  • the knife carrier 38 is around pins fixed to the housing 40 pivotable and by means of further screws 42 a traverse 44 in the working position shown in Figure 1 lockable.
  • a perforated screen 46 is arranged on the second counter knife 34, which is partially cylindrical and coaxial with the cutting rotor 22 is.
  • the perforated screen 46 is of suitable support plates 48 worn, which in turn on the front wall 20 of the housing 10 are welded.
  • a third counter knife 50 Seen in the direction of rotation behind the perforated screen 46 is a third counter knife 50 is provided, which by means of screws 52 is attached to a crossbar 54, which is also extends between the side walls 12 and the housing 10 stiffened.
  • the guide wall 56 is at the free end of a feed wall 58 welded at 60.
  • the feed wall 58 in turn has lateral tabs 62 with which they are screwed 64 is attached to the side walls 12.
  • the upper end of the feed wall 58 is aligned with the lower edge a loading window 66, which in the Front wall 20 is provided at the upper end.
  • the front wall 20 has lateral at its upper end Tabs 68, which are mounted on bearing pins 70.
  • FIG. 1 Another tab 72 of the front wall 20 that is behind the side wall 12 is articulated with a piston rod 74 of a double-acting working cylinder 76 connected.
  • the front wall 20 can be made the closed position shown in Figure 1 in a clockwise direction pivoted open position are moved, the perforated screen 46 being lifted off the cutting rotor 22 at the same time becomes. There is therefore access in the open position to the cutting rotor 22, in order to grind the material to be clamped there to solve or to maintain tool 24 or exchange.
  • FIG. 1 At one end of the Shaft 82 is a dashed line in FIG. 1 shown drive arm 84 attached to the rotational test.
  • the Drive arm 84 is connected via a hinge pin 86 Piston rod 88 of a double-acting hydraulic Working cylinder 90 connected, the second end over a hinge pin 92 on the one to be thought of above the drawing plane the side walls 12 is fixed.
  • Two guide walls work with the top of the slide 78 94 together in sliding play, which are equally curved and spanned essentially the entire width of the Extend shredder, with its inside However, edges leave a slot through which the swivel arm 80 is passed through.
  • the lower ends the guide walls 94 bound together with the lower one End of the feed wall 58, a passage opening 96 for shredding material, which over the loading window 66 is placed in the shredder and over the feed wall 58 under gravity down slips.
  • the feed wall is 58 at an angle of about 45 ° to the horizontal employed. So you have a high angle of inclination the feed wall, so that plastic materials with relatively high coefficient of friction due to the Gravity safely to the lower end of the feed wall 58 be directed.
  • the lower end of the feed wall 58 ends just above the Path that passes through the top of the slider 78.
  • An end wall 98 of the slide 78 is bent so that you get two halves of the bulkhead, which are essentially tangential to the clear contour of the cutting rotor 22 run when the slide 78 in its shown in Figure 1 foremost end position.
  • top, bottom and end wall 98 of the slider 78 occupied with low strips 100, which in practice is about 5 cm wide and can have a height of about 0.5 cm.
  • the strips 100 prevent X-ray films or other flat material to be shredded over a large area against the outer surface of the slide Lay 78 and adhere to it.
  • the slider 78 is not in any position however, the angle between the direction of movement of the Front wall 98 and the level of the feed wall 58 smaller than 45 °. In this way it is ensured that what is to be shredded Good with a large one perpendicular to the plane of the feed wall 58 standing motion component of the End wall 98 of the slide 78 is detected.
