Description

The present invention relates to a direction guidance device for preventing harmful behavior of designated controlled birds and animals such as wild boars and deer to farmland and earth structures, and for guiding the direction of movement of designated controlled birds and animals.

In recent years, environmental changes are progressing in middle and mountainous areas, from the outer edges of plains to mountainous areas, as the population declines and lifestyles change, resulting in an increase in abandoned cultivated land and widespread abandonment of the use of forests and fields. Hilly and mountainous areas, where the environment has changed, have become suitable habitats for large animals such as wild boars and deer, providing food, shelter, water, etc., resulting in an expansion of the population and distribution area of large animals. . The increase in large animals is causing a variety of problems, including feeding damage to farmland, damage to humans (biting, parasites, etc.), and damage to earth structures such as embankments, embankments, and embankments.

In particular, harmful behaviors such as wild boars digging up plant roots and insects (larvae) on slopes in order to prey on earthen structures are increasing. The toe of the slope is an extremely important part for slope stability, and looseness in this part increases the risk of slope failure. For similar reasons, wild boars have also caused damage to stone walls.

In order to prevent the spread of damage caused by such large animals, the Ministry of Agriculture, Forestry and Fisheries and the Ministry of the Environment have amended the previous Wildlife Protection Act to implement designated management methods that allow the capture of wild boars and deer in appropriate amounts. We are currently exterminating them as wild animals, but as a result, wild boars that used to live in the mountains, which have become a new hunting area, have moved to urban areas, so although the number of wild boars has decreased, they are now being exterminated outside the agricultural field. The damage is increasing.

Conventionally, various intrusion prevention measures have been taken to prevent designated controlled birds and animals from entering protected areas such as farmland and earthen structures. For example, conventional intrusion prevention measures include enclosing a protected area with a metal fence or synthetic resin net to prevent the intrusion of designated controlled birds and beasts (for example, see Patent Documents 1 and 2), sensor lights, etc. A device that uses light emitted from a synthetic resin net with a luminescent function, electric shock, etc. to give a sense of discomfort or fear to designated managed birds and animals to prevent them from entering a protected area (for example, Patent Document 3, 4), and methods for exterminating designated controlled birds and beasts using traps (for example, see Patent Document 5).

Japanese Patent Application Publication No. 2001-008604 Japanese Patent Application Publication No. 2008-187951 Japanese Patent Application Publication No. 2000-194927 Utility model registration No. 3172053 Japanese Patent Application Publication No. 2014-083049

Conventional intrusion prevention technology is often aimed at preventing agricultural damage, and requires a large amount of money to install because the equipment must be strong enough to prevent it from being destroyed by hungry boars in front of the crops. Not only does this require a lot of time and effort, but the running costs are high, such as checking for damage to metal fences and nets, and maintaining the electrical equipment used to deliver electric shocks. In addition, since the installation cost of conventional intrusion prevention measures is high, the amount of damage incurred when the equipment is damaged by designated controlled birds and beasts is also large. Another problem is that large-scale facilities place restrictions on the movement of people and vehicles.

In addition, strong stimulation such as high voltage to enhance the function of preventing wild boar intrusion may not only result in cruelty to wild animals, but also lead to serious disasters (fatal accidents) due to human contact.

Furthermore, in recent years, not only earth structures such as embankments and embankments, but also hard ground such as bedrock, crushed stone embankments, and concrete surfaces have been dug up, resulting in a rapid increase in damage caused by falling rocks and landslides. There is a growing need for Similarly, it is necessary to take measures to prevent intrusion in places with harsh environments such as slopes and bushes.

On the other hand, in vocational facilities, the work that people with disabilities can perform is limited, so there are many cases where the work is contracted out at extremely low wages, and even the minimum wage set by the local government is not paid because the person is disabled. Social problems are occurring, such as parents of people with disabilities having great anxiety about their future.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide a direction guidance device for designated birds and beasts that can prevent the invasion of designated birds and beasts at a low cost and can be installed in a variety of locations.

