Description

Technical Field

[0001] This invention relates to the field of agricultural production technology, specifically to a drone-based Trichogramma wasp egg ball dispenser. Background Technology

[0002] Trichogramma wasps are the core natural enemies of biological control of agricultural and forestry pests. By laying their eggs inside the eggs of pests to complete their development and kill the pests, they can effectively control the population of pests before the larvae cause damage. This is a widely used biological control method. The precise placement of their egg balls directly determines the control effect. At present, Trichogramma wasp egg balls are mostly sown manually, which results in low overall operational efficiency.

[0003] To overcome the above-mentioned defects, prior art one (Chinese patent CN220662845U, published on March 26, 2024) describes a Trichogramma wasp delivery drone, including a flying robot, a delivery bucket, a bee inlet, a connecting part, a connecting structure, a diversion mechanism, and a bee outlet. In this drone, the delivery bucket and the flying robot are designed with a detachable structure, facilitating quick assembly and disassembly of the delivery bucket and the flying robot, thus making it easier for workers to clean the delivery bucket. The diversion mechanism design allows bee eggs to grow and develop autonomously within the delivery bucket to the delivery standard, and then be delivered through the bee outlet, effectively improving the survival rate of successfully parasitized bee eggs. Prior art two (Chinese patent CN218055624U, published on December 16, 2022) describes a... This drone-based Trichogramma wasp egg ball delivery device addresses the problems of manual Trichogramma wasp egg ball delivery in existing technologies, which requires advance planning of the delivery location and is difficult and inefficient due to space limitations. The proposed solution includes a delivery tray, a delivery channel, a limiting plate, a rotating shaft, and a motor. The delivery tray holds the Trichogramma wasp eggs and has a circular hole through which the eggs pass. The delivery channel is located below the circular hole, and the limiting plate is located below the delivery channel. Both the delivery tray and the delivery channel are connected to the rotating shaft and rotate with it. The end of the rotating shaft furthest from the delivery tray is connected to the motor, which controls the rotational speed of the shaft. The purpose of this device is to enable drone-based delivery of Trichogramma wasp eggs, significantly saving manpower and improving efficiency.

[0004] While existing technologies have improved the efficiency of Trichogramma egg ball delivery by relying on drones, the diversion mechanism can only enable the eggs to develop autonomously and bee emergence, but cannot precisely control the egg ball delivery spacing and the amount delivered at one time. Furthermore, the direct-fall feeding design lacks an orderly egg ball transport structure, which makes the eggs prone to accumulating and getting stuck at the storage bin and the feeding port, thus causing feeding interruptions.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing drone-based Trichogramma egg ball dispenser. Therefore, we proposed a drone-based Trichogramma egg ball dispenser that can effectively solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a drone-based Trichogramma wasp egg ball dispenser to address the issues raised in the background section. While current drone-based systems have improved the efficiency of Trichogramma wasp egg ball dispensing, their diversion mechanisms only enable autonomous egg development and bee emergence, failing to precisely control the egg ball dispensing spacing and single-dispensing quantity. Furthermore, their drop-type design lacks an orderly egg ball transport structure, leading to egg ball accumulation and jamming at the storage bin and dispensing port, thus causing dispensing interruptions.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a drone-based Trichogramma wasp egg ball dispenser, comprising a drone body, a storage box under the drone body, a dispensing box connected to the storage box via a conveying cylinder, a storage hopper inside the storage box, a conveying assembly inside the storage hopper, a drive motor installed inside the storage hopper, a rotating shaft connected to the output end of the drive motor, the rotating shaft extending through into the conveying cylinder, a rotating cylinder connected to a support base, a threaded plate on the support base, the threaded plate being axially connected to the outside of the rotating shaft, blades on the rotating cylinder, the blades being equiangularly arranged and located inside the dispensing box, a dispensing groove on the side wall of the dispensing box, and a monitoring component below the dispensing box.

[0008] Preferably, a support base is provided at the connection between the conveying cylinder and the feeding box, and a feeding hole is provided on the support base. The feeding hole is located directly below the end of the thread extension of the threaded plate, and a partition is installed on the support base. The partition is located on the side of the feeding hole.

[0009] Preferably, the rotating cylinder is provided with an adjustment component, which includes a shelf installed inside the rotating cylinder, a dual-axis motor installed on the shelf, and a drive gear connected to the first output end of the dual-axis motor.

