to the inner wall of the stirring tank 1, and the scraper rod 7 will scrape the materials away from the inner wall as it rotates, thereby achieving a cleaning effect. When the scraper rod 7 is worn, the spring 6 will compress the scraper rod 7 so that the scraper rod 7 is tightly attached to the inner wall of the stirring tank 1. After sufficient stirring, drive the feed pump 17, and the pesticide enters the delivery pipe 16, and is finally sprayed out through the spray head 15 through the joint 14. At the same time, the rotation of the stirring rod 4 will also drive the turntable 9 at the bottom to rotate, thereby driving the thin rod 10 to rotate, and then the thin rod 10 slides left and right in the hollow shell 11, which will drive the hollow shell 11 to move back and forth repeatedly, and then drive the connecting rod 12 to move back and forth repeatedly inside the fixed block 13, and then drive the joint 14 and the spray head 15 to move back and forth repeatedly, so that the spraying range is expanded and the utilization rate of the liquid medicine is improved.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
