Description

Technical Field

[0001] This utility model relates to the field of agricultural planting and sowing technology, and in particular to a drone sowing device. Background Technology

[0002] A drone seeding device is an agricultural operation equipment that uses a drone as a platform and integrates functional modules such as seed storage and quantitative delivery. It achieves autonomous flight along a predetermined route through the drone's flight control system, and works with a dedicated sowing mechanism to evenly distribute seeds to the target farmland area according to set parameters. The overall design must meet the comprehensive requirements of lightweight, stability and operational efficiency, and is suitable for agricultural seeding operations under different terrain conditions.

[0003] The drone seeding device can effectively solve the limitations of traditional manual seeding and ground mechanical seeding, and greatly improve the efficiency and quality of agricultural seeding operations. During operation, the device can achieve full-area coverage seeding by setting a flight path according to the area, shape and crop variety of the farmland, avoiding the problems of missed seeding and double seeding that occur during manual seeding. Its onboard quantitative seeding system can accurately control the amount of seeds used per unit area, ensuring uniform seeding density and providing a good foundation for subsequent crop growth.

[0004] Currently available drone seeding devices struggle to control the seeding point in windy conditions, directly impacting seeding effectiveness. Because existing devices employ a semi-open design for their seeding mechanism, seeds, after being ejected from the nozzle, are directly affected by wind and deviate from their preset trajectory. This results in seeds not landing accurately at the target location, leading to seed accumulation in some areas and seedless areas in others. This uncontrolled seeding not only necessitates repeated seeding operations, significantly reducing efficiency, but also causes uneven crop growth due to uneven seed distribution. Furthermore, in strong winds, seeds may be blown away from the target field, resulting in seeding failure and losses in agricultural production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drone seeding device, which aims to improve the problem that the seed dispersal position deviates from the predetermined position in windy environments in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drone seeding device, including a fan housing, a rotary motor provided on the front side of the fan housing, a seed blowing mechanism provided at the bottom of the fan housing, the seed blowing mechanism being used to blow air onto the sown seeds to ensure precise seed landing point, and an anti-blocking storage mechanism provided at the bottom of the rotary motor, the anti-blocking storage mechanism being used to store the sown seeds while preventing the seed outlet from being blocked. The seed blowing mechanism includes an upper connecting ring, the bottom of which is fixedly connected to the top of the fan housing. A side heat sink is fixedly connected to the right side of the fan housing. A power connection cable is fixedly connected to the front side of the fan housing. A rotating fan is rotatably connected inside the fan housing. An air inlet assembly is provided at the top of the fan housing. A lower connecting rod is fixedly connected to the bottom of the fan housing. A limit assembly is provided at the bottom of the lower connecting rod. A front connecting frame is fixedly connected to the front side of the fan housing.

[0007] As a further description of the above technical solution: The anti-clogging storage mechanism includes a lower connecting piece, the top of which is fixedly connected to the bottom of a rotary motor. A lower rotating shaft is rotatably connected to the bottom of the lower connecting piece. A stirring mechanism is provided on the bottom of the outer wall of the lower rotating shaft. A seed storage tank is provided on the outer wall of the lower rotating shaft. A side connecting rod is fixedly connected to the outer wall of the seed storage tank. An anti-slip sealing assembly is provided on the front top of the seed storage tank. A lower seed outlet is fixedly connected to the bottom of the seed storage tank.

[0008] As a further description of the above technical solution: The air intake assembly includes an upper fixing ring, the bottom of which is fixedly connected to the top of an upper connecting ring, and a plurality of air intake filter plates are fixedly connected to the inner wall of the upper fixing ring.

[0009] As a further description of the above technical solution: The limiting component includes a lower fixing post, the top of which is fixedly connected to the bottom of the lower connecting rod, and a seed limiting ring is fixedly connected to the front side of the lower fixing post.

[0010] As a further description of the above technical solution: The stirring mechanism includes a side stirring rod, the top of which is fixedly connected to the top of the outer wall of the lower rotating shaft, and the bottom of which is fixedly connected to a lower rotating blade.

[0011] As a further description of the above technical solution: The anti-slip sealing assembly includes a sealing cap, the bottom of which is rotatably connected to the top front side of the seed storage tank, and multiple anti-slip edges are fixedly connected to the outer wall of the sealing cap.

[0012] As a further description of the above technical solution: The top of the wind turbine casing is equipped with the main body of the drone, and a front detector is fixedly connected to the bottom front side of the main body of the drone.

