However, the configuration of the capture device disclosed in Patent Document 1 still has the following problems. That is, firstly, the hook-shaped bait receiving portion for hooking animal bait, and the central and side weights for closing the opening of the catching net are mechanically connected via a chain, an oscillating member, a tension coil spring, and the like. When the harmful animal pulls the bait, the central weight and the side weights drop in sequence. In addition to the fact that the weight is not constant, it is possible that the weight may not drop, and it is not easy to prepare for the next use by hoisting the weight.

Second, even if the central weight falls along the drop guide rail, it has a cylindrical shape and is installed in a scattered distribution state separate from the side weights, so the opening of the catching net Since the opening is merely rimmed and reinforced with a string-like body, it is difficult to close the left and right sides of the opening quickly and reliably, and there is a risk that the harmful animal may escape from there.

Thirdly, a plurality of anti-slippage bodies are attached at random to the outside and inside of the catching net. In addition, because it traps harmful animals inside, it can injure the animal to the point of bleeding. be.

Fourthly, the holding member (framework) of the catching net is designed to be used independently on the ground by means of a plurality of struts. As such, if the trapped pest becomes violent, the holding member will also be dragged along the ground.

The object of the present invention is to solve such problems. Suspended in a shape-retaining state,

The front of the frame is partitioned into rectangles by a horizontal movable hanger bar, a horizontal grounding bar, and a pair of left and right telescoping guide struts for net bags . is integrated with the

By controlling the operation to release the trigger based on the output signal from the intrusion detection sensor for harmful animals that has detected a harmful animal that has entered through the front opening of the net bag, the movable hanger bar automatically falls and the net is opened. Closing the front opening of the bag ,

The upper and lower gaps between the fallen movable hanger bar and the ground are blocked by the blocking bar so that noxious animals cannot escape.

In claim 2, the movable hanger bar falls along a pair of left and right fixed supports that take charge of the top bar,

It is characterized in that the net bag attached to the movable hanger bar is designed to shrink along the telescopic guide post as the movable hanger bar drops.

In claim 3, the trigger is formed from a magnetic body attached to the movable hanger bar and an electromagnet attached to the top bar to detachably attract the magnetic body,

Only when power is supplied to the electromagnet, the attraction state of the magnetic body is released, and the movable hanger bar is dropped to the closed state of the front opening of the mesh bag.

In claim 4, at least three of a pair of left and right parallel vertical beams extending along the front-rear direction of the framework constructed in a substantially rectangular parallelepiped shape and a horizontal beam extending along the left-right direction of the framework are used as the magnetic material. while

A plurality of scattered permanent magnets are attached to the upper surface of the mesh bag, which is held in a substantially rectangular parallelepiped shape by the framework, in a bordering state,

Permanent magnets on the upper surface of the net bag are attracted to the vertical and horizontal beams of the magnetic material, thereby suspending the net bag from the framework,

As the movable hanger bar drops to close the front opening of the net bag, the upper surface of the net bag drops so as to be gradually peeled off from the front side while resisting the attraction force of the permanent magnet. , characterized in that it is defined to confine the harmful animal.

A fifth aspect of the present invention is characterized in that at least four corner columns of the framework constructed in a substantially rectangular parallelepiped shape are detachably connected and fixed to piles driven into the ground.

In claim 6, the net bag is braided from net yarns of synthetic fibers with metal core wires into a substantially rectangular parallelepiped shape that is open only in the front, and is detachable from the framework.

In claim 7, a pair of grounding base plates are assembled and fixed to the left and right ends of the grounding bar, and from the grounding baseplates, the front corner struts of the framework, the fixed struts that support the top bar, and the telescopic guide struts for the net bag are integrated. along with

A pair of left and right fixed columns are formed into a pair of front and rear pairs, and the gap between the front and rear of the pair is used as a drop guide groove for the movable hanger bar so that the movable hanger bar can be dropped between the left and right sides of the drop guide grooves. It is characterized in that it is horizontally pierced in this manner.

