Description

Technical Field

[0001] The utility model relates to the field of biological trapping devices, in particular to a trap for laying eggs of golden apple snails. Background Art

[0002] The golden apple snail is gradually appearing in various parts of China. Due to its strong adaptability and rapid reproduction, it has become a highly harmful invasive species. It poses a serious threat to agriculture, ecology, and human health. Its strong resistance to pesticides and rapid reproduction have led to its rapid spread in many areas, causing significant damage to local ecosystems and agricultural production. Effective eradication of the golden apple snail is impossible. Utility Model Content

[0003] The utility model aims to provide a trap for laying eggs of golden apple snails, so as to solve the problems in the prior art that golden apple snails damage the ecological environment, are difficult to eliminate, are difficult to catch, and cannot control the reproduction speed of golden apple snails.

[0004] The embodiment of the present utility model is achieved as follows:

[0005] The embodiment of the utility model provides a golden apple snail spawning trap, which includes an spawning rod;

[0006] The oviposition rod is an elliptical cylindrical structure with two ends open. The oviposition rod has a front side and a back side. The front side of the oviposition rod is provided with a plurality of first spikes with large gaps and a plurality of second spikes with small gaps from bottom to top. The back side of the oviposition rod is provided with a plurality of third spikes with small gaps and a plurality of fourth spikes with large gaps from bottom to top. The lengths of the plurality of second spikes and the plurality of third spikes are greater than the lengths of the plurality of first spikes and the plurality of fourth spikes.

[0007] A cantilevered killing ring is provided between the plurality of the third spikes and the plurality of the fourth spikes on the reverse side, and one side of the killing ring is fixedly connected to the reverse side between the plurality of the third spikes and the plurality of the fourth spikes;

[0008] A net bag is provided at the bottom of the killing ring, and the opening of the net bag is fixedly connected to the lower edge of the killing ring.

[0009] When in use, first, during the spawning season of the golden apple snail, the bottom end of the above-mentioned spawning rod is inserted into the bottom of the water so that the upper part of the above-mentioned spawning rod is located above the water surface. According to the habits of the golden apple snail, the above-mentioned spawning rod will lure the golden apple snail to climb comfortably on the several above-mentioned first spikes on the front side. When the golden apple snail encounters several above-mentioned second spikes, the golden apple snail will move to several above-mentioned fourth spikes to lay eggs. After laying eggs, the golden apple snail will automatically fall down and fall into the net bag of the above-mentioned killing ring because it is exhausted in the climbing process. Secondly, several above-mentioned third spikes can prevent the golden apple snail from climbing from the above-mentioned reverse side. Finally, personnel remove the egg mass every two to three days for destruction. At the same time, the spawning apple snails in the net bag are collected and destroyed.

[0010] The apple snail spawning trap disclosed in this embodiment is cleverly designed with the several first spikes that are convenient for the apple snail to climb, so that the apple snail has to spend a lot of effort to climb the several first spikes with a longer distance. When the apple snail is blocked when moving to the several second spikes, the apple snail will move to the fourth spikes to lay eggs. After laying eggs, the apple snail will fall into the net bag. The egg masses are removed and destroyed every two to three days. At the same time, the egg-laying apple snails in the net bag are collected and destroyed. Not only the egg masses are killed, but the egg-laying apple snails are effectively killed after completing one spawning, thereby greatly reducing the egg-laying amount of the apple snail. The apple snail spawning trap has the beneficial effects of good capture effect, easy elimination, simple capture and the ability to control the reproduction rate of apple snails.

[0011] Optionally, several of the above-mentioned first spikes, several of the above-mentioned second spikes, several of the above-mentioned third spikes and several of the above-mentioned fourth spikes are evenly distributed into several layers along the circumferential direction of the above-mentioned ovipositing rod.

[0012] Such arrangement is conducive to the golden apple snail climbing the above-mentioned egg-laying pole according to its own egg-laying habit, thereby achieving capture.

