[Function] Next, to explain the function of the present invention, when you want to drive the fan to provide a suitable amount of wind around the shrubs, first turn on a switch (not shown) (this can be done manually or automatically). ), rotate the fan.

[0015] The rotation of this fan generates an appropriate amount of wind and air flow around the shrub.

[0016] The purpose is to avoid a situation where frost is likely to form through such air flow, that is, a no-wind situation, and prevent frost damage.

[0017] In the fan rotation situation as described above,
If the anti-frost fan device is a fixed type, it will be installed at a predetermined position on the rail and directed towards the bushes in the field, or if it is a mobile type, it will move forward along the rail and move toward the ridge. There is a method of blowing down in sequence (including a method of blowing in the horizontal direction, the same applies hereinafter), or a method of blowing down sequentially in a direction different from the ridge direction in the case of the above-mentioned fixed method and moving method.

[0018] Also, at this time, the area benefiting from frost protection can be expanded by oscillating the fan over a wide area.

Of course, the depression angle of the fan can also be adjusted as appropriate.

[0020] If the anti-frost fan device becomes a hindrance during agricultural work, it can be moved to a suitable location or moved outside the rails, thereby making each work easier, or reducing the effort required for pole construction, etc. can be eliminated.

[0021] The movement of the anti-frost fan device can be carried out either manually or by automatic control, and with automatic control, it is possible to save labor and manpower.

[0022] In addition, in the case of a fixed installation method, by moving the installation position of the entire frost protection fan device, it is possible to effectively cope with different frost formation conditions depending on the year and weather conditions even within the same year. It is.
