Abstract: An agricultural harvester includes: a chassis; a cleaning system carried by the chassis; a crop material elevator supplied with crop material that has passed through the cleaning system; and an auger supplying the crop material from the cleaning system to the crop material elevator. The auger includes: an auger axle configured to rotate and defining an auger axis of rotation; a first flighting having a first helical direction and configured to be rotated by the auger axle; a second flighting having a second helical direction opposite to the first helical direction, the second flighting configured to be rotated so as to direct crop material conveyed by the first flighting back toward the first flighting; and a thrower connected to the first flighting and the second flighting and configured to convey crop material transversely relative to the auger axis of rotation.

Abstract: An agricultural harvester includes a chassis; at least one ground engaging traction member connected to the chassis; a cleaning system held by the chassis and configured to clean crop material; and an elevator supplied with the crop material cleaned by the cleaning system. The elevator includes a housing having a crop material inlet that receives the crop material, a boot portion that forms a bottom of the housing, an air inlet and an air outlet; a plurality of paddles configured to convey the crop material through the housing and away from the boot portion in a generally vertical direction; and a blower configured to produce a pressurized air stream through the air inlet that expels loose crop material into the air outlet as the crop material is conveyed away from the boot portion.

Abstract: An agricultural harvesting system including a chassis, an agricultural product moving device coupled to the chassis, an airflow system, a cleaning system and an airflow characterizing system. The cleaning system is configured to receive the agricultural product from the moving device. The cleaning system is configured to receive an airflow from the airflow system. The airflow characterizing system is at least partially positioned in the airflow, and is configured to measure an airflow profile across the cleaning system. The airflow characterizing system includes a plurality of sensors that determine airflow by measuring a thermal transfer from the sensors to the airflow. The airflow characterizing system being configured to maintain a substantially constant electrical resistance of the sensors as the airflow varies. The airflow characteristics are measured in the cleaning system and are used to improve the cleaning capacity of the harvesting system.
