4.1 Function
This is a self-propelled working machine for picking up, cleaning and loading of sugar
beet from piles at the side of the field.
The sugar beet is picked up via a roller system. The first roller, the pickup roller, works
several centimetres into the ground, picks up the sugar beet and lifts it over a cleaning
roller onto three conveyor rollers. The conveyor rollers transport the beet outward. The
conveyor rollers have carriers attached to them. These preclean the sugar beet and
convey it to four counter-rotating pinch rollers positioned behind them. The front and
rear rollers may be individually adjusted in their speed. The direction of rotation of the
rollers is reversible. Operating disturbances due to jammed stones are generally auto-
matically detected and remedied by the machine.
If needed, the last sugar beet may be pulled onto the pickup rollers using the residual
beet pickup controlled via the left joystick in the driver's cabin. No manual assistance
is required.
The main cleaning action is performed on the rollers at the front of the machine. The
counter-rotating rollers pull out soil, weeds and other impurities. Depending on equip-
ment options, further cleaning is then performed using a sieve conveyor or a roller
cleaner which transport the sugar beet to the truck conveyor. The truck conveyor
loads the sugar beets onto the transport vehicle (truck).
All computers are networked via a CAN bus and supply all information to the driver
on the large R-Touch colour terminals. All functions of the machine are controlled and
monitored by a single person from the driver's cabin.
