Description

Technical Field

[0001] This invention relates to the field of agricultural and forestry pest control equipment technology, and in particular to a drone-based device and method for deploying adult flower beetles. Background Technology

[0002] The flower-tailed parasitic beetle is an excellent natural enemy of longhorn beetles, a major timber borer in forests, and plays a crucial role in controlling their damage. However, in large-scale forest areas, the actual practice of using this natural enemy to control longhorn beetles currently relies on manual release. This method is not only time-consuming and labor-intensive, but also often results in uneven release and unsatisfactory 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 the flower beetle. The DJI T50 agricultural drone comes with a device for spreading fertilizer and seeds, which uses an internal drive screw shaft to bring up fertilizer or seeds that have sunk to the bottom. Tests have shown that the flower beetle adults clump together during release, which this device can break up, and it cannot control the number released. Another method is to use a rotating seeding disc, but its capacity is limited, releasing only about 2,000 beetles at a time, which cannot meet the needs of effectively releasing large numbers of flower beetle adults within the drone's effective operating time. Summary of the Invention

[0004] The purpose of this invention is to provide a drone-based release device and method for adult parasitic beetles, which solves the problem that the parasitic beetles cannot be effectively released due to their clumping together in the prior art. The drone-based release device for adult parasitic beetles of this invention can utilize the parasitic beetle's dormant state and break up the clumping phenomenon during the release process by operating the device. This ensures that the beetles are not damaged during the release of their natural enemy, thus achieving a highly efficient and damage-free release of adult parasitic beetles.

[0005] This invention provides a drone-based device for dispensing adult flower beetles, comprising a material hopper, a shaking guide, a dispensing bottle, and a drive mechanism. The bottom outlet of the material hopper is connected to a first end of the shaking guide, and a second end of the shaking guide extends from the mouth of the dispensing bottle into the bottle. A feeding port is provided on the dispensing bottle. The output end of the drive mechanism is connected to the end of the dispensing bottle opposite to the mouth and can drive the dispensing bottle to rotate. The dispensing bottle causes the shaking guide to shake, and the shaking guide causes the material hopper to vibrate reciprocally.

[0006] As a preferred embodiment of the present invention, an obstacle protrusion is provided at the mouth of the dispensing bottle, the obstacle protrusion protruding towards the center of the bottle mouth, and the obstacle protrusion can cause the shaking guide to shake when the dispensing bottle is rotated.

[0007] As a preferred embodiment of the present invention, the material hopper includes a fixed arc surface and a movable arc surface, the movable arc surface being movably connected to the fixed arc surface, the fixed arc surface and the movable arc surface being spliced ​​together to form a funnel-shaped structure, and the shaking guide can drive the movable arc surface to reciprocate.

[0008] As a preferred embodiment of the present invention, the first end of the shaking guide has an upward-opening connecting groove, the bottom outlet of the material hopper is connected to the connecting groove, the second end of the shaking guide is provided with a discharge port, the discharge port extends into the dispensing bottle, and the discharge port is connected to the connecting groove through a guide channel inside the shaking guide.

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

[0010] As a preferred embodiment of the present invention, the cross-sectional area of ​​the shaking guide gradually decreases from its first end to its second end.

[0011] As a preferred embodiment of the present invention, the feeding port is disposed on the side wall of the feeding bottle near its bottom surface, and an adjusting sleeve is fitted on the feeding bottle. The adjusting sleeve is movably disposed on the feeding bottle and can adjust the area covering the feeding port.

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

[0013] The present invention also provides a deployment method based on the aforementioned drone deployment device for adult flower beetles, characterized by comprising the following steps:

[0014] The drone delivery equipment for adult flower velvet beetles is fixed to an agricultural drone;

[0015] Based on the number of adult flower velvet beetles required per acre of forest land and the data specified by the release equipment, adjust the rotation speed of the release bottle and the size of the release nozzle, turn the release nozzle upwards, and set the drone's flight speed and route.

[0016] After checking that the drone is ready for takeoff, first put a small number of adult flower beetles into the material hopper;

[0017] The drone is launched and flies to the starting point for deployment. The drive mechanism is remotely activated, and the drone flies along the predetermined route and speed.

