    • A spreader for a harvesting machine (10) includes a pair of counter-rotating spreader units (18, 20) each having an impeller (26, 28, 64, 66, 104) and a fan (38, 40, 76, 78, 106) supported on a common shaft. A plenum (50, 80) routes at least part of the airflow from a first fan to merge with chaff exiting the opposite impeller and at least a part of the airflow from the opposite fan to merge with chaff exiting the impeller on the machine side of the first fan. In one embodiment all airflow from a fan is ducted (52, 54) to an impeller on the opposite side, while a second embodiment commingles airflow from both fans in a plenum (80) from which portions of the mixed airflows is directed to the chaff exiting each impeller exit. In a third, embodiment an established airflow receives chaff from the impeller (104) on the side on which that airflow is generated.
    • 收割机(10)的撒布机包括一对反转吊架单元(18,20),每个具有叶轮(26,28,64,66,104)和风扇(38,40,76,78) 106)支撑在共同的轴上。 气室(50,80)将来自第一风扇的气流的至少一部分路由到离开相对叶轮的叶片和来自相对风扇的至少一部分气流与来自机器侧的叶轮离开的叶片合并 第一个粉丝 在一个实施例中,来自风扇的所有气流被导管(52,54)到相对侧的叶轮,而第二实施例在来自两个风扇的气室(80)中混合气流,从气室(80)将混合空气流的一部分引导到谷壳 离开每个叶轮出口。 在第三个实施例中,已建立的气流在从其上产生气流的一侧的叶轮(104)接收谷壳。
