Abstract

The vine treatment device consists of a tank (1) carried on a metallic frame and a spraying pump (2), which is driven through a gearbox (3), which also drives a fan (4), which produces the air flow and sucks in the leaves.

Description

The present invention relates to a device for stripping the

  vine plantations, by making simultaneously a treatment directed on the bunch of grapes which is essential, and which heals the seeds of grapes,

injured by leaf stripping.

  This function, of stripping the vines in front of the fruit surface, is more and more recommended by the wine technicians, to obtain a bunch of grapes without rotting, as well as the work of spraying localized on this grape, the adapted chemicals, to counteract seed rot. The stripping, is traditionally done by a simple stripper, and the corresponding treatment, is done by a second pass with a

  sprayer, or is sometimes overlooked.

  When the treatment is not done punctually, one can find rot on the grape. When the chemical treatment is done after stripping, the spraying will be less directed, or dispersion of the product

  in the wild, and cost of a second pass.

  The device according to the invention overcomes this drawback. According to a first characteristic, it in fact comprises a propeller or turbine sprayer, driven by an agricultural tractor, used to spray the chemical spray. The sprayer therefore includes a tank for the chemical reserve, a spray pump to take the chemicals into the nozzles or venturis, directed on the fruit vegetation of the vine. Conventional sprayers have a propeller or a turbine attached transversely to the sprayer, to create a breath of wind, which will position the spray in the vegetation of the village. This new sprayer, therefore with the propeller or the turbine, positioned laterally to the tank, which allows it to strip the desired part, and to propel the chemical spraying on the bunch of grapes discovered of the troublesome leaves. According to particular embodiments - the pump which is actuated by the power take-off of an agricultural tractor, directly drives a multiplier box, exiting with an angle of 90,

  which itself, ensures the rotation of the propeller or the turbine.

  - This propeller or this turbine, makes a rotational movement in a stator, which ensures the call of air used to suck the leaves, and to propel the

spraying through an air channel.

  - the propeller or the turbine are provided with blades, placed at the end of the blades or

  blades, used to cut the aspirated leaves.

  -_2 - The attached drawing illustrates the invention

  Figure I shows in section, the device of the invention.

  Figure 2 shows in section, a variant of this device.

  With reference to these drawings, the device comprises a tank (1), fixed on a metal frame. A spray pump (2) which drives a speed multiplier (3). The gearbox, rotates the propeller or the turbine (4). This propeller or this turbine (4) operates in a stator (5) which ensures the suction of air and sheet. This stator (5) is provided with an air inlet (6), an air outlet for cut sheets (7) and an air channel (8) serving to propel the chemical spraying. The propeller or turbine, is

  equipped on the suction side with blades (9), used to cut the leaves.

  The propeller or turbine (4) rotating in the stator (5) ensures an air intake through the inlet (6), which is discharged through the outlet (7) and through the air channel (8). The propeller or turbine (4), equipped with blades (9) therefore ensures,

  1 5 the air intake for spraying, and for cutting the desired leaves.

  The device according to the invention is particularly intended to save time during the stripping of vine plantations, since this device avoids ironing for a treatment against decay of the grape bunches because

this is done simultaneously.

  This device also results in a less significant loss of chemicals, therefore respect for the environment, and a shorter time to apply these products to the grape bunches, since directly in contact with the fruits discovered by the fact of stripping simultaneous. -3 -

Claims (4)

  1) Leaf stripping device for vineyard plantations, and simultaneous treatment on the grape bunches, characterized in that it comprises a tank (1) fixed on a metal frame, accompanied by a pump spray (2).   2) Device according to claim 1, characterized in that the pump drives a speed multiplier (3) 3) Device according to claim 2 characterized in that the gearbox ensures rotation of the propeller or the turbine (4) operating in   a stator (5), and ensuring an air and sheet suction.   4) Device according to claim 3, characterized in that this same stator is provided with an air inlet (6), an air outlet for sheets   cutouts (7) and air channel (8) used to propel the chemical spray.   ) Device according to claim 3, characterized in that the propeller or the turbine (4) is equipped on the suction side with blades (9), used for cutting leaves.   6) Arrangement according to one of claims, ensuring suction   air through the inlet (6), which is discharged through the outlet (7) and through the air channel (8).   The propeller or the turbine (4), equipped with blades (9) therefore ensures the suction of air   for spraying, and for cutting the desired leaves.
