DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trapping apparatus for small animals such as rodents and cockroaches which can collect and treat harmful small animals such as rodents and cockroaches living in house facilities.

[0002]

2. Description of the Related Art Among pests that inhabit facilities such as houses, buildings, and warehouses, rodents and cockroaches are particularly strong in fertility and difficult to control. Therefore, conventionally, various means have been devised for capturing and eliminating these. For example, for capturing mice, bait, traps or traps with traps called so-called mouse traps, and adhesive plates are often used. However, rats are sensitive to human odors and have a high learning ability, so that they often stay away from devices that humans touch or feel dangerous, and their effects often do not last. Recently, for example, a long tunnel-like artificial passage with a poison plate in the center has been developed using the cornering behavior of rats (the habit of traveling in the corner) and the habit of living and nesting in dark places. In the corner, etc.
For example, a mouse is guided into a duct of an air shooter, and a ball-shaped carrier is fed into the duct by utilizing a difference in air pressure, and the mouse is pressure-fed to a processing device by the carrier to be processed. Apparatus (Patent No. 263072)
No. 4) has also been developed. On the other hand, in order to control cockroaches, fumigation, spraying, poison bait, adhesive plates, and the like of drugs have been widely used.

[0003]

However, since these conventional extermination means separately capture or treat rodents and cockroaches, respectively, it is necessary to control various parts of house facilities in order to exterminate both of them. These extermination means must be installed separately, and fumigation, spraying, poison bait, adhesive plates, etc. of the drug have only temporary effects, making replacement and collection not only complicated, but also In some cases, the extermination means interfered with each other, and did not improve the extermination effect on both rats and cockroaches. The present invention has been made in order to solve the above-mentioned problems, and accordingly, an object thereof is to provide a small animal capturing device such as a rat and a cockroach that can capture both a mouse and a cockroach in one device and collectively process them. To provide.

[0004]

The present inventors have focused on the fact that rats and cockroaches have common habits such as the above-mentioned habitability and habit of preferring dark places. As a result of intensive studies on the means for capturing and batch-treating at the present invention, the present invention has been reached. Claim 1 of the present invention is to provide at least a rat cockroach on the inner floor surface of a tunnel having an inside diameter through which a mouse can pass. There is a drop floor on which small animals can fall, and a capture container is attached below the drop floor, and at least beside the drop floor so that the detection beam crosses the floor of the drop floor. Two sets of light sensors are arranged, at least one of which is a high position light sensor arranged so that its detection beam crosses a height in the range of 10 mm to 50 mm above the floor, and At least one set of The detection beam is 0.5mm on the floor
A low-position light sensor disposed so as to cross a height within a range of 2 mm, and when at least one of the high-position light sensor and the low-position light sensor detects a small animal such as a rat or cockroach, And a small animal trapper such as a rat or cockroach, wherein the small animal is dropped into the trapping container by opening the dropping floor, and immediately after dropping, the dropping floor is closed.

[0005] Since the small animal trap of the first aspect of the present invention has a tunnel through which at least a mouse can pass, the rodents have a common habit such as a preference for a dark place and a habit of traveling to and from corners. And cockroaches both prefer to enter this tunnel. A dropped floor is provided in the tunnel, and at least two detection beams cross the floor of the dropped floor. This detection beam is provided at two levels, the higher one is at a height that can detect a rat, and the lower one is at least at a height that can detect a cockroach, so that either a rat or a cockroach is detected. The drop floor opens even if it is dropped, and these small animals can be dropped and caught in a capture container. When the small animal falls, the drop floor closes immediately so that the captured small animal cannot escape and the device is ready for the next capture.

[0006] The trapper for small animals such as rats and cockroaches
A door is provided at the entrance of the tunnel, and near the door inside the tunnel, an entrance optical sensor is disposed such that the detection beam crosses a height within a range of 10 mm to 50 mm above the floor of the tunnel, It is preferable that the door is always open, closed when the entrance light sensor detects a small animal, and opened when the dropped floor is opened.

