Definitions

  • the invention relates to a comminution machine according to the preamble of claim 1.
  • Such a shredding machine is known from DE-A-25 16 014 with a rotatably drivable rotor mounted within a housing, equipped with shredding elements, and two impact mechanisms facing the rotor, which are mounted in frames independent of the housing, both impact mechanisms about horizontal axes in one Position can be pivoted outside the housing, the lower impact mechanism being mounted by swinging, the upper one assumes an approximately horizontal position after pivoting out.
  • both impact units it is not possible to pivot both impact units completely independently of one another out of the housing into an approximately horizontal position outside the housing, so that all the impact elements can be quickly and easily replaced without danger.
  • a crushing machine is also known from AU-B-448 539, in which the impact device is arranged in a housing part which can be opened by approximately 30 °.
  • the housing part cannot be folded out of the housing into an approximately horizontal position. The accessibility of the impact device according to this prior art is therefore also very difficult.
  • DE-C-681 032 shows a comminution machine in which the rear wall can be folded out with baffle plates by only about 25 °.
  • GB-A-2 230 475 shows a crushing housing that can be opened on both ends.
  • the outer end faces are separated in parallel from the central part of the housing by means of a lever system.
  • the invention has for its object to develop the shredding machine described in the generic part of the first claim in such a way that the replacement of all impact elements can be accomplished without great effort, in particular when replacing the impact elements, the safety of the operator (s) with regard to a possible accident risk is guaranteed becomes. Furthermore, it should be possible to replace the baffle elements more quickly and therefore more cost-effectively than in the prior art, in order to reduce the downtime of the comminution machine in a not inconsiderable manner. Finally, the accessibility of the components in the area of the impact mechanism should be improved and the workflow for exchanging the impact elements should be simplified.
  • the change of the impact elements or impact bodies can be brought about outside the housing without any problems, the exchange being approximately in the horizontal position Impact elements or impact bodies can be carried out. Because the impact elements or impact bodies to be exchanged are no longer provided inside the housing, but outside the same, the risk of accidents during replacement is significantly reduced, especially since no operator has to enter the housing to remove the relatively heavy impact elements or impact bodies. reposition.
  • the respective rocker is preferably divided into an upper and a lower area, the upper area receiving the impact mechanism and the lower area being pivotable relative to the housing about a horizontal axis.
  • the pivoting process is such that the wall section in its lower region can be pivoted about an axis that also runs horizontally.
  • the swiveling movement can be brought about by at least one adjusting device, in particular a hydraulic cylinder, which acts on the one hand on a pivot point of the rocker arm or a pivot point on the rear wall area, or on the other hand by means of an exchangeable cylinder which can optionally be fixed at one or the other pivot point.
  • the selection of the adjustment device and its design should be made dependent on the respective application.
  • the impact crusher 1 shown in FIG. 1 and designed as a comminution machine includes a housing 2, a front housing region 3 and a rear housing region 4.
  • a rotor 6 equipped with comminution elements 5 is rotatably driven in the housing 2.
  • the impact crusher 1 according to FIG. 1 is shown here in the closed state.
  • the impact mechanism 7 is suspended within a frame 9, which is only indicated in this figure, so that it can pivot about a horizontal axis 10, the frame 9 being locked relative to the housing 2 by means of a bolt 11, which is only indicated.
  • an adjusting device 12 for the impact mechanism 7 is also provided, by means of which the impact mechanism 7 and thus the impact elements 8 can be advanced in the direction of the crushing elements 5.
  • the frame 9 includes an upper rocker area 13 and a lower rocker area 14, the frame 9 simultaneously being a partial area the rear wall 15 forms.
  • the impact mechanism 16 of the rear housing area 4 is also provided with impact elements 17.
  • FIG. 2 shows a schematic representation of the impact crusher 1 according to Figure 1 from the outside.
  • the same components are provided with the same reference symbols in order to avoid double mentions.
  • the housing 2, the lower rocker area 14, the rear wall 15, which in this case is formed by a pivotable flap 18, can be seen.
