Description
Technical Field
[0001] This utility model relates to the field of golden apple snail control technology, specifically a double-sided snail trap. Background Technology
[0002] Golden apple snails feed on the young shoots, tender leaves, and roots of aquatic plants such as rice, water chestnuts, lotus roots, and water spinach, causing the most significant damage during the transplanting and seedling stages in rice paddies. Statistics show that in uncontrolled rice paddies, golden apple snails can lead to a 20%–40% reduction in rice yield, and in severe cases, even total crop failure. Their sharp radula structure allows them to quickly scrape and consume crop tissue, causing plants to wither or stunt growth, directly impacting crop yield and quality. In aquatic systems, the metabolic activity of large numbers of golden apple snails increases the levels of ammonia nitrogen and organic matter in the water, reduces dissolved oxygen concentration, and affects water quality and the survival of other aquatic organisms. Furthermore, their egg-laying behavior (laying pink egg masses on waterside vegetation or embankments) can clog irrigation ditches, affecting the normal operation of agricultural water conservancy facilities and damaging the riparian landscape ecology. To control the population of golden apple snails, farmers often rely on chemical pesticides (such as niclosamide). However, frequent use of pesticides not only increases agricultural costs (the cost of control per acre can reach tens to hundreds of yuan) but also disrupts the ecological balance of farmland, leading to water pollution and a reduction in natural predators (such as fish and frogs). For golden apple snails in river systems, the methods used are mostly manual capture and washing away the egg masses with water guns, which are time-consuming, labor-intensive, costly, and inefficient. Therefore, a new golden apple snail capture device is needed to solve these problems. Utility Model Content
[0003] This invention provides a double-sided snail-attracting box, which can solve the technical problems existing in various methods of controlling the number of golden apple snails.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a double-sided snail trap, comprising: a trap body, wherein at least one snail inlet is provided on the lower part of both sides of the trap body; and an escape prevention component, disposed inside the snail inlet, wherein the escape prevention component includes a plurality of levers arranged in a row that can swing around their upper ends, the levers having a first position and a second position. In the first position, the levers block the snail inlet and can rotate unidirectionally inward under the action of an external force from the outside to the inside. When the levers are subjected to an external force from the outside to the inside, they rotate inward to reach the second position and return to the first position when the external force is lost. When the snail trap is installed in the activity area of the golden apple snail, the golden apple snails can be lured into the trap body on their own. The escape prevention component can prevent the golden apple snails that have entered the trap body from escaping again, greatly improving the trapping efficiency, without environmental pollution or damage, and with low labor costs.
[0005] Preferably, the anti-escape component also includes a rotating shaft seat at both ends of the upper side of the screw inlet, with a rotating shaft connected between the rotating shaft seats. The upper end of the stop lever is sleeved on the rotating shaft. The rotating shaft seat can support the rotating shaft, and the stop lever can rotate freely on the rotating shaft without interfering with each other.
[0006] Preferably, the upper end of the stop lever is connected to a bushing, which is sleeved on the rotating shaft. The bushing and the stop lever can be detachably connected, which facilitates the replacement of the stop lever and makes the rotational connection between the stop lever and the rotating shaft simpler and more reasonable.
[0007] Preferably, a limit block is provided laterally between the rotating shaft seats. When the stop bar contacts the limit block, it is in the first position. The limit block ensures that the stop bar can only rotate from the outside to the inside when it is in the first position. Each stop bar can be limited by the limit block.
[0008] Preferably, when the stop lever is in the first position, the distance between its upper end and the screw inlet is less than the distance between its lower end and the screw inlet. This way, the stop lever will not be in a vertically drooping state in the first position, and the stop lever can be kept in the first position under its own weight.
[0009] Preferably, the lower two sides of the box are provided with guide slopes extending to the inlet. The design of the guide slopes conforms to the crawling habits of the golden apple snail, which can guide the golden apple snail to move smoothly along the slopes to the inlet, reduce its wandering and deviation outside the box, and increase the probability of entering the inlet.
[0010] Preferably, the lower end of the box is provided with at least one plug-in fixing part, so that the entire box can be inserted into the ground of the installation environment. The fixing method is simple and reliable, requiring no additional installation tools, and is suitable for various complex field environments, ensuring that the snail trapping box can play a stable role for a long time.
