Description

  The present invention relates to a net for a beast harm protection fence used for constructing a beast harm protection fence for preventing a pest such as a wild boar from entering a predetermined area such as a field.

Wild farms such as wild boar inhabit mountain villages, and crops are often eaten and damaged. In order to eliminate this kind of damage, farmers are constructing beast damage protection fences to prevent harmful beasts from entering predetermined areas such as fields.
As a member for constructing this kind of beast damage protection fence, a net-like body having good ventilation and translucency is suitable, for example, crossing a plurality of iron wires vertically and horizontally in substantially the same plane, A network having a structure in which crossing portions are fixed and integrated by welding has been proposed (see, for example, Patent Document 1).

Utility Model Registration No. 3072153

  As shown in FIG. 4, the above net-like body is formed by arranging the vertical iron wires 8 and the horizontal iron wires 9 equally over the entire surface. The spacing p between the iron wires 8 and 8 and the iron wires 9 and 9 The interval q between them is set to a value that cannot pass through the pests.

  However, in the mesh body 10 having the above-described configuration, the vertical and horizontal iron wires 8 and 9 are densely arranged over the entire height and length, so that the weight of the mesh body 10 increases and handling such as transportation is inconvenient. In addition, since the material cost increases, the production cost of the mesh body is high. Furthermore, since the horizontal iron wires 9 are arranged over the entire height, when this net 10 is used for constructing a beast damage protection fence for wild boars, the wild boar sequentially uses the horizontal iron wires 9 from the bottom. Since the net body 10 is climbed as a foothold, there is a problem that the net body 10 is easily overcome.

  This device has been made by paying attention to the above-mentioned problems. In addition to reliably preventing the invasion of harmful animals, a lightweight and inexpensive animal network for fences that can be constructed with a minimum number of materials is required. The purpose is to provide.

The net for beast harm protection fence according to this device is formed by crossing a plurality of wires vertically and horizontally and fixing each crossing portion, and the vertical wire cannot pass through the target harmful beast. At least two horizontal wires are arranged on the upper end side and the lower end side, respectively. The lowermost horizontal wire on the upper end side is disposed at a height that does not reach the foot of the target harmful animal with respect to the uppermost horizontal wire on the lower end side.
In the above-described configuration of the present invention, the “wire” means a linear or rod-like material, and typically an iron wire is used.

  When constructing a beast harm protection fence with a mesh body according to the present invention, since the vertical wires are arranged at intervals at which the target pest (for example, wild boar) cannot pass through, the pests are not spaced between the mesh bodies. Can't go through. Further, at least two horizontal wires are arranged on each of the upper end side and the lower end side, and the lowest horizontal wire on the upper end side is compared to the uppermost horizontal wire on the lower end side. Since the target pest is placed at a height that cannot be reached, even if the pest climbs onto the uppermost horizontal wire on the lower end side, the lowest position on the upper end side from that position The horizontal wire cannot be reached and the net cannot be overcome. Moreover, since at least two horizontal wires are arranged on the upper end side and the lower end side, all the vertical wires are firmly connected at the upper end portion and the lower end portion, so that the overall strength of the net-like body is obtained. And the deformation of the mesh body can be prevented, and there is no possibility that the mesh body will be pierced by harmful animals.

In a preferred embodiment of the present invention, the number of wires in the horizontal direction is set to 2 on the upper end side, and the number of wires on the lower end side is set to 3, and the three horizontal wires on the lower end side are the lowest wires. The distance between the intermediate position wire and the intermediate position wire is set to a value larger than the distance between the intermediate position wire and the uppermost wire.
According to this embodiment, the net-like body can be installed so that the lowest wire is buried at an appropriate depth in the ground near the ground surface, and the lowest horizontal wire is located in the ground near the ground surface. Becomes a hindrance to digging up the soil and can prevent pests from penetrating under the mesh.

