Zusammenfassung: | An agricultural harvester (10) includes: a chassis (12); a cleaning system (26) carried by the chassis (12) and configured to clean crop material; and a crop material elevator (60) carried by the chassis (12) and supplied with cleaned crop material from the cleaning system (26). The crop material elevator (60) includes: a driving loop (84) configured to rotate; a driving element (86) linked to the driving loop (84) and configured to rotate the driving loop (84); a plurality of paddles (88) carried by the driving loop (84), the plurality of paddles (84) each being carried by the driving loop (88) to define a travel path (118) with a rotational component (126) that transitions into a linear component (122); and a housing (110) at least partially surrounding the driving loop (84) and the plurality of paddles (88). The invention is characterized in that the housing (110) has a region of divergence (140) relative to the driving loop (84) adjacent to the rotational component (126) of the travel path (118) and a region of convergence (144) relative to the driving loop (84) adjacent to the linear component (122) of the travel path (118). |
