Abstract

PROBLEM TO BE SOLVED: To provide an animal trapping cage capable of efficiently trapping a relatively-large wild animal.SOLUTION: An animal trapping cage is provided with: a rotating shaft 8 that is horizontally arranged on a bottom side of a cage body 1 and is supported rotatably; a bottom plate 9 that is attached to the rotating shaft 8 so as to form part of a bottom of the cage body 1; a rectangular frame 7 that woks as a stationary part facing a rotating tip of the bottom plate 9 when the bottom plate 9 faces a horizontal direction; and a support pin 10 that is laid between the rectangular frame 7 and the bottom plate 9 and horizontally supports the bottom plate 9. When an animal rides on the bottom plate 9 and then a moment equal to or more than a prescribed value is applied to the bottom plate 9, the support pin 10 is folded, the bottom plate 9 rotates, a release string 18 passing through a lower part of the bottom plate is pulled down and thereby fall doors 2 fall, and then apertures 1a on front and rear surfaces of the cage body 1 are closed. This animal trapping cage can efficiently trap a relatively-large animal because of no threats of working in response to a small animal not to be trapped.

Description

  The present invention relates to an animal capture cage for capturing relatively large wild animals.

  As an animal trap for capturing wild animals, a trap body with openings formed on the front and rear surfaces, a pair of drop doors that close the opening by dropping from above each opening of the trap body, and each drop A door holding mechanism that holds the door above the opening of the cocoon body and a release mechanism for releasing the holding state of the falling door by the holding mechanism are often used. There are various ways to activate the release mechanism when it enters.

  For example, in the animal trapping cage proposed in Patent Document 1, the bottom plate of the cage main body is rotatably supported, and when the animal rides on the bottom plate, the bottom plate rotates to thereby release the release mechanism. The holding state of each drop door by the holding mechanism is released and each drop door is dropped.

Japanese Patent Application Laid-Open No. 8-56549

  By the way, in the animal trapping cage described in Patent Document 1, the lifting member of the release mechanism is elastically supported by the cage main body through a biasing portion so as to be movable up and down, and this lifting member is attached to the rotating front end portion of the bottom plate. The bottom plate is supported by connecting. For this reason, even if a small animal that is not the original capture target gets on the bottom plate, the bottom plate rotates to some extent due to the elasticity of the urging portion, the release mechanism operates, the falling door falls, and the front and rear surface openings of the cocoon body May be closed. Once the opening of the cage body is closed, it is necessary to lift the drop door and reset the holding mechanism to make it possible to capture the animal again. In addition, the original capture target animal cannot be captured until the holding mechanism is reset. That is, in this animal trap, when only a relatively large wild animal is to be captured, there is a problem that the capture target animal cannot be efficiently captured.

  Therefore, an object of the present invention is to provide an animal trap that can efficiently capture relatively large wild animals.

  In order to solve the above-described problems, the present invention provides a pair of drops that closes the opening by dropping from above the openings of the cocoon body, and an eagle body in which an opening into which an animal can enter is formed on the front and rear surfaces. In the animal trapping cage comprising a door, a holding mechanism for holding each of the drop doors above the opening of the rod body, and a release mechanism for releasing the holding state of the drop door by the holding mechanism, A pivot shaft that is horizontally disposed on the bottom side of the casing and is rotatably supported, a bottom plate that is attached to the pivot shaft so as to form at least a part of a bottom portion of the main body, and the bottom plate is in a horizontal direction. A fixed portion that faces the rotating tip of the bottom plate when facing the surface, and a support pin that is interposed between the fixed portion and the bottom plate to horizontally support the bottom plate, and an animal rides on the bottom plate When a moment greater than the specified value is applied to When the support pin is bent and the bottom plate is rotated integrally with the rotation shaft, the release mechanism is operated to release the holding state of each drop door by the holding mechanism, and each drop door is dropped. Each opening was closed. Here, the term “horizontal” means that the animal capture cage of the present invention is substantially horizontal as long as the above-described problems can be solved (the same applies hereinafter).

  According to said structure, even if the animal which entered the cage | basket body rides on a baseplate, if the moment which arises in a baseplate by the weight is less than predetermined value, the support pin passed between the fixing | fixed part and the baseplate Since it continues to support the bottom plate without being bent and the openings on the front and rear surfaces of the rod main body are not closed, only relatively large (heavy) animals can be captured efficiently.

