Description

  The present invention relates to an improvement of an animal net used to prevent the invasion of wild animals such as wild boars in order to protect the crops cultivated in the field.

Conventionally, there are various types of nets for preventing bird damage and beast damage.
There are already known metal fences knitted from a synthetic resin base yarn (knitted), knitted from a single fiber made of synthetic resin, or a metal fence formed from a wire mesh.
Furthermore, there are those described in the following patent documents that were specially developed for use in wildlife such as wild boar, but these are all made of a twisted yarn obtained by twisting a thin stainless steel wire to a synthetic resin fiber. A net yarn was produced, and the net was knitted using the net yarn mixed with the metal wire.

In addition to the above-mentioned twisted yarn, the net described in Patent Document 1 has a durability enhanced by reinforcing the insertion portion of the net tension rope.
In the net described in Patent Document 2, the twisted yarn is efficiently formed.
In the net described in Patent Document 3, the production of twisted yarns is more limited as described above.
The net described in Patent Document 4 is of a fence type, and the size of the mesh is made different between the upper part and the lower part.

In the anti-beast net using the above-mentioned conventional mesh wire mixed with metal wire, it takes time and effort to produce the knitting yarn by twisting the metal wire, that is, the stainless steel wire with the synthetic resin fiber, and the production cost is also Come on.
Due to the high cost of the twisted yarn mixed with the metal wire, the size of the mesh (mesh) is inevitably large.
Usually, the degree of mesh is, for example, about 10 cm on a side if the mesh is a rhombus mesh (having a rhombus mesh). This size is sufficient for wild boars, etc., but at the same time, small animals such as mice have no effect at this size.
If the size of the mesh is as small as about 5 cm × 5 cm, the cost will naturally become expensive.

Therefore, the purpose of the present invention is to improve wild boar nets such as wild boars, but the scale of the wild boar is reduced to prevent wild boars and other pests from biting into their nets and biting them. At the same time, the problem is to prevent crop damage from small animals such as mice, and the problem is to provide an animal net that can reduce the production cost even if the scale is reduced. is there.
Of course, improving the strength for wild boars is a basic issue.

In order to solve the above-mentioned problem, a first aspect of the present invention is a network fabric obtained by knitting synthetic resin mesh yarn into a mesh, and knitting a portion of the mesh with a metal wire, and at least a portion of the mesh The animal net is characterized by having a metal net area formed of a metal wire.
Here, the “at least part” means that at least one metal mesh area provided in the mesh is provided, and includes that this metal mesh area can be provided at a plurality of locations. Meaning.

According to a second aspect of the present invention, in the first aspect of the present invention, the mesh is a square mesh, and the vertical and horizontal sizes of the mesh are in the range of about 10 mm to about 40 mm, respectively. Is within a range of about 0.2 mm to about 0.5 mm, and the metal net area is within a range of about 50 cm above the lowermost end when the net is erected and installed. It is a beast net.
Here, as a range where the metal wire network area is provided, it was specified as “a range of about 50 cm from the lowermost end when the net was erected and installed”, but this “when erected and installed” This is because when a net is erected by a pile or the like, it may be installed along the ground so that the bottom of the net is covered with the ground, but in that case, the net rises from the ground. It means a range of about 50 cm from the lowest end.

  According to a third aspect of the present invention, in the first or second aspect, the net is knitted simultaneously using a plurality of synthetic resin single fibers and a plurality of stainless steel wires by Russell knitting. It is a beast-proof net characterized by.

In the first one of the present invention, when a part of the net, for example, a wild boar or the like pest invades, a part corresponding to the height of the pest is knitted from a metal wire alone. By providing the area, there is no risk that the net will be bitten by the pests.
If it is a wild boar, there is no risk of being pushed up by its fangs or being bitten by its teeth, and the net of the net of this net prevents the intrusion, thereby preventing crop damage such as fields. It is.
Moreover, since only a part of the net is a metal wire, the manufacturing cost can be reduced.

In the second device of the present invention, the shape and size of the mesh of the mesh, the type and diameter of the metal wire are limited, and the position of the metal mesh area is also limited.
Thereby, the effect similar to the said device becomes more effective against pests such as wild boars, and damage from small animals such as mice can be prevented.

  In the third device of the present invention, the method of knitting the net is further specified, and by adopting a Russell knitting, a plurality of synthetic resin monofilaments and a plurality of stainless steel wires and other metals Since the net can be knitted simultaneously using the wire, the net can be manufactured extremely efficiently, which contributes to labor saving and a reduction in manufacturing cost.

It is front explanatory drawing of the lower part of the beast net which concerns on one Embodiment of this invention. It is expansion explanatory drawing of the metal netting area part which concerns on the said embodiment.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
