(54) DEVICE FOR PROTECTION AGAINST THE GRAD OF GRAPE PLANTING

one

This invention relates to agriculture.

A device for protection against hail of grape plantations is known, which includes supports, anti-gradient mesh with a mechanized troso-block system and drive 1.

A disadvantage of the known device is the low speed of bringing the grid to the working position.

The purpose of the invention is to increase the speed of bringing the grid to the working position and the efficiency of the temperature protection.

This goal is achieved by the fact that in a device for protection against hail of grape plantings, including supports, a hail mesh with a mechanized troso-block system and a drive, the gradient mesh is made of two inclined canvases, located assembled along a row of plantations and equipped with weights fixed on the longitudinal sides of the canvases.

FIG. 1 shows a gradient mesh in the working position; in fig. 2 - the same, assembled; in fig. 3 - device for protection against hail of grapes

plantings; in fig. 4 — intermediate support assembly with a guiding device; in fig. 5 - extreme support node.

The grid protection grid 1 is thrown over the top wire 2, stretched over the heads of the intermediate supports 3, and fastened on it in such a way that its edges cover the upper part of the plants on both sides of a row in an inclined plane.

On the supports 3, guiding devices are installed, consisting of a yoke 4 and tightly tensioned between it and the head of the support 3 of the guide strings 5 made of wire with metal rings 6 strung and sliding along them.

The slack edges of the gradient protection grid 1, attached to the ring 15, are fastened with the supports 3, and the weights 7 are fixed to their lower part.

The hail protection net is connected by a rope 8 with cable branches 9 with stirrups 10 mounted 20 on the heads of the supports 3.

Claims (1)

Traction lines 8 rows are branches of the main cable 11, which extends perpendicularly of the traction lines 8 at the head of the vineyard. The main cable is suspended on the extreme supports 12, on hooks 13, and connected to the winch 14. Traction the ropes 8 are attached to it by flexible cables 15 with a hook system 16. For the stability of the supports 12, a wire is fastened with 17 wires 18 along their heads. All ropes can be made of galvanized wire and a flexible cable can be inserted into the bends. Instead of rollers, you can use the stirrup and hooks made of round galvanized steel. The haze protection net is brought to the working position with the help of the winch 14 and the weights 7 t shaking it down. It is folded by means of a traction rope 8, which slides with its cable branches 9 along stirrups 10 and t up the ends of the branches with sliding rings 6 attached to them, which, together with the cable branches, lift and fold the slack edges of the net. The cable 8 stops moving and stops when the rings 6 reach the top point. A rope 11 is driven by a winch 14 with a ratchet. At the end of the folding of the mesh protection net, the winch drum is stopped and the ratchet is locked with a dog. As the pawl is raised, the winch drum 14. begins to rotate in the opposite direction from the weight of the weight to the net 1 of the weights 7, and the net opens. The cable branches 9, when moving the main cable 11, slide through the system of hooks 16, lift and fold the extreme sagging edges of the net. The device does not interfere with the operation of the means of mechanization. -Width traverse 4-60 cm and does not come out of the dimensions of a number of yes plants. The main cable 11 is suspended on extreme supports 12, the height of which reaches 2.2 m. Wire 18 also runs at a height of 2.2 m. Instead of an electric winch, you can install a manual winch, since the course of the main and haul cables does not exceed 1 -1 , 5 m. Thanks to the use of such a device to protect against hail of grape plantings, the speed of bringing the nets into working position increases, the efficiency of grading protection increases, and the design of the hail mesh is simplified. The invention The device for protection against hail of grape plantings, including supports, protivogradnuyu grid with a mechanized troso-block system and drive, characterized in that, in order to increase the speed of bringing the grid to its working position and increase the effectiveness of gradient protection It is located in assembled form along a series of plantations and is supplied with cargoes fixed on the longitudinal sides of the canvases.
