Description

【０００１】
【発明の属する技術分野】
この発明は猪・鹿・熊・猿・狐・鴉も捕獲できる有害鳥獣駆除の捕獲檻である。
【０００２】
【従来の技術】
捕獲用檻として、左右の各端部に開口を有し、地上に設置される角筒形の檻本体と上記檻本体の左右の開口上に垂直に立って支持され、垂直に降下して左右の開口を同時に塞ぐ左右一対のシャッターを備えたものは、従来から公知である。これら従来の捕獲用檻の多くは左右の開口から檻の中に踏み込んだ動物の重量で檻の底板が下向きに動いたり、内部中央回転自在な回転腕と連動して前後の開口の上で垂直に立っているシャッターの降下を阻止していたストッパーが外れ、シャッターが降下して左右の開口を同時に塞ぎ、檻本体の内部に動物を捕獲する。
【０００３】
【発明が解決しようとする課題】
従って、捕獲できるの檻の底板を下向きに動かすことができる重量を有する猪・熊などの大形の獣であり、軽量な猿や鴉などの鳥は捕獲できない。又、底板は下向きに動けるように地面から上にバネなどで浮かせおく必要があるので、獣道などに仕掛けても動物が警戒し、檻の中に仲々入らない。又、バネなどで浮かされた底板を地面と同じ平面にするには、仕掛ける際に地面を掘り下げ、掘り下げた内部に設置しなければならないので動物が警戒すると供に、地面を掘り下げるのに手数がかかる。又、中央内部で回転する旋回腕は、動物が入ると破損が大きく１回１回修理や取替が必要となる。又、獣道が変わった場合大型檻は分解できず、移動は費用面で高額につき捕獲効率の悪い檻も多い。動物も学習していて一つの方法では捕獲が難しくなり、又、修理費用や数種類の檻を購入すると費用的に高くつく。
【０００４】
【課題を解決するための手段】
本発明は、上述した問題点を解決するために開発されたもので左右の各端部に開口を有し、地上に設置される角筒形の檻本体の上記檻本体の左右の開口の上に垂直に立って支持され垂直に降下した左右の開口を同時に塞ぐ左右一対のシャッター１８，１８を備えた捕獲檻に、檻本体側面に位置する可動アーム２７檻本体内に入った動物により動かされる仕掛け１６・２８・２９・３０は檻本体上面部のストッパー機構２０の中央部の図８に示すバランスアーム１３，１３は連結棒１４とネジ付シャフト１２にボルトとダブルナットで可動するよう支持され連結棒ガイド２６と前後フレ止め１９は天井枠３上部に溶接などで固定されているために、前後方向に曲がる、力の方向と強さがタンパックル１１で調整出来る。捕獲しようとする動物の種類や習性の違いにより取替られる数種類の仕掛け１６・２８・２９・３０はスプリング等を使用せず、１台の檻で取替使用できる特徴を備えた強力な捕獲檻としては安価である。
【０００５】
【発明の実施の形態】
図示の実施形態において１は左右に開口を有する角筒形の檻本体は側面枠４、天井枠３、底面枠５、シャッター１８，１８とからなる上記各金網は太い金属材、例えば天井、底面の外枠はフラットバーに６φｍｍ金網１００ｃｍ×２００ｃｍの金網を溶接などで固定し、側面枠４，４はアングル材に６φｍｍφ網１００ｃｍ×２００ｃｍを溶接、中央部はフラットバーで格子となり重量は約１４０ｋｇ位ですが移動の時は分解出来るよう外枠のフラットバー、アングルにネジを切ってナットを使用せずＭ８のボルト止メにして現地組立が好ましい。
【０００６】
檻本体の左右の開口上部、つまり側面枠４の各両端部にシャッター１８，１８が垂直に降下して開口を閉じるのを相対向してガイドするガイド部材（アングル材）２，２を設けておく。又、この各ガイド部材２，２の上には各開口の上で垂直に立つ左右のシャッター１８，１８を垂直に降下可能に支持する上部ガイド部材２１，２１を延長上に設ける。
【０００７】
左右のシャッター１８，１８も太いアングル材からなる外枠レール６外枠の内部に溶接された金網と格子材とで構成する。その寸法は前述の檻本体の場合１００ｃｍ×幅約１００ｃｍであり、このシャッター１８，１８を垂直に動くのを支持するガイド部材２と２１は二重のアングル材で上下方向は１４５ｃｍあれば良い。シャッター１８，１８には図１１に示す可動フック９を付け、シャッター１８，１８を速く降下さす。又、降下したシャッター１８，１８が開き動物が逃げないよう図１２に示す閉鎖自動ロック７上部に位置し、図１３に示す作業の安全性を考慮して丸棒を内側に傾斜し、自重で抜けない安全開口ロック８を付け、シャッター１８，１８も山などに移動する場合は取り外せるようにしておく。
【０００８】
