5BLOWER GROUP

All the atomisers have a high speed fan rotor. You must take great care and beware of the effects that this can provoke: such as the aspiration and projection of foreign bodies which, although of a small size, can be very dangerous especially for the eyes and face.

5.1AXIAL BLOWER GROUP WITH PULLEY

The atomisers that have a drive transmission between the pump and fan with pulleys are equipped with a neutral gear; the multiplied ratio is 1:4.26, the rotation speed of the fan is 2,300 RPM.

You should periodically check the tension of the belts; if they become too slack you should tension them again.

To do this for the models equipped with a specific system belt tensioning sys- tem, use the screw indicated to the side ( FIG. 17).

For all the other models use an adjustable wrench on the nut indicated in the figure to the side to move the base and tension the belts (FIG. 18)

5.2AXIAL BLOWER GROUP WITH MULTIPLIER

The transmission of the drive from the pump to the fan is done through a multiplier with one or two neutral gears.

Normally the rotation speed of the fan is 1950 RPM in first gear and 2500 RPM in second in the multiplier with 2 gear ratios (multiplied ratios 1:3.6 - 1:4.6) and 2,500 RPM in the multiplier with one gear ratio (1:4.6)with the power-takeoff running at 540 RPM.

You can change from one gear to the next with the lever on the multiplier, made accessible through the opening on the side in the rear left part of the machine or at a distance on the right side. The lever has 2 or 3 positions depending on the number of gears and the central position is neutral (to use only the pump without the fan).

There are two models of blower groups with rear suction:

-Axial blower (FIG19A): used for treatments similar to traditional multiplier blower groups, with delivery of the air in a circular crown.

-Tangential blower: for use in small and medium espalier rows of vines. There are pulley drive versions or multiplier versions, adjustable jets can be mounted to spray the vegetation at various heights.

WARNING: the gear change lever must only be used with the power-takeoff disengaged and the fan stopped. If it is difficult to engage, turn the cardan shaft slightly by hand to find the right position of the lever (make sure the tractor is turned off).

There are two deflectors (one on the right and one on the left) in the bottom part of the delivery outlet of the fan groups which define the direction of the airflow; lower if the deflector is lowered and higher if the deflector is raised. For the system to work properly it should be set up as follows: the left deflector (looking at the atomiser from behind) raised and the right one lowered in machines with a multiplier, vice versa in those with a pulley (as the fan turns in the opposite direction).

For the maintenance of the multiplier (see point 8.2.3 Multiplier Lubrication).

AP APC, DEVIL, serie EOLO, EXPO, SIRIO specifications

Unigreen is recognized for its innovative agricultural machinery, particularly in the realm of spraying technology. Among its flagship products are the SIRIO, EXPO, DEVIL, AP APC, and the EOLO series, each designed to cater to the diverse needs of modern-day farming.

The SIRIO line is particularly lauded for its versatility and efficiency. This series is engineered for precision application, equipped with advanced GPS technology that allows for automatic section control. The ability to adjust spray patterns and flow rates in real-time ensures minimal waste and optimal coverage, which translates to both economic and environmental benefits. Its durable construction also promises longevity, making it a reliable choice for farmers looking for investment-worthy equipment.

The EXPO series is tailored for open-field spraying. It boasts an impressive working width and can cover large areas quickly. The EXPO's multifunctional design includes a user-friendly interface, allowing operators to monitor and adjust performance easily. This model emphasizes user comfort and safety, featuring advanced anti-drip systems to minimize environmental impact during operation.

Next, the DEVIL is particularly noteworthy for its compact design and agility. Ideal for vineyards and orchards, the DEVIL allows for precise application in constrained spaces, facilitating detailed and targeted treatments. Its lightweight build ensures easy maneuverability without sacrificing power, and the robust motor guarantees consistent performance.

The AP APC series stands out for its multi-purpose functionality. This range is designed to perform well under diverse environmental conditions, making it suitable for various crops. The addition of a high-capacity tank allows for extended working hours without frequent refills, enhancing productivity. Furthermore, its low-center-of-gravity design improves stability on uneven terrains.

Lastly, the EOLO series showcases Unigreen's commitment to eco-friendliness. These machines feature low-drift nozzles that keep the chemicals where they are needed most, which helps in minimizing off-target application. The EOLO series also incorporates energy-efficient technologies, reducing fuel consumption and greenhouse gas emissions.

In summary, Unigreen's SIRIO, EXPO, DEVIL, AP APC, and EOLO series represent a blend of innovation, efficiency, and environmental responsibility. Each model is designed to meet the specific requirements of various agricultural environments, ensuring that farmers can operate at peak efficiency while contributing to sustainable farming practices.
