Combine harvester cleaning mechanism including grain pan.

摘要

A combine harvester has threshing and separating means (9) and a grain cleaning mechanism (21) disposed beneath the threshing and separating means (9). The cleaning mechanism (21) comprises a grain pan (22) fitted with movable divider means (41) and is operable to receive grain from the threshing and separating means (9). The cleaning mechanism (21) further also comprises sieve means (23, 24) operable to receive grain from the grain pan (122) and fan means (25) operable to blow air through the sieve means (23, 24). The sieve means (23, 24) may comprise sieve sections (94) which are pivotable around fore-and-aft extending axes (101). The harvester further also comprises inclination sensing means (75) for sensing the lateral inclination of the machine and actuator means (50) operatively coupled to the grain pan divider means (41) and/or the movable sieve sections (94) for adjusting said grain pan divider means (41) and/or said movable sieve sections (94) in response to the output of the inclination sensing means (75) to compensate for any given lateral inclination of the harvester. <IMAGE>
