It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The present invention provides an automatic spraying device for agricultural plant protection. Figure 1-4As shown, the automatic spraying equipment for agricultural plant protection includes: a drone body 1 for mobile spraying for agricultural plant protection, on which a first assembly plate 2 and a second assembly plate 3 are fixedly mounted; a water tank 4 arranged on the first assembly plate 2, for holding agricultural plant protection liquid to be atomized and sprayed; a first atomizing nozzle 5 fixed to the bottom of the first assembly plate 2, for spraying agricultural plant protection liquid; side panels 6 respectively fixed to both sides of the drone body 1, on which adjustable second atomizing nozzles 7 are arranged; a pumping mechanism arranged on the second assembly plate 3, for pumping the liquid in the water tank 4 into the first atomizing nozzle 5 and the second atomizing nozzle 7; a driving mechanism arranged on the side panel 6, for driving and regulating the spraying position of the second atomizing nozzle 7.

[0022] In this embodiment, the drone body 1 serves as the mobile carrier for the entire device, providing flexible maneuverability for spraying operations and enabling free flight over crop planting areas. The first and second assembly plates 2 and 3 are fixedly mounted on the drone body 1, providing a stable mounting base for other components. Compared to traditional manual backpack spraying, the drone body 1 can easily cover large crop planting areas, eliminating the need for long hours of manual fieldwork and significantly improving operational efficiency. The setting of the assembly plate makes the overall structure of the equipment compact and stable, ensuring the smoothness of the spraying process; the water tank 4 is located on the first assembly plate 2, which is used to store agricultural plant protection solutions and provide a continuous source of solutions for spraying operations; during the operation, a sufficient amount of solutions can be loaded at one time, reducing the number of frequent additions of solutions and improving the continuous operation capability, which is especially suitable for large-area operation scenarios, avoiding the time wasted due to frequent replenishment of pesticides during manual spraying; the first atomizing nozzle 5 is fixed to the bottom of the first assembly plate 2, and the solutions in the water tank 4 are atomized and sprayed on the crops; the atomizing spraying method can make the solutions evenly cover the surface of the crops, thereby improving the utilization efficiency of the pesticides. Compared with the uneven spraying that may occur in manual spraying, it can more effectively control pests and diseases and ensure the healthy growth of crops; the side panels 6 are fixed on both sides of the drone body 1, and an adjustable second atomizing nozzle 7 is provided thereon. This design increases the coverage and flexibility of the spray; the second atomizing nozzle 7 with adjustable position can flexibly adjust the spray angle and direction according to factors such as the planting layout and height of the crops, achieving all-round and multi-angle spraying, further improving the spray effect, and ensuring that crops in different growth stages and planting patterns can be effectively sprayed; the pumping mechanism ensures the stable supply and reasonable distribution of the liquid medicine, and can ensure that the liquid medicine reaches the atomizing nozzle smoothly for spraying regardless of the flight posture of the drone. The design of the telescopic tube 11 can adapt to the vibration of the drone during flight and the relative displacement between the various components, ensuring the continuity and stability of the liquid medicine delivery and improving the reliability of the entire equipment; the driving mechanism realizes precise control of the spray direction; in summary, this automatic spraying equipment for agricultural plant protection effectively solves the problem of low efficiency of traditional manual spraying of pesticides, improves the efficiency and quality of agricultural plant protection operations, reduces the impact of pests and diseases on crop yield and quality, and brings significant benefits to agricultural production.

[0023] In a further preferred embodiment of the present invention, the pumping mechanism includes: a water pump 8 fixed on the second assembly plate 3, for pumping the medicine, a liquid extraction pipe 9 is provided on the liquid inlet end of the water pump 8, the liquid inlet end of the liquid extraction pipe 9 extends into the water tank 4, for pumping the medicine; a diversion pipe 10 fixedly connected to the liquid outlet end of the water pump 8, for diverting the medicine; a telescopic pipe 11 fixedly connected to the diversion pipe 10, and the corresponding liquid outlet ends of the telescopic pipe 11 are respectively fixedly connected to the first atomizing nozzle 5 and the second atomizing nozzle 7, for guiding the medicine.

[0024] In this embodiment, the water pump 8 is fixed to the second assembly plate 3 and is the power core of the entire pumping mechanism. Through its own working principle, it provides power for the transportation of the liquid medicine from the water tank 4 to the atomizing nozzle, thereby realizing the extraction of the liquid medicine. The setting of the water pump 8 enables the liquid medicine to overcome factors such as gravity and pipe resistance and be smoothly extracted from the water tank 4, providing the necessary premise for subsequent spraying operations. Compared with the manual backpack sprayer that relies on manual squeezing to spray, the water pump can continuously and stably provide pumping force, ensuring the continuity of the spray and greatly improving operation efficiency. One end of the liquid extraction pipe 9 is connected to the liquid inlet end of the water pump 8, and the other end extends into the water tank 4. It constructs a channel for the liquid medicine from the water tank 4 to the water pump 8, allowing the liquid medicine to be extracted by the water pump 8. This design of the liquid extraction pipe 9 ensures that the liquid medicine can accurately enter the water pump 8 from the water tank 4. Its reasonable layout in the water tank 4 can avoid the inhalation of air during the extraction process, ensure the stability of the extracted medicine, ensure the normal operation of the entire spray equipment, and reduce the spraying interruption caused by extraction problems; the diverter pipe 10 is fixedly connected to the liquid outlet end of the water pump 8, and it diverts the medicine extracted by the water pump 8. Since the equipment has a first atomizing nozzle 5 and a second atomizing nozzle 7 that need medicine supply, the diverter pipe 10 can reasonably distribute the medicine to different pipes according to the design, ensuring that each atomizing nozzle can obtain enough medicine, achieving comprehensive and uniform spraying, and improving the coverage and effect of pesticide spraying; one end of the telescopic tube 11 is fixedly connected to the diverter pipe 10, and the other end is fixedly connected to the first atomizing nozzle 5 and the second atomizing nozzle 7 respectively. It can adapt to the dynamic changes of adjustment while transporting medicine.

