BAUER RAINSTAR series

4 DESCRIPTION
The RAINSTAR is a universal irrigation machine for varying lengths and widths of fields and best suited for
irrigating seedbed and garden crops, park areas and horticultural plantations as well as any kind of grassland.
The main components of the RAINSTAR are a two-wheel undercarriage on which is mounted the turntable
swivelling through 270°, and the reel with the special PE-pipe, the multifunctional compact gearbox with
TX20 turbine, and the high-rise cart that is ideal particularly for high crops, with the BAUER wide-range gun.
The material of the PE-pipe corresponds to the latest findings of the art. One end of the pipe connects to the reel
drum and to the water supply through its axle. The other end of the pipe is coupled with the high-rise cart. The
cart’s track width is infinitely adjustable (See Technical Data).
The heart of the RAINSTAR is the TX 20 turbine. It is a full-flow turbine mounted in a flow-promoting position
directly on the reel. This turbine is nearly insensitive to soiled water and offers maximum efficiency. The drive
shaft is made of stainless steel. The regulating cam inside the turbine is coated with a wear-proof rubber lining.
The lifetime lubricated drive shaft bearing is sealed by a maintenance-free mechanical seal.
TX 20 turbine is designed for water flow rates from 13 to over 60 m³/h and features a wide control range. Impeller
speeds range from 200 to 800 rpm.
The cart retraction speed is infinitely variable. It is adjusted by means of the ECOSTAR 4300 and can be read
from the display. Depending on the available water flow and connecting pressure, it may vary between 8 and
150 m/h. The connecting pressure at the machine should not exceed 11 bar.
Power is directly transmitted from the turbine to the change-speed gearbox and the chain drive onto the reel. A
band brake prevents fast reverse rotation of the reel in the final shut-off position, when the PE-pipe is stretched.
The band brake as well as the gear wheels in the oil-filled change-speed gearbox act like a brake and prevent the
PE-pipe windings on the reel from loosening during pipe pull-off.
For safety reasons the drive is fitted with an emergency stop and a reversing stop as well. With this emergency
stop device the drive can be stopped immediately by hand.
Never remove the drive cover before you have turned off the water supply to the
machine and slackened the stretched PE-pipe.
To slacken the stretched PE-pipe move the gear shift lever downward carefully (see proper procedure).
A winding carriage moved by a helically grooved spindle ensures that the PE-pipe is wound up properly on all
layers.