[0007] Since the entrance light sensor is provided at a height where the detection beam does not detect cockroaches but only the rat, the door is closed only when the mouse enters the tunnel. As a result, even if the mouse that has entered the tunnel feels danger and tries to turn back, the door at the entrance is closed and the egress is cut off, so that the mouse advances toward the dropped floor. Then, the mouse reaches the dropped floor and is detected by the high position light sensor or the low position sensor. When the dropped floor opens and closes, the door at the entrance opens to prepare for the next capture.
The door does not close when the cockroach enters the entrance, so that the rat can enter even if the cockroach enters first.

The tunnel is preferably provided with a means for dropping a small animal such as a cockroach traveling along the wall surface on at least a part of the inner wall. The cockroaches can travel along the tunnel wall, and may pass without being detected by the low-position light sensor. If a means for dropping a cockroach traveling along a wall surface is provided, the probability of detection by the low-position optical sensor increases, and the capture rate improves. The means for dropping the small animal may be an electric shock wire provided on the inner wall of at least a part of the tunnel, or a group of brush-like projections having a sharp point. When using the wiring for electric shock, it is only necessary to drop the cockroach instead of killing it,
The voltage may be as low as several volts, and may be direct current or alternating current.

Preferably, the tunnel extends linearly or bent bidirectionally across the dropped floor, and both bidirectional ends are open. Rats and cockroaches have a habit of favoring dark places in the house facility and going around the corner, so if you install a tunnel in the corner of the house facility and open it in both directions,
They can enter from both directions, and rats have the habit of entering tunnels, increasing the chances of capture. In addition, if the tunnel is extended linearly or bent, the distance between the entrance of the tunnel and the drop floor can be increased, which helps to eliminate the caution of small animals.

[0010] At least a part of the tunnel,
A vertical pipe may be formed from the level of the dropped floor and may be hung down. An entrance may be formed below the vertical pipe, and a cable or a chain may be installed inside the vertical pipe. In particular, rats have the habit of preferring vertical passages and have fun, so by forming vertical tunnels with ropes or chains attached, they guide rats in house facilities to the attic etc. and improve the capture rate Can be done.

[0011] A taxiway that is inclined or hangs down may be provided outside the entrance of the tunnel so that small animals such as rats and cockroaches can easily reach the entrance. Especially when installing the capture container on the ground,
Since the difference between the level of the dropped floor and the ground is large, the tunnel may be lowered or hung to connect the dropped floor to the ground.However, the taxiway is installed outside the tunnel, and the small animal is placed at the entrance of the tunnel. May be easily reached.

[0012] A shielding plate for a mouse return may be mounted on the outer periphery of the tunnel. Depending on the installation condition of the tunnel, the rat may jump and ride on the tunnel without entering the tunnel. In order to avoid this possibility, a mud-back shield plate is effective.

[0013] The above-mentioned capture container may have means for treating small animals such as rats and cockroaches in the container. Here, the “small animal treatment” includes, for example, a method of collecting the small animals so as not to escape and taking them out alive, and a method of killing and taking them out. If the capturing container has the small animal processing means in the container, small animals captured regardless of life or death can be collectively taken out of the capturing container and discarded. When a small animal is to be taken out alive, the small animal processing means may be a cage, a bag, an adhesive plate or the like placed in a capture container. In the case of killing and taking out, it is preferable that it includes at least one of cooling, heating, for example, suffocation with water or gas, contact poisoning, poisoning, and electric shock. Cooling, especially freezing, is advantageous because the killed small animals can be removed without spoilage.

[0014] The capture container may have a small animal carrying means for carrying out the small animal captured to an external small animal processing apparatus. In the case where the capturing container itself has the small animal processing means, it takes human labor to remove the captured small animals such as rats and cockroaches from the capturing container, and there is a possibility that odor and the like may become a problem. From this point of view, it is preferable to provide a small animal carrying means for carrying out the captured small animal to an external small animal processing apparatus without human intervention.

This small animal carrying means is preferably an air shooter for carrying out small animals such as rats and cockroaches by a difference in air pressure. According to the air shooter, the small animals are transported to an external small animal processing device by blowing or sucking them to the air shooter immediately after the capture without being held in the capture container for a long time. Can also prevent communication with other rats by emitting an alarm sound of an ultrasonic wave, thereby improving the capture rate and automating the capture and processing.

