Description

Technical Field

[0001] This utility model relates to the field of trapping devices, and in particular to a device for attracting and cleaning up the eggs of golden apple snails. Background Technology

[0002] Golden apple snails, as an invasive alien species, not only cause serious harm to farmland ecosystems, but also, if ingested undercooked snails, can lead to parasitic infections, causing illness or even death. Currently, there are various control methods, including chemical, biological, and physical control, each with its own advantages and disadvantages. Chemical control involves applying chemicals to areas where golden apple snails are rampant to effectively kill them; however, over-reliance on chemical control can damage the ecological environment. Biological control relies on poultry such as chickens and ducks preying on the snails to reduce their numbers, but so far no natural predators have been found, therefore this method is not effective in controlling the spread of golden apple snails. Physical control involves manually collecting golden apple snails or their eggs using capture devices for centralized extermination. Chinese patent application CN220756210U discloses a low-cost net-post trapping device for attracting golden apple snails to feed and lay eggs. The device includes a support post, a trapping post, and a lifting line. The trapping post is equipped with an egg-scraping component and a capture component. The egg-scraping component is an inner ring made of iron wire, the diameter of which matches the outer diameter of the trapping post. One end of the lifting line is fixedly connected to the inner ring, and the other end is fixedly connected to the top of the support post. The golden apple snail egg mass is scraped off by lifting the iron wire ring through the lifting line. After scraping the eggs once, the inner ring cannot be reset by the lifting line and needs to be manually reset, which is difficult and has low cleaning efficiency. Summary of the Invention

Detailed Implementation

[0026] 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.

[0027] The purpose of this invention is to provide a device for attracting and cleaning up golden apple snail eggs, in order to solve the problems existing in the prior art. The device is easy to operate and can improve the cleaning efficiency of golden apple snail egg masses.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figures 1-7 The present invention will be further described in detail below with reference to specific embodiments.

[0029] This utility model provides a device for attracting and cleaning up the eggs of golden apple snails, such as... Figures 1-3As shown, the device includes an egg-laying device, a cleaning rod 1, and an attractant container 2. The outer wall of the egg-laying device provides a location for golden apple snails to lay eggs. The cleaning rod 1 is connected to an egg scraper, one side of which is designed to fit against the outer wall of the egg-laying device. The cleaning rod 1 can move relative to the egg-laying device and move the egg scraper along the outer wall of the egg-laying device to scrape off the golden apple snail egg masses attached to the outer wall. The attractant container 2 is used to hold the attractant and can be fixed to the cleaning rod 1. By placing the attractant in the attractant container 2 to attract golden apple snails to lay eggs on the egg-laying device, and then using the cleaning rod 1 to move the egg scraper along the outside of the egg-laying device, the golden apple snail egg masses can be scraped off. The device is simple to operate. Compared with the existing technology, which requires pulling a lifting line to scrape off the golden apple snail egg masses and manually resetting the egg scraper, pushing the cleaning rod 1 to move the egg scraper to scrape off the golden apple snail egg masses and then pulling the cleaning rod 1 to reset the egg scraper makes the operation convenient and quick. Furthermore, if a single cleaning session fails to completely remove the golden apple snail egg mass, the egg scraper can be used by repeatedly pushing and pulling the cleaning rod 1 to scrape off the egg mass, thereby improving the cleaning efficiency. Moreover, the golden apple snail egg-laying attraction and cleaning device provided by this invention can be reused after each use by replacing the attractant, effectively reducing the cost of capturing golden apple snail eggs.

[0030] In some embodiments of this invention, the oviposition device includes a fixing device 3 and multiple oviposition rods 4 distributed around the fixing device 3. The top end of each oviposition rod 4 is fixedly connected to the fixing device 3. The fixing device 3 has a through hole through which a cleaning rod 1 passes. The first end of the cleaning rod 1 is located within the space enclosed by the oviposition rods 4, and the second end of the cleaning rod 1 is located outside the space enclosed by the oviposition rods 4. The attractant container 2 is fixed to the first end. Distributing the oviposition rods 4 evenly around the fixing device 3 creates a circumference of oviposition positions, providing a large area for oviposition and enhancing the effectiveness of the golden apple snail oviposition attraction and cleaning device. The fixing device 3 can have various shapes, such as rings or polygons, to support and fix the oviposition rods 4. In other embodiments, the oviposition device can also be cylindrical or other shapes.

