Description

Technical Field

[0001] This utility model belongs to the field of agricultural pest control technology, specifically relating to a device for intercepting and trapping golden apple snails. Background Technology

[0002] Golden apple snails, as an invasive alien species, have caused serious damage to agricultural production and aquatic ecosystems. Their large-scale reproduction devours the stems and leaves of crops such as rice, leading to reduced yields. Currently, control methods for golden apple snails mainly include manual harvesting, chemical control, and biological control. However, manual harvesting is inefficient and costly; chemical control may pollute and harm the aquatic environment and other organisms; and biological control suffers from inconsistent effectiveness. Therefore, there is a need for an efficient, environmentally friendly, and easy-to-operate golden apple snail harvesting device. Utility Model Content

[0003] Based on the problems existing in the above-mentioned background technology, this utility model proposes a snail interception and trapping device, which solves the problems of low capture efficiency, water pollution and unstable biological control effect of existing snail control methods.

[0004] The embodiments of this utility model are implemented as follows:

[0005] This utility model provides a device for intercepting and trapping golden apple snails, which includes an interception net unit and a ground cage unit; the interception net unit includes at least two fixed posts, and an interception net body is arranged between the two fixed posts, wherein the mesh size of the interception net body is smaller than the body shape of the golden apple snail;

[0006] The ground cage unit includes multiple ground cage bodies disposed on one side of the main body of the interception net. The multiple ground cage bodies are arranged along the length direction of the main body of the interception net. Each ground cage body is a mesh box structure. A bait box is disposed inside the ground cage body. Multiple entrances communicating with the interior are disposed on the side of the ground cage body.

[0007] Furthermore, each of the aforementioned fixed piles is a rigid rod, and the bottom end of each fixed pile is a pointed cone structure with the tip pointing downwards.

[0008] Furthermore, the main body of the interception net is made of high-strength, corrosion-resistant flexible material, with a mesh size of 2cm to 3cm.

[0009] Furthermore, multiple first fixing rods are evenly spaced on one side of the main body of the interception net, with a spacing of 1m to 2m between adjacent first fixing rods.

[0010] Furthermore, each of the cage bodies is made of a high-strength, corrosion-resistant flexible material, and each cage body has a zipper at the top.

[0011] Furthermore, each of the aforementioned entrances is provided with a guide tube, each of the guide tubes is a mesh-like perforated design, each guide tube is a frustum structure, the large-diameter end of the guide tube is fixedly connected to the entrance, and the small-diameter end faces the interior of the ground cage body.

[0012] Furthermore, each of the two sides along the length of the main body of the fish trap is provided with a crossbar structure. Each crossbar structure includes two second fixed rods, which are located on both sides along the width of the main body of the fish trap. Two connecting rods are intersecting between the two second fixed rods, with their middle sections hinged together and their tops hinged to the tops of the two second fixed rods respectively. The bottoms of the two connecting rods are slidably connected to the lower middle parts of the two second fixed rods via sliding grooves, which are vertically arranged on the second fixed rods. The bottom end of each second fixed rod is a pointed cone structure with its tip pointing downwards. The crossbar structure enables the folding and storage of the main body of the fish trap, facilitating carrying and installation. When installing the main body of the fish trap, each second fixed rod is inserted into the bottom of the water area, increasing the stability of the main body of the fish trap.

[0013] Furthermore, in each of the crossbar structures, the second fixed rod closest to the main body of the interception net is fixedly connected to the first fixed rod.

[0014] In the interception net unit, the main body of the net is woven from a high-strength, corrosion-resistant flexible material (such as polyethylene), with a mesh size of 2cm to 3cm. This effectively blocks golden apple snails from passing through without obstructing water flow. The fixing stakes are rigid poles (such as stainless steel poles) used to vertically fix the main body of the net to the bottom of the water body and the bank, creating a continuous barrier in the water. In addition, multiple first fixing poles, made of lightweight, high-strength materials (such as carbon fiber or alloy poles), are installed at 1m to 2m intervals on the sides of the main body of the net. When the main body of the net is unfolded, the multiple first fixing poles work in conjunction with the fixing stakes to stabilize the net, ensuring it forms a continuous barrier perpendicular to the water body. The entire interception net unit is foldable for easy carrying and storage, and unfolds into a barrier when in use.

[0015] In the trap unit, the bait box contains attractants to attract golden apple snails. When the golden apple snails move in the water, they are blocked by the interception net unit. As the golden apple snails move along the main body of the interception net, they are attracted by the bait and enter the main body of the trap through the guide tube, thus being captured.

[0016] The zipper at the top of the trap allows for easy opening and closing of the trap, facilitating the replacement of bait and removal of the captured golden apple snails.

[0017] Compared with methods of controlling golden apple snails such as manual harvesting, chemical control, and biological control, the beneficial effects of this invention are:

[0032] Furthermore, the main body 102 of the interception net is made of a high-strength, corrosion-resistant flexible material, which can be polyethylene. The mesh size is 2cm to 3cm, which can block the passage of golden apple snails without affecting the flow of water.

[0033] Furthermore, multiple first fixing rods 103 are evenly spaced on one side of the interception net body 102, with a spacing of 1m to 2m between adjacent first fixing rods 103. When the interception net body 102 is deployed, the multiple first fixing rods 103 cooperate with the fixing stakes 101 to stabilize the interception net body 102.

[0034] Furthermore, each of the trap bodies 201 is made of a high-strength, corrosion-resistant flexible material, and each trap body 201 has a zipper 203 at its top. The trap body 201 is periodically opened through the zipper 203 to remove the captured golden apple snails and to replenish or replace the bait in the bait box.

[0035] Furthermore, each of the inlets 202 is provided with a guide tube 204. Each guide tube 204 is a mesh-like perforated structure and has a frustum shape.
