GRAIN CLEANER Russian patent published in 2006 - IPC B07B9/00 B07B1/28 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to cleaning of grain and seeds of crops. Proposed machine contains frame, drive, intake hopper, aspiration system, settling chamber, cleaner shoe with working sieves and sieve cleaning members installed for vibration. Proposed cleaner shoe is made two-tier, in form of longitudinal bars and cross rods fitted in bars to form support grid for cleaning members. Longitudinal bars are clamped in vertical plane by studs with upper ends projecting over bars. Pressure strips are fitted on projecting ends of studs. Working sieves are clamped by means of studs between said strips and longitudinal bars. Cleaning members are arranged between cross rods and working sieves. Glass plastic is used to manufacture cross rods.

EFFECT: reduced mass of cleaner shoes, simplified design, reduced grain losses owing to improved quality and efficiency of aspiration process.
