screw, feeding transporter, creasing rollers, quantity of root tubers let through the device.

This article contains the results of the experimental research on the quantity of root tubers let through to the creasing rollers through the clearance between the worm screw and the feeding transporter working branch in the combined root crop cleaner. It also describes the experimental set and the technique used for dummy tuber root transportation research, with the size of root tubers 0.05; 0.1; 0.15 and 0.2 m in diameter. The experimental research has been held basing on the PFE 2⁴ type planned experiment realisation. The variable factors were transporter speed (variation extremes of 1.2…1.8 m/s), worm pitch (variation extremes of 0.5…0.7 m), clearance gap between the worm screw and transporter (variation extremes of 0.05…0.1m), worm screw angle speed (variation extremes of 7…15 rad/s). The work provides the regression equations that characterize the dependency of the amount or tubers being let through the worm screw to the creasing rollers from the size characteristics of fodder beet root tubers. A graphic dependency analysis has been held and it set the root crop cleaner parameter and work modes best for the maximum quantity of root tubers ran through the device.
