FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machinery, in particular to working elements of winnowers, and may be used in agriculture and elevator industry. Sieve boot of winnower includes movable body with tray and chutes for material fractions discharge. Inside body there are two tiers of replaceable flat sieves, and beneath there are frame winnowing devices. There are drive mechanisms to drive body and winnowing devices. Mechanism of winnowing devices drive is arranged in the form of lever-gear-rack mechanism, on shaft of geared wheel of which there is a driving sprocket rigidly fixed and connected to tension sprocket by vertically closed chain. Frames of winnowing devices are connected to upper and lower branches of closed circuit passing inside body.
EFFECT: improved efficiency of sieves cleaning, and also longer service life, reduction of dimensions by width and metal intensity of sieve boot.
