Cage for catching freshwater shrimps on water surface of large ditch

Abstract

A cage for catching freshwater shrimps on the water surface of a large ditch comprises a cage framework, wherein the cage framework is formed by welding steel bar stand columns; the outer side surface of the cage framework is wrapped with a mesh wall to form a cage body; the cage body is square; four shrimp inlets are formed in mesh walls at the front end and on two side surfaces of the cage body; steel bar inverted whiskers are mounted on the four shrimp inlets and fixed by the mesh walls; an interlayer wall is arranged in an inner cavity in the rear part of the cage body; a shrimp storage cabin inlet is formed in the interlayer wall; shrimp inlet steel bar inverted whiskers are mounted on the shrimp storage cabin inlet; a shrimp storage cabin is connected to the rear part of the interlayer wall; a rope hanging nose and a shrimp getting door are arranged on two sides of the top of the shrimp storage cabin respectively; one end of the shrimp getting door is fixed by a movable hinge, and the other end of the shrimp getting door is connected with a door hook; the shrimp getting door can be opened or closed upwards and downwards under the action of the door hook; and a shrimp trapping bag is arranged in a front inner cavity of the cage body and fixed by shrimp trapping bag pull ropes.

Description

technical field [0001] The invention relates to a cage for catching shrimp, in particular to a cage for catching freshwater shrimp on the water surface of a large ditch, and belongs to the technical field of cages for catching shrimp. Background technique [0002] At present, a kind of shrimp catching tool that people adopt when catching green prawns on the water surface of Dagou is a circular net. There is a circular net opening on the top of the circular net. There is a concave net pocket under the circular net opening. Net rope, the upper end of the net rope is connected with a float. When in use, put bait in the net bag, sink the net into the water, and the float floats on the water surface. When the freshwater shrimp enters the net bag to eat, the circular net can be lifted from the water Freshwater prawns are caught, and the circular nets are all open-type operations. Especially when the net is lifted, the frightened shrimp can escape at any time, that is, all the fres...

Problems solved by technology

[0005] Beneficial effects of the present invention: due to the adoption of the above scheme, after the green shrimp cage is put into the water, the bait in the cage will emit fragrance. The outlet is the small mouth formed by the acupuncture arrangement on the steel bar, facing directly to the shrimp, the green shrimp can no longer go out from the shrimp cage, and the purpose of the present invention has been achieved. The shrimp cage is simple in structure, easy to operate, The effect of catching green prawns is good, and the amount of catching green prawns is large, which can effectively overcome the defects of high escape rate and poor catching effect of green prawns in the existing net bag when catching green prawns
