Definitions

  • the invention relates to a comminution device, in particular for bulky waste material, with a comminution roller, and with a feed chute which has a bottom lying to the side of the comminution roller and a wall which extends parallel to the comminution roller and extends to the bottom and can be moved towards the comminution roller.
  • Such a shredding device can be found, for example, in US Pat. No. 4,723,717.
  • There are several intermeshing shredding rollers at the end of a feed shaft the device being arranged so that the feed shaft rises at an angle and the shredding rollers are arranged one above the other.
  • a slide can be moved in the feed shaft, by means of which the material to be shredded is pressed against the shredding rollers.
  • the shaft can only be filled when the slide is removed from the shredding rollers.
  • Both versions are structurally relatively complex and the invention has set itself the task of simplifying a shredding device of the type mentioned.
  • the comminution device thus has a funnel-like feed chute above the comminution roller, in which a wall is arranged pivotably.
  • the pivotally arranged wall can be a side wall of the filling shaft, which is accessible at all times, or a pivoting flap arranged in the shaft.
  • the circular arc of the curved bottom runs approximately through the axis of the comminution roller.
  • the material in the vicinity of the curved base is thereby pressed approximately radially to the roller axis, and a cutting length of approximately one third of the roller circumference is achieved.
  • a further preferred embodiment provides that two mutually co-rotating, intermeshing shredding rollers are arranged obliquely one above the other, the common axial plane of which is inclined approximately 25 ° to 30 ° to the vertical. This preferably results in an approximately vertically symmetrical arrangement with respect to the movable wall when it is moved towards the comminution roller.
  • the opposite side wall of the feed chute can have an incline, which has a free space for the material that has been displaced from the movable wall and is still undiminished.
  • the inclination can be, for example, between 50 ° and 60 °, the lower edge being approximately in the middle above the comminution roller.
  • the angle of inclination also depends on the height of the movable wall.
  • a preferred execution of the material results in a preferred embodiment, in which the opposite one Wall is pivotable about an axis parallel to the shredding roller along a second base curved in the shape of a circular arc.
  • the two walls preferably have a common drive and can be pivoted in parallel via connecting links.
  • FIG. 1 to 3 show schematic vertical sections of a first embodiment of the comminution device and FIG. 4 shows a vertical section corresponding to FIG. 1 of a second embodiment.
  • a comminution device has a housing, the upper part of which forms a feed chute 1 with a rectangular cross section and in which a comminution roller 5 is arranged below the feed chute 1 according to FIGS. 1 to 3 and has cutting or fang 12 on the circumference.
  • the shredding roller 5 can also be composed of individual shredding disks.
  • the comminution roller 5 is surrounded on the side facing away from the feed chute 1 over a good half of its circumference by a perforated screen 10 or the like, the hole diameter of which determines the size of the material falling down.
  • the perforated screen 10 can be arranged interchangeably. Below the perforated screen 10, a screw conveyor 13 for discharging the shredded material is shown; this is of course not mandatory.
  • two comminution rollers 5, 6 are arranged offset one above the other in order to increase the cutting performance, which are driven in the same direction and partially interlock.
  • the perforated screen 10 is matched to both comminution rollers 5, 6, arched twice.
  • the feed chute 1 has two opposite rigid side walls, which stand up perpendicular to the comminution roller 5 and optionally widen upwards.
  • the two other side walls 2, 3 extending parallel to the shredding roller 5 are arranged in their upper region to be pivotable about axes 4, 9 and end at the bottom near floors 8, 7 curved in a circular arc, which extend on both sides of the perforated screen 10 and close the feed chute 1 downwards .
  • the bottom 8 assigned to the pivotable wall 2 is lower than the bottom 7 assigned to the pivotable wall 3, so that the wall 2 pivots from the side towards the shredding roller 5.
  • the circular arc of the base 8 runs approximately through the axis of the comminution roller 5.
  • the pivoting range of the wall 2 is approximately symmetrical to a vertical plane and the angle is approximately 40 ° to 50 °.
  • the floor 7 assigned to the second pivotable wall 3 begins essentially above the comminution roller 5 in FIG. 1, approximately in an extension of the circular arc of the floor 8, the pivoting range and the pivoting angle of the wall 3 corresponding approximately to those of the wall 2.
  • the two walls 2, 3 are preferably coupled to one another, as indicated schematically by the number 11, and are pivoted back and forth by a drive (not shown).
  • the material lying on the floor 8 above the size of the comminution roller 5 is pressed by the wall 2 against the roller 5 and crushed until it can pass through the perforated screen 10, the material above being able to pass thanks to the parallel pivoting of the wall 3 is moved. According to FIG. 3, this material then falls down during the swiveling back, so that it is crushed in the next swiveling phase according to FIG. 2, and further material can slide down.
  • the pivotable wall 3 is not absolutely necessary, since it can also be rigid if it rises sufficiently inclined to the outside, so that the material is not pinched, but can dodge upwards and automatically slip back again.
  • a rigid wall it could lie, for example, in a tangential plane on the circular arc of the base 8 in the axis of the comminution roller 5.
  • Another conceivable embodiment also shows the movable wall 3 in the same arrangement as the wall 2, that is to say also pulled down to the side next to the comminution roller 5, so that the bottom 7 is approximately equal to the bottom 8.
