Description

Technical Field

[0001] This invention relates to the field of pest and disease control technology, and in particular to an intelligent pest and disease control device and method for forestry planting and seedling cultivation. Background Technology

[0002] The intelligent pest and disease control device for forestry planting and seedling cultivation is a comprehensive system that integrates Internet of Things sensing, image recognition and automated control technologies. It collects environmental and biological data in real time by deploying high-definition cameras, temperature and humidity sensors and insect infestation sensors in the nursery. It uses built-in AI algorithms to accurately identify the types and severity of pests and diseases and automatically triggers corresponding physical trapping, precise spraying or biological control mechanisms. This reduces the use of chemical pesticides while achieving efficient, early intervention and scientific control of seedling diseases.

[0003] Current forestry planting and seedling cultivation methods mainly rely on pesticide spraying for pest and disease control, which may miss some areas. Alternatively, trapping lamps are installed throughout the cultivation room, typically using ultraviolet light or odor to attract pests. For example, a pest and disease control structure for fruit tree seedling cultivation disclosed in patent application CN224522160U includes a cultivation bed with several cultivation troughs on its top. A covering spray assembly is attached to the top of the cultivation bed, and combined trapping components are installed on both sides, front, and back of the cultivation bed. Each combined trapping component includes a connecting block, which is attached to the cultivation bed on the side closest to it, and a support rod is attached to the top of the connecting block. This addresses the problem that most existing pest and disease control structures rely on manual, mobile pesticide spraying, which is difficult to operate and may result in incomplete spraying. Furthermore, the reliance on pesticide spraying leads to pesticide residues, harming the ecological environment and human health, and potentially causing pesticide resistance in pests.

[0004] The drawback is that when staff and traps are in the same room, pests often prefer to target people rather than lights. When staff approach the seedlings, pests also approach the seedlings and may attach themselves to them, causing damage. Therefore, this invention aims to solve the above problems. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] This invention provides an intelligent pest and disease control device and method for forestry planting and seedling cultivation, which can solve the problem that existing methods cannot completely isolate pests and diseases. The specific solution is as follows: On one hand, the present invention provides an intelligent pest and disease control device for forestry planting and seedling cultivation, including a trapping net covering the top of the seedling nursery. The trapping net covers the cultivation boxes inside the seedling nursery, so that the seedlings inside the cultivation boxes are located inside the trapping net. The aperture of the trapping net is large enough to block pests and diseases outside the trapping net. The top of the trapping net has a trapping roller with sliders rotatably mounted at both ends of the trapping roller. Trapping lights are mounted at both ends of the trapping roller. The sliders are slidably connected to the outer wall of the trapping net. A driving device is mounted on the slider at one end of the trapping roller, which drives the trapping roller to rotate. The trapping roller is filled with insecticidal powder. The outer wall of the trapping roller has fine holes. When the trapping roller rotates, the insecticidal powder can flow out from the fine holes and fall onto the trapping net.

[0007] Preferably, the trapping net is woven from metal wire, and the lower part of the trapping net is supported by a rigid material, so that the trapping net forms a cover that can cover the cultivation box.

[0008] Preferably, the inner diameter of the fine pores is 2-5 times the diameter of a single insecticidal powder particle. When the trapping roller is stationary, the static friction, arching effect, and cohesive force between the particles of the insecticidal powder work together to form a stable mechanical structure that is sufficient to resist gravity, thus ensuring that the insecticidal powder remains inside the trapping roller and does not leak out.

[0009] Preferably, the end of the trapping net parallel to the trapping roller is hinged to the end of the seedling device. The trapping net and the trapping roller can be folded to be parallel to each other. Several ventilation holes are opened on the side of the trapping net. The ventilation holes on both sides of the trapping net can form convection, so that the air inside the seedling device can circulate and ensure the normal growth of the seedlings.

[0010] Preferably, the seedling device has several slots inside, the shape of the cultivation box matches the shape of the slots, the cultivation box is inserted into the slots, and the bottom of the cultivation box has water-permeable holes. Several visual sensors are installed on the seedling device, which can identify the image of the trapping net above it and determine whether the trapping net is covered by pests and diseases and the area covered.

