Description
“GUIDE AND FASTENING DEVICE FOR PLANT SUPPORT WIRES”
DESCRIPTION
The present invention relates to a guide and fastening device for plant
training wires, particularly suitable for use in the ltural field.
BACKGROUND OF INVENTION
In the viticultural field, a well-known ce is to prearrange vine support
structures consisting of rows of poles driven into the ground so as to form rows
of grapevines. The poles are spaced at regular distances and are connected at
a certain height from the ground by at least one fixed horizontal wire, called
“carrying wire” or “training wire”.
On the two poles located at the head of each row, called “head poles”, is
also ed at least one pair of parallel wires arranged on respective sides of
each pole in the row. These wires are commonly called “containment wires” or
“movable wires” e, during the different phases of cultivation of the ,
they are moved to different heights above the ground to contain and arrange
the growing vegetation according to a desired configuration. This is a
ularly laborious operation.
Italian Patent application PN2010A000023, filed by the same s of
the present application, describes a fastening device for the “movable wires” of
a row of plants, in particular grapevines, which foresees connecting the
movable wires to vertical guide elements associated to the end or head poles.
The ends of the movable wires are fastened to mounting means that are
inserted and can slide within the guides formed in the vertical guide elements,
so as to modify the height of the movable containment wires and adapt it to the
growing vegetation.
This solution is advantageous, but it does not offer the possibility of
optimizing at another moment the position of the training wire and of the second
wire, and of any third fixed wire, if present, that are located higher than the
training wire having a support function. er, it does not completely solve
the m of pruning the vine shoots after the grapes have been harvested. In
effect, automatic machines have been built that move along the rows and are
provided with means for lifting and cutting the vegetation. However, these
machines cannot perform satisfactorily in the area at the head of the rows, that
is in the area that goes from the head pole to the first plant support pole.
European Patent Application EP 2 324 700 A1 describes an elastic
compensation device for the movable wires in ltural systems. This device
includes a first fastening element for connection to a head pole in the row and a
second fastening element to receive at least one pair of movable wires. The first
and the second fastening elements are interconnected by an elastic element
and are both arranged at the same end of said elastic element, so as to apply
only a compression force on the . Wire-tensioning means are also provided
in opposite positions with t to the elastic element to engage the pairs of
containment wires and to make it possible to adjust their tension. However, the
solution described in Patent Application EP 2 324 700 A1 is not adaptable to a
“training wire” and is bound to the use of a specific tensioning means.
SUMMARY OF THE ION
The main ive of the present invention is to propose a guide and
support device for the “training wires” on rows of grapevines that makes it
possible to make the most te use, that is, as far as the ends of the rows
of vines, of the automatic machines for pruning vine-shoots.
In on, an objective of the invention is also to be able to vary and
optimize the position of the support wires in a simple manner and as necessary.
Another objective of the present invention is to propose a device that is
simple and quick to install, being made up of a minimum number of component
pieces.
A still further objective of the t invention is to propose a single guide
and support device for both the ng wires and the containment wires that is
ularly rational, t and solid, so as to support all types of stresses to
which it may be subjected.
Alternatively, it is also an object of the invention to at least provide the
public with a useful choice.
Any one of these objectives are achieved with a tensioning device having
the characteristics specified in the claims of the present patent.

ED PTION OF THE INVENTION
The head portion of a row of plants, in particular grapevines, shown in
figures 1A to 10, es a head pole PT and an intermediate pole PI. The
head pole PT is driven into the ground, generally inclined from the vertical plane
and is suitably braced by relative bracing wires FV. The intermediate pole PI is
instead driven into the ground in a substantially vertical position.
On the head pole PT is mounted a compensation device 1, to which are
fastened the ends of the containment wires FC. The compensation device
includes a pair of guides 2 within which slide tive fastening means 3.
The device 1 must guarantee that the guides 2 are as much as possible
vertical, so as to enable the displacement of the containment wires FC.
To the fastening means 3 are fastened the ends of the containment wires
FC, which are kept spaced apart laterally so as to guide between them the
grown vegetation and follow it as it grows upward. The guides 2 are connected
and fastened to the head pole PT by means of brackets 4 and collars 5.
The detailed description of this solution is omitted, as reference to the
constructive details is made in Patent Application AOOOO23 previously
mentioned.
According to the invention, the compensation device 1 includes a further
guide 6 that is associated to the guides 2, in an intermediate on between
them. In the guide 6 are mounted sliding means 7, similar to the fastening
means 3. The ends of the training wires FP are connected to the fastening
means 7, so as to allow the vertical displacement of the wires.
Naturally, the vertical positioning of the wires can be assured with known
fastening means, such as pins to insert in relative holes in the guides; such pins
are preferably connected to the guides through chains, so as to avoid scattering
them. As an alternative, elastic split pins or similar means can be used for this
purpose.
Preferably, the ng wires FP and the containment wires F0 are
connected to the ing means 3 and 7 h cushioning means 8 of
known type.
In particular, in a second embodiment, the compensation device 1 is made
adjustable by connecting the vertical guides 2 and 6 to the head pole PT
through a curved bracket 9 provided with a ity of equally spaced holes 10.
pondingly, the vertical guides 2 and 6 are provided with holes 11 near
their upper ends. The holes 10 on the bracket 9 and the holes 11 on the guides
2 and 6 receive a threaded pin 12 that is locked by a nut 13.
This solution makes it possible to adapt the position of the compensation
device 1 and the tensioning of the training and containment wires to adapt them
to the characteristics of the g vegetation in the row of vines.
The new on was studied to make it more advantageous to carry out
the pruning and defoliation operations performed with automatic machines,
allowing the vertical displacement of the training wires FP, while keeping them
parallel to the ground.
In fact, up to now the ends of the training wires FP were connected in fixed
positions on the head poles PT, and thus in the n of a rows of plants
between the head pole PT and the first intermediate pole PI the training wires
FP were inclined upward so as to be guided toward the pruning machines.
Consequently, the pruning of the plants was irregular in the head portions of the
rows of plants, or had to be carried out manually, demanding time and effort
from the operator.
With the solution according to the invention, there is also the advantage of
enabling the ng wires FP to be displaced vertically, even independently of
the pruning ion, so as to simply adapt the system to the type of training of
the specific plants.
