Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for continuously capturing mice.

The inventor has already developed a device that takes advantage of the mouse's habits, ie, angular habit and nesting instinct, to guide the mouse into the interior of an artificial passage. This device can reliably guide mice, but unless the mice ingest the rodenticide within the passageway, a reliable killing effect cannot be obtained.

Therefore, the present invention makes it possible to reliably transport mice that have entered the artificial passageway to a predetermined location using airflow, and actively captures mice inside the artificial passageway. .

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

As shown in FIG. 1, the mouse catching device 1 of the present invention has a plurality of cylindrical artificial passages 3 each having a mouse entrance 2 arranged in a ring shape along the wall surface of a building, etc. A guide port 4 is formed in the guide port 3, one end of a cylindrical guide path 5 is connected to the guide port 4, and a processing device 6 is detachably attached to the other end of the guide path 5. An escape prevention body 9 is connected to the suction port 8 of the pump 7 and can enter the inlet side of the processing device 6 only in the guiding direction.
It is configured by providing.

As shown in FIG. 2, the artificial passageway 3 is, for example, a cylindrical body having a fan-shaped cross section, and the ends thereof are fitted into each other. These plurality of artificial passages 3 are connected in an annular manner along the floor and the wall surface, but they may be connected at regular intervals. One of the artificial passages 3 has a guide opening 4 formed on its outer surface, into which one end of a guide passage 5 is fitted. As shown in FIG. 2, this guideway 5 has an opening/closing body 10 built therein near the guide port 4. This opening/closing body 10
is rotatably supported above by a support shaft 11,
Moreover, the lower end portion is in a state where it can come into contact with the bottom surface of the guideway 5. This support shaft 11 is equipped with a lever 12 at the outer end of the guideway 5, and this lever 12
One end is connected to an electromagnetic plunger 15 via a pin 13 and a rod 14. This electromagnetic plunger 1
5 is attached to the upper surface of the guideway 5, for example.
Further, a pressure sensitive switch 16 is provided on the bottom surface of the guiding path 5 between the opening/closing body 10 and the processing device 6. This pressure-sensitive switch 16 is made of, for example, pressure-sensitive conductive rubber, and functions to detect the pressure when a mouse passes over it and close the electrical circuit.

Further, an escape prevention body 9 is attached to the inlet side of the processing device 6. As shown in FIGS. 3 and 4, this escape prevention body 9 includes two escape prevention plates 17,
These escape prevention plates 17 and 18 are rotatably supported on the inlet side of the processing device 6 by shafts 19 and 20, respectively, and have their lower ends in contact with the bottom surface. One escape prevention plate 17 is provided with a protruding stopper 21, and the other escape prevention plate 18 is provided with a stopper receiver 22 that comes into contact with the stopper 21. These escape prevention plates 1
7 and 18 are made of metal wires to allow air flow.

Now, as shown in FIG. 5, the pressure sensitive switch 16 is connected in series with the relay 23 and timer contact 25 between power supply terminals 26 and 27. Furthermore, a series-connected relay contact 29, a timer 24, a series-connected relay contact 30, and a motor 31 for driving the vacuum pump 7 are connected between the power supply terminals 26 and 27. A holding relay contact 28 is connected to the pressure sensitive switch 16, and an excitation coil 32 of the electromagnetic plunger 15 is connected to the motor 31 in parallel.

Next, the functions and operations of the mouse trapping device 1 will be explained. Because rats move along walls and the like due to their angular habit and nest-building instincts, which have already been described, they instinctively enter the artificial passageway 3 through the rat entrance 2. Although the mouse moves between the artificial passages 3, when it reaches the guide port 4, it attempts to enter the inside of the guide passage 5. This guidance can be performed more reliably by placing bait or the like inside the processing device 6. Here, the opening/closing body 10 opens the inside of the guide path 5 in a non-energized state due to the action of the electromagnetic plunger 15. Therefore, when the mouse enters the guideway 5 and passes over the pressure-sensitive switch 16, the weight of the mouse turns on the pressure-sensitive switch 16. At this time, relay 23 is activated and closes its relay contacts 28, 29, and 30. Therefore, the electromagnetic plunger 15 is actuated instantaneously to pull the lever 12 and rotate the opening/closing body 10 clockwise, thereby preventing the mouse from returning to the inside of the artificial passage 5. At the same time, the timer 24 is activated and the motor 31 is started. Since the motor 31 drives the vacuum pump 7 , the vacuum pump 7 generates a strong air flow flowing from the guide port 4 into the processing box 6 inside the guide path 5 . Therefore, the mice inside the guide path 5 are forced into the processing box 6 by the strong air flow. It is advantageous if the inner surface of the guideway 5 is slippery, since the mouse cannot escape against the air flow. In this way, the mouse passes through the escape prevention plate 9 and heads into the processing device 6. When the mouse rotates the first escape prevention plate 17 counterclockwise, the stopper 21 moves to the stopper receiver 22.
The next escape prevention plate 18 similarly rotates counterclockwise. In this way, the mouse enters the inside of the processing device 6 along with the air flow, but then the escape prevention plates 17 and 18 return to their initial state due to their gravity, so that the mouse cannot escape.
Even if a mouse pulls up the front escape prevention plate 18 and tries to rotate it counterclockwise, the stopper 2
1 abuts against the stopper receiver 22, and this contact portion and the other shafts 19, 20 form an undeformable triangle, so the escape prevention plates 17, 18 do not rotate in any direction. In this way, the mouse is reliably restrained inside the processing device 6. When a certain period of time has elapsed, the timer 24 is activated and the timer contact 25 is turned off, so that the relay 23 is de-energized and the electromagnetic plunger 15 and motor 3 are turned off.
1 automatically stops operation. In this way, the opening/closing body 10 opens the inside of the guide path 5 again and prepares for the next mouse capture. Note that the mice inside the processing device 6 are processed by appropriate means.

In the above embodiment, the opening/closing body 10 is provided inside the guideway 5, but this opening/closing body 10 may be omitted. Further, although the escape prevention plate 9 of the above embodiment is constructed by combining two escape prevention plates 17 and 18,
This escape prevention plate 9 may have the same configuration as the opening/closing body 10 and the electromagnetic plunger 15.

The present invention provides the following unique effects.

Because rats instinctively use the inside of the guideway as a passage, rat excrement and parasites are not scattered outside, and nest building between walls and ceilings can be reliably prevented, and communication lines and electric wires can be prevented. Bites such as these are reduced. In addition, rats that enter through the guideway entrance are forced into the processing equipment by strong air currents, ensuring that the rats are captured and quickly disposed of, eliminating the need for other rats to evade them. .