The air shooter has a transporter for pushing the small animal in the transport tube, and the transporter is transported by pressurization or depressurization to provide the small animal at one or both ends of the transport tube. It is preferable that the small animal processing apparatus is transported to the small animal processing apparatus. Thus, both the rat and the cockroach can be transported to the small animal processing apparatus in a lump by a single transport of the transporter.
Transferring a carrier suitable for the transfer tube by pressurization or depressurization is more efficient than transporting an indefinite rat or cockroach by direct pressurization or decompression. In this case, the small animal processing apparatus may be installed on only one side of the transport pipe of the air shooter, and the small animal may be pushed to the small animal processing apparatus only once by one reciprocation of the transporter. A processing device may be provided to push small animals to each small animal processing device each time the carrier is transported one way.

In the pneumatic shooter, a transport pipe is disposed along a ceiling of a house facility, the tunnel extends vertically downward from the level of the dropped floor, and an entrance is opened in a floor of the house facility. Is preferred. By arranging the transport pipe of the air shooter along the ceiling of the house facility,
The efficiency of the use of house facilities can be prevented from lowering due to pipes and traps for small animals such as rodents and cockroaches. Angularity, nature that prefers dark places,
It can be guided to the ceiling and captured using the vertical running behavior. In particular, since a plurality of small animal traps can be connected to one air shooter, permanent small animal trapping equipment can be constructed in a large-scale building or warehouse facility.

In the trap for small animals such as rodents and cockroaches of the present invention, the tunnel may be provided along the electric wire. Rats and cockroaches also prefer to travel along electric wires, so if a tunnel is arranged along this electric wire and an entrance is provided in the middle of the electric wire, rats and cockroaches can easily enter this tunnel. It is possible to prevent the wire from being damaged by rats.

In the trap for small animals such as rodents and cockroaches of the present invention, the trapping container may be buried under the floor of a house facility. In this case, the tunnel can be arranged along the floor of the house facility, so that the tunnel can be installed, for example, at the corner of the kitchen facility without any hindrance.

In any of the above small animal traps such as rodents and cockroaches, when at least the high-position optical sensor detects a small animal, display means for displaying the detected information or the integrated number of captured animals may be provided. preferable. Since the small animal trap of the present invention for detecting small animals such as rodents and cockroaches detects small animals by electrical means using an optical sensor, this detection information is electrically processed to capture the information at the site or on a centralized control panel. , The capture information such as the capture time and the number of captured animals can be displayed. Since rats are prolific, catching a small number of animals will prevent large rat harm. It is also important to judge the location of small animal traps such as rodents and cockroaches. From this perspective, it is extremely important to determine the number of rats that have been captured in managing house facilities.

As shown in a sectional perspective view of FIG. 2, the capture unit 10 has a drop floor which is opened downward and open so as to allow small animals to fall inside a tunnel 30 having an inside diameter through which a mouse can pass. 11 and 11 are provided. A capture container 12 is mounted below the dropping floors 11, 11, and both ends of the capture container 12 are connected steplessly to a transfer pipe 51 of an air shooter 50 having an inner diameter equivalent to that of the capture container. In addition, both ends of the tunnel 30 are connected to the tunnels 30A and 30B, respectively.

A drop floor 1 is provided on the side wall of the tunnel 30.
Two sets of optical sensors 15 and 16 are disposed so that the detection beams 13 and 14 cross the floor surfaces of the optical sensors 1 and 11, respectively. Is disposed so as to cross a height H within a range of 10 mm to 50 mm on the floor of the vehicle. This optical sensor 15 is hereinafter referred to as a “high position optical sensor”. The other optical sensor 16 is disposed so that the detection beam 14 crosses a height L within a range of 0.5 mm to 2 mm above the floor of the drop floor. This optical sensor 16 is hereinafter referred to as a “low position optical sensor”. The high-position light sensor 15 and the low-position light sensor 16 and the dropped floor drive device (not shown) are all connected to the computer 20.