In claim 8, the movable hanger bar protrudes from the top bar fixed support that generates the drop guide groove,

A stand integrally suspended from the ground base plate, a footrest welded to the lower end of the stand, an elevation adjustment bolt screwed to the footrest, and a movable hanger bar that has fallen from below. A stopper made of cushion rubber attached to the upper end of the lifting adjustment bolt and a rotatably attached to the upper end of the stand via a horizontal fulcrum shaft prevent the dropped movable hanger bar from rising. Correspondingly installed a pair of locking mechanisms consisting of anti-floating arms for the movable hanger bar that act as non-return valves,

It is characterized in that the floating prevention arm of the locking mechanism locks the movable hanger bar in a falling state.

According to the configuration of claim 1, the front opening of the frame for suspending the net bag for trapping harmful animals in a shape-retaining state of a substantially rectangular parallelepiped (U-shaped cross-section with only a front opening) is connected to the upper horizontal movable hanger bar. A rectangular section is formed from the lower horizontal grounding bar and a pair of left and right vertical telescopic guide struts for the net bag, and especially the front opening side edge of the net bag can be stretched and stretched to the pair of left and right telescopic guide struts. Therefore, when the movable hanger bar drops, the left and right side edges of the front opening of the net bag are contracted (folded) in a bellows shape along the telescopic guide struts. There is no room for a gap to be generated between the left and right sides of the telescopic guide post, and it is completely closed by itself.

As a result, the upper edge of the front opening and the lower edge of the front opening of the net bag are attached to the movable hanger bar and the ground bar of the framework, respectively, so that harmful animals can be captured easily and reliably. be able to.

In addition, the net bag has a simple U-shaped cross section (almost a rectangular parallelepiped), and includes a plurality of scattered weights, positional displacement prevention members, and a large number of intertwined hook metal fittings as described in Patent Document 1 at the beginning. When the horizontal movable hanger bar is dropped, the entire rectangular front opening of the mesh bag is closed at once. As a necessary configuration, it is extremely simple and sufficient, and is excellent in terms of convenience in use and efficiency in mass production.

In particular, since the lower position of the movable hanger bar is attached and integrated with a horizontal cutoff bar that serves as a weight body, harmful animals trapped in the net bag can move up and down between the fallen movable hanger bar and the ground. In addition to preventing the danger of escaping forward (front) through the mutual gap, the blocking bar can be used as a weight body for the movable hanger bar, and the hanger bar can be quickly dropped by its own weight. There is also

In addition, the above movable hanger bar is suspended from a horizontal top bar that is fixed and horizontally positioned above it via an electromagnetic trigger, and the trigger is used as a detection output signal of a noxious animal intrusion detection sensor. Since the base is released and the movable hanger bar is allowed to drop by its own weight, the plurality of weight bodies, the positional displacement prevention bodies, and the many intertwined hook metal fittings described in Patent Document 1 are completely eliminated. , the preparation work for the next use can be done quickly and simply by one person.

In that case, if the configuration of claim 2 is adopted, the pair of left and right fixed struts that are in charge of the top bar of the frame can be used together, and the movable hanger bar can be dropped smoothly and correctly along the struts. Furthermore, it helps to stabilize the contraction (folding) action of the net bag along the telescopic guide struts.

If the configuration of claim 3 is adopted, the movable hanger bar is designed to drop only when power is supplied to the electromagnet of the trigger. Since the trigger electromagnet is not powered, excellent energy-saving effect can be obtained.

If the configuration of claim 4 is adopted, as the movable hanger bar drops to close the front opening of the net bag, the upper surface (ceiling surface) of the net bag gradually moves horizontally from the front side. Since the net bag falls as if being torn off from the vertical and horizontal beams, the entire mesh bag can be smoothly closed to quickly confine the harmful animal. Moreover, the preparation work for suspending the upper surface of the net bag from the vertical and horizontal beams of the framework for re-use can be performed quickly and conveniently by one-touch operation by one person.

If the configuration of claim 5 is adopted, the risk of being dragged and moved by the riot of the captured pests in the frame of the trapping net bag can be reliably prevented by connecting and integrating with the stakes driven into the ground. It is preventable and safe.

