ABSTRACT:
A sieve for a thresher, especially a combine-harvester, for the separation of grain-like field fruits from stalk-like and chaff-like components has channels (2, 2a, 2b) extending parallel to a longitudinal axis (1). The channels (2, 2a, 2b) are open to a first side A, from which they are loaded. The channels (2, 2a, 2b) are delimited by a bottom3and laterally following flanks (4, 5) which include openings (9). Air guide following channels (10, 11) are open to a second side B, which face away from the first side A. The two air guide channels (10, 11) are arranged in a direction transverse to the longitudinal axis (1) and are separated by a continuous separation wall (13). The separation wall (13) extends between two neighbouring channels (2, 2a) which extend parallel to the longitudinal axis (1). In these separated air guide channels (10, 11), respectively, the openings (9) of only one of the two channels (2, 2a) separated by the air guide channels (10, 11) are open.
