Definitions

  • the present invention relates to an apparatus and method for applying liquid droplets to a particulate material.
  • rotary atomiser discs also known as centrifugal energy nozzles, spinning disc atomisers, or merely spinning discs.
  • Such discs allow a reduction in the volume of chemical liquid or spray utilised, by delivering of low volumes of highly concentrated herbicide, fungicide, fertiliser, etc.
  • These discs operate by spinning at relatively high speed to produce droplets of relatively uniform size, the chemical being fed onto the rotary atomiser disc at a substantially central portion thereof such that the liquid is reduced to small droplets as it moves towards the outside of the disc by centrifugal force.
  • the rotational speed of the disc is between 2000 to 5000 revolutions per minute.
  • Some discs presently used have fine grooves etched in the upper surface thereof, radiating out from the central portion to the extremities thereof so as to enhance the generation of substantially even droplets.
  • the diameter of such discs is between 5 and 10 cm.
  • the Applicant's previous invention defines a droplet applicator which has a plurality of fibres extending substantially perpendicularly to the axis from a substantially cylindrical shaped hub, to form a substantially disc-shaped device.
  • the density of the fibres was progressively increased from an upper surface of the disc-shaped device, towards the lower surface.
  • the disc-shaped device is rotated, such that droplets of the liquid are dispersed from the fibres. Some of the liquid is dispersed from the fibres adjacent the upper surface, and the remainder of the liquid is progressively dispersed by the fibres adjacent the lower surface.

  • the Applicant's earlier invention is not necessarily suited to the application of liquid droplets to particulate materials, such as seeds and grains.
  • the Applicant has therefore devised an apparatus and method which is particularly suited to the application of liquid droplets to particulate materials, such as, but not limited to, seeds and grains.
  • the present invention seeks to provide an apparatus for applying liquid droplets to a particulate material, such as, but not limited to, seeds and grains.

  • said disc-shaped device is a substantially solid disc device, optionally having etched grooves, or similar, in an upper surface thereof.
  • said disc-shaped device includes a plurality of fibres extending substantially outwardly from an axial portion of said disc-shaped device.
  • the density of said fibres increases progressively from a first side of said disc to a second side thereof, wherein, in use, some of said liquid is dispersed from the fibres adjacent said first side, and the remainder of said liquid is progressively dispersed by the fibres adjacent the second side of said disc.
  • said second side of said device is provided with a heavy concentration of said fibres such that it is substantially impervious to said liquid.
  • said disc-shaped device is rotated by an electric motor.
  • the apparatus further includes a housing, within which said discshaped device is provided substantially centrally, wherein said particulate material ingresses through a first end of said housing and egresses through a second end of said housing.
  • the apparatus preferably includes a separator means provided upstream relative to said disc-shaped device, to separate said particulate material supplied via said first end of said housing.
  • said separator means is embodied as a plate-like device.
  • the axis of said disc-shaped device is substantially vertical, and, said particulate material falls past said disc-shaped device by gravitational forces.
  • said liquid is supplied from a container to said disc-shaped device by gravitational forces, by utilising a hand operated pumping devices, under pressurisation provided within said container, and/or via an electric, mechanical or hydraulic pumping device or the like.
  • said apparatus is supplied intermediate aa delivery system and a storage container.
  • said apparatus is portable.

  • a user 1 holds the apparatus 2, used for the supply and distribution of liquid herbicide, fungicide or pesticide.
  • the apparatus 2 includes a droplet applicator 3 provided at one end of a wand 4 to supply chemical liquid from a container 5.

  • Fig. 2 is illustrated an enlarged view of the droplet applicator device 3, and is shown including a disc-like member 7 which is formed of a central hub 8 having a plurality of fibres 9 extending therefrom in a radial manner.
  • the central hub 8 is connected via a shaft
  • the motor 11 is attached via a support 12 to the wand 4.
  • Liquid pesticide, herbicide, or fungicide is supplied within the wand 4 via tubing 13 to the upper surface 14 of the disc 7.
  • the liquid 15 is then supplied towards the central portion of the disc 7, such that, during rotation of the disc about the shaft 10, the liquid flows under the action of centrifugal forces along the fibre elements 9, such that the centrifugal forces fling droplets out along the fibres in a narrow spectrum of size to the rim and beyond.
  • the disc and accompanying motor are mounted on the end of a wand 4, such that liquid can flow from a backpack arrangement under gravitational forces.

  • a spreader plate 24 may be provided such that as the seed falls and hits the spreader plate, it is directed over the edges of the spreader plate, towards the second end 26 of the housing 27. As the seed of grain passes past the intermediate portion of the housing 31, and generally past the spinning disc 20, liquid droplets being sprayed generally outwardly of the spinning disc 20 become applied to the particulate material.
  • Fig. 3 shows a spinning disc which may be of a form as described in the Applicant's previous invention, whereby a plurality of fibres extend substantially outwardly from the axial portion of the disc-shaped device, the disc-shaped device may alternatively be embodied as a substantially solid device.
  • the apparatus described in Fig. 3 is generally provided in a manner between a seed delivery system 28 and a seed container 30, such that the flow of the particulate material and the liquid to be applied thereto may be provided under the forces of gravity due to the orientation of the device, the device need not necessarily be oriented in this manner.
  • the means for supplying the seed or grains or other particulate material, together with means for supplying the liquid to be applied thereto may, alternatively, be supplied using mechanical, electrical and/or hydraulic forces, particularly if the apparatus is disposed in such a manner that gravitational forces cannot be partially or fully utilised.
  • liquid supplied in the apparatus of the invention may include insecticides, fungicides, fertilisers or biological inoculants, and the particulate material may preferably be grains, seeds or the like.

Abstract

Cette invention a trait à un procédé d'application de gouttelettes liquides sur des matières particulaires (29) ainsi qu'à l'appareil correspondant. Cet appareil comporte un dispositif en forme de disque rotatif axialement (20) pulvérisant vers l'extérieur des gouttelettes de liquide. Cet appareil comporte également des moyens permettant l'apport séparé de matières particulaires (28) une fois passé le dispositif en forme de disque (20). Au fur et à mesure de leur passage à travers les gouttelettes de pulvérisation, les matières particulaires s'imprègnent de celles-ci. Cet appareil se révèle des plus utile pour appliquer des herbicides, des fongicides, des engrais, etc.