An electric wire 17 for electric shock is disposed in a transverse direction on a wall surface formed in a semi-cylindrical shape of the capturing unit 10 in parallel with a ground wire, and a voltage (12 volts) for dropping cockroaches at all times is provided. ) Is applied.

This capture unit 10 is a computer
When at least one of the high-position light sensor 15 and the low-position light sensor 16 detects a small animal, the dropped floor 11 opens downward to capture the small animal. Container 12
After dropping, immediately drop the floor 11
Is to be closed.

When the mouse enters the tunnel 30 through the tunnel 30A or 30B and passes over the dropped floor 11, the capturing unit 10
Since the detection beam 13 crossing the height (H) within the range of 0 mm to 50 mm or the detection beam 14 crossing the height (L) within the range of 0.5 mm to 2 mm on the floor is blocked, the high position optical sensor 1 is provided.
5 or the low position sensor 16 detects this, and the computer 20 opens the drop floors 11, 11, and the mouse falls into the capture container 12. Even if the rat tries to climb up from the opening, it cannot escape because the dropped floors 11 and 11 are immediately closed by the command of the computer 20 or the self-recovering force of the dropped floor driving device (not shown). The mouse that has fallen into the capture container 12 is immediately conveyed to the small animal processing device 70A or 70B by the action of the air shooter 50 described in detail later, and is subjected to a freezing process.

When a cockroach enters the tunnel 30 and travels on the dropped floor 11, the low-position optical sensor 16 intercepts the detection beam 14 that crosses the height (L) within the range of 0.5 mm to 2 mm above the floor. This is detected. This causes the drop floors 11 and 11 to open, so that the cockroaches fall into the capture container 12 and are captured. On the other hand, the cockroaches traveling along the wall surface of the tunnel 30 come into contact with the electric wire 17 for electric shock, receive an electric shock, drop and fall on the floor 11. At this time, since the cockroach is not dead, after falling, it crawls on the drop floor 11 to block the detection beam 14 and is detected by the low-position optical sensor 16, and the dropped floors 11, 11 are opened and captured in the capture container 12. . In any case, since the drop floors 11 and 11 are immediately closed, the cockroaches cannot escape from the capture container 12. The cockroaches in the capture container 12 are conveyed to the small animal processing device 70A or 70B by the action of the air shooter 50 and subjected to a freezing process.

As shown in FIG. 1, the tunnels 30A, 30
B extends continuously in each direction to the tunnel 30 of the capture unit 10 and each tip is open. The tunnel 30 </ b> A extends straight from the tunnel 30 along the upper surface of the transfer pipe 51 of the air shooter, and has an entrance portion 31 opened above the transfer pipe 51. The entrance portion 31 is provided with an electric door 32, and is located in the vicinity of the entrance portion 31 inside the tunnel 30A at a distance of 10 mm from the floor surface of the tunnel.
The entrance light sensor 33 is disposed so that the detection beam crosses the height (H) within the range of 50 mm.

This door 32 is always open,
When the rat enters the tunnel 30A from the entrance 31 and shuts off the detection beam, the entrance optical sensor 33 detects this,
Computer 20 connected to the entrance light sensor 33
Is closed by the instruction of. Further, when the dropped floors 11 and 11 are opened and closed, the door 32 is immediately opened by a command from the computer 20 which detects this.

A mouse that has entered the tunnel 30A from the entrance 31 is detected by the entrance optical sensor 33, and a door 32
Is closed so that it cannot be turned back and moves forward, and is detected by the high position optical sensor 15 or the low position sensor 16, and the drop floors 11, 11 open and fall into the capture container 12. As soon as the dropped floors 11 are closed, the computer 20
To enter the standby state for the next capture. Since the detection beam is at the high position, the entrance part optical sensor 33 does not detect even if a cockroach enters, so that the door 32 does not close due to the entry of the cockroach.

On the outer periphery of the tunnel 30A, a shield plate 34 is mounted near the entrance 31 so as to be turned back. Due to the presence of the shielding plate 34, the rat traveling on the transport pipe 51 of the air shooter cannot jump over the tunnel 30 </ b> A and travel.
You will enter A.

