Description

Technical Field

[0001] This utility model belongs to the field of golden apple snail treatment technology, specifically relating to a golden apple snail barrier device that is easy to assemble and disassemble. Background Technology

[0002] In agricultural production, the control of golden apple snails is crucial. Currently, the main control methods include biological control, chemical control, and physical control. Biological control, such as rice-fish and duck farming, is difficult for these organisms to ingest as the shells of golden apple snails harden, and may pollute the aquatic environment. Chemical control is a widely used method at present, using chemical agents such as molluscicides and methyl methacrylate, but it easily causes mass mortality of fish and other aquatic organisms, damaging the aquatic ecosystem. Physical control uses an inner and outer netting system for interception, or inserts bamboo poles and wooden sticks into rice paddies to trap and collect golden apple snail eggs. However, these devices have many drawbacks, such as only trapping and collecting snails in a very small area, making it difficult to catch all the snails both above and below water, resulting in very low efficiency.

[0003] Existing golden apple snail interception devices also have several problems in practical applications. Traditional installation methods relying on fixed poles are cumbersome in farmland settings, requiring significant manpower for pole installation, resulting in high labor costs and low efficiency. Furthermore, they are difficult to adapt to complex terrains such as steep slopes in ditches or uneven surfaces, failing to create a seamless, enclosed environment, allowing golden apple snails to escape and rendering them ineffective. In addition, while some traditional double-net structures can intercept debris and block golden apple snails, their cumbersome installation process increases the difficulty and workload of actual use.

[0004] To address this, we propose a snail barrier device that is easy to assemble and disassemble, adaptable to complex terrain, and efficiently integrates the functions of intercepting debris and blocking snails, thereby improving the snail control effect, reducing agricultural production costs, and protecting the farmland ecological environment. Utility Model Content

[0005] The purpose of this invention is to provide a snail barrier device that is easy to assemble and disassemble, adaptable to complex terrain, and efficiently integrates the functions of intercepting debris and blocking snails, thereby improving the snail control effect, reducing agricultural production costs, and protecting the farmland ecological environment.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An easy-to-assemble and disassemble snail barrier device includes two magnetic bases, and a double-net integrated assembly is magnetically attached between the two magnetic bases. A ring is installed inside the double-net integrated assembly, and four sets of rotating components are arranged inside the ring. Each rotating component is provided with a fan-shaped opening and closing plate.

[0008] Furthermore, the magnetic base consists of a first housing and a plurality of first magnetic blocks disposed inside the first housing, and the first housing has mounting holes.

[0009] Furthermore, a sealing layer is provided inside the mounting hole.

[0010] Furthermore, the dual-net integrated assembly includes two second housings, a coarse mesh, and a fine mesh bag. Each second housing contains a second magnetic block, and the first magnetic block attracts the second magnetic block. The coarse mesh is positioned between the two second housings. A first rectangular plate is positioned on the back of the coarse mesh. A second rectangular plate is positioned on the side of the fine mesh bag closest to the first rectangular plate. The first rectangular plate has a Velcro surface and a slot, and the second rectangular plate has a Velcro hook surface and a buckle.

[0011] Furthermore, the hook and loop side of the Velcro are attached together, and the buckle and the slot cooperate with each other.

[0012] Furthermore, the rotating assembly includes a through groove formed on the ring, a rotating shaft rotatably disposed inside the through groove, a fixed sleeve and two torsion springs disposed on the rotating shaft, the fixed sleeve being disposed between the two torsion springs, and the fan-shaped opening and closing plate being disposed outside the fixed sleeve.

[0013] Furthermore, the bottom of the fine mesh bag is provided with a discharge port.

[0014] The technical effects achieved by this utility model are as follows:

[0015] 1. Effectively intercepting golden apple snails. Golden apple snails mainly enter rice paddies with the irrigation water, feeding on rice seedlings and causing large-scale seedling loss; they also eat the tillers, leading to reduced rice yield. By setting appropriately sized mesh, large debris such as dead branches and fallen leaves can be blocked, as well as adult snails, effectively preventing golden apple snails from entering farmland with irrigation water, preventing their spread, and protecting rice from damage.

[0016] 2. Adaptable to different slopes and unevenness of ditches. Through its magnetic structure, it can fit tightly against the wall of the paddy field inlet ditch, forming a closed environment and preventing golden apple snails from entering the paddy field through gaps.

[0017] 3. The structure is stable and durable, the net is not easy to fall off or collapse, it can maintain a stable interception state for a long time and continue to play its role; and the operation of replacing the net is simple and convenient.

[0018] 4. Simple and convenient operation. It is fixed directly by magnetic attraction, eliminating the need for laborious insertion of a fixing rod, and can be operated by a single person. The overall structure design is relatively simple, making installation and use convenient. Users can easily master the relevant operations, requiring no complicated techniques or tools, making it easy to promote and apply in agricultural and other similar settings.