[0013] As a further description of the above technical solution: A top connecting frame is fixedly connected to the top of the drone body, and drone fan blades are fixedly connected to the bottom of the top connecting frame.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a small blower is provided at the rear bottom of the device, which, together with the seed placement limiting ring, forms a directional auxiliary structure for seed placement. The small blower can apply a stable directional airflow to the seeds when they are discharged from the placement port, giving the seeds an initial velocity in a preset direction. This initial velocity can counteract the interference of external wind force on the seed's falling trajectory and reduce the deviation of the seeds caused by wind force. The seed placement limiting ring can physically constrain the seed discharge path, preventing the seeds from spreading due to airflow disturbance in the early stage of discharge, further ensuring that the seeds fall according to the preset trajectory, significantly improving sowing efficiency, reducing the probability of sowing failure in windy environments, and ensuring the stability of agricultural sowing operations.

[0015] 2. In this utility model, the seed storage tank of the device is equipped with an anti-clogging structure. The outlet of the seed storage tank is a key channel for seed transportation. When seeds aggregate due to factors such as humidity and particle size differences, blockages can easily form at the outlet, causing seeds to be unable to be transported normally and interrupting the sowing operation. However, the stirring blade driven by the rotary motor continuously stirs the seeds at the outlet of the seed storage tank, breaking up the aggregated seeds and ensuring that the seeds always enter the seed delivery pipeline in a loose state through the outlet, ensuring the continuity of seed transportation. This structure does not require manual intervention to clear blockages, reducing operation interruption time, further improving the overall sowing efficiency, and reducing the risk of operation failures caused by blockages.

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.

[0023] Reference Figures 2-3 An embodiment of this utility model is provided: a drone seeding device, including a fan housing 1, a rotary motor 2 is provided on the front side of the fan housing 1, a seed blowing mechanism 3 is provided on the bottom of the fan housing 1, the seed blowing mechanism 3 is used to blow air on the sown seeds to ensure the seeds land accurately, and an anti-blocking storage mechanism 4 is provided on the bottom of the rotary motor 2, the anti-blocking storage mechanism 4 is used to store the sown seeds and prevent the seed outlet from being blocked. The seed blowing mechanism 3 includes an upper connecting ring 31, the bottom of which is fixedly connected to the top of the fan housing 1. A side heat sink 32 is fixedly connected to the right side of the fan housing 1. A power connection line 33 is fixedly connected to the front side of the fan housing 1. A rotating fan 34 is rotatably connected inside the fan housing 1. An air inlet assembly 35 is provided on the top of the fan housing 1. A lower connecting rod 36 is fixedly connected to the bottom of the fan housing 1. A limit assembly 37 is provided at the bottom of the lower connecting rod 36. A front connecting frame 38 is fixedly connected to the front side of the fan housing 1. Specifically, a drone seeding device includes a fan housing 1, a rotary motor 2, a seed blowing mechanism 3, and an anti-blocking storage mechanism 4. The components work together to achieve the drone seeding function. The fan housing 1 is made of aluminum alloy with a thickness of 2mm, and the small rotary motor 2 has a housing of 1.2mm thick aluminum alloy, a rated voltage of 12V, a rated power of 25W, and a rated speed of 30r / min. As the core component of the drone seeding device to ensure seed sowing accuracy, the seed blowing mechanism 3 includes an upper connecting ring 31 which is fixed to the top of the blower housing 1 at the bottom, thus establishing a stable connection between the seed blowing mechanism 3 and the blower housing 1 and ensuring that the seed blowing mechanism 3 maintains a relatively fixed position during operation. The side heat sink 32 fixedly connected to the right side of the fan housing 1 can conduct the heat generated inside the fan housing 1 during operation to the outside, preventing heat from accumulating inside the fan housing 1, thereby maintaining the normal working environment of the internal components of the fan housing 1; the power connection cable 33 fixedly connected to the front side of the fan housing 1 can provide power input to the components inside the fan housing 1 that require power to drive, ensuring that these components receive a continuous and stable power supply to achieve their preset functions; The rotating fan 34, which is rotatably connected inside the fan housing 1, can rotate after being driven by electricity. During the rotation, it can change the airflow state inside the fan housing 1, generate airflow that meets the requirements of seed blowing, and provide a power basis for blowing the seeds afterward. The air inlet assembly 35 provided on the top of the fan housing 1 allows external air to enter the fan housing 1 in an orderly manner when the rotary fan 34 is working, replenishing the airflow consumed by the rotation of the rotary fan 34, maintaining the stable circulation of airflow inside the fan housing 1, and ensuring that the rotary fan 34 can continuously generate airflow that meets the requirements of the blowing. The lower connecting rod 36, which is fixedly connected to the bottom of the fan housing 1, can serve as a structural component connecting the fan housing 1 and the limiting component 37, stably setting the limiting component 37 in a designated position and providing structural support for the limiting component 37 to function. The front connecting bracket 38, which is fixedly connected to the front side of the blower housing 1, provides an interface for the connection between the seed blowing mechanism 3 and other related components of the drone, so that the seed blowing mechanism 3 can be stably installed on the drone and ensure that the seed blowing mechanism 3 remains stable during the flight of the drone without affecting the normal sowing of seeds.