檻本体の側面枠４に回転軸受上用２５と回転軸受下用２４が着脱可能な回転シャフト１５と仕掛け１６が可動するよう支持し、天井枠３上部に位置するストッパー機構２０は図３に示す。バランスアーム１３，１３に連なる連結棒１４はシャッター１８，１８の自重で外側に押出す力が作用し回転シャフト１５に固定してある回転シャフトロック２３が止めたり、又、回転すると係止め状態を解除する図９に示す。側面枠４上部中央に位置する回転軸受上２５と回転軸受下２４、回転シャフト１５と連結し、捕獲する動物によって蝶ネジロック用２２を回して高さを調整着脱出来る仕掛け１６を動物が回動さすことにより図３檻本体天井枠３上部のストッパー機構２０の左右両端部にストッパー腕１０に垂直に立っている一対のシャッター１８，１８の安全ロック８を解除して有ると垂直に降下しシャッター１８，１８が閉じた後は、回転シャフト１５が側面に位置するため動物が押し倒したりしないので、破損が少ない。回転形は捕獲しようとする動物の大きさにより仕掛け１６の高さを調整し、猪・鹿・熊に使用する捕獲檻。
【０００９】
檻本体に仕掛け２８を使用するには側面枠４に可動アーム止メ１７を位置し可動アーム２７の上端を連結棒１４に連結し一端部を側面枠４につけた仕掛け２８を係止めの状態に位置して図１と図４に示す檻本体は動物の習性等を考え獣道に設置して檻本体内の底面手前の左回り方向から中央部に多く動物の好物のエサを置き、エサの上で低い位置にサンドイッチ状態にして仕掛け２８（木・竹）の下には好物のイモや樹脂、ミミズ等を置き、係止め状態にし檻本体内に入ってきた猪が鼻や足で食べ物を動かす習性で仕掛けの一端部を係止めを解除すると檻本体上部のストッパー機構２０の両端に位置するストッパー腕の１０，１０から可動フック９が離脱して左右一対のシャッター１８，１８が同時に降下し開口を塞ぐ、機構は大小問わず猪専用の捕獲檻。
【００１０】
檻本体仕掛け２９・３０の使用は図２に示すストッパー機構２０のバランスアーム１３，１３からシャッター１８，１８の自重で前後に可動し力の方向を変え、連結棒１４からワイヤー２９に力を伝えるバランスアーム１３，１３の中央側の内角度が１８０度から９０度以下に可動するが１７０度では仕掛け３０を引く力が弱く細い釣り糸も使用可能なので小動物や鴉等には細くて見えにくいので適している。又、降下も遅くなる。９０度に近くなると仕掛け２９を引く力が強くなりシャッター１８，１８は速く降下する。鹿・猪・熊の親でないと可動しない。檻内には好奇心の強い子供から入るがシャッター１８，１８は可動しないので安全と思い親が入る。被害を多くする大型害獣の捕獲用も動物を絶滅させないために必要。又、図４に示すバランスアーム１３，１３を直線的に位置し、連結棒１４を細いワイヤー２９に連結し一方を側面枠４に固定し仕掛け２９の中間部を左右に押すとストッパー機構２０が可動し、開口上部左右一対のシャッター１８，１８を降下さす。又、引く運動をする動物には一方を魚釣りのように仕掛け３０の糸や針金に好物のエサを取付けエサを持ち帰る習性のある猿や狐などに適している。又、連結棒１４の単純な前後運動でシャッター１８，１８は上部で支持したり降下したりするので前後運動する電磁式の遠隔操作装置器具は取付けしやすい。
【００１１】
檻本体の左右各開口の上部にシャッター１８，１８が垂直に立ち、停まった状態は図４に示す。ストッパー気機構２０は前後フレ止メ１９とストッパー受３１により支持され可動する。図１１に示すストッパー腕１０，１０の上端部は可動フック９の接する上面を水平に保つようタンパックル１１で調整し、ネジ付シャフトに連結され前後フレ止メ１９で前後の移動を止め左右の可動をガイドする天井枠中央部左右一直線状態からへの字形に可動するようにボルトとダブルナットで位置されたバランスアーム１３，１３は連結棒１４にて前後方向に力が可動しガイドする連結棒ガイド２６に有る蝶ネジ２２を締めるとストッパー機構２０とストッパー腕１０が図４の一直線の状態で安全ロック状態となり、両端部のストッパー腕１０の上にシャッター１８，１８を垂直に立った状態で降下を停める。
【００１２】
【発明の効果】
以上で明らかなように本発明は檻本体に入った動物の重量で床面枠が下に動く必要がない。従って檻本体を地面に設置すると底面枠が地面と同一面になり、又、中央部に押し回す障害物が少ないので動物が警戒しないで開口から入る。又、入った後檻本体中央部を動物によって破損されることも少なく、設置する時地面を平らにするだけで地面を掘り下げることもない。捕獲する動物の大きさ、種類によって仕掛け１６・２８・２９・３０を取替可能で檻本体の購入台数を少なくして、効率よく有害鳥獣被害の多い場所に分解移動組立出来る手段を設けたことを特徴とし、安全開口ロック等を付けて作業の安全性を考えた捕獲檻。

BACKGROUND OF THE INVENTION
This invention is a trap for the control of harmful birds and beasts that can also capture traps, deer, bears, monkeys, traps and traps.
