Abstract
Description
Technical Field
[0001] This invention relates to the field of biological control technology, specifically a biological control release device and method based on natural enemy insects. Background Technology
[0002] Natural enemy insect release technology is a biological control method that uses natural enemy insects in nature to control pests, reduce the use of chemical pesticides, and thus protect the ecological environment and human health.
[0003] For ease of deployment, drones are currently the most common method for releasing predatory insects. A release device for releasing predatory insects using a drone, with publication number CN218229415U, allows for quick and easy installation of the release box onto the drone via a clamp and adjustment rod. It also ensures a uniform release quantity of predatory insects and features a release box that is easy to assemble, disassemble, clean, and has good ventilation, providing excellent containment for the predatory insects.
[0004] However, the aforementioned patent still has shortcomings. Some predatory insects will attach to the inner wall of the release box. Simply opening the release box cannot effectively release the predatory insects, which seriously affects the release quantity and efficiency and makes it inconvenient for users.
[0005] To address the aforementioned problems, an improved biological control release device and method based on natural enemy insects is now designed. Summary of the Invention
[0006] The purpose of this invention is to provide a biological control release device and method based on natural enemy insects to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A biological control release device based on predatory insects includes a drone. A mounting frame is vertically mounted on the lower end of the drone. Several release frames for placing predatory insects are provided on two opposite side walls of the mounting frame. The release frames on both sides of the mounting frame are symmetrical. The lower end of the release frame near the mounting frame's side wall is hinged to the side wall of the mounting frame. A door is provided at the end of the release frame away from the mounting frame to seal the open side of the release frame. The upper end of the door is hinged to the upper end of the release frame. A release mechanism is provided inside the release frame to sweep the predatory insects out of the release frame when it is tilted to release them. Fixing mechanisms are provided on the mounting frame and the release frames to keep the release frames horizontal before releasing the predatory insects.
[0009] As a further aspect of the present invention: the release mechanism includes two second rotating rods, and two sliding grooves are formed on two opposite side walls of the release frame. The sliding grooves are perpendicular to the open end of the release frame. A slider is slidably connected to the inner wall of the sliding groove. A first limiting plate and a second limiting plate are respectively installed at both ends of the slider. The first limiting plate is tightly attached to the side wall of the release frame, and the second limiting plate is tightly attached to the inner wall of the release frame. The two second rotating rods are arranged between the two second limiting plates, and the two second rotating rods correspond one-to-one with the two sliding grooves. A first gear is installed at both ends of the second rotating rods through the third magnet, the slider, and the first limiting plate. The second rotating rods are rotatably connected to the third magnet, the slider, and the first limiting plate. A rotating roller is installed on the side wall of the second rotating rod inside the release frame. A plurality of cleaning brushes for sweeping the predatory insects inside the release frame out of the release frame are installed on the side wall of the rotating roller. A rotating assembly for rotating the rotating roller and the cleaning brushes under the action of gravity is provided on the side wall of the release frame.
[0010] As a further embodiment of the present invention: the rotating assembly includes two fixed frames, which are respectively installed on the side wall of the release frame where the slide is located. Racks are installed on the inner walls of the fixed frames and the slide, which are parallel to each other. A third rotating rod is installed on the side wall of the first limiting plate between the first gear and the rack. A second gear that meshes with both the first gear and the rack is rotatably connected to the side wall of the third rotating rod.
[0011] As a further embodiment of the present invention: the fixing mechanism includes a third magnet, which is installed between two second limiting plates. The third magnet is located at one end of the second limiting plate away from the open side of the release frame. The interior of the mounting frame is provided with a second magnet corresponding to the release frame. One end of the second magnet is equipped with a second support plate. The end of the second support plate away from the second magnet is installed on the inner wall of the mounting frame. The polarities of the faces of the second magnet and the third magnet are opposite. The second magnet and the third magnet attract each other, causing the cleaning brush, rotating roller, and second limiting plate to move to the side of the release frame closer to the mounting frame, and keeping the release frame in a horizontal state. The interior of the mounting frame is provided with an unlocking component for releasing the attraction between the third magnet and the second magnet, causing the release frame to tilt under the action of gravity.
[0012] As a further embodiment of the present invention: the unlocking component includes a motor, which is mounted on the top of the mounting frame. A first rotating rod is mounted on the output end of the motor. The end of the first rotating rod away from the motor is rotatably connected to the bottom of the mounting frame. A screw is mounted on the side wall of the first rotating rod. An internally threaded movable sleeve is rotatably connected to the side wall of the screw via a thread. A first magnet is disposed on the side wall of the internally threaded movable sleeve near the release frame. The first magnet is disposed between a second magnet and the inner wall of the mounting frame. A first support plate is mounted on one end of the first magnet. The end of the first support plate away from the first magnet is mounted on the side wall of the internally threaded movable sleeve. The first support plate is disposed on the side of the second magnet away from the second support plate. The side of the first magnet near the release frame has the same polarity as the third magnet.
[0013] As a further embodiment of the present invention: the sidewall of the internally threaded movable sleeve moves along the inner wall of the mounting frame via ball bearings.
