Combine harvester with a tangentially arranged threshing

The present invention relates to a combine harvester (1) having a tangentially arranged threshing device (2) comprising at least one threshing drum (7) and at least one with reference to the threshing drum (7) variable spacing separator concave (14), and with one of the threshing device (2 ) downstream, a feed drum (13) and two separating rotors (10) comprising Axialabscheidevorrichtung that extending an (at least over the width of the separation rotors 10) lead-in area (11), to the (at least one separator concave (14) of the threshing 2) adjacent, starting from the separator concave in the transition region (14) to the inlet region (11) extending substantially in the longitudinal direction of the combine harvester (1) extending guide member (19, 26) is arranged, which is communicating with the separator concave (14) into engagement which distance (B) to the threshing drum (7) at a change of the distance (a) to the separator (14) to the threshing drum (7) konstan t remains.