In order to solve the above problem, the invention of claim 1 is a net arranged to prevent the intrusion of designated managed birds and beasts, and has a curled part whose end part is wound into a cylindrical shape. A protective net whose other parts are arranged above the ground by a predetermined height, and a string-like elastically deformable string disposed within a curled portion of the protective net, with both ends protruding from the end of the curled portion. The protection net is provided with a support string and an anchor that can be driven into the ground by striking, and by connecting the anchors to both ends of the support string and driving the anchors into the ground, the protective net can be driven into the ground. This is a direction guidance device for designated managed birds and animals that is installed.

According to a second aspect of the present invention, in the direction guidance device according to the first aspect, the support string is connected to a curled portion of the protective net.

According to a third aspect of the present invention, in the direction guiding device according to the first aspect, the support string is disposed within the curled portions of the plurality of protective nets, and the support string is connected to each of the curled portions. It is characterized by

According to a fourth aspect of the invention, in the direction guidance device according to any one of claims 1 to 3, an annular connecting portion is formed by binding at two or more places at both ends of the support string, and the anchor is inserted into the connecting portion. Accordingly, the anchor is connected to both ends of the support string.

According to a fifth aspect of the present invention, in the direction guiding device according to any one of claims 1 to 4, the anchor includes an anchor body that is rod-shaped and has a pointed end at one end and is driven into the ground, and the other end of the anchor body. and a cap covering the.

The invention according to claim 6 is the direction guidance device according to claims 1 to 5, in which the mesh of the protection net is capable of inserting the foot of the designated bird or animal under management, and the foot of the designated bird or beast can be inserted through the mesh. It is characterized in that the size is set so that it gets caught on the foot when trying to pull it out.

Artiodactyls, such as wild boars and deer, which are designated as designated controlled birds and animals, have two main hooves at the tips of their feet and two secondary hooves on the rear side slightly above the main hooves. They tend to dislike things that get stuck between their hooves, or anything that might get their feet caught between them. Additionally, boars and deer can see their front legs but not their hind legs, so they cannot consciously control where they place their hind legs.

According to the invention described in claim 1, since the protective net is arranged at a predetermined height from the ground, if a boar or deer enters the device, its front legs will be inserted into the mesh of the protective net. There is a high probability that you will experience phenomena such as getting entangled, bending your legs, and losing your balance. Furthermore, if the protective net gets caught between the main hoof and the secondary hoof, it can cause discomfort to boars and deer. Even if the front feet are able to enter and land safely, the hind feet, which are in a blind spot and cannot consciously control where they land, are more likely to get tangled in the protective net than the front feet, and are protected between the main and secondary hooves. The net will get caught. Therefore, although it has a very simple configuration of installing a protective net at a predetermined height above the ground, it can effectively prevent designated managed birds and beasts from entering the protected area, and can prevent designated birds and animals from entering the protected area. It is possible to guide the movement direction of designated managed birds and beasts.

In addition, since only the curled part of the end of the protective net is placed into a cylindrical shape, and the other parts are placed above the ground at a predetermined height, the configuration is simplified and production and maintenance costs can be reduced. It becomes possible. Moreover, the curled portions are simply formed by processing the protective net itself, and no other members are required, so that the cost of members can be reduced and installation can be done easily and in a short time. Furthermore, the protective net can be easily and appropriately positioned at a desired height by simply changing the size (cylinder diameter) of the curled portion. Furthermore, since the end portion of the protective net is simply rolled into a cylindrical shape, the curled portion can be manufactured by hand-crafting.

On the other hand, the protective net can be installed by simply connecting an expandable and deformable support cord to the curled portion, connecting anchors to both ends of the cord, and driving the anchor into the ground. Therefore, it is possible to easily, quickly, and appropriately install the protective net in a variety of locations, such as hard ground such as bedrock or crushed stone embankment, or locations with harsh environments such as slopes and bushes.

In addition, because the support strings are elastic and deformable, even if a designated controlled bird or animal with its feet entangled in the protective net struggles, the support strings will simply expand, contract, or deform and restore its original shape, allowing its feet to be removed from the protective net. Hard to come off. As a result, it becomes possible to more effectively prevent the designated controlled birds and beasts from entering the protected area, and it also becomes possible to prevent and suppress damage to the support string and also to the present device.

