Abstract:
Machine for spraying phytosanitary products for plants in rows, comprising a carriage (10) which is pulled longitudinally along the rows by a tractor and which is mounted on wheels, characterised in that the carriage (10) houses an air compression system (11) and a store (12) for phytosanitary products which are diffused in a circuit of air ducts (101) and a circuit of phytosanitary product ducts (102), respectively, which are supported by a framework (20) of vertical arches (30) which are sized internally so as to be flush around the external perimeter of the plants to be treated, the air conduction circuit (101) leads at each arch into the hollow tubular section of the main air guide (32) of a series of abutting fluid-tight deflectors (50) which comprises, for each deflector, a fine output slot (33) through which a thin jet of air can pass, which jet is subsequently guided over the deflector wing (31), at the end of which, for some deflectors, a nozzle (41) for spraying phytosanitary liquid of the phytosanitary product circuit (102) sprays treatment product which is carried by the air flow onto the plant to be treated inside the projecting part of the arch.
