Technical Field
[0001] This invention relates to the field of green pest control technology, specifically to a wind-suction plant protection device with a secondary natural enemy screening function. Background Technology
[0002] Currently, the wind-suction insecticidal lamp is a common plant protection device. It attracts pests by emitting light of specific wavelengths, and then uses a fan to suck the pests into a collection bin, thereby killing them. This type of insecticidal lamp uses different light wavelengths to filter between natural enemies and pests, achieving a natural enemy-friendly effect. It has advantages such as simple structure, convenient operation, no pollution, and no noise, and is widely used in agriculture, forestry, horticulture, animal husbandry, and other fields.
[0003] For example, a smart biomimetic frequency synthesis variable spectrum stroboscopic insecticidal lamp device, disclosed in patent number "CN107047506B", uses a program that determines when there is no rain or human or animal activity in the vicinity to invoke a biomimetic frequency synthesis variable light band program. This program continuously and automatically tracks different types and species of pests and outputs light band signals of the phototactic frequencies that the pests are sensitive to through program control. These signals are amplified to control the lamp's operation. Each lamp is powered by a constant current source, ensuring long-term stable and reliable operation. This control not only includes frequency synthesis but also PWM modulation. This program can concentrate energy and light bands to attract and kill target pests, improving energy utilization, reducing light pollution, and simultaneously reducing attraction to beneficial insects, thus protecting biodiversity.
[0004] This invention uses a single LED light source to attract insects with different spectra and traps them by suction, which is highly efficient. However, even with a specific spectrum, some natural enemies will still be attracted or mistakenly preyed upon. The device does not treat the captured natural enemies, which means that they are still somewhat harmful to them.
[0005] For example, the utility model patent number "CN219288537U" describes a three-dimensional cloud-based photo recognition insecticidal lamp. The lamp's controller operates, attracting insects to the light source. An electric shock net and impact plate knock the insects down, while a fan generates suction, drawing the insects from the lower casing's vents into the insect-collecting container, or onto the outer wall of the insect escape-prevention net, where they slide into the container. Insects surviving in the container are prevented from flying out by the downward airflow from the fan and the escape-prevention net. A camera captures real-time images of the insects in the container and uploads them to a cloud server. The cloud server processes and stores the images, allowing for real-time viewing of both the image data and historical data.
[0006] This utility model identifies trapped pests by taking pictures and can monitor the capture of pests and their natural enemies in real time. However, it does not operate the device based on the results of the picture recognition. The picture is just a picture and does not screen pests and their natural enemies to reduce the false killing rate.
[0007] However, existing light-attracting wind-suction insecticidal lamps often use a single, specific spectrum of light to lure pests. The spectrum is usually selected based on maximizing the attraction to the target pests, without considering the attraction of natural enemies to the light source. Even if the equipment uses a light source with a low attraction rate to natural enemies, it is still difficult to effectively screen out and remove natural enemies after they are accidentally captured by the equipment, resulting in a high rate of accidental killing of natural enemies. If this leads to the killing of a large number of natural enemy insects in the environment, it will affect or even destroy the balance of the ecosystem. It will not only fail to kill pests, but may also lead to more serious pest damage and reduced agricultural production.
[0008] Therefore, we propose a wind-suction plant protection device with a secondary natural enemy screening function to solve the problems mentioned above. Summary of the Invention
[0009] The purpose of this invention is to provide a wind-suction plant protection device with a secondary natural enemy screening function, in order to solve the problem mentioned in the background art that uses a single LED light source to attract insects with different spectra and traps them by suction. While this method has a high insect trapping efficiency, even with a specific spectrum, some natural enemies will still be attracted or mistakenly caught. The device does not process the captured natural enemies, resulting in some lethality to them. Furthermore, the device does not operate based on the results of image recognition; the image capture is merely a snapshot and does not achieve the screening of pests and natural enemies to reduce the false kill rate.
[0010] To achieve the above objectives, the present invention provides the following technical solution: a wind-suction plant protection device with a secondary natural enemy screening function, comprising a support frame, wherein a control box and an insect collection tray are bolted to the upper front of the support frame, and channels are fixedly connected to both the left and right sides of the insect collection tray.

[0012] LED lights are installed on the inner walls of both channels, and a first fan is rotatably connected to the upper part of the inner walls of both channels via a shaft. A first motor is bolted to the top of the left channel, and the shaft end of the first fan on the left is fixedly connected to the output end of the first motor. The outer sides of the shaft ends of the two first fans are connected by a first pulley assembly.
