摘要：
The invention relates to a cleaning device (2) for cleaning crops comprising a roller bed (4) comprising several rollers (3) rotatable about a rotational axis (3a), whereby gaps (10) are or can be provided between said rollers (3) in such a manner that impurities present together with the crop on an upper side (4a) of the roller bed (4) can be discharged through the gaps (10) while, at the same time, the crop can be kept on the upper side (4a), whereby the rollers (3) of the roller bed (4) can be driven in such a way that the impurities can be discharged through the gaps (10).According to the invention, tappets (6) movable in the direction of conveyance (F) are arranged above the upper side (4a) of the roller bed (4) in such a way that crop present on the upper side (4a) of the roller bed (4) can be carried along by these tappets (6) in the direction of conveyance (F), whereby, to that end, said tappets (6) extend between at least two driver means (8； 12), whereby at least the tappets (6) arranged above said upper side (4a) of said roller bed can be moved by the at least two driver means (8； 12) in the direction of conveyance (F).
