Tunnel sprayer for rows of orchards, vineyards or other plants

摘要

The tunnel sprayer for rows of orchards, vineyards or similar, is of the towed, carried or self-propelled type, and comprises on the uprights of the portal (3) opposed shields (S1, S2) where each shield is provided with at least a vertical spraying bar (B) with an adjacent vertical delivery chamber (6) of air under pressure in the same direction of flow, and it is provided, laterally and parallel to this, with a vertical intake chamber (10), connected to said delivery chamber by means of one or more generators (V) of air under pressure, like fans, turbines or similar. Said chambers are arranged in inverted and opposed position in the said shields (S1, S2), in such a manner that to the delivery chamber for the air under pressure in one shield (S1) there is opposed the intake chamber on the other shield, and vice versa. At least the delivery chamber (6) for the air under pressure is structured in such a manner to reduce the internal losses of head or charge and in such a manner that its discharging mouth (106) which is opened toward the row, presents a limited width, so that the same chamber acts as a distributor and buffer and/or compensator, so that from its discharging mouth comes out an air flow with values of flow rate and pressure distributed in uniform manner and constant along the whole height of the mouth as much as possible.