[0031] In some embodiments of this invention, the egg scraper includes multiple egg-scraping plates 5 arranged around the egg-laying device. The number of egg-scraping plates 5 is the same as the number of egg-laying rods 4. Each egg-scraping plate 5 is fixedly connected to a cleaning rod 1 via a connector 6. The connector 6 passes through the egg-laying device and is movable relative to it. The movement of the cleaning rod 1 can cause each egg-scraping plate 5 to move along the outer wall of the egg-laying rod 4. In this embodiment, the connector 6 is a connecting rod, and a gap is provided on the egg-laying rod 4 for the connecting rod to pass through. The connecting rod passes through the gap and is fixedly connected to the egg-scraping plate 5. In other embodiments, the connecting rod is fixedly connected to any point on the centerline of the egg-scraping plate 5, which makes the egg-scraping plate 5 more stable and less prone to damage during up-and-down movement. In other embodiments, the connecting rod can also pass through the gap between two adjacent egg-laying rods 4 and connect to the egg-scraping plate 5. The spacing between adjacent egg-laying rods 4 and the width of the gaps are recommended to be less than or equal to 3mm. This prevents the golden apple snail from crawling into the inner side of the device to lay eggs, fixing the egg-laying position of the golden apple snail on the outer wall of the egg-laying rod 4, making it easier for the egg-scraping plate 5 to scrape off the golden apple snail egg masses. In addition, the first end of the cleaning rod 1 is inside the space enclosed by the egg-laying rods 4, and the connecting rod passes through the gap on the egg-laying rod 4 and connects to the egg-scraping plate 5, which can also provide a certain support effect for the egg-laying rods 4, making the egg-laying rods 4 less prone to shaking, and making the entire device more stable and reliable. In some other embodiments, the egg scraper can also be set as a ring, with several connecting rods fixedly connected to the ring-shaped egg scraper.

[0032] In some embodiments of this invention, the outer wall surface of the ovipositor 4 is a concave arc surface. Setting the ovipositor 4 as a concave arc surface further increases the area available for the golden apple snail to lay eggs, thereby enhancing the effectiveness of the ovipositor attraction and cleaning device. In other embodiments, the ovipositor 4 can also be a rectangular rod, or other shapes that facilitate the crawling and egg-laying of the golden apple snail.

[0033] In some embodiments of this invention, the golden apple snail egg-laying attraction and cleaning device further includes a reinforcing device 7, which is fixedly connected to the rod body of each egg-laying rod 4 in the circumferential direction. By fixing the reinforcing device 7 to the egg-laying rod 4 in the circumferential direction, the entire device becomes more stable and reliable. The reinforcing device 7 can be a ring or other structure that facilitates the circumferential fixing of the egg-laying rod 4. The reinforcing device 7 is positioned below the fixing device 3 and does not affect the vertical movement of the egg-scraping plate 5.

[0034] In some embodiments provided by this utility model, such as Figures 4-6As shown, the cleaning rod 1 has a movable space inside, and a positioning buckle 8 is installed inside the movable space. One end of the positioning buckle 8 can extend or retract from the cleaning rod 1. When one end of the positioning buckle 8 extends from the cleaning rod 1, it can abut against the outer edge of the through hole to restrict the movement of the cleaning rod 1 relative to the egg-laying device. When the positioning buckle 8 retracts into the cleaning rod 1, the cleaning rod 1 can move up and down relative to the fixing device 3 through the hole. When the device induces golden apple snails to lay eggs, pushing the positioning buckle 8 restricts the movement of the cleaning rod 1 relative to the egg-laying device. At this time, the position of the cleaning rod 1 is fixed, and the device is in the state of inducing golden apple snails to lay eggs. By fixing the position of the cleaning rod 1 and keeping the attractant container 2 above the water surface, water can be prevented from entering the attractant container 2 and affecting the effectiveness of the attractant. When it is necessary to scrape off the golden apple snail egg masses, one end of the positioning buckle 8 retracts into the cleaning rod 1, and the cleaning rod 1 can move up and down relative to the fixing device 3. By operating the cleaning rod 1 to move up and down, the egg scraping plate 5 scrapes off the golden apple snail egg masses. The device has a simple structure and is easy to operate.

