AXIAL-FLOW THRESHING AND SEPARATING APPARATUS Russian patent published in 1997 - IPC

FIELD: agricultural engineering. SUBSTANCE: apparatus has tubular shell enclosed in housing 1 with partition walls 2,3,4. Tubular shell has inlet cone 5, threshing housing 6 and separating housing 7 with guides 8,9 and 10 for axial conveyance of material. Branch pipe 11 with inner working surface is positioned between threshing housing 6 and separating housing 7. Rotor 12 with bladed impeller 13, threshing members 14 and 15 and separating member 16 on its outer surface is mounted in tubular shell for rotation within it. Stalk mass is delivered by conveyor 19 into cavity of inlet cone 5 and comes into engagement with guides 8,9,10 to be moved along tubular shell, where it is threshed and grain is separated from straw mass, which is discharged from apparatus through discharge window 20. EFFECT: increased efficiency, wider operational capabilities and enhanced reliability in operation. 3 cl, 2 dwg
