Description

Technical Field

[0001] This utility model relates to the field of pest trapping technology, and in particular to a biodegradable and environmentally friendly pest trapping device. Background Technology

[0002] With the increasing demand for integrated pest management, technological iterations primarily focus on optimizing trapping efficiency. This includes improving the tactic response of target organisms through precise pheromone formulation, spectral wavelength adjustment, or upgraded bait recipes. In practical applications, efficient trapping often results in a large accumulation of target organisms, requiring frequent cleaning of insect remains from the device to maintain its function. For example, Chinese Patent No. CN 221082483 U discloses a pest trapping device that uses an insertion cone to quickly insert into loose soil, accelerating installation efficiency. However, due to its narrow collection chamber and unique installation location (enclosed space), insect removal is time-consuming and labor-intensive. Dead pest remains can easily carry pathogens (such as bacteria and viruses) or parasite eggs, potentially causing cross-infection during cleaning due to direct contact or aerosol inhalation. Furthermore, improper disposal of residues can lead to secondary pollution through the food chain or environmental media. However, while burying the insects and the equipment directly can reduce biosafety risks, the materials left in the soil for a long time can cause environmental problems such as microplastic diffusion and heavy metal leaching, which conflicts with the concept of green pest control. Utility Model Content

[0003] Therefore, it is necessary to provide biodegradable and environmentally friendly pest trapping devices to address the problems of difficult cleaning and easy cross-infection of existing trapping devices.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] The biodegradable and environmentally friendly pest trapping device mainly consists of a casing and a lure structure.

[0006] The casing includes a baffle and a trap chamber made of degradable material; the baffle is inserted into the top of the trap chamber and maintains a fixed distance, and the diameter of the baffle is larger than the diameter of the trap chamber; the top of the trap chamber has circumferentially distributed conical holes, the diameter of which gradually decreases from top to bottom; the side of the trap chamber has multiple sets of circumferentially distributed conical sleeves, which are connected to the interior of the trap chamber and have a diameter that gradually decreases from the outside to the inside.

[0007] The attractant structure includes a film made of degradable material and an insect-attracting adhesive coated on the surface of the film; the film is placed in a disc shape inside the trap chamber and distributed above and / or below the conical sleeve.

[0008] Furthermore, the inner wall of the trapping chamber is fixed with a limiting ring for supporting the lure structure.

[0009] Furthermore, the trapping chamber has a split structure, including a main chamber and a bottom plate; the bottom of the main chamber is tapered, and the bottom plate is threaded to the tapered part of the main chamber, with a conical sleeve located above the bottom plate.

[0010] Furthermore, the length of the conical sleeve located inside the trap chamber is greater than the diameter of the limiting ring.

[0011] Furthermore, the bottom of the baffle has circumferentially distributed insertion rods, and the top of the trap chamber has insertion holes that match the insertion rods, with the insertion holes offset from the conical holes.

[0012] Furthermore, the top of the baffle protrudes outward to form an arc surface, and a retaining ring is fixed to the outer surface of the insertion rod, with the inner diameter of the retaining ring being larger than that of the insertion hole.

[0013] Furthermore, a light-emitting block coated with insect-attracting fluorescent powder is installed at the center of the top of the trapping chamber, and the height of the light-emitting block is less than the gap between the baffle and the trapping chamber.

[0014] Furthermore, a modified cellulose membrane for collecting insects is adhered to the bottom of the trapping chamber.

[0015] Furthermore, the bottom of the base plate extends outwards and its diameter gradually decreases, with the extended part being conical.

[0016] Furthermore, the top outer wall of the trapping chamber extends horizontally outward to form a flattened, extended section.

[0017] Compared with the prior art, the beneficial effects of this utility model include:

[0018] 1. By using biodegradable bio-based materials to construct the main body of the trapping chamber, it can naturally decompose into water, carbon dioxide and humus within 3-6 months after burial, avoiding the risk of microplastic pollution caused by traditional plastic burial; at the same time, the degradation process is carried out simultaneously with the insect remains, and operators can achieve harmless disposal without opening the chamber for cleaning, cutting off the contact transmission chain of pathogenic microorganisms from the source and reducing biosafety protection costs;

[0019] 2. The multi-layer disc structure increases the contact surface area to 2-3 times that of the traditional cylindrical structure, improving the capture rate of harmful organisms. In addition, luminescent materials are added to attract a variety of harmful organisms. Attached Figure Description

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] like Figure 1 As shown in the figure, this embodiment introduces a biodegradable and environmentally friendly pest trapping device, which mainly includes a housing 1 and a lure structure 2.

[0028] The housing 1 includes a baffle 11 and a trapping chamber 12. The baffle 11 and the trapping chamber 12 are connected by a plug-in joint. Figure 2 As shown, the bottom of the baffle 11 has circumferentially distributed insertion rods 15, and the top of the trapping chamber 12 has insertion holes that match the insertion rods 15. To ensure a secure connection, a flexible layer can be provided on the surface of the insertion rods 15, which fits snugly with the insertion holes to achieve a stable connection. To prevent the insertion rods 15 from fully entering the insertion holes, a retaining ring 16 is fixed to the outer surface of the insertion rods 15. The inner diameter of the retaining ring 16 is larger than the insertion hole. When the retaining ring 16 contacts the trapping chamber 12, it prevents the baffle 11 from moving downward, thereby maintaining a fixed distance between the baffle 11 and the trapping chamber 12. The baffle 11 is preferably made of a non-degradable material for recycling, but a degradable material can also be selected according to actual needs. The diameter of the baffle 11 is larger than the diameter of the trapping chamber 12 to create a rainproof and light-shielding effect, and the top of the baffle 11 bulges outward to form an arc surface to drain rainwater.

