Description

Technical Field

[0001] This utility model relates to the field of pest and disease control technology, specifically to a biological control device for industrial hemp pests and diseases. Background Technology

[0002] Industrial hemp refers to the original plant of the Cannabis genus with a tetrahydrocannabinol (THC) content of less than 0.3% (dry matter weight percentage) and its extracted products. It has a wide range of applications, including textiles, papermaking, food, medicine, daily chemicals, and construction. During cultivation, industrial hemp is susceptible to various pests and diseases, which can affect its growth and development, leading to a significant decrease in fiber and seed yield and quality. Therefore, effective pest and disease control is crucial for ensuring stable and high yields of industrial hemp. Biological control, as an environmentally friendly, quality-assured, sustainable method that is less prone to developing resistance, plays a vital role in the control of pests and diseases in industrial hemp.

[0003] Utility model patent CN201920605487.4 discloses a tobacco moth trap, which includes a trap cage with an inlet on its side for moths to fly into it. A pest collection bag is attached to the bottom opening of the trap cage, and a pheromone is placed inside the trap cage. A flight-blocking spike is installed inside the bottom opening of the trap cage, with one end connected to the inner wall of the trap cage and the other end extending downwards and to the opposite side. The flight-blocking spike is designed not to prevent moths from entering the pest collection bag from the top of the trap cage, but to prevent moths from flying from the collection bag to the top of the trap cage. A light is installed below the flight-blocking spike to attract moths into the pest collection bag. 1. The trap effectively utilizes the phototaxis, color attraction, and pheromone attraction of moths, integrating light attraction, color attraction, and pheromone attraction to improve the trapping efficiency of moth pests. 2. The lure placement rod allows for quick installation and replacement of the lure without unscrewing the trap cage. 3. The anti-fly spikes effectively prevent trapped moth pests from escaping, increasing the trapping success rate.

[0004] Although this tobacco moth trap improves the success rate of trapping, the device still has the following problems in practical use: The device uses a method of directly placing the pheromone inside through a lure placement rod. This design reveals the drawback of reduced pheromone volatilization efficiency in low outdoor temperatures. Because low temperatures slow down the release rate of the pheromone, it weakens its attraction to tobacco moths, affecting the overall trapping effect. Therefore, we propose a biological control device for industrial hemp pests and diseases. Utility Model Content

[0005] To address the aforementioned challenges, this invention provides a biological control device for industrial hemp pests and diseases.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A biological control device for industrial hemp pests and diseases includes a hollow shell with multiple notches on the upper part of the outer wall of the shell, in which multiple electric rods are fixed; a through hole is opened at the bottom of the shell, and fixed seats are fixed on both the left and right sides of the through hole at the bottom of the shell. A sliding groove is opened on the fixed seat, and a slider is slidably installed in the sliding groove. A connecting rod is coaxially fixed at the slider, and the two ends of the connecting rod pass through the fixed seat. A spring is sleeved on the outside of the connecting rod to press against the slider.

[0008] A trapping unit is installed at the through hole. The trapping unit includes a base. Two fixing holes are opened on the outer wall of the base. One end of the connecting rod is inserted into the corresponding fixing hole. Two guide rods are fixed on the top of the base and pass through the interior of the shell. A support rod is coaxially fixed at the center of the top of the base. The support rod passes through the through hole. A tray is coaxially fixed on the top of the support rod. A groove for placing sex attractant is opened on the top of the tray. An electric heating block is fixed at the bottom of the groove.

[0009] Furthermore, a dial is coaxially fixed to one end of the connecting rod away from the fixing hole, and the dial is fixedly connected to the connecting rod by bolts.

[0010] Furthermore, a limiting block is coaxially fixed to the top end of the guide rod, and the diameter of the guide rod is smaller than the diameter of the limiting block.

[0011] Furthermore, the overall shape of the shell is cylindrical, and the shell is made of plastic.

[0012] Furthermore, a rainproof top is provided on the upper part of the housing, and the cross-sectional shape of the rainproof top is conical.

[0013] Furthermore, multiple support rods are installed between the housing and the rainproof roof, and the support rods are fixedly connected to the rainproof roof and the housing by bolts.

[0014] Furthermore, the top of the rainproof roof is fixedly connected to a hanging ring by bolts, and the overall shape of the hanging ring is ring-shaped.

[0015] Furthermore, the cross-sectional shape of the through hole is circular, and the diameter of the through hole is larger than the diameter of the tray and smaller than the diameter of the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The trapping mechanism and casing utilize a specially designed groove to hold the pheromone, which is then heated by an electric heating block. As the pheromone is heated, its release rate and volatilization efficiency significantly increase, effectively enhancing its attraction to pests in industrial hemp cultivation areas and drawing them closer to the casing. Once the pests touch the electrified rod, they are immediately electrocuted and die. This design not only ensures a strong attraction to tobacco moth pests but also improves overall trapping efficiency, providing a strong guarantee for the healthy growth of industrial hemp.