[0024] Reference Figures 3-5 The anti-clogging storage mechanism 4 includes a lower connecting piece 41, the top of which is fixedly connected to the bottom of the rotary motor 2. The bottom of the lower connecting piece 41 is rotatably connected to a lower rotating shaft 42. A stirring mechanism 43 is provided on the bottom of the outer wall of the lower rotating shaft 42. A seed storage tank 44 is provided on the outer wall of the lower rotating shaft 42. A side connecting rod 45 is fixedly connected to the outer wall of the seed storage tank 44. An anti-slip sealing assembly 46 is provided on the front side of the top of the seed storage tank 44. A lower seed outlet 47 is fixedly connected to the bottom of the seed storage tank 44. Specifically, the anti-blocking storage mechanism 4, as an important part of the drone seeding device for storing seeds and preventing outlet blockage, includes a lower connecting piece 41 which is fixed to the bottom of the rotary motor 2 at the top, thus establishing a stable connection between the anti-blocking storage mechanism 4 and the rotary motor 2, so that the anti-blocking storage mechanism 4 can obtain the corresponding power transmission foundation as the rotary motor 2 operates. The lower rotating shaft 42, which is rotatably connected to the bottom of the lower connecting piece 41, can rotate after obtaining power. Its rotational motion can provide driving force for the stirring mechanism 43 set at the bottom, and at the same time drive the seeds in the seed storage tank 44 to generate a certain movement, so as to prevent the seeds from being left to stand still in the tank for a long time and causing them to accumulate. The stirring mechanism 43, located at the bottom of the outer wall of the lower rotating shaft 42, can stir the seeds at the bottom of the seed storage tank 44 during the rotation of the lower rotating shaft 42, breaking up the clumps formed by the seeds and preventing the seeds from blocking the lower seed outlet 47 due to clumping, ensuring that the seeds can be discharged smoothly from the outlet; the seed storage tank 44, located on the outer wall of the lower rotating shaft 42, is used to hold the seeds to be sown. Its internal space provides a storage place for the seeds, and the tank wall can protect the seeds and prevent external factors from damaging them; The side connecting rod 45, which is fixedly connected to the outer wall of the seed storage tank 44, can be connected to other structural components of the drone to provide additional support for the seed storage tank 44, enhance the stability of the seed storage tank 44 during drone flight and sowing, and prevent it from affecting seed storage and discharge due to shaking. The anti-slip sealing component 46 provided on the front of the top of the seed storage tank 44 can increase the friction between the seal and the tank opening when the top opening of the seed storage tank 44 is closed, preventing the seal from loosening during the movement of the drone and preventing the seeds inside the tank from leaking out from the top. It also makes it easier for the operator to open the seal and add seeds. The seed storage tank 44 is fixedly connected to the bottom of the seed outlet 47, which is the channel for the seeds inside the tank to be discharged. Its structural design works in conjunction with the stirring action of the stirring mechanism 43. Under the premise that the stirring mechanism 43 prevents the seeds from clogging, the seeds can be discharged from the outlet in an orderly and continuous manner, providing a stable output path for subsequent seed sowing.