[0010] Preferably, the driving gear is meshed with a driven gear on its side end, a rotating rod is connected through the driven gear, a bracket is installed on the outside of the rotating rod, the rotating rod is connected through the inside of the blade, and a rotating groove for the blade to rotate is opened on the outside of the rotating cylinder.

[0011] Preferably, the inner wall of the dispensing box has a cavity, and the outer side of the dispensing box has a heat dissipation hole, which is connected to the cavity.

[0012] Preferably, a sleeve is installed under the shelf, a moving rod is connected inside the sleeve by a spring, a lifting plate is connected below the moving rod, and an electromagnetic structure is installed inside the sleeve and at the end of the moving rod.

[0013] Preferably, the second output end of the dual-axis motor is connected to a first rotating rod, a first locking block is installed under the first rotating rod, and a first locking groove adapted to the first locking block is provided on the lifting plate.

[0014] Preferably, a second locking block is connected to the first locking slot via a second rotating rod, and the second rotating rod extends through the lifting plate and the rotating cylinder into the cavity.

[0015] Preferably, a rotating plate is provided inside the cavity, a baffle is provided at the end of the rotating plate, the baffle is located at the side of the heat dissipation hole, and a second slot adapted to the second card block is provided inside the rotating plate.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: This drone-based Trichogramma wasp egg ball dispenser uses threaded blades to gradually transport the Trichogramma wasp eggs from the storage hopper downwards, preventing egg ball accumulation and jamming. The equally angled blades ensure uniform egg ball distribution, thereby improving the coverage and effectiveness of biological control and avoiding the problem of overly dense or sparse localized distribution. The specific details are as follows: (1) The drone moves above the desired delivery location. Due to gravity, the Trichogramma eggs in the storage bin are gradually transported downwards through the spiral plate, which facilitates the stable transmission of the Trichogramma eggs and avoids the accumulation and jamming of the eggs.

[0017] (2) The feeding hole of the support is precisely aligned with the end of the threaded plate extension to ensure that all the conveyed balls can fall into the feeding box, avoiding waste of balls. The partition on the support can effectively prevent the balls from overflowing from the side of the feeding hole, playing a good limiting role, ensuring that the balls are conveyed in an orderly manner, and eliminating the problem of side leakage.

[0018] (3) The blades on the rotating cylinder are set at equal angles and rotate synchronously with the rotating shaft. They can push the egg balls falling from the feeding hole to the delivery slot evenly, so as to achieve uniform delivery of egg balls and avoid the problem of local delivery being too dense or too sparse. The monitoring device under the delivery box can provide real-time feedback on the delivery screen, so that the control end can adjust the delivery deviation in time to ensure that the egg balls are accurately delivered to the target area and improve the coverage and effect of biological control.

[0019] (4) The monitoring device below the delivery box monitors the delivery screen in real time and feeds the data back to the control terminal. It can quickly determine the delivery situation in the current environment and adjust the blade deflection angle through the control terminal to prevent the overall delivery effect from being poor due to the large wind speed in the environment.

