Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pest-preventing device, and more particularly to a pest-preventing device suitable for protecting agricultural products and the like from boars.

[0002]

2. Description of the Related Art In recent years, the devastation of the natural environment has progressed, and the feed of various animals in the mountains has decreased. Therefore, the above animals have invaded human living areas, and in particular, have been damaged by feeding damage to agricultural products. It occurs frequently and threatens the lives of producers of agricultural products.

Conventionally, as a method of protecting crops and the like from animals, it has been generally practiced to surround fields and forests where crops and the like are cultivated with protective fences using galvanized sheets, resin corrugated sheets or the like.

By the way, it is necessary to set conditions such as height and strength of the protective fence in accordance with the kind of animal whose invasion is cancer-proof. Basically, a higher and stronger structure is adopted. Is preferred.

[0005]

However, in setting the height and strength of the protective fence in actual installation, there is a limit naturally in terms of cost, etc. If the protective fence is set high, the problem of wind pressure must be taken into consideration. I won't.

[0006] For example, in the case of a boar that is greatly damaged by food damage, it has been confirmed that the jump height at a fixed position is 1500 mm or more. Therefore, in order to prevent the invasion of the boar, the height of the protective fence should be high. Must be set higher than that, but setting the height higher makes it weaker in strength and higher in cost.

Therefore, an object of the present invention is to make it difficult for an animal to jump near a protective net, and to prevent the jumping over, thereby making it possible to set the height of the protective net as low as possible. To provide an intrusion prevention device.

[0008]

In order to solve the above-mentioned problems, the present invention is directed to a protective net made of wire mesh, which is arranged upright, and a tip is lowered to a lower position outside a protective zone for this protective net. And a skirt member arranged in a slanting shape, and the skirt member is movably attached to a protective net.

The protective net is formed, for example, by crossing a vertical line and a horizontal line using an iron wire having a diameter of 3.2 mm and welding the intersections. For example, the width is 1500 mm and the height is a boar jumping. It is set to 1800 mm, which is difficult to overcome. The size of the mesh of the protective net is set to be a small mesh by arranging the horizontal lines densely so that the lower half part can prevent the invasion of small animals such as rabbits and raccoon dogs.

Further, the skirt member is formed of a wire mesh made of iron wire or band iron or expanded metal to have a structure having a mesh or an opening into which a boar's foot fits, and its rear end is located at a predetermined height position of the protective mesh. It is attached so that it can be raised and lowered by pivoting it on a horizontal line, and when this skirt member is tilted down with the protective net standing upright, the tip touches the ground and becomes a downwardly sloping slope. Since he dislikes riding on an inclined skirt member having meshes and openings in which the mesh fits, jumping at the base portion of the protective net does not happen to get over the protective net.

If the skirt member is flipped up to stand up and this standing state is temporarily fixed to the protective net, the work for cutting the weeds generated on the ground below the skirt member can be carried out without any trouble, and the weeds can be covered with the weeds. Therefore, the function of the skirt member can be maintained.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

The pest-preventing device for pests according to the first embodiment shown in FIGS. 1 to 3 is a wire netting protective net 1 arranged upright, and a lower part outside the protective zone for the net 1. 2. A skirt member 2 that is arranged in a slanted shape with its tip falling downwards
The skirt member 2 is attached to the protective net 1 so as to be able to move up and down.

In the case shown in the figure, the protective net 1 is formed by using an iron wire and intersecting a vertical line 3 and a horizontal line 4 and welding the intersections, and the diameter of the iron wire to be used and the width and height of the protective net 1 are used. The size of the mesh may be set according to the type of animal to be protected. For example, in the case of boar, a preferable example is to use iron wires with a diameter of 3.2 mm for the vertical lines 3 and the horizontal lines 4, and protect them. The width of the net 1 is set to 1500 mm, and the height is set to 1800 mm, which makes it difficult for the boar to jump over.

In the mesh of the protective net 1, the upper half parts of the vertical lines 3 and the horizontal lines 4 are arranged at an interval of 100 mm or 150 mm, respectively, and the lower half parts of the horizontal line 4 are arranged at an interval of 50 mm or 75 mm. By welding the intersections and making the lower half of the mesh smaller, the strength of the lower part is improved and the invasion of small animals such as rabbits and raccoons can be prevented.

The protective net 1 may be formed in a net shape using not only the iron wire as shown in the drawing, but also a band iron. In any case, since it is a net, it is a structure that receives little wind pressure. It has become.

The skirt member 2 is formed of a wire mesh or expansed metal welded with an iron wire or a band iron as shown in the figure, and is formed into a structure having a mesh or an opening into which a boar's foot fits, for example, to protect it. The net 1 has a width substantially equal to that of the net 1 and a length in the front-rear direction capable of forming a sufficiently inclined surface on the outside of the net 1. The rear end is pivotally fixed to the horizontal line 4 at a predetermined height position of the net 1. When the skirt member 2 is tilted with the protective net 1 arranged upright as shown in FIGS. 1 (B) and 3, the tip is grounded and the tip is lowered. Become a state.

