ROLLER SEGMENT FOR SEPARATING AND CLEANING DEVICES OF ROOT CROP HARVESTERS AND METHOD FOR ITS MANUFACTURE

摘要

A separating and cleaning device for a root crop harvester or similar sorting and cleaning devices of agricultural engineering provides that at least one separating and cleaning stretch is defined thereby. In its area, at least one roller is arranged that is assembled of one or several roller segments that in direction of a longitudinal roller axis are coaxially adjoining each other. These roller segments are provided with a jacket part comprised of an elastically yielding material and comprising entrainment ribs projecting outwardly. This jacket part interacts radially inwardly with a receiving area that is provided with recesses delimited by intermediate webs as well as a through opening, wherein the receiving area can receive a polygonal shaft or similar drive element for torque transmission The inventively improved concept of the roller construction is optimized such that the respective roller segments, beginning at their inner through opening, are provided with a multi-layer structure in radial direction.
