Description

  The present invention relates to an animal net that makes it difficult to break a net by an animal and enhances a tension rope insertion portion to improve durability.

  If the shoots and bark of crops and afforested trees are left open as they are, they will become precious foods such as wild deer, persimmons and moths. Therefore, in order to prevent this, a net is placed around farmland and afforested land. It is a conventional practice to install the cable by hanging it on a support with a tensioning rope and stretching it like a fence.

  Conventionally, the following nets for preventing the invasion of such wild animals existed.

(1) A net composed of chemical fibers such as polyethylene.
(2) Net coated with repellent.
(3) A wire mesh composed of relatively thick wires.

  In the case of (1), since it is lightweight, it has good workability and can take up a large development area even if the number of workers is not so large. On the other hand, it may be bitten by an animal. The long-term effect was not expected.

  In the case of (2), dissolution and outflow of the repellent was caused by the natural environment, and this could not be expected to have a long-term effect.

  In the case of (3), although it is not bitten by animals and breaks the net, it becomes bulky and heavy, has poor workability, and develops along terrain undulations It was difficult to get close to impossible, and rusting over time was inevitable.

Therefore, as shown in Patent Document 1 and Patent Document 2 as an animal net to solve the above problems, an animal net that is configured by mixing a synthetic fiber and a metal wire having a diameter of 0.3 mm or more as a net material. is there. It was confirmed that the introduction of a metal wire of 0.3 mm or more could prevent the animal from breaking the net, and that point was superior to the above.

  However, in the animal nets described in Patent Document 1 and Patent Document 2 described above, it is possible to make the mesh legs thinner by mixing the metal wire into the synthetic fiber. The weight of the animal net is heavier than that of synthetic fiber alone.

  In addition, by putting metal wires that are rigid compared to synthetic fibers, the netting becomes difficult to deform and the elongation decreases, and these forces are reduced by the deformation and elongation of the netting against external forces such as impact and wind pressure. The ability to absorb was weakened.

  So, if you install the rope through the tension net to unfold and stretch the net, and hang it on the support, the impact and wind pressure when the animal collides with the net In the middle, the force is not absorbed by the deformation of the net, but acts directly on the tension rope insertion point for expanding and stretching the net of the mesh leg at the end of the net.

  In other words, various forces act directly on the tension rope insertion points of the net legs without the forces from each direction being weakened. As a result, it was confirmed that the contact point between the net legs and the tension ropes was worn by rubbing with the tension ropes at all times, and it was easy to break at that location.

  In addition, by mixing metal wires, the mesh legs formed of synthetic fibers can function as an animal net even if they are thinner than before. It was getting weaker.

  In particular, when a wire rope is used as a tension rope, the wire rope has a thickness of about 6 mm, for example, so that the length of the mesh leg in contact with the circumference of the wire rope is very short. The weight per unit length is considerably heavy in addition to the fact that the netting itself is heavy, and there is a problem that it is more easily broken.

That is, the following problems were newly confirmed by constructing the animal net with a net with a synthetic fiber mixed with a metal wire.
(A) The netting itself became heavy due to the mixing of metal wires.
(B) The mesh was difficult to deform due to the insertion of the metal wire, and as a result, the ability to absorb external force due to deformation and elongation of the mesh was weakened.
(C) Since the mesh leg formed by the synthetic fiber was thin, it was weak against rubbing.

  The present invention has been made in view of such circumstances, and an object thereof is to prevent a broken net by an animal by mixing a metal wire into a synthetic fiber and to break a net leg at a tension rope insertion portion. It is to provide a beast net excellent in durability and preventing the above.

  In addition, if the thickness of the metal wire is increased too much, breakage due to wear may be prevented, but this has the disadvantages described in the background art (3). Therefore, the present invention is intended for a metal wire thickness of 0.3 mm to 1.0 mm.

In order to achieve the above object, the anti-animal net of the present invention is developed and stretched in an anti-net net composed of a net having a synthetic fiber mixed with a metal wire having a diameter of 0.3 mm to 1.0 mm. The net legs of 1 to 5 steps from the tension rope insertion portion side including the tension rope insertion portion for forming are made only of synthetic fibers that are not mixed with metal wires and are resistant to rubbing .

  According to the present invention, a metal wire having a thickness of 0.3 mm to 1.0 mm is mixed with a synthetic fiber to prevent a broken net by an animal, and the tension rope insertion portion for tensioning the net is compared with other portions. By strengthening against rubbing, there is an effect that it is possible to prevent breakage due to rubbing with the tension rope at the point of contact with the tension rope of the net legs.

  Next, an embodiment of the animal net according to the present invention will be described with reference to FIG. FIG. 1 is a front view showing a state in which a beast net of the present invention is installed. Reference numeral 1 denotes a net having a mesh leg made of a strand in which a metal wire having a segment diameter of 0.3 mm to 1.0 mm is mixed into a synthetic fiber, which constitutes the animal protection net of the present invention. As for the number of the metal wires, it is not necessary to bite even one wire. However, it does not prevent the mixing of a plurality.

  For example, a stainless steel wire can be used as the metal wire, but a steel wire or the like may also be used. Also, the thickness of the metal lines may be the same, or several types of different thicknesses may be used in combination. Furthermore, the thickness of the metal wire can be appropriately selected and used within a range of 0.3 mm to 1.0 mm according to the use location.

