Abstract: A closing flap for a threshing or separating cage of a threshing and/or separating device. The threshing or separating cage can be provided with threshing or separating elements which are configured, in cooperation with a threshing cylinder or a separating rotor of the threshing and separating device, to thresh out or separate crop, and the threshed or separated grain can pass through passages provided in and/or between the threshing or separating elements and reach a cleaning system. The closing flap can be movable between a closed position, in which it at least partially closes a cavity arranged downstream of one or more of the passages, and an open position. On the side of the closing flap facing the cavity can be provided with structure for extracting crop which has collected in the cavity.
