摘要

The invention relates to a device (1) for protecting plants (P), crop fields or other fields, from natural events of a destructive nature, comprising supporting poles (10), a crossbar (20) supported by said supporting poles (10), first arms (40) rotatable between a closed position, in which they are substantially parallel to the poles (10) or perpendicular to the ground, and an open position in which they project from the poles (10) on one side of the device (1) and at least a first net (30) that can be moved away from said crossbar (20) and/or downward, said net (30) being available in a gathered position, in which it is at least partially wound or gathered in proximity of the crossbar (20), or in a spread out position, in which it is at least partially spread out on top of the first arms (40) to cover the goods to be protected, said first arms (40) being able to engage the net (30) to be shifted between the closed position and the open position when the net (30) is unwound or wound between the gathered condition and the spread out condition.