[0014] As a further aspect of the present invention: reinforcing support ribs for improving the structural strength of the first support plate and the second support plate are installed on the side walls of both the first support plate and the second support plate.
[0015] As a further aspect of the present invention: a counterweight is installed at the lower end of the side wall of the switch door to keep the switch door vertical.
[0016] As a further embodiment of the present invention, the mounting frame is detachably mounted on the lower end of the drone by screws.
[0017] A method for using a biological control release device based on natural enemy insects includes the following steps:
[0018] Step 1: When in use, the drone flies to the deployment area and then starts the motors via the controller.
[0019] Step 2: The output end of the motor drives the first rotating rod to rotate, which in turn drives the screw to rotate. Under the action of the thread, the screw drives the internal threaded moving sleeve to move, which in turn drives the first support plate and the first magnet to move. When the first magnet moves between the second magnet and the inner wall of the mounting frame, since the polarities of the opposing surfaces of the first magnet and the third magnet are the same, the first magnet and the third magnet generate a repulsive force. At this time, under the action of gravity and repulsive force, the release frame tilts downward, and the cleaning brush, rotating roller, and second limit plate move downward.
[0020] Step 3: Under the action of gravity, the counterweight drives the switch door to open the open end of the release frame. At the same time, the first limit plate drives the third rotating rod and the second gear to move downward. The second gear rolls along the rack, drives the first gear to rotate, the first gear drives the second rotating rod to rotate, the second rotating rod drives the rotating roller to rotate, and the rotating roller drives the cleaning brush to rotate. The cleaning brush sweeps the natural enemy insects on the inner wall of the release frame, allowing the natural enemy insects to move out through the open end of the release frame.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] After the release frame tilts downward, the present invention uses gravity to move the slider and the second limiting plate downward, thereby causing the second gear to roll along the rack, which in turn causes the rotating roller and the cleaning brush to roll. This allows the cleaning brush to sweep away the predatory insects on the inner wall of the release frame, preventing the predatory insects from adhering to the inner wall of the release frame and improving the release efficiency of the predatory insects.
[0023] This invention utilizes the mutual attraction between the second and third magnets to move the cleaning brush and the second limiting plate to one end of the release frame near the mounting frame, achieving initial fixation of the cleaning brush and horizontal fixation of the release frame. Then, through the mutual repulsion between the first and third magnets, the release frame tilts under the action of gravity, causing the slider and cleaning brush to move downwards, enabling the cleaning brush to clean the predatory insects on the inner wall of the release frame, effectively improving the fixation efficiency and release efficiency of the release frame and the second limiting plate.

[0030] 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.
[0031] Please see Figures 1-5 In this embodiment of the invention, a biological control release device based on natural enemy insects includes a drone 1. A mounting frame 2 is vertically mounted on the lower end of the drone 1. Several release frames 3 for placing natural enemy insects are provided on two opposite side walls of the mounting frame 2. The release frames 3 on both sides of the mounting frame 2 are symmetrical. The lower end of the side wall of each release frame 3 closest to the mounting frame 2 is rotatably connected to the side wall of the mounting frame 2 via a hinge. A switch door 4 for sealing the open side of the release frame 3 is provided at the end of the release frame 3 furthest from the mounting frame 2. The upper end of the switch door 4 is rotatably connected to the upper end of the release frame 3 via a hinge.

A release mechanism is provided inside each release frame 3 to sweep the natural enemy insects out of the release frame 3 when it is tilted to release them. Fixing mechanisms are provided on the mounting frame 2 and the release frame 3 to keep the release frame 3 horizontal before releasing the natural enemy insects.
[0032] The release mechanism includes two second rotating rods 19. Two sliding grooves 7 are formed on each of the two opposite side walls of the release frame 3. The sliding grooves 7 are perpendicular to the open end of the release frame 3. A slider 24 is slidably connected to the inner wall of the sliding groove 7. A first limiting plate 9 and a second limiting plate 25 are respectively installed at both ends of the slider 24. The first limiting plate 9 is tightly attached to the side wall of the release frame 3, and the second limiting plate 25 is tightly attached to the inner wall of the release frame 3. The two second rotating rods 19 are positioned between the two second limiting plates 25, and the two second rotating rods 19 are connected to the two sliding grooves 7. In a corresponding configuration, the two ends of the second rotating rod 19 pass through the third magnet 26, the slider 24, and the first limiting plate 9, and are equipped with the first gear 18. The second rotating rod 19 is rotatably connected to the third magnet 26, the slider 24, and the first limiting plate 9. A rotating roller 22 is installed on the side wall of the second rotating rod 19 inside the release frame 3. Several cleaning brushes 23 are installed on the side wall of the rotating roller 22 to sweep the predatory insects inside the release frame 3 out of the release frame 3. A rotating assembly is provided on the side wall of the release frame 3 to rotate the rotating roller 22 and the cleaning brushes 23 under the action of gravity.
[0033] The rotating assembly includes two fixed frames 6, which are respectively installed on the side wall of the release frame 3 where the slide 7 is located. A rack 8 is installed on the inner wall of each fixed frame 6 and the slide 7, which are parallel to each other.

