Description

  The present invention is a quadruped beast (hereinafter referred to as the following), such as moths, deer, moths, wild dogs, etc. that may cause damage to grains, vegetables, fruits, etc. (hereinafter referred to as crops) cultivated in the field. It is related to the structure used to keep it away from crops.

  Conventionally, as a method of protecting crops from damage by harmful animals, it has been a common method to provide a fence with a predetermined height around the field. In addition, when the fence is made of metal, a method of further increasing the effect of preventing invasion of harmful animals by flowing electricity through the metal fence is also performed.

  With respect to the fence, in the “Structure for Pest Invasion Prevention and Pest Invasion Prevention Method” of Patent Document 1, it is considered that the fence is doubled to further prevent intrusion from the pest.

JP-A-2006-93124

  In order to install conventional fences around fields, etc., fence materials (hereinafter referred to as fence materials) that are made of metal nets or grids and have a predetermined size (area) are commercially available. However, in order to make the fence material stand upright with respect to the ground, it is necessary to use a support column and to fix the fence material to this.

  And, as a general method, the depth is such that a predetermined strength can be obtained against an external force such as a wind or a harmful animal even if a number of support columns are fixed around a field or the like at predetermined intervals. The problem that it is necessary to work on all of the struts, as well as the work of driving into the ground and the work of fastening the fence material to one strut with at least two wires or dedicated metal fittings etc. was there.

  The fact that the fence is fixed to the ground means that, in the weeding work that is indispensable in the farmland and the forest for cultivating crops, a circular blade that is commonly used is rotated by an engine or motor. Working with a mower has a problem that it is difficult to work because it is necessary to pay attention to the damage of the circular blade. For this reason, there was a problem in the vicinity of the fence that herbicides that had to be considered for crops were used or that weeding was done manually.

  In addition, the effective height of the fence is required to be at least about 1m to prevent the pests from jumping over. However, there is a problem that it is necessary to provide a door at one place or a plurality of places of the fence so as to be convenient for work.

  Also in “Structure for Pest Invasion Prevention and Pest Invasion Prevention Method” of Patent Document 1, the paragraph [0063] of the specification also states “In addition to land that prevents the invasion of pests such as fields and forests”. When a person needs to enter, the structure for preventing pest invasion according to the present invention is installed around the land, and a part of the periphery is left open, and an entrance is provided in that part. " As it was, there were similar problems.

  Regarding the “pest invasion prevention structure and pest invasion prevention method” of Patent Document 1, since a framework composed of a plurality of parts is manufactured so as to have a certain strength, a wire mesh is attached on the structure. However, since a complicated structure for preventing pest intrusion must be created by collecting a large number of materials, there is a problem that the structure for preventing pest intrusion is expensive and the number of steps for producing the structure is increased.

  Regarding the “pest invasion prevention structure and pest invasion prevention method” of Patent Document 1, although fixing to the ground is not described, the provision of the aforementioned entrance / exit, paragraph [0010] of the specification, According to the effect of the invention, because it is a structure with a height and width, compared to a known pest prevention fence, for example, a pest that jumps like a deer and invades the ground like a wild boar It is also difficult to invade harmful beasts that dig up and invade. ”As an embodiment of paragraphs [0066] to [0068] of the specification, the structure of Patent Document 1 is high. This is described as a frame width of 1 m. Therefore, even if it is not fixed to the ground, its weight or size is not the weight or size that can be moved by an adult 1 and cannot be easily moved. There was a problem.

  Furthermore, in the “pest invasion prevention structure and pest invasion prevention method” of Patent Document 1, a space having a width of 1 m inside the pest invasion prevention structure is provided, so a general fence There was a problem that it was more difficult to weed in comparison with.

  In order to solve the above problems, the present invention takes the following technical means.

  The beast repellent structure according to the first aspect of the present invention has a delimiter in which the size of the demarcated hole is larger than the tip size of the limb of the beast to be repelled by providing a predetermined margin, and the effective number in the width direction of the delimiter is determined. Three or more rectangular grid plates are used, and the installation height of the square grid plates is set within a range based on the length of the limb of the beast to be avoided.

