Definitions

  • the invention relates to a removal roller for a bale opener, on the circumference of which teeth are detachably fastened.
  • threads are cut into the casing of the removal roller, into which teeth are screwed (DE-OS 3,210,602 and US-A-3 325 880).
  • the teeth are designed as double teeth.
  • the wall of the roller must be correspondingly strong in order to avoid tearing out the teeth.
  • the removal roller becomes heavier and more expensive to manufacture.
  • the roller becomes unusable and would have to be replaced with considerable effort as soon as a thread is destroyed.
  • the object of the invention is to provide a removal roller, on the circumference of which the teeth are fastened in a simple and reliable manner and are easily replaceable.
  • the object is achieved in that the teeth are provided with a support surface adapted to the circumferential contour of the removal roller and are screwed into dowels.
  • the contact surface is reduced to two support shoulders spaced apart from one another.
  • the dowel preferably has two shoulders, one of which is arranged outside and the other inside the jacket of the removal roller. This firstly ensures a positive clamping of the tooth and secondly prevents the dowel from falling through the bore into the interior of the removal roller. A stable position of the tooth is achieved in that the dowel with a rectangular cross-section sits in the receiving opening of the eye of the receiving surface.
  • the teeth are expediently designed as double teeth.
  • a tooth 2 is screwed into the dowel 4 by means of a screw 3 on the lateral surface of a removal roller 1, which is inserted into a bore 5 in the wall of the removal roller 1.
  • the tooth 2 has a support surface 21 which is adapted to the peripheral contour of the removal roller 1 and extends in the peripheral direction over a section of the roller shell.
  • the tooth with its entire contact surface 21 is only supported if the removal roller is highly accurate. Since this is usually not the case, the support is reduced to two support shoulders 22 and 23 which are arranged at a distance from one another in the circumferential direction are, in the exemplary embodiment at the ends of the receiving surface 21.
  • the dowel 4 consists of a rectangular part 41 and a round part 42. With the rectangular part 41, it sits in a likewise rectangular receiving opening 51 of the eye 5 of the receiving surface 21 and with the round part 42 in a bore in the jacket of the removal roller. Both on its rectangular part 41 and on its round part 42, the dowel 4 is provided with a shoulder 43 and 44, respectively.
  • the shoulder 43 arranged outside the jacket of the removal roller 1 prevents the dowel from falling into the interior of the removal roller after the screw 3 has been unscrewed.
  • the beveled shoulder 44 in the interior of the removal roller lies against the inner wall of the shell when the screw 3 is tightened and ensures that the tooth is positively clamped onto the roller shell.
  • the insertion of the dowel 4 into the bore in the roller shell and the removal over the shoulder 44 is made possible by a longitudinal slot 45 in the dowel 4.
