The invention relates to agriculture. - i, .. The purpose of the invention is to increase the reliability of the device,

In FIG. 1 shows a device for protection against hail in a working position, a general view; in FIG. 2 - the same, in the idle position: in FIG. 3 - section of the support column when the device is in the working position; in FIG. 4 - the same with the inoperative position of the device; in FIG. 5 - 7 - sections aa, bb and bb in figure 4; in FIG. 8 - node I of figure 4 (option); in FIG. 9 is a section GG in FIG. 8.

The device includes supports 1 with a longitudinal section 2, on each of which there is a supporting element 3 connected to the anti-hail net 4 and, using the hinge 5, mounted on the movement mechanism b made in the form of a kinematic screw-nut pair, the nut 7 having a tip 8 , The device is equipped with a guide 9 located on the outer surface of the support 1, a longitudinal section 2 of which is made through, along the entire height of the movement mechanism b, and a second tip 8 is fixed on the nut 7, while the supporting element 3 having An A-shape, by means of a hinge 5, is mounted on a U-shaped bracket 10, fixed rigidly by means of a fastener 11 to the tips 8 of the nut 7. One end 12 of the supporting element 3 can slide thanks to the element 13c1 by the hinge 14 in the guide 9. Direction The binder 9 is fixed to the support 1 rigidly by the element 15 and provided with a latch 16 for the working position of the device. The anti-hail net 4 is supported by cables 17, and the supports 1 are provided with heads 18. The movement mechanism 6 installed in the support 1 at its base 19 is connected to the rotation mechanism 20.

The device is brought into operation from the control panel.

By activating the rotation mechanism 2fj of the screw of the movement mechanism 6, the nuts 7 with the tip 8 are moved downward. Together with the latter, the U-shaped brackets 10 are also fixedly fixed to them, which

It facilitates the movement of the support element 3 with the anti-hail net 4. Simultaneously with the movement of the support element 3, its one end 12 slides along the guide 9 until it contacts the latch 16, which completes the bringing the device to its working position.

The device is brought into an inoperative position in the reverse order and is fixed after the nut 7 contacts the head 18 of the support 1.

Using this device provides quick overlap of rows

vineyard before the onset of hail with great rigidity of the structure as a whole., m IV