[0013] Optionally: the gap between some of the above-mentioned first spikes and some of the above-mentioned fourth spikes is larger than the gap between some of the above-mentioned second spikes and some of the above-mentioned third spikes.

[0014] Such arrangement enables the golden apple snail to only climb upwards from the several first spikes, and be blocked when climbing to the several second spikes. Then, the golden apple snail will climb around the above-mentioned spawning rod and move to the several fourth spikes on the above-mentioned opposite side to lay eggs. After the golden apple snail finishes laying eggs, it will lose its center of gravity or fall naturally, and the golden apple snail will fall into the net bag below the above-mentioned killing ring. The several third spikes are small, which is conducive to preventing the golden apple snail from climbing upwards from the above-mentioned opposite side, so that it will not fall into the net bag.

[0015] Optionally, the length of the distribution area of the plurality of the first spikes on the front surface is greater than the length of the distribution area of the plurality of the second spikes;

[0016] The lengths of several of the third spike distribution areas on the reverse side are smaller than the lengths of several of the fourth spike distribution areas.

[0017] In this arrangement, the large distribution areas of the first spikes and the fourth spikes are intended to consume the physical strength of the golden apple snail, so that the golden apple snail does not have the physical strength to climb down along the spawning pole after laying eggs, thereby increasing the probability of the golden apple snail losing its center of gravity and falling naturally after laying eggs, thereby improving the capture effect, while the small distribution areas of the second spikes and the third spikes can not only prevent the golden apple snail from moving, but also reduce the equipment processing cost.

[0018] Optionally, a support column is provided at the bottom end of the egg-laying rod, and one end of the support column close to the egg-laying rod is fixedly connected to the bottom end of the egg-laying rod.

[0019] In this way, the support column can ensure that the trap can be firmly inserted into the bottom of the water and its entire structure can be completely extended out of the water. The unique design of the support column not only ensures the stability of the trap, but also fully utilizes the buoyancy of the water body, reducing the potential impact on the underwater ecological environment.

[0020] Optionally, the support column has an elliptical column at one end close to the egg-laying rod, and the area of the elliptical column is adapted to the end area of the egg-laying rod.

[0021] With such arrangement, the elliptical cylinder can provide a bearing platform for the egg-laying rod, so that the pressure on the egg-laying rod is evenly transferred to the support column through the elliptical cylinder.

[0022] Optionally, one end of the elliptical cylinder away from the egg-laying rod is fixedly connected to a cylinder, and one end of the cylinder away from the elliptical cylinder is fixedly connected to a cone.

[0023] With such arrangement, the arrangement of the cylinder and the cone facilitates the insertion of the trap into the water bottom.

[0024] Optionally: the net bag is made of high-strength material, and a tying wire is provided at the bottom end of the net bag, and the tying wire is detachably tied to the bottom end of the net bag.

[0025] With such arrangement, the net bag can be tied with the tying wires, so that the net bag can hold a number of apple snails, and the apple snails can be collected in a centralized manner by removing the tying wires, thereby improving the efficiency of catching apple snails.

[0026] Optionally, the outer surfaces of the above-mentioned support columns are all smooth surfaces.

[0027] Such an arrangement not only avoids accidental injury to aquatic plants and animals, but also facilitates the installation and disassembly of the device.

[0028] In summary of the above description, the golden apple snail spawning trap disclosed by the utility model has the beneficial effects of good capturing effect, easy elimination, simple capture and ability to control the reproduction speed of golden apple snails.

[0037] Example

[0038] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , this embodiment provides a golden apple snail spawning trap, comprising an spawning rod 1;

[0039] The egg-laying rod 1 is an elliptical cylindrical structure with openings at both ends. The egg-laying rod 1 has a front side 2 and a back side 3. The front side 2 of the egg-laying rod 1 is provided with a plurality of first spikes 4 with large gaps and a plurality of second spikes 5 with small gaps from bottom to top. The back side 3 of the egg-laying rod 1 is provided with a plurality of third spikes 6 with small gaps and a plurality of fourth spikes 7 with large gaps from bottom to top. The lengths of the plurality of second spikes 5 and the plurality of third spikes 6 are greater than the lengths of the plurality of first spikes 4 and the plurality of fourth spikes 7.