Further, the skirt member 2 is kept upright by flipping up and standing upright and detachably temporarily fixed to the horizontal wire 4 of the protective net 1 using an appropriate temporary fitting 5 made of a wire. You can do it.

The pest-preventing device for pests according to the second embodiment shown in FIG. 4 is the same as the pest-preventing device for pests according to the first embodiment. Is fixed to the vertical wire 3 via the insulating member 6, and a current is passed through the horizontal wire 4 with the protective net 1 standing upright,
An animal that climbs up the protective net 1 such as a monkey is prevented from getting over the protective net 1 and entering.

Further, FIG. 5 shows another example of the second embodiment, in which only the upper ends of the vertical lines 3 located on both sides of the protective net 1 are projected upward, and the upper ends of the vertical lines 3 which are projected are shown. A plurality of horizontal wires 4 for passing a current between the parts are electrically stretched via an insulating member 6.

In each of the embodiments, the protective net 1 is used in the state where the horizontal line 4 is located on the side of the protective zone with respect to the vertical line 3, but the reverse arrangement is adopted. Alternatively, the protective net 1 and the skirt member 2 may be added with a rust preventive function by plating, or may be colored in accordance with the landscape of the installation portion.

The device for preventing invasion of pests of the present invention is constructed as described above, and in order to protect agricultural crops and the like from animals, thinning materials and the like are provided at intervals corresponding to the width of the protective net 1 as shown in FIG. The piles 7 using the
Are arranged upright, and both ends of the protective net 1 are fixed to the pile 7 with nails or the like while the lower end of the vertical wire 3 of the protective net 1 is inserted into the ground.

In this way, the protective netting 1 is used to surround the fields and forests where agricultural products are cultivated, and to block the approach path, and at the bottom of each protective netting 1 is attached to the outside of the protective zone. The skirt member 2 is laid down so that the tip of the skirt member 2 is in contact with the ground and the tip of the skirt is inclined downward.

In such a state, animals approaching the protective net 1 in an attempt to enter the inside of the protective zone, for example, wild boars, dislike approaching the protective net 1 because the skirt member 2 is present at the bottom thereof. When trying to get on the skirt member 1, it is difficult to get on because it is inclined, and since it is essentially disliked to get on the inclined skirt member 2 having a mesh or an opening into which the foot fits, the boar is It is not possible to jump at the root part of the protective net 1, so that the protective net 1 can prevent direct intrusion and the skirt member 2 can prevent the protective net 1 from jumping over due to jumping, and therefore the protective zone. The boar can be prevented from entering the inside of the.

As described above, since the boar is prevented from jumping at the approaching position of the protective net 1, the height at which the boar can jump can be set low, and the height of the protective net 1 is reduced accordingly. It is possible to reduce the materials used.

Further, since the protective net 1 has a finer mesh in the lower half, it can prevent invasion of small animals such as rabbits and raccoon dogs, and furthermore, the protective net shown in the second embodiment. As in No. 1, if an electric current is passed through the upper horizontal line 4, it is possible to prevent the invasion of animals capable of climbing the protective net 1 like a monkey.

When the situation where weeds grow and cover the skirt member 2 in the portion where the protective net 1 and the skirt member 2 are installed as described above, and the function of the skirt member 2 is deteriorated. Requires regular weed cutting.

Therefore, in order to mow the weeds growing under the skirt member 2, as shown in FIG. 2, the skirt member 2 is caused to stand upright by turning the skirt member 2 upward, and the skirt member 2 is set on the horizontal line 4 of the protective net 1. If the skirt member 2 is stopped by the temporary fixing metal 5 and the standing state is maintained, the skirt member 2 does not interfere with the weeding work, and the cutting work can be performed smoothly.

[0029]

As described above, according to the present invention, since the skirt member arranged in an inclined shape with the tip thereof lowered is provided at the lower position outside the protective mesh made of the wire mesh, which is arranged upright, the protection is provided. Animals approaching the protective net trying to enter the inside of the circle do not like approaching the protective net because the skirt member is present at the bottom, so even if they try to ride on the skirt member, they will tilt because they are inclined. Difficult, and therefore
The animal will not be able to jump at the root of the protective net, so that the protective net will prevent direct intrusion and the skirt member will prevent jumping over the protective net, and thus the inside of the protective zone. It is possible to prevent pests from invading into.

Further, since the skirt member is movably attached to the protective net, when weeding under the skirt member is mowed, if the skirt member is flipped up and temporarily stopped in the standing state, the weeding mowing is performed. The skirt member does not interfere with the work, and the mowing work can be performed smoothly.

Further, the arrangement of the skirt member prevents the animal from jumping at the position close to the protective net, so that the height at which the animal can pass by the jump can be lowered, and it is used accordingly. It is not necessary to set the height of the protective net to be high, and the cost can be reduced by reducing the material for forming the protective net.
