Sieve for a harvester thresher

摘要

The invention pertains to a sieve for a harvester thresher which consists of a frame and adjustable louvers that are mounted therein and can be adjusted by means of a motor-driven adjusting drive, wherein the sieve consists of at least two sieve elements that are arranged in the same plane and are respectively provided with a frame. In order to prevent the play of the adjusting drive and to adjust the louvers of the sieve elements independently of one another, the invention proposes to assign separate adjusting drives to the sieve elements.
