Abstract

Die Erfindung betrifft eine Siebvorrichtung mit mindestens zwei relativ zueinander bewegbaren Rahmen­ systemen, mit jedem System zugeordneten Roststäben, die paarweise ineinandergreifen und durch an ihnen befestigte, den Abstand zwischen den Stäben überbrückende flexible Siebelemente verbunden sind, welche durch die mittels einer ausschließlich an den beiden Systemen gelagerten und durch einen Antrieb in Drehung gesetzte Exzenterwelle (3) bewirkten Relativbewegung der beiden Systeme gespannt und entspannt werden. Diese bekannte Bauweise ist erfindungs­ gemäß dadurch verbessert worden, daß die Exzenterwelle an einem Ende der beiden Systeme (1,7) angeordnet ist und diese am anderen Ende oder in Abstand von diesem mittels eines Elementes (12), das eine im wesentlichen lineare Relativbewegung der beiden Systeme zueinander gewähr­ leistet, miteinander verbunden sind. Vorzugsweise entspricht der genannte Abstand dem Abstand, den der Beschleuni­ gungspol (PB) des schwingenden Systems (1,7) von der Exzenterwelle (3) aufweist. The invention relates to a screening device with at least two relatively movable frame systems, with each system assigned grate bars, which engage in pairs and are attached to them, bridging the gap between the bars flexible screen elements, which are connected by means of a means of only the two systems mounted and caused by a drive in rotation eccentric shaft (3) caused relative movement of the two systems can be tensioned and relaxed. This known design has been improved according to the Invention in that the eccentric shaft is arranged at one end of the two systems (1,7) and this at the other end or at a distance from this by means of an element (12) which has a substantially linear relative movement of the guarantees both systems to each other, are interconnected. Preferably, said distance corresponds to the distance that the acceleration pole (P B ) of the vibrating system (1,7) from the eccentric shaft (3).