If the configuration of claim 6 is adopted, the net bag is generally simple in that it is braided from strong net threads (cords) of synthetic fibers with metal core wires into a U-shaped cross section (almost a rectangular parallelepiped) that is open only in the front. Since it is a lightweight item in shape and can be removed from the frame, when changing the installation location, the net bag can be rolled into a roll and conveniently transported together with the disassembled structural members of the frame. be able to.

Moreover, since the net bag is not equipped with a plurality of scattered weights, a positional displacement prevention member, and a large number of intertwined hook metal fittings described in Patent Document 1 at the beginning, it is possible to unnecessarily injure a harmful animal. , there is no risk of deteriorating the quality of the meat, and the operator can safely handle the meat, eliminating the need for troublesome preparatory work for untangling the entanglements the next time the meat is used.

Furthermore, if the configuration of claim 7 is adopted, the front opening of the frame is formed by a pair of left and right ground base plates, front corner struts integrally hanging from the respective ground base plates, fixed struts for holding the top bar, and net bags. The telescoping guide struts make it possible to create a strong three-dimensional framework, which helps improve durability. In addition, the space between the front and rear fixed struts, which are lined up one by one, is used as a drop guide groove for the horizontal movable hanger bar. There is also an effect that the movable hanger bar can be dropped smoothly and correctly along the groove.

In that case, if the configuration of claim 8 is adopted, a pair of lock mechanisms provided correspondingly to the left and right ends of the horizontal movable hanger bar projecting from the fixed column locks the movable hanger bar in a falling state, It can be prevented from being pushed up by trapped pests.

It is a movable hanger bar horizontally penetrating between the front and rear fixed struts (18) for the top bar, and the space between the front and rear fixed struts (18) serves as a drop guide groove (G) so that the hanger can fall. It has become.

(23) is a horizontal cut-off bar attached and integrated to the lower position of the movable hanger bar (22) through a plurality of connecting stays (24), for quickly dropping the movable hanger bar (22) itself. In addition to functioning as a weight body, by narrowly shutting off the vertical mutual gap between the dropped movable hanger bar (22) and the ground (GL), harmful animals caught in the net bag (N) It is also possible to prevent the possibility of escaping forward from the mutual gap.

The top bar (17) mentioned above is made of a metal square bar (shaped steel) or the like, and a pair of mounting plates (25) attached and integrated to the left and right ends of the top bar (17) are, as is clear from FIGS. 1 and 5, It is joined to the top plate (21) corresponding to the upper end of the top bar fixing support (18), and is detachably connected and fixed via a screw fastener (26).

Flange bushings (27) projecting forward and integrally from the vicinity of both left and right ends of the horizontal top bar (17) support the upper ends of the mesh bag expandable guide struts (19). The upper end of the telescopic guide post (19) is inserted removably into the bushing (27) on the side of the top bar (17) and suspended. (28) is a retaining bolt that presses the upper end of the telescopic guide post (19).

As is clear from the front view of FIG. 1, the front of the frame (F) constructed in the rectangular parallelepiped is a horizontal movable hanger bar (22), a horizontal grounding bar (15) and a pair of left and right telescopic guides for net bags. A rectangular section is formed by the struts (19).

The upper surface (ceiling surface) of the net bag (N) having a U-shaped cross section (almost a rectangular parallelepiped) is connected to at least three magnetic longitudinal beams (11) and horizontal beams (12) of the framework (F). , are suspended as shown in FIGS.

Moreover, the upper edge of the front opening of the net bag (N) is attached to the movable hanger bar (22) by a number of binding bands (29), and the lower edge of the front opening of the net bag (N) is also attached to the ground bar ( 15) is attached to the front side of 15) by a large number of binding bands (30), etc., and the edge of the front opening side of the net bag (N) is connected to a pair of right and left telescopic guide struts (19) for the net bag. , and it is woven so that it can stretch along this.

On the other hand, the upper edge of the front opening of the net bag (N) is removed from the movable hanger bar (22), the lower edge of the front opening is similarly removed from the ground bar (15), and the top bar (17) is removed and released. The net bag (N) can also be pulled out from the upper end of the stretchable guide strut (19) for the net bag, and the disassembled structural member of the framework (F) and the net bag (N) wound into a roll shape can be combined. can be conveniently carried around in a small and compact size.

