Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a precision fertilization and spraying device for agricultural UAVs. Background Technology

[0002] With the maturity of drone technology, more and more industries are adopting drones to replace manual labor.

[0003] Existing technology disclosure document CN220483549U provides a high-efficiency fertilization and pesticide spraying drone. In this device, a water pump draws pesticide solution from the pesticide chamber and delivers it to the nozzle for spraying. Simultaneously, by activating the drive motor, a baffle plate rotates. If the baffle plate moves away from the fertilizer orifice, fertilizer from the fertilizer chamber falls, initiating fertilization. This allows the device to perform fertilization and pesticide spraying simultaneously, improving the drone's operational efficiency and enhancing its functionality. Furthermore, the coordination between the baffle plate and the spray chamber guides the falling fertilizer, further improving efficiency.

[0004] The fertilization range has been expanded, further improving the efficiency of agricultural drone fertilization operations.

[0005] Although the existing technical solutions described above can achieve the relevant beneficial effects through the structure of the existing technology, they still have the following defects: there is compression between the fertilizers accumulated inside the fertilizer chamber, which makes it impossible to ensure that the fertilizers inside the fertilizer chamber can be smoothly discharged through the spraying chamber.

[0006] In light of this, we propose an agricultural drone precision fertilization and spraying device. Utility Model Content

[0010] By adopting the above technical solution, when the auger paddle is driven by the drive motor to uniformly discharge the fertilizer, the discharged fertilizer falls to the bottom of the fertilizer cylinder and is stably discharged under the action of the feeding paddle, ensuring the stability of fertilizer discharge inside the fertilizer cylinder.

[0011] As an optional solution to the technical solution of this application, the spraying assembly includes a foldable and retractable cartridge. A liquid guide tube is fixedly connected to one side of the cartridge, and a turbine component is fixedly connected to the other end of the liquid guide tube.

The manifold sleeve is fixedly connected to the outside of the turbine component, and a spray pipe is rotatably connected inside the manifold sleeve. The spray pipe is fixedly connected to the shaft end of the turbine component.

[0012] By adopting the above technical solution, the turbine component can be driven by the rotation of the feeding paddle to generate suction, thereby realizing the suction and discharge of water inside the cartridge. The foldable and retractable cartridge can provide a shock-resistant buffer effect for the cartridge structure, ensuring the stability of the device.

[0013] As an optional solution to the technical solution in this application, a tension spring is fixedly connected inside the cartridge case.

[0014] By adopting the above technical solution, the tension spring can provide folding force to the foldable and retractable cartridge, so that the cartridge structure can be folded and stored.

[0015] As an optional solution to the technical solution in this application, a fence ring is fixedly connected to the bottom end of the fertilizer cylinder.

[0016] By adopting the above technical solution, the spray pipe can be protected by the fence ring to avoid crushing damage during the take-off and landing of the machine.

[0017] As an optional solution to the technical solution in this application, a soft brush is fixedly connected to the outside of the feeding paddle.

[0018] By adopting the above technical solution, the soft brush can ensure that the material leakage hole is clean when the feeding paddle spreads fertilizer, thus ensuring the smooth discharge of material from the leakage hole.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application utilizes a drive motor to drive the auger paddle to uniformly discharge fertilizer, causing the discharged fertilizer to fall at the bottom of the fertilizer cylinder and be stably discharged under the action of the feeding paddle, thus ensuring the stability of fertilizer discharge inside the fertilizer cylinder.

[0021] 2. This application utilizes the suction force generated by the turbine component driven by the rotating feed paddle to achieve the suction and discharge of water inside the cartridge. The foldable and retractable cartridge provides a shock-resistant cushioning effect for the cartridge structure, ensuring the stability of the device during use. Attached Figure Description

The material blocking hopper 7 is fixedly connected inside the fertilizer cylinder 4, and a material pushing paddle 8 is fixedly connected to one end of the auger paddle 6.

[0028] This agricultural drone precision fertilization and spraying device uses a drive motor 5 to drive the auger propeller 6 to uniformly release fertilizer. The discharged fertilizer falls at the bottom of the fertilizer cylinder 4 and is stably discharged under the action of the feeding paddle 8, ensuring the stability of fertilizer discharge inside the fertilizer cylinder 4.

The manifold sleeve 34 is fixedly connected to the outside of the turbine component 33, and a spray pipe 35 is rotatably connected inside the manifold sleeve 34. The spray pipe 35 is fixedly connected to the shaft end of the turbine component 33. A tension spring is fixedly connected inside the cartridge 31.

[0030] This agricultural drone precision fertilization and spraying device utilizes the rotating feed paddle 8 to drive the turbine component 33 to generate suction, thereby achieving the suction and discharge of water inside the cartridge 31. The foldable and retractable cartridge 31 provides a shock-resistant cushioning effect for the cartridge structure, ensuring the stability of the device during use. The tension spring provides folding force to the foldable and retractable cartridge 31, allowing the cartridge structure to be folded and stored.
