Definitions

  • the invention relates to a knife for wood and wood chippers, its flat knife body with protruding cutting edge in an interchangeable holder a knife drum can be clamped.
  • the interchangeable holder In a known chopping machine, the interchangeable holder consists of two pressure plates for the two flat sides of the respective knife, the a pressure plate between two outer disks forming the remaining drum body arranged and the second pressure plate over one or more, too screws penetrating a corresponding opening in the knife body can be tightened.
  • the knife body itself represents a relative is a simple component, but must still be processed precisely and moreover be made entirely of a material that has a sufficiently long lifespan the cutting edge and thus the overall knife.
  • the blade can be a very simply shaped stamped part from one appropriate strength or hardening material, whereas the carrier body only the necessary support strength, but not for the cutting edge must have the necessary hardness or hardenability.
  • This support part with appropriate design of the overall construction also takes the for Interchangeable bracket and adjustment of necessary screws or screw bushings and screw supports. For this purpose it is provided that the blade and the recess of the carrier body receiving it only extend over part of the length of this support body.
  • the width of the blade is the flat side Correspond to the width of the carrier body in the receiving area, but are also Special shapes with the blade or support body protruding above the respective one other part possible.
  • a particularly simple construction results if the blade, based on the direction of rotation of the knife drum, at the front of the Carrier body arranged and can be pressed onto this by means of the interchangeable holder is. This has the additional advantage that it can be replaced the blade only has to loosen the clamping of the knife, the carrier body can remain in the interchangeable holder.
  • the blade points to that of the one or more projections on the side facing away from the cutting edge, corresponding to the lateral guidance of the blade relative to the carrier body engage shaped parts of the recess of this carrier body.
  • the blade with the carrier body is over engaging in assigned holes or depressions of the other part Pins, feather keys or the like additionally connected.
  • blades with one-sided cutting edge find use. But it is also possible to use the blade as a reversible blade with cutting edges provided on two parallel sides. Care must be taken to protect the cutting edge that has not been used remains. It will therefore be cut out in the recess of the carrier body and for the lateral support of the blade the above-mentioned pins, keys or provide similar brackets. In extreme cases, an execution is even conceivable according to the one initially square blade with cutting on all four sides is provided. For special cases, blades with serrated edges can also be used be used.
  • a knife drum has two side windows 1, each by fixed clamping plates attached at circumferential intervals 2 an interchangeable holder for cleavers are connected.
  • the clamping plates 2 wear cross bars 3 in which adjustment screws 4 and one for engaging in a threaded bore of the knife body certain tension-compression screw 5 are led.
  • the interchangeable bracket is assigned to each clamping plate 2 loose clamping plate 6 supplemented by a central screw 7, which the Knife body penetrating into a threaded hole of the plate 6, opposite the plate 2 can be clamped.
  • a knife body consisting of a carrier body 8 and a blade 9 appropriate.
  • the blade 9 is in a receiving recess 10 of the carrier body 8 inserted, protrudes with its cutting edge 11 over the carrier body 8 and is with the front edge part of the free clamping plate 6 clamped against the carrier body 8.
  • the blade 9a on the cutting edge 11th facing away from an arcuate projection 13 and the associated part 10a of the recess 10 in the carrier body 8a of FIGS. 9 and 10 is corresponding shaped.
  • the blade 9b is provided with holes 14 in the Pins 16 engage, which according to FIGS. 11 and 12 also have corresponding holes 15 in the Push through the area of the recess 10b of the carrier body 8b.
  • FIGS. 7 and 8 essentially corresponds that of FIGS. 5 and 6 with the exception that for the pins 16 in the Blade 9c slots 17 are provided.
  • 13 to 16 is a connection of the blade 9d or 9e with the carrier body 8d (FIGS. 17 and 18) through in elongated holes or elongated hole depressions of the two parts 18, 19 inserted keys 20 and the Blade 9d or 9e is an exchangeable or reversible blade with two cutting edges 11, 11a fitted.
  • 15 and 16 are the elongated holes 18e provided obliquely and the cutting edge 11b is - since it is a reversible blade acts - shaped opposite to cutting edge 11.
