Definitions

  • the invention relates to a new system that creates an electrical field between static-charged agricultural pesticide droplets and target tree parts (leaves and branches), enabling the sprayed droplets to reach the target directly.
  • Turbo atomizers are widely used in the application of pesticides to fruit trees and vineyards.
  • fruit trees and vineyards to be sprayed are higher than turbo atomizer, due to this, the droplets produced by pressure in classic type turbo atomizers are transported to the target surfaces with the air current provided by an atomizer fan.
  • the airspeed used, tree height, the spaces on the rows and the pesticide success vary depending on the vegetative period of the tree.
  • droplets leaving the nozzle form drops track according to the air jet profile of the assisted airflow created by the fan on the machine, but only the leaves on the droplet trajectory are exposed to the pesticide. In this case, the under surface of the leaves is not exposed to the pesticide. Due to the pesticide drifting away from fruit trees and inadequate machine efficiency, more pesticides are always sprayed than necessary.
  • One of the most effective methods for producing lower pesticide consumption than traditional pesticide spraying methods on turbo atomizers is the electrostatic charging of spray droplets to be delivered to the target. Electrostatic forces on the spray droplets create an electrical attraction between these droplets and the plant. This electrical attraction not only increases the ratio of droplets reaching on the plant but the pesticides also reach the under surface of the leaves, allowing control of the pests and diseases on the under leaf surfaces.
  • Turbo atomizers are widely used in the application of pesticides to orchards and vineyards.
  • the liquid pesticide droplets are produced by the pressure provided by a pump in the hydraulic nozzles and the resulting droplets are carried to the tree with the airflow provided by an axial fan on the sprayer.
  • Turbo atomizers only a small part of the total spray amount deposits on the target, while the rest is a chemical that causes plenty of environmental problems.
  • turbo atomizers especially the skirts of the tree crown are exposed to more pesticides, while the upper parts of the tree crown and the inner parts of the tree crown are exposed to fewer pesticides. This is considered as an undesirable pesticide distribution.
  • FIG. 1 A new unit that charges droplets with electrostatic in the application of pesticides with turbo atomizers Figure 2. Isometric view of a fan housing of the invention
  • FIG. 6 Front view of the electrostatic charging unit of the invention Figure 7. Side partial section a-a view of the electrostatic charging unit
  • the present invention charges droplets produced by standard type turbo atomizers used in fruit trees and vine with static electricity.
  • an electrical attraction field is formed between the static electrically charged droplets and the tree parts.
  • G gravitational force
  • a ring-shaped electrostatic electrode (10) located at the tip of the nozzle is placed on the existing nozzle to charge the droplets with static electricity.
  • This invention consists of parts of fan housing (1), electrostatic charging unit (2), fan protection cage (3), fan air director (4), fan (5), spray liquid tube (6), spray liquid tube inlet (7), static charging cage (8), air holes surrounding the electrode (9), electrostatic electrode (10), high voltage cable (11 ), spray fluid inlet (12), spray nozzle body (13), nozzle orifice (14), high-speed air duct (15) high-speed air duct through static charging cage.
  • the unit which charges the droplets with static electricity, is placed on the nozzle body (13) located on the back part of the turbo atomizer, this unit charges the droplets exiting from the nozzles by induction charging.
  • the high voltage used in the charging operation is provided from a DC source providing voltage from the battery on the tractor.
  • the droplets from each nozzle on the atomizer are charged with a ring electrode (10) made of nickel and its base is designed as a frustum of a cone.
  • the connection form of the charging electrode (10) to be used in electrostatic charging on the nozzle is provided in Figure 5.
  • Air venture cage (8) provides high-speed air flow over the ring electrode (10) through the holes ( 9) in a cage (8) surrounding the electrode (10) in order to prevent the droplets which are sprayed and opposite to the ring electrode (10) from sticking to the ring electrode (10).
  • the 12 V DC current taken from the tractor battery is primarily supplied to a high voltage source, the resulting high voltage is transmitted by the High Voltage Cable (11 ) to the electrostatic electrode (10) surrounding the nozzle body of the turbo atomizer (13).
  • the Electrostatic Electrode (10) is contained in a venturi-shaped static charging cage (8) and a base which has a frustum of a cone shape which allowed to air to pass in high-speed through the Holes surrounding the electrode (9).
  • the electrostatic electrode (10) charge the liquid droplets formed in the nozzle body (13) with the opposite charge, allowing the droplets to be charged, thereby also causing an opposite charge in the plant.
  • the charged droplets would be attracted by opposing charged plants.