  The animal repellent structure according to a second aspect of the present invention is the invention according to the first aspect, wherein the lattice plate is formed in a substantially horizontal shape, an oblique shape, a mountain shape, an arc shape or a combination thereof with respect to the ground. Has been.

  The animal repellent structure according to a third aspect of the present invention is formed by bending one grid-like plate in the invention according to the first or second aspect.

  The animal repellent device according to the fourth aspect of the present invention is formed by using a plurality of animal repellent structures according to claims 1 to 3 and arranging them around the crop to be protected.

  Having the technical means as described above has the following effects.

  According to the first invention, since it is not necessary to fix to the ground as in the case of a fence, the installation can be easily performed.

  An embodiment of a beast repellent structure according to the present invention will be described with reference to FIGS. Note that the present invention is not limited to the embodiments.

(First embodiment)
A first embodiment will be described with reference to FIGS. 1 to 5. FIG. 1 is a perspective view showing the appearance of the beast repellent structure 1. When installed on the ground, the beast repellent structure 1 is formed by a top surface 11 that is roughly horizontal to the ground, and a left side surface 12 and a right side surface 13 that extend from both long sides of the top surface 11 toward the ground. ing. The beast repellent structure 1 is formed by a lattice-like plate 20 which will be described in detail later, and the boundary of each surface is not clear. Therefore, the bottom view of FIG. The reference external shape is shown.

  Further, the left side surface 12 and the right side surface 13 do not extend perpendicularly to the top surface 11 but are set to have an obtuse angle in the range of 95 to 115 degrees. By making the obtuse angle, when a plurality of beast repellent structures 1 to be described later are connected and a plurality of beast repellent structures 1 are installed in a ring shape, the beast repellent structures 1 can be overlapped with each other.

  As for the top surface 11, in this embodiment, the height of the top surface 11 with respect to the ground is roughly 150 mm by adjusting the lengths of the left side surface 12 and the right side surface 13 in the height direction. Forming. The height of the top surface 11 with respect to the ground is set based on the length of the limb (also referred to as a leg) of the beast to be avoided (a harmful beast that is supposed to enter). , It is set for adult pupae that live in Japan. It is said that the height of the shoulder is about 600 mm to 900 mm for adult pupae inhabiting in Japan, and the leg length can be estimated to be about 300 mm to 450 mm. Therefore, depending on the beast to be repelled, it may be 50 mm to 300 mm.

The reason why the beast repellent structure 1 has the beast repellent effect is considered as follows.
Unlike the bipedal human being, many of the limbs of the animals that are quadruped walking, which are target animals to avoid, have a structure in which only the fingertips and toes of the hand are attached to the ground. For this reason, the limb of an animal that walks on four legs generally has a smaller installation area with respect to the ground at the tip of the limb than the thickness of the limb. Also, in the vicinity of the extremities of animals walking on quadrupeds, only the parts corresponding to the fingertips and toes of human hands are attached to the ground, and the upper joints of the parts corresponding to the fingertips and toes of human hands are also large. I am walking using it. When external force is applied to the limbs above the upper joints of the parts corresponding to the fingertips and toes of human hands, it is difficult for animals to walk on a quadruped, and the target beast is a beast repellent structure. It is thought that it will not be close to body 1.

  Even for humans, in sporting competitions such as athletics and athletic events, it is necessary to be very careful to walk so as not to be caught by a leveled ladder or an open net. Even in the case of biped walking, this is a difficult movement. Therefore, even if it is agile compared to humans, one of the four limbs is involved in the beast repellent structure 1 for a quadruped walking animal. If it happens, walking becomes difficult.

  The height of the beast repellent structure 1 is about 150 mm, and the width of the repelling range to be installed is about 600 mm. It is also possible. However, the evasion target animals come close to the fields and forests where the crops are planted to eat the crops in the fields and forests at night when humans are not working. Since it moves slowly with vigilance, it is considered that it does not approach this when the beast repellent structure 1 is found or touched.