  According to this device, it is possible to reliably prevent harmful animals from passing through and over the gaps between the wire rods, and to configure a net for a beast harm protection fence lightly and inexpensively with the minimum number of wires. effective.

It is a front view which shows the structure of a net-like body. It is a perspective view which shows the connection state of the mesh body and support | pillar by a mesh body connection tool. It is a front view which shows the conventional mesh body.

FIG. 1 shows a schematic configuration of a beast harm protection fence constructed by using a mesh body 2 according to an embodiment of the present invention.
The illustrated example of the beast harm protection fence 1 is vertically installed on the ground, and a plurality of mesh bodies 2 and 2 that are successively connected side by side, and a column 3 that is vertically installed on the ground for each position where the mesh bodies 2 are connected. And the mesh body couplers 4 and 4 for integrally coupling the adjacent mesh bodies 2 and 2 to the column 3.
As shown in FIG. 3, the adjacent mesh bodies 2 and 2 are overlapped with the inner end portions 2 </ b> L and 2 </ b> R connected to each other with a slight positional shift. At least one reticulate body connector 4 is disposed at each of the upper and lower positions, and reticulate bodies 2 and 2 are connected in a state where they are overlapped in the front and rear with the support 3 interposed therebetween.

  As shown in FIG. 2, each mesh body 2 has a plurality of wire rods 20 and 21 crossing vertically and horizontally in substantially the same plane, and all the crossing portions are integrally fixed by welding. Hereinafter, the vertical wire 20 is referred to as “vertical wire 20”, and the horizontal wire 21 is referred to as “horizontal wire 21”.

In the reticulated body 2 in the illustrated example, iron wires having a circular cross section of 5 mm in diameter are used as the vertical wire 20 and the horizontal wire 21. In this embodiment, the length of the vertical wire 20 is 1 m and the length of the horizontal wire 21 is 2 m. However, the diameter and length of the iron wire are not limited to this.
The vertical wires 20 are provided at intervals at which the harmful animal cannot pass through. In this embodiment, a wild boar is assumed as a harmful animal, and the arrangement interval t of the vertical wires 20 is set to 75 mm so that a Weifang (wild boar child) cannot pass through.

  The horizontal wire 21 is disposed on the upper end side and the lower end side with a region S in the center of the height. In this embodiment, the number on the upper end side is set to two, and the number on the lower end side is set to three. By arranging at least two each on the upper end side and the lower end side, all the vertical wires 20 are firmly connected at the upper end portion and the lower end portion, so that the overall strength of the mesh body 2 is increased, deformation, etc. Is prevented.

The two horizontal wires 21 on the upper end side have a distance d1 between the upper end of the vertical wire 20 and the upper horizontal wire 21a of 50 mm, and the distance between the upper horizontal wire 21a and the lower horizontal wire 21b. (Interval) d2 is set to 75 mm.
The three horizontal wires 21 on the lower end side have a distance d5 between the lower end of the vertical wire 20 and the lowest horizontal wire 21e of 65 mm, and a distance d4 between the lowest horizontal wire 21e and the horizontal wire 21d at the intermediate position is 150 mm. The distance d3 between the horizontal wire 21d at the intermediate position and the uppermost horizontal wire 21c is set to 75 mm.

  As shown in FIG. 1, each mesh body 2 is vertically arranged so that the lowest horizontal wire 21 e is located in the ground near the ground surface F. Since the lowest horizontal wire 21e is located in the ground near the ground surface F, it becomes an obstacle for the wild boar to dig up the soil, and can be prevented from passing through the lower side of the net 2. The distance d4 between the lowest horizontal wire 21e and the horizontal wire 21d above it is assumed that the lowest horizontal wire 21e is buried in the ground, and the horizontal wire 21d at the intermediate position and the horizontal wire 21c above it. Is set to be larger than the distance d3.