[0035] In some embodiments of this utility model, the positioning buckle 8 includes a positioning plate 82, an upper pin 81, and a lower pin 83. The upper pin 81 and the lower pin 83 are respectively fixed on two opposite sides of the positioning plate 82, with the upper pin 81 fixed to the upper end of the positioning plate 82 and the lower pin 83 fixed to the lower end of the positioning plate 82. The cleaning rod 1 has an upper pin hole 11 and a lower pin hole 12. The upper pin 81 extends out of the upper pin hole 11. Pushing the upper pin 81 allows the lower pin 83 to extend out of the lower pin hole 12 from inside the cleaning rod 1 and abut against the outer edge of the through hole to restrict the movement of the cleaning rod 1. The overall structure of the positioning buckle 8 and the structure that cooperates with the cleaning rod 1 are simple and easy to manufacture. Pulling the cleaning rod 1 and pushing the upper pin 81, the cleaning rod 1 is positioned by the abutment of the lower pin 83 and the through hole. The operation is simple and easy to implement. In some other embodiments, the upper pin 81 and the lower pin 83 are fixed horizontally to the positioning plate 82, making the movement of the positioning buckle 8 smoother. Since the golden apple snail lays its eggs at a height of 15mm to 40mm above the water surface, in order to keep the attractant above the water surface while not hindering the golden apple snail from crawling on the egg-laying rod 4, the position of the egg-scraping plate 5 should be at the uppermost end of the gap when the movement of the cleaning rod 1 is restricted. Therefore, the initial position of the egg-scraping plate 5 should be set at least 45mm above the water surface. The length of the egg-laying rod 4 and the position of the egg-scraping plate 5 when the movement of the cleaning rod 1 is restricted can be set according to the actual situation.

[0036] In some embodiments provided by this utility model, such as Figure 7As shown, the attractant container 2 is also provided with an attractant inlet 21, and a movable door 22 is provided at the attractant inlet 21. The movable door 22 can move relative to the attractant container 2, and can close or open the attractant inlet 21. Several through holes 23 are formed on the wall of the attractant container 2. By providing the movable door 22, it is convenient to replace the attractant for reuse. By providing through holes 23 on the wall of the attractant container 2, the attractant can also be easily dispersed to the outside, attracting golden apple snails to lay eggs. The connection between the movable door 22 and the attractant container 2 can be a sliding connection, a hinge, or other means that facilitate the opening and closing of the movable door 22, so as to place the attractant.

[0037] In some embodiments of this utility model, a connecting platform 13 is fixedly provided at the bottom of the cleaning rod 1. The side of the connecting platform 13 is detachably connected to the connecting piece 6, and the bottom surface of the connecting platform 13 is detachably connected to the attractant container 2. The connecting piece 6 is detachably connected to the egg scraping plate 5. The connecting rod and the connecting platform 13, as well as the connecting rod and the egg scraping plate 5, are all designed to be detachably connected, which facilitates the replacement of the connecting rod or the egg scraping plate 5 when it is damaged. Compared with the need to replace the entire golden apple snail egg-laying attraction and cleaning device when it is damaged, the maintenance cost of the device is reduced. In this embodiment, the connecting rod and the connecting platform 13, as well as the connecting rod and the egg scraping plate 5, are all connected by a snap-fit ​​connection. Through holes can be opened on the connecting platform 13 to snap the connecting rod and the attractant container 2. The cross-section of the connecting platform 13 is larger than that of the cleaning rod 1. By fixing the connecting platform 13 at the bottom of the cleaning rod 1, rather than connecting directly from the cleaning rod 1, the cleaning rod 1 is prevented from breaking during use due to too many openings, and the service life of the cleaning rod 1 can also be extended. The attractant container 2 is detachably connected to the connecting platform 13. After each use, the device can be reused by replacing the attractant, effectively reducing the cost of capturing golden apple snail eggs. In some other embodiments, a rotating buckle is provided on the attractant container 2 to engage with the connecting platform 13, resulting in a simple structure that is easy to manufacture. In other embodiments, other detachable connection methods, such as screw connections, can also be used between the connecting rod and the connecting platform 13, the connecting rod and the egg scraper 5, and the attractant container 2 and the connecting platform 13.

[0038] In some embodiments of this invention, the lower end of the spawning rod 4 is configured as a sloping surface with a sharp angle, so that the lower end of the spawning rod 4 can be inserted into the soil or riverbed. By configuring the spawning rod 4 as a sloping surface with a sharp angle, the entire device can be fixed by inserting it downwards into the soil or riverbed. The fixing structure is simple and easy to manufacture. When it is necessary to scrape off the golden apple snail eggs, the entire device can be pulled out to perform the scraping operation.

[0039] In some embodiments of this invention, the golden apple snail egg-laying attraction and cleaning device is made entirely of a corrosion-resistant and environmentally friendly material, specifically PVC (polyvinyl chloride), which can be reused multiple times, reducing the cost of capturing golden apple snail eggs. Furthermore, the golden apple snail has a long egg-laying period, from April to October each year, and the device does not pollute water bodies, allowing for long-term use in farmland or riverbanks. The device can also be made of other environmentally friendly materials, such as PP (polypropylene).

[0040] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
