Abstract
A debris removal system for an agricultural harvester can include an extractor housing defining a housing inlet, a housing outlet, and a passage. The extractor housing can further define an airflow channel for directing debris through the extractor housing from the housing inlet to the housing outlet. An airflow device can be configured to generate an airflow from the housing inlet towards the airflow device. The airflow can be configured to separate the debris billets of a crop material. A drum can be positioned at least partially within the airflow channel and between the housing inlet and the passage. The debris within the airflow channel can be directed by the drum toward the housing outlet.
Claims18
A debris removal system for an agricultural harvester, the debris removal system comprising:
- an extractor housing defining a housing inlet, a housing outlet, and a passage, the extractor housing further defining an airflow channel for directing debris through the extractor housing from the housing inlet to the housing outlet;
- an airflow device that generates an airflow from the housing inlet towards the airflow device, wherein the airflow separates the debris from billets of a crop material;
- and
- a drum positioned at least partially within the airflow channel, the drum positioned between the housing inlet and the passage, wherein the debris within the airflow channel is directed by the drum towards the housing outlet, and wherein a portion of the drum extends through the housing outlet.
A method for operating a debris removal system for an agricultural harvester, the agricultural harvester including a material processing system that receives a flow of harvested materials, the method comprising:
- generating, with an airflow device, an airflow through a channel defined by an extractor housing from a housing inlet defined by the extractor housing to a passage defined by the extractor housing;
- rotating, with a motor, a drum positioned at least partially within the extractor housing;
- moving, with a drum actuator, the drum vertically between a first position and a second position relative to the housing;
- and
- directing, with the drum, debris from the housing inlet to a housing outlet defined by the housing.
