Description

本考案は農作物に被害を与える恐れがある害獣に対し田畑などに侵入させないための構造体であり、害獣に構造体の怖さを学習させ、近づくことを忌避させる害獣の侵入を防ぐ構造体に関する。 The present invention is a structure for preventing pests that may damage crops from entering the fields, etc., and prevents pests from learning to fear the structure and avoiding approaching pests. Regarding the structure.

一般に、農作物を害獣の被害から守る方法として柵で囲う方法、金属柵に電流を通し撃退する方法や、害獣の接近を検知し超音波や警告音、光線を発する装置など様々な方法や装置が提案され、使用されている。 In general, as a method of protecting agricultural crops from damage by harmful animals, there are various methods such as a method of enclosing with a fence, a method of passing a current through a metal fence and repelling, a device that detects the approach of a harmful animal and emits an ultrasonic wave, a warning sound, a ray of light. A device has been proposed and is in use.

しかし、柵の場合、設置する面積や場所などでは広域となり、大規模な工事や設置費用が掛かるのが難点である。また害獣を検知し、音や光などで撃退する装置は大がかりとなり小規模な田畑などでは採用できないものである。 However, in the case of a fence, the area and place where it is installed is wide, and it is a difficult point that large-scale construction and installation costs are required. In addition, a device that detects a pest and repels it with sound or light is too large to be adopted in small fields such as fields.

そこで、侵入した害獣が一度、いやな目や怖い思いを経験させることで侵入を忌避させる装置や構造体が提案されている。特許文献１には害獣の肢の先端の大きさより余裕のある格子状の区切りを設けた板を、害獣の肢の長さを基準とした高さにした忌避構造体が示される。この格子状の構造体に害獣が肢を入れた時の絡まりが恐怖を与え、近寄らないようにする忌避効果を狙ったものである。また、特許文献２には同様に害獣侵入防止領域に敷設するスロープとハニカム状の開口をもつ侵入防止部を形成したもので、侵入した害獣は開口部に肢が入り込むことで恐怖を与えて移動の障害を学習させ、侵入防止部を渡ることに警戒感を与え侵入を忌避させるものである。さらに、特許文献３の害獣の侵入防止具では野生動物が侵入した時に軽度の傷を負わせることで危険ゾーンであることを教え、侵入を忌避させる防止具が提案されている。 Therefore, there has been proposed a device or structure in which an invading pest once avoids the invasion by causing it to experience unpleasant eyes and scary thoughts. Patent Document 1 discloses a repellent structure in which a plate provided with a grid-like partition having a margin larger than the size of the tip of a pest of a pest has a height based on the length of the pest of a pest. It aims at the evasion effect that the entanglement when a pest puts its limb in this lattice-shaped structure gives fear and keeps away. In addition, in Patent Document 2, an intrusion prevention part having a slope and a honeycomb-shaped opening that is similarly laid in a pest intrusion prevention area is formed, and the invading pest causes fear when the limb enters the opening. It learns the obstacles of movement and gives caution to crossing the intrusion prevention part to avoid invasion. Further, in the invasion preventive device for pests disclosed in Patent Document 3, a preventive device for avoiding invasion by teaching that it is in a dangerous zone by injuring a wild animal when it invades is proposed.

本考案によれば、害獣に危険を察知したとき逃げづらいことを学習させることで、一度危険を経験すれば侵入を忌避するようになる。使用に際しては電気も消耗剤も使用しないので設置後の維持管理が容易である。あくまで動物としての害獣に危害を加える物ではなく、人間の生活域との棲み分けができるようにすることを目的とする。 According to the present invention, by letting a pest learn that it is difficult to escape when a danger is detected, once the danger is experienced, invasion is avoided. Since neither electricity nor consumables are used during use, maintenance after installation is easy. The purpose is not to cause harm to animal pests, but to enable them to be segregated from human living areas.

本考案の実施例である害獣の侵入を防ぐ忌避構造体の斜視図である。1 is a perspective view of a repellent structure that is an embodiment of the present invention and that prevents invasion of harmful animals. 同構造体を構成する正三角形の網枠体の単体の正面図である。FIG. 3 is a front view of a single unit of a regular triangular mesh frame body that constitutes the same structure. 同構造体を組み立てる前の網枠体を展開した状態を示す説明図である。It is explanatory drawing which shows the state which expanded the net frame body before assembling the same structure.

