Shrimp trapping device

Abstract

The invention provides a shrimp trapping device, which relates to the technical field of fishing. The shrimp trapping device comprises a collecting net cage, a central column, an elastic sealing bandand a bait box, wherein a cover body with a plurality of shrimp trapping holes is arranged on the collecting net cage, and a central hole with internal threads is formed in the central part of the cover body; the central column penetrates through the central hole, and external threads are arranged on the central column; one end of the elastic sealing band is fixedly connected to the central columnand the other end is fixedly connected to the cover body, so as to enable the elastic sealing band to cover the shrimp trapping holes, and through holes are formed in the elastic sealing band; and the bait box is fixedly connected to one end of the central column. Shrimps cannot escape from the shrimp trapping holes, the action is quick, when the shrimps are collected and taken out of the device,the shrimps in the collecting net cage can be effectively prevented from escaping quickly due to shock, so that the amount of shrimps collected is increased; and meanwhile, the device is small and convenient, easy to operate, suitable for personal use, and does not cause damage to surrounding crops.

Description

technical field [0001] The invention relates to the technical field of fishing, in particular to a device for trapping shrimp. Background technique [0002] Shrimp is rich in protein and low in fat. It is a food that is more commonly eaten in people's daily diet. Shrimp are crustaceans related to crabs and lobsters. It has a flat, elastic translucent body in the middle, and a fan-like tail. Shrimp swimming is very different from fish. Fish can swim forward by swinging their tail fins. Shrimp does not have tail fin like fish, but only has one tail and many small legs. So how does it swim? Shrimp also has its "brilliant tricks". When it swims, those swimming feet stroke backwards frequently and neatly like wooden oars, and the body slowly drives forward. When frightened, its abdomen flexes and stretches nimbly, and its tail paddles forward and downward, and can leap backward continuously at a very fast speed. When the net was collected during fishing, some shrimp brothers...

AI Technical Summary

Problems solved by technology

[0003] The way of catching shrimps in the prior art is to trap shrimps and crabs in foldable ground cages. Its structure is as follows: more than two main frames are supported in the mesh cover to form a net cage, and the upper end of the main frame is fixed with a hook extending straight to the outside of the cage. The support pole is connected with a shielding net on the straight section outside the net cage, and there are more than two lure openings on the net cover on the side of the net cage under the shield net. Its trapping principle is that in the net cage Put the bait, when the shrimp and crab smell the bait in the net cage, they will search for it and hit the net cover. Since there is a shielding net above the lure opening of the net cover, the shrimp and crab will enter the net cage along the lure opening in and can no longer exit

But this structure is troublesome to set up the net, and it will overwhelm the crops in the pond. At the same time, the large size of the fishing cage is not suitable for personal outdoor shrimp fishing, and it is not easy to carry.

Moreover, the bait is put in at one time, and it cannot be added in time during the fishing process.
