Definitions

  • the invention relates to a Rotorshredder according to the preamble of patent claim 1.
  • Rotorshredder are crushing machines, which work on the principle of shear cutting. Such crushing machines are widely used for recycling of raw materials, with a variety of different products, such as sheet metal parts, tires or refrigerators with such crushers are comminuted.
  • Such a previously known Rotorshredder consists of a very stable trained, torsion ungssteifen cutting frame, in the Strininin at least one example, electric motor driven cutting shaft is mounted. On the cutting shaft, a plurality of cutting discs are arranged, which regularly carry a plurality of cutting heads. The cutting disks are arranged at a distance from one another and cooperate with a further tool, wherein as a further tool a stationary scraper or else a second cutting shaft rotating relative to the cutting shaft is provided with cutting tools.
  • the cutting gap between the cutting discs or even between a cutting disc and the scraper is only a few tenths of a millimeter in order to achieve the desired cutting result.
  • the cutting frame is designed to be stable and rigid connection so that no distortion on the cutting frame occur even with a crushing of very hard or tough material, causing the kerf between the cutting discs would be changed.
  • the invention aims to remedy this situation.
  • the invention has for its object to provide a Rotorshredder of the aforementioned type, in which a change of the cutting shafts is made possible without any disassembly of the cutting frame.
  • this object is solved by the features of the characterizing part of patent claim 1.
  • a Rotorshredder is provided in which a change of the cutting shafts is made possible without any disassembly of the cutting frame.
  • At least one outwardly projecting wing for attachment to the respective end wall is arranged laterally on the bearings of the at least one cutting shaft.
  • a laterally projecting flange is integrally formed on at least one bearing, which is externally fitting to the associated Strinwandschneid- works frame with this screwed. As a result, a robust attachment of the bearing is achieved on the cutting frame.
  • the at least one laterally outwardly projecting wing is formed by a web whose outer longitudinal side terminates with the protruding flange and the inner longitudinal side with the inside of the end wall.
  • a nose is formed on the at least one outwardly projecting wing which corresponds to a recess arranged next to a substantially U-shaped recess.
  • Fig. 2 shows the three-dimensional representation of the junction between
  • FIG. 3 shows the representation of the connection point of Fig. 2 in the rear view
  • the rotorshredder selected as an embodiment comprises a cutting frame 1, which consists of two opposite side walls 11 and two opposite, the two side walls 11 frontally interconnecting end walls 12.
  • a cutting frame 1 which consists of two opposite side walls 11 and two opposite, the two side walls 11 frontally interconnecting end walls 12.
  • the U-shaped recesses 13 serve to receive the bearings 22 of the cutting shaft 2.
  • a recess 14 with a substantially rectangular cross-section is arranged spaced therefrom on both sides.
  • the U-shaped recesses 13 are further lined with threaded bores 15.
  • the end walls 12 serve to receive the bearings 22 of two cutting shafts 2, which are each equipped with a plurality of cutting discs 21.
  • the cutting discs 21 of the two cutting shafts 2 are offset and arranged with a only a few tenths of a millimeter measuring kerf to each other.
  • the bearings 22 of the cutting shafts 2 have a U-shaped outer contour, which corresponds to the U-shaped recess 13 of the respectively associated end wall 12.
  • a laterally projecting flange 24 is formed, which also has a U-shaped outer contour.
  • holes 241 are introduced, which correspond in the mounted state with the threaded holes 15 of the recess 13 of the end wall 12.
  • the flange 24 opens into a web 23 which terminates with its outer longitudinal side with the flange 24 and with its inner longitudinal side with the inside of the end wall 12.
  • the web 23 projects beyond the flange 24 on both sides, so that protruding wings 231 are formed.
  • the two cutting shafts 2 are driven by drive units 3 which are shown schematically in each case and which are connected to the cutting shafts 2 via gearboxes 4 likewise shown schematically.
  • the cutting frame 1 is set up and adjusted at a first start of the Rotorshredders by appropriately screwing the side walls 11 with the end walls 12. For changing the cutting shafts, no disassembly is obviously made on the cutting frame, so that a misalignment of the cutting frame in the course of a cutting shaft change is excluded. From the description of the invention it is clear that a cutting shaft change in the invention Rotorshredder due to the attachment of the specially designed bearing in the corresponding thereto formed recess 13 of the end wall 12 can be made easily and with little change time. Unforeseen time losses due to impairment of the cutting frame are largely excluded.

Abstract

La présente invention concerne une broyeuse à rotors, comprenant un châssis de mécanisme de coupe constitué de deux parois latérales reliées entre elles par deux parois d'extrémité et dans lesquelles est monté rotatif au moins un arbre de coupe. Les parois d'extrémité (12) du châssis de mécanisme de coupe (1) présentent au moins un évidement (13) sensiblement en U accueillant les paliers (22) de l'arbre de coupe (2). Les paliers (22) sont configurés de façon à présenter un contour extérieur en U correspondant à l'évidement en U (13) des parois d'extrémité associées (12).