  • the adjusting device 12 and an adjusting device designed in this example as a hydraulic cylinder 19, one end of which is mounted in the lower region 20 of the housing 2 and the free end of which is optionally at a pivot point 21 of the lower rocker region 14 or a pivot point 22 of the further impact mechanism 16 can be determined.
  • the drive shaft 23 of the rotor 6 shown in FIG. 1 is only indicated here.
  • a further hydraulic cylinder 24 is provided on the housing 2 and can actuate the front housing part 3 in the opening direction.
  • FIG. 3 shows the impact crusher 1 according to FIG. 1 in a partially opened state, the same components being provided with the same reference numerals for the sake of simplicity.
  • the frame 9 or its upper rocker area 13 and the lower rocker area 14 can be seen in connection with the impact mechanism 7 and the adjusting device 12.
  • the impact mechanism 16 is still closed in this example.
  • the baffle 16 is provided in its upper region with a recess 25 which, when the baffle 7 is in the extended state, is opposite a through hole (not shown here) in the lower rocker region 14, the bolt 11 indicated in FIG. 1 for the purpose of locking the rocker region 14 with respect to the lower one Impact mechanism 16 can be introduced there.
  • FIG. 4 shows the impact crusher 1 according to FIG. 3 in a schematic illustration, but this time in the fully opened state.
  • the upper rocker area 13 carrying the impact mechanism 7 and the lower rocker area 14 pivotable about a horizontal axis 26 are again shown, the pivoting movement being able to be brought about by means of the hydraulic cylinder 19 shown in FIG.
  • the impact mechanism 16 of the rear housing area 4 which is also swung out, is shown in dashed form, which in this example can be pivoted about the pivot axis 34 by the same hydraulic cylinder 19 as an alternative to the impact mechanism 7 into an approximately horizontal position outside the housing 2.
  • This figure indicates on the one hand the through hole 27 in the lower rocker area 14, which, when the lower impact mechanism 16 is retracted, lies opposite the recess 25 shown in FIG. 3.
  • the front housing part 3 is brought into the illustrated open position by the hydraulic cylinder 24.
  • FIGS. 5a and 5b illustrate on the one hand a partial view of the rear region 4 and on the other hand a partial view of the front housing part 3.
  • the upper part of the rear wall 15 is formed by the flap 18 already indicated in FIG. 2, which in this example is about a vertical axis (not shown) is designed to be pivotable and, after opening the same, clears the way to the fastening elements of the impact mechanism, not shown here.
  • the flap 18 is fastened to the housing 2 by means of screws 28, since the upper rocker area in the retracted state of the impact mechanism 7 is retracted together with the impact mechanism 7 within the housing 2. Also shown is the lower rocker area 14, which remains in the retracted state of the impact mechanism 7 outside the housing 2.
  • a further flap 29 is provided, which is screwed to the housing 2 and, after removal of the same, releases further fastening elements of the impact mechanism 7.
  • the further impact mechanism 16 including fastening elements 35 for the impact elements 17 (FIG. 1) and the drive shaft 23 of the rotor can also be seen.
  • the hydraulic cylinder 19 can be mounted either on the articulation point 22 of the impact mechanism 16 or on the articulation point 21 of the lower rocker part 14.
  • the securing elements 30 only indicated here need only be repositioned for this purpose.
  • FIG. 6 shows again in schematic form a partial view of the frame 9 with the two lower rocker regions 14 and the upper rocker regions 13 in connection with the wall section 31, which connects the transition regions of the rockers 13 and 14 to one another. Also indicated is the horizontal axis 26 about which the lower rocker area 14 can be pivoted relative to the housing 2.
  • the impact mechanism 7 mounted in the upper rocker area 13 is only indicated here, the fastening elements 33 securing the impact elements against falling out being marked with crosses.
  • the horizontal axis 10 used to pivot the impact mechanism 7 extends in the upper area of the rocker arms 13. Furthermore, the locking in the form of bolts 11 between the upper rocker arm areas 13 and the housing 2 can be seen.