[0011] Preferably, a slide rail is fixed to the side of the trap net, the bottom of the slider is slidably connected to the slide rail, and several brushes are fixed to the outer wall of the trap roller. The brushes are distributed in a spiral shape on the outer wall of the trap roller, and the spiral brushes have several rows.

[0012] Preferably, a rack is fixed to the outer wall of the trapping net, the rack extends along the sliding direction of the slider, and a drive gear is fixed to the end of the trapping roller away from the drive device. The drive gear and the rack mesh with each other through a reversing gear, and the reversing gear is rotatably mounted on the outer wall of the slider.

[0013] Preferably, when the drive device drives the trapping roller and the drive gear to rotate forward, the reversing gear rotates in reverse and moves on the rack, thereby driving the slider and the trapping roller to slide to one side of the trapping net, so that the trapping roller scrapes the pests on the trapping net in the direction of the trapping roller's movement, thus preventing pests from remaining on the trapping net.

[0014] Preferably, the end of the trapping roller is provided with a feeding chamber, and the top of the slider is provided with a feeding port. The feeding port is connected to the feeding chamber, and a sealing plug is threaded on the feeding port. When insecticidal powder needs to be added, the insecticidal powder enters the trapping roller from the feeding port and the feeding chamber.

[0015] On the other hand, the present invention provides an intelligent pest and disease control method for forestry planting and seedling cultivation, comprising the following steps: S1. Configure the trapping net and cover the top of the seedling incubator with the trapping net so that the trapping net completely wraps the cultivation box inside the seedling incubator, ensuring that the seedlings inside the cultivation box are within the protective space of the trapping net; S2. Use the mesh of the trap net to physically intercept pests and diseases, keeping them outside the trap net and forming the first line of defense against pests and diseases. S3. Install trapping lights at both ends of the trapping roller, turn on the trapping lights, and use the light emitted by the trapping lights to attract phototactic pests that are blocked outside the trapping net to gather on the trapping roller. S4. The trapping roller is driven to rotate around its two ends by a drive device installed on the slider. When the trapping roller rotates, the insecticidal powder pre-loaded inside it is thrown out through the fine holes opened on the outer wall of the trapping roller and evenly sprinkled onto the trapping net below. S5. The trap net with insecticidal powder sprinkled on it forms a second line of defense against pests and diseases. When pests come into contact with or climb onto the surface of the trap net with insecticidal powder, they are killed by contact.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. The trapping net of this invention is woven from metal wire, with a rigid material supporting the lower part to form a cover structure. This completely covers the seedling trays inside the nursery, placing the seedlings in a closed, protected space. Its aperture design effectively blocks external pests and diseases, cutting off their direct path of attack on the seedlings at the source. Combined with the scraping action of the trapping roller and brush, pests attached to the net surface are promptly removed, preventing insect accumulation and clogging of the mesh, maintaining the net's permeability. This structure significantly improves the biosafety of the seedling environment, reduces the frequency of chemical pesticide spraying, aligns with the development concept of green forestry, and is particularly suitable for seedling bases with high ecological requirements.

[0017] 2. This invention pre-fills the trapping roller with insecticidal powder. During rotation, the powder is evenly spread onto the surface of the trapping net through the fine holes in the outer wall of the trapping roller, forming a continuous insecticidal barrier. In a static state, the powder maintains a stable mechanical structure through the synergistic effect of the cohesive force between particles, the arching effect, and static friction, effectively resisting gravity and preventing leakage, thus avoiding pesticide waste and environmental pollution. The rotational release mode allows for flexible adjustment of the dosage according to the severity of pest infestation, ensuring both control effectiveness and control of pesticide intensity. Combined with the light-attracting function of the trapping lamp, it can concentrate on killing phototactic pests at night, significantly improving the overall efficiency of pest and disease control.

[0018] 3. The driving device of this invention rotates the trapping roller while simultaneously driving the slider to move along the slide rail through the meshing of the drive gear, reversing gear, and rack. This causes the trapping roller to reciprocate and scrape the surface of the trapping net. This linkage mechanism transforms rotational motion into linear cleaning motion. The spiral brush blades thoroughly wipe the net surface during movement, concentrating and pushing insect carcasses and residual eggs in a designated direction, preventing localized accumulation that could affect the mesh's air permeability. The mobile cleaning structure reduces the frequency of manual maintenance, improves the automation level of the device, and is particularly suitable for the continuous operation needs of large-scale forestry seedling bases, effectively reducing the labor intensity of management personnel.

