Description

Technical Field

[0001] This utility model relates to the field of drone spraying device technology, and in particular to a pesticide spraying device for agricultural drones. Background Technology

[0002] Pesticide application is a crucial measure in agricultural plant protection, involving frequent and labor-intensive operations. It also poses certain toxic risks to humans, making it a demanding task in agricultural production. Currently, the use of drones for pesticide spraying has entered practical application, offering convenience and efficiency, and is widely welcomed. However, existing drone-driven pesticide spraying devices have limited spraying area, requiring repeated use and reducing efficiency. Therefore, we propose an agricultural drone-based pesticide spraying device. Utility Model Content

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a pesticide spraying device for agricultural drones.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a pesticide spraying device for an agricultural drone, comprising a drone body, wings, propellers, a support frame, and a water tank. The bottom of the drone body is assembled with a water tank. A pump box, communicating with the interior of the water tank, is installed at the bottom of the water tank. A conduit is installed at the bottom of the pump box, and a delivery pipe is provided at the bottom of the conduit. The conduit and the delivery pipe are rotatably connected via a bearing ring. A spray pipe is connected to the bottom of the delivery pipe. A gear sleeve is fitted around the delivery pipe. A protective box is installed at the bottom of the water tank. A motor and a power module are installed inside the protective box. An output shaft, penetrating the protective box, is driven by the motor's output shaft. The output shaft and the gear sleeve are driven by a drive belt, and the inner side of the drive belt meshes with the teeth of the gear sleeve.

[0005] Preferably, when the pump box at the bottom of the water tank is started, it supplies liquid to the spray pipe through the delivery pipe in a spraying state.

[0006] Preferably, when the motor starts and drives the output shaft to rotate, the output shaft drives the gear sleeve to rotate through the drive belt, and the delivery pipe drives the spray pipe to rotate and spray through the gear sleeve.

[0007] Preferably, the water tank is equipped with several sets of equidistant mesh frames inside, and the inner side of the mesh frames is provided with a buffer mesh to buffer the flow of water.

[0008] Preferably, when the water source inside the water tank is shaken and passes through the buffer net inside the mesh frame, the water source flows in a gradual and buffered state through the buffer net.

[0009] This utility model provides a pesticide spraying device for agricultural drones. It has the following beneficial effects:

[0010] 1. A pesticide spraying device for an agricultural drone. In this paper, after the main body of the drone starts and drives the water tank to fly, the pump box can be started to transport the liquid inside the water tank through the conduit to the delivery pipe. The delivery pipe then sprays the liquid out through the spray pipe. When the motor inside the protection box starts, the motor can drive the drive belt to rotate through the output shaft. The teeth on the inner side of the drive belt then drive the spray pipe at the bottom of the delivery pipe to rotate through the gear sleeve, so that the liquid sprayed out by the spray pipe is thrown out in all directions, increasing the spray irrigation area, thereby improving the working efficiency of the device.

[0011] 2. The pesticide spraying device for an agricultural drone has a water tank with a mesh frame inside, and a buffer net inside the mesh frame. When the drone moves and the water tank moves, the water inside the tank shakes. After passing through the buffer net inside the mesh frame, the water flows in a buffered state. The multiple sets of buffer nets are spaced close together, which reduces the impact resistance of the liquid flow, thereby reducing liquid resistance and ensuring the flight stability of the drone.

[0021] 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.

[0022] Example: A pesticide spraying device for an agricultural drone, such as Figures 1-5 As shown, the drone includes a main body 1, wings 2, propellers 3, support frame 4, and water tank 5. The water tank 5 is assembled at the bottom of the main body 1. A pump box 6, which communicates with the interior of the water tank 5, is installed at the bottom of the water tank 5. A conduit 7 is installed at the bottom of the pump box 6. A delivery pipe 8 is provided at the bottom of the conduit 7. The conduit 7 and the delivery pipe 8 are rotatably connected by a bearing ring 9. A spray pipe 10 is connected to the bottom of the delivery pipe 8. A gear sleeve 11 is fitted on the outside of the delivery pipe 8. A protective box 12 is installed at the bottom of the water tank 5. A motor 13 and a power module 15 are installed inside the protective box 12. An output shaft 14, which passes through the protective box 12, is driven and connected to the output shaft 14 at the output shaft end of the motor 13. The output shaft 14 and the gear sleeve 11 are driven and fitted by a drive belt 16. The inner side of the drive belt 16 is engaged with the gear sleeve 11 by teeth 17. Several sets of equidistantly distributed mesh frames 18 are installed inside the water tank 5. A buffer net 19 is provided on the inner side of the mesh frames 18 to buffer the flow of water.

[0023] Furthermore, when the pump box 6 at the bottom of the water tank 5 is started, it supplies liquid to the spray pipe 10 through the delivery pipe 8.

[0024] Furthermore, when the motor 13 starts and drives the output shaft 14 to rotate, the output shaft 14 drives the gear sleeve 11 to rotate through the drive belt 16, and the delivery pipe 8 drives the spray pipe 10 to rotate and spray through the gear sleeve 11.

[0025] Furthermore, when the water inside the water tank 5 is shaken and passes through the buffer net 19 inside the mesh frame 18, the water flows through the buffer net 19 in a gradual buffering state.

[0026] The working principle of this utility model:

[0027] After the main body of the drone 1 starts and drives the water tank 5 to fly, the pump box 6 can start to transport the liquid inside the water tank 5 to the delivery pipe 8 through the conduit 7. The delivery pipe 8 then sprays the liquid out through the spray pipe 10. When the motor 13 inside the protection box 12 starts, the motor 13 can drive the drive belt 16 to rotate through the output shaft 14. The teeth 17 on the inner side of the drive belt 16 then drive the spray pipe 10 at the bottom of the delivery pipe 8 to rotate through the gear sleeve 11, so that the liquid sprayed out by the spray pipe 10 is thrown out in all directions, increasing the spray irrigation area and thus improving the working efficiency of the device. When the main body of the drone 1 drives the water tank 5 to fly and move, when the water source inside the water tank 5 is shaking, the water source passes through the buffer net 19 inside the mesh frame 18 and the water source is in a buffered flow state through the buffer net 19. Moreover, the multiple sets of buffer nets 19 are closely spaced, reducing the impact resistance of the liquid flow.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
