Abstract

PROBLEM TO BE SOLVED: To provide a net for preventing animal injury, capable of efficiently forming a metal wire built-in net having a fixed strength. SOLUTION: In a net yarn 3 formed by twisting a pair of yarns 1 and 2, a synthetic resin yarn is used as one yarn 1 of a pair of the yarns 1 and 2 and a metal wire as the other 2 of a pair of the yarns 1 and 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net for preventing damage to wildlife, such as crops and trees, and an accident prevention net, which is stretched around farmland, afforestation, roads, railways, and houses. .

[0002]

2. Description of the Related Art For example, in a farmland or a fruit orchard adjacent to a natural mountainous area, wild animals frequently appear and disappear in recent years, and these crops may be eaten away and the harvest thereof may be greatly damaged.

[0003] For this reason, pillars are set up at intervals around the above-mentioned farmland or fruit orchard, and a net made of synthetic resin is stretched between these pillars at a height at which wild animals do not jump. However, damage from the wild animals was prevented.

[0004] However, these wild animals gradually cut through the net, make holes in the net, and move back and forth through the hole to damage crops, and the prevention effect was very short-term. .

[0005] In some cases, nets are provided on the market in which a metal wire is inserted into the net yarn so as to prevent the net from being bitten by wild animals. When twisting the yarn, since the elongation ratio between the synthetic resin yarn and the metal wire is different, troubles such as yarn breakage and mechanical failure frequently occur, and the productivity and production efficiency of the net were remarkably reduced. .

Furthermore, due to the difference in the elongation rate between the synthetic resin yarn and the metal wire, the synthetic resin yarn sags and becomes ball-shaped when twisted, and the appearance of the appearance is deteriorated. And other various problems.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a net yarn formed by twisting a pair of yarns is combined with one of the pair of yarns. The object of the present invention is to provide a beast harm prevention net capable of efficiently forming a metal wire-containing net having a predetermined strength by using a resin wire as a metal wire for the other of the pair of yarns. I have.

[0008]

Means of the present invention for achieving the above-mentioned object is to provide a beast harm prevention net consisting of a mesh yarn twisted and formed from a pair of yarns. In one embodiment, a net for preventing animal damage is provided using a synthetic resin thread as one of the threads and a metal wire as the other of the pair of threads.

In addition, one or a plurality of metal wires are twisted.

[0010]

Next, an embodiment of a net for preventing animal damage according to the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral A denotes a beast damage prevention net, which is stretched around or around farmland, afforestation, roads, railways, and houses to damage crops or trees caused by wild beasts from the outside. Alternatively, a net yarn 3 formed by a pair of yarns 1 and 2 for preventing an accident or the like caused by a wild beast or the like.
It is basically composed of

The one yarn 1 of the pair of yarns described above is formed by combining a large number (for example, 20 to 120) of original yarns made of synthetic resin fibers such as nylon, polyester, vinylon, polypropylene, and polyethylene. It is wound around the first bobbin 4 to a predetermined diameter in a preliminary twisting step (not shown).

The other yarn 2 of the pair of yarns is made of one or a plurality of metal wires, and is wound around the second bobbin 5 with a predetermined diameter. When these metal wires are used, a twisted combination of these metal wires 6 is wound around the second bobbin 5 in advance.

As the metal wire 6, an appropriate wire such as an iron wire or an aluminum wire having a predetermined thickness is used. Preferably, if a conductive stainless steel wire is used, corrosion resistance and strength are excellent.

In the knitting step, the thus obtained one yarn 1 and the other yarn 2 are connected to a net A for preventing animal damage having a net yarn 3 and a mesh 8 in a knitting machine 7 as shown in FIG. Are continuously knitted in a knotless mesh.

The one yarn 1 and the other yarn 2 are formed into an integral net yarn 3 while being twisted. As shown in the cross-sectional view of FIG. 2, the other yarn 2 made of a metal wire is a one yarn. 1 and the same twist is given by the pair.

When the net A for preventing beast damage is stretched on the outer periphery of an orchard, for example, when it is stretched around an orchard where it is damaged by beast damage, for example, wild animals such as deer and monkeys, a pillar (not shown) or the like is used. The net A is erected at a predetermined interval, and the net A is stopped by a conventional fastening means (not shown).

Thus, the net A prevents the wild beast from entering the orchard, thereby preventing damage to grown fruits, leaves and trees.

Further, even when trying to cut through the net A on which the wild beast is stretched, the other thread 2 composed of the metal wire 6 constituting the net 3 protects the net 3 from the cutting of the wild beast.

[0020]

According to the present invention having the above-mentioned configuration, there is provided a beast damage prevention net comprising a net yarn formed by twisting a pair of yarns, wherein one of the pair of yarns is a synthetic resin yarn. By using a metal wire for the other of the pair of yarns, in the knitting net process, the net yarn and the metal wire can be knitted smoothly, the trouble is reduced, the productivity of the net and the production efficiency are reduced. Significant improvement and low-cost production are possible.

In particular, since the net yarn and the metal wire are not combined, no sagging or the like due to the difference in the expansion and contraction ratio is caused, the appearance appearance is improved, and the commercial value rises. And so on.
