Description
Gegenstand der Erfindung ist eine Trommelhackanlage, die einen Rahmen, eine Aufgabevorrichtung, eine mit Messern bestückte Trommel einschließlich Rotationsvorrichtung, ein Gegenmesser, ein unter der Trommel angeordnetes Sieb und einen unter dem Sieb befindlichen Hackschnitzelförderer umfaßt.object the invention is a drum chipper, the one frame, a Feeding device, a drum equipped with knives including rotating device, a counter knife, a sieve arranged under the drum and a lower comprising the sieve.
Man kennt unter der Typenbezeichnung Ahlström R 910 eine Trommelhackanlage der in der Einleitung genannten Art. Der Hersteller verkauft diese auch auf Kraftfahrzeuge montiert, wobei die Anlage dann eine Ladevorrichtung zur Eingabe des Holzes in die Hackmaschine hat.you Known under the type designation Ahlström R 910 a drum chipper the type mentioned in the introduction. The manufacturer sells them as well mounted on motor vehicles, the plant then a charging device to enter the wood in the chipper has.

Bei den bekannten Anlagen tritt als Problem Siebverstopfung und als Folge davon schwieriges Reinigen der Vorrichtung sowie umständliche Handhabung mehrerer verschieden großer Siebe in Erscheinung. Für die einzelnen Einsatzzwecke müssen nämlich jeweils Hackschnitzel einer bestimmten Größe hergestellt werden, und dies bewerkstelligt man bei den heutigen Anlagen jeweils durch Einsetzen eines Siebes mit anderer Maschenweite. Bei den gegenwärtigen Anlagen muß im Verstopfungsfall das Sieb meistens vollständig ausgebaut und die Hackmaschine geöffnet werden.at the known plants occurs as a problem Siebverstopfung and as Result of difficult cleaning of the device and cumbersome Handling several different sized screens in appearance. For the individual For each purpose must be Wood chips of a certain size are produced, and this is accomplished in today's systems each by inserting a sieve with a different mesh size. At the current facilities must be in Constipation case, the sieve mostly completely removed and the chipper open become.
Mit der vorliegenden Erfindung sollen die vorgenannten Mängel beseitigt werden und eine gebrauchsleichte, auf jeweils gewünschte Hackschnitzelgröße einstellbare Trommelhackanlage geschaffen werden. Die charakteristischen Merkmale der Erfindung sind in dem beigefügten Patentanspruch 1 aufgeführt. Vorteilhafte Ausgestaltungen finden sich in den Unteransprüchen.With The present invention is intended to overcome the aforementioned deficiencies and a customizable, on each desired chip size adjustable Drum chopper be created. The characteristic features The invention are in the attached Patent claim 1 listed. Advantageous embodiments can be found in the subclaims.
Das zweiteilige Sieb mit verstellbarer Maschenweite ist in der Praxis ein gutes Mittel zur Behebung eventueller Verstopfungen. Der Hackschnitzelauswerfer muß in diesem Falle zumindest zu einem gewissen Grade mit Sog arbeiten, wodurch er zur Sauberhaltung des Siebes beiträgt. The Two-piece sieve with adjustable mesh size is in practice a good remedy for any blockage. The woodchip ejector must be in working with suction to a certain extent in this case, whereby it contributes to the cleanliness of the sieve.
Im folgenden wird die Erfindung unter Bezugnahme auf die beigefügten Zeichnungen, die eine erfindungsgemäße Trommelhackanlage sowie Details derselben zeigen, im einzelnen beschrieben. Es zeigen:in the In the following, the invention will be described with reference to the attached drawings, a drum chopper according to the invention as well as details of the same show, described in detail.

Die erfindungsgemäße Trommelhackanlage ermöglicht die Herstellung von Hackschnitzeln entsprechend den jeweiligen Qualitätsansprüchen des Käufers. Die maximale lichte Maschenweite (100 mm × 60 mm) ermöglicht die Herstellung großer Hackschnitzel etwa für Energieerzeugungszwecke. Ist eine engere Maschenweite eingestellt, so liefert die Anlage kleinere Hackschnitzel, die dann zum Beispiel für einen Weitertransport durch Förderschnecke geeignet sind. Bei eventuellem Auftreten einer Betriebsstörung können die beiden Siebschichten relativ zueinander hin und her bewegt werden, und auch der Sog unterhalb des Siebes kann erhöht werden. In den meisten Fällen läßt sich allein dadurch die Verstopfung beheben, ohne daß unnötiger Arbeitszeitausfall durch Reinigen der Anlage entsteht.The drum chopper according to the invention allows the Production of wood chips according to the respective quality requirements of the buyer. The maximum clear mesh size (100 mm × 60 mm) allows the Producing large Wood chips for about Power generation purposes. If a narrower mesh size is set, so the system delivers smaller chips, which then, for example for one Further transport by screw conveyor suitable are. If a malfunction occurs, the two screen layers be moved back and forth relative to each other, and also the suction below of the sieve can be increased become. In most cases let yourself solely by the constipation repair without unnecessary lost working time by Cleaning of the system is created.
Zwar wird als Hackschnitzelauswerfer bevorzugt ein Zentrifugalgebläse der im Beispiel gezeigten Art verwendet wird, aber, besonders unter Fabrikverhältnissen, kann stattdessen unter dem Sieb auch ein konventioneller Bandförderer eingesetzt werden.Though is preferred as a chip ejector a centrifugal fan in the Example shown, but, especially under factory conditions, Instead, a conventional belt conveyor can be used under the screen become.
