Description

The present invention relates to an animal damage control device.

Preventing damage caused by wild animals is essential in farm fields, and in the past a wide variety of measures were used, from scarecrows to loud noise blasters. Nowadays, electric fences and other devices are used to enclose the perimeter of fields and run high voltage electricity through them to prevent harmful animals from entering the fields. In addition, hunting associations and others carry out vermin extermination, using hunting rifles and traps.

However, while scarecrows and noise blasters can be used effectively and can provide some improvement, they can gradually become less effective as the target pests become accustomed to them. In addition, while it is very important to remove undergrowth, which can cause electrical leakage, the positioning of the equipment makes it difficult to do so, and there is a rare chance that the equipment may become entangled and damaged during undergrowth removal. Furthermore, depending on the environment, such as electrical leakage or broken wiring, the electric shock may not be effective enough to repel the target pests.

Even in the case of pest control carried out by hunting associations and other groups, there are many issues, such as the difficulty of hunting in mountainous areas, the hunting period, and a shortage of personnel.

The capture trap includes a cage body having two passable openings, a door attached to the opening so as to be freely opened and closed, a door holding means that changes between a holding state that holds the door in an open state and a release state that releases the open state, an operating means that operates the door holding means, and a camera sensor that monitors the cage body. When the camera sensor detects an animal inside the cage body, it determines the direction of movement and size based on image recognition through the camera sensor, and the operating means operates to change the door holding means from the holding state to the release state, whereby the door moves by its own weight or a spring to close the opening.

Furthermore, the invention of claim 3 is characterized by having a communication means for notifying the user that the operating means has been activated and the capture trap has been set in motion.

According to the invention of claims 1 and 2, the animal damage prevention device of the present invention is able to attract the target vermin into the trap by conforming to the characteristics of the vermin, providing high trapping performance, and by using a sensor to determine the position of the target vermin within the trap when it is captured, the door can be closed safely, preventing the target vermin from getting caught in the door and being killed or injured, and furthermore, as long as it does not encourage other intrusion routes other than the vermin entrance, management work such as weeding around the vermin intrusion prevention device does not need to be strict.

Furthermore, if the device of claim 3 is adopted, the operating means is activated by the communication means, making it possible to notify the user early on that the capture trap has been activated, thereby preventing the captured pest from becoming weak.

FIG. 1 is an overall perspective view showing the first and second embodiments of the device of the present invention. FIG. 1 is an explanatory diagram showing details of the device according to the first embodiment of the present invention. FIG. 10 is an explanatory diagram showing details of the device according to the second embodiment of the present invention. FIG. 1 is an explanatory diagram showing details of the device according to the first and second embodiments of the present invention when claim 3 is used. (Examples 1 and 2)

Below, a preferred embodiment of the present invention is described in detail with reference to the drawings.

The pest intrusion prevention device 1 is installed around the perimeter of the field 4, and is made of high-strength synthetic fiber netting, wire mesh, etc., to physically or psychologically prevent the intrusion of target pests.

When it comes to pest control, even if you install a pest intrusion prevention device 1 that appears to be perfect at first glance, pests will almost always try to get in by finding a gap to get in, damaging the device, or digging soil directly underneath it.

Therefore, the pest intrusion prevention device 1 is provided with a pest entrance 2. This is to mislead the target pest into thinking it is the easiest place to enter.

The capture trap 5 is selected to be of a size and strength appropriate for the target pest, and is set up so that it leads from the pest entrance 2 to the field 4.

The trap 5 is characterized by having a cage body 13 with two passable openings 6, a door 7 attached to the opening 6 so as to be freely opened and closed, a door holding means 8 which can be switched between a holding state that holds the door 7 open and a release state that releases the open state, an actuation means for actuating the door holding means 8, and a sensor 10 on the cage body 13 for detecting the moving direction and size of the animal, and when the sensor 10 detects an animal, the actuation means 9 is actuated and the door holding means 8 changes from the holding state to the release state, whereby the door 7 moves by its own weight or a spring to close the opening 6.

In addition, multiple sensors 10 are used to obtain detailed information about the direction of movement and size of the pest inside the cage body 13, and to operate the trap safely.

Furthermore, by managing multiple sensors 10 in a complex manner, if a pest accidentally enters the field 4, the user can make detailed settings in advance, such as whether to capture the pest as it exits or to let it go.

The embodiment shown in Figure 2 is an animal damage prevention capture device in which the animal detection sensors installed in front and behind the cage body 13 in parallel along the animal's entry direction in the first embodiment are replaced with a camera sensor 11.

By using a camera sensor 11 in the device, it is possible to set more precise capture timing, etc.
In addition, by using cameras, it is possible to record the situation and observe the type and behavior of pests.

By effectively setting traps in farm fields, this device can intentionally capture targeted pests, eliminating the need to aimlessly target wild animals. In addition, the use of sensors provides an opportunity to select the targeted pests without directly affecting their lives. Furthermore, by linking farm managers, hunters, and meat processors, it can contribute to a supply line of safe, consistent, and fresh wild bird and animal meat compared to hunting in the mountains and fields.
