Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle equipment, in particular to a novel multifunctional liquid fertilizer spraying unmanned aerial vehicle equipment. Background Art

[0002] Liquid fertilizer is a plant nutrient supplement in liquid form, commonly used to promote plant growth and increase crop yields. It contains a variety of nutrients such as nitrogen, phosphorus, potassium, and trace elements, and can be quickly absorbed by plants. Traditional manual or mechanical fertilization methods usually require a lot of manpower and time. Therefore, when spraying fertilizer over large areas or in areas with complex terrain or difficult to reach, drones are often used. Drones can quickly cover large areas of farmland, significantly improving fertilization efficiency and completing fertilization tasks in a short time, saving labor costs and time, effectively improving fertilization efficiency and accuracy, and promoting the intelligent and sustainable development of agriculture.

[0003] Traditional spraying drones are usually composed of two main parts: the drone body and the spraying system. The drone body includes the fuselage, power system, and navigation equipment, which is responsible for flight stability and precise positioning; while the spraying system consists of nozzles and fertilizer tanks, which are responsible for evenly spraying liquid fertilizer onto crops.

[0004] However, the nozzles and fertilizer tanks of traditional spraying drones are usually small, which limits the amount of fertilizer they can hold during flight spraying. Spraying drones often need to fertilize large areas of farmland. Therefore, when the fertilizer stock is insufficient during flight, the drone needs to be frequently recalled to add fertilizer. The process is cumbersome and time-consuming. Moreover, when fertilizing, the fertilizer in the tank cannot be continuously stirred, which can easily cause the fertilizer to precipitate in the tank to form lumps or sediments, which in turn affects the uniformity of the fertilizer during spraying. Therefore, a new type of liquid fertilizer multifunctional spraying drone equipment is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1-4 The utility model provides an embodiment: a new liquid fertilizer multifunctional spraying drone device, including a frame 1, which provides a stable support structure for the drone, can bear the weight of all components and ensure that it maintains balance during flight, a motor 2 is fixedly connected to the top of the frame 1, and the motor 2 is responsible for providing power to ensure that the propeller 3 generates sufficient lift during flight to push the drone to move flexibly in the air, the output end of the motor 2 is fixedly connected to the propeller 3, the bottom of the frame 1 is fixedly connected to the support frame 4, and the support frame 4 is internally provided with a landing gear 5, which can land stably on different terrains and reduce damage to the ground, the bottom of the frame 1 is fixedly connected to the fixing frame 6, and the bottom of the fixing frame 6 is provided with a storage assembly, which is used to store and transport fertilizer;

[0033] The storage assembly includes a support plate 7 and a storage box 8. The support plate 7 is fixedly connected to the bottom of the fixed frame 6, and the storage box 8 is fixedly connected to the top of the support plate 7 to form a closed container for storing liquid fertilizer to prevent leakage and evaporation. An electric valve 9 is fixedly connected to one side of the storage box 8 to control the flow of fertilizer and ensure the working state of the feeding pipe 10. The output end of the electric valve 9 is fixedly connected to the feeding pipe 10, and one end of the feeding pipe 10 is fixedly connected to the storage tank 11. The storage tank 11 is fixedly connected to the discharge pipe 12. The support plate 7 is fixedly connected to the connecting frame 15. One side of the connecting frame 15 is fixedly connected to a motor 16. The output end of the motor 16 is fixedly connected to an agitator 17. One 16 is responsible for driving the rotation of the agitator 17 so that the liquid fertilizer in the storage tank 11 can be fully mixed to maintain its good spraying effect. The agitator 17 is rotatably connected to the inside of the storage tank 11. A driving assembly is provided on one side of the connecting frame 15. The driving assembly is used to drive the storage tank 11 to rotate. The agitator 17 is rotatably connected to the inside of the connecting column 18. A discharge pipe 12 is fixedly connected to the inside of the storage tank 11. One end of the discharge pipe 12 is fixedly connected to an electric valve 2 13. The discharge pipe 12 is connected to the electric valve 2 13 through a sealing connection. The electric valve 2 13 controls the spraying of the liquid fertilizer. The output end of the electric valve 2 13 is fixedly connected to the nozzle 14, which is responsible for evenly spraying the fertilizer into the farmland.

[0034] Specifically, when using the fertilizer spraying drone equipment, the fertilizer is first injected into the storage box 8 for storage to prevent the drone from running out of fertilizer during flight. Then, after the drone takes off, the electric valve 9 is started during flight to feed the fertilizer in the storage box 8 into the feeding pipe 10. The feeding pipe 10 ensures that the fertilizer enters the storage tank 11. The storage tank 11 is provided with an output end of a motor 16, and the stirrer 17 driven by the motor rotates rapidly in the tank, so that the stirrer 17 can effectively stir the fertilizer, thereby ensuring that the fertilizer is fully mixed. The design of the stirrer 17 includes multiple stirring blades to improve the mixing efficiency and avoid fertilizer agglomeration or precipitation. When the fertilizer mixing is completed, the electric valve 2 13 is opened to allow the fertilizer to flow smoothly into the discharge pipe 12. Finally, the fertilizer passing through the discharge pipe 12 falls into the nozzle 14, thereby achieving the fertilization effect, so that the spraying drone can continuously and stably supply fertilizer during flight, effectively improving the fertilization efficiency and ensuring the full utilization of the fertilizer.

