Abstract
An agricultural harvesting machine includes a tailings conveyor housing. The agricultural harvesting machine provides a cleaning device for cleaning threshed and separated grain. The tailings conveyor housing collects tailings from the cleaning device and propels the tailings with a first impeller against a first rethreshing member and radially to a second impeller. The second impeller propels the tailings against a second rethreshing member and radially to a conduit in the tailings conveyer housing, where the tailings are redirected back to the cleaning device and spread out over the cleaning device.
Claims23
A tailings conveyor comprising:
- a tailings conveyor housing;
- a first opening in the tailings conveyor housing;
- a first impeller in the tailings conveyor housing adjacent the first opening, whereby tailings are delivered through the first opening to the first impeller;
- a second impeller in the tailings conveyor housing positioned radially from the first impeller, whereby the tailings are propelled radially from the first impeller to the second impeller;
- a second opening in the tailings conveyor housing positioned radially adjacent to the second impeller, whereby the tailings are propelled radially from the second impeller through the second opening;
- and
- a conduit extending from the second opening, whereby the tailings are propelled radially from the second impeller directly to the conduit via the second opening.
An agricultural harvesting machine comprising:
- a chassis;
- a means mounted on the chassis for feeding crop material thereto;
- a threshing, separating, and cleaning means mounted on the chassis for threshing and separating grain from the crop material, for cleaning threshed and separated grain and for separating tailings from the clean grain;
- a tailings conveyor housing mounted on the chassis;
- a first opening in the tailings conveyor housing;
- a first impeller in the tailings conveyor housing adjacent the first opening, whereby the tailings are delivered through the first opening to the first impeller;
- a second impeller in the tailings conveyor housing positioned radially from the first impeller, whereby the tailings are propelled radially from the first impeller to the second impeller;
- a second opening in the tailings conveyor housing positioned radially adjacent to the second impeller, whereby tailings are propelled radially from the second impeller through the second opening;
- and
- a conduit extending from the second opening, whereby the tailings are propelled radially from the second impeller directly to the conduit via the second opening.
A method for conveying tailings in an agricultural harvesting machine comprising:
- providing a chassis;
- mounting a tailings conveyor housing on the chassis;
- providing a first opening in the tailings conveyor housing;
- providing a first impeller in the tailings conveyor housing adjacent the first opening;
- delivering tailings through the first opening to the first impeller;
- positioning a second impeller in the tailings conveyor housing radially from the first impeller;
- propelling the tailings radially from the first impeller to the second impeller;
- positioning a second opening radially adjacent to the second impeller;
- propelling the tailings from the second impeller radially through the second opening;
- extending a conduit from the second opening;
- and
- propelling the tailings radially from the second impeller directly to the conduit via the second opening.
