Description

Technical Field

[0001] This invention belongs to the field of seeding device technology, specifically relating to a drone seeding device. Background Technology

[0002] In the field of drone seeding, traditional drone seeding devices typically have fixed-volume hoppers, which cannot flexibly adjust the internal space according to actual seeding needs. When large-area seeding operations are required, the limited amount of seeds that a fixed-volume hopper can hold forces the drone to frequently return to the ground to resupply seeds, wasting a lot of time and severely reducing the overall efficiency of the seeding operation. On the other hand, in scenarios involving small-area seeding or when the drone's payload capacity is limited, a fixed-volume hopper filled with seeds would overload the drone, affecting flight stability, and would also result in seed surplus after the operation, leading to seed waste.

[0003] In view of the above problems, this application proposes a drone seeding device to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a drone seeding device that can drive the first and second hoppers to move vertically by rotating a threaded rod with opposite external threads, in conjunction with corresponding upper and lower ear plates. This allows for flexible adjustment of the hopper volume.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A drone seeding device includes a first hopper and a connecting rod. The connecting rod is fixed to the upper end of the first hopper. A second hopper is nested inside the first hopper. First ear plates are fixed to both sides of the first hopper, and second ear plates are fixed to both sides of the second hopper, with the second ear plates located directly below the first ear plates. A threaded rod is threadedly connected between the first and second ear plates. The threaded rod has two external threads on its outer side, with the two external threads rotating in opposite directions. The lower end of the threaded rod extends to the lower end of the second ear plate, and a knob is fixed to the lower end of the threaded rod. The device also includes a seeding mechanism, which is assembled at the lower end of the second hopper.

[0007] In a preferred embodiment, the outer side of the knob is provided with anti-slip texture, and the anti-slip texture is made of rubber.

[0008] In a preferred embodiment, the upper end of the first hopper is provided with inlets on both sides, and a fixing rod is fixed inside each of the two inlets, and a baffle is fixed outside each of the two fixing rods.

[0009] In a preferred embodiment, limit grooves are provided at both ends of the outer side of the second hopper, and limit plates are fixed at both ends of the inner side of the first hopper, and the limit grooves and limit plates are adapted to each other.

[0010] In a preferred embodiment, the seeding mechanism includes a base plate, a motor, a rotating rod, two discharge plates, and two seeding rollers. The base plate is fixed to the lower end of the second hopper, the motor is fixed to one side of the base plate, the rotating rod is fixed to the output end of the motor, the two discharge plates are fixed to both sides inside the base plate, and the two seeding rollers are rotatably connected to the inside of the two discharge plates.

[0011] In a preferred embodiment, multiple seeding grooves are provided on the outer sides of both seeding rollers, and the multiple seeding grooves are arranged in a ring.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model uses a threaded rod with oppositely oriented external threads, in conjunction with corresponding first and second lugs. By rotating the lower knob, the first and second hoppers can be driven to move vertically, achieving flexible adjustment of the hopper volume. When the volume is expanded, it can hold more seeds, reducing the number of times the drone needs to resupply, and significantly improving the efficiency of sowing operations. When the volume is reduced, the amount of seeds carried can be controlled, reducing the drone load, avoiding seed waste, and effectively balancing operational needs and equipment load.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0024] Please see the appendix Figures 1 to 3 As shown, this utility model provides a drone seeding device, including a first hopper 10 and a connecting rod 11. The connecting rod 11 is fixed to the upper end of the first hopper 10. A second hopper 12 is sleeved inside the first hopper 10. First ear plates 13 are fixed on both sides of the first hopper 10. Second ear plates 14 are fixed on both sides of the second hopper 12, and the second ear plates 14 are located directly below the first ear plates 13. A threaded rod 15 is threadedly connected between the first ear plates 13 and the second ear plates 14. Two external threads are provided on the outer side of the threaded rod 15, and the two external threads are turned in opposite directions. The lower end of the threaded rod 15 extends to the lower end of the second ear plate 14. A knob 16 is fixed to the lower end of the threaded rod 15. The device also includes a seeding mechanism 30, which is assembled at the lower end of the second hopper 12.

[0025] In this embodiment, when it is necessary to change the hopper volume, by rotating the knob 16 at the lower end of the threaded rod 15, the two oppositely spiraling external threads on the outer side of the threaded rod 15 drive the first ear plate 13 fixed on both sides of the first hopper 10 and the second ear plate 14 fixed on both sides of the second hopper 12 (the second ear plate 14 is located directly below the first ear plate 13) to move closer or further apart. This allows the second hopper 12, which is fitted inside the first hopper 10, to move vertically. By utilizing the oppositely spiraling external threads of the threaded rod 15 and the cooperation of the two sets of first ear plates 13 and second ear plates 14, the position of the second hopper 12 can be precisely adjusted, expanding the internal volume of the overall hopper, thereby accommodating more seeds, reducing the number of times the drone needs to resupply seeds, and improving operational efficiency. When it is necessary to control the amount of seeds carried to reduce the drone load, the knob 16 is rotated in the opposite direction to reduce the distance between the first ear plate 13 and the second ear plate 14, causing the second hopper 12 to shrink into the first hopper 10, reducing the hopper volume, and avoiding waste due to seed surplus. After the hopper volume is adjusted, the entire device can be connected and fixed to the drone by means of the connecting rod 11 fixed at the upper end of the first hopper 10.

[0026] In a preferred embodiment, please refer to Figure 1 The outer side of knob 16 has anti-slip texture, which is made of rubber.

[0027] In this embodiment, the outer side of the knob 16 is specially provided with anti-slip texture, and the anti-slip texture is made of rubber material. The rubber material itself has a good coefficient of friction. Combined with the anti-slip texture structure on the outer side, it can increase the friction between the user's hand and the knob 16, making it easier for the user to apply force when turning the knob 16.

