Abstract
A harvester that includes an elevator, a spreader conveyor and a secondary extractor. The elevator includes a lower proximal end that receives harvested material and a higher distal end that dispenses the harvested material. The spreader conveyor includes a proximal end that receives the harvested material from the elevator and a distal end that dispenses the harvested material. The secondary extractor includes an inlet and an outlet, where it extracts debris from the harvested material dispensed from the distal end of the spreader conveyor into the inlet and expels the debris out of the outlet. The spreader conveyor can include a spreader belt that rotates in an endless loop, where the harvested material received from the elevator spreads out on the spreader belt. An extractor fan can create air flow to pull debris through the secondary extractor. The spreader conveyor can throw harvested material into the air flow.
