Abstract

The invention relates to agriculture, in particular to viticulture in the covering area. The invention provides a grape trellis device to facilitate the process of covering the bushes for the winter, including the use of synthetic film materials. To achieve this goal, the vine trellis is suspended by means of a flexible rope on the supporting pillars of a special profile and raised or lowered as necessary with the help of hand winches. The role of supporting intermediate pillars is performed by special trellis wire delimiters, allowing them to be set at a certain distance between themselves and above the soil. 1 il.

Description

The invention relates to agriculture, in particular to viticulture in the covering area.

A vine trellis is known, consisting of hinged pillars, having the ability to be forcedly laid on the ground or installed in a vertical position by means of hauling trellis wire fixed in a special way on the supporting pillars.

The disadvantages of such a trellis are: the laboriousness of laying operations on the ground and setting it in an upright position; breakage of the trellis wire from frequent bends; damage to the bushes.

The purpose of the invention is to develop a grape trellis construction that would greatly facilitate the release of grape bushes from the trellis wire before putting the bushes under the ground or sheltering film and other materials.

This goal is achieved in that the trellis wires attached to the movable elements installed in the extreme support pillars, together with the delimiters and tension elements, are hung on the rope tensioned between the support pillars and allow the trellis to be raised and lowered in a vertical plane, because Wire end delimiters can be connected to fasteners installed in the soil.

FIG. 1 shows a trellis assembly; in fig. 2 shows section A-A in FIG. one; in fig. 3 - wire stops.

The tapestry consists of two extreme support posts 1, trellis wires 2, rope 3, delimiters 4 trellis wires, nodes 5 fastening the delimiters to the soil, flexible hanging elements 6, tension elements 7. The support poles are equipped with two blocks 8 and 9, which serve to tension the rope and lift the trellis, respectively, a sliding element 10 of the T-section (Fig. 2) sliding into the hollow body of the post (Fig. 2), which serves to fasten the wires, raise and lower

trellis winches. The attachment points are installed in the soil and in the upper part are equipped with a ring for fixing wire delimiters. Wire delimiters (Fig. 3) are a plate with an inner slot having jagged edges 11.

For assembling the trellis, two extreme support columns 1 are installed at the required distance from each other, along with the slider wire mounting points placed in the grooves, which slide freely in the vertical direction, and blocks 8 and 9. On top of the blocks 8, a rope 3 is attached, fixed to the post by means of the tension element 7. Flexible elements 6 are fastened to the rope at the required distance from each other, to which the trellis wire 4 delimiters are suspended. At a similar distance in the soil, mount points 5 are installed, the rings of which are left slightly above the soil level. The delimiters at the lower free end are fixed to the rings. The trellis wires 2, with their ends, are fastened to the attachment points and installed by means of the jagged edges of the slotted fence at a certain height above the ground level. The tensioning elements 7 and the winches regulate the degree of tension of the system.

The installation works as follows.

Example I. In the spring, prior to the beginning of the growing season, a vine is attached to the trellis wires as described above. If necessary, the tension of the wire is corrected.

Example 2. Before covering the rod with tensioning elements 7 and winches, the tension of the rope 3 is relaxed. The delimiters 4 lower ends are released from the rings of the attachment points 5. The trellis wires 2 are freed from the rod and the trellis is raised with winches above a row of vines. The bushes are bent to the soil and covered by one of the known methods. The absence of intermediate support columns in a number allows one to stretch a synthetic film or other material over the bushes, which substantially facilitates the covering process.
