Description

Technical Field

[0001] The present invention relates to the technical field of garden plant protection, and in particular to a garden plant physical insecticide circulation system based on integrated light-induced biodegradation. Background Art

[0002] In order to eliminate pests that harm garden plants in a timely manner, prevent pests from eating leaves, stems, flowers and fruits of plants, ensure the normal growth and development of plants, enhance the resistance of plants to stress, reduce plant diseases caused by pests, and maintain the health of plants, it is often necessary to place insecticide equipment in the garden.

[0003] Existing physical insecticide technologies mostly include light-trapping and mechanical trapping. Light-trapping uses the insect's phototaxis to attract pests to high-voltage power grids or sticky insect boards for killing through light sources of specific wavelengths. However, there are problems with the accumulation of insect corpses that require manual cleaning and the easy breeding of secondary pollution. Mechanical trapping, such as vibrating insect sticky traps and insect suckers, is inefficient and cannot process insect bodies. Traditional physical insecticide technology does not solve the problem of insect body recycling. If insect corpses are discarded at will, they may spread pathogens or pollute the environment, while chemical decomposition methods are costly and damage the ecology. Summary of the Invention

[0004] Technical problems solved In view of the above shortcomings of the existing technology, the present invention provides a garden plant physical insecticide circulation system based on integrated light-induced biodegradation, which can effectively solve the problem of the existing technology of combining physical insecticide with harmlessness and resource utilization of insect bodies.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: The present invention provides a garden plant physical insecticide circulation system based on integrated light-induced biodegradation, comprising: The insect attracting device is divided into two parts, the upper part of the insect attracting device is arranged from the inside to the outside, and is used to attract and kill insects. The electric grid is set separately. The bottom end of the light source is fixedly connected to an upper limit frame for limiting the top end of the electric grid. The bottom end of the light source is fixedly connected to a lower limit plate for limiting the bottom end of the electric grid. The insect attracting device in the lower part includes a collecting part for collecting insect bodies; Biodegradation equipment; nutrient supply equipment; Wherein, the collecting part includes a threaded rod for preliminary crushing of the insect body.

[0006] Furthermore, the upper and lower ends of the power grid are fixedly connected with fixed plates, and the other end of the fixed plate is provided with a vibration plate.

[0007] Furthermore, a limiting groove 1 is symmetrically provided inside the upper limit frame, and the inner wall of the limiting groove 1 is slidably connected to the outer wall of the fixing plate.

[0008] Furthermore, a guide block is fixedly connected to the middle of the top end of the lower limit plate. The guide block adopts a conical design that is narrow at the top and wide at the bottom. A second limit groove is provided on the periphery of the guide block.

[0009] Furthermore, the collecting member further comprises a funnel arranged on the periphery of the threaded rod, the periphery of the funnel is rotatably connected to a fixing frame, and the threaded rod, the funnel and the fixing frame are arranged in sequence from the inside to the outside.

[0010] Furthermore, the top end of the threaded rod is rotatably connected to the bottom end of the guide block.

[0011] Furthermore, the inner wall of the funnel is provided with a threaded plate that cooperates with the threaded rod, the top of the funnel is fixedly connected to a guide plate, and the outer wall of the guide plate is evenly fixed with bumps.

[0012] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The present invention is provided with a lower limit plate. The insect bodies on the outer wall of the power grid slide down along the edge of the guide plate and the inclined surface of the guide block. The insect bodies enter the interior of the collecting piece under the action of gravity. The threaded rod and the threaded plate move relative to each other. The insect bodies enter the threaded channels of the threaded rod and the threaded plate. The insect bodies are further crushed and then enter the next step, realizing a green prevention and control system for resource utilization of insect bodies, integrating light-induced killing, insect body biodegradation and intelligent nutrient supply technology.

