Embodiment Construction

[0058] The screening belt unit 1 according to the invention according to figure 1 Shown is a sifting belt 2 which is arranged to sieve extras from the mixture of harvest and extras. The screening belt 2 has two continuous carriers 3 designed as carrier belts, between which screen bars 4 and 6 are arranged transversely to the conveying direction. The conveying direction F has different inclinations with respect to a horizontal line (not shown) in the course of the screening zone S formed by the upper run of the screening belt 2 . These inclinations result from the positioning of deflection rollers or deflection disks 7 , which can be configured in part as drive disks. The tensioning rollers 8 tension the screening belt 2 relative to the drive rollers 9 so that, depending on the adjusted inclination of the screening belt in the individual screening belt regions, there is sufficient contact with the driving rollers 9 .

[0059] Each sieve bar 4 and 6 that will also elaborate be...

Abstract

The invention relates to a screen belt unit for a harvesting machine or crop conveyor device, in particular to a root crop harvester or a root crop conveyor belt, and for separating trash from a mixture of crops and trash, the belt unit comprising a screen belt (2) having at least two endless carriers, preferably designed as carrier belts or chains (3), with screening bars provided therebetween ina direction running transversely to the conveying direction, said bars forming a plurality of screening bar units (11) which each comprise, in particular, at least two screening bars (4, 6). At leastsome of the screening bars (3) are fixed in position relative to the endless carriers, the screen belt unit (1) has a positioning means (13), at least some portions of which are located along the screen belt (2) and act on the movable screening bars (6), and which is used to define and in particular variably set, in the screening zone S, viewed in the screening direction, a distance A in the conveying direction F of successive screening bars. The invention also relates to an associated shutter unit.

Description

technical field [0001] The invention relates to a screening belt unit for a harvester, in particular for a root crop harvester, for screening out additions, in particular Sieve out the additions in the form of soil, clods and stones, wherein the screening belt unit comprises a screening belt with at least two continuous carriers preferably configured as carrier belts or carrier chains, in Sieve bars are arranged between the continuous carriers in a direction transverse to the conveying direction, and the sieve bars are configured as a plurality of sieve bar units, in particular each comprising at least two sieve bars, wherein at least part of the sieve bars are opposite to each other. Removably fixed on a continuous carrier. Background technique [0002] When harvesting and conveying root crops, in particular potatoes, through screening belts of this type, on the one hand, unwanted soil-form deposits should be carried along in a targeted manner either in order to protect th...
