Definitions

  • the invention relates to a crushing machine for material of any kind, for. B. waste, such as household waste and bulky waste or wood, comprising a housing provided in a receptacle for the material, at least one driven shaft, are provided on the crushing tools and arranged in the housing rigid cutting tools as counter tools for crushing tools for crushing the material with the in the preamble of claim 1 specified features.
  • waste such as household waste and bulky waste or wood
  • the comminution tools are known to consist of U-shaped knives lying in a plane perpendicular to the axis of rotation of the shafts and uniformly along and around two substantially parallel and horizontal shafts driven by a motor which can drive the shafts in opposite directions and which have a mutual distance which is slightly greater than twice the distance between the radial outside point of a blade and the axis of rotation.
  • the drive devices are provided between the motor and the shafts.
  • the material is fed to the knives through a shaft arranged above the knives.
  • These knives cooperate with knives fixedly mounted between the shafts on a portion of the frame of the material shredding device as the shafts rotate in opposite directions, thereby moving the cut edge of the sheets at the top of the fixed knives towards each other.
  • the mutual distance between the two waves a fixed distance.
  • the drive means also comprise, as previously known, a suitable transmission for each of the two shafts, a hydraulic motor with adjustable rotational speeds for operating each shaft, an adjustable pump for supplying each hydraulic motor and transmission through which the motor operates the pumps, which transmits the flow reversing the hydraulic motors to rotate each shaft individually forward and backward in accordance with a predetermined sequence.
  • each knife comprises two successively arranged and substantially U-shaped blades, that the radially outer and front parts of the two leaves, seen in the direction of rotation of the cutting movement of the knife are constructed as substantially tangentially oriented wedges, that the distance between the axis of rotation and the wedge of the front blade is shorter than the distance between the axis of rotation and the wedge of the succeeding blade and that the radially outer contour of the succeeding blade substantially a segment of a spiral line around the axis of rotation corresponds.
  • the fixed knives are formed by a prior art cutting table fixed to the bottom of a funnel with at least one set; arranged parallel lower knife, which are separated from each other by openings through the table.
  • At least one rotatable shaft of a drive unit is provided, which shaft is arranged above the cutting table in a direction which extends perpendicular to the lower blades.
  • each knife being provided with a number of teeth and extending partially downwardly into each of its openings in the table.
  • Each opening is wider than the associated upper knife, which is also located near one of the lower knives in the associated opening.
  • the lower knives extend in a direction intersecting the axis of the shaft or a region around it, it being assumed for this embodiment that according to DK 169 378 a cutting table is already known whose plane already extends below the shaft.
  • a set of several blades is arranged on each side of the shaft, the arrangement of which form a V or an inverted V to each other.
  • the respective cutting edges may be curved or wave-shaped.
  • the crushing tools are offset in the axial direction on the shaft to each other or arranged at a different radial distance, and accordingly the teeth are arranged on the rigid cutting tools, which cutters run as a so-called slab.
  • the shaft has discs on which the comminution tools are arranged or formed. These crushing tools work, meshing with the teeth between the spaced-apart rigid cutting tools of the slab.
  • the shaft cheap and dismantle, it has on both sides pins, which are detachably connected to the shaft and possibly form a storage area.
  • the connection can be designed so that it takes place by means of flanges.
  • the housing is made double-walled on the end faces, and between them is a labyrinthine sealing against material outlet provided with a shaft plate provided, which may be conveniently formed by the flanges.
  • the cutting contours of the serrated teeth of the rigid cutting tools can be formed by wear elements z. B. are interchangeable.
  • a shredder according to the invention for household waste, bulky waste or wood consists of a housing 1 with two shafts 2 driven in opposite directions.
  • Discs 2.1 are arranged on the shafts 2 and have comminuting tools 3.
  • These comminution tools are arranged at a distance from each other on the shafts 2 in such a way that, in cooperation with rigid cutting tools 4, which run in the axial direction of the shafts 2 as a slab, they operate in a parallel offset and crush a material 5 fed in via a receptacle 1.2 in a cutting manner.
  • the comminuting tools 3 have, in each case a direction of rotation of the shafts 2 and in their cross section, two cutting areas 3.1, 3.2, which are designed such that the stability of the comminution tools 3 is not jeopardized.
  • An inner cutting area 3.1 detects more material to be comminuted 5 and acts with a relatively small lever arm and an outer cutting area 3.2 detects less material to be shredded 5 and acts with a relatively large lever arm.
  • the contours 3.3 of said cutting areas 3.1, 3.2 in the direction of the axes of the shafts 2 each describe a concentric arc around the shafts 2.
  • the rigid cutting tools 4 have a plurality of saw-toothed teeth 4.2.
  • two mutually perpendicular tooth flanks 4.3 of the teeth 4.2 cooperate with at least one of the cutting areas 3.1, 3.2 in such a way that the respective material 5 is always clamped and notched and cut in its entirety by the available edges of the cutting edges.
  • the comminution tools 3 are arranged radially offset relative to one another on the shafts 2 in the axial direction. Not shown in the figures, the possibility that the crushing tools 3 in a different angular position on the shaft 2, ie axially in the cutting profile, z. B. tapered, are arranged. Accordingly, the teeth 4.2 of the axially extending as a slab rigid cutting tools 4 are to be arranged.
  • the housing 1 is designed according to Figure 1 at the end faces with a double wall 1.1, in which the pins 2.2 or ends of the shaft 2 have a sealing disc 2.4, which forms a sealing labyrinth with the double wall 1.1.
  • the sealing disc 2.4 is formed by the flanges 2.3.
  • a crushing machine according to the invention can optimally meet the increased requirements for the comminution of material of the described types, to which means are provided, which detects the gradient of a parameter of the comminution machine and as a reference variable for the control of the comminution machine is used.