  As a specific configuration, the holding mechanism is pivotally attached to the bag main body, and is locked to the bag main body and a pair of door support members that support the drop doors in a predetermined posture. And one end of which is connected to one of the door support members, and a locking portion provided at the other end is provided with a pair of connecting strings connected to the locking tool, In the release mechanism, a release piece for releasing the locking state of the locking tool to the heel body, one end is fixed to the heel body or the fixing portion, and the other end is connected to the release piece, A thing provided with the release string stretched so that it may pass under the bottom plate is adopted, and when the animal rides on the bottom plate and the bottom plate rotates, the bottom plate pushes down the release string and pulls the release piece. By this, the locking state of the locking tool to the heel body is released, and each connection from the locking tool Wherein a predetermined position of each door support member collapses unplugged, the may each fall door so as to fall at the same time.

  As described above, when the animal is placed on the bottom plate and a moment of a predetermined value or more is applied to the bottom plate, the support pin for supporting the bottom plate is bent and the bottom plate rotates as described above. Since the opening on the front and rear surfaces of the cocoon body is closed, even if a small light animal rides on the bottom plate, it maintains a state where it can be captured without closing the opening, and only relatively large animals can be captured. It can be captured efficiently.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. This animal-capturing cage is intended for capturing relatively large (heavy) animals such as cages, and as shown in FIGS. 1 and 2, an opening through which the animal to be captured can enter the front and rear surfaces. A casket body 1 in which 1a is formed, a pair of drop doors 2 and 2 that close the opening 1a by dropping from above each opening 1a of the casket body 1, and each drop door 2 above the opening 1a of the casket body 1 And a release mechanism 4 for releasing the holding state of the drop door 2 by the holding mechanism 3, and a bottom plate unit 5 set on the bottom side of the bag main body 1. Then, the bottom plate unit 5 is set in the recess C provided on the ground G, and the bag body 1 is placed on the surrounding ground G.

  The saddle body 1 is formed by arranging a steel frame material on each side of a rectangular parallelepiped, and arranging steel bars in a lattice shape on both side surfaces, an upper surface and a bottom surface, and welding these members to each other. As shown in FIGS. 2 and 3, a substantially rectangular opening 1b is formed at the center in the longitudinal direction of the bottom, and the opening 1b faces the bottom plate unit 5 when used. A reinforcing plate 6 extending in the width direction of the bag main body 1 is provided before and after the opening 1b at the bottom.

  As shown in FIGS. 2 to 4, the bottom plate unit 5 includes a rectangular frame 7 as a fixed portion formed in an outer shape slightly smaller than the opening 1 b at the bottom of the bag body 1, and a central portion in the rectangular frame 7. A pair of pivot shafts 8, 8 that are horizontally arranged in the longitudinal direction of the rod body 1 and are supported by the rectangular frame 7 so as to be pivotable at both ends, and a pair attached to each pivot shaft 8. It consists of rectangular bottom plates 9, 9 and support pins 10 that are inserted between the rectangular frame 7 and each bottom plate 9 to support each bottom plate 9 horizontally. In this embodiment, each bottom plate 9 is supported by two support pins 10, but one support pin 10 may be provided for each bottom plate 9.

  Here, each bottom plate 9 is arranged so as to form half the longitudinal center portion of the bottom portion of the heel body 1, and the lower surface of the end portion on the center side in the width direction of the heel body 1 is fixed to the rotation shaft 8. When turned in the horizontal direction, the tip of the rotation faces the inner wall of the short side of the rectangular frame 7. Further, as shown in FIG. 4A, a band-like portion 9a that rises upward is formed on the upper surface of the rotating tip of each bottom plate 9, and this belt-like portion 9a and the short side of the rectangular frame 7 facing this band-like portion 9a. Each of the bottom plates 9 is supported horizontally by inserting the support pins 10 so as to penetrate the upper end portion of the bottom plate 9. Each support pin 10 is made of a soft metal such as aluminum. As shown in FIG. 4B, when a moment of a predetermined value or more is applied to the bottom plate 9, the support pin 10 bends and the bottom plate 9 is separated from the support pin 10 and rotates together with the rotation shaft 7.

  As shown in FIGS. 1 and 2, each of the drop doors 2 has a steel frame material arranged on each side of a quadrangle, and steel rods arranged in a lattice shape on the inside thereof, and these members are welded to each other. Thus, it can be raised and lowered by being guided by guide members (not shown) standing on both sides of the opening 1a of the bag main body 1. Further, an inverted U-shaped lifting member 11 is attached upward to the steel frame material forming the lower side of the quadrangle, and the lifting member 11 is used to hold the drop door 2 by the holding mechanism 3 as will be described later. Used.