[0025] Reference Figures 1-2The air inlet assembly 35 includes an upper fixing ring 351, the bottom of which is fixedly connected to the top of an upper connecting ring 31. Multiple air inlet filter sheets 352 are fixedly connected to the inner wall of the upper fixing ring 351. The limiting assembly 37 includes a lower fixing post 371, the top of which is fixedly connected to the bottom of a lower connecting rod 36. A seed limiting ring 372 is fixedly connected to the front side of the lower fixing post 371. The stirring mechanism 43 includes a side stirring rod 431, the top of which is fixedly connected to the outer wall of a lower rotating shaft 42. At the top, a lower rotating blade 432 is fixedly connected to the bottom of the side stirring rod 431. The anti-slip sealing assembly 46 includes a sealing cover 461. The bottom of the sealing cover 461 is rotatably connected to the front of the top of the seed storage tank 44. Multiple anti-slip edges 462 are fixedly connected to the outer wall of the sealing cover 461. A drone body 5 is provided on the top of the fan housing 1. A front detector 6 is fixedly connected to the front of the bottom of the drone body 5. A top connecting frame 7 is fixedly connected to the top of the drone body 5. A drone fan blade 8 is fixedly connected to the bottom of the top connecting frame 7. Specifically, the air inlet assembly 35, as the part in the seed blowing mechanism 3 that ensures stable airflow input, includes an upper fixing ring 351 which is fixed at the bottom and the top of the upper connecting ring 31, to establish a stable connection between the air inlet assembly 35 and other parts of the seed blowing mechanism 3, ensuring that the air inlet assembly 35 remains in a fixed position at the top of the blower housing 1 and does not shift with the airflow. Multiple air inlet filter plates 352 are fixedly connected to the inner wall of the upper fixing ring 351. These filter plates can filter the air entering the fan housing 1, intercepting impurities and particulate matter in the air. This prevents impurities from entering the fan housing 1 with the airflow and adhering to the surface of the rotary fan 34, thus preventing impurities from affecting the normal rotation of the rotary fan 34. At the same time, it prevents impurities from mixing with the seeds and affecting seed quality. The air inlet filter plates 352 are designed to work in accordance with the operating requirements of the rotary fan 34. This ensures that air enters smoothly while improving air quality, providing support for the rotary fan 34 to continuously generate clean airflow. This, in turn, ensures that the blowing effect of the seed blowing mechanism 3 on the seeds is stable and ensures that the seeds land accurately. The limiting component 37, as the part of the seed blowing mechanism 3 that limits the seed sowing path, includes a lower fixing column 371 which is fixed to the bottom of the lower connecting rod 36 through its top, providing a stable mounting base for the limiting component 37. This allows the limiting component 37 to be fixed at a designated position below the blower housing 1, corresponding to the position of the lower seed outlet 47. The seed limiting ring 372, which is fixedly connected to the front of the lower fixing column 371, can constrain the movement trajectory of the seed after it is discharged from the lower seed outlet 47, preventing the seed from deviating excessively under the action of airflow and ensuring that the seed falls within the preset sowing range. The function of the seed limiting ring 372 is coordinated with the airflow generated by the seed blowing mechanism 3. The airflow provides sowing power for the seed, while the seed limiting ring 372 regulates the direction of seed movement. The combination of the two improves the uniformity and accuracy of seed sowing, further ensuring the precise landing point of the seed. The stirring mechanism 43 is the core part of the anti-clogging storage mechanism 4 to prevent seed blockage. The side stirring rod 431 is fixed to the top of the outer wall of the lower rotating shaft 42 and moves synchronously with the rotation of the lower rotating shaft 42. During the rotation, the side stirring rod 431 can stir the seeds in the upper middle part of the seed storage tank 44, break the static state of the seeds in the tank, and prevent the seeds from accumulating at the bottom of the tank for a long time due to gravity and forming a dense clump. The lower rotating blade 432, which is fixedly connected to the bottom of the side stirring rod 431, can more finely stir the seeds at the bottom of the seed storage tank 44 when rotating with the side stirring rod 431. It focuses on the area at the bottom of the tank that is prone to blockage, breaking up the seeds that have begun to clump together, and at the same time pushing the seeds to move downward to the lower seed outlet 47. The stirring action of the lower rotating blade 432 is directly related to the seed discharge requirements of the lower seed outlet 47. Through continuous stirring, it ensures that the seeds can enter the lower seed outlet 47 in a loose state, preventing the seeds from forming a blockage at the outlet, ensuring the continuity of seed discharge, and providing a stable seed supply for the subsequent sowing process. The anti-slip sealing assembly 46, as the part of the anti-blocking storage mechanism 4 that ensures the airtightness of seed storage, includes a sealing cap 461 that is rotatably connected to the top front of the seed storage tank 44 via its bottom. This allows for the opening and closing of the top opening of the seed storage tank 44. When the operator opens the sealing cap 461, seeds can be added into the tank, and when closed, the tank opening is sealed to prevent seeds from leaking out from the top during drone flight. Multiple anti-slip edges 462 are fixedly connected to the outer wall of the sealing cap 461, increasing the friction between the operator's hand and the sealing cap 461 when the operator opens the sealing cap 461, making it easier for the operator to apply force and preventing hand slippage that would cause inconvenience. The anti-slip edges 462 are designed to match the usage requirements of the sealing cap 461, improving the ease of operation of the sealing cap 461, while ensuring that the sealing cap 461 fits tightly against the tank opening after being closed, enhancing the airtightness of the seed storage tank 44 and further ensuring the safety of the seeds during storage.