[0013] The present invention is provided with a protrusion, the top end of the protrusion contacts the vibration plate at the bottom end. As the guide plate rotates, the top end of the protrusion applies intermittent force to the vibration plate. Under the action of the vibration plate, the fixed plate moves back and forth under the restriction of the second limit groove and the first limit groove. The split-designed power grid vibrates back and forth up and down in turn under the restriction of the second limit groove and the first limit groove. The carbonized insect body may adhere to the surface of the power grid due to the high temperature, and the up and down vibrating power grid can remove the carbonized insect body.

[0017] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] The present invention will be further described below with reference to the embodiments. Example

[0019] See also Figure 1-Figure 7 The present invention provides a technical solution for a garden plant physical insecticide circulation system based on integrated light-induced biodegradation: refer to Figure 1 and Figure 2 The device includes an insect attractant 1, a biodegradation device 2, and a nutrient supply device 3. The insect attractant 1 is divided into an upper and lower part. The upper part of the insect attractant 1 is configured from the inside to the outside with a light source 11, a power grid 12, and a frame 13, which are used to attract and kill insects. An integrated multispectral imaging sensor (wavelength range 400-1000nm) is set outside the light source 11. A convolutional neural network (CNN) is used to classify pest species in real time and dynamically match the optimal trapping spectrum (for example, Lepidoptera prefer 365nm, Diptera responds to 520nm), thereby improving trapping accuracy. The power grid 12 uses a low-voltage pulse electric shock module with a voltage of ≤500V, ensuring that the pests are instantly stunned without carbonizing the insect body, preserving the integrity of the insect body to facilitate subsequent degradation. A titanium oxide-based photocatalytic coating (such as a TiO2 / SiO2 composite film) is sprayed on the surface of the power grid 12, and ultraviolet light is used to excite the generation of hydroxyl free radicals to decompose residual organic matter in the insect body, reducing dependence on mechanical vibration.

[0020] The collected insects enter the enclosed fermentation chamber of biodegradation equipment 2 via a screw conveyor. The chamber is divided into three zones: crushing, high-temperature fermentation, and low-temperature maturation. The crushing zone uses a multi-stage insect crushing system, divided from top to bottom into the primary and secondary zones. The primary zone performs shear crushing, with staggered blades (hardness above HRC60) added to the top of the threaded rod. The blade gap is adjustable (0.5-2mm), allowing for adaptive crushing of pests of different sizes. The secondary zone performs ultrasonic cell wall disruption: an ultrasonic generator (frequency 28kHz, power 500W) is installed at the fermentation chamber entrance, using the cavitation effect to destroy the insect cell walls, increasing the efficiency of the degradation bacteria by more than 30%. Thermomyces stearothermophilus is added to the high-temperature fermentation zone (55-60°C) to degrade insect protein and chitin within 48 hours. The low-temperature maturation zone (25-30°C) is inoculated with Trichoderma fungi to synthesize humic acid and water-soluble nitrogen, phosphorus, and potassium.

[0021] An ultrafiltration membrane using liquid fertilizer membrane separation technology is installed at the bottom of the closed fermentation chamber. The fermentation products are separated by the ultrafiltration membrane (pore size 0.1μm). The concentrated liquid is used as high-nitrogen organic fertilizer, and the filtrate containing small molecule amino acids is directly used for foliar spraying.

[0022] The nutrient supply equipment includes a root drip irrigation module, a foliar atomization module, and an IoT collaborative platform. Their functions are as follows: concentrated fertilizer liquid penetrates into the plant rhizosphere through a capillary network, with the flow rate dynamically regulated by a soil EC value sensor; the filtrate is sprayed onto the back of leaves through an ultrasonic atomizer (particle size ≤ 10 μm) to simultaneously prevent and control diseases; a plant-soil-climate multi-parameter model is established, integrating leaf temperature (infrared sensor), transpiration rate (stem flow meter), and meteorological data, and a fuzzy PID controller is used to adjust the EC value of the liquid fertilizer and the spraying frequency.