[0011] Preferably, a partition plate parallel to the side wall where the snail inlet is located is inserted into the middle of the box. A support plate connected to the side wall where the snail inlet is located is provided at the upper end of the partition plate. The partition plate divides the internal space of the box into multiple trapping spaces, which not only increases the space for placing bait, but also allows the golden apple snails to be more evenly distributed in various areas under the guidance of the partition plate after entering the box, avoiding crowding or escape caused by concentrating in one place.
[0012] Preferably, the upper part of the box is provided with an openable box cover, and the side of the box cover is equipped with a locking part, so that the staff can open the box cover to clean the golden apple snails inside.
[0013] Preferably, bait is placed inside the box to improve the efficiency of inducing golden apple snails to enter the box.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] With its simple structure and easy installation, the snail trap can be installed in the area where golden apple snails are active, and the snails can be lured into the trap on their own. The escape prevention component can prevent the golden apple snails from escaping again after entering the trap, which greatly improves the trapping efficiency, without environmental pollution or damage, and with low labor costs.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] This utility model addresses the technical problems existing in current methods for controlling the population of golden apple snails. For example... Figure 1-4 As shown, the following technical solution is provided: a double-sided snail trap, comprising: a box body 1, wherein at least one snail inlet 12 is provided on the lower part of both sides of the box body 1; an anti-escape component 10, disposed inside the snail inlet 12, wherein the anti-escape component 10 includes a plurality of levers 13 arranged in a row that can swing around their upper ends, wherein the levers 13 have a first position and a second position. In the first position, the levers 13 block the snail inlet 12 and can rotate inward unidirectionally under the action of an external force from the outside to the inside. When the levers 13 are subjected to an external force from the outside to the inside, they rotate inward to reach the second position and return to the first position when the external force is lost. When the snail trap is installed in the activity area of the golden apple snail, the golden apple snail can be lured into the box body 1 on its own. The anti-escape component 10 can prevent the golden apple snails that have entered the box body 1 from escaping again, which greatly improves the trapping efficiency, has no environmental pollution or damage, and has low labor costs.
[0024] In this embodiment, the anti-escape component 10 also includes a rotating shaft seat 17 disposed at both ends of the upper side of the screw inlet 12. A rotating shaft is connected between the rotating shaft seats 17. The upper end of the stop lever 13 is sleeved on the rotating shaft. The rotating shaft can be supported by the rotating shaft seat 17, and the stop lever 13 can rotate freely on the rotating shaft without interfering with each other.
[0025] Specifically, the stop lever 13 resets using its own gravity, eliminating the need for an additional power source and reducing the complexity of the mechanical structure and the probability of failure. When the apple snail pushes the stop lever from the outside in, the upper end of the stop lever 13 is hinged to the pivot, and the lower end rotates inward under the thrust, creating a sufficient passage gap. After the external force disappears, the stop lever automatically swings back to the first position due to the lower center of gravity, blocking the snail's entry port and preventing the apple snail from climbing back and escaping. This dynamic swinging structure provides less resistance to the entry of the apple snail and can adapt to the pushing force of apple snails of different sizes, avoiding the "snail jamming" or "rejection" phenomenon caused by the fixed baffle.
[0026] In this embodiment, the upper end of the stop lever 13 is connected to a bushing 19, which is sleeved on the rotating shaft. The bushing 19 and the stop lever 13 can be detachably connected by means of threads or snaps, which facilitates the replacement of the stop lever after wear, reduces maintenance costs, and makes the rotational connection between the stop lever 13 and the rotating shaft simpler and more reasonable. The cooperation between the rotating shaft seat 17 and the bushing 19 enables the stop lever to rotate with low friction, ensuring that the apple snail can open the channel with minimal thrust, thus improving the entry efficiency.
[0027] In this embodiment, a limiting block 15 is laterally arranged between the rotating shaft seats 17. When the stop lever 13 contacts the limiting block 15, it is in the first position. The limiting block 15 ensures that the stop lever 13 can only rotate from the outside to the inside when in the first position. Each stop lever 13 can be limited by the limiting block 15. Specifically, the limiting block 15 precisely limits the swing boundary of the stop lever in the first position, so that the stop lever 13 forms a tight fit with the edge of the screw inlet when sealing, avoiding the extrusion of the golden apple snail due to excessive gap. At the same time, the lateral arrangement of the limiting block 15 forms a "rigid stop surface" to prevent the stop lever from swinging excessively to the reverse opening, ensuring the reliability of the one-way passage logic.