[0019] 4. The trapping net of this invention is hinged at one end to the end of the seedling incubator, and can be folded to a parallel position with the seedling incubator, facilitating the removal, replacement, and daily inspection of the incubator boxes, significantly improving operational convenience. Ventilation holes on the sides of the trapping net create convection channels on both sides, ensuring continuous air circulation inside the seedling incubator and maintaining a suitable temperature and humidity environment for seedling growth. The folding design significantly reduces the space occupied when not in operation, facilitating equipment transportation, storage, and deployment. The optimized hinge structure ensures positional accuracy and sealing performance after multiple opening and closing operations, extending the overall service life of the machine and adapting to the working conditions of field forestry operations.

[0020] 5. The visual sensors installed on the seedling generator of this invention can collect real-time images of the surface condition of the trapping net, automatically identify changes in the coverage area and density of pests and diseases, and provide quantitative basis for prevention and control decisions. This system replaces the traditional manual inspection method, significantly reducing the workload of patrols, and can automatically trigger the operation of the trapping roller or the release of insecticide powder based on the identification results, achieving precise and on-demand pest and disease control. Combined with the light attraction mechanism of the trapping lamp and the mechanical scraping cleaning function, the entire system can operate continuously and stably under unattended conditions, greatly shortening the response cycle of pest and disease control, improving the reliability of control, and meeting the management needs of modern smart forestry.

Detailed Implementation

[0024] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0025] Example 1: As Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides an intelligent pest and disease control device for forestry planting and seedling cultivation, including a trap net 1. The trap net 1 is made of woven metal wire and covers the top of the seedling device 2. The trap net 1 can cover the cultivation box 3 inside the seedling device 2. The lower part of the trap net 1 is supported by a rigid material, so that the trap net 1 forms a cover that can cover the cultivation box 3, so that the seedlings inside the cultivation box 3 are located inside the trap net 1. The aperture of the trap net 1 can block pests and diseases outside the trap net 1. The top of the trap net 1 has a trap roller 4. Several brushes 5 are fixed to the outer wall of the trap roller 4. The brushes 5 are spirally distributed on the outer wall of the trap roller 4, and the spiral brushes 5 have several rows. Trapping lights 8 are installed at both ends of the trap roller 4.

[0026] It should be noted that the trapping lamp 8 utilizes the phototaxis, wavetaxis, and colortaxis of insects. At night, it ignites a specific spectrum (such as a wide band of 320~680nm or a narrow band of 365 / 420nm) of LED or black light source to simulate the visual sensitivity peak of pests, inducing them to fly towards the light source like "moths to a flame".

[0027] like Figure 4 As shown, sliders 6 are rotatably mounted at both ends of the trapping roller 4, and slide rails 7 are fixedly connected to the side of the trapping net 1. The bottom of the sliders 6 is slidably connected to the slide rails 7. A drive device 9 is mounted on the slider 6 at one end of the trapping roller 4. The drive device 9 can be a motor. The trapping roller 4 is rotated by the drive device 9. The trapping roller 4 is filled with insecticidal powder. The outer wall of the trapping roller 4 has fine holes (not shown in the figure). When the trapping roller 4 rotates, the insecticidal powder can flow out from the fine holes and fall onto the trapping net 1.

[0028] It should be noted that the inner diameter of the fine holes is 2-5 times the diameter of a single insecticidal powder. When the trapping roller is stationary, the static friction, arching effect, and cohesive force between the particles of the insecticidal powder work together to form a stable mechanical structure that is sufficient to resist gravity, thus keeping the insecticidal powder inside the trapping roller and preventing it from leaking out.

[0029] like Figure 5 , Figure 6 As shown, the end of the trapping roller 4 is provided with a feeding chamber 10, and the top of the slider 6 is provided with a feeding port 11. The feeding port 11 is connected to the feeding chamber 10. A sealing plug 12 is also threaded on the feeding port 11. When insecticidal powder needs to be added, the insecticidal powder enters the trapping roller 4 from the feeding port 11 and the feeding chamber 10.

