DEVICE FOR SEPARATION OF TUBEROUS ROOTS AT ROTORY CUP-TYPE FRACTION Russian patent published in 2012 - IPC A01D33/08 A01D17/02 A01D17/04 

FIELD: agriculture.

SUBSTANCE: this device includes hoisting mechanism, mesh sorting tools, and its driving gear, as well as cone sorting tools mounted on vertical shaft. The shaft is vertical to a pivot pin of the bladed cylindrical hoisting drum, herewith tool base circumferences intercross with circumference of an open drum inlet. Upper tool inlet is of inverted truncated cone form with removable micromesh wall. Whereas, minor cone base is attached to the upper shaft end by wheel hubs and balance arms for free screening of no-go tuberous root fraction. Cylinder guide neck adjoins to a minor cone base rim. Base down cone with removable coarse mesh wall is mounted under truncated cone at the shaft. Fixed semicylindrical housing is mounted above a cone base edge; this housing passes into a discharge chute raised boss, one end of which is located on a semi-circumference of cone rotation plane, and its free minor end is tilted to a degree of root rolling. There is a fixed cone collector for medium size roots located under the cone base with the discharge chute under it.

EFFECT: increase in productivity and reliability.
