Abstract
Trash removal apparatus in a sugar cane harvester comprises an axial flow extractor fan having multiple blades to draw trash out of harvested cane and to discharge it through a duct on the pressure side of the fan. The duct is in the form of a helical trash guide member which collects the trash out of the air flow and discharges the trash laterally. The diameter of the fan blades is chosen so as to leave a relatively large annular gap between their ends and the wall of the duct through which most of the trash passes thereby reducing power consumption by the fan.
