Description

Technical Field

[0001] This utility model relates to the field of golden apple snail control technology, specifically a 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 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 golden apple snail trapping box, comprising a main box and a secondary box, wherein the secondary box is disposed at the bottom of the main box and extends upward into the interior of the main box; the bottom of the main box has a plurality of first snail inlets surrounding the secondary box; and the side wall of the secondary box has a plurality of second snail inlets; each of the first and second snail inlets is provided with an anti-escape component; the anti-escape component includes a plurality of rotatable levers arranged in a row, each lever having a first position and a second position. In the first position, the stop bar blocks either the first or second inlet and can rotate unidirectionally inward under the action of an external force from the outside to the inside. When the stop bar 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 can be placed in places with a large number of golden apple snails. It adopts a double-layer structure of a main box and a secondary box, both of which are equipped with inlets. It can attract and capture a large number of golden apple snails. The anti-escape component at the inlet can prevent the golden apple snails that have entered the box from escaping again, which greatly improves the trapping efficiency, has no environmental pollution or damage, and has low labor costs.

[0005] Preferably, the anti-escape component further includes a pair of pivot seats, with a pivot connected between the pivot seats. The first end of the stop lever is sleeved on the pivot. The pivot seats can support the pivot, and the stop lever can rotate freely on the pivot 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 stop is provided laterally between the rotating shaft seats. When the stop bar contacts the limit stop, it is in the first position. When the stop bar is in the first position, the distance between its first end and the first or second threaded inlet is less than the distance between its second end and the first or second threaded inlet. The limit stop 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 stop.

[0008] Preferably, the side of the first screw inlet near the second end of the stop bar is the outer wall of the sub-box, so that the apple snails that have not crawled into the second screw inlet can smoothly crawl into the first screw inlet.

[0009] Preferably, the first and / or second inlet screw inlets are provided with inwardly extending side baffles on both sides of the lateral direction, which can guide the crawling of the golden apple snail and place it at the position of the first and second inlet screw inlets to block the screw inlets.

[0010] Preferably, the bottom plate of the sub-box is provided with perforated holes to facilitate cleaning of the interior of the sub-box and to facilitate the downward diffusion of the bait's scent.

[0011] Preferably, the upper part of the main box is provided with an openable box cover, and the side of the box cover is equipped with a locking part, which makes it convenient for staff to open the box cover to clean the golden apple snails inside.

[0012] Preferably, bait is placed inside the main box and / or the secondary box to improve the induction efficiency of golden apple snails into the box.

[0013] Preferably, both the main housing and the auxiliary housing are rectangular or square housings, which facilitates the setting of the first and second screw inlets.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The trapping box can be placed in areas with a high concentration of golden apple snails. It features a double-layered structure with a main box and a secondary box. Both the main box and the secondary box have multiple snail inlets, which can attract and capture a large number of golden apple snails. The escape prevention components at the snail inlets prevent the golden apple snails that have entered the box from escaping again, greatly improving the trapping efficiency. It causes no environmental pollution or damage and has low labor costs. Attached Figure Description

[0017] 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.

[0018] This utility model addresses the technical problems existing in current methods for controlling the population of golden apple snails. For example... Figure 1-4As shown, the following technical solution is provided: a golden apple snail trapping box, comprising a main box body 1 and a secondary box body 6, wherein the secondary box body 6 is disposed at the bottom of the main box body 1 and extends upward into the interior of the main box body 1; the bottom of the main box body 1 is provided with a plurality of first snail inlets 10 around the secondary box body 6; the side wall of the secondary box body 6 is provided with a plurality of second snail inlets 12; and an anti-escape component 5 is provided inside the first snail inlets 10 and the second snail inlets 12. The anti-escape component 5 includes a plurality of rotatable baffles 53 arranged in a row, each baffle 53 having a first position and a second position. In the first position, the stop lever 53 blocks the first screw inlet 10 or the second screw inlet 12 and can rotate unidirectionally inward under the action of an external force from the outside to the inside. When the stop lever 53 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 can be placed in places with a large number of golden apple snails. It adopts a double-layer structure of main box 1 and auxiliary box 6, both of which are equipped with screw inlets. It can attract and capture a large number of golden apple snails. The anti-escape component at the screw inlet can prevent the golden apple snails that have entered the box from escaping again, which greatly improves the trapping efficiency, has no environmental pollution or damage, and has low labor costs.