[0026] Working principle: This drone seeding device achieves efficient and precise seeding through the coordinated action of its components. Its core components include a fan housing 1, a rotary motor 2, a seed blowing mechanism 3, and an anti-clogging storage mechanism 4. These components form a complete working system through specific connections. The seed blowing mechanism 3 is responsible for assisting the sowing of seeds with airflow, while the anti-clogging storage mechanism 4 is responsible for storing seeds and preventing outlet blockage. With the power support of the rotary motor 2 and the structural support of the fan housing 1, the two work together to complete the core function of seeding. The upper connecting ring 31 is fixedly connected to the top of the fan housing 1 through the bottom, providing a top structural fixed support for the seed blowing mechanism 3 and ensuring the stability of the entire mechanism during operation; a side heat sink 32 is fixedly connected to the right side of the fan housing 1. The side heat sink 32 conducts heat with the fan housing 1 to dissipate the heat generated inside the fan housing 1 by the operation of the rotating fan 34, avoiding heat accumulation that affects the operating efficiency of the components, and thus ensuring the continuous and stable operation of the seed blowing mechanism 3; A power connection cable 33 is fixedly connected to the front of the fan housing 1. The power connection cable 33 is used to connect to an external power source to provide power support for the operation of the rotary fan 34, ensuring that the seed blowing mechanism 3 has a continuous power source for operation. The rotary fan 34 is rotatably connected inside the fan housing 1. The rotary fan 34 rotates at high speed under the power provided by the power connection cable 33, generating a directional airflow. This airflow serves as the power basis for seed blowing, providing airflow guarantee for subsequent precise seed sowing. An air intake component 35 is provided on the top of the fan housing 1. When the rotary fan 34 is running, the air intake component 35 introduces external air into the fan housing 1 through its internal ventilation structure, supplementing the air volume required for the operation of the rotary fan 34, ensuring that the rotary fan 34 can continuously generate a stable airflow, and avoiding air shortages. The reduced flow intensity affects the seed blowing effect. A lower connecting rod 36 is fixedly connected to the bottom of the fan housing 1. A limit component 37 is provided at the bottom of the lower connecting rod 36. The lower connecting rod 36 provides fixed support for the limit component 37. The limit component 37, through its own limit structure, provides initial guidance and position restriction for the seeds falling from the anti-blocking storage mechanism 4, so that the seeds can accurately enter the airflow area generated by the rotating fan 34 and avoid the seeds deviating from the airflow range and thus not being effectively blown. A front connecting frame 38 is fixedly connected to the front side of the fan housing 1. The front connecting frame 38 is used to connect and fix the seed blowing mechanism 3 to other structures of the drone, ensuring that the seed blowing mechanism 3 maintains a stable position during the flight of the drone and avoiding the seed blowing mechanism 3 from shifting due to the shaking of the drone, which would affect the seed sowing accuracy. The top of the lower connecting piece 41 is fixedly connected to the bottom of the rotary motor 2. The power generated when the rotary motor 2 is running is transmitted to other components of the anti-blocking storage mechanism 4 through the lower connecting piece 41, providing a power basis for the realization of the anti-blocking function. The bottom of the lower connecting piece 41 is rotatably connected to the lower rotating shaft 42. The lower rotating shaft 42 rotates under the power transmitted by the rotary motor 2 through the lower connecting piece 41, and transmits the rotational power to the stirring mechanism 43. The stirring mechanism 43 is provided at the bottom of the outer wall of the lower rotating shaft 42. The stirring mechanism 43 rotates synchronously with the rotation of the lower rotating shaft 42, stirring the stored seeds inside the seed storage tank 44, breaking up the clumps formed between the seeds, and pushing the seeds to move towards the lower seed outlet 47 at the bottom of the seed storage tank 44, avoiding the accumulation of seeds at the outlet, thereby preventing the seed outlet from being blocked. A seed storage tank 44 is installed on the outer wall of the lower rotating shaft 42. The seed storage