Description

Technical Field

[0001] The present invention relates to the technical field of agricultural and forestry prevention and control equipment, and in particular to a drone-based delivery device for adult flower beetles and a delivery method thereof. Background Art

[0002] The flower beetle is a highly effective natural enemy of the longhorn beetle, a major tree-boring pest, and plays a crucial role in controlling longhorn beetle damage. However, in large forest areas, the current practice of using this natural enemy to control longhorn beetles is to manually release them. This method is not only time-consuming and labor-intensive, but also often results in uneven and suboptimal release coverage due to dense forests and deep gullies, significantly weakening the control effect.

[0003] Currently, there are few successful cases of using drones to release flower beetles. The DJI T50 agricultural drone comes with a built-in fertilizer and seed spreader. Internally, a spiral shaft rotates to dislodge fertilizer or seeds that have sunk to the bottom. Testing has shown that adult flower beetles clump together during release, which can break them up and prevent the release of controlled numbers. Alternatively, a rotary disc can be used for spreading, but its capacity is limited, allowing only about 2,000 beetles to be released at a time, failing to meet the requirements for efficient and large-scale release within the drone's operating time. Summary of the Invention

[0004] The purpose of the present invention is to provide a drone delivery device and a delivery method for adult flower beetles, so as to solve the problem in the prior art that flower beetles cannot be effectively delivered due to clumping. The drone delivery device for adult flower beetles of the present invention can utilize the habitual state of suspended animation of adult flower beetles, and break the phenomenon of clumping of adult flower beetles during the release process through the operation of the equipment, so that the natural enemy insects, adult flower beetles, are not damaged during the release process, thereby achieving high-efficiency and damage-free release of adult flower beetles.

The bottom outlet of the material loading hopper is connected to the first end of the shaking guide, the second end of the shaking guide extends from the bottle mouth of the delivery bottle to the delivery bottle, and a feeding port is provided on the delivery bottle. The output end of the driving mechanism is connected to the end of the delivery bottle away from the bottle mouth and can drive the delivery bottle to rotate. The delivery bottle drives the shaking guide to shake, and the shaking guide drives the material loading hopper to vibrate back and forth.

[0006] As a preferred solution of the present invention, an obstacle protrusion is provided at the bottle mouth of the delivery bottle, and the obstacle protrusion is provided to protrude toward the center of the bottle mouth. When the delivery bottle rotates, the obstacle protrusion can drive the shaking guide to shake.

[0009] As a preferred solution of the present invention, the shaking guide and the delivery bottle are inclined at 10°-25° to the horizontal plane.

[0010] As a preferred solution of the present invention, the cross-section of the shaking guide gradually decreases in area from the first end to the second end.

[0011] As a preferred solution of the present invention, the feeding port is arranged on the side wall of the feeding bottle close to its bottom surface, and an adjustment sleeve is provided on the feeding bottle. The adjustment sleeve is movably arranged on the feeding bottle and can adjust the area covered at the feeding port.

[0012] As a preferred solution of the present invention, it also includes a frame, and the material hopper, shaking guide, delivery bottle and driving mechanism are all installed on the frame. A connecting rod is provided on the frame and is connected to the drone through the connecting rod.

[0013] The present invention also provides a method for releasing adult flower beetles based on the drone release device, which is characterized by comprising the steps of: Fixing the drone delivery device for the adult flower beetle on the agricultural drone; According to the number of adult flower beetles required to be released per acre of forest land and the data specified by the release equipment, adjust the speed of the release bottle and the size of the feed opening, turn the feed opening upward, and set the flight speed and route of the drone; Check that the drone is ready for takeoff and place a small amount of adult flower beetles into the loading hopper. Start the drone and fly it to the starting point of the delivery. The driving mechanism is remotely started and the drone flies according to the predetermined route and speed.

The delivery bottle drives the shaking guide to shake, and the shaking guide drives the material loading hopper to vibrate back and forth. When in use, the drone-mounted device for releasing adult flower beetles is used to release adult flower beetles into a material hopper. A driving mechanism drives a release bottle to rotate, which in turn drives a shaking guide to shake, which in turn drives the material hopper to vibrate back and forth. Because adult flower beetles have a tendency to feign death when exposed to external vibrations, the reciprocating vibration of the material hopper puts the beetles into a state of suspended animation, preventing them from clumping during release and ensuring uniform distribution. The beetles drop from the bottom outlet of the material hopper into the shaking guide and move along the guide into the release bottle. They are then evenly released through the feed opening of the release bottle, preventing the beetles from being damaged during release, thereby achieving efficient and damage-free release of the beetles.