[0019] Specifically, the secondary box 6 is nested at the bottom of the main box 1 and extends upwards, forming a double-layer structure in which the outer box surrounds the inner box. The first screw inlet 10 at the bottom of the main box 1, which is set around the secondary box, and the second screw inlet 12 on the side wall of the secondary box 6 form a three-dimensional trapping network, allowing the golden apple snail to enter through two paths: crawling along the ground at the bottom and climbing vertically from the side. The trapping coverage area is more than doubled compared to a single-layer structure.

[0020] In addition, the main box 1 and the auxiliary box 6 form an independent trapping chamber. When the main box has a large catch, the golden apple snails can enter the inner chamber through the snail inlet of the auxiliary box, avoiding the snails from accumulating and blocking the inlet due to overcrowding in a single space. The average daily catch per device has increased from 300 to more than 500.

[0021] In this embodiment, the first snail inlet 10 at the bottom of the main box 1 is arranged around the outside of the secondary box, with a quantity of 4-8, forming a ring-shaped entrance. This is adapted to the characteristic of golden apple snails crawling around the field surface, and avoids missed capture due to a single entrance.

[0022] In this embodiment, the anti-escape component 5 further includes a pair of pivot seats 54, with a pivot 55 connected between the pivot seats 54. The first end of the stop lever 53 is sleeved on the pivot. The pivot seats 54 can support the pivot, and the stop lever 53 can rotate freely on the pivot 55 without interfering with each other.

[0023] Specifically, the stop lever 53 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 53 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 its 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.

[0024] In this embodiment, the upper end of the stop lever 53 is connected to a bushing 51, which is sleeved on the rotating shaft 55. The bushing 51 and the stop lever 51 can be detachably connected (e.g., by 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 53 and the rotating shaft 55 simpler and more reasonable. The cooperation between the rotating shaft seat 54 and the bushing 51 enables the stop lever to rotate with low friction, ensuring that the apple snail can open the channel with minimal thrust, thus improving entry efficiency.

[0025] In this embodiment, a limiting block 52 is laterally arranged between the rotating shaft seats 55. When the stop lever 53 contacts the limiting block 52, it is in the first position. When the stop lever 53 is in the first position, the distance between its first end and the first screw inlet 10 or the second screw inlet 12 is less than the distance between its second end and the first screw inlet 10 or the second screw inlet 12. The limiting block 52 ensures that the stop lever can only rotate from the outside to the inside when it is in the first position. Each stop lever 53 can be limited by the limiting block 52. Specifically, the limiting block 52 precisely limits the swing boundary of the stop lever in the first position, so that the stop lever 53 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 52 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.

[0026] In this embodiment, the side of the first inlet 10 near the second end of the stop bar 53 is the outer wall of the sub-box 6, so that the golden apple snails that have not crawled into the second inlet 12 can smoothly crawl into the first inlet 10, reducing the missed catch rate to below 8%.

[0027] In this embodiment, both sides of the first screw inlet 10 and / or the second screw inlet 12 are provided with inwardly extending side baffles 7, which can guide the crawling of the golden apple snail and place it at the position of the first screw inlet 10 and the second screw inlet 12 to block the screw inlet. In addition, a slot 9 can be provided on the side baffle 7, and a rubber band or pull rope can be provided between the two slots 9. The purpose is to limit the extreme position of the inward rotation of the stop lever 53. The rubber band can also allow the stop lever 53 to be reset better.

[0028] In this embodiment, the bottom plate of the secondary enclosure 6 is evenly distributed with perforated holes 13, which facilitates cleaning of the interior of the secondary enclosure 6 and also facilitates the downward diffusion of the scent of the bait 8. Specifically, the diameter of the perforated holes 13 is designed to be 3-5mm, and the number is one per 10cm² of the bottom plate area, allowing the scent of the bait to diffuse downward through the water medium, attracting the snails at the bottom, and increasing the scent diffusion speed by 50%. In addition, the perforated holes 13 can allow the deposited silt and snail feces to be discharged with the water flow, avoiding the accumulation of dirt in the secondary enclosure 6 and affecting the trapping effect. The cleaning frequency is extended from once a week to once a month, and the maintenance cost is reduced by 70%.

[0029] In this embodiment, the upper end of the main 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 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.

[0030] In this embodiment, bait 8 is placed inside the main box 1 and / or the auxiliary box 6, which can improve the induction efficiency of golden apple snails into the box. The bait 8 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.

[0031] In this embodiment, both the main box 1 and the auxiliary box 6 are rectangular or square boxes, which facilitates the setting of the first screw inlet 10 and the second screw inlet 12. Rectangular or square boxes are also convenient for stacking, transportation and storage.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.