[0023] refer to Figure 3 、 Figure 4 and Figure 5The power grid 12 is set up in a split manner. The bottom end of the light source 11 is fixedly connected to an upper limit frame 14 for limiting the top end of the power grid 12. The bottom end of the light source 11 is fixedly connected to a lower limit plate 15 for limiting the bottom end of the power grid 12. The middle part of the top of the lower limit plate 15 is fixedly connected to a guide block 152. The guide block 152 adopts a conical design with a narrow top and a wide bottom. A limiting groove 2 151 is arranged on the periphery of the guide block 152. The upper and lower ends of the power grid 12 are fixedly connected to a fixed plate 121. A vibration piece 122 is arranged at the other end of the fixed plate 121. A limiting groove 141 is symmetrically arranged inside the upper limit frame 14. The inner wall of the limiting groove 141 is slidably connected to the outer wall of the fixed plate 121.

[0024] refer to Figure 1 、 Figure 6 and Figure 7 The lower part of the insect trapping device 1 includes a collecting part 16 for collecting insects. A microwave generator (2.45 GHz, adjustable power) is integrated at the bottom of the collecting part 16. The insects are irradiated for 30 seconds during their fall (the temperature rises to 75°C), inactivating insect eggs and pathogens (such as the survival rate of Beauveria bassiana spores <0.1%). The collecting part 16 is sequentially arranged from the inside to the outside, including a threaded rod 161, a funnel 162, and a fixed frame 163. The collecting part 16 also includes a funnel 162 arranged on the periphery of the threaded rod 161. The periphery of the funnel 162 is rotatably connected to the fixed frame 163. The top of the threaded rod 161 is rotatably connected to the bottom end of the guide block 152. The inner wall of the funnel 162 is provided with a threaded plate 164 that cooperates with the threaded rod 161. The top of the funnel 162 is fixedly connected to a guide plate 165, and the outer wall of the guide plate 165 is evenly fixed with bumps 166.

[0025] A motor is provided at the bottom end of the funnel 162. The funnel 162 rotates relative to the threaded rod 161. There is a spiral path between the threaded plate 164 and the outer wall of the threaded rod 161. A circular groove is provided at the top of the fixed frame 163. A circular plate rotatably connected to the circular groove is provided at the bottom end of the guide plate 165. The funnel 162 rotates under the restriction of the circular groove of the fixed frame 163. The rotation of the funnel 162 drives the guide plate 165 to rotate. The rotation of the guide plate 165 drives the protrusion 166 to rotate. The top of the protrusion 166 contacts the vibration plate 122 at the bottom. As the guide plate 165 rotates, the protrusion 166 is rotated. The top of block 166 applies intermittent force to the vibration plate 122, and the driver of the vibration plate 122 drives it to vibrate at high frequency and micro amplitude. Under the action of the vibration plate 122, the fixed plate 121 moves back and forth under the restriction of the second limit groove 151 and the first limit groove 141. The split-designed power grid 12 vibrates back and forth in turn under the restriction of the second limit groove 151 and the first limit groove 141. The carbonized insect body may adhere to the surface of the power grid 12 due to the high temperature. The high-frequency micro amplitude vibration (20-40kHz) is used to achieve contactless insect corpse separation and reduce mechanical loss.

[0026] The funnel 162 is driven to rotate by the motor, which can provide a stable and controllable power source, so that the funnel 162 rotates according to the set speed and direction, ensuring the stable operation of the entire device.

[0027] The spiral path design between the threaded rod 161 and the threaded plate 164 can convert the rotation of the funnel 162 into the linear motion of the threaded plate 164. This transmission method has high precision and reliability and can achieve more accurate position control.

[0028] The cooperation between the circular groove at the top of the fixed frame 163 and the funnel 162 and the guide plate 165 not only limits the rotation range of the funnel 162 to ensure its stable rotation, but also provides a support and rotation basis for the guide plate 165, making the entire structure more stable.

[0029] The rotation of the guide plate 165 drives the protrusion 166 to rotate, which can transmit the rotation of the funnel 162 to the protrusion 166, so that the protrusion 166 applies a force to the vibration plate 122, realizing effective transmission and conversion of motion.

