Abstract

The invention relates to a device for catching river snails. The device for catching river snails is characterized by comprising a netting bag (6). An upper edge opening (10) of the netting bag is directly connected with a net stick (1) by a rope, a lower edge opening (9) of the netting bag is provided with net drops (2) and connected with the net stick by 4-8 connecting ropes, the net stick is fastened with a hauling rope (4), and the hauling rope is also fixed with a counterweight (5); two corners of the netting bag are provided with cuffs (7), the ends of the cuffs are fastened firmly by tying ropes (8). The netting bag and the cuffs are made of 9-12 strands of plastic wires; the hauling rope is made of 90-120 strands of plastic wires; and the connecting rope is made of 36-60 strands of plastic wires. The net drops are made of iron, and each net drop is 20-30 gram in weight. The counter-weight-stone is made of 1.5-2.5 kilogram of concrete. The device for catching river snails has the advantages of convenient use, flexible operation, intact and fresh caught river snails, little influence to the underwater environment and great fishing amount.

Description

A kind of device of catching the river spiral shell

Technical field

The present invention relates to a kind of device of catching the river spiral shell, the river spiral shell is a kind of aquatic mollusk, live in pool, the freshwater lake more, and delicious meat, nutritious, be first-class delicious food.

Background technology

People catch the existing very long history of river spiral shell, and the river spiral shell is not only one indispensable on people's dining table delicacies, and important especially traditional Chinese medicine can heat-clearing, Li Shui, make eye bright, and medicinal efficacy is remarkable.At present people catch adopt of river spiral shell more and free-handly fish for or fish for copying son, and such mode of fishing for only is adapted at than the shallow water territory, and the manpower of labor, time, also are not suitable for large-scale river spirodromy product.I develop a kind of novel trap setting according to the experience of fish production for many years in conjunction with up-to-date capturing technology.This device is applicable in the freshwater of the multiple degree of depth, and is fit to large-scale river spirodromy and produces, and can reduce the expending of manual work, and can guarantee the wilderness demand of people to the river spiral shell again.Through retrieval, do not find similar trap tool.

Summary of the invention

The present invention provides a kind of device of fishing for the river spiral shell.

For realizing above-mentioned purpose, the present invention adopts following technical scheme:

A kind of device of fishing for the river spiral shell is characterized in that it is by etting bag (6); The top mouth (10) of etting bag directly is connected with rope with net bar (1), and the following mouth of etting bag (9) is established to net and weighed down (2) and be connected in the net bar with 4-8 root connection cord (3), and the net bar also is to draw in the net to restrict (4), and drawing in the net to restrict also is fixed with counterweight stone (5); Two turnings of etting bag also are provided with cuff (7), and cuff is terminal to be fastened in a down-to-earth manner with tying rope (8).

In the above-mentioned material, etting bag, cuff are made with 9-12 thigh plastic cord; Draw in the net to restrict and make with 90-120 thigh plastic ties; Connection cord is made with 36-60 thigh plastic ties.Net weighs down uses iron work, each heavy 20-30 gram.Counterweight stone is with 1.5-2.5 kilogram concrete for making.

Operation principle of the present invention: the device that will fish for the river spiral shell is placed into waters to be caught.Tie up on motor sailboat or the razshiva drawing in the net rope, start ship ship is advanced with the speed of 1-4 kilometer per hour, wait to fish for the device that will fish for the river spiral shell behind the spiral shell of river and pull out the water surface, decontrol the river spiral shell that tying rope is poured out the inside, handle assembly is put into water and is continued to fish for again.When using this to fish for device, can suitably adjust the quantity that net weighs down, to reach optimum state according to water-bed ambient conditions.Suitably increase and decrease net according to the thick shallow and soft or hard of water-bed mud and weigh down quantity,, otherwise then reduce the quantity that net weighs down if water-bed mud is few or more then need increase net and weigh down quantity.

Advantage of the present invention: easy to use, the flexible operation of this device, the river spiral shell of fishing for is complete fresh and alive, and little to water-bed environmental influence, amount of fishing is big.