[0018] Compared with the prior art, the present invention has the following positive effects:

[0019] The present invention provides a drone-based delivery device for adult flower beetles, comprising a material hopper, a shaking guide, a delivery bottle, and a drive mechanism. The bottom outlet of the material hopper is connected to the first end of the shaking guide, and the second end of the shaking guide extends from the mouth of the delivery bottle into the delivery bottle. A feeding port is provided on the delivery bottle. The output end of the drive mechanism is connected to the end of the delivery bottle opposite to the mouth and can drive the delivery bottle to rotate. The delivery bottle causes the shaking guide to shake, and the shaking guide causes the material hopper to vibrate reciprocally. In use, the drone-based release device for adult flower beetles of this invention releases adult flower beetles into the material hopper. A drive mechanism rotates the release bottle, which in turn causes a shaking guide to vibrate. This vibration, in turn, causes the material hopper to vibrate repeatedly. Since adult flower beetles exhibit a tendency to feign death upon exposure to external vibrations, the reciprocating vibration of the material hopper keeps them in a state of suspended animation, preventing them from clumping together during release and ensuring even distribution. The adult flower beetles fall from the bottom outlet of the material hopper into the shaking guide and move along it to the release bottle. They are then evenly released through the bottle's inlet, preventing damage to the predatory insects during the release process. This achieves highly efficient and damage-free release of the flower beetles. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0031] Example 1:

[0032] This embodiment provides a drone-based device for deploying adult flower beetles, such as... Figures 1-6As shown, the device includes a material hopper 1, a shaking guide 2, a dispensing bottle 3, and a driving mechanism 4. The bottom outlet 13 of the material hopper 1 is connected to the first end 21 of the shaking guide 2. The material 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 dispensing bottle 3 into the dispensing bottle 3. A feeding port 32 is provided on the dispensing bottle 3 for releasing the flower beetles. The bottom outlet 13 of the material hopper 1 is connected to the dispensing bottle 3 via the shaking guide 2.

[0033] The output end of the drive mechanism 4 is connected to the end of the dispensing bottle 3 away from the bottle opening 31 and can drive the dispensing bottle 3 to rotate. The dispensing bottle 3 drives the shaking guide 2 to shake, and the shaking guide 2 drives the material hopper 1 to vibrate back and forth. Preferably, a connecting hole 34 is provided at the center of the bottom surface of the dispensing bottle 3, and the output end of the drive mechanism 4 is connected to the connecting hole 34 to drive the dispensing bottle 3 to rotate. The drive mechanism 4 adopts a variable voltage geared motor, which has low power consumption and basically does not occupy the power supply of the drone battery. It can also be equipped with a separate power supply.

[0034] In this embodiment, the drone-based release device for adult flower beetles releases the beetles into the material hopper 1. The drive mechanism 4 rotates the release bottle 3, which in turn causes the shaking guide 2 to vibrate. The shaking guide 2 then causes the material hopper 1 to vibrate back and forth. Since adult flower beetles have the habit of feigning death when exposed to external vibrations, the reciprocating vibration of the material hopper 1 keeps the beetles in a state of feigned death, preventing them from clumping together during release and ensuring even distribution. The adult flower beetles fall from the bottom outlet 13 of the material hopper 1 into the shaking guide 2 and slide along it into the release bottle 3. The beetles are then evenly released through the feeding port 32 of the release bottle 3, preventing damage to the beetles during the release of their natural enemy, thus achieving a highly efficient and damage-free release of the beetles.

[0035] As a preferred embodiment, such as Figure 1 and Figure 4 As shown, an obstacle protrusion 5 is provided at the mouth 31 of the dispensing bottle 3, protruding towards the center of the mouth 31. When the dispensing bottle 3 rotates, the obstacle protrusion 5 can cause the shaking guide 2 to shake. The obstacle protrusion 5 can be an integral part of the dispensing bottle 3, or it can be connected to the dispensing bottle 3 by means of adhesive, screws, etc.

[0036] In this embodiment, by providing an obstacle protrusion 5 at the bottle opening 31 of the dispensing bottle 3, when the driving mechanism 4 drives the dispensing bottle 3 to rotate, the obstacle protrusion 5 can move the shaking guide 2, causing the shaking guide 2 to shake regularly. Furthermore, since the second end 22 of the shaking guide 2 extends into the dispensing bottle 3, the bottle opening 31 of the dispensing bottle 3 can limit the shaking amplitude of the shaking guide 2.

[0037] In a preferred embodiment, the material hopper 1 includes a fixed arc surface 11 and a movable arc surface 12, which are movably connected to the fixed arc surface 11. The fixed arc surface 11 and the movable arc surface 12 are joined to form a funnel-shaped structure. The shaking guide 2 can drive the movable arc surface 12 to vibrate reciprocally. The area of ​​the fixed arc surface 11 is larger than the area of ​​the movable arc surface 12, and the fixed arc surface 11 extends towards the dispensing bottle 3 to increase the loading capacity of the material 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 an elastic material and can be made of bent plastic sheet. The fixed arc surface 11 can also be made of bent plastic sheet. 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 that opens towards the dispensing bottle 3.

