Description

Technical Field

[0001] This utility model relates to the field of anti-escape net technology, and in particular to a liftable anti-escape net for rice-shrimp co-cultivation fields. Background Technology

[0002] In rice paddy crayfish farming, preventing crayfish escape is crucial for ensuring profitability. Currently, traditional methods for preventing crayfish escape often involve a single mesh structure directly erected around the edge of the paddy field. However, this method has several drawbacks: Firstly, the mesh fibers are thin and the mesh openings are mostly square, making it easy for crayfish claws to snag on the fibers and climb up the mesh to escape, resulting in poor escape prevention. Secondly, the height of traditional escape-prevention nets is fixed and cannot be adjusted according to changes in paddy field water levels or crayfish growth stages, limiting their applicability. Furthermore, traditional escape-prevention nets are often installed directly into the soil, with no angle adjustment. When the paddy field has a slope, the net cannot form an effective seal with the ground, easily allowing escaped crayfish to find gaps. These problems lead to a high escape rate during farming, causing significant economic losses for farmers. Therefore, there is an urgent need for a rice paddy crayfish escape prevention device that is effective, height-adjustable, and angle-flexible. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a liftable anti-escape net for rice-shrimp co-cultivation fields, solving the technical problem that the anti-escape net is difficult to form an effective seal with the ground, making it easy for shrimp to escape through loopholes.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A liftable escape-prevention net for rice-shrimp co-cultivation fields includes an escape-prevention component. The component comprises a lower insert plate, an assembly bracket, and several escape-prevention nets. The lower insert plate is located at the bottom of the component and its lower end is tapered. The assembly bracket is U-shaped, and a rotating shaft is rotatably mounted between the top of the lower insert plate and the bottom of the assembly bracket. Two limiting brackets are fixed to the front side of the lower insert plate to limit the forward rotation angle of the assembly bracket. The several escape-prevention nets can be inserted into the assembly bracket, causing the entire escape-prevention component to be in an oblique position.

[0008] Preferably, the lower end of the lower insertion plate has a tapered structure for easy insertion into the paddy field soil; side sliding rails are provided on both inner walls of the assembly bracket, and a bottom sliding rail is provided at the bottom of the assembly bracket; bolts are threaded onto both sides of the assembly bracket; a fixing rod is fixed to the rear side of each row of escape-proof nets, and the two ends of the fixing rod have second threaded grooves that match the bolts; the two ends of the fixing rod can be inserted into the side sliding rails; the escape-proof net is a multi-piece independent structure, and the multiple escape-proof nets are connected by the fixing rods to form a large-area protective structure; extension brackets can be installed on both ends of the assembly bracket, and a threaded rod is fixed to the lower end of each extension bracket; the two ends of each assembly bracket have first threaded grooves that match the threaded rod; the extension bracket is fixedly connected to the assembly bracket by rotating the threaded rod into the first threaded groove.

[0009] Preferably, the rotating shaft frame includes a fixed seat fixed to the top of the lower core plate and a rotating seat fixed to the bottom of the assembly bracket, and the fixed seat and the rotating seat are rotatably connected by a pin.

[0010] (III) Beneficial Effects

[0011] Significantly effective at preventing escape: By setting the entire escape-prevention component at an angle and combining it with multiple independent escape-prevention nets to form a large-area protective structure, the problem of traditional net structures being caught by lobster claws is avoided. Lobster claws cannot move on the escape-prevention net surface, effectively preventing lobsters from climbing and escaping, and greatly reducing the escape rate.

[0012] Adjustable height and highly adaptable: The two ends of the assembly bracket can be extended by the cooperation of the threaded rod and the first threaded groove. The overall height of the escape prevention component can be flexibly adjusted according to changes in paddy field water level, crayfish growth stage or different paddy field height requirements, making it suitable for various sizes of paddy field farming scenarios.

[0013] Flexible angle and easy installation: The lower insert plate and the assembly bracket are connected by a rotating shaft frame. With the help of the limiting fixing frame, the rotation angle of the assembly bracket can be limited, so that the anti-escape component can flexibly adjust the angle of inclination according to the slope of the paddy field to ensure good sealing protection with the ground. At the same time, the tapered structure at the lower end of the lower insert plate makes it easy to quickly insert into the soil. The anti-escape net is fixed to the assembly bracket by the side slide rail and bolts. The installation and disassembly process is simple and efficient.

