[0001] The present invention relates to the technical field of special nozzles for unmanned aerial vehicles (UAVs), and in particular to a special nozzle for unmanned aerial vehicles (UAVs) for spraying biocontrol agents. Background Art

[0002] With the development of artificial intelligence (AI) and its application in precision spraying equipment, precision pesticide application has become a crucial technology for improving pesticide application efficiency. Drones (UAVs) are widely used in various fields, including agricultural pest control. However, existing drone spray equipment typically consists of a spray gun, fan nozzle, or a spray system.

[0003] In production practice, low spraying efficiency, liquid pesticide waste, and difficulty adjusting the spray range are common problems. Currently, chemical control is the primary method for controlling crop diseases. While this method is effective, it often prioritizes treatment over prevention in crop management, and lacks the support of accurate prediction technology. This results in high chemical dosages and the inability to adjust the nozzle size based on the drone's height above the farmland. This not only results in low pesticide utilization, but also causes certain environmental pollution and poses a risk to human health and safety. Therefore, to address these issues, a drone-specific nozzle was designed for spraying biocontrol agents to overcome the shortcomings of existing technologies. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] See Figure 1-4 , including, a nozzle shell 1, a nozzle base 5 is provided at the bottom of the nozzle shell 1; between the nozzle shell 1 and the nozzle base 5 are provided: a liquid spray shell 18, the liquid spray shell 18 is provided on the top of the nozzle base 5; an infusion tube 3 is provided inside the liquid spray shell 18; the nozzle outer clip 11 of the nozzle shell is symmetrically provided; the nozzle inner clip 12 is symmetrically provided inside the nozzle outer clip 11; the liquid outlet 2 is provided in the middle of the nozzle inner clip 12 and docked with the top of the infusion tube 3; the throttle valve 10 is provided inside the nozzle base 5, and the output port is docked with the liquid outlet 2; the pressure valve 9 is provided inside the throttle valve 10; replaceable A plug 8 is located at the bottom of the nozzle base 5 and connects to the drone's pesticide delivery pipe. The liquid outlet 2 is a slit-shaped device, enabling precise spraying, controlled speed, and spraying range, minimizing pesticide waste and reducing environmental impact. The liquid infusion tube 3 is internally provided with a liquid pipe wall 13, comprising a stirring shaft 14 disposed within the liquid pipe wall 13; a bottom bearing 17 rotatably mounted on the bottom inner wall of the liquid pipe wall 13 and connected to the stirring shaft 14 at its top; multiple couplings 15, all mounted on the outer side wall of the bottom bearing 17; and multiple sets of stirrers 16, all symmetrically mounted on the outer side wall of the coupling 15. A threaded temperature sensor 4 is mounted on the outer side wall of the spray housing 18 and can be remotely controlled by the drone. The adjustable nozzle allows the spray range and angle to be adjusted based on the type and height of the crop, and the type and density of the pests and diseases, ensuring uniform application. The inner wall of the nozzle housing 1 and the bottom of the nozzle base 5 are both provided with sealing gaskets 6. The outer wall of the liquid spray housing 18 is equipped with a threaded temperature sensor 4, which can detect the ambient temperature in real time and feed back the data to the drone control system. A filter screen 7 is provided on the top of the replaceable plug 8 to block the flow of impurities. The infusion tube 3 is located at the center of the nozzle housing 1, with one end connected to the liquid outlet 2 and the other end connected to the nozzle base 5. The coupling 15 and the agitator 16 are arranged on the outer wall of the bottom bearing 17 and have the same spacing. The outer surface of the agitator 16 is provided with a plurality of holes for the flow of liquid.

[0028] During use, the specialized nozzle features a variety of interchangeable plugs 8, making it compatible with various drone models, including multi-rotor and fixed-wing models. Installing the nozzle on a drone ensures a secure connection. When applying antimicrobial agents, a threaded temperature sensor 4 monitors environmental changes in real time and feeds this data back to the drone's control system. Through close integration with the control system, the drone can adjust spraying position and angle in real time based on spraying requirements. Pressure valve 9 and throttle valve 10 regulate the flow of the liquid, ensuring accurate and efficient application. The nozzle housing 1 is located on the front surface, protecting the internal infusion tube 3, threaded temperature sensor 4, and other components. The biocontrol agent flows through the infusion tube 3, passes through a filter 7 to initially filter out impurities, and then enters the nozzle base 5. The nozzle base is equipped with a pressure valve 9 and throttle valve 10. A sealing gasket 6 prevents leakage of the agent. Simultaneously, the pressure valve 9 sprays the agent from the liquid outlet 2. The pressure valve 9 can be opened or closed to adjust the pressure of the biocontrol agent according to the requirements of the drone system. This helps maintain a safe and stable operating range for the system. The throttle valve 10 controls the flow rate of the fluid in the pipeline, thereby achieving flow regulation. It limits the speed at which the biocontrol agent flows through the pipeline, allowing the drone to control the desired flow rate, achieving both speed control and spray coverage. The liquid outlet 2 is equipped with an inner nozzle clip 12 and an outer nozzle clip 11, ensuring that other components mounted on the shaft or within the inner bore maintain a stable position.

[0029] The infusion tube 3 is internally provided with a liquid tube wall 13. Also located within this wall are a stirring shaft 14, a coupling 15, and an agitator 16. The upper end is connected to the liquid outlet 2, and the lower end is connected to the nozzle base 5 via a bottom bearing 17. After the nozzle is inserted into the drone, the inoculum enters the infusion tube 3 through the nozzle base 5. The stirring shaft 14 drives the agitator 16, which, after uniform distribution, is sprayed out of the liquid outlet 2 by the pressure valve 9. This ensures more uniform dispensing of the liquid. Furthermore, the equal spacing between the coupling 15 and the agitator 16, and the presence of holes in the agitator, ensures more thorough mixing of the liquid during stirring.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific embodiments described. Obviously, many modifications and variations are possible based on the content of this specification.
