16 unigreen5 BLOWER GROUPAll the atomisers have a high speed fan rotor. You must take great careand beware of the effects that this can provoke: such as the aspiration andprojection of foreign bodies which, although of a small size, can be verydangerous especially for the eyes and face.5.1 AXIAL BLOWER GROUP WITH PULLEYThe atomisers that have a drive transmission between the pump and fan withpulleys are equipped with a neutral gear; the multiplied ratio is 1:4.26, therotation speed of the fan is 2,300 RPM.You should periodically check the tension of the belts; if they become too slackyou 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 thefigure to the side to move the base and tension the belts (FIG. 18)5.2 AXIAL BLOWER GROUP WITH MULTIPLIERThe transmission of the drive from the pump to the fan is done through amultiplier with one or two neutral gears.Normally the rotation speed of the fan is 1950 RPM in first gear and 2500 RPMin second in the multiplier with 2 gear ratios (multiplied ratios 1:3.6 - 1:4.6) and2,500 RPM in the multiplier with one gear ratio (1:4.6)with the power-takeoffrunning at 540 RPM.You can change from one gear to the next with the lever on the multiplier, madeaccessible through the opening on the side in the rear left part of the machine orat a distance on the right side. The lever has 2 or 3 positions depending on thenumber of gears and the central position is neutral (to use only the pumpwithout the fan).There are two models of blower groups with rear suction:- Axial blower (FIG19A): used for treatments similar to traditional multiplierblower groups, with delivery of the air in a circular crown.- Tangential blower: for use in small and medium espalier rows of vines. Thereare pulley drive versions or multiplier versions, adjustable jets can be mountedto spray the vegetation at various heights.WARNING: the gear change lever must only be used with the power-takeoffdisengaged and the fan stopped. If it is difficult to engage, turn the cardan shaftslightly by hand to find the right position of the lever (make sure the tractor isturned off).There are two deflectors (one on the right and one on the left) in the bottom partof 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 thesystem 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 inmachines with a multiplier, vice versa in those with a pulley (as the fan turns inthe opposite direction).For the maintenance of the multiplier (see point 8.2.3 Multiplier Lubrication).FIG. 19BFIG. 17FIG. 18Speed changeleverBelt tensioningsystemBelt tensioningsystemFIG. 19A |
