[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 1 , Figure 2 , Figure 3The utility model provides an embodiment: an automatic spraying agricultural drone, comprising a body 1, a connecting plate 10 is fixedly connected to the bottom of the body 1, a guide groove 11 is provided inside the connecting plate 10, a motor 14 is fixedly connected to the inside of the connecting plate 10, a rotating shaft 15 is fixedly connected to the output end of the motor 14, a Z-shaped crank 16 is fixedly connected to the other end of the rotating shaft 15, a connecting rod 18 is fixedly connected to the outer side of the connecting plate 10, a swing rod 13 is rotatably connected to the other end of the connecting rod 18, a guide rod 12 is fixedly connected to the outer side of the swing rod 13, An adjustment hole 17 is provided inside the swing arm 13, a spray pipe 19 is fixedly connected to the bottom of the swing arm 13, a plurality of spray heads 20 are fixedly connected to the bottom of the spray pipe 19, a fixing plate 4 is detachably connected to the top of the body 1, a bolt 7 is connected to the internal thread of the fixing plate 4, a stirring assembly is provided on the top of the fixing plate 4, the other end of the guide rod 12 is slidably connected to the inner wall of the guide groove 11, the other end of the Z-shaped crank 16 is movably connected to the inner wall of the adjustment hole 17, wings 2 are fixedly connected to both sides of the outside of the body 1, and support frames 3 are fixedly connected to both sides of the outside of the body 1.

[0032] Specifically, the motor 2 14 drives the shaft 15 and the Z-shaped crank 16 to rotate in coordination, and the Z-shaped crank 16 moves in the adjustment hole 17, which increases the excellent flexibility of the swing rod 13 and the spraying tube 19, so that it can be precisely adjusted according to the needs of different crops and terrains. This adaptability not only ensures the accuracy of spraying, but also significantly improves the flexibility and efficiency of the UAV operation. Furthermore, by adjusting the speed and direction of the motor 2 14, the swing speed and amplitude of the swing rod 13 and the spraying tube 19 can be accurately controlled to achieve more delicate and accurate spraying operations. At the same time, combined with an advanced navigation system, the UAV can accurately identify and locate the target area to ensure that the liquid medicine is accurately sprayed to the desired location, thereby greatly reducing the waste of liquid medicine and improving the overall spraying efficiency. In addition, the uniformly mixed liquid medicine is prepared by an efficient stirring component to ensure the consistency and stability of the efficacy of each spraying, effectively improving the prevention and control effect of crops. Whether it is for large areas of farmland or complex terrain, this automatic spraying agricultural drone can show excellent performance. The support frames 3 on both sides of the body 1 provide a solid support foundation for the drone. Whether it is parked or in operation, the support frames 3 can ensure that the drone maintains a stable posture and effectively prevents tipping or damage caused by external forces. At the same time, the design of the wings 2 gives the drone excellent lift and stability, and can generate sufficient lift during flight, ensuring that the drone can maintain a stable flight state in various environments.

[0033] Reference Figure 1 , Figure 4 , Figure 5The stirring assembly includes a medicine tank 5, the bottom of the medicine tank 5 is fixedly connected to the top of the fixed plate 4, the top of the medicine tank 5 is fixedly connected to a motor 6, the output end of the motor 6 is fixedly connected to a connecting rod 25, the outer side of the connecting rod 25 is fixedly connected to a gear 22, the inner top wall of the medicine tank 5 is provided with an annular groove 29, the inner wall of the annular groove 29 is movably connected to an annular block 28, the bottom end of the annular block 28 is fixedly connected to a fixing rod 26, the outer side of the fixing rod 26 is fixedly connected to a gear 23, the inner wall of the medicine tank 5 is fixedly connected There is a gear ring 24, the outside of the fixed rod 26 and the outside of the connecting rod 25 are fixedly connected with multiple rotating plates 27, the outsides of the two gears 23 are meshed and connected with the inner side of the gear ring 24, the outside of the gear 23 is meshed and connected with the outside of the gear 1 22, and a fixed water pump 8 is fixedly connected to one side of the top of the fixed plate 4, the input end of the water pump 8 is fixedly connected to a connecting pipe 21, the medicine tank 5 is connected to the connecting pipe 21, and the output end of the water pump 8 is fixedly connected to a drug guide tube 9, and the other end of the drug guide tube 9 is fixedly connected to the inside of the spraying pipe 19.

[0034] Specifically, first, the motor 16 serves as the power source of the stirring system, and its output end is directly connected to the connecting rod 25. When the motor 16 is started, it drives the connecting rod 25 to rotate. The connecting rod 25 not only rotates itself, but also drives the gear 122 to rotate, and transmits the rotational power to the gear 2223 through the meshing connection between the gear 122 and the gear 223. The gear 223 is fixed on the fixed rod 26, and the fixed rod 26 and the connecting rod 25 rotate in the medicine tank 5. This design ensures that the liquid medicine can flow and stir in all directions in the medicine tank 5. At the same time, in order to increase the stirring effect, a plurality of rotating plates 27 are fixed on the outside of the fixed rod 26 and the connecting rod 25. Driven by the rotation of the fixed rod 26 and the connecting rod 25, the rotating plate 27 will rotate rapidly in the medicine tank 5 to form a strong stirring force. This stirring force can evenly mix the active ingredients in the liquid medicine and ensure the uniformity of the liquid medicine in the medicine tank 5. An annular block 28 is fixed to the top of the fixed rod 26, and the annular block 28 is movably connected to the annular groove 29 at the top of the medicine tank 5. As the gear 2 23 rotates, the annular block 28 will also rotate synchronously in the annular groove 29. This makes the stirring more stable. In addition, a gear ring 24 is fixed to the inner wall of the medicine tank 5. The outer sides of the two gears 23 are meshed and connected with the inner sides of the gear ring 24 to form a stable stirring system. The water pump 8 serves as a power source, and extracts the medicine liquid from the medicine tank 5 through the connecting pipe 21, and then transports it to the medicine spraying pipe 19 through the medicine guide pipe 9, and finally sprays it out from the nozzle 20. Secondly, the design of the nozzle 20 can ensure the uniform spraying of the medicine liquid. Multiple nozzles 20 are distributed at the bottom of the medicine spraying pipe 19, which can cover a wider area.

[0035] Working principle: The drone uses its built-in flight control system to fly autonomously according to the pre-set flight route. The wing 2 provides the necessary lift to ensure that the drone hovers or moves stably in the air. When it is necessary to spray the liquid medicine, the motor 6 is started at the same time to drive the connecting rod 25 and the gear 22 to rotate. Through the meshing of the gear 22 and the two gears 23, the gear 23 also rotates synchronously. The fixed rod 26 and the connecting rod 25 rotate in the medicine tank 5, driving the rotating plate 27 thereon to rotate rapidly, forming a strong stirring force. This stirring force ensures that the liquid medicine flows and mixes in all directions in the medicine tank 5 to avoid precipitation and stratification of the liquid medicine. When the liquid medicine is stirred evenly, the fixed water pump 8 starts to work. The water pump 8 extracts the liquid medicine from the medicine tank 5 through the connecting pipe 21, and then transports it to the spray pipe 19 through the medicine guide pipe 9. The spraying tube 19 is connected to the drone through the swing rod 13, and the motor 2 14 drives the rotating shaft 15 to rotate, and then drives the swing rod 13 to slide in the guide groove 11 through the Z-shaped crank 16 to adjust the angle of the spraying tube 19. Finally, the liquid medicine is evenly sprayed to the target area through multiple nozzles 20 at the bottom of the spraying tube 19.

[0036] 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.
