Technical Field
[0001] This utility model relates to the field of drone technology, and in particular to a flower pollination drone. Background Technology
[0002] Pollination is a crucial part of the life cycle of flowering plants, and it can be done in various ways, including self-pollination and pollination by external forces such as wind and insects. Among these, pollination by insects such as bees is essential for about three-quarters of the world's crops. However, the use of pesticides and climate change have led to a sharp decline in the number of pollinating insects, resulting in an increasing demand for artificial pollination. Traditional manual pollination is labor-intensive, while existing machine pollination methods also have drawbacks such as rising pollen costs. Against this backdrop, flower pollination drones have emerged as a new technological solution for achieving autonomous and precise pollination of crops.
[0003] Flower pollination drones typically have a lightweight and sturdy fuselage, equipped with multi-rotor or fixed-wing flight components to ensure stable flight in agricultural environments. The fuselage is equipped with a container for storing pollen, and a blower-like airflow device blows the pollen out of the container during flight. With the help of satellite positioning and visual recognition, the drone can shuttle over the farmland according to a preset path. The downdraft generated by its flight carries the pollen away, or it uses electrostatic adsorption and other technologies to make the pollen fall precisely on the target flowers, achieving efficient pollination.
[0004] With the large-scale development of modern agriculture, traditional flower pollination drones often suffer from pollen waste or insufficient pollination when facing flower areas with different planting densities due to the lack of mechanical structure for precisely adjusting the amount of pollen sprayed. Therefore, a flower pollination drone is proposed to solve the above problems. Utility Model Content

[0031] 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.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a flower pollination drone, comprising a shell 1, which serves as the main frame of the drone, providing space for the installation and protection of various internal components. It effectively resists the influence of the external environment on the drone's internal structure, ensuring the drone's normal operation. A base plate 2 is fixedly connected to the bottom of the shell 1, playing a crucial supporting and load-bearing role. The base plate 2 provides a stable platform for the components mounted on it, ensuring the relative stability of the various components during flight and operation. A pollen storage box 4 is fixedly connected to the top of the base plate 2. The pollen storage box 4 is a key component for storing pollen, and its internal space can accommodate… The abundant pollen provides a sufficient pollen source for the pollination operation of the drone, ensuring the continuity of the pollination work. The front end of the pollen storage box 4 is fixedly connected to the input pipe 5, which is the channel connecting the pollen storage box 4 and the subsequent pollen transmission component. The front end of the input pipe 5 is fixedly connected to the fixing block 12, the top of the fixing block 12 is fixedly connected to the motor 8, the front end of the fixing block 12 is fixedly connected to the fixing box 6, the inside of the fixing box 6 is rotatably connected to the rotating disk 7, and the front end of the fixing box 6 is fixedly connected to the output pipe 10. The fixing box 6 provides a space for the rotating disk 7 to rotate and a protective cover, so that the rotating disk 7 can operate stably during the process of adjusting the pollen flow rate, while preventing pollen from leaking to the outside.
[0033] The rotating disk 7 has multiple flow channels 9. By rotating the rotating disk 7, the flow rate between the input pipe 5 and the output pipe 10 can be changed, thereby adjusting the pollen flow rate. This design can flexibly adjust the amount of pollen sprayed according to the density of flowers in different scenarios, avoiding pollen waste and improving pollen utilization. The front end of the output pipe 10 is fixedly connected to the spray pump 11. The output pipe 10 is the channel for transporting the pollen after the flow rate adjustment to the spray pump 11. The output pipe 10 ensures that the pollen can be accurately transferred from the fixed box 6 to the spray pump 11, preparing for subsequent spraying and pollination. The spray pump 11 is the key component for pollen spraying. The spray pump 11 extracts the pollen inside the pollen storage box 4 and sprays it out through the spray head 20 at an appropriate pressure and flow rate to pollinate the flowers, ensuring that the pollen can be evenly covered on the flowers and improving the success rate of pollination. The front end of the spray pump 11 is equipped with a docking sealing component, which enables quick connection and sealing between the spray head 20 and the spray pump 11, facilitating cleaning and replacement of the spray head 20, while ensuring that pollen does not leak during pollination operations. The fixed box 6 is externally fixedly connected to the front end of the fixed block 12. This connection method ensures the stability of the fixed box 6 on the fixed block 12, allowing the rotating disk 7 to work normally when adjusting the pollen flow rate. The drive end of the motor 8 is fixedly connected to the rear end of the rotating disk 7. Through this connection method, the motor 8 can effectively drive the rotating disk 7 to rotate inside the fixed box 6, thereby controlling the pollen flow rate.
[0034] The fixing block 12 is externally fixedly connected to the top of the base plate 2, ensuring the stability of the fixing block 12 and the components such as the motor 8 and the fixing box 6 installed on it during the operation of the drone. The spray pump 11 is externally fixedly connected to the top of the base plate 2, providing a stable installation position for the spray pump 11 and ensuring the stability of the spray pump 11 when extracting and spraying pollen. Multiple rotary propellers 21 are rotatably connected to the top of the shell 1. The rotary propellers 21 are key components for the drone to fly. The motor 8 drives the rotary propellers 21 to rotate, generating lift, enabling the drone to fly in the air and reach the designated pollination site. The bottom of the shell 1 is fixedly connected to the support legs 3, which provide support and cushioning during the take-off and landing of the drone. The system effectively protects the drone's fuselage and internal components, while ensuring the drone's stability on the ground and preventing it from tipping over. A camera 22 is fixedly connected to the bottom of the shell 1, which can capture the scene below the drone in real time. By viewing the footage captured by the camera 22, operators can understand the drone's flight status, the pollination area, and the distribution of flowers, thereby better controlling the drone's flight path and pollination operations, and improving the accuracy and efficiency of pollination. The front end of the input pipe 5 is fixedly connected to the rear end of the fixed box 6. This connection method ensures that pollen can smoothly enter the fixed box 6 from the pollen storage box 4 through the input pipe 5, preparing for subsequent pollen flow adjustment and spraying.
