Description

Technical Field

[0001] This utility model relates to the field of drone spraying technology, specifically to a plant protection drone spraying device. Background Technology

[0002] Agricultural drones are unmanned aerial vehicles used for the protection of agricultural and forestry plants. These drones consist of three parts: a flight platform (fixed-wing, helicopter, or multi-rotor aircraft), a navigation and flight control system, and a spraying mechanism. They can spray pesticides, seeds, powders, etc., through ground remote control or navigation and flight control.

[0003] Currently, most agricultural drone spraying devices on the market operate by spraying through vertically downward nozzles. While this achieves the desired spraying effect, it also has the following drawbacks: the nozzle position and angle are fixed, making it impossible to adjust the nozzle angle according to the actual situation. Additionally, the nozzles are exposed to the external environment, and during drone loading, operators often accidentally touch the nozzles due to improper operation. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments: In the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a plant protection drone spraying device includes a pesticide tank 1, and also includes: The filling tube 2 is inserted and installed on the top of the medicine tank 1, and is used to add medicine into the medicine tank 1; A sealing plug 3 is inserted into the top of the filling tube 2, and the outer wall of the sealing plug 3 is evenly covered with anti-slip texture. A water pump 24 is fixedly installed on the outside of the medicine box 1. A water pump 25 is connected to the top of the water pump 24. The other end of the water pump 25 passes through the top of the medicine box 1 and extends into the medicine box 1. A flexible conduit 26 is connected to the bottom of the water pump 24. The other end of the flexible conduit 26 is connected to the hollow tube 9. Mounting bracket 4 is provided in two sets and is fixedly installed on both sides of the outer wall of medicine box 1; The fixing frame 6 has a U-shaped structure. The left and right sides of the fixing frame 6 are fixedly connected to the outer wall of the medicine box 1, respectively. The bottom of the fixing frame 6 is provided with a through groove 7, and the side groove 8 is provided on the side of the through groove 7 near the water pump. Hollow tube 9 is movably connected to the left and right sides of fixed frame 6, and nozzle 10 is installed at the bottom of hollow tube 9; A rotating assembly for connection to the hollow tube 9; The protective component is located on one side of the hollow tube 9.

[0021] The medicine tank 1 is mounted on the drone via the mounting bracket 4. The side groove 8 provides space for the flexible conduit 26 to move. The hydraulic pressure in the medicine tank 1 is delivered to the hollow tube 9 via the water pump 24. The angle of the nozzle 10 is adjusted by rotating the hollow tube 9 via the rotating component, so as to achieve spraying in different directions. After spraying is completed, the nozzle 10 is located at the protective component to protect the nozzle 10.

[0022] In the embodiments, such as Figure 1 , Figure 3 As shown, the outer wall of the medicine tank 1 is provided with a fixing sleeve 27, and the water pump 24 is mounted on the fixing sleeve 27. The fixing sleeve 27 is used to fix the water pump 24 to the outer wall of the medicine tank 1, making the water pump 24 more stable during subsequent operation.

[0023] In the embodiments, such as Figure 3 , Figure 4 , Figure 5 As shown, the rotating assembly includes two circular shafts 11. One end of each shaft 11 is fixedly connected to the outer wall of the hollow tube 9, and the other end is rotatably connected to the outer wall of the fixed frame 6. Gears 12 are connected to both shafts 11, and each gear 12 is equipped with a rack 13. Side frames 16 are fixedly connected to both sides of the inner wall of the fixed frame 6. A first electric push rod 14 is fixedly mounted on each side frame 16. The telescopic ends of the two first electric push rods 14 are fixedly connected to the outer walls of the two racks 13. The rotating assembly allows for angle adjustment of the nozzle 10, enabling spraying operations at various angles according to actual conditions.

[0024] In the embodiments, such as Figure 4 , Figure 5 As shown, guide blocks 18 are fixedly connected to each of the two racks 13 on opposite sides, and guide rods 17 for cooperating with the guide blocks 18 are fixedly installed on the side frame 16. By utilizing the cooperation between the guide blocks 18 and the guide rods 17, the horizontal movement trajectory of the racks 13 is limited, thereby improving stability.

[0025] In the embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the protective assembly includes a connecting plate 19, which is fixedly connected between two side frames 16. A second electric push rod 20 is fixedly installed on the inner wall of the connecting plate 19, and a protective shell 21 is fixedly installed on the telescopic end of the second electric push rod 20. The second electric push rod 20 pushes the protective shell 21 to cover and protect the nozzle 10, preventing the nozzle 10 from being accidentally touched and damaged.

[0026] In the embodiments, such as Figure 3 , Figure 4 , Figure 5 As shown, two limiting rods 22 are fixedly connected to the outer wall of the protective shell 21. One end of each limiting rod 22 passes through the connecting plate 19 and is movably connected to the connecting plate 19. A limiting block 23 is fixedly connected to one end of each limiting rod 22. This limits the movement trajectory of the protective shell 21 and provides a certain degree of support, ensuring its stable performance.

[0027] In the embodiments, such as Figure 5 As shown, each of the two electric actuators 14 and the second electric actuator 20 is fixedly mounted with a mounting base 15. The three mounting bases 15 are respectively fixedly connected to the inner wall of the connecting plate 19 and the inner walls of the two side frames 16. The mounting bases 15 ensure the stable operation of the electric actuators 14 and 20.

[0028] In the embodiments, such as Figure 1 , Figure 2 As shown, a transparent window 5 is embedded in the outer wall of the medicine box 1. The transparent window 5 allows the remaining amount of medicine inside the medicine box 1 to be directly viewed when the drone lands.

[0029] Working principle: The medicine tank 1 is installed on the drone via the mounting bracket 4. First, the sealing plug 3 is removed, and liquid medicine is added into the filling tube 2. Then, the sealing plug 3 is used to seal the filling tube 2. Subsequently, the agricultural drone is used to carry the medicine tank 1 and other components into the air. When it reaches a suitable position, the water pump 24 is driven, so that the water pump 24 draws the liquid medicine from the inside of the medicine tank 1 through the water suction pipe 25, and then injects the liquid medicine into the hollow tube 9 through the soft tube 26. Finally, it is sprayed out through multiple nozzles 10 to realize the spraying operation on the plants. When it is necessary to adjust the spray angle of the nozzle 10, the two No. 1 electric push rods 14 are driven synchronously, so that the two No. 1 electric push rods 14 push the corresponding racks 13 to move, the two racks 13 push the gears 12 to rotate, the two gears 12 drive the two round shafts 11 to rotate, the two round shafts 11 together drive the hollow tube 9 to rotate, and the hollow tube 9 drives multiple nozzles 10 to rotate, so as to achieve the purpose of adjusting the spray angle of the nozzle 10. After adjustment, the No. 1 electric push rod 14 can be closed, and the No. 1 electric push rod 14 achieves self-locking. When parking is required, the first electric push rod 14 is driven to deflect the nozzle 10 toward the protective shell 21, and the second electric push rod 20 is driven so that the second electric push rod 20 pushes the protective shell 21 to cover the outside of the multiple nozzles 10, hiding the nozzles 10 inside the protective shell 21 and providing them with protection.

[0030] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