[0013] Both channels are connected to the interior of the insect collection tray via connecting pipes. A partition plate is fixed in the middle of the interior of the insect collection tray. A natural enemy storage area is provided on the left side of the partition plate inside the insect collection tray, and a pest storage area is provided on the right side of the partition plate inside the insect collection tray.
[0014] A second fan and a camera are bolted to the top of the insect storage area, and an electric grid is installed below the insect storage area. Openings are provided on the left and right sides of the bottom of the insect collection tray, and the inner walls of the two openings are respectively provided with a first movable plate and a second movable plate.
[0015] A second motor is bolted to the lower right side of the insect collecting tray. A shaft is connected to the lower bearing inside the insect collecting tray, and the right end of the shaft passes through the interior of the insect collecting tray. The right end of the shaft is fixedly connected to the output end of the second motor.
[0016] Preferably, the LED light on the left has a wavelength of 450 nm, and the LED light on the right has a wavelength of 385 nm, which can attract pests and natural enemies respectively.
[0017] Preferably, a sleeve is fitted on the outer side of the left end of the shaft, the second movable plate is fitted and fixed on the outer side of the sleeve, the first movable plate is fitted and fixed on the outer side of the shaft, and a ratchet assembly block is installed between the shaft and the sleeve.
[0018] Preferably, guide seats are fixed on both the left and right sides of the first movable plate, and a bonding block is provided between the two guide seats. Slider blocks are slidably connected to the inner walls of the two bonding blocks, and a scraper is fixedly connected between the two slider blocks.
[0019] Preferably, the bottom of the scraper is in contact with the surface of the first movable plate, and the slider and the groove are both arranged in a "T" shape.
[0020] Preferably, the left and right sides of the electric grid are slidably connected to the inner wall of the insect collecting tray, the top two sides of the electric grid are fitted with return springs between them and the inner wall of the insect collecting tray, and the bottom two sides of the electric grid are fixed with fitting blocks. A transmission rod is provided inside the insect collecting tray below the electric grid, and cams are fitted and fixed on the outer side of the transmission rod.
[0021] Preferably, the right end of the transmission rod passes through the interior of the insect collecting disc, and the transmission rod and the insect collecting disc are rotatably connected, and the right end of the transmission rod is fixedly connected to the output end of the second motor.
[0022] Preferably, the positions of the bonding block and the cam are in one-to-one correspondence, and the bottom of the bonding block is bonded to the outer side of the cam.
[0023] Preferably, the transmission rod is connected to the outer side of the right end of the shaft via a second pulley assembly.
[0024] Compared with existing technologies, the beneficial effects of this invention are as follows: This wind-suction plant protection device with secondary natural enemy screening function adopts advanced spectral technology, which can attract and distinguish pests and their natural enemies. By using different spectra to attract specific insects, and using a high-precision camera to photograph and identify the captured insects, this method can not only accurately calculate the proportion of pests among all insects, but also automatically activate the electric grid pest control system when a preset threshold is reached. This intelligent control greatly reduces manual intervention and improves the efficiency and accuracy of pest management. The specific details are as follows:
[0025] The LED lights in the two pipes emit light of different wavelengths, and together with the suction generated by the rotation of the first fan, they can suck pests and natural enemies into the pest storage area and the natural enemy temporary storage area respectively. The pipes use a reverse suction method to trap pests, which greatly reduces the escape rate of pests. In the light source pipe for natural enemies, a downwind method is used to prevent natural enemies from entering, thereby reducing the accidental trapping rate.
[0026] Furthermore, a second fan forces the insects in the pest chamber into the insect collection tray. A camera then takes a picture, and the captured images are identified. The proportion of pests R in the pest control chamber is calculated by taking i photos at a time, identifying the pests, and averaging the results. The calculation formula is as follows: In the formula, Ai represents the number of pests in the i-th photo; Ni represents the total number of insects in the i-th photo.
[0027] 2. When insects in the pest storage area continuously come into contact with the electric grid and are killed, after T2 minutes, the fan and electric grid are turned off, and the second motor drives the shaft to rotate, which in turn drives the first movable plate to rotate, thereby dumping the dead insects to the outside. At this time, the second movable plate will not rotate.