A second gear 21 that meshes with both the first gear 18 and the rack 8 is rotatably connected to the side wall of the third rotating rod 20.
[0034] When the release frame 3 tilts downward, under the action of gravity, the first limiting plate 9, slider 24, second limiting plate 25, rotating roller 22 and cleaning brush 23 all move downward. The first limiting plate 9 drives the third rotating rod 20 and the second gear 21 to move downward. The second gear 21 rolls along the rack 8. The second gear 21 drives the first gear 18 to rotate. The first gear 18 drives the second rotating rod 19 to rotate. The second rotating rod 19 drives the rotating roller 22 to rotate. The rotating roller 22 drives the cleaning brush 23 to rotate. The cleaning brush 23 cleans the natural enemy insects on the inner wall of the release frame 3, allowing the natural enemy insects to move out through the open end of the release frame 3.
[0035] The fixing mechanism includes a third magnet 26, which is installed between two second limiting plates 25. The third magnet 26 is located at one end of the second limiting plate 25 away from the open side of the release frame 3. The interior of the mounting frame 2 is provided with a second magnet 15 corresponding to the release frame 3. A second support plate 16 is installed at one end of the second magnet 15. The end of the second support plate 16 away from the second magnet 15 is installed on the inner wall of the mounting frame 2. The polarities of the faces of the second magnet 15 and the third magnet 26 are opposite. The second magnet 15 and the third magnet 26 attract each other, causing the cleaning brush 23, the rotating roller 22, and the second limiting plate 25 to move to the side of the release frame 3 closer to the mounting frame 2, and keeping the release frame 3 in a horizontal state. The interior of the mounting frame 2 is provided with an unlocking component for releasing the attraction between the third magnet 26 and the second magnet 15, causing the release frame 3 to tilt under the action of gravity.
[0036] The unlocking assembly includes a motor 10, which is mounted on the top of the mounting frame 2. A first rotating rod 17 is mounted on the output end of the motor 10. The end of the first rotating rod 17 away from the motor 10 is rotatably connected to the bottom of the mounting frame 2. A screw 11 is mounted on the side wall of the first rotating rod 17. An internally threaded moving sleeve 12 is rotatably connected to the side wall of the screw 11 via a thread. The side wall of the internally threaded moving sleeve 12 moves along the inner wall of the mounting frame 2 via ball bearings. A first magnet 14 is provided on the side wall of the internally threaded moving sleeve 12 near the release frame 3. The first magnet 14 is located between the second magnet 15 and the inner wall of the mounting frame 2. A first support plate 13 is mounted on one end of the first magnet 14. The end of the first support plate 13 away from the first magnet 14 is mounted on the side wall of the internally threaded moving sleeve 12. The first support plate 13 is located on the side of the second magnet 15 away from the second support plate 16. The side of the first magnet 14 near the release frame 3 has the same polarity as the third magnet 26.
[0037] When in use, the motor 10 is started, and the output end of the motor 10 drives the first rotating rod 17 to rotate. The first rotating rod 17 drives the screw 11 to rotate. Under the action of the thread, the screw 11 drives the internal thread moving sleeve 12 to move. The internal thread moving sleeve 12 drives the first support plate 13 and the first magnet 14 to move. When the first magnet 14 moves between the second magnet 15 and the inner wall of the mounting frame 2, since the polarity of the opposite surfaces of the first magnet 14 and the third magnet 26 is the same, the first magnet 14 and the third magnet 26 generate a repulsive force. At this time, under the action of gravity and repulsive force, the release frame 3 tilts downward, and the cleaning brush 23, the rotating roller 22, and the second limiting plate 25 move downward.
[0038] The working principle of a biological control release device based on natural enemy insects:
[0039] When in use, the drone 1 flies to the delivery area and then the controller starts the motor 10.
[0040] The output end of the motor 10 drives the first rotating rod 17 to rotate, and the first rotating rod 17 drives the screw 11 to rotate. Under the action of the thread, the screw 11 drives the internal thread moving sleeve 12 to move. The internal thread moving sleeve 12 drives the first support plate 13 and the first magnet 14 to move. When the first magnet 14 moves between the second magnet 15 and the inner wall of the mounting frame 2, since the polarity of the opposite surfaces of the first magnet 14 and the third magnet 26 is the same, the first magnet 14 and the third magnet 26 generate a repulsive force. At this time, under the action of gravity and repulsive force, the release frame 3 tilts downward, and the cleaning brush 23, the rotating roller 22, and the second limiting plate 25 move downward.
[0041] Under the action of gravity, the counterweight 5 drives the switch door 4 to open the open end of the release frame 3. At the same time, the first limit plate 9 drives the third rotating rod 20 and the second gear 21 to move downward. The second gear 21 rolls along the rack 8, drives the first gear 18 to rotate, the first gear 18 drives the second rotating rod 19 to rotate, the second rotating rod 19 drives the rotating roller 22 to rotate, and the rotating roller 22 drives the cleaning brush 23 to rotate. The cleaning brush 23 cleans the natural enemy insects on the inner wall of the release frame 3, so that the natural enemy insects can be moved out through the open end of the release frame 3.
[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