According to the invention described in claim 2, the support string is connected to the curled portion of the protective net, and the protective net and the support string are integrated in advance, so that the protective net, that is, the main direction guidance device can be operated more easily and quickly. And it becomes possible to install it appropriately. Moreover, since the support string is simply connected to the curled portion, the work is easy and can be manufactured by hand-picking.

According to the invention described in claim 3, the support string is connected to each curl part of the plurality of protective nets, and the plurality of protective nets are integrated in advance via the support string, so that the plurality of protective nets can be connected more easily. It becomes possible to install easily, quickly and appropriately. It is particularly difficult to work in places with harsh installation environments such as slopes or bushes, but even in such places it can be installed easily, quickly and properly, reducing the burden on workers. Become.

According to the invention described in claim 4, a tensile force acts on the expandable and deformable support string, and the cross-sectional contraction of the support string prevents the binding force from weakening and the fixed ends from unraveling, and the protective net, that is, the main direction guidance. It becomes possible to install the device more reliably.

According to the invention set forth in claim 5, since the anchor has a simple configuration that only includes an anchor body and a cap, manufacturing costs and maintenance costs can be reduced. Moreover, since the other end of the anchor body is covered with a cap, it is possible to prevent the other end of the anchor body from injuring people and designated controlled animals and animals, thereby ensuring safety.

According to the invention set forth in claim 6, since the size of the mesh of the protection net is set to an appropriate size, it is possible to reliably catch and entangle the legs of designated managed birds and animals.

The present invention will be described below based on the illustrated embodiments.

1 to 8 show an embodiment of the present invention, and FIG. 1 shows a state in which a plurality of direction guidance devices (hereinafter referred to as "direction guidance devices") 1 for designated management birds and beasts according to this embodiment are installed. FIG. This direction guidance device 1 is installed, for example, along a concrete surface portion 102 at the bottom of a slope 101 near a mountain road. Designated controlled birds and animals such as wild boars M and deer appear on the slope 101 and dig up the slope 101 in order to prey on earthworms and plants growing on the slope 101. For this reason, the direction guiding device 1 prevents the designated controlled birds and beasts from entering the slope 101, and guides the designated controlled birds and beasts to a place other than the slope 101, which is a protected area. Here, in this embodiment, the case where the designated managed bird and beast is a boar M will be mainly described below.

As shown in FIG. 2, this direction guiding device 1 mainly includes a protective net 2, a support string 3, and an anchor 4.

As shown in FIG. 3, the protective net 2 is a net or mesh body that is placed in or near a protected area where the intrusion of the wild boar M is prevented, and in this embodiment extends substantially laterally on the concrete surface 102. By having the curled portion 21 at the end, the portion other than the curled portion 21 is placed above the ground G by a predetermined height. That is, the mesh is made of plastically deformable synthetic resin and is formed into a substantially rectangular shape.As shown in FIG. is formed. That is, the curled portions 21 are formed on two opposing long sides of the substantially rectangular net body, and the space between the curled portions 21 is formed in an arch shape.

The curled portion 21 is such that the portion other than the curled portion 21 is positioned above the ground G by a predetermined height, and is formed by winding the end portion of the protective net 2 into a cylindrical shape. Further, the size and outer diameter of the curled portion 21 are set such that the portion other than the curled portion 21 is located above the ground G by at least a predetermined height, and as a result, the height H of the central portion 22 is set to a predetermined height. It is taller than the height. Here, the predetermined height is set to a height that allows the foot M1 of the boar M to be captured more reliably when the boar M steps into the protective net 2, as shown in FIG.

Further, as shown in FIG. 6, the mesh 2a of the protective net 2 is such that the foot M1 of the boar M can be inserted thereinto, and when the foot M1 of the boar M is to be removed from the mesh 2a, the protective net 2 is inserted into the foot M1. The size is set so that it can be caught on. The details will be described later, but for example, it is formed into a square or rectangle with each side measuring 2 to 5 cm. Note that the shape of the mesh 2a may be a polygon other than a square or a rectangle, or may be a triangle, a circle, or an ellipse.

