Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and more specifically, to a fertilizer diffuser for unmanned aerial vehicles (UAVs). Background Technology

[0002] With the development of modern agriculture, the requirements for fertilizer application efficiency and precision are becoming increasingly stringent. Precision fertilization technology can achieve precise fertilizer delivery and improve fertilizer utilization. Drone technology, due to its high efficiency, precision, and flexibility, has been widely used in agriculture. The physicochemical properties of fertilizers, such as specific gravity, angle of repose, and bulk density, have a significant impact on the effectiveness of drone dispersal.

[0003] In practical use, traditional drone fertilizer spreading devices directly throw fertilizer outwards, and the fertilizer particles move along a single trajectory, resulting in some areas being densely distributed and others sparsely distributed on the farmland. This can lead to localized over- or under-fertilization, causing uneven crop growth and resulting in differences in crop growth. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drone fertilizer diffuser to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A drone fertilizer diffuser includes a drone body, a storage box fixedly connected to one side of the drone body, a feed inlet connected to the top of the storage box, a connecting shell connected to the bottom of the storage box, a diffusion component installed on the connecting shell, and a metering mechanism installed inside the storage box. The diffusion assembly includes a stepper motor installed inside a connecting housing. A feeding ramp is provided at the top of the connecting housing. A gear is fixedly connected to the output end of the stepper motor. A gear is meshed with a gear plate on one side of the gear. A dispersing cylinder is fixedly connected inside the gear plate. The dispersing cylinder is rotatably connected to the inside of the connecting housing. A discharge chamber is provided inside the dispersing cylinder. Three discharge pipes are connected to the outside of the dispersing cylinder. One end of each of the three discharge pipes is connected to the inside of the discharge chamber. A diffusion port is fixedly connected to one end of each discharge pipe. The cross-section of the diffusion port is conical.

[0006] By adopting the above technical solution, the fertilizer can be diffused outward in a concentric circle pattern by the reciprocating swing of the spreading cylinder, thereby optimizing the uniformity of application.

[0007] As a further description of the above technical solution: the quantitative mechanism includes an electric push rod, which is installed inside the storage box. A push plate is fixedly connected to the output end of the electric push rod. A plurality of inclined slots are opened on one side of the push plate, and the inclined slots are inclinedly arranged on one side of the push plate. A baffle is fixedly connected to the top of the push plate. A first inclined plate and a second inclined plate are fixedly connected inside the storage box. The second inclined plate and the first inclined plate are symmetrically distributed inside the storage box.

[0008] By adopting the above technical solution, fertilizer can be quantitatively delivered to the discharge chamber inside the spreading cylinder, so that the fertilizer is spread more evenly each time.

[0009] The technical effects and advantages of this utility model are as follows: 1. By setting up a diffusion component, compared with the existing technology, the reciprocating swing of the spreading cylinder generates centrifugal force, causing fertilizer particles to be thrown outward along the three discharge pipes at the edge of the discharge chamber. The conical effect of the diffusion port can guide the fertilizer to diffuse outward, so that the fertilizer is distributed and diffused in a concentric circle pattern, thereby expanding the fertilization area and further optimizing the uniformity of spreading. 2. By setting up a quantitative mechanism, compared with the existing technology, a portion of the fertilizer can be pushed into the discharge slope using a pusher plate, and a baffle is used to block it during the pushing process. This makes the fertilizer more evenly distributed with each push. The inclined design of multiple inclined troughs optimizes the downward flow of fertilizer, so that the fertilizer is more evenly distributed with each application of the spreading cylinder and the fertilizer is more evenly distributed in the farmland, thereby improving the fertilizer utilization rate.

[0017] 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.