[0014] Stable structure and good durability: The components are securely assembled through threaded connections, shaft connections and other means. The overall structure has high strength and can withstand the impact of lobsters and the erosion of the field environment. It has a long service life and reduces the equipment replacement cost for farmers. Attached Figure Description

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the overall concept of the technical solution in this application embodiment is as follows:

[0022] To address the problems existing in the prior art, this utility model provides a liftable anti-escape net for rice-shrimp co-cultivation fields, including an anti-escape component 1. The anti-escape component 1 includes a lower insertion plate 11, an assembly bracket 14, and several anti-escape nets 23. The lower insertion plate 11 is located at the bottom of the anti-escape component 1, and the lower end of the lower insertion plate 11 is conical. The assembly bracket 14 is U-shaped, and a rotating shaft frame 13 is rotatably installed between the top of the lower insertion plate 11 and the bottom of the assembly bracket 14. Two limiting fixing frames 12 are fixed to the front side of the lower insertion plate 11, and the two limiting fixing frames 12 are used to limit the angle of forward rotation of the assembly bracket 14. Several anti-escape nets 23 can be inserted into the assembly bracket 14, so that the anti-escape component 1 is in an oblique state.

[0023] The lower end of the lower insertion plate 11 has a conical structure, which facilitates insertion into the paddy field soil. The inner walls of both sides of the assembly bracket 14 are provided with side slide rails 15, and the bottom of the assembly bracket 14 is provided with a bottom slide rail 16. Bolts 2 are threaded on both sides of the assembly bracket 14. Each row of escape-proof nets 23 is fixed with a fixing rod 22 at the rear. The two ends of the fixing rod 22 are provided with second threaded grooves 24 that are compatible with the bolts 2. The two ends of the fixing rod 22 can be inserted into the side slide rails 15. The escape-proof nets 23 are multiple independent structures. Multiple escape-proof nets 23 are connected by the fixing rods 22 to form a large-area protective structure. Extension brackets 18 can be installed on both ends of the assembly bracket 14. Each extension bracket 18 is fixed with a threaded rod 19 at the lower end. Each assembly bracket 14 is provided with a first threaded groove 17 that is compatible with the threaded rod 19 at both ends. The extension bracket 18 is fixedly connected to the assembly bracket 14 by rotating the threaded rod 19 into the first threaded groove 17.

[0024] The rotating shaft bracket 13 includes a fixed seat fixed to the top of the lower core plate 11 and a rotating seat fixed to the bottom of the assembly bracket 14. The fixed seat and the rotating seat are rotatably connected by a pin.

[0025] Working principle:

[0026] The first step involves using the escape-prevention component 1 in the paddy field. The escape-prevention component 1 includes a lower insertion plate 11, an assembly bracket 14, and several escape-prevention nets 23. The lower insertion plate 11 is located at the bottom of the escape-prevention component 1, and the lower end of the lower insertion plate 11 is conical. The lower insertion plate 11 is inserted into the soil of the paddy field. The assembly bracket 14 is U-shaped, and a rotating shaft bracket 13 is rotatably installed between the top of the lower insertion plate 11 and the bottom of the assembly bracket 14. Two limiting brackets 12 are fixed on the front side of the lower insertion plate 11. The two limiting brackets 12 are used to limit the angle of forward rotation of the assembly bracket 14. After the lower insertion plate 11 and the assembly bracket 14 are placed, each row of escape-prevention nets 23 can be inserted into the assembly bracket 14. At this time, the escape-prevention component 1 is in an inclined state, which can prevent the crayfish from escaping.

[0027] The second step involves installing side slide rails 15 on both inner walls of the assembly bracket 14, and a bottom slide rail 16 at the bottom of the assembly bracket 14. Bolts 2 are threaded onto both sides of the assembly bracket 14, and a fixing rod 22 is fixed to the rear of each row of escape-proof nets 23. The fixing rods 22 have second threaded grooves 24 at both ends. Both ends of each row of fixing rods 22 can be inserted into the side slide rails 15 of the assembly bracket 14, and the bolts 2 can be rotated into the second threaded grooves 24 to fix the rods 22 and the escape-proof nets 23. Multiple sets of oblique escape prevention measures are employed. Net 23 protects lobsters from being caught by their claws, unlike traditional nets. The escape-proof net 23 is composed of multiple large pieces, preventing lobsters from getting caught and moving on it. Extension brackets 18 can be installed on both ends of the assembly bracket 14. Each extension bracket 18 has a threaded rod 19 fixed at its lower end, and each assembly bracket 14 has a first threaded groove 17 at both ends. The extension bracket 18 can rotate the threaded rod 19 into the first threaded groove 17 for fixation, thus making it suitable for paddy fields of different heights.

[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
