SEPARATOR SCREEN Russian patent published in 2016 - IPC A01F12/24 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building. Combine harvester separator separating screen comprises spaced apart arched frame parts. Between frame parts in fixed position turning webs or axes are located passing across frame parts, which make separation surface with through cells. In through cells between rotation webs or axes finger-shaped elements are arranged uniformly passing in circumferential direction, which in separating screen axial direction are arranged with average axial distance from each other. Each finger-shaped element along its length has medium width. Finger-shaped element medium-width ratio to average axial distance between finger-shaped elements is at least 1:3.5. Several finger-shaped elements are arranged on one frame element, which contains first flange and second flange located at angle to it. On frame elements on turned away from corresponding finger-shaped element side at least one plank is located, which projects beyond frame element first flange in radial direction.

EFFECT: separator screen in cost-saving manner ensures variation of its separation capacity depending on sample type and harvesting conditions.
