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 bottom 3 and 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.

Abstract: A combine-harvester for harvesting grains has a zigzag arrangement and is formed from repeating portions (13, 13a, 13b, 13c) which each portion includes a profile (14, 14a, 14b, 14c). Each profile has a first leg (16), which is arranged at an angle to a second leg (18). The first leg (16) is provided with an extension (22). The extension is arranged parallel to the first leg (16) in a transverse direction to the conveying direction (6) and ends at an edge. The extension (22) projects in conveying direction (6) beyond the connection area (19) of the first leg (16) with the second leg (18). The extension is arranged ahead of the second leg (18) in the conveying direction (6). Stems (27), which possibly fall onto the sieve surface, are carried by the extensions (22). As a result of the movement of the sieve as it is moved in the conveying direction (6), the stems fall off the sieve surface (5).

Abstract: An assembly has a mowing finger 1 with a bottom part 4, a top part 5 and a blade gap 8 between the two. The cutter 3 rests on a support 6 of the bottom part 4. The cutter 3 is arranged in the blade gap 8 and is able to move to and fro. A holding-down element 14 is form-fittingly held at the top part 5 in the direction of movement of the cutter 3. The top part 5 projects into an aperture in the holding-down element 14. Via its supporting portion 15, the holding-down element 14 is supported under pre-tension against the blade 7 and holds the blade 7 relative to the support 6. The rear attaching ends 10, 11 of the bottom part 4 and of the top part 5, as well as the fixing portion 16 of the holding down-element 14, are jointly secured to the back bar 2 by a fixing bolt 13. Accordingly, the fixing conditions are simplified. Further, by being form-fittingly held, the holding-down element 14 is securely prevented against displacement relative to the top part 5.