[0040] A cantilevered killing ring 8 is provided between the third and fourth spikes on the reverse side 3, and one side of the killing ring 8 is fixedly connected to the reverse side 3 between the third and fourth spikes;

[0041] A net bag is provided at the bottom of the killing ring 8 , and the opening of the net bag is fixedly connected to the lower edge of the killing ring 8 .

[0042] When in use, first, in the spawning season of the golden apple snail, the bottom end of the spawning rod 1 is inserted into the bottom of the water so that the upper part of the spawning rod 1 is located above the water surface. According to the habits of the golden apple snail, the spawning rod 1 will lure the golden apple snail to climb comfortably on the several first spikes 4 on the front side 2. When the golden apple snail encounters several second spikes 5, the golden apple snail will move to several fourth spikes 7 to lay eggs. After laying eggs, the golden apple snail is exhausted in the climbing process. At this time, the golden apple snail automatically falls down and falls into the net bag of the killing ring 8. Secondly, the several third spikes 6 can prevent the golden apple snail from climbing from the back side 3. Finally, the personnel remove the egg mass every two to three days for destruction. At the same time, the spawning apple snails in the net bag are collected and destroyed.

[0043] The apple snail spawning trap disclosed in this embodiment is cleverly designed with several first spikes 4 that are convenient for the apple snail to climb, so that the apple snail spends a lot of effort to climb the several first spikes 4 with a longer distance. When the apple snail is blocked when moving to several second spikes 5, the apple snail will move to the fourth spike 7 to lay eggs. After laying eggs, the apple snail will fall into the net bag. The egg mass is removed and destroyed every two to three days. At the same time, the egg-laying apple snails in the net bag are collected and destroyed. Not only the egg mass is killed, but the egg-laying apple snails are effectively killed after completing one spawning, thereby greatly reducing the egg-laying amount of the apple snail. The apple snail spawning trap has the beneficial effects of good capture effect, easy elimination, simple capture and the ability to control the reproduction rate of the apple snail.

[0044] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the golden apple snail spawning trap can effectively induce the golden apple snail to climb up the spawning pole 1 and lay eggs at a preset position, and then use the killing ring 8 and the matching net bag to capture it. This environmentally friendly and efficient killing method not only reduces the damage of the golden apple snail to the local ecological environment, but also avoids the side effects and pollution problems that may be caused by traditional chemical methods.

[0045] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 Several first spikes 4, several second spikes 5, several third spikes 6 and several fourth spikes 7 are evenly distributed in several layers along the circumferential direction of the egg-laying rod 1. This is conducive to the golden apple snail climbing the egg-laying rod 1 according to its own egg-laying habits, thereby achieving capture.

[0046] The gap between the first spikes 4 and the fourth spikes 7 is larger than the gap between the second spikes 5 and the third spikes 6. This arrangement allows the apple snail to only climb upward from the first spikes 4. The apple snail will be blocked when it climbs to the second spikes 5. Then, the apple snail will climb around the spawning rod 1 and move to the fourth spikes 7 on the back side 3 to lay eggs. After laying eggs, the apple snail will lose its center of gravity or fall naturally, and the apple snail will fall into the net bag below the killing ring 8. The small size of the third spikes 6 is conducive to preventing the apple snail from climbing upward from the back side 3, so that it will not fall into the net bag.

