JPH07144894A - Forklift truck with harmful animal expelling device - Google Patents

Abstract

PURPOSE:To generate the ultrasonic wave at the time of charging a charger and emit the ultrasonic wave outside from a transformer to expel harmful animals of a food warehouse or the like, and to improve the efficiency of a charger itself by connecting an ultrasonic wave generating source to a transformer of a charger loaded on a forklift truck. CONSTITUTION:In a forklift truck 1, a fork 4, vertically moved along a mast 3, is arranged in a front part of a car body 2. The car body 2 is loaded with a charger inside thereof. In this case, a high frequency generating circuit is connected to a transformer 5 of a charger. In the case of charging a charger at night, the high frequency generating circuit is also electrified, and the generated high frequency is transmitted to the transformer 5, and thereafter, the high frequency is emitted outside from the transformer 5. Harmful animals such as rats are thereby expelled from a food warehouse or the like to safety and securely prevent the damage of food or the like by harmful animals. Furthermore, high frequency is utilized to improve the efficiency of a charger itself to downsize a rectifier or the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forklift with a harmful animal control device for controlling harmful animals such as rats that eat food in food warehouses with a simple device.

[0002]

2. Description of the Related Art Conventionally, in food warehouses and food factories, in order to prevent damage from harmful animals, buildings have been constructed without gaps or poisoned.

[0003]

Even if the above-mentioned preventive measures are taken, there is a problem that the damage caused by the harmful animals cannot be prevented.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a forklift truck equipped with a charger, which is harmful during charging by controlling with the control frequency and high frequency of the charger. It is configured to secondarily generate over 20,000 frequency signals that animals dislike, from a transformer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described with reference to FIG.
Is a perspective view when embodying a reach forklift,
FIG. 2 is an electric circuit diagram for generating a high frequency.

In FIG. 1, a reach type forklift 1 is shown.
Includes a vehicle body 2, a mast 3 in front of the vehicle body 2, and a fork 4 that moves up and down in front of the mast 3, and a transformer 5 and a high-frequency generation circuit 6 are mounted in the vehicle body 2.

Referring to FIG. 2, an electric circuit diagram will be described.
The high frequency generating circuit 6 and the transformer 5 are connected to the plug 7, and when the plug 7 is connected to a power source side plug (not shown), more than 20,000 frequency signals generated from the high frequency generating circuit 6 are transmitted to the transformer 5. Then, the transformer 5 generates more than 20,000 ultrasonic waves outside.

[0008]

The present invention has the following four effects due to the above-mentioned configuration. I. By using a high frequency, the efficiency of the charger itself is increased, and it is possible to downsize the transformer, rectifier 8 and the like used in the charger. B. Because it uses ultrasonic waves, pests escape,
Carcasses do not enter food as they do when using poisons. C. Since charging is done at night, it is effective because it matches the time when the pest appears. D. It is harmless to the human body.