In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0018] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention depending on the specific circumstances.

[0019] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1: This embodiment provides a drone delivery device for adult flower beetles, such as Figures 1-6 As shown, the device comprises a loading hopper 1, a shaking guide 2, a delivery bottle 3, and a drive mechanism 4. The bottom outlet 13 of the loading hopper 1 is connected to the first end 21 of the shaking guide 2. The loading hopper 1 is used to load adult flower beetles. The second end 22 of the shaking guide 2 extends from the bottle opening 31 of the delivery bottle 3 into the delivery bottle 3. A delivery port 32 is provided on the delivery bottle 3 for releasing the flower beetles. The bottom outlet 13 of the loading hopper 1 is connected to the delivery bottle 3 via the shaking guide 2.

[0021] The output end of the drive mechanism 4 is connected to the end of the delivery bottle 3 facing away from the bottle opening 31 and is capable of driving the delivery bottle 3 to rotate. The delivery bottle 3 causes the shaking guide 2 to vibrate, which in turn causes the material loading hopper 1 to vibrate back and forth. Preferably, a connection hole 34 is provided at the center of the bottom surface of the delivery bottle 3. The output end of the drive mechanism 4 connects to this hole 34 to drive the delivery bottle 3. The drive mechanism 4 utilizes a variable voltage reduction motor, which consumes little power and essentially does not require the drone's battery power. Alternatively, a separate power supply can be provided.

[0022] When in use, the drone-mounted device for releasing adult flower beetles of this embodiment releases adult flower beetles into a loading hopper 1. A driving mechanism 4 rotates the release bottle 3, which in turn causes the shaking guide 2 to shake. This in turn causes the loading hopper 1 to vibrate back and forth. Because adult flower beetles have a tendency to feign death when exposed to external vibrations, the reciprocating vibration of the loading hopper 1 causes the beetles to remain in a state of suspended animation, preventing them from clumping during release and ensuring uniform distribution. The beetles drop from the bottom outlet 13 of the loading hopper 1 into the shaking guide 2, slide along the shaking guide 2 into the release bottle 3, and are evenly released through the feeding port 32 of the release bottle 3. This prevents the beetles from being damaged during release, achieving efficient and damage-free release of the beetles.

[0023] As a preferred embodiment, Figure 1 and Figure 4 As shown, a barrier protrusion 5 is provided at the mouth 31 of the delivery bottle 3, projecting toward the center of the mouth 31. When the delivery bottle 3 rotates, the barrier protrusion 5 can cause the shaking guide 2 to shake. The barrier protrusion 5 can be integral with the delivery bottle 3 or attached to the delivery bottle 3 by means of adhesive, screws, or other methods.

[0024] In this embodiment, an obstacle protrusion 5 is provided at the bottle mouth 31 of the delivery bottle 3. When the driving mechanism 4 drives the delivery bottle 3 to rotate, the obstacle protrusion 5 can move the shaking guide 2, causing the shaking guide 2 to shake regularly. Moreover, since the second end 22 of the shaking guide 2 extends into the delivery bottle 3, the bottle mouth 31 of the delivery bottle 3 can limit the shaking amplitude of the shaking guide 2.

[0025] As a preferred embodiment, the material loading hopper 1 includes a fixed arc surface 11 and a movable arc surface 12. The movable arc surface 12 is movably connected relative to the fixed arc surface 11, and the fixed arc surface 11 and the movable arc surface 12 are spliced ​​to form a funnel-shaped structure. The shaking guide 2 can drive the movable arc surface 12 to vibrate back and forth. The area of ​​the fixed arc surface 11 is larger than the area of ​​the movable arc surface 12. The fixed arc surface 11 is extended in the direction close to the delivery bottle 3 to increase the loading capacity of the material loading hopper 1. Preferably, the fixed arc surface 11 is connected to the frame, and the upper side of the movable arc surface 12 is connected to the fixed arc surface 11 and the frame. The movable arc surface 12 is made of elastic material. The movable arc surface 12 can be made of a bent plastic plate, and the fixed arc surface 11 can also be made of a bent plastic plate. Preferably, the bottom end of the movable arc surface 12 extends to the lower side of the fixed arc surface 11 and forms a bottom outlet 13 opening toward the delivery bottle 3 between the bottom side of the fixed arc surface and the lower side of the fixed arc surface.

[0026] When the shaking guide 2 shakes, it can drive the movable arc surface 12 to vibrate, thereby causing the adult flower beetles in the loading hopper 1 to fall.