  In fact, when the applicant installed and implemented a plurality of beast repellent structures 1 of the present embodiment around a field or a forest where the crops were planted, the damage to the crops was reduced.

  The manufacturing method of the beast repellent structure 1 is demonstrated using FIG. The beast repellent structure 1 is formed by processing the square lattice-like plate 20 shown in FIG. The square grid-like plate 20 includes 14 first metal bars 21 (21a to 21n) having a length of 1 m, such as iron or stainless steel plated with a diameter of 5 mm, and a second metal bar 22 (22a having a length of 2 m). ˜22 g) and 7 metal rods.

  As a forming method, the first metal rod 21 and the second metal rod 22 are arranged at roughly equal intervals and welded to each other to form a plate having an overall size of 1 m in length and 2 m in width. As a result, the grid plate 20 has six sections 23 in the vertical direction and thirteen in the horizontal direction. And the front-end | tip of the 1st metal rod 21 (21a-21n) has protruded outside the 2nd metal rod 22a and the 2nd metal rod 22g of both ends. At the same time, the tips of the second metal rods 22 (22a to 22g) protrude outward from the first metal rod 21a and the first metal rod 21n at both ends.

  Here, since the lattice is a periodically arranged partition or partition, in the present embodiment, it is described that a rough square partition is provided, but a triangle, a rectangle, a diamond, A hexagon or the like or a combination of these combinations may be used. And these division | segmentation should just be made into the magnitude | size which provided the predetermined allowance and enlarged on the basis of the front-end | tip size of the leg (leg) of the avoidance target beast (harmful beast in which invasion is assumed). Specifically, adult beasts that live in Japan are set as targets, and in this embodiment, the partition 23 is roughly 150 mm × rough 150 mm. For example, depending on the target animal to be avoided, rough 50 mm × rough 50 mm˜ You may change into the range of coarse 200 mm x coarse 200 mm.

  In FIG. 2 (b), on the long side of the grid plate 20, there are 14 first metal rods 21 that protrude outward from the second metal rod 22a and the second metal rod 22g at both ends of the grid plate 20 ( 21a to 21n) are bent with the second metal rod 22a and the second metal rod 22g at both ends as axes, and are wound around the second metal rod 22a and the second metal rod 22g at both ends. By winding the tips of the 14 first metal rods 21 around the second metal rod 22a and the second metal rod 22g, the processing strength of the lattice plate 20 itself increases, or after the lattice plate 20 is processed. This is because when the strength against twisting or bending of the beast repellent structure 1 is increased, the strength of the tip in contact with the ground is improved and the tip is less likely to sink into the ground.

  In FIG. 2 (c), after bending the tips of the 14 first metal bars 21, the second metal bars 22b and the vicinity of the second metal bars 22a are bent from both sides of the lattice plate 20a. The two first metal rods 21 (21a to 21n) are bent downward. Accordingly, the left side surface 12 and the first metal rod 21a, the first metal rod 21a, the first metal rod 21a, the first metal rod 21a, the first metal rod 21a, the first metal rod 21a, the second metal rod 22a, The right side surface 13 is formed by 13 divisions 23 formed by being surrounded by the one metal rod 21n, the second metal rod 22f, and the second metal rod 22g.

  And the remaining parts, the first metal bar 21a, the first metal bar 21n, the second metal bar 22b and the 52 metal parts 22f that can be surrounded by the second metal bar 22f (4 rows x 13 pieces), A top surface having a length direction of 2 m and a width direction roughness of 600 mm is formed.

  In addition, about the bending angle in the case where the second metal rod 22b and the vicinity of the second metal rod 22a are bent, and both sides of the 14 first metal rods 21 (21a to 21n) are bent downward, as described above. It does not bend to a right angle like Thereby, the beast repellent structure 1 is completed.

