Abstract

The utility model discloses a cage for catching crabs, which comprises a cage body (9), a fishing net (1) and a fishy smell luring box. The fishy smell luring box is arranged inside the cage body (9). The cage for catching the crabs is characterized in that the cage body (2) is formed by frames of two layers, namely frames of an outer layer and frames of an inner layer. The frames (2) of the outer layer and the frames (4) of the inner layer are connected integrally through connecting rods (3), the fishing net (1) is arranged on the frames (4) of the inner layer, and crab inlets (5) are arranged on the lateral walls of the frames (4) of the inner layer. The crabs are creeping creatures, and the crab inlets are designed to be inclined upwards from a lower position to a higher position, thereby leading the crabs to enter the cage to seek food along a sloped net piece and accordingly obtaining a purpose of catching the crabs. The tail ends of the inlets inside the cage are suspended to form an altitude difference with the bottom of the cage, thereby leading the crabs to not be capable of creeping outside because no stairs exist, obtaining a purpose of preventing the crabs from escaping to the outside, and enabling catching production to be increased. The cage body adopts a steel frame structure, thereby not only being firm and durable, but also greatly prolonging service life of a fishing tool.

Description

A kind of crab cage of catching

Technical field

The utility model relates to a kind of marine fishing fishing gear, specifically is a kind of crab cage of catching.

Background technology

Traditional trap for catching crabs, receive cage equipment owing to lack the throwing of heavy specialty at present, so the cage system is subjected to the technical limitations can only the tiny trap for catching crabs of productive estabilishment, it is also thin partially thereupon that cage mouth specification is influenced by the cage body, the cage mouth is thin to cause the big crab of the scale of construction to be difficult to enter, more have influence on entering synchronously of a plurality of crabs, so the output of fishing for is not high; In addition, the trap for catching crabs scale of construction is thin, in light weight, is subject to the ocean current influence in the seabed and produces drift, and therefore lightweight crab pot can only be adapted at the shallow sea operation, cannot expand to the deep-sea and fish for.Because Fishing Gear and Fishing Method falls behind, make fishing boat all concentrate at the shallow sea and carry out high density and fish for, caused China's inshore fishing resource exhausted phenomenon to occur; The cage body adopts the structure of individual layer, and is not too firm, and in the process of fishing for, fishnet is wearing and tearing easily also, and service life is short.

Summary of the invention

The purpose of this utility model provide a kind of be adapted at various sea areas fishing operation catch the crab cage.

For achieving the above object, the technical scheme that the utility model adopted is:

A kind of crab cage of catching includes cage body, fishnet and raw meat and lures case, and raw meat lures case to be located in the cage body, and described cage body is to be made of inside and outside two layers of framework, and outer framework connects into an integral body by connecting rod and internal layer framework, and described fishnet is located on the internal layer framework; The sidewall of described internal layer framework is provided with the crab inlet.

Described crab inlet is to be made of collar extension frame and internal orifice frame, and the collar extension frame is located on the sidewall of internal layer framework, and the internal orifice frame is positioned at internal layer framework and frame mouth towards oblique upper.

One end of described internal layer framework is provided with the cage door.

The utility model beneficial effect: research and develop simultaneously because newly-designed crab pot is thrown receipts machinery with the crab pot that matches, make the crab pot design break through traditional mode, be provided with broad crab pot inlet, make crab or a plurality of crab of all size that the condition that provides is provided simultaneously, the cage mouth outside is provided with, makes crab to creep easily to enter in the cage from low to high and looks for food, inlet in the cage do not hold unsettled with form the discrepancy in elevation at the bottom of the cage, crab is lost rely on the ladder of creeping to flee, thereby reach the anti-purpose of fleeing and improving fishery output; Because to constitute weight by steelframe big for newly-designed crab pot, be not subject to action of ocean current in the seabed and drift about, thereby reach the requirement that is fit to deep ocean work.Adopt the structure of double-layer frame, not only sturdy and durable, and fishnet played the effect of protection, the service life of having improved fishing gear greatly.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is the utility model structural representation.

Among the figure: 1, fishnet; 2, outer framework; 3, connecting rod; 4, internal layer framework; 5, crab inlet; 6, collar extension frame; 7, internal orifice frame; 8, cage door; 9, cage body.

Embodiment

As shown in Figure 1, a kind of crab cage of catching includes cage body 9, fishnet 1 and raw meat and lures case, raw meat lures case to be located in the cage body 9, described cage body 9 is to be made of inside and outside two layers of framework, and outer framework 2 connects into an integral body by connecting rod 3 and internal layer framework 4, and described fishnet 1 is located on the internal layer framework 4; The sidewall of described internal layer framework 4 is provided with crab inlet 5.

Described crab inlet 5 is to be made of collar extension frame 6 and internal orifice frame 7, and collar extension frame 6 is located on the sidewall of internal layer framework 4, and internal orifice frame 7 is positioned at internal layer framework 4 and frame mouth towards oblique upper.

One end of described internal layer framework is provided with cage door 8.

Operation principle: crab lures at raw meat under the attraction of case, enters in the cage from three-dimensional crab pot inlet, and owing to setting that the crab pot inlet is inclined upwardly from low to high, entering looks for food in the cage obtains trapping thereby crab is creeped along slope net sheet.Inlet in the cage do not hold unsettled with form the discrepancy in elevation at the bottom of the cage, crab is lost rely on the ladder creep to flee, thereby reach anti-flight and improve the purpose of fishery output, be provided with the crab pot door to the internal layer framework at another of cage body, as long as open the cage door, just can easily crab be taken out.

The above is a preferred implementation of the present utility model, certainly can not limit the interest field of the utility model with this, should be understood that, for those skilled in the art, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
