Abstract

Eine Trommelhackmaschine für die Zerspanung von Holz hat einen Rotor (2) mit mehreren in axialer und tangentialer Richtung gegeneinander ver­ setzten Hackmessern, die mit einem gemeinsamen Gegenmesser bzw. einer Am­ boßleiste zusammenarbeiten. Unterhalb des Rotors (2) ist ein auswechselba­ rer Siebkorb (9) angeordnet, dessen Öffnungen (10) die Größe der durch die Hackmesser erzeugten Hackschnitzel bestimmen. Hackschnitzel, welche so groß sind, daß sie die Öffnungen des Siebkorbes (9) nicht passieren kön­ nen, werden vom Rotor (2) mitgenommen und so lange erneut dem Gegenmesser bzw. der Amboßleiste zugeführt, bis die Hackschnitzel den Siebkorb passie­ ren können. Die durch die Öffnungen (10) hindurchtretenden Hackschnitzel fallen auf eine geneigte Gosse (13) in Form einer schräg gelagerten Mulde, von dort rutschen die Hackschnitzel in das Gehäuse eines Gebläses (14), was durch die von den rotierenden Armen des Rotors hervorgerufene Luft­ strömung unterstützt wird. Auf der Achse (5) des Rotors (2) sitzen die Flügelarme (15) des Gebläses (14), welche zugleich Schwungarme zur Über­ brückung von Spitzenbelastungen bilden und das dem Gebläse (14) zugeführte Hackgut ausschleudern (Fig.1). A drum chipper for cutting wood has a rotor (2) ver with several in the axial and tangential direction against each other set cleavers with a common counter knife or an Am work together. Below the rotor (2) is a replaceable rer sieve basket (9), the openings (10) of which are the size of the Determine the wood chips produced. Wood chips, which so are large that they can not pass the openings of the strainer (9) NEN, are carried by the rotor (2) and so long the counter knife or fed to the anvil bar until the wood chips pass the sieve basket can. The wood chips passing through the openings (10) fall on an inclined gutter (13) in the form of an inclined hollow, from there the wood chips slide into the housing of a blower (14), what is caused by the air caused by the rotating arms of the rotor flow is supported. They sit on the axis (5) of the rotor (2) Wing arms (15) of the blower (14), which at the same time swing arms for over bridge peak loads and the blower (14) supplied Spin out the wood chips (Fig. 1).
