Technical Field

The invention relates to the technical field of fishing, in particular to a device for trapping shrimps.

Background

The shrimp is rich in protein and low in fat content, and is a food which is usually eaten by people in daily diet. Shrimp is a crustacean, related to crabs and lobsters. In the middle there is a flat, flexible, translucent body with a fan-like tail. Shrimp swimming is different from fish, fish can swim forwards by swinging tail fins, and shrimp does not have tail fins like fish, only has a tail and a plurality of lower legs, and is what swimming. Shrimp also has its "high hell". When the swimming pool swims, the swimming feet can frequently and regularly slide backwards like a wood paddle, and the body is driven forwards slowly. When frightened, the abdomen is agilely bent and stretched, the tail part is downwards and forwards to strike water, and the abdomen can continuously jump backwards at a very quick speed. When the net is collected during fishing, part of the shrimps which react quickly can escape from the fishing device.

Disclosure of Invention

In view of the above, the present invention provides a device for trapping shrimps, comprising a collecting net cage having a cover body with a plurality of shrimp catching holes, the cover body having a central hole with internal threads; a central post passing through the central bore, the central post having external threads; one end of the elastic sealing belt is fixedly connected to the central column, the other end of the elastic sealing belt is fixedly connected to the cover body, so that the elastic sealing belt can cover the shrimp catching hole, and the elastic sealing belt is provided with a through hole; the bait box is fixedly connected to one end of the central column.

Preferably, the central column has a central cavity, and the central cavity is communicated with the bait box.

Preferably, the collecting net cage is a steel wire woven net made of stainless steel.

Preferably, the bottom of the collecting net cage is fixedly connected with a fixed claw.

Preferably, the shrimp catching holes and the through holes have the same shape.

Preferably, the shrimp catching holes are one or more of triangular, round and rectangular.

Preferably, the plurality of shrimp catching holes form a shrimp catching hole group, and the shrimp catching hole group is arranged in a radial mode. Preferably, the elastic sealing band is a rectangular elastic band capable of covering the groups of shrimp catching holes.

Preferably, the fixing means is bonding.

The shrimp catching device has the beneficial effects that surrounding shrimps are attracted by the bait to enter the collecting net cage through the shrimp catching holes, the central column is rotated during fishing to enable the elastic sealing belt to be wound and tensioned, the effective working area of the shrimp catching holes is reduced, the shrimps cannot escape from the shrimp catching holes, the action is rapid, the shrimps in the collecting net cage can be effectively prevented from escaping rapidly due to frightening, the shrimp collecting amount is increased, and meanwhile, the shrimp catching device is small, exquisite, convenient, easy to operate, suitable for personal use and free of damage to surrounding crops.