  About the said synthetic fiber, what is necessary is just to select desired things, such as polyethylene and polyester. The network 1 may be a knotted network, a knotless network, or a Russell network, and the shape of the mesh is shown as a rhombus in the one shown in FIG. Hexagonal eyes may be used.

The net 1 is suspended by a tension rope 3 stretched between struts 2, and the lower end is fixed by a presser rope 4 so as to function as a beast-proof net.
That is, a tension rope 3 such as a wire rope is inserted into a tension rope insertion portion 5 for unfolding and tensioning the mesh that becomes the upper end when the mesh 1 is suspended, and the tension rope 3 is attached to the strut 2 erected at a desired interval. The netting 1 is expanded and installed so as to be hooked.

  Therefore, in the anti-animal net of the present invention, the tension rope insertion portion 5 for expanding and stretching the net is strengthened against rubbing compared to other portions. For this purpose, the net legs 6 of the tension rope insertion portion 5 are thicker than other portions. In addition, also in the case of squares and hexagons, the tension rope insertion part is strengthened against rubbing compared to other parts.

  The anti-animal net of the present invention is mainly intended to reinforce the tension rope insertion portion 5 for unfolding and stretching the net, but for example, the insertion portion of the holding rope 4 of the anti-animal net and the column 2 Similarly, the fastening portion may be strengthened against rubbing.

(Reference Example 1)
Next, a reference example of the animal net will be described with reference to FIG. FIG. 2 is an enlarged explanatory view of the tension rope insertion part 5 of the animal net.
The mesh leg 6 of the mesh below the tension rope insertion part 5 through which the tension rope 3 is inserted is a mesh leg 6A having a normal thickness, and the mesh leg 6 of the mesh that becomes the tension rope insertion part 5 at the upper level. The lower side is a net leg 6B that is one step thicker than the mesh leg 6A of the lower stage mesh, and the net leg 6 that is in contact with the upper tension rope 3 is another net leg 6C.

  For example, the screen legs 6B are 1.2 times as thick as the screen legs 6A, and the screen legs 6C are 1.2 times thicker than the screen legs 6B. Further, this magnification may be further increased depending on the knitting machine to be used. Alternatively, in the present embodiment, an example in which the thickness of the screen leg 6 is increased in two stages is shown, but the number of stages to be increased can be arbitrarily selected. For example, the thickness may be increased over several stages by 1.5 times sequentially.

  In order to increase the thickness of the net legs 6, the synthetic fibers and metal wires constituting the net legs 6 can be made thicker, the number of synthetic fibers and metal lines can be increased, or both can be used in combination. Can be thickened. It is also possible to increase the thickness by newly adding a material excellent in wear resistance.

(Reference Example 2)
Next, another reference example of the animal net will be described with reference to FIG. FIG. 3 is an enlarged explanatory view of the tension rope insertion part 5 of the animal net.
A mesh leg 6 serving as a tension rope insertion portion 5 for unfolding and stretching the mesh is formed as a double edge net 7 with two mesh legs 6 that are in contact with the tension rope 3 for tension. .

  In the illustrated example, the number of screen legs 6 is two double edged networks 7, but the number of screen legs 6 is not limited to two. In the present invention, the case where the number of the mesh legs 6 is two or more is collectively referred to as a double edge net.

Next, an embodiment of the animal net according to the present invention will be described with reference to FIG. FIG. 4 is an enlarged explanatory view of the tension rope insertion part 5 of the animal net according to the present invention.
The four stages of the mesh leg 6 on the tension rope insertion part 5 side including the tension rope insertion part 5 for unfolding and stretching the mesh are the synthetic fiber net legs A formed only of synthetic fibers without mixing metal wires. ing. And the net leg 6 below it is a metal wire mixed net leg B in which a metal wire is mixed in a synthetic fiber. In addition, the number of steps of the net legs 6 formed only by synthetic fibers without mixing metal wires may be 1 to 5 steps. Although it depends on the height of the animal protection net, if the synthetic fiber net A is made too far down, the original significance of mixing the metal wire is lost.

  In addition, the synthetic fiber network leg A formed without mixing a metal wire uses a raw yarn strong against rubbing. For example, an aramid fiber or an ultra-high strength polyethylene fiber can be used. By using a synthetic fiber that is resistant to rubbing, the wear resistance is improved, and by not incorporating a metal wire, the deformability at that portion is increased, and the total weight is also slightly reduced.

  It is also possible to use such a fiber that is strong against rubbing only at a portion where the metal wire is not mixed. However, the synthetic fiber of the metal wire mixed net leg B of the net 1 is originally resistant to such rubbing. If a strong and strong material is used, the use of the metal wire is stopped at only a few steps of the mesh leg A which is the synthetic fiber net A, and the synthetic fiber net A is replaced with the synthetic fiber of the metal wire mixed net leg B. You may form with the same raw material.

  In this case, by changing the metal wire to a synthetic fiber that is strong against rubbing, the synthetic fiber net leg A is durable against rubbing without changing the thickness of the net leg B and the net leg almost. Can be improved. When synthetic fibers that are resistant to rubbing are used, the thickness of the net legs only needs to be 2 mm to 5 mm in the case of ordinary anti-brain nets. It becomes possible to improve.
