5.4LIFTING

The lifting devices are very useful to adjust the height of the boom on the basis of the height of the vegetation to be treated.

The height of the boom is adjusted as follows:

=the hydraulic version has a double-effect cylinder controlled by a special parachute stop valve.

=to lift and lower the boom use the control on the elettroil pushbutton panel or the quick-fit couplings connected to the lifting cylinder.

=periodically lubricate the sliding guides with grease and check the guide bolts are tightened properly, with a suitable play.

5.5DISTRUBUTION WITH HERBICIDE BOOM

5.5.1 DESCRIPTION OF TYPE OF JETS

Various types of jets are fitted; with a single fixed (threaded or quick-fit) or with multiple heads.

Generally they have a non-drip diaphragm and are made out of reinforced plastic, suitable for pressures up to 15-20 bar, some models are nickel plated brass for pressures up to 40 bar. There are versions with 2-3-4 plastic nozzle heads and 2 brass heads.

5.5.2 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.

a) Fan nozzles

Available in various materials: plastic-brass-stainless steel-ceramic. They are used at pressures from 1-5 bar producing medium-large drops; particularly suitable for pre-emergency and post-emergency weeding. b) Conical nozzles

Generally made of ceramics, these nozzles consist of two parts; the actual nozzle and the slinger. They are particularly resistant to wear and designed to work from 1 to 16 bar producing a high density of small drops with a strong turbulence. This turbulence makes them suitable for penetrating luxuriant vegetation and so they are suitable for fungicides and insecticides. When necessary they can also support slightly higher pressures.

c) Anti-drift nozzles

There are various models of nozzles that make it possible to reduce the effect of drift.

d)Mirror nozzles for liquid fertilizers.

5.5.3 DISTRUBUTION

a)Check that all the nozzles are in a good condition and are positioned correctly on the boom. The automatic positioning with quick heads is done for threaded heads with the relevant adjustment wrench.

Check that the total capacity of the nozzles is at least 25% less than the capacity of the pump.

b)Make sure the suction and delivery filters, as well as the non-drip membranes are clean and in a good condition and that the same quantity of liquid is supplied along the entire width of the boom.

c)Check that the height of the boom from the crops is suitable for regular distribution. For a boom with fan nozzles fitted at 50 cm from each other; this height is roughly 50 cm.

d)Working pressure.

The working pressure must allow for the indications in points 5.5.2 and the following of this handbook and also allow for the speed of the tractor to obtain the desired spraying in litres/hectare.

To assess the data, consult tables N° 1-2.

These tables are valid for spaces between the nozzles of 50cm.

To meet particular requirements UNIGREEN can supply booms with different spaces between the nozzles and setups suitable for running at pressures over 20 bar.

CAMPO 11 - 16 - 22 - 32, DSP 11 - 16 - 22 - 32 specifications

Unigreen DSP Series and CAMPO Series are advanced agricultural sprayers designed to meet the evolving needs of modern farming. The Unigreen DSP (Dynamic Spraying Product) models 11, 16, 22, and 32, along with the CAMPO models of the same specifications, are engineered for efficiency, precision, and reliability in crop protection.

One of the key features of the Unigreen DSP models is their innovative spraying technology. Each model is equipped with a high-capacity tank that allows for extended operation without the need for frequent refills. The DSP series incorporates adjustable booms that provide precise application across various crop types. This ensures uniform coverage and minimizes waste, making it an environmentally friendly option for farmers.

The CAMPO series also boasts similar tank capacities and boom adjustments, making them suitable for diverse agricultural applications. Both series offer customizable options, allowing farmers to choose the configuration that best fits their land and crop requirements.

Another standout characteristic of both Unigreen and CAMPO sprayers is their user-friendly interface. Equipped with advanced electronic controls, farmers can easily monitor and adjust spray rates, pressure, and other critical parameters in real time. This technology not only enhances the sprayers' operational efficiency but also aids in achieving the optimum application rates for different pesticides and fertilizers.

Furthermore, both series integrate cutting-edge GPS technology, enabling precision agriculture practices. This feature allows operators to map their fields, ensuring that every inch is accurately treated, while also reducing the possibility of overlap or missed areas. This precision application reduces chemical usage and ultimately leads to cost savings.

Durability is another primary focus in the design of the Unigreen DSP and CAMPO sprayers. Built with high-quality materials that can withstand harsh environmental conditions, these sprayers promise longevity and consistent performance over time.

In summary, Unigreen DSP and CAMPO models 11, 16, 22, and 32 are technologically advanced agricultural sprayers that combine efficiency, precision, and durability. With features such as adjustable booms, advanced electronic controls, and GPS technology, they cater to the diverse needs of today’s farmers, helping to enhance productivity while minimizing environmental impact. These sprayers are positioned to play a pivotal role in the future of sustainable agriculture.
