HIGH-SPEED ROTARY SCREW DEVICE FOR SEPARATION OF TUBEROUS ROOTS INTO FRACTIONS Russian patent published in 2013 - IPC A01D33/08 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry, in particular, to devices for separation of tuberous roots into fractions by size criteria. The device comprises a cylindrical drum and a drive mechanism. The drum has a surface which consists of a flexible tube. The flexible tube is wound helically on the rods with a variable pitch. Inside the drum the fixed tuberous root guider is placed. The tuberous root guider consists of an elastic plated splitter and a chute grate. The splitter is mounted on the rod which is mounted with the ends on the radial telescopic racks on the fixed axis of the drum and on the stub. The stub is suspended on the frame through the cylindrical rings provided with locking bolts. The chute grate consists of individual plates. The plates are inclined towards the axial movement of the material and fixed on the other rod. The ends of the rod also rest by the cylindrical rings equipped with locking bolts on the fixed axis of the drum and the stub suspended on the frame.

EFFECT: invention provides movement of the processed material in the axial direction inside the high-speed drum.