  The holding mechanism 3 is engaged with a pair of support rods (door support members) 12 and 12 that are rotatably attached to both ends in the longitudinal direction of the upper surface of the basket body 1 and a longitudinal central portion of the upper surface of the basket body 1. The locking tool 13 (refer FIG. 5) to be stopped is provided, and a pair of connecting cords 14 and 14 that connect each support rod 12 and the locking tool 13 are provided. In the set state in which animals can be captured, each support bar 12 is in a posture in which the lifting member 11 of the drop door 2 is hooked at one end and the other end is inclined slightly higher so that the drop door 2 is attached to the main body 1. It is held above the opening 1a.

  Here, as shown in FIG. 5 (a), the locking tool 13 is an L-shaped bar member, and in the set state (locked state), the long portion 13a on one end side is directed horizontally. Each connecting string 14 is connected to the short part 13b in a posture in which the short part 13b on the end side faces downward. At this time, one end of each connecting string 14 is coupled to the support rod 12, and an annular locking portion 14 a provided at the other end is hung on the short portion 13 b of the locking tool 13, so that the locking tool 13 is The main body 1 is stretched while being pulled to one side in the width direction. Further, a connecting ring 16 attached at one end to the other end of the locking cord 15 coupled to the bag main body 1 is hung on the short portion 13b of the locking device 13, and the locking cord 15 connects the locking device 13 to each other. It is stretched in a state of being pulled to the side opposite to the connecting string 14. Then, the locking string 15 is passed through a release ring (release piece) 17 hung on the long portion 13a of the locking tool 13 in the middle, and the angle for pulling the locking tool 13 is adjusted. As a result, the force with which each of the connecting strings 14 and the locking string 15 pulls the locking tool 13 is balanced, so that each support bar 12 can hold the drop door 2 in the posture shown by the solid line in FIG.

  The release mechanism 4 includes a release ring 17 (see FIG. 5A) that is hung on the long portion 13a of the locking tool 13 in the set state as described above, one end fixed to the rectangular frame 7, and the like. A release string 18 (see FIGS. 2 and 5A) whose end is coupled to the release ring 17 is provided.

  Here, as shown in FIGS. 2, 3, and 4 (a), the release string 18 passes from the inner wall on one side of the rectangular frame 7 below the pair of bottom plates 9, 9 to the other of the rectangular frame 7. After penetrating the side wall, it extends from the bottom of the heel body 1 to the outside, rises along the other side surface, and is stretched so as to be coupled to the release ring 17 above the upper surface of the heel body 1. In this embodiment, one end of the release string 18 is fixed to the rectangular frame 7, but it may be fixed to the bag main body 1.

  As shown in FIGS. 2 and 4 (b), when a downward moment of a predetermined value or more is applied to the bottom plate 9, the support pin 10 bends and comes out of the bottom plate 9, and the bottom plate 9 is integrated with the rotating shaft 8. The release string 18 that rotates and passes below is rotated. At the same time, the release ring 17 is pulled out of the elongated portion 13a of the locking tool 13 as shown by a one-dot chain line in FIG. Then, the balance of the force with which each connecting string 14 and the locking string 15 pulls the locking tool 13 is lost, and the locking state of the locking tool 13 to the heel body 1 is released. As a result, as shown in FIG. 5 (b), the locking portions 14a and the connecting rings 16 of the connecting cords 14 are detached from the short portions 13b of the locking tools 13, and the supporting rods are shown as shown by a one-dot chain line in FIG. 12 is greatly rotated by the weight of the drop door 2, and the drop doors 2 are dropped simultaneously.

  As described above, this animal catching cage is inserted between the rectangular frame 7 and the bottom plate 9 of the bottom plate unit 5 when an animal rides on the bottom plate 9 and a moment of a predetermined value or more is applied to the bottom plate 9. When the support pin 10 is bent and the bottom plate 9 is rotated, the release mechanism 4 is actuated to release the holding state of the drop doors 2 by the holding mechanism 3, and the drop doors 2 are dropped at the same time so The opening 1a on the front and rear surfaces of 1 is closed.

  Therefore, even if a small animal that is not to be captured enters the cage body 1 and rides on the bottom plate 9, if the moment generated on the bottom plate 9 by the weight of the animal is less than a predetermined value, the support pin 10 is not bent and the bottom plate 9 is not bent. Since it keeps supporting, each opening 1a of the bag main body 1 is not closed, but the state which can be captured is maintained. For this reason, the holding mechanism 3 and the release mechanism 4 are reset less frequently than the conventional one that may operate even for small animals that are not captured, and each opening 1a of the cocoon body 1 is closed. Since the period of time is shortened, it is possible to efficiently capture a relatively large animal to be captured.
