Description

A kind of device that catches the river spiral shell

Technical field

The utility model relates to a kind of device that catches the river spiral shell, and 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 traditional Chinese medicine especially 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 fishing style is only suitable for than the shallow water territory, and expends a large amount of manpowers, time, also is not suitable for large-scale river spirodromy product.I develop a kind of novel trap setting according to the experience of for many years fish production 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 product, can reduce artificial expending, and can guarantee that again people are to the wilderness demand of river spiral shell.Through retrieval, do not find similar trap tool.

The utility model content

The utility model provides a kind of device of fishing for the river spiral shell.

For achieving the above object, the utility model 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 is connected 1 with the net bar) directly connect with rope, etting bag following mouthful (9) is established net pendant (2) and is connected in the net bar with 4-8 root connection cord (3), 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 of 9-12 thigh plastic cord; Draw in the net to restrict and make of 90-120 thigh plastic ties; Connection cord is made of 36-60 thigh plastic ties.The iron work of net pendant, each heavy 20-30 gram.Counterweight stone 1.5-2.5 kilogram concrete for making.

Operation principle of the present utility model: 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, will fish for the device of river spiral shell and pull out the water surface after fishing for the river spiral shell, 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 according to water-bed ambient conditions the quantity of net pendant, to reach optimum state.Suitably increase and decrease net pendant quantity according to the thick shallow and soft or hard of underwater mud, if underwater mud is few or more then need to increase net pendant quantity, otherwise then reduce the quantity of net pendant.

Advantage of the present utility model: 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 large.