The support string 3 is in the form of a string that is expandable and deformable, and is disposed within the curled portion 21 of the protective net 2, with both ends protruding from the end of the curled portion 21. In this embodiment, there are four supporting strings. It is disposed within the curled portion 21 of (a plurality of) protective nets 2. In other words, even if the boar M, which is composed of a rubber cord and has its foot M1 entangled in the protective net 2, struggles, the support cord 3 will expand and contract without breaking, and the foot M1 will not easily come off from the protective net 2. The elasticity, elastic deformability, and viscosity of the rubber string are set. Then, as shown in FIG. 2, with the four protective nets 2 arranged so that the curled parts 21 are coaxial, the support string 3 is arranged to pass through both the four-rowed curled parts 21. has been done.

Such a support string 3 is connected to the curl portion 21 of each protective net 2 in advance. That is, in this embodiment, as shown in FIG. 7, one end of the first binding band 51 is inserted into the curled part 21 through the mesh 2a of the curled part 21, wrapped around the support string 3, and released outside the curled part 21. By pulling out and tightening the first binding band 51, the support string 3 is connected and fixed to the curled portion 21. Such connections are made at a plurality of locations on the curled portions 21 of each protective net 2, thereby connecting and integrating the four protective nets 2 via the support strings 3. That is, in this embodiment, four protective nets 2 constitute an integrated direction guidance device 1. Here, the connection position and number of connections by the first binding band 51 and the size (width, thickness) of the first binding band 51 are such that even if the boar M struggles with his leg M1 entangled in the protective net 2, The connection between the support string 3 and each protection net 2 is set so as not to be broken.

Further, as shown in FIG. 2, both ends of the support string 3 protrude from the ends of the curled portions 21 of the protective net 2 disposed at both ends, and an annular connecting portion 31 is formed by binding at two or more places. ing. That is, as shown in FIG. 8, the end portion of the support string 3 is folded back and the overlapped portion is fixed with the second binding band 52 and the third binding band 53, so that the annular connecting portion 31 is It is formed. Here, the size (inner diameter) of the inside of the ring of the connecting part 31 is set so that an anchor main body 41 of the anchor 4 described later can be inserted therein, and does not come off from the cap 42 of the anchor 4. Further, in this embodiment, the connecting portion 31 is formed by two binding bands 52 and 53, but it may be formed by three or more binding bands.

The anchor 4 is a driven pile that can be driven into the ground by impact, and includes an anchor body 41 and a cap 42, as shown in FIG. The anchor body 41 is a round steel rod (reinforcing bar shape) that is driven into the ground, and has a pointed end 41a formed at one end, and an annular rib 41b protruding from the outer peripheral surface along the axial direction. A plurality of them are formed at predetermined intervals. This makes it difficult for the ribs 41b to bite into the concrete surface portion 102 and the anchor body 41 to come off. Here, the outer diameter, length, strength, and rigidity of the anchor body 41 are such that it can be driven into hard ground such as the concrete surface part 102, bedrock, and crushed stone embankment. Also, the anchor body 41 is set so as not to come off.

The cap 42 is a plastic lid that covers the other end (the opposite end 41a) of the anchor body 41. That is, it has a cylindrical shape with a closed top, and the other end of the anchor body 41 can be press-fitted therein. In addition, the upper part has a large diameter and is shaped like a rounded dumpling, so that it will not be damaged even if it is hit by a person or designated controlled wildlife.

Then, by inserting the anchor body 41 into the connecting portion 31 of the support string 3, the anchor 4 is connected to the end of the support string 3. In this way, by connecting the anchors 4 to both ends of the support string 3 and driving the anchor 4, that is, the anchor body 41 into the ground from the tip 41a side, the protective net 2 is connected to the ground ground via the support string 3. will be installed in Thereafter, safety is ensured by attaching the cap 42 to the other end of the anchor body 41.

