Adjusting device for sieves

Abstract

Abstract 1. Adjusting device for lamellae (30) of at least one sieve (28) suspended to oscillate on swinging arms, of agricultural machines, especially combine harvesters, wherein the lamellae (3) are adjustable their opening angle through a regulating shaft (50) running transverse to the conveying direction of the sieve (28) and participating in the oscillating movement of the sieve (28), which shaft is connected to at least one regulating part (40) displaceable in the conveying direction of the sieve (28) and engaging with lamella carriers (32) of the lamellae (30), solely by rotation of the regulating shaft (50) by swinging a regulating lever (66), characterized in that the regulating lever (66) is mounted in a fixed position on the machine and is pivotally connected by a vertical rod (64) to a tongue (58), which extends in the conveying direction of the sieve (28) and is fixedly connected to the regulating shaft (50), wherein the regulating lever (66), tongue (58), vertical rod (64) and one swinging arm form a parallelogram-like linkage arrangement, which exerts no action on the position of the lamellae (30) through the oscillating movement of the sieve (28).