[0035] Reference Figure 1 , Figure 2 and Figure 4The docking assembly includes a connecting pipe 13, the rear end of which is fixedly connected to the front end of the spray pump 11. A connecting pipe 14 is slidably connected inside the connecting pipe 13. The connecting pipe 13 is a crucial component connecting the spray pump 11 and the connecting pipe 14, providing a channel for the installation and sliding of the connecting pipe 14, while also ensuring the sealing of the entire docking process. Multiple sliding teeth 15 are fixedly connected to the outside of the connecting pipe 14. A rotating block 16 is threadedly connected to the outside of the connecting pipe 13. A limiting block 17 is fixedly connected inside the rotating block 16. The rotating block 16 is threadedly connected to the outside of the connecting pipe 13. When the operator rotates the rotating block 16, the position of the limiting block 17 can be adjusted, thereby controlling the connection. The sliding and fixing of the connecting pipe 14 is a simple and convenient connection method that enables quick installation and disassembly of the spray head 20. The main function of the limiting block 17 is to restrict the movement of the sliding teeth 15. When the rotating block 16 rotates, the limiting block 17 will rotate with it, thereby restricting and releasing the connecting pipe 14. This ensures that the connecting pipe 14 can be stably fixed inside the connecting pipe 13 when needed and can be easily removed when disassembly is required. The limiting block 17 and the connecting pipe 13 have a sliding groove 18 inside. The sliding groove 18 provides a track for the sliding teeth 15, allowing the connecting pipe 14 to slide in a specific direction inside the connecting pipe 13, ensuring the accuracy and stability of the installation and disassembly process.
[0036] The connecting pipe 13 is internally fixedly connected with a sealing gasket 19. After the connecting pipe 14 is installed, the sealing gasket 19 fits tightly against the outside of the connecting pipe 14, forming a good seal to prevent pollen leakage during transport and ensure the normal operation of pollination. The connecting pipe 14 is externally fixedly connected with a spray head 20, which is the component that ultimately sprays pollen onto the flowers. Its design directly affects the pollen spraying effect and the success rate of pollination. Through its cooperation with the docking assembly, it can be easily cleaned and replaced to maintain good spraying performance. The sliding tooth 15 is externally slidably connected to the inside of the sliding groove 18. This sliding connection allows the connecting pipe 14 to slide smoothly inside the connecting pipe 13. The rear end of the connecting pipe 14 is connected to the outside of the sealing gasket 19. When the connecting tube 14 is installed in place, its rear end makes tight contact with the sealing gasket 19 to form a seal, ensuring that pollen will not leak from the connection between the connecting tube 14 and the connecting tube 13. The rear end of the limiting block 17 makes contact with the front end of the sliding tooth 15. When the rotating block 16 rotates and causes the limiting block 17 to move, the rear end of the limiting block 17 will contact or separate from the front end of the sliding tooth 15, thereby fixing and releasing the connecting tube 14. This design can quickly and effectively control the state of the connecting tube 14, making it convenient for operators to operate. The external sliding connection of the connecting tube 14 is inside the limiting block 17, ensuring the stability and accuracy of the connecting tube 14 during the sliding process, so that operators can accurately install the connecting tube 14 to the designated position and easily remove it when needed.
[0037] Working principle: When operators need to use drones for pollination, they store pollen inside the pollen storage box 4, then start the drone to go to the designated location for pollination. By starting the spray pump 11, the pollen inside the pollen storage box 4 is extracted and sprayed out through the spray head 20 to pollinate the flowers. The operator can adjust the amount of pollen sprayed as needed according to the density of flowers in different scenarios. By starting the motor 8, the motor 8 drives the rotating disk 7 to rotate inside the fixed box 6, thereby adjusting the flow between the input pipe 5 and the output pipe 10, thus adjusting the pollen flow rate to meet the pollination needs of different scenarios and avoid pollen waste.
[0038] When the operator needs to clean or replace the spray head 20, first rotate the rotating block 16 to move it outside the connecting pipe 13, thereby removing the restriction block 17 from restricting the sliding teeth 15. When the sliding groove 18 inside the connecting pipe 13 and the sliding groove 18 inside the restriction block 17 are connected, the connecting pipe 14 can be removed from the inside of the connecting pipe 13, completing the disassembly of the spray head 20 for easy cleaning and replacement. When installing the spray head 20, slide the outside of the connecting pipe 14 back into the two sliding grooves 18 and fit it against the sealing gasket 19. Then rotate the rotating block 16 in the opposite direction to fit the outside of the connecting pipe 14 against the outside of the sealing gasket 19, restricting the movement of the connecting pipe 14 and achieving a quick sealing connection, reducing operation time and improving work efficiency.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