Furthermore, (T) is a trigger for dropping the movable hanger bar (22), and iron, nickel, ferrite, and other multiple magnetic materials attached and fixed to the movable hanger bar (22) by the mounting bracket (31). It consists of a body (32) and a plurality of electromagnets (34) suspended from the top bar (17) via a suspension fitting (33) so as to detachably attract the magnetic body (32).

In other words, the movable hanger bar (22) is suspended via an electromagnetic trigger (T) from the top bar (17) which is fixed and horizontally mounted at a higher position than this, and in its unpowered state, An electromagnet (34) that generates a magnetic force attracts the magnetic body (32) to temporarily hold the horizontal movable hanger bar (22) in the front open state of the raised mesh bag (N). -ing

Then, when power is supplied to the electromagnet (34) of the trigger (T), the electromagnet (34) does not generate magnetic force, and the attraction force of the magnetic body (32) is released, thereby causing the movable hanger bar (22) to move. will drop by its own weight as suggested in FIG. 6 and instantly close the front opening of the mesh bag (N).

As for the attraction force (magnetic force) of the permanent magnet (13) that suspends the upper surface of the net bag (N), the movable hanger bar that suspends the front opening edge of the net bag (N) 22) is dropped by its own weight due to the release of the electromagnetic trigger (T). It is set to the extent that it falls as if it were torn off.

FIG. 7 is a block diagram showing the electrical system of the capture device according to the above embodiment. Inside the openable/closable control box (B) is a microcontroller (control device) ( 35) and a battery (36) are stored.

On the other hand, in the vicinity of the front opening of the net bag (N) partitioned into rectangles by the framework (F), there is a pyroelectric infrared sensor or ultrasonic sensor, preferably a reflective photoelectric switch (photosensor). A noxious animal intrusion detection sensor (37) is installed, and when the intrusion detection sensor (37) detects a noxious animal that has entered through the front opening of the mesh bag (N), it receives the detection output signal. A microcontroller (control device) (35) supplies power to the electromagnet (34) of the trigger (T), cancels the attraction state between the electromagnet (34) and the magnetic body (32), and the movable hanger bar. (22) is quickly dropped by its own weight to close the front opening of the mesh bag (N).

A horizontal movable hanger bar (22) is traversed so as to drop down from a pair of left and right grounding base plates (14) to the front and rear gaps of fixed support columns (18) for the top bar which are aligned as a pair of front and rear pairs. However, a pair of lock mechanisms (K) are installed correspondingly to the left and right ends of the movable hanger bar (22) projecting from the fixed support (18), so that a captured harmful animal may inadvertently It is preferable to lock it so that it cannot be pushed up.

8 to 10 show the lock mechanism (K) for the movable hanger bar, and (38) is an angle steel stand integrally suspended from the pair of left and right grounding base plates (14). A footrest (39) is welded to the lower end of one side.

(40) is a lifting adjustment bolt screwed into the leg (39), and a cushion rubber stopper (41) attached to the upper end of the bolt is adapted to receive the movable hanger bar (22) from below. It's becoming

In addition, (42) is a floating prevention arm capable of blocking the upper position of the movable hanger bar (22) received by the stopper (41), and is a horizontal arm to the upper end of the other side of the stand (38). It is rotatably pivoted by a fulcrum shaft (43).

In other words, the anti-floating arm (42) works as a so-called check valve that allows the movable hanger bar (22) to drop, but does not allow it to rise after that. (44) is a stop bolt that does not allow the floating, and is designed to receive and restrict the rear side of the rotation fulcrum shaft (43) of the floating prevention arm (42) from above. (45) is a support stay that receives the floating prevention arm (42) from below on the rear side of the rotation fulcrum shaft (43).

The pest trapping apparatus of the illustrated embodiment has the above-described configuration, and when used, the framework (F) of the net bag (N) for trapping is constructed on the ground of the site where pests appear.

