Definitions

  • the invention relates to a chipper for wood chips.
  • chippers have become known in a variety of embodiments. For example, reference is made to DE-U-93 07 371.
  • Such chippers are supplied with wood chips of a certain size, with the aim of breaking down the wood chips into chips, which are mainly processed by the chipboard industry.
  • a chip extraction duct follows the gap in the radial direction. This channel is formed from the outer surface of the knife carrier of the one knife pack and from the outer surface of the clamping plate of the other knife pack.
  • the space is limited, on the one hand due to the diameter of the knife ring and on the other hand due to the fact that the individual knife pack - viewed in the circumferential direction - occupies a certain minimum space, due to the structurally required strength of the three components of the knife pack mentioned, namely of the carrier, the knife and the clamping plate.
  • the knife packs cannot be as close together as desired. This would mean a reduction in the size of the chip extraction channel.
  • the invention is based on the object of designing a chipper of the type mentioned in such a way that, for a given knife ring diameter, even more knife packs than previously can be accommodated on the knife ring.
  • the inventor has recognized that the clamping plate can be made much thinner than it has since, given the appropriate design - namely the arrangement of a rib.
  • the knife packs can thus be moved closer together, so that a larger number of knife packs can be accommodated on a knife ring of a given diameter, but at the same time the width of the chip extraction channel is retained.
  • the stiffening rib according to the invention extends above all to the radially inner end of the clamping plate. This is important so that the necessary clamping force is still transmitted from the clamping plate to the knife there, and so that there is no gaping between the radially inner clamping plate tip and the knife.
  • the rib can even extend in the radial direction beyond the radially inner main edge of the clamping plate.
  • the individual stiffening rib is suitably designed so that it affects the flow of chips as little as possible.
  • the edge of the rib which is flown against by the chips is expediently formed with sharp edges, so that current is divided.
  • This flowed edge can also be hardened or consist of a particularly hard, inserted part.
  • the clamping plate can not only be made thinner overall, but it can also taper particularly strongly in the direction of the cutting edge of the knife, so that the radially inner end of the clamping plate forms a very acute angle.
  • the knife packs according to FIGS. 1 to 4 each comprise a knife holder 1, a clamping plate 3 and a knife 2 clamped between them.
  • the decisive feature according to the invention is a stiffening rib 3.1, which is molded onto each cutter plate 3.
  • the stiffening rib 3.1 in the exemplary embodiment shown is advanced over the front edge 3.2 of the clamping plate 3, in the direction of the cutting edge 2.1 of the knife 2.
  • Figures 3 to 8 each have a guide body 4. This can be inserted into the knife package from the side. It has different cross sections, as can be seen from the figures. For example, it has a cross-shaped cross section in FIG. 3 and a T-shaped cross section in FIG. 4.
