[0002] Rice-loach co-cultivation is an effective way to achieve green farming in multiple seasons throughout the year. Rice paddies provide abundant natural bait for loaches. Loaches can loosen the mud in rice paddies and prey on pests, which is beneficial to rice growth and reduces pest damage, playing a part in biological pest control, saving pesticides, and improving grain quality. However, existing traps lack scientific bait fixing devices, resulting in the bait not being evenly distributed in the trap and the attraction effect being unstable. Especially in the shallow water environment of rice paddies, unfixed bait is easily drifted by the water flow, seriously affecting the trapping effect. In addition, the loach trap opening of traditional traps is usually sealed by tying knots in ropes. When collecting loaches, it is necessary to repeatedly untie and tie knots, which is cumbersome. Especially in the muddy environment of rice paddies, the ropes are easily contaminated with mud and water, further increasing the difficulty of operation. Therefore, there is an urgent need for a rice paddy loach trap trapping device. Utility Model Content

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-5 As shown, this specific embodiment adopts the following technical solution: It includes an outer net cylinder 1 and a support frame 18. Several support frames 18 are fixedly installed inside the outer net cylinder 1. The outer net cylinder 1 is a flat, long cylindrical structure, which can not only adapt to the shallow water environment of the paddy field, but also avoid the outer net cylinder 1 being too high and damaging the seedlings. A second connecting rope 16 is provided on the upper front side of the outer net cylinder 1, and a float 17 is fixedly installed at one end of the second connecting rope 16. Through the cooperation of the second connecting rope 16 and the float 17, it is possible for workers to accurately find the outer net cylinder 1 in the paddy field, and avoid the outer net cylinder 1 being completely submerged in water and difficult to find.

[0028] It also includes:

[0029] A first connecting rope 2 is fixedly installed on the front side of the outer net cylinder 1. A fixing nail 3 is fixedly installed at one end of the first connecting rope 2. Several loach inlet net cylinders 4 are provided on the left and right side walls of the outer net cylinder 1. A loach outlet 5 is provided on the rear side of the outer net cylinder 1.

[0030] A connecting ring 6, comprising several rings, is fixedly installed in several discharge ports opened at the top of the outer mesh cylinder 1. A rotating cover 7 is rotatably installed inside the connecting ring 6 via a thread. A bait box 8 is abutted against the bottom of the rotating cover 7. The connecting ring 6 is sleeved on the bait box 8. Several limiting grooves 14 are opened at the rounded corners of the upper lip of the bait box 8. Limiting blocks 15 are movably abutted against in the limiting grooves 14 and are fixedly installed inside the connecting ring 6. The limiting blocks 15 can provide a limiting effect on the installation of the bait box 8 on the connecting ring 6, thereby improving the stability of the installation of the bait box 8 on the connecting ring 6. A rotating handle 13 is provided in the groove opened at the top of the rotating cover 7. The side wall of the rotating handle 13 is provided with anti-slip texture. Through the cooperation of the rotating handle 13 and the anti-slip texture, the personnel can better apply force when rotating the rotating cover 7, thereby improving the convenience of rotating the rotating cover 7.

[0031] Two connecting half-rings 9 are fixedly installed on the rear side of the left and right side walls of the outer mesh cylinder 1, respectively. The two connecting half-rings 9 are connected by the mesh opening closing mechanism 10.

[0032] The network port sealing mechanism 10 includes:

[0033] Connecting blocks 10-1, there are four connecting blocks 10-1, which are fixedly installed on the upper and lower sides of the two connecting half rings 9 respectively, and the connecting blocks 10-1 on the left and right sides are arranged to abut against each other;

[0034] Two rotating rods 10-2 are respectively rotatably mounted on two right-side connecting blocks 10-1 via bearings. An adjustment handle 10-3 is fixedly installed at the right end of the rotating rod 10-2 at the right side position of the right-side connecting block 10-1. Insert rods 10-4 are fixedly installed on the side wall of the right-side connecting block 10-1 at both the front and rear sides of the rotating rod 10-2. The insert rods 10-4 are movably mounted in the through holes 10-5 opened on the left-side connecting block 10-1.

