Description

Technical Field

[0001] This utility model relates to the field of mollusc trapping technology, specifically a composite trapping and blocking device for invasive molluscs. Background Technology

[0002] Invasive mollusks refer to non-native species that harm ecosystems through human introduction or natural spread. Typical examples include the golden apple snail, the giant African snail, and the rose snail. They spread through trade, release, and other means, lacking natural predators, leading to a reduction in native species, agricultural losses, and public health risks.

[0003] Currently, physical trapping and chemical control methods are commonly used: Physical trapping: using the attraction of mollusks to set traps and confine them to containers; or using copper bar barriers to block migration through tactile stimulation.

[0004] Chemical control: For example, using metaldehyde solution to attract and kill insects, or mixing molluscicide with sand and spreading it. Care should be taken to avoid polluting water bodies.

[0005] Physical trapping containers have a small coverage area and require multiple installations, while chemical control solutions are prone to evaporation, resulting in insufficient long-lasting efficacy. Therefore, while balancing ecological safety and control efficiency, a combination of methods is needed for comprehensive management. This leads to the proposal of a composite trapping and barrier device for invasive mollusks. Utility Model Content

[0006] The purpose of this invention is to provide a composite trapping and blocking device for invasive mollusks, which solves the problems mentioned in the background art by combining multiple methods of trapping and blocking.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A composite trapping and barrier device for invasive mollusks includes a box body. The top of the box body curves inward to form an annular inclined platform. An annular groove is formed on the annular inclined platform. A support net is fixedly installed on the upper side of the inner side of the annular groove. An annular medicine tank is fixedly installed on the upper side of the inner side of the box body. A cotton pad is fixedly installed on the inner circumference of the annular medicine tank. The cotton pad is located in the annular groove and abuts against the lower side of the support net. The annular medicine tank has a through hole. A cotton column is inserted into the through hole. The upper end of the cotton column is connected to the cotton pad, and the lower end of the cotton column extends into the bottom of the annular medicine tank. A protective cover is installed on the upper side of the box body via a support member. A screw is fixedly installed on the lower side of the box body.

[0008] Specifically, the cotton columns consist of 6 to 8 columns evenly distributed around the circumference.

[0009] Specifically, the housing includes a frustum sidewall and a bottom shell. The top of the frustum sidewall is smoothly connected to an annular inclined platform. An internal threaded ring is fixedly installed on the lower inner side of the annular inclined platform. The internal threaded ring is screwed to the bottom shell. A screw is fixedly assembled at the center of the lower side of the bottom shell.

[0010] Furthermore, the lower surface of the frustum sidewall is 10 mm lower than the lower surface of the bottom shell.

[0011] Furthermore, a pair of grooves are provided at the bottom of the bottom shell.

[0012] Specifically, the support component includes a support cylinder, a retaining spring, and a support rod. The support cylinder and the support rod are fixedly installed on the upper side of the annular medicine tank, and the support cylinder and the support rod are symmetrically arranged. The support cylinder is connected and assembled with the annular medicine tank. The protective cover is fixedly installed with a pair of sleeves for passing through the support cylinder and the support rod. The support cylinder and the support rod are respectively clamped with a pair of retaining springs. Each pair of retaining springs is located at both ends of the sleeve. The top of the support cylinder is screwed with a cap.

[0013] Specifically, the bottom edge of the annular inclined platform is uniformly provided with protruding teeth.

[0014] Specifically, a pair of handles are fixedly installed on the side wall of the frustum.

[0015] Specifically, copper-plated wire mesh is installed between adjacent handles.

[0016] Compared with the prior art, the beneficial effects of this utility model are: Through the synergistic effect of physical barriers and chemical trapping, copper-plated wire mesh effectively blocks and guides mollusks to the enclosures, reducing the number of enclosures required. The ring-shaped medicine tank maintains the continuous moisture of the cotton pads through capillary adsorption of cotton columns, prolonging the duration of the medicine's effect. The overall solution balances ecological safety and control efficiency, achieving integrated "barrier-trapping-extermination" management, significantly reducing manual maintenance costs and environmental pollution risks.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Example content: Please see Figure 1 A composite trapping and barrier device for invasive mollusks is provided, comprising a box 2, the top of which is bent inward to form an annular inclined platform 6, the angle between the annular inclined platform 6 and the horizontal plane being 45° to 60°, forming a guide ramp for mollusks to move into the box.

[0021] The annular inclined platform 6 has an annular groove, and a support net 7 is fixedly installed on the upper side of the inside of the annular groove. The upper surface of the support net 7 is flush with the upper surface of the annular inclined platform 6, which facilitates the downward movement of molluscs, ensuring smooth crawling of the animals, and providing a carrier for subsequent contact of the drug solution through the mesh structure.

[0022] An annular medicine tank 3 is fixedly installed on the upper side of the inside of the box 2. The cross-sectional shape of the annular medicine tank 3 is adapted to the box 2 and the annular inclined platform 6 to increase the volume. The annular medicine tank 3 is used to store medicine for treating mollusks.

[0023] A cotton pad 10 is fixedly installed on the inner circumference of the annular medicine tank 3. The cotton pad 10 is located in the annular groove and abuts against the lower side of the support net 7. The cotton pad 10 is soft and can fill the grid of the support net 7, which is conducive to the contact of mollusks. The design of the cotton pad filling the grid of the support net 7 can ensure the penetration efficiency of the medicine.

[0024] The annular medicine tank 3 has a through hole, into which a cotton column 9 is inserted. The upper end of the cotton column 9 is connected to the cotton pad 10, and the lower end of the cotton column 9 extends into the bottom of the annular medicine tank 3. Through the capillary effect of the cotton column 9, the medicine is absorbed from the bottom of the tank to the cotton pad 10, forming a continuously moist contact surface.

