Abstract

The invention relates to agriculture, in particular to devices for protecting against hail of grape plantations. The purpose of the invention is to improve the convenience of opening and closing the hail protection nets. During the operation of the device during a thunderstorm, the gradient-proof net 1 is brought to the working position, tensioning the wire 7 of the device to open and close the nets. The wire 7 is moved in the direction of application of force, and the wire 8, which is connected with the wire 7 by a cable 9 thrown over the roller-roller 10, and in the opposite direction. Since the wires 5 and 6 are rigidly fixed on the wires 7 and 8 and movably with the help of rings 12 on the supporting wires 11, they also move from the middle of the row in different directions and act by the holders 13 of the grids attached to the wires 2. In this way, the hail protection grid 1 is opened and occupies a working position. The folding of the nets 1 is carried out in reverse order. 4 il. S (L Yu P 74 fi.Z

The invention relates to agriculture, in particular to devices for protecting against hail of grape plantations.

The purpose of the invention is to increase the convenience of closing gradient shields.

FIG. 1 shows a device for protection against hail of agricultural plants in the working position; FIG. 2 - the same, assembled; in fig. 3 - wire frame with supports and the drive of the cable-block system in the working position; in fig. 4 - the same, in the assembled position.

The device for protection against hail of agricultural plants has a grad-protection grid 1, slung over a longitudinal wire 2, which is drawn along the tips of the extreme 3

During the thunderstorm period, the grid 1 is brought to the working position, for which the wire 7 of the cable-drive drive is pulled, while it moves towards itself, while at the same time the wire 8 moves from itself to the roller 10. Since the longitudinal wires 5 and 6 are rigidly fixed on the wires 7 and 8 movably — on the supporting wires 11 with the help of rings 12, they also move in different directions from the middle of the row and thus the grid 1 opens and occupies the working position, after which the wire 7 is fixed one of

The transverse wires 7 and 8 are part of the cable-block drive of the device for opening and closing the gradient shields, interconnected by a flexible link - a cable 9 and attached by extreme supports 5 with the ability to move using a roller roller 10 "parallel to the transverse wires 7 and 8 chickpea and rigidly fixed on all supports bearing transverse wire 11, to which movably with the help of rings 12 attached longitudinal wires 5 and 6.

On the longitudinal wire 2 with equal pitch and in staggered order, the grids holders 13 are placed in rows, with one end of the holders 13 pivotally using a ring 14 fastened. and falls between rows of vine plantations, which in turn prevents damage to plants.

This device works reliably with any wind direction and falling hail.

If necessary, assemble a city grid, t, e. fold it, release the wire 7 and pull the wire 8. The longitudinal wires move back to the row of plantations, the grids holders 13 slide along the wires 5 and 6, and the gradient mesh folds.

Claims (1)

40 claims A device for protection against hail of agricultural plants, containing longitudinal wires, is fitted on a longitudinal wire 2, and the other 5 along the tops of the supports and carrying the long end has a bend 15 and is supported by coatings in the form of gradient protection nets on additional wires 5 or 6. Holders 13 for supports 3 or 4, instead of a bend, have an elongated loop - a ring that covers additional longitudinal wires 5 and 6. and transverse wires, located on the sides of the device and stretched below the tops of the supports, and devices for opening and closing the gradient protection nets, around the holders of the grids 13 of the grids are attached the gradient protection grid 1. In this case, the length of the holders 13 chosen so that their curved ends are somewhat interposed between the holders 12 of the adjacent row, thereby sharply reducing the gap between the inner edges city protection inclined mesh sheets 1. The device works as follows. During the thunderstorm period, the grid 1 is brought to the working position, for which the wire 7 of the cable-drive drive is pulled, while it moves towards itself, while at the same time the wire 8 moves from itself to the roller 10. Since the longitudinal wires 5 and 6 are rigidly fixed on the wires 7 and 8 movably — on the supporting wires 11 by means of rings 12, they also move in different directions from the middle of the row and thus the grid 1 opens and occupies the working position, after which the wire 7 fixed by one of known methods. In the event of hail falling, the latter rolls down on the inclined towels - gradient net 1 and spills into the gap between them and falls between rows of vineyards, which in turn prevents damage to the plants. This device works reliably with any wind direction and falling hail. If necessary, assemble a city grid, t, e. fold it, release the wire 7 and pull the wire 8. The longitudinal wires move back to the row of plantations, the grids holders 13 slide along the wires 5 and 6, and the gradient mesh is folded. Invention Formula Device for protection against hail of agricultural plants, containing longitudinal wires, stretched to the tops of supports and carrying coatings in the form of gradient protection nets and transverse wires, located on the sides of the device and stretched below the tops of the supports, and a device for opening and closing the gradient protection nets, so that, in order to increase the convenience of operation, it is equipped with on both sides of each longitudinal wire, stretched along the tops of the supports, additional longitudinal wires, the ends of which have rings, covers31 The transverse wires, tensioned below the tops of the supports, and hinged on each longitudinal wire of the grid holders in the form of pieces of wire, the free ends of which have bent ends to support them on additional longitudinal wires, and the device for opening and closing gradoprotective grids is made located on each side of the device, two placed in parallel 198014 one above the other wires, the ends of which are connected on one side by a flexible connection, covering a block attached to one of the extreme supports, and the end parts of the additional wires located on one and the other side of each longitudinal wire stretched along the tops the supports are rigidly connected respectively to the top by means of them and the lower wires of the device for opening and closing the gradient shields. fie .- / 9iv. 2 12 Editor N.Shvydka FIG. four Compiled by S.