Next, the operation of the direction guidance device 1 having such a configuration and the direction guidance method for designated management birds and animals using the direction guidance device 1 (hereinafter referred to as "direction guidance method") will be explained.

First, as shown in FIG. 1, a required number of direction guidance devices 1 are installed on the concrete surface section 102. That is, by placing the curled portions 21 of the four integrated protective nets 2 against the ground G, the protective net 2 is placed at a position above the ground G by a predetermined height so as to extend substantially laterally. do. Next, insert the pointed end 41a side of the anchor main body 41 of the anchor 4 into the connecting part 31 of each support string 3, put the pointed end 41a against the ground G, and then press the other end and upper part of the anchor main body 41 with a hammer or the like. The anchor body 41 is driven into the ground by striking, and the four integrated protection nets 2 are arranged and fixed on the ground G. Thereafter, a cap 42 is attached to the other end of each anchor body 41. In this way, the required number of direction guidance devices 1 are installed at the required locations. Here, although FIG. 1 shows a state in which three direction guidance devices 1 are arranged in parallel in the width direction (short direction) of the direction guidance device 1, one, two, or four or more direction guidance devices 1 are arranged in parallel in the width direction (short direction). The direction guidance device 1 may be arranged, or a plurality of direction guidance devices 1 may be arranged in parallel in the longitudinal direction (longitudinal direction).

With the direction guidance device 1 disposed in this manner, the boar M appears on the slope 101 and the concrete surface 102 in order to prey on earthworms living on the slope 101 and plants growing on the slope 101. Then, as shown in FIG. 5, when the boar M steps foot M1 onto the concrete surface portion 102, the foot M1 is inserted into the mesh 2a of the protective net 2. As shown in FIG. 6, the artiodactyl foot M1 of the boar M has two main hooves M1a at the tip, and has a soft expanded portion M1b at the rear upper part of the main hoof M1a. Moreover, two accessory hooves M1c are present at the upper part of the expansion part M1b.

In the protective net 2 into which the foot M1 is inserted, the mesh 2a is entangled with the upper part of the secondary hoof M1c, and is caught between the main hoof M1a or between the foot M1 and the secondary hoof M1c. Boar M has a habit of hating things that get caught between the main hoof M1a and secondary hoof M1c, or anything that might get the leg M1 itself caught, so the boar M raises and lowers the leg M1 in an attempt to remove the leg M1 from the protective net 2. I do things. However, the foot M1 does not easily come out of the protective net 2 because the protective net 2 is caught on the expanded portion M1b of the foot M1 and is sandwiched between the main hoof M1a and the secondary hoof M1c. Therefore, the uncomfortable state for the boar M is maintained, and the boar M gives up on entering the slope 101 and changes its direction of movement.

As described above, according to the direction guidance device 1 and the direction guidance method, since the protective net 2 is arranged at a predetermined height from the ground G, when the boar M enters the device 1, the foot M1 is There is a high probability that the user will experience phenomena such as being inserted into the mesh 2a of the protective net 2 and becoming entangled, causing the leg M1 to bend and causing loss of balance. Furthermore, the protection net 2 being caught between the main hoof M1a and the secondary hoof M1c can also make the boar M feel uncomfortable. Even if the front foot M1 were to successfully enter and land, the hind foot M1, which is in a blind spot and cannot consciously control its landing place, would have an even higher probability of getting entangled in the protective net 2 than the front foot M1, causing the main hoof M1a and secondary foot M1 to become entangled. The protective net 2 will be sandwiched between the hooves M1c. Therefore, although the protection net 2 has a very simple configuration in which the protection net 2 is installed at a predetermined height above the ground G, it is possible to effectively prevent designated managed birds and animals from entering the protected area, and to protect the protected area. It is possible to guide the movement direction of designated managed birds and beasts. Furthermore, since the size of the mesh 2a of the protective net 2 is set to an appropriate size, it is possible to reliably catch and entangle the foot M1 of the boar M.

