4.7.5 NOZZLES :
They have a lot of importance for chemical distribution on the soil that has to be treated. If
they are wear the distribution of the product could be not uniform .
They are of different types and sizes depending on the particular use (droplet size or
pressure).
Improper use gives rise to ineffective treatments.
"FAN" type in example can work with pressures 1-16 bar and it generates medium- large
droplets. It is made of: plastic, brass, ceramic, stainless steel.
It
’s recommended for weed control of pre-emergence and post-emergence.
The "CONE" type can work with pressures from 1-16 bar and generates drops of small
size. Typically is made of ceramic and is composed of two pieces: the nozzle and the
slinger, and it
’s recommended for very dense vegetation.
There is also a
“mirror” type recommended for liquid fertilizer.
Useful tips for the distribution of product
Here are some rules to follow in order to make a correct and uniform distribution of the
product on the vegetation to be treated.
The nozzles have an important role in this operation: they must be well cleaned and
oriented in a correct manner on the ground .
Do not forget to check that both filter pressure and suction are free of impurities.
Verify that the speed and the working pressure are appropriates and that the total flow rate
of the nozzles is lower of 20-25% than the flow rate of the pump.
Properly adjust the height of the boom at about 50-60 cm from the culture.
4.7.6 FOAM MARKER KIT:
It is assembled only on request.
It is very useful to highlight the portion of ground has already been treated.
Further explanations and clarifications can be found in the booklet enclosed with this
manual.
4.7.7 INTERROW BOOMS :
They are particularly suitable for weed control in orchards and are applied to a rear
mounted sprayer. They are equipped with a special joint that allows to keep the boom on
the right position even if it knocks against some obstacles.
Furthermore, the nozzles have a protection bell that avoid any contact between the leaves
and the chemical
.
4.7.8 VERTICAL BARS :
Are particularly suitable for crop-spraying on orchards or vineyards for high volume spray.
They are of two types: STRAIGHT or ARCHED.
4.7.8 HOSE REEL :
This component can contain up to 100 meters of hose and it is available only on
mechanical version.
4.7.9 LANCES:
They are different models: gun, knob , lever and mitra. Different kind of nozzles having
different flow rates are available.
Their use is easy but we suggested to follow these simples rules to avoid problems:
-do not lock the aperture lever cause , in the event of a fall, this would continue to release
the liquid making it uncontrollable.
-do not direct the flow directly on people or animals or to areas where there is electricity.
-Remember to depressurize it after pump switch off .