In other words, a pair of left and right front corner struts (10f) and rear corner struts (10r) are detachably connected and fixed with piles (46) driven into the ground, respectively, by fasteners (47). While maintaining a stable and robust vertical state from the ground (GL) as shown in 3 and FIG. are joined together by clamp metal fittings (not shown) to form an overall rectangular parallelepiped framework.

As a result, the top bar fixed support (18) and the net bag telescopic guide support (19) are erected from the pair of left and right grounding base plates (14) welded to the lower ends of the front corner supports (10f). Therefore, the front opening side edge of the mesh bag (N), which is preliminarily woven into a U-shaped cross section (almost a rectangular parallelepiped) with only the front opening, is woven into the pair of left and right telescopic guide struts (19). while tying the lower edge of the front opening of the net bag (N) to the ground bar (15) fixedly crossed between the right and left sides of the ground base plate (14). The upper edge of the front opening of the mesh bag (N) is similarly tied to a horizontal movable hanger bar (22) that passes through and horizontally so that it can fall between the left and right sides of the drop guide groove (G) in the support (18). After that, the top bar (17) is fixed horizontally between the fixed struts (18) for the top bar and the stretchable guide struts (19) for the net bag.

In this way, the front opening of the net bag (N) and its framework (F) is divided into rectangular sections, and in parallel with this, a plurality of openings attached to the upper surface (ceiling surface) of the net bag (N) The permanent magnets (13) of the frame (F) are attracted (magnetically attached) to the corresponding vertical beams (11) and horizontal beams (12) of the frame (F), and the lower surface (floor surface) of the net bag (N) is also grounded. (GL) in a suspended state.

Then, the movable hanger bar (22) of the framework (F) to which the upper edge of the front opening of the net bag (N) is bound is moved from the top bar (17) located above the hanger bar (17) to an electromagnetic trigger ( T), the net bag (N) is held in a U-shaped cross-section (almost a rectangular parallelepiped) with only the front side open, and the bait favored by the pest is placed inside the net bag (N) and waits. do it.

If a harmful animal enters from the front opening of the net bag (N) while waiting for assembly of the trapping device, the output signal of the intrusion detection sensor (37) that detects this is sent to the control box (B). is transmitted to a microcontroller (control device) (35) in the inside, and the microcontroller (35) operates and controls the electromagnetic trigger (T), and the movable hanger bar (22) is released by releasing the trigger (T). ) instantly drops and closes the front opening of the mesh bag (N). The pests captured as a result are then culled (eradicated).

In that case, the front opening of the net bag (N) is completely closed by dropping the horizontal movable hanger bar (22). In particular, since the edge of the net bag (N) on the side of the front opening is woven into a pair of left and right telescoping guide posts (19), there is no room for pest animals to escape from the left and right sides of the front opening.

In addition, since the vertical mutual gap between the fallen movable hanger bar (22) and the ground (GL) is narrowly blocked by the blocking bar (23) parallel to the movable hanger bar (22), the net bag (N) There is no danger of the harmful animal escaping forward.

Furthermore, a pair of lock mechanisms (K) are installed correspondingly to the left and right ends of the horizontal movable hanger bar (22) projecting from the top bar fixed support (18) that generates the drop guide groove (G). If the movable hanger bar (22) is locked in its falling position, there is no danger of it being pushed up by pests, which is of great benefit.

As the movable hanger bar (22) falls, the edge of the front opening of the net bag (N) is contracted (folded) in a bellows shape along the stretchable guide strut (19) for the net bag (N). However, the upper surface of the mesh bag (N), which is attracted (magnetically attached) to the frame (F) by the permanent magnet (13), follows the bellows-like contraction (folding) action of the frame ( As a result, the harmful animal is trapped by the net bag (N) as a whole as shown in FIG.

Nevertheless, the net bag (N) does not have any hook metal fittings that intertwine with each other, and is only braided into a simple U-shaped cross section (almost a rectangular parallelepiped), so to speak, so that the harmful animal is unnecessarily injured. There is no need for troublesome work to untangle the entanglement.

It should be noted that although the framework (F) can be disassembled by performing the operations in the reverse order of the assembly, the net bag (N) can be rolled into a roll and carried without disassembling its constituent members finely. It is permissible to limit the decomposition to a certain degree.
