Abstract

A sorting machine for grained products comprises at least one sorting board which is inclined relative to horizontal and vertical planes and reciprocatingly vibratable in a plane and direction suitable for sorting, a unit for supplying a product to be sorted and arranged in one region of the sorting board and a unit for separating and withdrawing a sorted product and located in another region of the sorting board, the sorting board with the supplying unit and the separating and withdrawing unit together forming a sorting unit, two imbalance drives which operate in opposite directions and cooperate with the sorting unit for driving the latter in vibration, a base frame, a unit forming at least three supporting points on which the sorting unit is supported in a vibration-damping manner freely movably so as to provide inclination of the sorting unit relative to horizontal and vertical planes, and a unit for additionally adjusting the inclination relative to the horizontal and vertical planes.