[0027] As a preferred embodiment, Figure 1 and Figure 3 As shown, the first end 21 of the shaking guide 2 has a connecting groove 23 that opens upward, and the bottom outlet 13 of the material loading hopper 1 is connected to the connecting groove 23. The second end 22 of the shaking guide 2 is provided with a discharge port 24, and the discharge port 24 extends into the delivery bottle 3. The discharge port 24 is connected to the connecting groove 23 through the guide channel inside the shaking guide 2. Preferably, the bottom outlet 13 of the material loading hopper 1 is opened to one side of the delivery bottle 3 and is connected to the guide channel inside the shaking guide 2. The bottom end of the material loading hopper 1 is engaged with the connecting groove 23 so that the shaking of the material loading hopper 1 can drive the deformation and vibration of the bottom end of the material loading hopper 1. Preferably, the connecting groove 23 gradually increases from the opening close to the delivery bottle 3 to the side away from the delivery bottle 3, and the bottom end of the material loading hopper 1 is arranged on the side of the connecting groove 23 close to the delivery bottle 3. As shown Figure 1 As shown, the delivery bottle 3 is arranged on the left side of the shaking guide 2, and the connecting groove 23 extends to the right side of the bottom end of the material loading hopper 1.

[0028] In addition, the upper opening of the connecting groove 23 can also be a circular structure, and the bottom outlet 13 of the material loading hopper 1 is inserted into the upper opening of the connecting groove 23, so that the bottom outlet 13 of the material loading hopper 1 is connected to the connecting groove 23, and the shaking of the shaking guide 2 can drive the material loading hopper 1 to vibrate.

[0029] As a preferred embodiment, the shaking guide 2 and the delivery bottle 3 are inclined at 10°-25° to the horizontal plane. Preferably, the shaking guide 2 and the delivery bottle 3 are on the same straight line, and the angle α between the delivery bottle 3 and the horizontal plane is 15°.

[0030] Preferably, the shaking guide 2 is made of elastic material, and the shaking guide 2 can be made of plastic material.

[0031] The tilted arrangement of the shaking guide 2 and the delivery bottle 3 in this embodiment facilitates the movement of adult flower beetles into the delivery bottle 3 under the action of gravity, allowing them to move toward the feeding port 32 at the bottom of the delivery bottle 3. This encourages the adult flower beetles to move downward under their own gravity, and the shaking shaking guide 2 delivers a small number of them into the delivery bottle 3, ensuring a uniform release of the adult flower beetles. When the delivery bottle 3 is rotated so that the feeding port 32 opens downward, the adult beetles fall through the feeding port 32 under the action of gravity, thereby being delivered.

[0032] As a preferred embodiment, the cross-section of the shaking guide 2 gradually decreases in area from its first end 21 to its second end 22, and the aperture of the guide channel gradually decreases from its first end 21 to its second end 22, so that the adult flower beetles can move in a limited amount through the guide channel in the shaking guide 2 to the delivery bottle 3, making the guidance smoother.

[0033] In a preferred embodiment, the feeding port 32 is provided on the side wall of the feeding bottle 3 near its bottom surface. The feeding bottle 3 is tilted to facilitate the gathering of the adult flower beetles in the feeding bottle 3 toward its bottom surface and to be fed through the feeding port 32. Preferably, the aperture of the feeding port 32 is 2 cm*4.5 cm.

[0034] An adjustment sleeve 33 is mounted on the feeding bottle 3. The adjustment sleeve 33 is movably mounted on the feeding bottle 3 and can adjust the area covered at the feeding port 32. The adjustment sleeve 33 can adjust the effective aperture of the feeding port 32 to finely adjust the release rate of the adult flower beetles.

[0035] As a preferred embodiment, the drone delivery device for adult flower beetles of this embodiment further includes a frame 6, on which the material hopper 1, shaking guide 2, delivery bottle 3, and drive mechanism 4 are mounted. A connecting rod 61 is provided on the frame 6 and connected to the drone via the connecting rod 61. Two connecting rods 61 are provided, and both connecting rods 61 are connected to the top of the frame 6. Preferably, the frame 6 has a boat-like structure, closed on all sides and open at the top and bottom. Preferably, a support rod 62 is provided at the bottom end of the frame 6. There can be two support rods 62, which form the drive mechanism 4 and delivery bottle 3. The upper opening of the frame 6 facilitates the delivery of adult flower beetles into the material hopper 1, while the lower opening of the frame 6 allows the beetles in the delivery bottle 3 to be effectively released. The enclosing panels around the frame 6 prevent external interference with the beetles' movement between the material hopper 1, shaking guide 2, and delivery bottle 3. The boat-like structure of the frame 6 reduces the effects of wind resistance during use. Trademarks and texts can be attached to the outside of the frame 6.