[0028] Secondly, please refer to it again. Figure 1 and Figure 2 The first hopper 10 has inlet ports 20 on both sides of its upper end. The inside of each inlet port 20 is fixed with a fixing rod 21, and the outside of each fixing rod 21 is fixed with a baffle 22.

[0029] In this embodiment, the two feed inlets 20 on both sides of the upper end of the first silo 10 are designed to enable simultaneous feeding from multiple directions, thereby improving the efficiency of material conveying to the first silo 10 and reducing the feeding congestion that may occur at a single feed inlet 20.

[0030] Secondly, please refer to the following as well. Figure 3 Limiting grooves 25 are provided at both ends of the outer side of the second hopper 12, and limiting plates 26 are fixed at both ends of the inner side of the first hopper 10, and the limiting grooves 25 and the limiting plates 26 are compatible.

[0031] In this embodiment, limit grooves 25 are provided at both ends of the outer side of the second hopper 12, and limit plates 26 are fixed at both ends of the inner side of the first hopper 10, and the limit grooves 25 and the limit plates 26 are compatible. When the screw rod 15 is driven by rotating the knob 16, the first ear plates 13 on both sides of the first hopper 10 and the second ear plates 14 on both sides of the second hopper 12 are brought closer or further away, so that the second hopper 12, which is fitted inside the first hopper 10, moves vertically, the limit grooves 25 at both ends of the outer side of the second hopper 12 will cooperate with the limit plates 26 at both ends of the inner side of the first hopper 10 to restrict the movement trajectory of the second hopper 12, prevent the second hopper 12 from deviating or shaking in the horizontal direction during vertical movement, and ensure that the second hopper 12 always moves stably in the preset direction.

[0032] To further understand and explain, Figures 2 to 4 For example, the seeding mechanism 30 includes a base plate 31, a motor 32, a rotating rod 33, two discharge plates 34, and two seeding rollers 35. The base plate 31 is fixed to the lower end of the second hopper 12, the motor 32 is fixed to one side of the base plate 31, the rotating rod 33 is fixed to the output end of the motor 32, the two discharge plates 34 are fixed to both sides inside the base plate 31, and the two seeding rollers 35 are rotatably connected to the inside of the two discharge plates 34. Multiple seeding grooves 36 are provided on the outer sides of each of the two seeding rollers 35, and the multiple seeding grooves 36 are arranged in a ring.

[0033] In this embodiment, the seeding mechanism 30 includes a base plate 31, a motor 32, a rotating rod 33, two discharge plates 34, and two seeding rollers 35. The base plate 31 is fixed to the lower end of the second hopper 12, providing mounting support for each component. The motor 32 is fixed to one side of the base plate 31, and the rotating rod 33 is fixed to its output end. The two discharge plates 34 are fixed to the inside of the base plate 31 on both sides. The two seeding rollers 35 are rotatably connected to the inside of the two discharge plates 34, and multiple annularly arranged seeding grooves 36 are opened on the outer side of each of the two seeding rollers 35. When the motor 32 is started, the motor 32 drives the two seeding rollers 35 to rotate synchronously through the rotating rod 33. After the seeds in the second hopper 12 fall into the inside of the base plate 31, they enter the multiple seeding grooves 36 on the outer side of the two seeding rollers 35. As the seeding rollers 35 rotate, the multiple seeding grooves 36 carry the seeds to the discharge plate 34, where the seeds are released from the seeding grooves 36 and sown through the discharge plate 34. It should be noted that the motor 32 is electrically connected to the UAV power module via wires. A support plate is fixed to one side of the base plate 31, which is used to support the motor 32. Inclined surfaces are provided on both sides inside the base plate 31.

[0034] The working principle of this utility is as follows:

[0035] First, the entire drone seeding device is connected and fixed to the drone using the connecting rod 11 fixed to the upper end of the first hopper 10. Simultaneously, seeds are added to the device through the two feed inlets 20 on both sides of the upper end of the first hopper 10. When the hopper volume needs to be adjusted according to operational requirements, the user rotates the knob 16 at the lower end of the threaded rod 15 (the anti-slip texture of the rubber material on the outside of the knob 16 increases hand friction for easier application of force). Utilizing the two oppositely oriented external threads on the outside of the threaded rod 15, the first ear plates 13 on both sides of the first hopper 10 and the second ear plates 14 on both sides of the second hopper 12 (located directly below the first ear plates 13) move closer or further apart, thereby causing the second hopper 12, which is fitted inside the first hopper 10, to move vertically. During this process, the limiting grooves 25 at both ends of the outer side of the second hopper 12 and the two internal limiting grooves 25 of the first hopper 10... The limiting plates 26 at the ends are mutually adapted to restrict the movement trajectory of the second hopper 12, prevent it from deviating horizontally, and ensure accurate adjustment of the hopper volume. When sowing is carried out, the motor 32 (fixed on the support plate on one side of the base plate 31) which is electrically connected to the power module of the UAV starts. The rotating rod 33 at the output end of the motor 32 drives the two sowing rollers 35 (rotatably connected between the two discharge plates 34 on both sides inside the base plate 31) to rotate synchronously. The seeds in the second hopper 12 fall into the interior of the base plate 31 (the inclined surface inside the base plate 31 assists the flow of the seeds) and enter the multiple annularly arranged sowing troughs 36 outside the sowing device 35 of the two sowing rollers. As the sowing rollers 35 rotate, the sowing troughs 36 carry the seeds to the discharge plate 34. The seeds leave the sowing troughs 36 and are sown through the discharge plate 34, realizing efficient and uniform sowing driven by the UAV.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
