Roller segment for separating and cleaning devices in root crops and method for its production

摘要

A separation and cleaning device for a root crop harvester o. The like. Sorting and cleaning systems of agricultural technology provides that while at least one separation and cleaning section is defined. In the region thereof, at least one roller composed of one or more roller segments coaxially adjoining in the direction of a roller longitudinal axis is arranged. These roller segments have a casing part made of elastically yielding material and shaped with outwardly projecting driving ribs. This casing part cooperates radially on the inside with a recesses bounded by intermediate webs and a receiving region having a passage opening, wherein the latter can in turn receive a polygonal shaft or the like. The inventively improved concept of roll construction is optimized so that the respective roll segments are provided starting from the inner through-hole in the radial direction with a multilayer structure.