[0030] like Figure 1 , Figure 7 , Figure 8As shown, the end of the trapping net 1 parallel to the trapping roller 4 is hinged to the end of the seedling device 2. The trapping net 1 and the trapping roller 4 can be folded to be parallel to each other. Several ventilation holes 13 are opened on the side of the trapping net 1. The several ventilation holes 13 on both sides of the trapping net 1 can form convection, so that the air in the seedling device 2 can circulate and ensure the normal growth of the seedlings.

[0031] like Figure 8 As shown, the seedling device 2 has several slots 14 inside. The shape of the cultivation box 3 matches the shape of the slot 14. The cultivation box 3 is inserted into the slot, and the bottom of the cultivation box 3 has water-permeable holes. Several vision sensors 15 are installed on the seedling device 2. The vision sensors 15 can identify the image of the trap net 1 above it, determine whether the trap net 1 is covered by pests and diseases, and calculate the covered area.

[0032] like Figure 6 , Figure 9 , Figure 10 As shown, a rack 16 is fixed to the outer wall of the trap net 1. The rack 16 extends along the sliding direction of the slider 6. A drive gear 17 is fixed to the end of the trap roller 4 away from the drive device 9. The drive gear 17 and the rack 16 mesh with each other through a reversing gear 18. The reversing gear 18 is rotatably mounted on the outer wall of the slider 6.

[0033] In the above scheme, such as Figure 9 As shown by the dashed arrow, when the drive device 9 drives the trapping roller 4 and the drive gear 17 to rotate forward, the reversing gear 18 rotates in reverse and moves on the rack 16, thereby driving the slider 6 and the trapping roller 4 to slide to one side of the trapping net 1. This allows the trapping roller to scrape the pests on the trapping net 1 in the direction of the trapping roller 4's movement, thus preventing pests from remaining on the trapping net 1.

[0034] Example 2: This example differs from Example 1 in that it provides an intelligent pest and disease control method for forestry planting and seedling cultivation, comprising the following steps: S1. Attraction Stage: At night or in low-light conditions, the trapping lamp 8 emits a specific spectrum of light, attracting surrounding pests to the area where the trapping net 1 is located, based on the physiological characteristics of insects' phototaxis, wave-taxis, and color-taxis. During their phototaxis flight, the pests are physically blocked outside the trapping net 1, preventing them from penetrating the mesh and entering the seedling device 2 to harm the seedlings, thus achieving the first line of physical defense.

[0035] S2. Application Stage: After the drive device 9 is started, it drives the trapping roller 4 to rotate forward. The insecticidal powder stored inside the trapping roller 4 is evenly sprinkled onto the surface of the trapping net 1 through the fine pores of the outer wall under the action of centrifugal force, forming an insecticidal film. Pests that come into contact with this film will die from poisoning by the agent. In a static state, the powder is kept stable by the composite mechanical structure formed by the cohesive force between particles, the arching effect and static friction, and does not leak, ensuring the controlled release and long-term storage of the agent.

[0036] S3. Cleaning Stage: When the trapping roller 4 rotates, the drive gear 17 at its end rotates synchronously. This gear, via the reversing gear 18, meshes with the rack 16 fixed to the outer wall of the trapping net 1, driving the slider 6 to translate along the slide rail 7. This translation causes the trapping roller 4 to move laterally across the surface of the trapping net 1. The spirally distributed brushes 5 continuously scrape the net surface during this movement, pushing dead insects, eggs, and residual powder to one side to prevent localized accumulation and blockage of the ventilation holes 13. The forward and reverse switching of the drive device 9 enables the reciprocating motion of the trapping roller 4, ensuring thorough cleaning of the net surface.

[0037] S4. Monitoring: The visual sensor 15 continuously collects image information from the surface of the trap net 1, and analyzes the pest coverage area and density through image recognition algorithms. When the detection value exceeds the preset threshold, the control system automatically activates the drive device 9 and the trap light 8 to start a new round of trapping-application-cleaning cycle; when the coverage area is low, the system remains in standby mode to save energy and pesticides, realizing an intelligent operation mode of on-demand prevention and control.