[0030] After the vibration plate 122 is subjected to the force applied by the protrusion 166, the driver of the vibration plate 122 drives it to vibrate at a high frequency and slightly, and the vibration plate 122 drives the fixed plate 121 to vibrate, so that the fixed plate 121 moves back and forth under the restriction of the limit groove 141 and the limit groove 2 151. A rubber layer is provided on the surface of the vibration plate 122, which cushions the impact force when the vibration plate 122 and the fixed plate 121 vibrate, reduces the wear of the device, and also provides a softer driving force.

[0031] The split-designed power grid 12 vibrates back and forth up and down under the constraints of the limiting groove 141 and the limiting groove 2 151, which helps to remove carbonized insect bodies adhering to the power grid 12 and prevent the accumulation of insect bodies from affecting the performance of the power grid 12. At the same time, the vibration method is relatively mild and will not cause excessive mechanical damage to the power grid 12, which is conducive to extending the service life of the power grid 12.

[0032] The insect bodies on the outer wall of the electric grid 12 slide down along the edge of the guide plate 165 and the inclined surface of the guide block 152. Under the action of gravity, the insect bodies enter the interior of the collecting member 16. The threaded rod 161 and the threaded plate 164 move relative to each other, and the insect bodies enter the threaded path of the threaded rod 161 and the threaded plate 164. The insect bodies are further crushed and then enter the next step.

[0033] The design of the edge of the guide plate 165 and the inclined surface of the guide block 152 can provide a clear sliding path for the insect body, allowing the insect body to enter the collecting member 16 more smoothly along a specific direction, thereby improving the efficiency of insect body collection and reducing the possibility of insect bodies remaining in other parts.

[0034] Guiding the insects to slide down along a specific path prevents the insects from randomly piling up or sliding on the power grid 12 and causing additional friction or collision to the power grid 12 , thereby helping to protect the integrity and performance of the power grid 12 and extend the service life of the power grid 12 .

[0035] After the insect body enters the threaded channel of the threaded rod 161 and the threaded plate 164, it is further crushed. This process can break the insect body into smaller particles, which is conducive to subsequent more in-depth processing of the insect body, such as further analysis, harmless treatment or use as fertilizer, etc., increasing the diversity and practicality of insect body processing.

[0036] Crushing the insect bodies can prevent larger insect bodies or insect body agglomerates from clogging the collecting member 16 or subsequent pipes, processing equipment, etc., thereby ensuring the smooth operation of the entire insect body collection and processing system.

[0037] The crushed insect bodies are easier to clean and disinfect, reducing the possibility of bacteria breeding and odor generation by the insect body residues, and helping to maintain the hygiene of the collecting member 16 and the surrounding environment.

[0038] The present invention is a green pest control system that kills pests through physical means and realizes the resource utilization of insect bodies. It integrates light-induced killing, insect biodegradation and intelligent nutrient supply technologies, and is suitable for scenes such as urban green spaces, parks, and courtyards.

[0039] When conducting tree pest control, three sets of light attractants are arranged in a circle around the tree trunk, the wavelength of the light source is set to 365nm (for adult longhorn beetles), and the electric shock net is 20cm away from the tree trunk; the fermentation chamber automatically adjusts the temperature according to the insect input, and the daily insect processing volume is ≥5kg, and the output liquid fertilizer has a pH value of 6.5-7.0 and a total nitrogen content of ≥4%; the drip irrigation module applies 20L / week to the root zone per tree, and the foliar spray is started at 6:00 in the morning to avoid evaporation due to strong light.

[0040] When controlling underground lawn pests, use 520nm green light to trap and kill adult scarab beetles. The electric shock net is buried 10cm underground. After being killed, the insect bodies are directly introduced into the fermentation chamber. Add Beauveria bassiana spores to enhance fermentation. The number of spores in the produced fertilizer should be ≥1×10 6 CFU / g, combining fertility and sustained insecticidal function.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
