FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machine building and may be used in cleaning systems of combine harvesters and stationary winnowing machines. Lipped screen comprises rotary plates installed parallel in frame and arranged along sides from axis of rotation and having upper and lower working surfaces. Upper working surface is arranged along longitudinal edge with flat comb, tabs of which are shaped as flat segments. Between comb tabs there are bent teeth oriented from plane of comb downwards and towards lower working surface, which is arranged with through slots opposite to specified teeth and is bent downwards. Bent teeth have shape streamlined in cross section. Rotary plates are installed in frame one behind another at the distance providing for the possibility of bent teeth of one plate to enter in according slots of the neighbouring one.
EFFECT: design of lipped screen eliminates swirling of air flows around comb, which provides for efficient operation of screen.
