  AT 003 861 U2
The present invention relates to a comminution device for material which can be comminuted by the action of a knife, in particular wood, plastic and cellulose-containing material
Material in which a rotor is equipped with comminution tools, in particular knives, in a housing.



   Comminution devices of this type, which are particularly suitable for comminuting and possibly recycling waste, in particular wood waste, residual wood pieces, plastics and cellulose-containing material, textiles, carpets and rubber tires, are known in the prior art Large rotor materials that are in bale form, such as textile bales, can also be fed into the comminution area. As is known, material in bale form requires much less space during transport and storage than material in bulk, but it has the disadvantage that it contains various non-comminutable foreign bodies that enter the bale material when it is placed Shredding machine are not detectable.



  The disadvantages of this prior art are overcome by the present invention, achieving the advantages described below.



  The bale material and, of course, possibly also material that is not to be shredded in bale form independently reaches the cutting process and

 is crushed. Fixed and bulky parts are shifted by changing the direction of rotation and are further shredded on the opposite side of the shredding machine.



   A built-in sieve, which can be exchanged in the sieve size, guarantees a comminuted product, for example a granulate in a defined particle size
In practice, however, it is inevitable, as already explained above, that various non-comminutable foreign bodies which are present in the comminution machines of the
State of the art can only be laboriously removed by clearing the entire comminution area.



  In the comminution machine according to the invention, on the other hand, when a set maximum torque, in particular pressure torque, is reached, the side wall with counter knife receptacle can be opened, so that the foreign body can be separated out favorably.



  This torque can be set either hydraulically or mechanically.



  This ensures a safe and fast way of working in the company.



  The essence of this present invention will now be further explained with the aid of the enclosed FIGS. 1-3, which represent a preferred exemplary embodiment.

   The same components are identified with the same reference numbers in all figures
Figure 1 shows a vertical section through the subject matter of the invention
The reference number 1 denotes the rotor which carries the chopping knife 2 on its surface.



  The two rotational directions of the rotor are identified by the reference numerals la and 1b. Reference numeral 3 is a clamping part, 4 a fastening and impression screw, 5 a swing-out wall, 6 an upper counter knife arranged at the lower end of the swing-out wall 5 and 7 the Corresponding lower counter knife With the reference numeral 8, the triggering device is identified, which causes the swing-out wall 5 to swing out.



  Reference numeral 9 designates a cylinder with a preload which cooperates with the triggering device 8 in such a way that, after a respective presetting, when the maximum torque is reached, it actuates the triggering device 8 in such a way that it is actuated, for example, by a spring-actuated or hydraulically actuated one Telescopic arrangement 12 causes the swing-out wall to swing out.

 The reference number 10 denotes the material insertion zone and 11 the material discharge zone.



  The principle of the present invention is shown in FIG. FIG. 2 also shows a vertical section of the comminution machine according to the invention. FIG. 3 also shows a vertical section of the comminution machine in the viewing direction pivoted by 90


    

Claims (5)

 Expectations: 1. Comminution device for material comminuted by the action of a knife, in particular for wood, plastic, tire and textile material, according to the principle of rotor comminution, characterized in that at least 1 side wall (5) is designed as a swing-out wall. 2. Shredding machine according to claim 1, characterized in that an upper counter knife (6) and a lower one on the swing-out wall (5) Counter knife (7) are arranged 3. Comminution machine according to claim 1- 2, characterized in that measuring elements are arranged, which cause the pivoting out of the swing-out wall (5) and thus the elimination of non-comminutionable ones Cause foreign bodies.  <Desc / Clms Page number 6>   4. Shredding machine according to claim 1-3, characterized in that a cylinder (9) is arranged with a bias, which cooperates with a trigger device (8) 5. Shredding machine according to claims 1-4, characterized in that a live telescopic arrangement (12) is present, which at Solution of the triggering device (8) automatically causes the pivoting wall (5) to pivot out.