The tunnel 30B extends from the tunnel 30, bends once in a horizontal plane, and then descends from the level of the dropped floor 11 as a vertical tube 35, the lower end of which is a guide box installed on the floor of a house facility. 40. An entrance 41 is opened in the guide box 40, and the entrance 41 has
An electric door 42 that opens and closes in response to a command from the computer 20 is provided, and a
The entrance light sensor 43 is disposed so that the detection beam crosses the height (H) within the range of 0 mm to 50 mm. The entrance light sensor 43 is connected to the computer 20. A chain 36 is mounted inside the vertical tube 35.

The door 42 is always open, but when a mouse enters the guide box 40 from the entrance 41 and cuts off the detection beam, the entrance optical sensor 43 detects it and is closed by a command from the computer 20. . Also this door 42
When the dropped floors 11 open and close, the computer 20
It is opened immediately by the order of.

When the mouse enters the guide box 40 from the entrance 41, the mouse is detected by the entrance optical sensor 43, and the door 42 closes behind, so that the mouse cannot be turned back and moves forward.
It rises in the vertical pipe 35 along the chain 36, enters the tunnel 30, is detected by the high position optical sensor 15 or the low position sensor 16, and the drop floors 11, 11 open and fall into the capture container 12. The opening and closing of the dropped floors 11 causes the computer 20 to immediately open the door 42 and enter a standby state for the next capture. Since the detection beam is at the high position, the entrance optical sensor 43 does not detect even if a cockroach enters from the entrance 41, so that the door 42 does not close due to the entrance of the cockroach.

In the air shooter 50, small animal processing devices 70A and 70B each composed of a freezing container are connected to both ends 51A and 51B of the transport pipe 51, respectively. A ball-shaped carrier 53 is inserted inside the carrier tube 51 so as to be freely circulated. The carrier 53 is provided at both ends 51 of the carrier tube.
Advancing is stopped by stoppers 54 formed at A and 51B, respectively, so that the flow can reciprocate only inside the transfer pipe 51. The stopper 54 is provided in an annular shape on the inner wall of the transport pipe 51 so as not to block the flow of small animals. Then, optical sensors 55A and 55B are attached at positions where the transport element 53 has been stopped by the stoppers 54 at the respective ends 51A and 51B of the transport pipe 51, and the presence or absence of the transport element 53 is detected. Is sent to the computer 20.

The ends 51A and 51B of the transport pipe 51 are connected to the small animal processing apparatuses 70A and 70B, respectively. Each of the small animal processing apparatuses 70A and 70B is a freezing container having a manual opening / closing door 71, and a small animal receiver 72 is freely inserted therein. Also, exhaust pipes 73A and 73A are respectively provided from the top of the small animal processing apparatus.
B extends, and both of these exhaust pipes 73A and 73B are connected via a switching valve 74 controlled by the computer 20.
Vacuum tank 75 depressurized by a vacuum pump (not shown)
It is connected to the. The exhaust pipes 73A and 73B are respectively provided with opening valves 7 controlled by the computer 20.
Open to the atmosphere via 6A and 76B.

The computer 20 has a display device 21. The display device 21 displays the cumulative number of times the dropped floors 11 have been opened and closed, and determines that the mouse has fallen when the high position optical sensor 15 detects a small animal and the dropped floors 11 open and closes. The integrated value is displayed as the number of captured animals.

In the air shooter 50, in a standby state, the transporter 53 is connected to one end of the transport pipe 51, for example, 51.
It is placed on the B side. Here, when the high-position optical sensor 15 detects a small animal and the drop floors 11 open and close, the computer 20 determines that the mouse has fallen into the capture container 12 and adds and displays the number of rats captured on the display device 21. At the same time, the opening valve 76B is opened (the opening valve 76A is closed), and the switching valve 74 is driven so that the small animal processing device 70A and the vacuum tank 75 are conducted. As a result, the small animal processing apparatus 70A is brought into a decompressed state.
The air flowing in from 6B transfers the transport element 53 toward the end 51A of the transport pipe 51.

