Definitions
- the invention relates to a crusher, In particular Prall ⁇ breaker, with at least one mounted inside a housing fitted with crushing elements, rotatably driven rotor, and minde ⁇ least one facing the rotor able impact duck having impact apron.
- a crusher In particular Prall ⁇ breaker, with at least one mounted inside a housing fitted with crushing elements, rotatably driven rotor, and minde ⁇ least one facing the rotor able impact duck having impact apron.
- a shredding machine in particular an impact crusher, which has a rotor equipped with crushing elements, at least one impact mechanism equipped with impact elements being stored within the housing.
- at least one portion of the housing can be pivoted about a horizontal axis. Nac part Is to be determined with such a device that it is hardly or not possible to solve the impact elements 1m in the area of the impactor from the outside on the one hand and on the other hand it is problematic to remove the Prallelem te from the inside of the machine. The same applies, of course, to the subsequent refitting of the impact units in reverse Arbelts catfish.
- the object of the invention is to further develop the crushing machine described in the generic part of the first claim so that the exchange of the impact elements can be brought about without great effort, in particular when the impact element is replaced, the safety of the person (s) 1 with regard to a possible accident risk is ensured becomes. Furthermore, the exchange of the impact elements with the St.d.T. can be carried out faster and consequently more cost-effectively in order to reduce the downtime of the comminution machine 1n of not inconsiderable catfish to these catfish. 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 object is achieved in that the locking of the respective impact mechanism or the housing part is removed from the housing and the respective impact mechanism or the housing part 1n is pivoted a position outside the housing and secured there again, the impact elements / body are exchanged or turned, the fuse is then released and the impact mechanism or the housing plate is pivoted back into its starting position and locked again against the housing.
- the exchange of the impact elements or impactors can be brought about outside the housing without any problems, the exchange about 1n horizontal position of the 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 accident during replacement is significantly reduced, especially since no operator has to get into the housing in order to close the relatively heavy impact elements or impact bodies remove or reposition.
- the respective rocker is preferably divided into an upper and a lower area - the upper area accommodating 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 pivoting movement can be brought about by at least one adjusting device, in particular 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 alternating cylinder which can optionally be fixed at one or the other pivot point.
- the selection of the adjustment device or its design should be made dependent on the respective application.
- the invention is illustrated using an exemplary embodiment 1n of the drawing and is described as follows. Show it:
- FIG. 3 Section through an impact crusher with an impact device according to Figure 1 in a partially open state
- 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 shredding elements 5 is rotatably mounted in the housing 2.
- the rotor 6 faces an impact mechanism 7, which includes a plurality of impact elements 8.
- 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 adjustment 12 is also provided for the impact mechanism 7, 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 having a partial rich forms the rear wall 15.
- Another section 16 of the rear housing area 4 is also provided with impact bodies 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 report double answers.
- the housing 2, the lower rocker region 14, the rear wall 15, which in this case is formed by a pivotable flap 18, can be seen.
- the adjusting device 12 as well as an adjusting device in this example designed 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 sub-area 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, which can actuate the front housing part 3 1m opening sense.
- FIG. 3 shows the impact crusher 1 according to FIG. 11 in the 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 adjustment direction 12.
- the further partial area 16 is still closed in this example.
- the partial region 16 is provided in its upper region with a recess 25 which, when the impact mechanism 7 is in the extended state, is opposite a through hole in the lower rocker region 14, not shown here, the bolt 11 indicated in FIG. 1 for the purpose of locking the rocker region 14 can be introduced there relative to the lower partial area 16.
- FIG. 4 shows the impact crusher 1 according to FIG. 3 in a schematic representation, but this time in the fully open state.
- the upper swing area 13 carrying the impact device 7 and the lower swing area 14 which can be pivoted 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 partial region 16 of the rear housing region 4, likewise pivoted out, is shown in dashed lines, 1n this example, an approximately horizontal position outside the housing 2 can be pivoted about the pivot axis 34 by the same hydraulic cylinder 19 as an alternative to the impact mechanism 7 1n.
- This figure indicates on the one hand the through hole 27 in the lower rocker section 14, which, when the lower section 16 is in the retracted state, lies opposite the recess 25 shown in FIG.
- the front housing part 3 is brought by the hydraulic cylinder 24 into the open position shown.
- FIGS. 5a and 5b illustrate on the one hand a partial view of the rear area 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 indicated in FIG. 2, which in this example is not more important shown vertical axis is pivotable and opens the way to the fasteners of the impact mechanism not shown here after opening the same.
- the flap 18 is attached to the housing 2 via screws 28, since the upper rocker area 1n retracted state of the impact mechanism is retracted within the housing 2 together with the impact mechanism. Also shown is the lower rocker area 14, which remains in the retracted state of the impact mechanism outside of the housing 2.
- FIG. 6 shows, in schematic form, again 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 here in the upper region of the rockers 13. Furthermore, the locking in the form of bolts 11 between the upper rocker regions 13 and the housing 2 can be seen.
