The louver screen of cleaning the grain combine harvester comprises a frame, an adjustment mechanism of opening and louver. The louver is made in the form of combs. The combs of the central part of the sieve are made in the form of a bent movable plate. The combs of the side part of the sieve are made in the form of upper movable and lower fixed plates. The lower fixed plates are mounted on the frame with the possibility of their removal. The differential distribution of air flow is provided both along the length and width of the sieve in dependence of the load conditions.