The carrier 53 passes through the trapping container 12 during the movement, and reaches the stopper 54 in a state where the rat dropped into the trapping container 12 is stopped. The rat conveyed at this time passes over the stopper 54 and the small animal treatment device 70A
Falls into the small animal receiver 72 and is frozen therein.

When the carrier 53 stops at the position of the stopper 54, the optical sensor 55A detects this and transmits the arrival of the carrier 53 to the computer 20. Computer 20
Switches the switching valve 74 to the exhaust pipe 73 based on the arrival information.
It returns to the neutral position in which neither A nor 73B is conducted, closes the opening valve 76B and enters the standby state. During this time, the reduced pressure in the vacuum tank 75 is restored.

Thereafter, when the mouse falls again into the capturing container 12, the computer 20 adds and displays the number of the captured rats on the display device 21, opens the opening valve 76A, keeps the opening valve 76B closed, and switches the switching valve 74 to the small animal processing apparatus. Driving is performed so that 70B and the vacuum tank 75 are conducted. As a result, the carrier 53 is moved to the end 51B of the carrier tube 51 with the mouse.
And the mouse falls into the small animal processing apparatus 70B and is frozen therein.

The rats captured in the capturing container 12 as described above are transported one by one by the transporter 53, and are fed into either the small animal processing apparatus 70A or 70B for freezing processing. On the other hand, when a cockroach is captured in the capture container 12, the carrier 53 is not driven each time. The captured cockroaches are pushed by a carrier 53 that is circulated when the mouse is captured, carried to one of the small animal processing apparatuses 70A and 70B, and subjected to freezing processing. Further, the carrier 53 may be circulated periodically to carry the captured cockroaches irrespective of the capture of the rat. The number of cockroaches captured is indicated on the
This is schematically displayed as a difference between the integrated number of open / close operations of 1, 11 and the number of mice captured.

Since the rats and cockroaches in the small animal receivers 70A and 70B are frozen, they do not rot during the storage period. Therefore, the opening / closing door 71 may be opened periodically, or according to the number of catches displayed on the display device 21, and the small animal receiver 72 may be taken out and separately processed such as incineration.

In the air shooter 50, a plurality of capture units 10 can be mounted and arranged in series on one transport pipe 51, so that an efficient small animal capture system can be constructed in a large warehouse or the like. In the small animal capturing system of the above embodiment, both ends 51 of the transport pipe 51 are provided.
A and 51B are provided with small animal processing devices 70A and 70B, respectively. The small animal processing device is installed only at one end, and the transporter 5 is transported every time a small animal such as a mouse is transported.
It goes without saying that 3 may return to the other end to enter a standby state.

The capture vessel 101 is composed of a water pipe, one of which is connected to a water injection valve 102, the other of which projects into a drain groove 103, and a cage 104 is connected to a tip thereof. The capture container 101 and the cage 104 are disposed below the water surface of the drain 103.

A plurality of tunnels 105 are arranged on the floor G, and the inner floor of each tunnel 105 has
A drop floor 106 on which small animals can fall is provided, and the lower part of the drop floor is hollow and connected to the capture container 101. Further, on the side of the dropped floor, the high-position optical sensor 107 and the low-position optical sensor
8 are provided. When a small animal such as a rat or a cockroach blocks the detection beam of one or both of the high-position light sensor 107 and the low-position light sensor 108, the drop floor 106 opens, and immediately closes when the small animal falls into the capture container 101. ing.

When a small animal enters the tunnel 105 and one or both of the high-position optical sensor 107 and the low-position optical sensor 108 detects this, the drop floor 106 opens, and the small animal falls into the capture container 101. The small animal drowns because the capture container 101 is filled with water. When the water injection valve 102 is opened at an appropriate time, the small animal (or its remains) drowning and floating in the capture container 101
Are flowed under water pressure and collected in the cage 104. Since the small animal is completely dead in the cage 104, the cage can be easily removed from the drain 103 and disposed of. This small animal trap 100 for rats and cockroaches,
Since the part other than the tunnel 105 is not exposed on the floor, a small animal capturing system that is effective but does not impair the appearance of the room can be constructed.