[0025] In addition, to ensure the uniform distribution of the drug solution on the cotton pad 10, there are 6 to 8 cotton columns 9 evenly distributed in a circle. This design of evenly distributed cotton columns in a circle ensures the uniform distribution of the drug solution and avoids local drying which would affect the trapping effect.

[0026] Suitable medicinal solutions: Commonly used single-agent solutions: metaldehyde, molluscicide, etc.; compound formulation solutions: metaldehyde + carbaryl, metaldehyde + molluscicide ethanolamine salt; or other special solutions.

[0027] The above-mentioned solutions should be selected according to the specific crops, environment and mollusc species, and the instructions for use and safety regulations should be strictly followed.

[0028] A protective cover 5 is installed on the upper side of the box 2 via a support 4. The protective cover 5 is shaped like a hat, and its diameter is larger than the size of the top of the medicine tank to ensure rain and snow protection.

[0029] A rotary nail 1 is fixedly installed on the lower side of the box 2. The rotary nail 1 consists of a nail body and a rotating plate fixedly installed on the circumference of the nail body. Rotating the box 2 can insert the rotary nail 1 into the soil for fixation.

[0030] Structure of Box 2: The box 2 includes a frustum sidewall 22 and a bottom shell 23. The top of the frustum sidewall 22 is smoothly connected to the annular inclined platform 6. The upper end of the frustum sidewall 22 is small and the lower end is large. The inner side of the sidewall forms a steep slope and the outer side forms a gentle slope, which is conducive to the entry of mollusks but not conducive to the crawling out of mollusks.

[0031] An internal threaded ring is fixedly installed on the lower side of the annular inclined platform 6. The internal threaded ring is screwed to the bottom shell 23. The center of the lower side of the bottom shell 23 is fixedly assembled with the screw 1. The bottom shell 23 can be easily installed and disassembled from the side wall 22 of the frustum by means of threaded connection, which is convenient for assembly and maintenance.

[0032] Furthermore, the thread direction of the internal thread ring is matched with the thread direction of the spiral blade in the screw 1, ensuring that the thread tightening direction is consistent with the screw rotation direction during installation, preventing loosening during use.

[0033] The lower surface of the frustum sidewall 22 is 10mm lower than the lower surface of the bottom shell 23. After installation, the lower end of the frustum sidewall 22 extends into the soil, forming a seamless transition path.

[0034] The bottom of the base shell 23 is provided with a pair of grooves 21, which facilitates the application of torque on the base shell 23, thereby facilitating installation and disassembly.

[0035] Please see Figure 2 The structure of support member 4: The support component 4 includes a support cylinder 41, a retaining spring 42, and a support rod 43. The support cylinder 41 and the support rod 43 are fixedly installed on the upper side of the annular liquid tank 3, and the support cylinder 41 and the support rod 43 are symmetrically arranged. The support cylinder 41 is connected to the annular liquid tank 3. A pair of sleeves for passing through the support cylinder 41 and the support rod 43 are fixedly installed on the protective cover 5. A pair of retaining springs 42 are respectively snapped into the support cylinder 41 and the support rod 43. Each pair of retaining springs 42 is located at both ends of the sleeve. A cap is screwed to the top of the support cylinder 41.

[0036] The support component 4 adopts a sleeve structure with double-ended fixing of the retaining spring 42, which can ensure the wind resistance of the protective cover 5 and is easy to assemble. In addition, opening the cover allows for direct replenishment of medicine from the support cylinder 41 into the annular medicine tank 3, making operation convenient.

[0037] The bottom edge of the annular inclined platform 6 is evenly provided with protruding teeth 8, which are used to prevent soft-bodied animals from crawling out and serve as a barrier.

[0038] Please see Figure 3 The function of handle 11: A pair of handles 11 are fixedly installed on the side wall 22 of the frustum. The handles 11 make it easy to pick up the whole and move it. They also make it easy to apply torque to the box 2 during installation, making it convenient to apply force.

[0039] When the barrier is set up, copper-plated wire mesh 12 is installed between adjacent handles 11 by straps. The copper-plated wire mesh 12 blocks between adjacent boxes 2, and prevents passage by the tactile stimulation principle of copper, thereby guiding the molluscs to approach the box 2.

[0040] How the example works: When setting: Select an appropriate number of boxes 2 according to the required barrier range, and screw the box 2 and screw nail 1 into the soil by screwing the handle 11 to install the whole in a stable manner. The lower edge of the side wall 22 of the truncated cone extends into the soil, which is conducive to the crawling of mollusks.

[0041] Then, copper-plated wire mesh 12 is installed between adjacent boxes 2 to achieve a large-scale barrier.

[0042] The prepared drug solution is filled into the annular drug solution tank 3 through the support tube 41, and the drug solution is absorbed onto the cotton pad 10 through the cotton column 9, so as to achieve continuous supply and long-term trapping.

[0043] When using: When mollusks (such as snails) move, their mucus comes into contact with the copper on the copper-plated wire mesh 12, which produces a chemical reaction and generates electrical nerve signals, similar to the feeling of electric shock, causing discomfort and causing them to avoid the area. At the same time, the drug also induces the mollusks to concentrate in the box 2. After the mollusks climb onto the annular inclined platform 6, they come into contact with the drug seeping out from the support net 7, which causes paralysis, and they eventually fall into the box 2 for storage.

[0044] In addition, the steep slope of the box and the protruding teeth 8 form a double barrier to prevent mollusks that have entered the box 2 from escaping.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