[0038] When the shaking guide 2 shakes, it can drive the movable arc surface 12 to vibrate, thereby causing the adult flower velvet beetles in the material hopper 1 to fall.

[0039] As a preferred embodiment, such as Figure 1 and Figure 3 As shown, the first end 21 of the shaking guide 2 has an upward-opening connecting groove 23, and the bottom outlet 13 of the material 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, which extends into the dispensing bottle 3. The discharge port 24 communicates with the connecting groove 23 through a guide channel inside the shaking guide 2. Preferably, the bottom outlet 13 of the material hopper 1 is opened towards the dispensing bottle 3 and is connected to the guide channel inside the shaking guide 2. The bottom end of the material hopper 1 is engaged with the connecting groove 23 so that the shaking of the material hopper 1 can cause the bottom end of the material hopper 1 to deform and vibrate. Preferably, the opening of the connecting groove 23 gradually increases from the side closer to the dispensing bottle 3 to the side farther away from the dispensing bottle 3, and the bottom end of the material hopper 1 is located on the side of the connecting groove 23 closer to the dispensing bottle 3. Figure 1 As shown, the dispensing bottle 3 is located on the left side of the shaking guide 2, and the connecting groove 23 extends to the right side of the bottom of the material hopper 1.

[0040] Alternatively, the upper opening of the connecting groove 23 can also be a circular structure. The bottom outlet 13 of the material hopper 1 is inserted into the upper opening of the connecting groove 23, thereby connecting the bottom outlet 13 of the material hopper 1 with the connecting groove 23, and enabling the shaking of the shaking guide 2 to drive the material hopper 1 to vibrate.

[0041] In one preferred embodiment, the shaking guide 2 and the dispensing bottle 3 are inclined at 10°-25° to the horizontal plane. Preferably, the shaking guide 2 and the dispensing bottle 3 are on the same straight line, and the angle α between the dispensing bottle 3 and the horizontal plane is 15°.

[0042] Preferably, the vibration guide 2 is made of an elastic material, or it can be made of plastic.

[0043] In this embodiment, the shaking guide 2 and the dispensing bottle 3 are tilted, which allows the adult flower beetles to move easily into the dispensing bottle 3 under the action of gravity. This also allows the adult flower beetles in the dispensing bottle 3 to move towards the feeding port 32 at its bottom, causing them to move downwards under their own gravity. The shaking guide 2 then delivers a small number of these adult flower beetles into the dispensing bottle 3, ensuring even release. When the dispensing port 32 of the dispensing bottle 3 is rotated downwards, the adult beetles will fall from the dispensing port 32 under the action of gravity, thus achieving dispensing.

[0044] In a preferred embodiment, the cross-sectional area of ​​the shaking guide 2 gradually decreases 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 velvet beetle can move in a limited amount through the guide channel to the delivery bottle 3 in the shaking guide 2, making the guidance smoother.

[0045] In a preferred embodiment, the feeding port 32 is located on the side wall of the feeding bottle 3 near its bottom surface. The feeding bottle 3 is tilted to facilitate the gathering of adult flower beetles on its bottom surface and their release through the feeding port 32. Preferably, the diameter of the feeding port 32 is 2cm*4.5cm.

[0046] An adjusting sleeve 33 is fitted onto the feeding bottle 3. The adjusting sleeve 33 is movably mounted on the feeding bottle 3 and can adjust the area covering the feeding port 32. The adjusting sleeve 33 can adjust the effective aperture of the feeding port 32 to finely adjust the feeding rate of adult flower beetles.

[0047] In a preferred embodiment, the drone-based insect delivery device for adult *Pterocarya stenoptera* in this embodiment further includes a frame 6, on which a material hopper 1, a shaking guide 2, a delivery bottle 3, and a drive mechanism 4 are all mounted. Connecting rods 61 are provided on the frame 6 and connected to the drone via these rods. Two connecting rods 61 are provided, connected to the top of the frame 6. Preferably, the frame 6 has a boat-shaped structure with closed sides and open top and bottom. Preferably, a support rod 62 is provided at the bottom of the frame 6, which can be two, used to form the drive mechanism 4 and the delivery bottle 3. The upper opening of the frame 6 facilitates the delivery of adult *Pterocarya stenoptera* into the material hopper 1, while the lower opening of the frame 6 allows the *Pterocarya stenoptera* in the delivery bottle 3 to be effectively released and fall. The closed sides of the frame 6 prevent external interference with the transfer of *Pterocarya stenoptera* between the material hopper 1, the shaking guide 2, and the delivery bottle 3. The boat-shaped structure of the frame 6 reduces wind resistance during use. Logos and text can be attached to the exterior of rack 6.