[0020] (5) The cavity inside the feeding box is connected to the heat dissipation holes on the outside, which can effectively dissipate the heat generated by the operation of the equipment, maintain a suitable temperature inside the feeding box, prevent the Trichogramma egg balls from being deactivated by high temperature, and flexibly adjust the opening range of the heat dissipation holes to achieve precise heat dissipation according to the operating temperature of the equipment and the ambient temperature.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: In this example, the equiangularly arranged leaves 12 can achieve uniform delivery of the egg balls, thereby ensuring even distribution of Trichogramma wasp eggs, improving the coverage and effectiveness of biological control, and avoiding the problem of excessively dense or sparse local distribution. Figures 1-5The technical solution shown includes a drone body 1, a storage box 2 located below the drone body 1, and a delivery box 4 connected to the storage box 2 via a conveyor cylinder 3. The storage box 2 has a storage hopper inside, and a conveying assembly is installed inside the storage hopper. The conveying assembly includes a drive motor 5 installed inside the storage hopper, with a rotating shaft 6 connected to the output end of the drive motor 5. The rotating shaft 6 extends through the conveyor cylinder 3 and passes through a support base 8, connecting to a rotating cylinder 11. A threaded plate 7 is mounted on the support base 8, and the threaded plate 7 is axially connected to the outside of the rotating shaft 6. Blades 12 are mounted on the rotating cylinder 11, arranged at equal angles, and located inside the delivery box 4. The side wall of the delivery box 4 has a delivery slot 13. A monitoring device is installed below the delivery box 4. A support base 8 is installed at the connection between the conveyor cylinder 3 and the delivery box 4. A discharge hole 9 is opened on the support base 8. The discharge hole 9 is located directly below the end of the thread extension of the threaded plate 7. A partition 10 is installed on the support base 8. The partition 10 is located on the side of the discharge hole 9. The drone body 1 provides the flight carrier for the entire device. The storage box 2 below it is used to store Trichogramma wasp eggs. The storage hopper inside the storage box 2 provides storage space for the eggs. When the slot plug inside the delivery slot 13 of the delivery box 4 is opened, the drone body 1 moves above the desired delivery position. Due to gravity, the storage hopper... The Trichogramma wasp eggs are gradually conveyed downwards via the threaded plate 7 until they reach the inside of the conveyor cylinder 3. This ensures a smooth and orderly conveying of the eggs, preventing them from accumulating or getting stuck. A support base 8 is provided at the connection between the conveyor cylinder 3 and the delivery box 4. The discharge hole 9 on the support base 8 is located directly below the end of the thread extension of the threaded plate 7. After being conveyed by the threaded plate 7, the eggs fall into the delivery box 4 through the discharge hole 9. The partition plate 10 on the support base 8 prevents the eggs from overflowing from the side of the discharge hole 9, thus acting as a limit and ensuring that the Trichogramma wasp eggs are conveyed sequentially for easy subsequent delivery. The output end of the drive motor 5 drives the rotating shaft 6 to rotate. The rotating shaft 6 passes through the support base 8, and its lower end is connected to... The rotating cylinder 11 rotates synchronously with the rotating shaft 6. The blades 12, which are set at equal angles on the rotating cylinder 11, are located inside the delivery box 4. When the blades 12 rotate, they push the egg balls falling from the feeding hole 9 to the delivery groove 13 on the side wall of the delivery box 4. Finally, the eggs are delivered to the designated area through the delivery groove 13. The blades 12, which are set at equal angles, can push the egg balls evenly, thereby achieving the uniform delivery of Trichogramma wasp eggs, improving the coverage and effect of biological control, and avoiding the problem of local delivery being too dense or too sparse. The monitoring device below the delivery box 4 monitors the delivery screen in real time and feeds the data back to the control terminal, which facilitates understanding of the delivery situation and improves the convenience and intelligence of equipment operation.

[0025] Example 2: In this example, the first output end of the dual-axis motor 14 is started, driving the rotating rod 18 to rotate through the driving gear 15 and the driven gear 16, thereby causing the blade 12 to deflect within the rotating groove 19, realizing the adjustment of the blade 12 angle, ensuring uniform and accurate egg ball placement, as detailed below. Figures 4-8As shown, the following is disclosed: An adjustment assembly is provided inside the rotating cylinder 11. The adjustment assembly includes a shelf 20 installed inside the rotating cylinder 11. A dual-axis motor 14 is mounted on the shelf 20. The first output end of the dual-axis motor 14 is connected to a drive gear 15. A driven gear 16 is meshed with the side end of the drive gear 15. A rotating rod 18 is internally connected to the driven gear 16. A bracket 17 is installed on the outside of the rotating rod 18. The rotating rod 18 is internally connected to the blade 12. A rotating groove 19 for the rotation of the blade 12 is opened on the outside of the rotating cylinder 11. The shelf 20 in the adjustment assembly is used to mount the dual-axis motor 14. The dual-axis motor 14 achieves electrical energy conduction through sliding contact between a rotating slip ring and a fixed brush connected to an external power source. The dual-axis motor 14 provides power to the adjustment structure, and its first output end is connected to the drive gear. 15. The driving gear 15 is linked with the driven gear 16 meshing at the side end. The rotating rod 18 passing through the inside of the driven gear 16 rotates synchronously under the support of the bracket 17. The rotating rod 18 is connected inside the blade 12. The rotating cylinder 11 has a rotating groove 19 on the outside for the blade 12 to rotate. Therefore, the monitoring device below the delivery box 4 monitors the delivery screen in real time and feeds the data back to the control terminal. It can quickly judge the delivery situation in the current environment. The deflection angle of the blade 12 can be adjusted by the control terminal to prevent the problem of poor overall delivery effect due to high ambient wind speed. The first output end of the dual-axis motor 14 is started. The driving gear 15 and the driven gear 16 drive the rotating rod 18 to rotate, which in turn drives the blade 12 to deflect in the rotating groove 19, realizing the adjustment of the blade 12 angle, ensuring that the egg ball delivery is uniform and accurate. The overall structure is simple and easy to maintain.

