SPRAYING
WARNING: the indications to follow for using chemical products are indicated
in paragraph 2.2.1.
6.1
DESCRIPTION OF THE DIFFUSERS
The distributor accessories of the TurboTeuton range are equipped with
variable diffusers (FIG. 18) so you can direct the airflow (and consequently
the treatment) onto the vegetation to treat on the basis of your needs.
According to the configuration of the accessory the diffusers have outlet
mouths with different shapes and sections. The diffusers can be equipped
with a double series of non-drip jets on request (FIG. 19).
6.1
DESCRIPTION OF TYPE OF JETS
Various types of jets are fitted; with a single or double head.
Generally they have a non-drip diaphragm and are made out of brass,
suitable for pressures up to 40 bar, some models are nickel plated.
The jets can be equipped with different types of nozzles, changing the
locking ringnuts. The jets used normally have high volume, Ø18, ceramic
plates and low volume conical nozzles (Albuz ATR or Teejet TXB). The jets
for cannons have a jet holder with adjustable delivery and spray that has
high volume, ceramic plates, Ø15 instead of 18.
All the jets normally used have three positions (FIG. 21):
a)
spray - if the nozzle is pointing outwards, away from the blower group,
parallel with the non-drip valve
b)
closed - if the nozzle is at 90° with respect to the non-drip valve or, for
the single jet if it is facing inwards towards the blower group
c)
nozzle second spray - when these are pointing towards the outside of
the blower group parallel with the non-drip valve.
6.2
DESCRIPTION OF TYPE OF NOZZLES
The nozzles are extremely important to obtain a correct distribution on the
vegetation to be treated. Poor quality or worn nozzles have a tendency to
create unevenly treated strips.
The nozzles are produced in various sizes, to work with a precise pressure
range, to create certain types of larger or smaller drops; using nozzles for a
purpose they are not envisaged for prejudices the precision and duration of
the nozzles.
6.2.2 LOW VOLUME CONICAL NOZZLES (150-500L/HA)
Made of two ceramic pieces with colour-coded plastic inserts, they are
available in various sizes identified by the colour (see table 3 page 32).
They have been specifically designed to obtain a large number of small
drops with strong turbulence even at low pressures (2-3 bar). This turbulence
makes them suitable for penetrating luxuriant vegetation and so they are
suitable for fungicides and insecticides. The nozzles of the TR Lechler and
TXA Teejet series are in this category.
6.2.3 ANTI-DRIFT NOZZLES
Specific anti-drift nozzles are available from Unigreen. The main
characteristic of these nozzles is that they eliminate the fog effect caused by
the presence of drops that are too small and are particularly sensitive to
drifting. For further information please contact Unigreen for the relevant
instruction handbook.
