Definitions

  • the present invention relates to a comminution machine, in particular for machining of fibrous material, especially for chopping wood.
  • Conventional Shredding machines have a screw conveyor to remove the wood chips on, which is arranged substantially parallel to the rotor axis and which at The shredding process removes the resulting chips.
  • a possibly behind the The suction device arranged in the screw transports the wood chips from the screw an ejection chute. This arrangement has the disadvantage that the screw conveyor Arrangement complicated and expensive.
  • a machine is already out of FI-B-95 109 known with a blower according to the preamble of claim 1.
  • the object of the present invention is to provide a comminution machine which is suitable to work without a screw conveyor.
  • Comminution machine according to the invention is characterized by a in the form of a Suction blower trained suction device that radially outside of the rotor such is arranged so that the chips generated by the rotor immediately behind the Rotor picks up and transported away.
  • the arrangement of a screw conveyor is omitted.
  • the fan is preferably on a conveyor belt with respect to the rotor arranged opposite side of the rotor. With this arrangement, that is on the Conveyor belt transported material to be shredded gripped by the rotor and tangential in one Conveyor belt transported opposite area of the rotor space, from where it is the Suction effect of the blower is transported away underneath.
  • the blower axis is located lower than that in the operating position of the shredding machine Rotor axis. This takes into account the fact that the place of crushing is in the area of the lower periphery of the chopping rotor, with the chips due to the Gravity is a downward tangential path from the rotor periphery describe.
  • the suction fan located below the rotor axis takes it Wood chips comfortably on.
  • a separating screen is arranged between the rotor and the fan.
  • the separating sieve has a mesh size set in such a way that only wood chips with one Pass the dimension below the mesh size and be transported away.
  • the Separating screen is adapted to the rotor periphery and therefore has at least one in cross section sectionally circular course.
  • the conveyor belt is angled in the area of the rotor space and into one Extended area below the rotor. This ensures that in the area of the rotor wood chips going down to an area of the angled one Conveyor belt section hit and transported further in the direction of the blower. In this way, the chips can be prevented from going down.
  • a chopping rotor 4 can be rotated with its rotor axis 1 in a rotor chamber 2 stored. Below the rotor axis 1 and to the left of it is in the horizontal direction a conveyor belt 6,8 out in the area of the rotor space 2 in one obtuse angle is angled.
  • a conveyor belt section 6 runs approximately horizontally, while at an angle, for example a roll Conveyor belt section 8 begins, which extends into an area below the rotor 4 or the rotor space 2 is extended.
  • a counter-conveyor belt 10 which its upper role is fixed, its lower role is self-supporting, so that the conveyor belt 10 depending on the size of the comminuted material is more or less inclined.
  • a separating screen 18 is provided on the circumference of the chopping rotor, which limited and chosen in its mesh size so that only enough fine Wood chips with a diameter below the mesh size the rotor space being able to leave.
  • a suction fan 12 the axis of which 14 is arranged substantially horizontally and perpendicular to the rotor axis 1.
  • the fan axis 14 is located below the rotor axis 1 and is also located lower than the upper run of the conveyor belt section 6.
  • the suction fan 12 has blades 16 which, due to their inclined position, have a suction effect unfold.
  • the overall diameter of the suction fan 12 is chosen to be the blades extend into the area of the center of the rotor axis 1 extend upwards.
  • the overall diameter of the blower is also so chosen so that it covers the entire length of the rotor, so that the fan in its entire depth provides sufficient suction to get everyone out of the Rotor chips emerging from the rotor chamber.
  • the one below the rotor space 2 extended conveyor belt section 8 ensures that outgoing downward Wood chips taken from the conveyor belt 8 in the direction of the blower 12 become.
  • the suction fan at its suction opening is particularly preferred reduced in cross section (not shown) to increase suction achieve.
