FIELD: agriculture.
SUBSTANCE: fan of the grain harvester cleaning system contains a rotor placed in the housing. The discharge branch pipe is formed by the upper and lower walls and side panels. In the discharge branch pipe, an air flow guide with rectilinear edges is installed between the side panels. In the discharge branch pipe between the top and the bottom walls, symmetrically from the transverse axis of the fan, vertical air flow guides are installed. The vertical guides are made in the form of curvilinear surfaces and are directed from the middle to the periphery of the fan.
EFFECT: fan provides uniform air distribution in the working area of the cleaning system, which increases the cleaning quality of a grain heap.