  The height h of the lower horizontal wire 21b on the upper end side with respect to the uppermost horizontal wire 21c on the lower end side does not reach the horizontal wire 21b even if the wild boar rides on the horizontal wire 21c with the rear foot. Such height is set to 660 mm in this embodiment. In this way, there is no horizontal wire that serves as a foothold for the wild boar in the region S in the center of the height between the uppermost horizontal wire 21c on the lower end side and the lower horizontal wire 21b on the upper end side. It is impossible to get over the mesh 2.

  The support column 3 is driven vertically into the ground with the lower end driven deeply into the ground, and it is desirable to sharpen the lower end so that it can be driven into the ground and is easy. Since the support column 3 is driven deeper than the mesh body 2, the length is set to be larger than the height of the mesh body 2 so that the height is substantially aligned with the mesh body 2 when vertically installed. A steel rod having a diameter of 10 to 13 mm is used for the column 3 of this embodiment, and a spiral strip (not shown) may be formed on the outer peripheral surface in order to make it difficult to come out from the ground.

As shown in FIG. 3, the mesh body connector 4 is formed by bending and folding a rectangular rectangular metal plate material at a right angle at the center of the length, and a pair of opposing vertical plate portions 41 and 42. It has the bending board part 40 integrally.
A space surrounded by the vertical plate portions 41 and 42 and the bent plate portion 40 constitutes a wire rod insertion groove 5 into which the support column 3 and the two vertical wire rods 20 and 20 can be inserted. Inside this wire rod insertion groove 5, there are crossed portions of the vertical wire rods 20 </ b> L and the horizontal wire rods 21 of the front mesh member 2 and crossed portions of the vertical wire rods 20 </ b> R and the horizontal wire rods 21 of the back mesh member 2. Since the two horizontal wires 21 and 21 pass through the wire insertion groove 5 and pass through the vertical plates 41 and 42, the wire is inserted at the same position on the lower edge of each vertical plate 41 and 42. Two notched grooves 43 and 44 having a groove width capable of passing through the horizontal wire members 21 and 21 intersecting with the longitudinal wire members 20L and 20R before and after passing through the inside of the groove 5 are provided.

  The beast damage protection fence 1 having the above-described configuration is configured by sequentially connecting a plurality of mesh bodies 2 side by side. For the assembly, first, the support pillars 3 are grounded corresponding to the positions where the mesh bodies 2 are connected side by side. Drive vertically and install vertically. Next, after positioning the two mesh bodies 2, 2 connected side by side in a state where the inner end portions 2 </ b> L, 2 </ b> R overlap each other with the support 3 interposed therebetween, each mesh body 2 is connected by the mesh body connector 4. , 2 are connected to the support column 3 integrally. In the illustrated example, the mesh body connector 4 is installed at the position of the upper horizontal wire 21a on the upper end side and at the position of the uppermost horizontal wire 21c on the lower end side. You may install the mesh body coupling tool 4 also in the position of 21b and the position of the other horizontal wire 21d of a lower end side.

  When the beast harm protection fence 1 is constructed in this way, the vertical wires 20 are arranged at intervals t that cannot pass through the target beast (for example, wild boar). Can't pass through the gap. In addition, at least two horizontal wires 21 are arranged on each of the upper end side and the lower end side, and the lowest horizontal wire 21b on the upper end side is the target with respect to the uppermost horizontal wire 21c on the lower end side. Since the pests are disposed at a height that cannot be reached by the pests, even if the pests ride on the uppermost horizontal wire 21c on the lower end side, the lowermost horizontal wire 21b on the upper end side from that position. The foot cannot reach the foot and the foot or the toenails cannot be hooked, so the net 2 cannot be overcome. Moreover, since at least two horizontal wires 21 are arranged on each of the upper end side and the lower end side, all the vertical wires 20 are firmly connected at the upper end portion and the lower end portion, and the overall strength of the net-like body 2 is increased. The deformation of the reticulate body 2 can be prevented, and there is no possibility that the reticulate body 2 is broken through by a harmful animal.