[0048] Preferably, such as Figure 2 As shown, the upper part of the fixed arc surface 11 on the side away from the movable arc surface 12 is connected to the frame 6 via the second connection point 15. The upper parts of the fixed arc surface 11 and the movable arc surface 12 on the side closer to each other are connected to the frame 6 via the first connection point 14. The bottom side of the fixed arc surface 11 is connected to the frame 6 via the third connection point 16. The first end 21 of the shaking guide 2 is connected to the frame 6 via the fourth connection point 25. All of the above connection points can be connected to the side plate of the frame 6 by bolts or pins.

[0049] In addition, rack 6 can also be designed in other shapes as needed.

[0050] Preferably, the drone delivery device for adult flower beetle in this embodiment further includes a circuit control system and a power source. The power source includes a power supply, and the drive mechanism is connected to the power supply via a connecting wire. The circuit control system includes a signal command receiver, which is used to receive control commands and control the operation of the drive mechanism.

[0051] This embodiment also provides a deployment method based on a drone deployment device for adult flower beetles, characterized by including the following steps:

[0052] The drone delivery equipment for adult flower beetles is fixed to the agricultural drone; before that, the spraying equipment or fertilizer spreading equipment on the agricultural drone can be removed.

[0053] Based on the number of adult flower velvet beetles required per acre of forest land and the data specified by the release equipment, adjust the rotation speed of release bottle 3 and the size of release port 32, turn release port 32 upwards, and set the drone's flight speed and route.

[0054] Check that the drone is ready for takeoff, all signals are strong, and the battery is fully charged. First, put a small number of adult parasitic beetles into the material hopper 1. The adults will clump together and block the lower outlet. Then, pour all the adult parasitic beetles released this time into the material hopper 1.

[0055] The drone is launched and flies to the starting point of the release. Drive mechanism 4 is remotely activated, and the drone flies along the predetermined route and speed, completing the task of releasing adult flower beetles.

[0056] When using drones to release adult flower beetles, the release rate per acre can be set according to needs. Adjust the voltage to change the rotation speed of the release bottle, from 20 times per minute to 70 times per minute. Fine-tune the release nozzle of the release bottle to ensure a more even release rate per minute (reference average data: 13.42 beetles / release). Then, determine the drone's flight path based on its appropriate speed to ensure the release rate per acre.

[0057] Table 1 below shows the drop volume per acre corresponding to two factors: drop rate per minute and drone operating speed. This data can be used as a reference during drone deployment. It can be seen that when the number of drops per minute is fixed, the faster the drone's operating speed, the smaller the drop volume per acre, and the larger the area the drone can cover. When the drone's operating speed is fixed, the more drops per minute, the greater the drop volume per acre, without affecting the area covered. Appropriate drone operating time and drop frequency per minute can be selected based on individual requirements.

[0058]

[0059] Table 1

[0060] The flight routes in Table 1 above are calculated based on a flight spacing of 13 meters, with each acre passing through twice at a distance of 26 meters. The calculation formula is as follows.

[0061] Formula 1: X = 26 * 2 / V / T * 13.42

[0062] Formula 2: T = 60 / M

[0063] Where X: number of drones deployed per acre (heads); V: drone operating speed (m / s); T: time taken for one drone deployment (seconds); M: rotation speed (times / minute).

[0064] This embodiment describes a method for releasing adult parasitic beetles using a drone-based device. Utilizing the beetles' tendency to feign death upon exposure to vibration, the device uses rhythmic vibration to evenly disperse the beetles. By connecting and operating with a drone, it achieves large-scale, efficient, comprehensive, and damage-free release of the beetles in forests. It has a large carrying capacity, capable of carrying up to 100,000 adult beetles at a time, sufficient for 10 to 30 minutes of continuous operation by agricultural drones. The main body of the release auxiliary equipment is made of plastic, making it lightweight and under 1.2 kg. 100,000 adult beetles weigh approximately 2.2 kg, with a total payload not exceeding 4 kg. The drone consumes little energy and has a long flight time. Furthermore, by controlling the number of releases per minute and the number of individuals released each time, it can meet the actual needs of different control areas requiring a specific number of natural enemy insects, resulting in highly effective control.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present invention should be covered within the scope of protection of the present invention.
