  • the interval delimited by the stirrup-shaped iron-plate 17 is also utilized as a housing for a driving wheel 20, the shaft 21 thereof being supported into bearings 22, supported with no difference by said iron-plate 17 or base I9.
  • the shaft 21 is provided with coupling 23 enabling the connection of the same to a driving hook, for example to the driving hook of a farming tractor, eventually through a connecting shaft (not represented).
  • the driving wheel 20 is connected to shaft 10 by means of a belt 24, and said belt is thus included inside the support delimited by the stirrup-shaped iron-plate 17 which is entirely placed into concavity 7 and housing 7a of the tank 1, only the coupling clutch 23 protruding from said tank.
  • the arms of the iron-plate 17 can be connected together through one or several grate-shaped or perforated metal sheets represented in mixed lines as 25 and 26 on FIG. 1, whereby the shaft 10, driving wheel 20 and belt 24 are entirely covered.
  • the revolution concavity 4 is used to place a turbine baffleplate 27.
  • the baffle-plate 27 includes one or several revolution sectors 27a (FIGS. 1 and 5) being applied directly against concavity 4 and thus ensuring the centering of said baffleplate in relation with said concavity.
  • said baffle-plate delimits volutes of which the ends thereof are provided with nozzles 27b with circular openings, one of them appearing on FIG. 1.
  • the number of nozzles 27b is determined by the utilization of the device, said number can be, for example, within the range of I to 6.
  • the drawings show that the turbine baffle-plate 27 is only placed by jointing into concavity 4.
  • a peripheric edge 28 is designed all around baffle-plate 27 to constitute in some way a collar, and a seal-tight gasket 29 is placed between said edge and the corresponding portion of the back-side of housing 3.
  • FIGS. 1 and 5 also show that the baffle-plate 27 delimits, in
  • a grate 32 is, for example, made of expanded metal and maintained by struts 33 which are kept against the peripheric edge 28 of the baffle-plate by a spring 34, bearing against a bar 35, the folded ends thereof being fixed by screws, fasteners or any other fixing means 36, connecting the same to the collar 3a and to the jointing edge 2a.
  • Grate 32 which is preferably substantially rigid can be also utilized to maintain connecting tips 37 engaged into openings of nozzles 27b and protruding in order to enable the fixing of tubes or pipes 38 which send the air towards spraying devices (not represented).
  • container 41 forming collector 40 is made of synthetic resin via moulding by rotation, thus enabling said container to be made in one piece.
  • the inner wall of collector 40 delimits a sucking-in nozzle 43 for the air which is sucked-in according to the direction of the arrows by the centrifugal turbine 12.
  • the collector 40 On the lower portion thereof, the collector 40, at least fonns a first tube 45 directed towards the powder 42 and a second tube 46 which can be more or less closed by a flap 47.
  • the front portion of the container 41 has tubular bases 48 for placing plugs or bent atomizers 49, preferably in the number of two, and they can thus be directed towards many directions in view of directing, in the best possible way, the powder which is to be atomized, and according to the cultures to be treated.
  • the container 41 is provided with a filling opening 50, usually closed by a plug 51, to which can be substituted the base 52a of a flexible atomization gun 52.
  • the air which is sucked by turbine 12 through nozzle 43 is pushed-back into collector 40 through the opening (s) 44 and is directed towards the inside of the container.
  • the air coming-out from collector 40 substantially follows a cyclonic motion.
  • the air coming-out from tube 45 and also from tube 46 causes a disturbance causing the powder 42 to be progressively put into suspension into said air and becomes fluidized.
  • the so-fluidized powder is then atomized through either atomizers 49 or gun 52.
  • the device of FIGS. 1 to 4 can either be utilized to spray liquids and atomize powders with not other modification than replacing diffuser 27 by container 41.
