SUBSTANCE: invention relates to agricultural machine building, particularly, to lactic culture harvesting machines. Slot beater of threshing-separating device comprises base 1 with blades 2 fixed on it. Each blade 2 has bracket 3 and has curved working surface convexity forward, which from base 1 to periphery ends with limiter 4. Front part of the protrusion has threshing edge 5, between which slit 6 is formed between the limiter and limiter 4. Each blade 2 is equipped with transporting plate 7 and is connected to base 1 by means of screws 8, on which they are able to move along slots 9 made in blades 2.