  The bending of the beast repellent structure 1 can be performed by a manual operation using a commercially available tool or a dedicated tool that matches the shape of the lattice plate 20. Of course, in mass production, it may be machined by combining a dedicated jig with a press machine or hydraulic bender. Of course, the present embodiment can also be implemented by a method of forming the beast repellent structure by cutting at an appropriate place without bending the grid-like plate 20 and welding, welding, bonding, wire binding, or the like. Problems such as increase, welding, and tying down the strength of the beast repellent structure and distortion occur. Therefore, the convenience of installation may be by a method such as welding, but it is preferable to bend the single lattice plate 20 as it is, as in this embodiment.

  FIG. 3 is a view (side view) of the beast repellent structure 1 as viewed from the width direction of FIG. 1 (hereinafter referred to as the width side). For reference, a shark 8 is shown as a beast to be avoided. When viewed from the side, the beast repellent structure 1 is open to the ground 9 side and has a trapezoidal shape with the ground 9 as the bottom. Further, the top surface 11 is provided with four rows of partitions 23 in a range where the length on the width side is about 600 mm.

  The height of the beast repellent structure 1 is about 150 mm. Therefore, it is possible to easily jump over the beast repellent structure 1 having a height of about 150 mm and a width of about 600 mm if it is an adult while having a repelling effect on the target animal to be repelled. It becomes possible. Therefore, the beast repellent structure 1 can be easily approached to the fields and forests around which the beast repellent structure 1 is installed, so that the farm work in the fields and forests where the beast repellent structure 1 is installed is not obstructed. Of course, unlike the conventional fence, there is no need to provide a door on the fence.

  FIG. 4 is a view of a state in which a plurality of beast repellent structures 1 (33 in FIG. 4) are arranged around the field 5 and used as the beast repellent device 5 as viewed from above. As described above, since the beast repellent structure 1 has a trapezoidal shape, if it is bent little by little at overlapping portions, not only a plurality of beast repellent structures 1 are installed in a straight line but also the upper side of FIG. It is also possible to install a plurality of beast repellent structures 1 in a semicircular shape as shown in FIG. Also, the overall length can be adjusted by adjusting the overlap between the beast repellent structures 1.

  If the two beast repellent structures 1 are arranged at right angles by arranging the beast repellent structure 1 in the horizontal direction and the beast repellent structure 1 in the vertical direction, the beast repellent structure 1 What is necessary is just to insert the front-end | tip of the seven 2nd metal rods 22 (22a-22g) which protrude from the width side into the side surface of the length side of the beast repellent structure 1. FIG.

  In the embodiment shown in FIG. 4, the method is described as a method of surrounding the field 10 in a single layer. However, the entire or part of the field 10 may be surrounded by a plurality of layers such as double or triple. good. Furthermore, when making double, triple, etc., you may make it install the animal repellent structure 1 from which an outer shape differs in an inner side. For example, the outer enclosure has a plurality of beast repellent structures 1 of the present embodiment, and the inner enclosure is intended for small pests such as frogs and foxes, and the space of the partition 23 is rough 50 mm × rough 50 mm. At the same time, the height of the beast repellent structure is roughly 50 mm so that it is smaller than the beast repellent structure 1 and has a height 23 or smaller. Of course, it is also possible to use a method in which the barrier 23 and the height are larger than the beast repellent structure 1.

  Since the weight of one animal repellent structure 1 is the same as the weight of the grid-like plate 20 before processing, it is about 5 kg and can be easily carried by an adult. Therefore, it becomes easy when it is installed around a field or a forest where crops are planted. Further, even when the beast repellent structure 1 is moved for mowing or when it is installed again at the original position, the operation can be simplified.

  FIG. 5 shows a simple embodiment in which the same animal repellent effect as that of the animal repellent structure 1 can be obtained without bending the lattice plate 20. In FIG. 5, about 3 to 6 concrete blocks 6 having a thickness of 150 mm are placed on the ground for one of the grid plates 20, and one grid plate 20 is placed on about 3 to 6 concrete blocks 6. And about 3 to 6 concrete blocks 6 and the grid plate 20 are fixed by the wire 7.