[0018] 2. The design incorporates a fixed base and connecting rods, which facilitates stable installation of the trapping unit, ensuring its stable use. It also allows the tray to easily detach from the housing, making it convenient to place pheromones. This design enhances ease of use. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment provides a technical solution:

[0029] Please see Figures 1-4 As shown, the biological control device for industrial hemp pests and diseases includes a hollow shell 1. Multiple notches 10 are formed at the top of the outer wall of the shell 1, and multiple power rods 11 are fixed within the notches 10. A through hole 17 is formed at the bottom of the shell 1. Fixing seats 12 are fixed on both the left and right sides of the through hole 17 at the bottom of the shell 1. A sliding groove 120 is formed on the fixing seat 12, and a slider 13 is slidably installed within the sliding groove 120. A connecting rod 14 is coaxially fixed to the slider 13, with both ends of the connecting rod 14 passing through the fixing seat 12. A spring 1 is sleeved on the outside of the connecting rod 14 to press against the slider 13. 5; A trapping part 3 is installed at the through hole 17. The trapping part 3 includes a base 30. Two fixing holes 300 are opened on the outer wall of the base 30. One end of the connecting rod 14 is inserted into the corresponding fixing hole 300. Two guide rods 34 are fixed on the top of the base 30. The guide rods 34 pass into the interior of the housing 1. A support rod 31 is coaxially fixed at the center of the top of the base 30. The support rod 31 passes through the through hole 17. A tray 32 is coaxially fixed on the top of the support rod 31. A groove 320 for placing sex attractants is opened on the top of the tray 32. An electric heating block 33 is fixed at the bottom of the groove 320.

[0030] In this embodiment, a dial 16 is coaxially fixed to one end of the connecting rod 14 away from the fixing hole 300. The dial 16 is fixedly connected to the connecting rod 14 by bolts. The dial 16 facilitates pulling the connecting rod 14, while the bolt fixing method facilitates pulling the connecting rod 14.

[0031] In this embodiment, a limiting block 35 is coaxially fixed to the top end of the guide rod 34, and the diameter of the guide rod 34 is smaller than the diameter of the limiting block 35. This design can effectively prevent the guide rod 34 from moving excessively and detaching from the housing 1 during use, thereby avoiding the falling of the trapping part 3 and improving the safety and stability of the entire device.

[0032] In this embodiment, the overall shape of the housing 1 is cylindrical, and the housing 1 is made of plastic. The cylindrical design makes the device more concise and aesthetically pleasing. At the same time, the housing 1 is made of plastic, which has the advantages of being lightweight, corrosion-resistant, easy to process, and insulating, reducing production costs and improving the safety of the device.

[0033] In this embodiment, a rainproof roof 2 is provided on the top of the housing 1, and the cross-sectional shape of the rainproof roof 2 is conical. This design can effectively prevent rainwater from entering the interior of the housing 1, protecting the internal components from damage. At the same time, the conical rainproof roof 2 can also better guide rainwater to the ground, avoiding water accumulation.

[0034] In this embodiment, multiple support rods 20 are installed between the housing 1 and the rainproof roof 2, and the support rods 20 are fixedly connected to the rainproof roof 2 and the housing 1 by bolts. This design enhances the connection strength between the rainproof roof 2 and the housing 1 and improves the stability of the entire device.

[0035] In this embodiment, a hanging ring 21 is bolted to the top of the rainproof roof 2. The hanging ring 21 is ring-shaped. This design allows users to easily suspend and fix the device using the hanging ring 21.

[0036] In this embodiment, the cross-sectional shape of the through hole 17 is circular, and the diameter of the through hole 17 is larger than the diameter of the tray 32 and smaller than the diameter of the base 30. This design ensures that the tray 32 can move smoothly through the through hole 17, while preventing the base 30 from entering the housing 1 through the through hole 17, thus ensuring the safety and stability of the entire device during use.

[0037] It should be added that sex pheromones are highly specific chemical communication substances secreted by insects. They are transmitted through the air and trigger directional behavioral responses in individuals of the same species but different sexes. The main components are C10-C20 long-chain unsaturated compounds. In the control of flue-cured tobacco pests, sex pheromones can specifically attract and trap lepidopteran pests such as tobacco budworms and cotton bollworms. According to thermodynamic effects, especially under constant temperature heating conditions of 25°C, the effective diffusion radius of sex pheromones can be extended from 3-5 meters in the natural state to 8-12 meters. Therefore, heating sex pheromones improves their trapping effect.

[0038] In practical use, the user first connects the power supply to the heating block 33. The heating block 33 starts to work and heats up the pheromone. As the pheromone is heated, its release rate and volatilization efficiency increase. The tobacco moth pests are attracted by the pheromone and approach the shell. When they come into contact with the electric rod 11, they will be electrocuted and die, thus eliminating the tobacco moth pests.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