[0028] To ensure the stop lever 13 remains in the first position, the distance between its upper end and the screw inlet 12 is less than the distance between its lower end and the screw inlet 12 when in the first position. This prevents the stop lever 13 from hanging vertically downwards and allows it to remain in the first position under its own weight. Specifically, the tilt angle of the stop lever 13 is preferably 15°-30°, which matches the movement trajectory of the apple snail climbing from the outside to the inside. When the apple snail crawls to the screw inlet, the direction of the pushing force is consistent with the direction of the force on the tilted surface of the stop lever, making it easier to push the stop lever. When the apple snail attempts to escape from the box in the opposite direction, it needs to push the stop lever downwards. At this time, the stop lever forms a self-locking effect due to gravity and the tilted surface. The greater the reverse pushing force, the tighter the fit between the stop lever and the screw inlet, effectively preventing escape. Moreover, the gravity-assisted reset function of the tilted stop lever is more stable, requiring no additional springs or elastic components, avoiding reset failure due to elastic fatigue, making it particularly suitable for outdoor use scenarios where the snail is immersed in a humid environment for a long time.
[0029] In addition, side baffles extending inward can be provided at both ends of the screw inlet 12. Slots 20 can be provided on the side baffles. Rubber bands or pull ropes can be provided between the two slots 20. The purpose is to limit the extreme position of the inward rotation of the stop lever 13. The rubber band can also allow the stop lever 13 to be reset better.
[0030] In this embodiment, the lower sides of the box 1 are provided with guide slopes 11 extending to the inlet 12. The design of the guide slopes 11 conforms to the crawling habits of the golden apple snail, which can guide the golden apple snail to move smoothly towards the inlet along the slope, reduce its wandering and deviation outside the box, and increase the probability of entering the inlet. The guide slopes 11 adopt a smooth curved surface design with a slope of 30°-45°, which not only conforms to the climbing mechanics of the golden apple snail's abdominal foot muscles, but also attracts it to move towards the inlet through visual and tactile guidance (such as color contrast or texture).
[0031] In this embodiment, the lower end of the box 1 is provided with at least one plug-in fixing part 2, so that the entire box 1 can be inserted into the ground of the installation environment. The fixing method is simple and reliable, requiring no additional installation tools, and is suitable for various complex outdoor environments. This ensures that the snail trap can function stably for a long time. Specifically, the plug-in fixing part 2 can be set at both ends of the lower side of the box 1, and can be directly inserted into soft ground such as paddy field soil and pond banks. When the insertion depth is ≥15cm, it can resist the impact of water flow and the impact force of golden apple snails (measured pull-out force ≥50N). A barbed structure design can be provided on the plug-in fixing part 2 to prevent the box from being accidentally pulled out, which is especially suitable for rainy seasons or environments with fluctuating water levels.
[0032] In this embodiment, a partition 16 parallel to the side wall where the snail inlet 12 is located is inserted into the middle of the box 1. A support plate 14 connected to the side wall where the snail inlet 12 is located is provided at the upper end of the partition 16. The partition 16 divides the internal space of the box 1 into multiple trapping spaces, which not only increases the space for placing bait, but also allows the golden apple snails to be more evenly distributed in various areas under the guidance of the partition 16 after entering the box, avoiding crowding or escape caused by concentrating in a certain position. At the same time, the rigid connection between the support plate 14 and the side wall of the box enhances the impact resistance of the partition, preventing the partition from deforming when the golden apple snails move in the box, and ensuring structural stability during long-term use.
[0033] In this embodiment, the upper end of the box 1 is provided with an openable box cover 3, and the side of the box cover 3 is equipped with a locking part 4, which makes it convenient for staff to open the box cover 3 to clean the golden apple snails inside. The anti-theft structure of the locking part 4 can prevent wild animals such as birds and raccoons from opening the box cover and destroying the bait or pecking at the golden apple snails inside the box.
[0034] Meanwhile, bait is placed inside the box 1 to improve the induction efficiency of golden apple snails into the box 1. The bait can be placed in a special container, which can improve the efficiency of bait placement and replacement, and also facilitate the cleaning of the inside of the box 1. The bait can be cut into sections of rice seedlings, tender stems of water chestnuts, lotus leaf sheaths, taro peels, etc.
[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0036] Furthermore, in this utility model, descriptions involving terms such as "primary," "secondary," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "primary" or "secondary" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.
[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0038] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.
