摘要：
The invention relates to the field of agricultural engineering, in particular to combine harvesters. To extend technological capabilities, improved performance, in a continuous-flow harvester, comprising a header, feeder, a blower, and provided with the receiving screw device threshing and separation unit, configured in the form of coaxially mounted with clearance screw drums, for example three, external, middle and internal, with this outer drum is made to form a multi-start helical surface around the perimeter of three or more folded in the vertical plane and the serial but interconnected strips of variable width convex curved shape rolled in the longitudinal direction in the vertical plane, are bent in helical lines in the transverse direction and bent on the notch, with oblique walls in the cross-longitudinal direction, arranged pairwise at an angle to one another on both sides strips to form the perimeter of the drum directed towards each other polygonal helical lines and broken helical surfaces with the same variable pitch length of the drum, and the middle bar bath assembled of sections to form a multi-start helical surface made of several equilateral perforated triangles in an amount multiples even number, for example twelve interconnected by two lateral sides, the sections are connected with each other by free third side of the triangle to form a helical drum by the perimeter of which there are directed towards each other right and left broken lines screw line provided with internal helical groove direction nnym towards each other with the same constant pitch along the length of the average of the drum, the end openings of helical drum side loading between the inner and middle reel, and between the middle and outer drums closed shell to supply them the air flow from the fan, wherein the mechanical internal drum hole opened by the download, and all the holes are visible by the three reels and unloading device through the feed screw and the inner cavity of th
