Grain tank and grain conveyor means of harvesting machines

摘要

According to the present invention a harvesting machine comprises a chassis with threshing and separating means and a power source mounted thereon and a grain tank pivotally mounted whereby it can be tipped to discharge grain contained therein rearwardly of the machine. The harvesting machine further also comprises a grain cleaning means mounted on the chassis and a conveyor means for loading grain into the grain tank. The conveyor means comprises a lower elevator extending from the grain cleaning means to the grain tank, an upper elevator mounted within the grain tank and aligned with the lower elevator when the grain tank is in the grain loading position, and disengageable coupling means disposed between the lower and upper elevators.
