FIELD: agricultural machine engineering, possibly cleaning apparatuses for grain harvesting combines.
SUBSTANCE: centrifugal fan includes body having two sections and pumping branch pipe; impeller. Each section of fan body includes outer and inner side members with suction windows. Impeller includes vanes secured to common shaft of fan. Vanes of each section are mounted by acute angle relative to planes of outer side members of sections. Vanes arranged near inner side members of each section are shifted forwards in rotation direction of impeller relative to ends of vanes arranged near outer side members.
EFFECT: improved design providing uniform air flow along width at outlet pumping branch pipe, increased separating capability of cleaning grids of harvesting combines.