[0019] 5. Advantages compared to existing models. Compared to the current "internal network + external network" installation model promoted in rice fields, this device only requires installation on a single network to achieve the same interception capability. Attached Figure Description

Detailed Implementation

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figures 1-4 As shown, a snail barrier device that is easy to assemble and disassemble includes two magnetic bases 1, and a double-net integrated component 2 is magnetically attached between the two magnetic bases 1. A ring 3 is installed inside the double-net integrated component 2, and four sets of rotating components are arranged inside the ring 3. Each rotating component is provided with a fan-shaped opening and closing plate 5.

[0029] This device breaks through the traditional installation method that relies on fixed poles. It achieves quick and easy attachment and fixation of the barrier net to the ditch wall through magnetic design. No laborious pole insertion or complicated tools are required. A single person can complete the installation / disassembly, which greatly reduces the operation threshold and solves the problems of high labor costs and low operation efficiency in farmland.

[0030] The dual-net function of "intercepting debris and blocking golden apple snails" is integrated into a single net. The single net installation is made convenient through the dual-net integrated component 2, while retaining the functional division of the dual nets (outer layer to block debris, inner layer to collect snails). This not only solves the problem of cumbersome installation of traditional dual nets, but also enhances the synergy between interception and collection.

[0031] The magnetic base 1 consists of a first housing 6 and a plurality of first magnetic blocks 7 disposed inside the first housing 6, and the first housing 6 has mounting holes 8. A nail passes through the mounting holes 8 to fix the base, and is magnetically connected to the dual-mesh integrated assembly 2 through the first magnetic blocks 7.

[0032] Furthermore, the magnetic base 1 is made of flexible material, such as rubber / silicone. The magnetic base 1 made of flexible material has a certain degree of flexibility and can flexibly adjust the fitting angle and position according to the slope and surface unevenness of the ditch to form a seamless closed environment. This breaks through the limitations of traditional fixed nets that are difficult to adapt to complex terrain and ensures that the closed interception state is always maintained in diverse farmland ditches.

[0033] Furthermore, a sealing layer is provided inside the mounting hole 8 to prevent water from entering the first housing 6 and causing corrosion of the first magnetic block 7.

[0034] The magnetic attraction force of the first magnetic block 7 and the second magnetic block 12 is ≥50N, ensuring that they will not fall off under the impact of water flow at a velocity of 0.5m / s.

[0035] The coarse mesh 10 has a mesh size of 10mm×10mm, while the fine mesh bag 11 (mesh size of 3-5mm) can intercept snails (snail diameter ≥5mm) and snail eggs.

[0036] The dual-net integrated component 2 includes two second housings 9, a coarse mesh 10, and a fine mesh bag 11. Each second housing 9 has a second magnetic block 12 inside. The first magnetic block 7 is attracted to the second magnetic block 12. The coarse mesh 10 is arranged between the two second housings 9. A first rectangular plate 13 is arranged on the back of the coarse mesh 10. A second rectangular plate 14 is arranged on the side of the fine mesh bag 11 near the first rectangular plate 13. The first rectangular plate 13 has a Velcro surface and a slot, and the second rectangular plate 14 has a Velcro hook surface and a buckle.

[0037] By attaching the hook and loop sides of the Velcro together, and using the clips and slots to match, the coarse mesh 10 and the fine mesh bag 11 can be easily installed and removed.

[0038] The rotating assembly includes a through groove 15 formed on the ring 3. A rotating shaft 16 is rotatably arranged inside the through groove 15. A fixed sleeve 17 and two torsion springs 18 are arranged on the rotating shaft 16. The fixed sleeve 17 is arranged between the two torsion springs 18. A fan-shaped opening and closing plate 5 is arranged on the outside of the fixed sleeve 17.

[0039] When there is water flow, the water flow impacts the fan-shaped opening and closing plate 5, and the fan-shaped opening and closing plate 5 opens under the impact of the water flow, so that the golden apple snail enters the fine mesh bag 11. When there is no water flow impact, the torsion spring 18 drives the fan-shaped opening and closing plate 5 to return to its original position and seal it, preventing the golden apple snail from escaping.

[0040] The bottom of the fine mesh bag 11 is equipped with a discharge port (not shown in the figure). After people remove the fine mesh bag 11, the golden apple snails are discharged through the discharge port.

[0041] The working principle of this utility model is as follows: First, the magnetic design enables the quick attachment and fixation of the barrier net to the ditch wall, eliminating the need for laborious insertion rods or complex tools. Installation and disassembly can be completed by a single person, significantly reducing the operational threshold and solving the problems of high labor costs and low operational efficiency in farmland scenarios. The use of Velcro hooks and hooks, along with the matching of clips and slots, allows for easy installation and disassembly of the coarse barrier net 10 and the fine mesh bag 11. When there is water flow, the water impacts the fan-shaped opening plate 5, causing it to open and allowing the golden apple snail to enter the fine mesh bag 11. When there is no water flow, the torsion spring 18 drives the fan-shaped opening plate 5 back to its original position for sealing, preventing the golden apple snail from escaping. This device can adapt to complex terrain and efficiently integrates the functions of intercepting debris and preventing golden apple snails, improving the control effect of golden apple snails, reducing agricultural production costs, and protecting the farmland ecological environment.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
