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).