In addition, since only the curled portion 21, which is the end of the protective net 2 wound into a cylindrical shape, and the other portions are placed above the ground G by a predetermined height, the configuration is simplified and manufacturing and maintenance costs are reduced. It becomes possible to do so. Moreover, since the curled portion 21 is simply formed by processing the protective net 2 itself, and no other members are required, the cost of the members can be reduced and installation can be done easily and in a short time. Furthermore, by simply changing the size (cylinder diameter) of the curled portion 21, the protective net 2 can be easily and appropriately positioned at a desired height. Furthermore, since the end portion of the protective net 21 is simply rolled up into a cylindrical shape, the curled portion 21 can be manufactured by hand-crafting.

On the other hand, a support string 3 that is expandable and deformable is disposed within the curled portion 21, and the protective net 2 can be installed by simply connecting anchors 4 to both ends of the support string 3 and driving the anchors 4 into the ground. can. Therefore, it is possible to easily, quickly and appropriately install the protective net 2 in various places such as hard ground such as bedrock or crushed stone embankment, or places with harsh environments such as slopes and bushes. Moreover, since the anchors 4 can be driven into hard ground, the protective net 2 can be installed not only on earth structures such as embankments and embankments, but also on hard ground such as concrete surfaces 102 and crushed stone embankments, to prevent intrusion such as wild boars M. This makes it possible to prevent

In addition, since the support string 3 is expandable and deformable, even if the boar M with its foot M1 entangled in the protective net 2 struggles, the support string 3 will only expand and contract or deform and recover, and the foot M1 will be restored. is difficult to escape from the protective net 2. As a result, it becomes possible to more effectively prevent the designated controlled birds and beasts from entering into the slope 101, and it also becomes possible to prevent and suppress damage to the support string 3 and further to the device 1. .

In addition, since the support string 3 is connected to the curled portion 21 of the protective net 2 and the protective net 2 and the support string 3 are integrated in advance, the protective net 2, that is, the main direction guiding device 1 can be operated more easily, quickly and properly. It becomes possible to install it in Moreover, since the support string 3 is simply connected to the curled portion 21 with the first binding band 51, the work is easy and can be produced by hand-picking.

Furthermore, since the support string 3 is connected to each curl part 21 of the plurality of protective nets 2, and the plurality of protective nets 2 are integrated in advance via the support string 3, it is easier and faster to connect the plurality of protective nets 2. And it becomes possible to install it appropriately. It is particularly difficult to work in places with harsh installation environments such as slopes or bushes, but even in such places it can be installed easily, quickly and properly, reducing the burden on workers. Become.

In addition, the anchors 4 are connected to both ends of the support string 3 by simply inserting the anchors 4, that is, the anchor bodies 41, into the connecting portions 31 at both ends of the support string 3. It becomes possible to install it more easily, quickly and properly. In addition, since the connecting portion 31 is formed by binding at two or more places, a tensile force acts on the expandable and deformable support string 3, and the cross-sectional contraction of the support string 3 weakens the binding force and causes the fixed end to come undone. Therefore, the protective net 2, that is, the main direction guidance device 1 can be installed more reliably.

Furthermore, since the anchor 4 has a simple configuration that only includes the anchor body 41 and the cap 42, manufacturing costs and maintenance costs can be reduced. Moreover, since the other end of the anchor body 41 is covered with the cap 42, it is possible to prevent the other end of the anchor body 41 from injuring people or designated managed birds and animals, thereby ensuring safety.

Although the embodiments of this invention have been described in detail above, the specific configuration is not limited to this embodiment, and even if there are changes in the design within the scope of the gist of this invention, Included in invention. For example, in the embodiment described above, the anchor body 41 is made of a reinforcing rod, but other structures may be used depending on the ground into which the anchor is to be driven. Alternatively, the protective net 2, the support string 3, and the anchors 4 may be integrated in advance by connecting and fixing the anchors 4 to both ends of the support string 3 in advance. This makes it possible to install the direction guidance device 1 more easily, quickly and appropriately even in places with harsh environments. Furthermore, adjacent protective nets 2 may be connected to each other with a binding band or the like, thereby making it possible to further prevent the protective nets 2 from being damaged or removed.