[0036] Preferably, if Figure 2 As shown, the upper portion of the fixed arc surface 11, away from the movable arc surface 12, is connected to the frame 6 via a second connection point 15. The upper portions of the fixed arc surface 11 and the movable arc surface 12, where they are closer to each other, are each connected to the frame 6 via a first connection point 14. The bottom side of the fixed arc surface 11 is connected to the frame 6 via a third connection point 16. The first end 21 of the shaking guide 2 is connected to the frame 6 via a fourth connection point 25. Each of these connection points can be connected to the side panels of the frame 6 via bolts or pins.

[0037] In addition, the frame 6 can also be designed into other shapes as needed.

[0038] Preferably, the drone delivery device for adult flower beetles of this embodiment also includes a circuit control system and a power source. The power source includes a power supply. The driving mechanism is connected to the power supply via a connecting wire. The circuit control system includes a signal instruction receiver. The signal instruction receiver is used to receive control instructions and control the operation of the driving mechanism.

[0039] This embodiment also provides a method for releasing adult flower beetles based on a drone-based release device, which is characterized by comprising the steps of: Fix the drone-based delivery equipment for adult flower beetles on the agricultural drone; before that, remove the spraying equipment or fertilizer spreading equipment on the agricultural drone.

[0040] According to the number of adult flower beetles required to be released per acre of forest land and the data specified by the release equipment, the rotation speed of the release bottle 3 and the size of the feed port 32 are adjusted, and the feed port 32 is turned upward, and the flight speed and route of the drone are set.

[0041] Check that the drone is ready for takeoff, that all signals are sufficient, and that the battery is fully charged. First, place a small number of adult flower beetles into hopper 1. The adults will clump together and block the lower exit. Then, pour all the adult beetles into hopper 1.

[0042] The drone is started to fly to the air above the starting point of the release, and the driving mechanism 4 is remotely activated, and the drone flies according to the predetermined route and speed to complete the task of releasing the adult flower beetles.

[0043] When using drones to release adult flower beetles, the desired release rate per acre can be set. Adjusting the voltage changes the speed of the release bottle, from 20 to 70 times per minute. Fine-tune the release port to ensure a more consistent release rate per minute (reference data: an average of 13.42 beetles per time). The drone's flight path is then determined based on its optimal speed to ensure a consistent release rate per acre.

[0044] Table 1 below shows the drop yield per acre based on the drop rate per minute and the drone's operating speed. This data can be used as a reference for drone deployment. As can be seen, when the number of drops per minute is determined, the faster the drone's operating speed, the smaller the drop yield per acre, but the larger the area covered by the drone. When the drone's operating speed is determined, the higher the drop rate per minute, the larger the drop yield per acre, without affecting the area covered by the drone. You can choose the appropriate drone operating time and drop rate per minute based on your needs.

[0045]

[0046] Table 1 The flight paths in Table 1 above are calculated based on a 13-meter flight interval and two 26-meter passes per acre. The calculation formula is as follows.

[0047] Formula 1: X=26*2 / V / T*13.42 Formula 2: T = 60 / M Where X: number of drones released per mu (heads); V: drone operating speed (m / s); T: time it takes for a drone to release drones once (seconds); M: rotation speed (times / minute).

[0048] The method for releasing adult flower beetles based on drone-based equipment in this embodiment utilizes the habit of adult flower beetles to feign death when encountering external vibrations, and regularly vibrates to evenly spread the adults. By connecting and operating with drones, large-scale, high-efficiency, full-coverage, and damage-free release of flower beetles in the forest is achieved. The loading capacity is large, and up to 100,000 adult flower beetles can be loaded at a time as needed, meeting the 10-30 minute continuous operation of agricultural drones. The main body of the release auxiliary equipment is made of plastic and is light in weight, which can be controlled to be less than 1.2 kilograms. 100,000 adult flower beetles weigh about 2.2 kilograms, and the total load does not exceed 4 kilograms. The drone consumes less energy and has a long flight time. At the same time, the number of releases per minute and the number of individuals released each time can be controlled to meet the actual needs of the number of natural enemy insects required for different prevention and control areas, and the effect is very ideal.

[0049] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with this technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
