GRAIN COMBINE CLEANER Russian patent published in 1999 - IPC

FIELD: agricultural engineering. SUBSTANCE: grain combine cleaner has sieve shoe with carcass constructed from sides and transverse beams, upper and lower sieves, hydraulic cylinder for regulating transverse inclination of sieves, fan and rocking mechanism. Sieves are positioned in carcass for rotation relative to spherical joints mounted on front transverse beams and are connected with rear transverse beams through guides and rollers positioned on sieves. Construction of grain combine cleaner provides full leveling of sieves relative to horizontal plane during advancement on slopes. EFFECT: increased efficiency by reduced grain loss and enhanced reliability in operation. 3 dwg