[0028] Furthermore, if the ratio is less than a certain set ratio R1, the camera and the second fan are turned off, the first movable plate is flipped to release the insects in the pest storage area back into nature, and the insects in the pest chamber are collected again. After working for T3 minutes, all light sources and fans, as well as the electric grid and the top camera in the pest storage area, are turned off. The second motor drives the shaft to reverse. At this time, the shaft uses the ratchet assembly to drive the second movable plate to rotate, which can release the natural enemies in the natural enemy temporary storage area.
[0029] 3. When the first movable plate rotates, the scraper moves along the horizontal direction of the first movable plate under the action of gravity, thereby cleaning away the insect corpses stuck to the first movable plate;
[0030] 4. When the second motor drives the shaft to rotate, the shaft drives the transmission rod to rotate synchronously through the second pulley assembly, causing the cam to rotate and press the bonding block, which in turn causes the bonding block to move the electric grid upward. Then, when the cam stops pressing the bonding block, the electric grid moves downward and resets under the elastic force of the return spring. The above operation is repeated, so the electric grid moves up and down and vibrates, thereby shaking off the insect corpses on the surface of the electric grid and preventing the electric grid from being blocked by insect corpses.

[0041] 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.
[0042] Please see Figures 1-9 The present invention provides the following technical solution: a wind-suction plant protection device with a secondary natural enemy screening function;
[0043] Example 1: To address the problem that existing technologies use a single LED light source to attract insects with different spectra and trap them by suction, achieving high insect trapping efficiency, but even with a specific spectrum, some natural enemies are still attracted or mistakenly killed, and the device does not process the captured natural enemies, resulting in some harm to them, and it does not operate based on the image recognition results; the image capture is merely a snapshot and does not screen pests and natural enemies to reduce the false kill rate, the following solution is disclosed. Please refer to the details. Figures 1-5 and Figure 9 As shown, it includes a bracket 1, and a control box 2 and an insect collection tray 3 are bolted to the upper front of the bracket 1. Channels 4 are fixedly connected to both the left and right sides of the insect collection tray 3.
[0044] It also includes: LED lights 5 installed on the inner walls of both channels 4, with the left LED light 5 having a wavelength of 450 nm and the right LED light 5 having a wavelength of 385 nm, capable of attracting pests and natural enemies respectively; a first fan 6 is rotatably connected to the upper part of the interior of both channels 4 via a shaft; a first motor is bolted to the top of the left channel 4, and the shaft end of the left first fan 6 is fixedly connected to the output end of the first motor; the outer sides of the shaft ends of the two first fans 6 are connected by a first pulley assembly; both channels 4 are connected to the interior of the insect collection tray 3 via connecting pipes; a partition plate 25 is fixed in the middle of the interior of the insect collection tray 3; a natural enemy temporary storage area 7 is provided on the left side of the partition plate 25 inside the insect collection tray 3; and a natural enemy temporary storage area 7 is provided on the right side of the partition plate 25 inside the insect collection tray 3. The insect storage area 8 has a second fan 9 and a camera 10 bolted to the upper part of the insect storage area 8, and an electric grid 11 is installed at the lower part of the insect storage area 8. The bottom of the insect collection tray 3 has openings on both the left and right sides, and the inner walls of the two openings are respectively provided with a first movable plate 12 and a second movable plate 13. A second motor is bolted to the lower right side of the insect collection tray 3. The lower bearing inside the insect collection tray 3 is connected to a shaft 14, and the right end of the shaft 14 penetrates the interior of the insect collection tray 3. The right end of the shaft 14 is fixedly connected to the output end of the second motor. A sleeve 17 is sleeved on the outer side of the left end of the shaft 14. The second movable plate 13 is sleeved and fixed on the outer side of the sleeve 17. The first movable plate 12 is sleeved and fixed on the outer side of the shaft 14. A ratchet assembly block 18 is installed between the shaft 14 and the sleeve 17.
