Cleaning means for an agricultural harvesting machine
摘要：
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 under an angle (α). 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).
摘要（中）：

联合收割机（1）设置有谷物清洁机构（12），其包括安装在大致涡形风扇壳体（72）中的风扇（33），在其侧壁中具有一次空气入口（73）和次级 空气入口（74）在其顶壁。 外壳（72）还具有一个主出口导管（80），该主出口导管（80）指向一个切碎筛（31）和一个下颗粒筛（32）和另一出口导管（81），引导到预清洁筛（29） （30）。 二次空气入口（74）被多个并置的板（75）覆盖，所述多个平行板（75）包括在角度（α）下向后打开的一组百叶窗（76）。 不必要地从筛子（29,31,32）或谷物盘（30）的前边缘落下并进入出口管道（80,81）中的谷粒可被叶片（95）向上接合并向上抛出 风扇（33），但是将被百叶窗（76）返回到风扇壳体（72）中，但是风扇（33）不会妨碍有效的空气进入。