[0018] The embodiments disclosed in this application are as follows: Figure 1-6 The drone fertilizer diffuser shown includes a drone body 1, a storage box 2 fixedly connected to one side of the drone body 1, a feed inlet 3 connected to the top of the storage box 2, a connecting shell 4 connected to the bottom of the storage box 2, a diffusion component installed on the connecting shell 4, and a metering mechanism installed inside the storage box 2. The diffusion assembly includes a stepper motor 6, which is installed inside the connecting housing 4. A feeding ramp 5 is provided at the top of the connecting housing 4. A gear 7 is fixedly connected to the output end of the stepper motor 6. A gear 8 meshes with one side of the gear 7. A dispersing cylinder 9 is fixedly connected inside the gear 8 and is rotatably connected to the inside of the connecting housing 4. A discharge chamber 10 is provided inside the dispersing cylinder 9. Three discharge pipes 11 are connected to the outside of the dispersing cylinder 9. One end of each of the three discharge pipes 11 communicates with the inside of the discharge chamber 10, and one end of each discharge pipe 11 is fixedly connected to... There is a diffuser 12 with a conical cross-section. The stepper motor 6 drives the gear 7 to rotate back and forth, so that the gear 7 can mesh and drive the gear disk 8 to rotate. This allows the spreading cylinder 9 to swing back and forth inside the connecting shell 4. During the rotation of the spreading cylinder 9, centrifugal force is generated. The centrifugal force causes the fertilizer particles to be thrown outward along the three discharge pipes 11 at the edge of the discharge chamber 10, so that the fertilizer is distributed and diffused in a concentric circle pattern. This allows the area to be covered during the spreading process to be expanded, and the uniformity of the spreading can be further optimized.

[0019] Reference Figure 3As shown, the metering mechanism includes an electric push rod 13, which is installed inside the storage tank 2. A push plate 14 is fixedly connected to the output end of the electric push rod 13. Multiple inclined grooves 15 are opened on one side of the push plate 14, and the inclined grooves 15 are inclinedly arranged on one side of the push plate 14. A baffle 16 is fixedly connected to the top of the push plate 14. A first inclined plate 17 and a second inclined plate 18 are fixedly connected inside the storage tank 2. The second inclined plate 18 and the first inclined plate 17 are symmetrically distributed inside the storage tank 2. The electric push rod 13 pushes the push plate 14 to move, so that the push plate 14 can transport fertilizer to the discharge slope 5. When pushing, it can drive the baffle 16 to move, thereby pushing a metered amount of fertilizer. The inclined action of the multiple inclined grooves 15 can guide the fertilizer to tilt downward during the pushing process, which can optimize the downward flow of fertilizer. By pushing the fertilizer meteredly, the fertilizer is more evenly distributed by the spreading cylinder 9 each time, and in conjunction with the spreading cylinder 9, the fertilizer is evenly distributed in the farmland.

[0020] Working principle of this utility model: This utility model designs a drone fertilizer diffuser, the specific structure of which is shown in the attached instruction manual. Figure 1-6 As shown, in this technical solution, through the cooperation of various structures, when fertilizer needs to be spread by the drone body 1, the fertilizer is first transported into the storage box 2 through the feed inlet 3. Then, the drone body 1 is started, causing it to fly along a predetermined trajectory. After the fertilizer enters the storage box 2, the electric push rod 13 is activated by the external controller at regular intervals to push the push plate 14 to move. This allows the push plate 14 to push some of the fertilizer onto the discharge ramp 5. Utilizing the downward tilting action of multiple discharge ramps 5, the fertilizer that can be pushed can tilt downwards, thus facilitating the rapid pushing of the fertilizer onto the discharge ramp 5. At the same time, the push plate 14 can drive the baffle 16 to move below the first inclined plate 17 and the second inclined plate 18. Through the baffle 16, The fertilizer is blocked from above, so that the fertilizer flow that the pusher plate 14 can push each time is more uniform. The inclined design of the feed ramp 5 allows the pushed fertilizer to fall into the discharge chamber 10 inside the spreading cylinder 9. Then the stepper motor 6 is started, and the stepper motor 6 drives the gear 7 to rotate back and forth. The gear 7 can mesh and drive the gear plate 8 to rotate, so that the spreading cylinder 9 can swing back and forth inside the connecting shell 4. The three discharge pipes 11 are connected to the spreading cylinder 9 and extend to the inside of the discharge chamber 10. The fertilizer inside the discharge chamber 10 can be transported to the inside of the discharge pipes 11 by the action of centrifugal force. The conical opening of the diffuser 12 allows the fertilizer to diffuse outward when it is discharged, so as to cover the target fertilization area.