[0002]
[Prior art]
As capture traps, there is an opening at each end of the left and right, and is supported by standing upright on the square tube trap set installed on the ground and the left and right openings of the trap set. A device having a pair of left and right shutters that simultaneously close the openings is known. Many of these conventional traps use the weight of the animal that has stepped into the cage from the left and right openings, and the bottom plate of the cage moves downward, or in conjunction with the rotating arms that can rotate inside the center, vertically on the front and rear openings. The stopper that prevented the standing shutter from descending is removed, the shutter descends and simultaneously closes the left and right openings, and the animal is captured inside the cage body.
[0003]
[Problems to be solved by the invention]
Therefore, it is a large beast such as a spider / bear that has a weight that can move the bottom plate of the spider that can be captured downward, and cannot capture light monkeys, spiders and other birds. Also, since the bottom plate needs to be lifted from the ground with a spring so that it can move downward, the animal is wary even if it is placed on the beast path, etc., and does not get caught in the cage. In addition, in order to make the bottom plate floated by a spring etc. the same plane as the ground, it is necessary to dig up the ground when setting it up and install it inside the dug down, so it takes time to dig up the ground as well as the animal is wary . In addition, the swivel arm that rotates inside the center is severely damaged when an animal enters, and requires repair or replacement once. In addition, when the beast path changes, the large cage cannot be disassembled, and there are many cages with poor capture efficiency due to the high cost of movement. The animals are also learned, making it difficult to capture with one method, and the cost of repairs and purchasing several types of spiders can be expensive.