tank 44, through its cooperation with the lower rotating shaft 42, forms a closed seed storage space to hold seeds to be sown. Its internal size is designed according to sowing needs to ensure sufficient seed storage and reduce the frequency of seed replenishment during sowing. A side connecting rod 45 is fixedly connected to the outer wall of the seed storage tank 44. The side connecting rod 45 connects the seed storage tank 44 to other support structures of the drone, further enhancing the stability of the anti-blocking storage mechanism 4 during drone flight and preventing the seed storage tank 44 from shaking due to drone turbulence, which would affect seed descent and the anti-blocking effect. The top of the seed storage tank 44... A non-slip sealing component 46 is provided on the front side. The non-slip sealing component 46, through its non-slip structure and sealing design, seals the mouth of the seed storage tank 44 after the seeds are loaded into it, preventing the seeds from leaking out of the mouth during the flight of the drone. At the same time, the non-slip structure ensures that the sealing component is not easy to loosen in the vibration environment, ensuring the reliability of the seal. The bottom of the seed storage tank 44 is fixedly connected to a lower seed outlet 47. The lower seed outlet 47 serves as a channel for the seeds to be output from the storage tank. Its diameter is designed according to the size of the seed particles to ensure that the seeds can fall smoothly. At the same time, with the stirring and pushing action of the stirring mechanism 43, the seeds are further prevented from clogging at the outlet, providing a stable seed source for the precise blowing of the subsequent seed blowing mechanism 3. Open the seed storage tank 44 by using the anti-slip sealing assembly 46 on the front top of the seed storage tank 44, and load the seeds to be sown into the seed storage tank 44. After loading, close the anti-slip sealing assembly 46 to prevent seeds from leaking out, while the anti-slip structure ensures that the sealing assembly remains stable during the drone's flight. Then, connect an external power source through the power connection cable 33 to provide power to the entire device. At this time, the rotary motor 2 starts to run, and the power it generates is transmitted to the lower rotating shaft 42 through the lower connecting piece 41. This causes the lower rotating shaft 42 to drive the bottom stirring mechanism 43 to rotate inside the seed storage tank 44. During the rotation, the stirring mechanism 43 stirs the seeds, breaks up seed clumps, and pushes the seeds toward the lower seed outlet 47 at the bottom of the seed storage tank 44 to prevent seeds from accumulating and clogging at the outlet, ensuring that the seeds can fall continuously and stably from the lower seed outlet 47. The power supply provides power to the rotating fan 34 inside the fan housing 1, causing the rotating fan 34 to rotate at high speed. During operation, the rotating fan 34 draws in external air through the air intake assembly 35 at the top of the fan housing 1. After being accelerated by the rotating fan 34, the air forms a directional airflow that flows downward to the bottom area of ​​the fan housing 1. When the seeds falling from the seed outlet 47 enter the bottom of the fan housing 1, they first pass through the limiting assembly 37 at the bottom of the lower connecting rod 36. The limiting assembly 37 guides and restricts the position of the seeds, ensuring that the seeds accurately enter the area affected by the airflow generated by the rotating fan 34. The airflow generates a horizontal thrust on the seeds, adjusting their falling trajectory so that the seeds can accurately land at the target sowing position. This avoids the problem of scattered seed landing points caused by free fall. Throughout the operation, the side heat sink 32 on the right side of the fan housing 1 continuously dissipates the heat generated by the rotating fan 34, preventing the internal temperature of the fan housing 1 from being too high and affecting the operating efficiency of the rotating fan 34, thus ensuring stable airflow intensity. At the same time, the front connecting frame 38 and the side connecting rod 45 respectively fix the seed blowing mechanism 3 and the anti-clogging storage mechanism 4 to the drone, ensuring the stability of the entire device during the drone's flight and preventing shaking from affecting the seed falling path and airflow effect. Through the coordinated operation of the above components, the complete functions of seed storage, anti-clogging delivery, and precise sowing are realized, effectively improving sowing efficiency and accuracy.
