Abstract
An agricultural harvester includes a chassis; a cleaning system carried by the chassis and is configured to clean crop material; and a crop material elevator carried by the chassis that is supplied with cleaned crop material from the cleaning system. The crop material elevator includes: a housing including a boot portion at a bottom of the housing, the boot portion defining a bulbous shape on at least a conveyance side of the housing; a driving loop held within the housing and configured to rotate; a driving element linked to the driving loop and configured to rotate the driving loop; and a plurality of paddles carried by the driving loop.
Claims20
An agricultural harvester, comprising:
- a chassis;
- a cleaning system carried by said chassis and configured to clean crop material;
- and
- a crop material elevator carried by said chassis and supplied with cleaned crop material from said cleaning system, said crop material elevator including:
- a housing including a boot portion at a bottom of said housing, said boot portion defining a bulbous shape on at least a conveyance side of said housing;
- a driving loop held within said housing and configured to rotate;
- a driving element linked to said driving loop and configured to rotate said driving loop;
- and
- a plurality of paddles carried by said driving loop.
A crop material elevator, comprising:
- a housing including a boot portion at a bottom of said housing, said boot portion defining a bulbous shape on at least one side of said housing;
- a driving loop held within said housing and configured to rotate;
- a driving element linked to said driving loop and configured to rotate said driving loop;
- and
- a plurality of paddles carried by said driving loop.
An agricultural harvester, comprising:
- a chassis;
- a cleaning system carried by said chassis and configured to clean crop material;
- and
- a crop material elevator carried by said chassis and supplied with cleaned crop material from said cleaning system, said crop material elevator including:
- a driving loop configured to rotate;
- a driving element linked to said driving loop and configured to rotate said driving loop;
- a plurality of paddles carried by said driving loop, said plurality of paddles each being carried by said driving loop to define a travel path with a rotational component that transitions into a linear component;
- and
- a housing at least partially surrounding said driving loop and said plurality of paddles, said housing having a region of divergence relative to said driving loop adjacent to said rotational component of said travel path and a region of convergence relative to said driving loop adjacent to said linear component of said travel path.
