Definitions

  • the invention relates to a percussion rotor according to the preamble of claim 1.
  • Crushers with impact rotors have been known for a long time. They represent an optimal solution to shredding problems.
  • the knife-free striking tools used can be optimally matched to the material to be shredded with different racket thicknesses. They shred waste wood down to blown material.
  • the goods to be treated can consist of waste wood, such as chipboard residues, veneer waste, pallets, etc., but also hard rubber products, waste, paper, glass, etc.
  • the components of such a shredding machine that are touched by the material are subject to wear. They therefore have a limited lifespan and must be replaced from time to time.
  • the rackets are particularly affected by wear.
  • the lifespan of the rackets is a few weeks to a few months, depending on the application and the type of goods. Then they have to be removed. It is possible to install the clubs upside down in such a way that the opposite striking edge becomes the working edge, which means that the service life achieved up to that point can be doubled. However, if this is no longer possible after a first turn, the worn rackets must be exchanged for new rackets.
  • the invention has for its object to design a percussion rotor according to the preamble of claim 1 such that the expansion of the racket compared to known percussion rotors is significantly facilitated.
  • the first main idea - according to claim 1 - provides to expand the bore to a certain extent in the direction of the rotor shaft.
  • the axis lies well in the reveal of the bore provided for the axis in the individual support disk.
  • a striking impulse is exerted on individual rackets for the purpose of releasing and pulling out the supporting axis, in that direction that the racket jumps into the recess. Due to the excess that this recess has compared to the diameter of the axis, the axis can now be easily pulled out of the supporting disks in the direction of its own longitudinal extent.
  • the two other main ideas according to claims 2 and 3 are related. It is provided according to the second main idea - claim 2 - to assign the bores of the support disks bearing bushes. These can consist of a bearing metal or plastic, for example.
  • the idea is surprising for the following reason: There was no discernible reason to provide the bores with such bushings, since there is no relative movement between the outer surface of the supporting axis and the reveal of the individual supporting disc during operation. There was therefore no need to avoid wear.
  • the bearing bushes according to the invention are inherently relatively playful. This game can increase during operation. However, this has no influence on the function of the machine. When replacing the racket, a slightly deformed support shaft can then be pulled out of the bearing points of the support discs.
  • the third main idea according to claim 3 has the advantage of easier assembly compared to the second main idea.
  • bushings 6 are inserted into the bores 5 of the supporting disks.
  • these bushings are made of plastic. They could also consist of a bearing metal.
  • These sockets 6 are the sockets according to the invention.
  • rackets 3 are mounted on the support axles 4 by means of bushings 7. Such sockets were already known before the invention.
  • the individual bore 5 in each support disk 2 merges into a recess 8.
  • the recess is also designed as a bore.
  • a hammer blow on the radially outer end of each racket or at least some of the rackets is sufficient, whereupon the axis 4 jumps into the recess 8 and can thus be easily pulled out of the plurality of support disks 2 in the direction of its own longitudinal extension.