[0047] The length of the distribution area of several first spikes 4 on the front side 2 is greater than the length of the distribution area of several second spikes 5; the length of the distribution area of several third spikes 6 on the back side 3 is less than the length of the distribution area of several fourth spikes 7. The large distribution areas of several first spikes 4 and several fourth spikes 7 are intended to consume the physical strength of the golden apple snail, so that the golden apple snail has no physical strength to climb down along the spawning pole 1 after laying eggs, thereby increasing the probability of the golden apple snail losing its center of gravity and falling naturally after laying eggs, thereby improving the catching effect. The small distribution areas of several second spikes 5 and several third spikes 6 can not only prevent the golden apple snail from moving, but also reduce the equipment processing cost.

[0048] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A support column 9 is provided at the bottom end of the spawning rod 1. One end of the support column 9 close to the spawning rod 1 is fixedly connected to the bottom end of the spawning rod 1. The support column 9 can ensure that the trap can be firmly inserted into the bottom of the water and its overall structure is completely extended out of the water. The unique design of the support column 9 not only ensures the stability of the trap, but also makes full use of the buoyancy of the water body, reducing the potential impact on the underwater ecological environment.

[0049] The support column 9 has an elliptical cylinder 10 at one end close to the egg-laying rod 1. The area of the elliptical cylinder 10 is adapted to the end area of the egg-laying rod 1. The elliptical cylinder 10 can provide a bearing platform for the egg-laying rod 1 so that the pressure on the egg-laying rod 1 is evenly transferred to the support column 9 through the elliptical cylinder 10.

[0050] The end of the elliptical cylinder 10 away from the spawning rod 1 is fixedly connected to the cylinder 11, and the end of the cylinder 11 away from the elliptical cylinder 10 is fixedly connected to the cone 12. The arrangement of the cylinder 11 and the cone 12 facilitates the insertion of the trap into the water bottom.

[0051] The net bag is made of high-strength material, and a tying wire is provided at the bottom of the net bag. The tying wire can be detachably tied to the bottom of the net bag. By tying the net bag with the tying wire, the net bag can hold a number of apple snails, and the apple snails can be collected in a centralized manner by disassembling the tying wire, thereby improving the efficiency of catching apple snails.

[0052] The outer surfaces of the support columns 9 are all smooth surfaces, which not only avoids accidental damage to aquatic plants and animals, but also facilitates the installation and disassembly of the device.

[0053] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the spawning rod 1 is the core part of the trap. The spawning rod 1 is 50 cm long and is designed to take advantage of the habit of the golden apple snail to crawl out of the water to lay eggs. The length of the first spikes 4 and the fourth spikes 7 on its surface is 5 mm, and the length of the second spikes 5 and the third spikes 6 are 1 mm. They are carefully arranged on both sides to form a unique climbing guide path; the second spikes 5 on the front side 2 are arranged in the upper 21 cm area of the spawning rod 1 to prevent the golden apple snail from climbing directly to the top; and the first spikes 4 on the front side 2 are arranged in the lower 29 cm area of the spawning rod 1 to prevent the golden apple snail from climbing directly to the top. The snail can continue to crawl upwards more comfortably; when the apple snail reaches the middle of the spawning pole 1, the 1 mm first spike 4 and the fourth spike 7 on the front side 2 and the back side 3 overlap to form a ring part, which cleverly guides the apple snail to move to the back side 3 to lay eggs; the killing ring 8 is a detachable elliptical ring structure with a diameter of 24 cm and a width of 21 cm. The killing ring 8 is cleverly designed. It is not only the key to capturing apple snails, but also equipped with a net bag for finally collecting the apple snails that fall into it. Once the apple snails complete spawning and lose their center of gravity or fall naturally, they will be captured by this clever killing ring 8 and the net bag below.

[0054] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4In this embodiment, the elliptical column 10 of support column 9 is 1 cm long, the cylindrical body 11 is 15 cm long, and the conical body 12 is 4.5 cm long. These three elements are tightly integrated, ensuring that the trap is firmly inserted into the waterbed and fully extends above the surface. The unique design of support column 9 not only ensures the stability of the trap, but also fully utilizes the buoyancy of the water, reducing potential impacts on the underwater ecosystem.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
