Description

Technical Field

[0001] This utility model relates to the field of golden apple snail control technology, specifically a wall-mounted golden apple snail trapping box. 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 wall-mounted golden apple snail trapping box, which can solve the technical problems existing in various current methods of controlling the number of golden apple snails.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wall-mounted golden apple snail trapping box, comprising a box body, at least one snail inlet provided on the lower front side of the box body, a hanging fixing component provided on the box body, and a guide slope extending upward from the rear side of the box body to the front side of the snail inlet provided on the lower side of the box body. An anti-escape component is installed on the inner side of the snail inlet, the anti-escape component comprising 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. By hanging the trapping box in the activity area of ​​the golden apple snails, the snails can be lured into the box body on their own. The anti-escape component can prevent the golden apple snails that have entered the box 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 inlet is provided with inwardly extending side baffles at both ends, which can guide the apple snail.

[0010] Preferably, the mounting fastener is at least one hook installed on the top of the box, which can be used to hang on a hook or protrusion at the installation location, which is simple and convenient.

[0011] Preferably, the mounting fastener also includes a connecting strip provided on the lower side of the box, and the connecting strip is provided with multiple connecting holes, so as to facilitate the fixing of the lower end of the box through the connecting strip and connecting holes.

[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 wall-mounted structure, it is easy to install and is especially suitable for installation on the riverbank. After installation, it can lure golden apple snails into the box on their own. The anti-escape component can prevent the golden apple snails from escaping again after entering the box, 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 wall-mounted golden apple snail trapping box, including a box body 1, at least one snail inlet 12 is provided on the lower front side of the box body 1, a hanging fixing component is provided on the box body 1, a guide slope 11 extending upward from the rear side of the box body 1 to the front side of the snail inlet 1 is provided on the lower side of the box body 1, an anti-escape component 10 is installed on the inner side of the snail inlet 12, the anti-escape component 10 includes a plurality of baffles 13 arranged in a row that can swing around their upper ends, the baffles 13 having In the first and second positions, the stop bar 13 blocks the inlet 12 and can rotate inward unidirectionally under the action of an external force from the outside to the inside. When the stop bar 13 is subjected to an external force from the outside to the inside, it rotates inward to reach the second position and returns to the first position when the external force is lost. The trapping box is hung in the activity area of ​​the golden apple snail, which can lure the golden apple snail into the box 1 on its own. The anti-escape component 10 can prevent the golden apple snail that has entered the box from escaping again, which greatly improves the trapping efficiency, without environmental pollution and damage, and with low labor costs.

[0024] Specifically, the guide slope 11 extends upward from the rear of the box to the front inlet 12, forming a slope of approximately 30°-45° (optimized based on the climbing habits of the golden apple snail). This utilizes the snail's phototaxis or feeding tendency to guide it along the slope to the inlet, reducing trapping failures due to unclear paths. Furthermore, the surface of the guide slope 11 can be designed with a rough texture (such as bumps or ridges) to increase the snail's climbing friction and prevent slipping due to wetness. The slope of the guide slope 11 is flush with the bottom of the inlet 12, creating an unobstructed passage and improving the entry efficiency for older golden apple snails (with thick shells and slow crawling).

[0025] 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 seats, and the stop lever can rotate freely on the rotating shaft without interfering with each other.

[0026] 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.

[0027] 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 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. 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 and improve the entry efficiency.

[0028] 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 ensures that the stop lever can only rotate from the outside to the inside when it is in the first position. Each stop lever can be limited by the limiting block. 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 it is blocked, 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.

[0029] In this embodiment, when the stop lever 13 is 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. This ensures that the stop lever is not vertically drooping in the first position, and it can maintain this 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 thrust 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, due to gravity and the action of the tilted surface, the stop lever forms a self-locking effect. The greater the reverse thrust, 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 extended periods.

[0030] In this embodiment, the two transverse ends of the screw inlet 12 are provided with inwardly extending side baffles 6, which can guide the golden apple snail. A slot 20 can be provided on the side baffle, and a rubber band or pull rope 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.

[0031] In this embodiment, the hanging fastener is at least one hook 5 installed on the top of the box 1, which can be used to hang on hooks or protrusions at the installation position, which is simple and convenient. The hanging fastener also includes a connecting strip 14 set on the lower side of the box 1. The connecting strip 14 is provided with multiple connecting holes, which facilitates the fixing of the lower end of the box 1 through the connecting strip 14 and the connecting holes. Specifically, by combining the top hook 5 and the bottom connecting strip 14, it can be directly suspended in areas where golden apple snails are active, such as river walls and farmland ridges. No additional tools are required for installation, and it is adaptable to walls with different slopes (such as vertical riverbanks and sloping field ridges), solving the problem of cumbersome installation caused by traditional trapping devices that need to be buried or floated. Moreover, it enhances the stability of the device in the environment of water flow impact or wind blowing, and prevents golden apple snails from escaping due to shaking. The multi-hole design of the connecting strip 14 can be adapted to various fixing methods such as expansion bolts and ropes, and is compatible with hard walls and soft soil environments, expanding the application scenarios.

[0032] In this embodiment, the upper end of the box body 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 to clean the golden apple snails inside.

[0033] Meanwhile, bait is placed inside the box 1 to improve the induction efficiency of golden apple snails into the box. 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
