<p>The equipment distributes a liquid, partic, a pesticide, in a current of air. It has a tubular sleeve (1) for connection to the device generating the current, and into which an injection tube (8) extends. The tube is mounted on the outer end of a regulator (10-15), to which a feed pipe (17) for the liquid is connected. The tube discharges into a jet pipe (9), to which a conical expanding centre piece (18, 19) is connected. Blades (20) are mounted on the periphery of the latter, omega that the air current causes it to rotate. A cone (21) is mounted in its centre, and has peripheral triangular blades (22). Cone and centre piece rotate together in bearings.</p> |