[0045] Step 1: LED lights 5 in the two channels 4 emit light of different wavelengths, simultaneously activating the first motor. The first motor drives one first fan 6 to rotate, and the first pulley assembly drives the other first fan 6 to rotate synchronously. The suction generated by the rotation of the two first fans 6 can draw pests and natural enemies through the channels 4 into the pest storage area 8 and the natural enemy temporary storage area 7, respectively. This reverse suction method within the channels 4 significantly reduces the escape rate of pests. Step 2: The second fan 9 presses the insects in the pest storage area 8 downwards. Then, the camera 10 takes pictures, identifies the captured images, and calculates the proportion R of pests in the insecticidal chamber by taking i photos at a time, identifying them, and taking the average value. The calculation formula is as follows: In the formula, Ai represents the number of pests in the i-th photo; Ni represents the total number of insects in the i-th photo. Step 3: When the insects in the pest storage area 8 continuously come into contact with the electric grid 11 and are killed, after T2 minutes, the second motor is started. The second motor drives the shaft 14 to rotate forward, causing the shaft 14 to drive the first movable plate 12 to rotate, thereby dumping the dead insects to the outside and proceeding to step 4. At this time, the second movable plate 13 will not rotate. Step 4: If the ratio is less than a certain set ratio R1, all LED lights 5, the first fan 6, the second fan 9, the electric grid 11, and the camera 10 are turned off. At this time, the second motor drives the shaft 14 to rotate in reverse, causing the shaft 14 to be driven by the ratchet assembly 18. The rotation of the second movable plate 13 releases the natural enemies in the natural enemy storage area 7. More importantly, the device's operating mode has a minimal impact on the environment. It only activates the pest control system when necessary, effectively reducing the impact on non-target insects and natural enemies. This is crucial for maintaining ecological balance and biodiversity. In contrast, traditional chemical control methods often cause widespread environmental pollution and ecosystem damage. In addition to improving the accuracy and environmental friendliness of pest control, this device can also provide valuable information through continuous data collection, supporting agricultural producers in making data-driven decisions. This data helps analyze pest activity trends and cycles, thereby optimizing pest management strategies and improving the scientific nature and efficiency of agricultural production.
[0046] Example 2: Unlike Example 1, this example utilizes the movement of the scraper 16 to remove the insect carcasses adhering to the first movable plate 12. See details... Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, guide seats 15 are fixed on both the left and right sides of the first movable plate 12, and a fitting block 22 is provided between the two guide seats 15. Slider 20 is slidably connected to the inner wall of the two fitting blocks 22, and a scraper 16 is fixedly connected between the two sliders 20. The bottom of the scraper 16 is in contact with the surface of the first movable plate 12. The slider 20 and the groove 19 are both set in a "T" shape.
[0047] When the shaft 14 drives the first movable plate 12 to rotate to a vertical position, the scraper 16 slides in the groove 19 on the guide seat 15 through the slider 20 under the action of gravity, and moves along the horizontal direction of the first movable plate 12, thereby cleaning away the insect corpses stuck on the first movable plate 12.
[0048] Example 3: Unlike Example 2, this example utilizes the combined use of cam 24, contact block 22, and return spring 21 to cause the electric grid 11 to move up and down reciprocally and generate vibration, thereby shaking off the insect corpses on the surface of the electric grid 11 and preventing the electric grid 11 from being blocked by insect corpses. See details... Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, the left and right sides of the electric grid 11 are slidably connected to the inner wall of the insect collecting tray 3. The top two sides of the electric grid 11 are fitted with return springs 21 between them and the inner wall of the insect collecting tray 3. The bottom two sides of the electric grid 11 are fixed with a contact block 22. The insect collecting tray 3 is provided with a transmission rod 23 located below the electric grid 11. The outer side of the transmission rod 23 is fitted with a cam 24. The positions of the contact block 22 and the cam 24 correspond one-to-one. The bottom of the contact block 22 is in contact with the outer side of the cam 24. The right end of the transmission rod 23 passes through the interior of the insect collecting tray 3. The transmission rod 23 and the insect collecting tray 3 are rotatably connected. The right end of the transmission rod 23 is fixedly connected to the output end of the second motor. The transmission rod 23 and the outer side of the right end of the shaft 14 are connected by a second pulley assembly.
[0049] When the second motor drives the shaft 14 to rotate, the shaft 14 drives the transmission rod 23 to rotate synchronously through the second pulley assembly, causing the cam 24 to rotate and press the bonding block 22, which in turn causes the bonding block 22 to move the electric grid 11 upward. Then, when the cam 24 stops pressing the bonding block 22, the electric grid 11 moves downward and resets under the elastic force of the return spring 21. The above operation is repeated, so the electric grid 11 moves up and down and vibrates, thereby shaking off the insect corpses on the surface of the electric grid 11 and preventing the electric grid 11 from being blocked by insect corpses.
[0050] 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.