[0029] At the top center of the trapping chamber 12, there is a light-emitting block 3 with a surface coated with insect-attracting fluorescent powder. The height of the light-emitting block 3 is less than the gap between the baffle 11 and the trapping chamber 12, so the light-emitting block 3 does not contact the baffle 11. The light-emitting block 3 coated with insect-attracting fluorescent powder is made of environmentally friendly material, that is, the light-emitting block 3 itself is made of biodegradable material. The insect-attracting fluorescent powder can be made of luciferin or fluorescent protein extracted from luminescent fungi, ensuring the overall environmental friendliness.

[0030] like Figure 3 and Figure 4 As shown, the trapping chamber 12 is made of biodegradable material, preferably straw composite material, but other biodegradable materials can also be used. The trapping chamber 12 adopts a split structure, including a main chamber and a bottom plate; the bottom of the main chamber is tapered, and the bottom plate is threaded to the tapered part of the main chamber. The attractant structure 2 can be placed inside the main chamber by disassembling the bottom plate. The top of the main chamber has circumferentially distributed conical holes, with the diameter gradually decreasing from top to bottom. Harmful organisms can enter the interior of the main chamber through the conical holes, and the conical holes and insertion holes are staggered and do not interfere with each other. Since the baffle 11 maintains a fixed distance from the top of the main chamber, the conical holes are not blocked by the baffle 11.

[0031] To prevent harmful organisms from falling into the main chamber after the base plate is rotated off, a modified cellulose membrane (not shown in the figure) for insect collection is adhered to the bottom of the trapping chamber 12. This membrane seals the bottom of the main chamber, ensuring that no harmful organisms fall even if the base plate detaches. In practical applications, if the chamber needs to be buried underground, the base plate can have a conical structure, meaning the bottom extends outwards with a gradually decreasing diameter, forming a cone shape to facilitate insertion into the ground. If the chamber is not buried underground, a conical structure is unnecessary. The modified cellulose membrane can be replaced with an enzyme-triggered degradation membrane.

[0032] The top outer wall of the main compartment extends horizontally outward to form a flattened extension (not shown in the figure), which can be used for hanging or for mounting the main compartment by opening holes in the flattened extension. If hanging is not required, the flattened extension is not needed. Multiple sets of interconnected conical sleeves 13 are provided on the side walls of the main compartment. The diameter of the conical sleeves 13 gradually decreases from the outside to the inside, making it difficult for harmful organisms to escape after entering. Each set of conical sleeves 13 is circumferentially distributed, and a fixed distance is maintained between adjacent sets of conical sleeves 13. Parts of the conical sleeves 13 extend into the interior of the main compartment, forming an insect-attracting track to guide harmful organisms.

[0033] like Figure 3As shown, the attractant structure 2 consists of a thin film made of degradable material and an insect-attracting adhesive coated on the surface of the film. The adhesive is preferably a pH-responsive adhesive (rosin / castor oil composite system) with an initial viscosity ≥800 Pa·s. It degrades within a certain time upon contact with organic acids produced by the decay of insects, and the degradation products are water-soluble oligomers. Furthermore, the adhesive can be combined with pheromone-releasing microspheres. The film is placed in a disc-like shape inside the main compartment and distributed above and / or below the conical sleeve 13, thus expanding the attractant area of ​​the film through the disc design. In practical applications, a grid-like or other shapes can also be used to meet the need for expanding the attractant area.

[0034] To ensure the attraction structure 2 is securely placed within the main chamber, a limiting ring 14 is provided on the inner wall of the main chamber to support the attraction structure 2. The outermost edge of the attraction structure 2 is not coated with adhesive and contacts the inner wall of the main chamber, while its bottom contacts the limiting ring 14. The conical sleeve 13 extends from inside the main chamber to above or below the inner part of the limiting ring 14, allowing harmful organisms entering through the conical sleeve 13 to enter the attraction structure 2 without being blocked by the limiting ring 14.

[0035] In practical applications, the attractant structure 2 is first placed between adjacent conical sleeves 13 inside the main chamber, or above / below the conical sleeves 13. Then, the modified cellulose membrane is used to seal the bottom of the main chamber and threaded onto the base plate. The baffle 11 is inserted into the top of the main chamber. The device is then placed in the designated location to attract harmful organisms into the main chamber. After a period of use or when the main chamber reaches its maximum capacity, the baffle 11 can be removed, and the remaining parts of the device can be buried. Because it uses biodegradable and environmentally friendly materials, it will not cause harm to the environment.

[0036] This embodiment uses biodegradable bio-based materials to construct the main body of the trapping chamber 12, which can naturally decompose into water, carbon dioxide, and humus within 3-6 months after burial, avoiding the microplastic pollution risk caused by traditional plastic burial. At the same time, the degradation process occurs simultaneously with the insect remains, and operators can achieve harmless disposal without opening the chamber for cleaning, cutting off the contact transmission chain of pathogenic microorganisms at the source and reducing biosafety protection costs. The multi-layer disc structure increases the contact surface area to more than 2-3 times that of the traditional cylindrical structure, improving the capture rate of harmful organisms, and the addition of luminescent materials can attract a variety of harmful organisms.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