以下、本考案を図示する実施形態により具体的に説明する。
図１は正三角形の網枠体１を４枚、夫々の辺で繋ぎ合わせて三角錐に組み立てた忌避構造体１０を示す。網枠体１は図２に示すように、三辺ａ、ｂ、ｃを芯棒１ａ、１ｂ、１ｃにより枠取りした正三角形をなし、これら三辺の芯棒に接続する鋼材１１を格子状に配して溶接などで一体に形成されている。格子状の網目の大きさは相手とする害獣の肢が容易に入り、抜くときに肢が引っかかる程度であって、害獣が網目から逃げる時、肢に負担がかかる大きさとする。網枠体１は相手とする害獣にもよるが、番線や鋼線などの鋼材１１を格子状に張り巡らせ、夫々の交差点を溶着などして形成される。この網枠体１の一辺を６０ｃｍから２００ｃｍを目安とし、組み立てた三角錐の忌避構造体１０は害獣の侵入路に点在させたり、複数個を連ねたりして設置する。 Hereinafter, the present invention will be described in detail with reference to illustrated embodiments.
FIG. 1 shows a repellent structure 10 in which four regular triangular mesh frames 1 are joined together at their respective sides to be assembled into a triangular pyramid. As shown in FIG. 2, the net frame body 1 has an equilateral triangle in which three sides a, b, and c are framed by core rods 1a, 1b, and 1c, and a steel material 11 connected to the core rods on these three sides is formed into a lattice shape. It is arranged in a single piece by welding or the like. The size of the grid-like mesh is such that the limbs of the opponent pest easily enter, and the limbs are caught when the pest is withdrawn, and when the pest escapes from the mesh, the limbs are overloaded. The net frame 1 is formed by arranging steel materials 11 such as a guard wire and a steel wire in a grid pattern, and welding each intersection, depending on the other harmful animal. As a rule, one side of the net frame body 1 is 60 cm to 200 cm, and the assembled triangular pyramid repellent structures 10 are installed in the path of invasion of a harmful beast or by connecting a plurality of them.

忌避構造体１０は、基準面となる網枠体１の三辺の芯棒１ａ、１ｂ、１ｃに同形状に形成した枠網体２、３、４を、その芯棒同士を対向させ、締着具１２で連結して一体に組み立てたものである。２ａ、２ｂ、２ｃは網枠体２の芯棒、３ａ、３ｂ、３ｃは網枠体３の芯棒、４ａ、４ｂ、４ｃは網枠体４の芯棒である。締着具は金属製の鉤状部材であればよく、特に限定はしない。 In the repellent structure 10, the frame nets 2, 3 and 4 formed in the same shape as the core rods 1a, 1b and 1c on the three sides of the net frame body 1 serving as the reference surface are tightened by making the core rods face each other. It is connected by a garment 12 and integrally assembled. Reference numerals 2a, 2b and 2c are core rods of the mesh frame body 2, 3a, 3b and 3c are core rods of the mesh frame body 3, and 4a, 4b and 4c are core rods of the mesh frame body 4. The fastener is not particularly limited as long as it is a metal hook-shaped member.

網枠体１の網目は製造上の容易さから格子状にしているが、害獣の肢に絡む形状であればよく、網目の形状には拘束されない。また、網目を構成する鋼材の太さも対象とする害獣により一様ではなく、太さに拘束されない。 The mesh of the net frame 1 is formed in a lattice shape for ease of manufacturing, but may be any shape as long as it is entwined with the limbs of the harmful animal and is not restricted by the mesh shape. Further, the thickness of the steel material forming the mesh is not uniform depending on the target pest, and is not restricted by the thickness.

次に本考案の作用を説明する。
本考案の忌避構造体１０は、同一形状の正三角形の網枠体１を４枚で１個の忌避構造体を形成する。基準面となる網枠体１の三辺の芯棒に夫々取り付けられる網枠体２、３、４をそれぞれの芯棒同士を締着具１２で連結すれば図１のように正三角錐の忌避構造体１０が出来上がる。従って、正三角形の網枠体１を必要枚数持ち込み、現場で簡単に組み立てることができる。この忌避構造体１０は害獣の出没が想定される場所に、単体の構造体を置いたり、複数個を連結し柵状に並べて設置する。設置する場所の地形や立地状況に応じて現場で任意に選択することができる。 Next, the operation of the present invention will be described.
In the repellent structure 10 of the present invention, one repellent structure is formed by four regular triangular net frame bodies 1 having the same shape. If the mesh rods 2, 3 and 4 attached to the core rods on the three sides of the mesh frame body 1 serving as the reference plane are connected by the fasteners 12, the regular triangular pyramid is repelled as shown in FIG. The structure 10 is completed. Therefore, it is possible to bring in a required number of mesh frames 1 having an equilateral triangle and easily assemble them on site. The repellent structure 10 is provided by placing a single structure or connecting a plurality of them in a fence-like arrangement at a place where a harmful animal is expected to appear. It can be arbitrarily selected at the site according to the topography of the place where it is installed and the location conditions.

本考案の忌避構造体は正三角形の三角錐形状であるため、害獣が網枠体に肢を引っ掛けて転倒させても同じ網枠体の面を呈しており、安定して忌避効果を維持することができる。本考案の忌避構造体に害獣が肢を入れた時の網枠体との絡まりが恐怖を与え、逃げづらさを学習させることで構造体に近寄らないようにする忌避効果を発揮することができる。しかも、害獣が踏み付けても三角錐の構造体は外力に強く壊されにくい。害獣が衝突しても三角錐の構造体は転がりにくく、安定して設置することができる。 Since the repellent structure of the present invention has an equilateral triangular pyramid shape, even if an injurious animal hooks its limb on the net frame and falls it, it presents the same surface of the net frame, maintaining a stable repellent effect. can do. The entanglement with the net frame when a pest puts a limb into the repellent structure of the present invention causes fear, and by learning how difficult it is to escape, it is possible to exert a repellent effect to prevent it from approaching the structure. it can. Moreover, the structure of the triangular pyramid is strong against external force and is unlikely to be destroyed even if a harmful beast steps on it. Even if a pest strikes, the triangular pyramid structure does not roll easily and can be installed stably.