[0026] Example 3: In this example, the rotating plate 33 drives the baffle 35 to rotate, thereby adjusting the opening range of the heat dissipation hole 22 to prevent the Trichogramma egg cells from becoming inactive due to excessive temperature. Specifically, as shown below... Figures 6-13As shown, the following is disclosed: a cavity 21 is formed in the inner wall of the dispensing box 4, and a heat dissipation hole 22 is formed in the outer side of the dispensing box 4, which is connected to the cavity 21. A sleeve 23 is installed under the placement plate 20. A moving rod 25 is connected to the inside of the sleeve 23 through a spring 24. A lifting plate 27 is connected to the bottom of the moving rod 25. An electromagnetic structure 26 is installed inside the sleeve 23 and at the end of the moving rod 25. A first rotating rod 28 is connected to the second output end of the dual-axis motor 14. A first locking block 29 is installed under the first rotating rod 28. A first locking groove 30 adapted to the first locking block 29 is provided on the lifting plate 27. A second locking block 32 is connected to the first locking groove 30 through a second rotating rod 31. The second rotating rod 31 extends through the lifting plate 27 and the rotating cylinder 11 into the cavity 21. A rotating plate 33 is installed inside the cavity 21, and a baffle 35 is installed at the end of the rotating plate 33. The baffle 35 is located on the side of the heat dissipation hole 22. A second slot 34 adapted to the second locking block 32 is provided inside the rotating plate 33. The cavity 21 is opened in the inner wall of the feeding box 4. The heat dissipation hole 22 on the outside of the feeding box 4 is connected to the cavity 21 for heat dissipation of the equipment to prevent the Trichogramma egg balls from being deactivated due to excessive temperature. A separate heat dissipation structure can be set inside the storage box 2, such as installing a cooling fan on the top of the storage box 2 to transfer heat between the storage box 2 and the inside of the conveying cylinder 3. This structure is existing technology and will not be described in detail. A spring 24 is installed inside the sleeve 23 installed below the placement plate 20. The spring 24 is connected to the moving rod 2. 5. The lower end of the moving rod 25 is connected to the lifting plate 27. An electromagnetic structure 26 is installed inside the sleeve 23 and at the end of the moving rod 25. The processor is directly connected to the electromagnetic structure 26. By controlling the electromagnetic structure 26, the two magnetic blocks are attracted or repelled, thereby controlling the moving rod 25 to drive the lifting plate 27 to move up and down. When the environment does not require the activation of the heat dissipation-related structure, the two magnetic blocks of the electromagnetic structure 26 are controlled to repel each other. At this time, the first rotating rod 28 and the second rotating rod 31 are not connected, and the dual-axis motor 14 can only drive the blade 12 to perform angle adjustment. When the heat dissipation structure needs to be activated, the processor controls the electromagnetic structure 26 to work, so that the two magnetic blocks attract each other. Under the action of the spring 24 and the electromagnetic force, the moving rod 25 drives the lifting plate 27 to move upward. The lifting plate 27 drives the second rotating rod 28 to move upward. The rod 31 and the second locking block 32 move upward, causing the second locking block 32 to engage in the second locking slot 34. At this time, the second output end of the dual-axis motor 14 starts, driving the first rotating rod 28 and the first locking block 29 to rotate. Since the first locking block 29 is engaged in the first locking slot 30, the lifting plate 27, the second rotating rod 31, and the second locking block 32 rotate synchronously, thereby driving the rotating plate 33 to rotate. The rotating plate 33 drives the baffle 35 to rotate, thereby adjusting the opening range of the heat dissipation hole 22. Heat dissipation is achieved through the cooperation of the cavity 21 and the heat dissipation hole 22. When the device is not in use, the heat dissipation hole 22 is closed, and the slot plug is inserted into the dispensing slot 13 to prevent external dust and moisture from entering the dispensing box 4. This can effectively protect the internal components of the dispensing box 4 and reduce equipment maintenance costs.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
