Abstract
A grain cleaning system for a combine harvester includes a chaffer and a sieve positioned below the chaffer. A first link includes a first end and a second end coupled to the chaffer. A second link includes a first end and a second end coupled to the sieve. A drive shaft is driven by a drive system to rotate about a shaft axis, wherein rotation of the drive shaft drives the first link to reciprocate the chaffer and drives the second link to reciprocate the sieve. The drive system is configured to control reciprocating motion of the chaffer and sieve with the goals of (i) minimizing vibrations of the cleaning system, (ii) minimizing destructive forces on the bearings (and other components) of cleaning system, and (iii) minimizing the power required to reciprocate the chaffer and sieve back and forth.