[0025] In a further preferred embodiment of the present invention, the driving mechanism includes: a steering shaft 12 rotatably mounted on the side panel 6; a motor 13 fixed to the top of the side panel 6, the output shaft of the motor 13 being fixedly connected to the steering shaft 12 via a coupling; a rotating plate 14 fixed to the bottom end of the steering shaft 12, a pipe rack being fixedly mounted on the bottom of the rotating plate 14 for fixing the second atomizing nozzle 7.

[0026] In this embodiment, the steering shaft 12 is rotatably mounted on the side plate 6. It is the key component connecting the motor 13 and the rotating plate 14. Driven by the motor 13, the rotating plate 14 rotates, thereby changing the direction of the second atomizing nozzle 7. This rotatable mounting arrangement allows the second atomizing nozzle 7 to flexibly adjust its angle, thus enabling the spray direction to be adjusted. Compared to fixed nozzles, this design better adapts to different crop planting layouts and terrain variations, ensuring that the spray reaches the desired area.

[0027] In a further preferred embodiment of the present invention, a groove plate 15 is symmetrically fixedly installed on the top of the first assembly plate 2, and a detachable connecting plate 16 is provided on the groove plate 15. The top of the connecting plate 16 is fixedly connected to the bottom of the water tank 4, and a bolt 17 is provided on the groove plate 15. The bolt 17 threadedly passes through the connecting plate 16 for limiting the position.

[0028] In this embodiment, the groove plate 15 is symmetrically fixedly mounted on top of the first assembly plate 2, providing a basic structure for mounting and limiting the connection plate 16. The connection plate 16 is arranged on the groove plate 15 and fixedly connected to the bottom of the water tank 4, serving to connect the water tank 4 and the first assembly plate 2. Bolts 17 are arranged on the groove plate 15 and threadedly penetrate the connection plate 16. The threaded connection secures the connection plate 16 within the groove plate 15, thereby stably limiting the water tank 4 to the first assembly plate 2. This combination of the groove plate 15, the connection plate 16, and the bolts 17 facilitates the installation and removal of the water tank 4. When the water tank 4 needs to be maintained, cleaned, or replaced, the bolts 17 can be easily unscrewed, separating the connection plate 16 from the groove plate 15, and removing the water tank 4. During installation, simply align the connection plate 16 with the groove plate 15 and secure it with the bolts 17. This is a simple and quick operation.

[0029] In a further preferred embodiment of the present invention, the water tank 4 is fixedly connected with a liquid infusion pipe, the liquid inlet end of the liquid infusion pipe is fixedly connected with a funnel, and the funnel is hinged with a cover plate.

[0030] In this embodiment, the provision of a refill tube solves the problem of insufficient solution in water tank 4 during spraying operations. When the amount of solution in water tank 4 decreases, it can be promptly replenished through the refill tube. The presence of the funnel makes refilling more convenient and accurate. Its large opening allows for various tools (such as a ladle or measuring cup) to pour the solution. Compared to adding the solution directly into the narrower refill tube, this reduces the possibility of spillage and improves the convenience of refilling. The cover plate covers the funnel when not in use, preventing dust and debris from entering the refill tube and water tank 4, thereby preventing contamination of the solution.

[0031] In a further preferred embodiment of the present invention, a tube hole is opened on the side plate 6, the inner diameter of the tube hole is larger than the telescopic tube 11, and the first atomizing nozzle 5 and the second atomizing nozzle 7 are both fixedly connected to atomizing nozzles.

[0032] In this embodiment, the inner diameter of the tube hole is larger than that of the telescopic tube 11 . This design provides sufficient space for the telescopic tube 11 to move within the side plate 6 .

[0033] In a further preferred embodiment of the present invention, a reinforcing rib is fixedly mounted on both the first assembly plate 2 and the second assembly plate 3 , and one end of the reinforcing rib is fixedly connected to the frame of the drone body 1 .

[0034] In this embodiment, the first assembly plate 2 and the second assembly plate 3 serve as important structures for supporting other components, and reinforcing ribs are fixedly installed thereon; one end of the reinforcing rib is fixedly connected to the frame of the drone body 1, tightly connecting the assembly plate and the drone body 1, thereby enhancing the stability of the overall structure.

[0035] In summary, the coordination of the drone body 1 with the first and second assembly plates 2 and 3 provides the device with flexible maneuverability and a stable mounting base, significantly improving operational efficiency and ensuring a smooth spraying process. This allows for easy coverage of large crop planting areas, eliminating the need for lengthy manual field work. The water tank 4 stores the pesticide, reducing the need for frequent dosing and improving continuous operation, avoiding time wasted manually replenishing pesticides during spraying and ensuring a continuous supply of pesticides for spraying. The first atomizing nozzle 5 and the adjustable second atomizing nozzle 7 achieve uniform, all-round, and multi-angle spraying. The first atomizing nozzle 5 atomizes the pesticide and sprays it, evenly covering the crop surface and improving pesticide utilization efficiency. The second atomizing nozzle 7 can flexibly adjust its angle and direction based on factors such as the crop planting layout and height. Compared to the unevenness of manual spraying and the limitations of fixed nozzles, this sprayer can more effectively control pests and diseases, adapt to crops at different growth stages and planting patterns, and improve spray effectiveness.
