Abstract

A sorting cylinder for seeds and other grains with a horizontal, driven calibrating cylinder (11) resting on rolls (22, 23, 24, 25) and with a stationary machine casing (1) surrounding the calibrating cylinder (11) which has an inlet (4) for the material to be sorted and a mechanism (5, 6, 7) to lead off the fractions as well as a detachable longitudinal side wall (41, 42). In order to simplify storage and to facilitate the exchangeability also for untrained operating personnel, the calibrating cylinder (11) freely rests on four supporting rolls (22, 23, 24, 25) and at least one of the four supporting rolls (24; 25) is designed as a driving wheel (25). The calibrating cylinder (11) can be freely lifted off towards the top or can be mounted and dismounted through a longitudinal side (41, 42) of the machine casing (1).