[0004]
[Means for Solving the Problems]
The present invention was developed to solve the above-described problems, and has an opening at each of the left and right ends, and above the left and right openings of the above-described rod body of the rectangular tube-shaped rod body installed on the ground. A movable arm 27 located on the side surface of the cocoon body is moved by an animal contained in the cocoon body to a capture cage equipped with a pair of left and right shutters 18, 18 that simultaneously support the vertically opened left and right openings. The devices 16, 28, 29, and 30 are supported by the connecting rod 14 and the threaded shaft 12 so that the balance arms 13 and 13 can be moved by bolts and double nuts in the central portion of the stopper mechanism 20 on the upper surface of the bag body. Since the connecting rod guide 26 and the front / rear anti-fretting 19 are fixed to the upper part of the ceiling frame 3 by welding or the like, the direction and strength of the force that bends in the front / rear direction can be adjusted by the tampackle 11. Several types of devices 16, 28, 29, and 30 that can be replaced due to differences in the types of animals to be captured and their habits do not use springs, etc. It is inexpensive.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
In the illustrated embodiment, reference numeral 1 denotes a rectangular tube-shaped bag body having openings on the left and right sides, a side frame 4, a ceiling frame 3, a bottom frame 5, and shutters 18, 18. The outer frame is fixed to a flat bar by welding with a wire mesh of 6φmm wire mesh 100cm × 200cm, the side frames 4 and 4 are welded to the angle material 6φmmφ mesh 100cm × 200cm, the center part is a flat bar with a grid and the weight is about 140kg However, when moving, it is preferable to assemble the M8 bolts without using nuts and cutting the flat bars and angles of the outer frame so that they can be disassembled.

Further, on the guide members 2 and 2, upper guide members 21 and 21 for supporting the left and right shutters 18 and 18 standing vertically on the respective openings so as to be vertically lowered are provided on the extensions.
[0007]
The left and right shutters 18 and 18 are also composed of a wire mesh and a lattice material welded inside the outer frame rail 6 outer frame made of a thick angle material. In the case of the above-described bag body, the size is 100 cm × width is about 100 cm. The guide members 2 and 21 that support the vertical movement of the shutters 18 and 18 need only be double angle members and 145 cm in the vertical direction. The movable hooks 9 shown in FIG. 11 are attached to the shutters 18 and 18, and the shutters 18 and 18 are quickly lowered. Further, the lowered shutters 18 and 18 are opened so that the animal does not escape, and is positioned on the upper part of the automatic closing lock 7 shown in FIG. 12. In consideration of the safety of the work shown in FIG. A safety opening lock 8 that cannot be removed is attached, and the shutters 18 and 18 are also removable when moving to a mountain or the like.
[0008]
The stopper mechanism 20 positioned above the ceiling frame 3 is shown in FIG. 3 and is supported on the side frame 4 of the main body so that the rotary shaft 15 and the device 16 on which the rotary bearing upper part 25 and the rotary bearing lower part 24 can be attached and detached are movable. . The connecting rod 14 connected to the balance arms 13, 13 is pushed outward by the weight of the shutters 18, 18, and the rotating shaft lock 23 fixed to the rotating shaft 15 is stopped. The release is shown in FIG. The animal rotates the mechanism 16 that is connected to the rotary bearing upper 25, the rotary bearing lower 24, and the rotary shaft 15 that are located at the upper center of the side frame 4 and that can be adjusted and removed by turning the thumbscrew lock 22 according to the animal to be captured. Thus, when the safety lock 8 of the pair of shutters 18 and 18 standing vertically to the stopper arm 10 is released at the left and right ends of the stopper mechanism 20 at the top of the ceiling frame 3 in FIG. , 18 is closed, and the rotating shaft 15 is located on the side surface so that the animal is not pushed down, so that there is little damage. The rotary type is a trap used for traps, deers, and bears by adjusting the height of the device 16 according to the size of the animal to be captured.
