Problems solved by technology

This type of structure can make the seine net settle quickly and prevent fish from escaping, but its structure is complicated. During the production, it is necessary to manually string up the lead blocks and tie them to the lower net. The lead can be controlled according to the weight of different parts. block density
The traditional sinker gang is suitable for the purse seine operation mainly by manual operation on the deck, but due to the lead hammer, it is not suitable for the purse seine operation operated by the net winding machine, and the net can only be lifted and released manually, and the operation time of lifting and unwinding long, seriously affecting fishing efficiency
[0003] Because the traditional sinkers are lead particles connected by wires, and the flexibility of the wires is very good, the traditional sinkers may hang, and it is easy to scratch the netting and seabed debris, causing the netting or sinking. The sub-gang is damaged, resulting in a short service life of the sub-gang, and at the same time, there will be fish leaks in the net, which greatly reduces the fishing harvest

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see Figure 2 to Figure 4 , a kind of encapsulation net Shenzigang, comprising several wires 1, on which some lead grains 2 are arranged in series, and the outer side of several said wires 1 is coated with a wrapping layer 3, and the length of said Shenzigang is L =(2.2~2.7)×10L1, where L is the length of the sinker, L1 is the length of the waterline of the ship, and at least one lead particle is correspondingly arranged in the wrapping layer. In this embodiment, the line 1 is poly Ester thread, polyester thread is used to improve the strength of the thread connected by the lead shot 2 and prevent it from breaking. Because the polyester and polypropylene blended layer is wear-resistant, the polyester and polypropylene blended layer are selected as the wrapping layer. L=(2.2~2.7)×10L1 is mainly an empirical formula obtained through practical d...

Abstract

The invention discloses a ground rope with a bag enclosure net. The ground rope comprises a plurality of wires, wherein each wire is serially provided with a plurality of lead particles, the outer side of each line is coated with a coating layer, the length of the ground rope is equal to (2.2-2.7)*10L1, L is the length of the ground rope, and L1 is the length of a water line of a ship. The ground rope has the advantages that the manufacturing is convenient, the suspension is avoided, the service life is long, and the ground rope is suitable for operation using net coiling machines.

Description

technical field [0001] The invention relates to the technical field of multifunctional winches, in particular to a marine multifunctional winch, in particular to a purse seine sinker. Background technique [0002] The purse seine sinker used in the existing fishery is composed of polyethylene rope, cylindrical lead sinker (open hole in the middle) or flat pottery sinker or hammer-shaped stone sinker, etc. ( figure 1 ). The upper edge of the Shenzi Gang is ligated to the lower class, and the size and weight of the Shenzigang are different, and the distribution gradually increases from the net mouth to the wing end. Shen Zigang is symmetrically assembled left and right, and the lower middle gang is connected with the left and right lower gang with shackles. This type of structure can make the seine net settle quickly and prevent fish from escaping, but its structure is complicated. During the production, it is necessary to manually string up the lead blocks and tie them to t...