[0035] Reference Figure 3-Figure 5The driving assembly includes a motor 2 19 and a rotating column 20. The motor 2 19 is fixedly connected to one side of the connecting frame 15 to ensure its stability during operation. The rotating column 20 is fixedly connected to the output end of the motor 2 19 so that the power of the motor 2 19 can be effectively transmitted to the rotating column 20. The outer wall of the rotating column 20 is fixedly connected to a turntable 21, providing a wide operating surface, which is convenient for attaching other components or tools to work. The outer wall of the connecting column 18 is fixedly connected to a support column 22, and the outer wall of the support column 22 is rotatably connected to a rotating frame 23 to adapt to different working angle requirements, further improving the flexibility and applicability of the equipment. A transmission column 24 is fixedly connected to one side of the rotating frame 23, and the transmission column 24 is rotatably connected to the inside of the turntable 21. Driven by the motor 2 19, the turntable 21 can drive the transmission column 24 to rotate.

[0036] Specifically, during the spraying process, the output end of the motor 2 19 can effectively drive the rotating column 20 to rotate. When the rotating column 20 is driven by the motor 2 19, it will generate a rotational torque and drive the turntable 21 connected to the outer wall to rotate. After the turntable 21 rotates, the transmission column 24 inside it also moves accordingly. Through the connection structure with the turntable 21, it can effectively transmit the rotational force to the rotating frame 23 on one side. The rotating frame 23 has a swinging function and can swing left and right near a fixed point. When the rotating frame 23 is subjected to force, it not only drives the internal support column 22 to move, but also enables the support column 22 to generate a corresponding dynamic response after being subjected to force, thereby realizing effective motion transmission and motion conversion.

[0037] Reference Figure 3-Figure 5 One end of the storage tank 11 is fixedly connected to a connecting column 18, and the connecting column 18 is rotatably connected to one side of the connecting frame 15, so that the storage tank 11 can swing freely within a certain range, further improving the transportation efficiency and adaptability of the fertilizer.

[0038] Specifically, one end of the support column 22 is connected to the connecting column 18, and the connecting column 18 rotates on the other side of the connecting frame 15. The rotation of the connecting column 18 further drives the storage tank 11 connected to one end to rotate. Through the rotation of the storage tank 11, the discharge pipe 12 and the nozzle 14 will swing left and right accordingly. The connection between the discharge pipe 12 and the nozzle 14 adopts a joint design so that it remains stable and not easy to fall off during movement, so that the spraying angle of the nozzle 14 can be precisely adjusted. This adjustable spraying angle ensures that a wider range can be covered during fertilization, effectively realizes precise fertilization, meets the fertilization needs of different crops, and thus improves the efficiency and effectiveness of agricultural production.

[0039] Working principle: When using the fertilizer spraying drone equipment, first inject the fertilizer into the storage box 8 for storage to prevent insufficient fertilizer during the flight of the drone, and then start the electric valve 19 during flight to send the fertilizer in the storage box 8 into the feeding pipe 10, and then send the fertilizer into the storage tank 11 through the feeding pipe 10. At this time, the agitator 17 can be driven by the output end of the motor 16 to rotate inside the storage tank 11, so that the agitator 17 stirs the fertilizer and mixes it fully. After the mixing is completed, the electric valve 2 13 is opened to allow the fertilizer to flow into the discharge pipe 12 and fall into the nozzle 14 through the discharge pipe 12, so that the nozzle 14 sprays the fertilizer, thereby achieving the effect of maintaining the supply of fertilizer during the flight. During the spraying process, the output end of the motor 2 19 can be used to drive the rotating column 20 to rotate. The rotating column 20 is forced to drive the turntable 21 connected to the outer wall to rotate. The turntable 21 is forced to drive the internal transmission column 24 to move, so that the transmission column 24 drives the rotating frame 23 connected on one side to swing left and right. The rotating frame 23 is forced to drive the internal support column 22 to move. The support column 22 is forced to drive the connecting column 18 connected at one end to rotate on the side of the connecting frame 15, thereby causing the connecting column 18 to drive the storage tank 11 connected at one end to rotate. Through the rotation of the storage tank 11, the discharge pipe 12 and the nozzle 14 are caused to swing left and right accordingly, thereby adjusting the spraying angle of the nozzle 14, thereby achieving the effect of adjusting the spraying angle to expand the spraying range.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
