Definitions

  • the invention relates to a housing for a shredding machine, as it is e.g. is used in a plant for shredding recyclable waste.
  • the invention has for its object a housing
  • housing parts joined horizontally at least in one plane, at least one of which can be pivoted out via at least one pivot point,
  • this is achieved in that at least parts of the wearing parts are fastened to the housing by means of screws provided on the respective wearing part and form zones of different states corresponding to the wear in the shredding process in such a way that around the rotor on the side walls of the housing, the wearing parts are compared with the other wearing parts wear-resistant properties are attached and thus the entirety of the features in their structure, their shape, their material composition and / or their mutual assignment lead to a coordinated wear behavior of the housing and the rotor and approximately uniform maintenance intervals are realized.
  • an upper housing part has a continuous, edged, thick plate
  • a middle housing part between the top grate and rotor on the side walls is equipped with wear parts that are more wear-resistant than the first-mentioned wear parts, and there is an area around the rotor on the side walls of the middle housing part and a lower housing part with respect to the latter Wear parts in turn wear-resistant wear parts.
  • the invention thus advantageously creates differentiated wear zones that are matched to the wear behavior.
  • FIG. 2 shows the upper part of the housing according to FIG. 1.2
  • Fig. 3 with the upper part of the housing a) swung-out cover of the top grate and b) swiveled-in cover of the top grate,
  • Fig. 4 the housing that can be swung open three times a) in the basic position, b) with the upper and middle part pivoted out and the rotor mounted on the lower part, c) pivoted out like b), but with the rotor lifted out, attached to the middle part, d) with the upper part pivoted out, and e ) as a partial view of d),
  • FIG. 5 is a partial perspective view of the lower grate with a lateral upstand to an inactive wear part and a corresponding hammer as an active wear part
  • Fig. 7 is a partial view of FIG. 1.2, in particular with the anvil and the associated clamping device and
  • Fig. 8 shows the storage of the rotor.
  • FIG. 1.1 a housing 1 with an upper part 3.1, which can be pivoted by means of a device 10 via a fulcrum 5, is shown together with a continuously bent plate 3.2.
  • a housing middle part 6 can be pivoted with the device 10 via the pivot point 8.
  • the rotor 32 shown is supported by a bearing 35 fastened to a support 36 by means of prestressing elements 37.
  • an upper grate 20 shown in FIGS. 1.2, 2, 3, 4e is attached in the upper housing part 3.1.
  • the upper housing part 3.1, the middle housing part 6 and a lower housing part 9 - forming the housing 1 - are locked together. Used goods of the comminution in the housing 1, not shown, are placed in a feed device 2, which is not explained in detail.
  • the functional unit housing 1 with rotor 32 takes over in a tried and tested manner the principle of such an arrangement of the bearing 35 which has been used by the applicant since 1990 and which permits a relative movement of the rotor 32 in relation to the bearing 36 if solid parts of the abandoned old goods which are difficult to comminute into the Shredder come up.
  • prestressing elements 37 are inserted between supports 36 and 35, which e.g. may consist of disc springs and fastening screws, not specified, or of hydraulically prestressed fastening elements previously used by the applicant and not shown.
  • FIG. 1.2 The essence of the invention results from Fig. 1.2, in which the housing 1 with the rotor 32, an anvil 14 designed as a counter tool for the hammers 33 (Fig. 1.1) in its bearing 15 with a constant force clamping device 16, e.g. also with hydraulic elements (FIG. 7), furthermore an opening 12 for the introduction of the material to be shredded, the top grate 20 with bars 21, a pivotable ejection door 26 for removing heavy parts, an opposing baffle wall segment 30 and finally the upper housing part 3.1 with side walls 4 , The middle housing part 6 with side walls 7 and the lower housing part 9 with side walls 9 are shown.
  • inactive wear parts (17, 18, 1, 18.2, 19) are fastened by means of these wear parts Screws 31, preferably knurled heads pressed into pre-drilled holes screw, attached to the housing 1 and zones of different states corresponding to the wear in the comminution process are formed such that the wear parts 18.1, 19 are attached to the rotor 32 on the side walls 7, 11 with more wear-resistant properties than the other wear parts 18.2, 17.
  • the housing middle part 6 is equipped between the top grate 20 and rotor 32 on the side walls 7 with wear parts 18.1 which are more wear-resistant than the wear parts 18.2.
  • the area around the rotor 32 is provided on the side walls 7 and 11 of the middle housing part 6 and the lower housing part 9 with wear parts 18.1 and 19 which are more wear-resistant than the wear parts 18.2 (FIG. 7). Practically three zones with different wear properties are formed.
  • the top grate 20 has reinforced rods 21 that are relatively secure against breakout, an upper edge 13 of the opening 12 is coated against wear, a continuous wear segment 24 is inserted between the anvil 14 and a bottom grate 23 according to FIG. 5, and the bottom grate 23 has lateral upturns 25, which attach themselves to the wear parts - here the wear segment 24 - to protect them against the penetration of shredded material.
  • the entirety of these features determining the invention has the uniform effect of designing the operating conditions for the operator of a shredding machine as a result of the uniform maintenance and repair intervals implemented by the invention in a cost-effective and energy-efficient manner and to create optimized spare parts logistics.
  • the housing 1 designed for repair, maintenance and / or care with the functions that
  • the upper housing part 3.1 can be pivoted both by itself and together with the middle housing part 6 with a device 10 (FIG. 4 b), c), d)),
  • the comminution process and the wear behavior can also be regulated in a coordinated manner by the function shown in FIG. 3 of a cover 22 for the top grate 20 which is pivotably integrated in the upper housing part 3.1.
