Spaltsieb, insbesondere für den Einsatz in Bauschuttaufbereitungsanlagen, Müllaufbereitungsanlagen und Absiebung von Humus und Torf, welches eine Vielzahl in der Förderrichtung angeordneter, quer zu dieser in Abstand voneinander gelegener Stäbe, Finger od.dgl. aufweist.The invention relates to a finger sieve or slotted sieve, in particular for use in building rubble processing plants, waste treatment plants and screening humus and peat, which has a plurality of rods, fingers or the like arranged in the conveying direction and at a distance from one another, at a distance from this. having.

Finger- bzw. Spaltsiebe bekannter Bauart haben bei der erwähnten Verwendung den Nachteil, daß beim Sieben klebriger, insbesondere stark klebriger Materialien das zu siebende Gut während des Gleitens über den Balken und entlang der Stäbe, Finger od.dgl. teilweise haften bleiben, wodurch der Siebeffekt beeinträchtigt und demzufolge ein häufiges Reinigen der Balken, Stäbe, Finger od.dgl. oder ein Austausch derselben bzw. des ganzen Siebes erforderlich ist, womit ein häufig langdauernder Stillstand der Anlage verbunden ist.Known type finger or slotted sieves have the disadvantage in the use mentioned that when sieving sticky, in particular very sticky materials, the material to be sieved during sliding over the bars and along the bars, fingers or the like. partially stick, which affects the sieve effect and consequently frequent cleaning of the bars, rods, fingers or the like. or an exchange of the same or of the entire screen is necessary, which is associated with a frequently long-term standstill of the system.

Durch die EP-A2 212.378 ist eine Siebvorrichtung mit einem seitlich nachgiebig eingespannten, eine rechteckförmige Siebfläche aufweisenden Siebbelag bekannt geworden, wobei von unten gegen diesen wirksamen Schlagleisten vorgesehen sind, die sich zwischen den Sieb-Einspannlagern erstrecken und die unter Einwirkung eines Schwingungsantriebs einen durch Wölbungshub senkrecht zur Siebfläche ausführen.From EP-A2 212.378, a sieve device with a laterally resiliently clamped sieve covering having a rectangular sieve surface has become known, effective beating strips being provided from below against it, which extend between the sieve clamping bearings and which, under the action of an oscillation drive, move through a bulging stroke Execute perpendicular to the screen surface.

Durch die WO 84/04474 ist ein Siebrost bekannt geworden, welcher an seinen beiden Enden an einem Rahmen befestigt ist, wobei mindestens ein Ende am Rahmen durch ein fehlendes Element angeschlossen ist, sodaß der Rost unter dem Einfluß von Vibriereinrichtungen schwingen kann.From WO 84/04474 a sieve grate is known which is attached to a frame at both ends, at least one end being connected to the frame by a missing element, so that the grate can vibrate under the influence of vibrating devices.

Beide zuvor genannten Siebeinrichtungen eignen sich wegen des früher genannten Nachteiles zum Sieben klebriger Materialien nicht.Both of the aforementioned screening devices are not suitable for screening sticky materials because of the previously mentioned disadvantage.

Aufgabe der Erfindung ist diesen Nachteil zu beseitigen. Zur Lösung der gestellten Aufgabe wird vorgeschlagen, daß erfindungsgemäß die Stäbe, Finger od.dgl. von einer Traverse, einem Balken od.dgl. fliegend gehalten sind und während der Förderung des zu siebenden Gutes schwingen. Dadurch wird eine Selbstreinigung der Stäbe, Finger od.dgl. herbeigeführt. Dieser Effekt ist besonders wirksam, wenn die Stäbe, Finger od.dgl. aus federndem Material bestehen. In diesem Fall ist durch das Schwingen der Stäbe, Finger od.dgl. eine Verstopfungsgefahr des Fingersiebes praktisch ausgeschlossen.The object of the invention is to eliminate this disadvantage. To solve the problem it is proposed that the rods, fingers or the like according to the invention. of a traverse, a beam or the like. are kept flying and swing while conveying the material to be screened. This will self-cleaning the rods, fingers or the like. brought about. This effect is particularly effective when the rods, fingers or the like. consist of resilient material.

Beim Übergang von einer Kaskade auf die andere, ist durch den Aufprall des Produktes nach einem freien Fall von ungefähr 10 - 20 cm Höhe, ein Auflockern und dadurch ein Zerteilen desselben auf den schwingenden Stäben, Fingern od.dgl. gegeben.The arrangement of these finger screens as cascade inserts appears to be essential. When transitioning from one cascade to the other, the impact of the product after a free fall of about 10-20 cm in height loosens and thereby breaks it up on the vibrating rods, fingers or the like. given.

Nach einem weiteren Merkmal der Erfindung sind die Stäbe, Finger od.dgl. in einer Traverse, einem Balken od.dgl. in Kunststoff eingegossen, wodurch ein Ausreißen der Stäbe, Finger od.dgl. aus der Traverse, dem Balken od.dgl. infolge der Schwingungen der Stäbe, Finger od.dgl. nicht möglich ist. Diese Wirkung kann noch dadurch verstärkt werden, daß nach einem weiteren Merkmal der Erfindung mindestens ein Teil der Stäbe, Finger od.dgl. gruppenweise oder alle Stäbe, Finger od.dgl. einer Reihe gemeinsam durch die Kunststoffmasse untereinander verbunden sind.According to a further feature of the invention, the rods, fingers or the like. in a traverse, a bar or the like. Poured in plastic, thereby tearing out the rods, fingers or the like. from the traverse, the beam or the like. due to the vibrations of the rods, fingers or the like. not possible. This effect can be further enhanced by the fact that, according to a further feature of the invention, at least some of the rods, fingers or the like. in groups or all rods, fingers or the like. a row are interconnected by the plastic mass.

Nach einem weiteren Merkmal der Erfindung können die Stäbe, Finger od.dgl. mit gleichem und bzw. oder verschiedenem Durchmesser und bzw. oder verschiedenen Spaltabständen fix eingegossen sein. Die Einspannung in die Traverse erlaubt ein rasches Wechseln dieser Beläge, wodurch nur geringe Stillstandzeiten der Anlage erforderlich sind.According to a further feature of the invention, the rods, fingers or the like. be cast in with the same and / or different diameter and / or different gap distances. Clamping in the crossbeam allows these coverings to be changed quickly, which means that only short downtimes of the system are required.

Schließlich kann nach einem weiteren Merkmal der Erfindung die Traverse, der Balken od.dgl. zumindest teilweise aus Kunststoff bestehen.Finally, according to a further feature of the invention, the traverse, the bar or the like. at least partially made of plastic.
