A disc for use in a disc screen is disclosed. The auger disc includes a central longitudinal disc axis and a hub extending a length along the longitudinal disc axis. The longitudinal disc axis is coaxial with the center of the hub. The hub further includes a hub surface and a helical ridge structure extending away from the hub surface and twisting about the longitudinal axis at least 360 degrees. The auger disc has a disc rotation axis that is parallel to the central longitudinal axis and is offset from the center of the hub. The auger disc is constructed to rotate about the disc rotation axis.

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).

A roller brush bed and a fluid delivery system are provided. The fluid deliver system includes a fluid source, a fluid supply tube connected to the fluid source, a movable fluid delivery bar in fluid communication with the fluid supply tube and a drive system attached to the movable fluid delivery bar and configured to move the movable fluid delivery bar relative to the at least one roller brush and along the roller brush bed, wherein the movable fluid delivery bar is configured to spray fluid toward the at least one roller brush as the movable fluid delivery bar is moved along the roller brush bed.

A disc for use in a disc screen is disclosed. The disc includes a longitudinal disc axis and a hub extending a length along the longitudinal disc axis. The hub further includes a hub surface and a helical ridge structure extending away from the hub surface and twisting about the longitudinal axis at least 360 degrees. A cross-section of the hub taken perpendicular to the longitudinal disc axis is non-circular.

A grizzly apparatus includes a plurality of grizzly bars arranged at predetermined intervals in a second direction perpendicular to a first direction which is an extension direction of center axes of the grizzly bars. Each of the plurality of grizzly bars is rotatable in a direction opposite to a direction of rotation of its adjacent grizzly bar so that a slit through which a screening target object passes and a gap through which the screening target object does not pass alternately emerge, between adjacent grizzly bars. The guide includes an outer member forming its outer shape, and has at least one guide surface inclined with respect to the second direction in such a way that the guide surface descends as the guide surface advances in the second direction toward the slit to guide the screening target object having fallen onto the guide to the slit.
