TRANSMISSION MECHANISM OF DRIVING FORCE IN THRESHING PART OF COMBINE HARVESTER

摘要

PROBLEM TO BE SOLVED: To provide a transmission mechanism of driving force in a threshing part of a combine harvester without making lateral width of the mechanism larger than needs. SOLUTION: In this transmission mechanism, a distribution transmission mechanism 33 for distributing driving force from an engine 6 to the side of a threshing cylinder 14 and the side of separation part and transmitting the power is arranged on forward side of a discharge cylinder 9 for discharging grains from the side of threshing part 3 to form a structure in which the driving force is distributed and transmitted through one belt 32 to the side of a driving shaft 25 of the threshing cylinder 14 and a driving shaft 28 of a separation fan 18, and at least a separation part is driven by the driving shaft 28 of the separation fan 18.
