Multifunctional ecological fishing tool

Abstract

The invention discloses a multifunctional ecological fishing tool, comprising a net frame. Main net corners are arranged on two sides of the net frame and connecting rings are respectively arranged attwo ends of the front of the net frame; bump rubber plates are arranged below the connecting rings respectively; a plurality of disturbing chains are uniformly distributed at the back of the net frame, the tail end of each disturbing chain is provided with a disturbing shovel, and the disturbing shovel is a spade-shaped sheet; a plurality of iron chains are connected to the back of the net frame,the tail ends of the iron chains are connected with a bottom cross beam of a bottom net bracket; a bottom net is arranged at the bottom of the bottom net bracket and consists of multiple bottom net rings connected mutually; a net-opening chain is arranged at the front end of the bottom net and is connected with the bottom end of the back of the net frame; cylindrical floaters are arranged in thefront of the bottom net, and center shafts of the floaters are distributed horizontally; a sled is arranged at the bottom of the bottom net bracket; the fishing tool further comprises a net covering,and the net frame and the bottom net bracket are covered with two ends of the net covering respectively.

Description

technical field [0001] The invention relates to a fishing net, in particular to a multifunctional ecological fishing net. Background technique [0002] At present, in my country's coastal areas, the scallop breeding industry is developing rapidly, especially the Ezo scallop, which was mainly produced in Japan, has now become a key breeding industry in Liaodong Peninsula, Shandong Changdao and other sea areas in northern my country, especially suitable for large-scale farming The bottom sowing multiplication method has developed extremely rapidly and has become industrialized. Accompanied by the industrialized model breeding of scallop by bottom sowing, the quality of fishing technology directly affects the yield and quality of scallop. At present, the fishing nets for scallops generally have defects such as high missed catch rate, high damage rate and high scallop sediment content. In order to increase production, repeated fishing has to be carried out, which seriously damag...

AI Technical Summary

Problems solved by technology

However, the traditional fishing nets have the following problems: the net frame includes two main nets and multiple auxiliary nets, resulting in a large overall quality of the net frame, and the phenomenon of shell pressing in the auxiliary nets, and energy consumption during the dragging process High; the grid frame is connected with the bottom net, and the bottom net is stressed during the dragging process, and the net mouth chain is lifted, and there is a phenomenon of shell leakage; the deformation of the bottom net and the mesh bag is serious during the dragging process, which is not conducive to the penetration of sediment by the net; elastic force Tooth dragging has a great impact on the seabed, too much dragging is easy to cause damage to the seabed
