Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multipurpose control device for preventing frost damage and preventing the arrival of birds such as crows and murk birds in orchards grown in greenhouses.

2. Description of the Related Art In orchards, harvest is greatly affected by frost withering due to late frost during flowering and bird damage due to the arrival of crows and muk birds during harvest. To prevent this, heating was used in the house to prevent late frosts, and to prevent the birds from coming in, the nets and explosion noise were used to prevent damage.

However, it is difficult to judge the late frost by weather forecasts such as radio and television, and there is a drawback that the fuel cost increases.
Also, the net for bird chasing has the drawback that not only is it a lot of work, but the explosion noise also becomes less effective as the bird gets used to it.

[Means for Solving the Problems] As a countermeasure against frost and frost damage to late frost, the applicant first installed a fan in the house to agitate warm upper air and cold air near the ground surface to prevent frost damage. He invented a method of doing so and has great effects. However, no measures have been taken against bird damage. As a result of earnest research on this point, the applicant has noticed that birds are sensitive to electromagnetic waves, and disturbs the electromagnetic waves to prevent birds from approaching.

The climatic condition that causes frost damage occurs when the ground is cooled by the radiant cooling at night and the temperature of the atmosphere becomes higher than the surface temperature. Therefore, in order to prevent this, if the temperature of the ground surface can be maintained at 0 ° C. or higher, it can be prevented. According to the meteorological data so far, when the ground surface temperature was -3 ° C at the time of frost, the temperature of the atmosphere 8m high was + 3 ° C.
The present invention installs a fan on the ridge of the house to stir the atmosphere to raise the temperature of the atmosphere near the surface of the house, and also to prevent the temperature of the surface of the ground from becoming 0 ° C. or lower by sprinkling water on the ground to prevent frost damage. In addition, the permanent magnets are attached to the blades of the fan, and when the fan rotates, the magnetism generated from the permanent magnets is disturbed, an abnormal magnetic field is generated, and the bird does not approach.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the accompanying drawings. FIG. 1 and FIG. 2 are embodiments of the present invention, and FIG. 3 is an enlarged explanatory view of essential parts. In the figure, (1) is a rain shelter house for fruit trees, and a fan (3) held by a pipe (2) is vertically rotatable on a steel frame (4) on the ridge of this house (1). Installed. The shaft (2) is detachably attached so that it can be removed when it is not needed. The blade (7) of this fan (3) has several permanent magnets (8) as shown in FIG.
Is installed. Reference numeral (6) shown in FIG. 2 is a sprinkler for spraying water on the ground surface at night to prevent freezing, but it is needless to say that it can be used for irrigation and fertilization like a normal sprinkler. Since the fan (3) of the present invention is intended for measures against slow frost and bird damage, its use period is from the flowering period to the harvesting period, and in the case of cherries, for example, 4 During the period from mid-March to early July, the fan is removed for storage during other periods. The fan (3) is a motor (not shown) as a measure against slow frost.
In the daytime, the power is turned off and the wind force allows it to rotate freely.

According to the present invention, a fan (3) is mounted on a house to stir the atmosphere to raise the temperature of the atmosphere near the surface of the house, and water is sprinkled on the ground to reduce the temperature of the surface to 0 ° C or lower. The permanent magnets (8) are attached to the blades (7) of the fan (3) to prevent the frost damage, and when this fan rotates, the magnetism generated from the permanent magnets is disturbed and an abnormal magnetic field is generated, which causes birds. It has the effect of not approaching.
