APPARATUS FOR SORTING OF ROUND ARTICLES Russian patent published in 2007 - IPC B07B1/10 B07B13/04 

FIELD: technique for sorting of round articles such as potatoes.

SUBSTANCE: apparatus has feeding hopper, device for feeding and discharging of articles to be sorted out, two conveyors arranged at an angle to horizontal plane in transverse-vertical plane, one under another, so as to define sorting-out slot extending transverse to course of advancement of articles under sorting-out process. Transverse axis of lower conveyor is arranged at an angle of 17-20 deg and connected to shaft of upper conveyor through flexible pin. Upper conveyor is positioned so that angles of inclination of its longitudinal and transverse axes relative to horizontal plane may be adjusted, and consists of individual belts. Edge of first belt closest to feeding hopper is spaced by distance at least equal to average width of large-fraction tuber horizontally enlarged by 10 mm from edge of lower conveyor in transverse-vertical plane. Each following belt is separated from other edge of previous belt by a distance at least equal to average length of tuber of respective fraction enlarged by 10 mm, and edge of subsequent belt does not extend beyond second edge of lower conveyor. Immovable strips positioned on lower conveyor, under each belt of upper conveyor, have lower edges which are extending in transverse-vertical plane at a distance equal to half the average value of tuber of respective fractions under sorting process from edge of projections of upper conveyor belts onto lower conveyor facing feeding hopper.

EFFECT: increased precision of sorting process.
