Definitions

  • TECHNICAL FIELD The present invention relates to a crop spraying device.
  • a device comprising a tank containing a parasiticide in powder form; a pneumatic circuit having at least one outlet communicating with the outside; and an impeller for drawing the parasiticide from the tank and feeding a gaseous stream containing the parasiticide along the pneumatic circuit to the outlet.
  • known devices of the type described above have various drawbacks, mainly due to the gaseous stream, on issuing from the outlet, being partly dispersed in the atmosphere, thus reducing the effectiveness of the treatment, as well as polluting the environment and endangering the health of the operator.
  • Device 1 indicates as a whole a device for spraying crops (not shown) and mounted, in the example shown, on a carriage la drawn by a known agricultural machine not shown.
  • Device 1 comprises a tank 2 containing a parasiticide in powder form; and a pneumatic circuit 3 for feeding the parasiticide from tank 2 to two outlets 4 (only one shown in the drawing) , each of which communicates with the outside and is substantially in the form of a sector of given size.
  • Circuit 3 comprises an impeller 5, which is powered by a power take-off of said agricultural machine (not shown), draws the parasiticide from tank 2, and feeds a gaseous stream of air and parasiticide along two tubular conduits 6 (only one shown in the drawing) , each of which is fitted on its free end with one of outlets 4, and has a respective flexible intermediate portion 7 by which to orient relative outlet 4 about at least two perpendicular axes 8, 9, of which axis 8 is a substantially vertical axis, and axis 9 a substantially horizontal axis.
  • the amount of parasiticide drawn from tank 2 by impeller 5 is controlled selectively by a known regulating valve device not shown.
  • Device 1 also comprises a tank 10 containing a liquid product - in the example described, water; and a hydraulic circuit 11 for feeding the water from tank 10 to four nozzles 12 (Figure 2) , two of which are fitted inside one outlet 4, and two inside the other outlet 4.
  • the water issuing from nozzles 12 is atomized by the gaseous stream fed along conduits 6 and through outlets 4, so as to expel into the atmosphere an atomized parasiticide mixture, which is charged electrically at outlets 4 by means of an electric device 13 ( Figure 2) comprising, for each outlet 4, a respective metal plate 14 located close to relative nozzles 12 and powered electrically to charge the atomized parasiticide mixture, issuing from relative outlet 4, electrostatically with an electric charge of given sign.
  • each outlet 4 is substantially cylindrical, and has a number of nozzles 12 equally spaced about a longitudinal axis of the outlet 4, and an annular metal plate mounted coaxial with the longitudinal axis and which is chargeable electrically. Operation of device 1 is easily deducible from the foregoing description with no further explanation required.