[0009]
To use the device 28 on the main body, the movable arm stopper 17 is positioned on the side frame 4, the upper end of the movable arm 27 is connected to the connecting rod 14, and the device 28 having one end attached to the side frame 4 is locked. 1 and 4 are placed on the beast path considering the habits of animals, and many animal favorite foods are placed in the center from the counterclockwise direction in front of the bottom in the body.

When one end of the mechanism is unlocked by the habit of moving, the movable hook 9 is detached from the stopper arms 10 and 10 located at both ends of the stopper mechanism 20 at the upper part of the bag body, and the pair of left and right shutters 18 and 18 are simultaneously lowered. The mechanism that closes the opening is large and small Capture cage of use.
[0010]
The use of the main body devices 29 and 30 moves back and forth by the weights of the shutters 18 and 18 from the balance arms 13 and 13 of the stopper mechanism 20 shown in FIG. 2 to change the direction of the force, and transmits the force from the connecting rod 14 to the wire 29. The inner angle of the balance arms 13, 13 is movable from 180 degrees to 90 degrees or less, but at 170 degrees, the force to pull the device 30 is weak and thin fishing lines can be used, so it is suitable for small animals and rods because they are thin and difficult to see. ing. Also, the descent is slowed down. When approaching 90 degrees, the force to pull the device 29 becomes stronger, and the shutters 18 and 18 descend quickly. It cannot move unless it is a parent of a deer, a shark, and a bear. A curious child enters the cage, but since the shutters 18 and 18 do not move, it is safe and parents enter. It is also necessary to capture large pests that cause a lot of damage in order to prevent the animals from becoming extinct. Further, when the balance arms 13 and 13 shown in FIG. 4 are positioned linearly, the connecting rod 14 is connected to the thin wire 29, one side is fixed to the side frame 4, and the intermediate portion of the device 29 is pushed left and right, the stopper mechanism 20 is moved. It moves and lowers the pair of shutters 18, 18 at the upper left and right of the opening. For animals that pull, it is suitable for monkeys and frogs with habits of bringing one's favorite food by attaching one's favorite food to the thread or wire of the device 30 like fishing. Further, since the shutters 18 and 18 are supported or lowered by a simple back and forth movement of the connecting rod 14, an electromagnetic remote control device that moves back and forth is easy to install.
[0011]
FIG. 4 shows a state in which the shutters 18 and 18 stand vertically and stop at the upper portions of the left and right openings of the bag body. The stopper air mechanism 20 is supported and moved by the front and rear anti-flare 19 and the stopper receiver 31. The upper ends of the stopper arms 10 and 10 shown in FIG. 11 are adjusted by a tampackle 11 so as to keep the upper surface in contact with the movable hook 9 horizontal, and are connected to a threaded shaft to stop the front and rear movement by a front and rear fringe 19 and move left and right. The balance arm 13, 13 positioned by a bolt and a double nut so as to be movable in a shape of a left-right straight line from the center of the ceiling frame that guides the connecting rod 14 is a connecting rod guide that is guided by a connecting rod 14 that moves in the front-rear direction. When the thumbscrew 22 at 26 is tightened, the stopper mechanism 20 and the stopper arm 10 are in the safety locked state in the straight line state of FIG. 4, and the shutters 18 and 18 are vertically lowered on the stopper arms 10 at both ends. Stop.
[0012]
【The invention's effect】
As is apparent from the above, the present invention does not require the floor frame to move downward due to the weight of the animal that has entered the main body of the cage. Therefore, when the cage body is installed on the ground, the bottom frame becomes flush with the ground, and there are few obstacles to push around the center, so the animal enters from the opening without being wary. Also, after entering, the central part of the main body is rarely damaged by animals, and when installed, the ground is flattened and the ground is not dug down. The mechanism 16, 28, 29, and 30 can be replaced depending on the size and type of animals to be captured, and the number of kite bodies purchased can be reduced, providing means for efficiently disassembling, moving and assembling in a place where there is much damage to harmful birds and beasts. This is a capture trap that features safety opening locks and other features to ensure work safety.
