Combine harvester with shakers for crop processing

摘要

The harvester has balance weights to compensate the free mass forces and moments of the crop processor (2). The balance weights may be integrated in the drive or processor itself. The compensators also move in relation to the processor movement or else come as a separate device which moves the opposite way to the processor. Kinematically linked shakers (2) and drive shaft (1) form a mass unit, with shaft journals (5) carried in the harvester frame and powered by belt (6) over pulley (7). The cranked shafts produce the mutually offset rotating movement of the shaker decks whose mass forces etc are counterbalanced by the fitted balance weights.
