  • Patent number: 5624315
    Abstract: A combine harvester (1) is provided with a grain cleaning mechanism (12), comprising a fan (33) installed in a generally volute-shaped fan housing (72), having primary air inlets (73) in its side walls and a secondary air inlet (74) in its top wall. The housing (72) further has a main outlet duct (80) directed to a chaffer sieve (31) and a lower grain sieve (32) and an additional outlet duct (81) directed to a pre-cleaning sieve (29) and an associated grain pan (30). The secondary air inlet (74) is covered with a plurality of juxtaposed plates (75), comprising sets of louvres (76) which are opened rearwardly. Grain kernels which unwantedly fall off the leading edges of the sieves (29, 31, 32) or the grain pan (30) and into the outlet duct (80, 81), may be engaged and thrown upwardly by the blades (95) of the fan (33), but will be returned into the fan housing (72) by the louvres (76), which nevertheless do not obstruct an efficient air intake by the fan (33) .