[0038] S5. Maintenance: When insecticide powder needs to be replenished, the operator unscrews the sealing plug 12 and adds powder into the trapping roller 4 through the feed inlet 11 and feed chamber 10. During routine maintenance, the trapping net 1 can be folded around the hinge shaft to a position parallel to the seedling device 2, facilitating the removal, replacement, and inspection of the cultivation box 3. The ventilation holes 13 form air convection channels on both sides of the trapping net, ensuring oxygen supply and heat and humidity exchange inside the seedling device 2, providing a stable microenvironment for seedling growth. Through the organic integration of the above steps, the entire device achieves fully automated and intelligent operation of forestry seedling pest and disease control.

[0039] In summary, the trapping net 1 of this invention is made of woven metal wire, with a rigid material supporting the lower part to form a cover structure. This completely covers the cultivation box 3 inside the seedling tray 2, placing the seedlings in a closed, protected space. Its aperture design effectively blocks external pests and diseases, cutting off their direct path of attack on the seedlings at the source. Combined with the scraping action of the trapping roller 4 and brush 5, pests attached to the net surface can be removed promptly, preventing insect accumulation and clogging of the mesh, maintaining the net's permeability. This structure significantly improves the biosafety of the seedling environment, reduces the frequency of chemical pesticide spraying, and aligns with the development concept of green forestry. It is particularly suitable for seedling bases with high ecological requirements. This invention pre-places insecticidal powder inside the trapping roller 4. During rotation, the powder is evenly distributed onto the surface of the trapping net 1 through the fine pores on the outer wall of the trapping roller 4, forming a continuous insecticidal barrier. In a static state, the powder relies on the synergistic effect of interparticle cohesion, arching effect, and static friction. The stable mechanical structure effectively resists gravity and prevents leakage, avoiding pesticide waste and environmental pollution. The rotating release mode allows for flexible adjustment of the dosage according to the severity of pest infestation, ensuring both control effectiveness and intensity. Combined with the light-attracting function of the trapping lamp 8, it enables concentrated killing of phototactic pests at night, significantly improving overall pest control efficiency. Simultaneously, the drive device 9 rotates the trapping roller 4, and through the meshing transmission of the drive gear 17, reversing gear 18, and rack 16, it drives the slider 6 to move along the slide rail 7, causing the trapping roller 4 to reciprocate and scrape the surface of the trapping net 1. This linkage mechanism converts rotational motion into linear cleaning motion. The spiral brush 5 thoroughly wipes the net surface during movement, concentrating and pushing insect carcasses and residual eggs in a designated direction, preventing localized accumulation that could affect the mesh's breathability. The mobile cleaning structure reduces the frequency of manual maintenance and improves the level of automation of the device, making it particularly suitable for the continuous operation needs of large-scale forestry seedling bases. It effectively reduces the labor intensity of management personnel. One end of the trapping net 1 is hinged to the end of the seedling device 2, allowing it to be folded parallel to the seedling device, facilitating the removal, replacement, and daily inspection of the cultivation boxes 3, significantly improving operational convenience. The ventilation holes 13 on the sides of the trapping net form convection channels on both sides, ensuring continuous air circulation inside the seedling device 2 and maintaining a suitable temperature and humidity environment for seedling growth. The folding design significantly reduces the space occupied when not in operation, facilitating the transportation, storage, and deployment of the equipment.The articulated structure is optimized to ensure positional accuracy and sealing performance after multiple opening and closing cycles, extending the overall service life of the machine and adapting to the working conditions of field forestry operations. The visual sensor 15 installed on the seedling device 2 of this invention can collect real-time images of the surface condition of the trapping net 1, automatically identify the coverage area and density changes of pests and diseases, and provide quantitative basis for prevention and control decisions. This system replaces the traditional manual inspection method, significantly reducing the workload of patrols, and can automatically trigger the operation of the trapping roller 4 or the release of insecticide powder based on the identification results, achieving precise and on-demand pest and disease control. Combined with the light attraction mechanism of the trapping lamp 8 and the mechanical scraping cleaning function, the entire system can operate continuously and stably under unattended conditions, greatly shortening the response cycle of pest and disease control, improving the reliability of control, and meeting the management needs of modern smart forestry.