  In this case, since the weight of the concrete block 6 is about 15 kg, the processing of the lattice plate 20 can be omitted, but the cost for purchasing a large number of concrete blocks 6 and the large number of concrete blocks 6 The labor and cost for transporting to the fields and mountain forests where the crops are planted, and the labor and labor for installing the concrete blocks 6 and the labor of the workers by moving heavy objects are increased. In addition, the movement after the installation by farming such as mowing also requires more labor than the beast repellent structure 1. However, even in this case, considering the installation of the fence, the concrete block 6 and the lattice-like plate 20 are simply placed and bound by the wire 7, so that it can be carried out with a simple operation.

(Second Embodiment)
A second embodiment will be described with reference to FIGS. FIG. 6 is a side view of the beast repellent structure 2 as viewed from the width side. After processing up to the lattice plate 20a of FIG. 2B of the first embodiment, only one side is bent at a height of about 250 mm. The shape seen from the side surface of the beast repellent structure 2 is formed in the shape of a rough right triangle having an opening on the ground 9 side and having the ground 9 as one side. Even in this shape, the second metal rod 22c is about 200 mm and the second metal rod 22f is about 50 mm, so that three divisions 23 are provided, and the repelling effect on the repelling target beast is obtained. It can be demonstrated.
Moreover, since the beast repellent structure 2 also has a shape that expands with respect to the ground 9, when connecting a plurality of beast repellent structures 2, the beast repellent structures 2 can be overlapped with each other.

  FIG. 7 shows a simple embodiment in which the same repellent effect as the beast repellent structure 2 can be obtained with two to three concrete blocks 6 and one unprocessed lattice-like plate 20. In addition, the concrete block 6 is installed so that it may become a height of 200 mm. As in the case of FIG. 5, the labor of processing the grid-like plate 20 can be saved, but the cost of the concrete block 6 and the labor of transportation and installation increase. Even in this case, considering that a fence is to be installed, the concrete block 6 and the lattice plate 20 are simply placed and bound by the wire 7, so that the operation can be performed with a simple operation.

(Third embodiment)
A third embodiment will be described with reference to FIG. FIG. 8 is a side view of the beast repellent structure 3 as viewed from the width side. After processing up to the grid-like plate 20a of FIG. 2B of the first embodiment, the second metal rod 22d near the central portion on the width side is bent around the axis so that the height of the second metal rod 22d is about 200 mm. It is formed as follows. The shape seen from the side surface of the beast repellent structure 3 is formed in an isosceles triangle shape having an opening on the ground 9 side and having the ground 9 as one side. Even in this shape, the second metal rod 22b and the second metal rod 22f are in the range of about 60 mm, the second metal rod 22c and the second metal rod 22e are in the range of about 150 mm, and four effective separators 23 are provided. Therefore, it is possible to exert a repelling effect on the repelling target beast.

  In addition, since the beast repellent structure 3 also has a shape that expands with respect to the ground 9, it is possible to overlap the beast repellent structures 3 when connecting a plurality of beast repellent structures 3.

(Fourth embodiment)
A fourth embodiment will be described with reference to FIG. FIG. 9 is a side view of the beast repellent structure 4 viewed from the width side. After processing up to the grid-like plate 20a of FIG. 2B of the first embodiment, the second metal rod 22d is formed to have a height of about 180 mm by bending it so as to bend roughly and uniformly to the width side. It is a thing. The shape seen from the side of the beast repellent structure 3 opens to the ground 9 side and is formed on the ground 9 as an arc shape. Even in this shape, the second metal rod 22b and the second metal rod 22f are about 80 mm in height, and the second metal rod 22c and the second metal rod 22e are about 170 mm in height. It will be provided, and can exhibit a repelling effect on the repelling target beast.

  Moreover, since the beast repellent structure 4 also has a shape that expands with respect to the ground 9, when connecting a plurality of beast repellent structures 4, the beast repellent structures 4 can be overlapped with each other.

  As mentioned above, although this invention has been demonstrated based on the 1st-4th embodiment, this invention is not limited to the structure of these embodiment at all. For example, it can be implemented by changing the combination of the embodiments. It can also be carried out by a method of molding the material of the animal repellent structure using a resin that has a predetermined strength and hardly deteriorates at the same time.