[0035] Two limiting plates 10-6 are respectively movably abutting against the left side walls of the two left connecting blocks 10-1. The left end of the rotating rod 10-2 passes through the matching slot 10-7 opened on the left connecting block 10-1 and is fixedly connected to the limiting plate 10-6. The limiting plate 10-6 and the matching slot 10-7 are configured to cooperate. A positioning block 11 is fixedly set on the left side wall of the adjusting handle 10-3. The positioning block 11 is movably set in the arc-shaped groove 12 opened on the right side wall of the right connecting block 10-1. Through the cooperation of the positioning block 11 and the arc-shaped groove 12, the rotation angle of the adjusting handle 10-3, the rotating rod 10-2 and the limiting plate 10-6 can be limited, and the alignment process of the limiting plate 10-6 and the matching slot 10-7 is more convenient.

[0036] There are four No. 1 magnets 10-8, which are fixedly installed on the left side of the inside of the four insert rods 10-4 respectively. No. 2 magnets 10-9 are fixedly installed on both the front and rear sides of the inside of the limiting plate 10-6. The No. 1 magnets 10-8 and No. 2 magnets 10-9 are attracted to each other. With the cooperation of the mesh closure mechanism 10, the opening and closing of the loach outlet 5 can be achieved without repeatedly untying and tying on the back side of the outer mesh cylinder 1, making it more convenient to collect loaches.

[0037] When using this invention, the bait box 8 is placed against the connecting ring 6, and the solid slow-release loach bait block is placed inside the bait box 8. The rotating cover 7 is then screwed onto the connecting ring 6. The outer net cylinder 1 is then placed in the paddy field, and ground stakes are inserted into the soil for fixation. The loaches, attracted by the solid slow-release loach bait block, swim from the inlet net cylinder 4 into the outer net cylinder 1. When it is time to collect the loaches, the ground stakes are pulled out of the soil, and the outer net cylinder 1 is removed from the paddy field. Then, the adjusting handle 10-3 is rotated, causing the rotating rod 10-2 to rotate. The rotating rod 10-2 causes the limiting plate 10-6 to rotate to a vertical position, aligning the limiting plate 10-6 with the fitting through groove 10-7. This allows the two connecting half-rings 9 to be separated. This opens the loach outlet 5, allowing the loach to be poured out of the outer net cylinder 1. When it is necessary to close the loach outlet 5, all the netting around the loach outlet 5 on the outer net cylinder 1 is gathered inside the two connecting half-rings 9 and brought into contact with each other, so that the insertion rod 10-4 passes through the through hole 10-5 and the limiting plate 10-6 passes through the fitting through groove 10-7. Then, the adjusting handle 10-3 is rotated, causing the rotating rod 10-2 to drive the limiting plate 10-6 to rotate to a horizontal state. The attraction between the first magnet 10-8 and the second magnet 10-9 is used to limit the horizontal state of the limiting plate 10-6, preventing the limiting plate 10-6 from flipping over at will. At this time, the loach outlet 5 is closed.

[0038] Compared with the prior art, the beneficial effects of this utility model are:

[0039] The outer net cylinder 1 adopts a flat and long cylindrical structure, which is perfectly adapted to the shallow water environment of the paddy field, avoiding damage to the rice seedlings, while ensuring that the loach can enter smoothly and improving the trapping efficiency.

[0040] By rotating the cover 7 and connecting ring 6 with their threads, the bait box 8 can be securely installed, ensuring that the bait is evenly distributed in the outer net cylinder 1, improving the attraction effect, and making it easy to replace the bait. The operation is simple and efficient.

[0041] The float 17, in conjunction with the connecting rope, facilitates quick positioning of the trap; the fixing nail 3 ensures the device is placed securely, preventing displacement due to loach activity or water flow, thus improving the reliability of the catch.

[0042] With the cooperation of the mesh closure mechanism 10, the opening and closing of the loach outlet 5 can be achieved without repeatedly untying and tying the knots on the back side of the outer mesh tube 1, making it more convenient to collect loaches.

[0043] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
