Definitions

  • the invention relates to a comminution machine, in particular for rejects or demolition parts in the construction industry, according to the preamble of patent claim 1.
  • the object of the invention is to provide a comminution machine which, in particular, precast concrete slabs, such as Floor covering elements, broken down into mineral and ferritic components, whereby the mineral components are obtained as bulk material in a constant grain composition and can be recycled.
  • the aim is to obtain an arbitrary grain size of the comminuted material with simple adjustment of the comminution machine.
  • the feature according to claim 2 is used to readjust the crusher when the hammers are worn.
  • the feature according to claim 3 is used to control the degree of wear of the hammers.
  • the measure according to claim 4 serves for simple adjustment of the rotor when the hammers are worn.
  • the shredding machine consists essentially of a crusher B and a loading device C, the two parts of which are accommodated in a housing D.
  • the loading device consists of a lower, endlessly rotating horizontal feed belt 7 and an endlessly rotating friction belt 1, which is directed obliquely downwards in the conveying direction A against the feed belt 7 and is guided over deflection rollers 13, 14.
  • the feed belt 7 is guided over deflecting rollers 8, 9, the deflecting roller 9 facing the crusher B being driven by a drive shaft 15.
  • the drive shaft 5 is guided in a curved slot 11, the radius of curvature of which passes through the central axis of the crusher B, so that the deflection rollers 14 can be adapted to the thickness of a plate supplied to the crusher B or the like.
  • the shredding machine is intended for shredding plank ceiling panels, which are designated by 39 in FIGS. 1 and 2.
  • hydraulic cylinders 18, 22 are provided which, via a piston rod 19 or 23, a triangular toggle lever 20 or 24, and a link 25 or 4 to the shafts 26 or 5 of the deflection rollers 8 or 9 of the friction band 1 are connected.
  • the crusher B is designed as a rotor, which has a drive shaft 27, which is mounted on its ends projecting on both sides of the housing D, as shown in FIG. 3, in rockers 30, which are each pivotable about a pin 38 fastened in the housing D on the bottom are stored.
  • On the drive shaft 27 are arranged at intervals from each other with this coupled to rotation segment disks 28 (Fig. 4), on which are made of highly wear-resistant cast and largely insensitive to unbreakable foreign bodies 29 are suspended swinging about a pivot axis 31.
  • the disc segments 28 are successively offset in pairs by 90 degrees to one another, the hammers 29 each being suspended between a pair of disc segments.
  • the hammers 29 In the present case, three successive groups are provided, each with hammers 29 offset by 90 degrees, the hammers 29 of all groups lying in the same angular position being aligned with one another in a row.
  • the hammers 29 have a width of approximately 120 mm, two blind disks 33 being provided between each two disk segments 28 in the width of the hammer 29.
  • the successive hammers 29 on the circumference of the rotor, each offset by 90 degrees, are, as shown in FIGS. 5 and 6, each offset by a hammer width in the longitudinal direction of the rotor.
  • the hammers 29 strike each other next to the material to be shredded.
  • the hammers 29 each break one line of the material in steps of four sections in the width of the hammers 29.
  • the floor cover plate 39 rests on an anvil 6, which in the present case Trap has a square cross-section and can be pulled out of the housing and seated on a shoulder 34 of the housing D in its longitudinal direction and rotated about its central axis, so that at least two diametrically opposite edges can be used.
  • anvil 6 when its corner facing the crusher, as indicated by the broken line, is worn, it can be pulled out of the housing D and rotated into it by 180 degrees, so that its diametrically opposed edge of the worn edge is not worn Edge can be used.
  • a similar arrangement is also made for the hammers 29, in that the hammers 29, when their striking edge is worn out, as shown in dash-dotted lines, can be hung between the disk segments 28 offset by 180 degrees.
  • the breaker B is driven by an electric motor 35 via a multi-strand V-belt 36 onto a V-belt pulley 32, which, coupled to the drive, stirs on the drive shaft 27. This sits in curved slots 37 of the housing D, the radius of which goes through the central axis of the pin 38.
  • a hydraulic cylinder 10 provided with a piston 45 is used, which can be pivoted about an axis 12 and is articulated with its piston rod 44 to one of the rockers 30 (FIGS. 1 and 8).
  • the pressure of the piston 45 is in relation to the degree of wear of the hammers 29, so that at the beginning of the piston is in its rear end position and with increasing wear the hammer 29 is advanced in the direction of arrow E (FIG. 8), with it being at the maximum permissible wear of the hammers 29 has traveled its maximum path, which is limited by a nut 42 which is screwed onto a threaded part 43 of the end of the piston rod 44 protruding from the cylinder 10 and is connected to a sleeve 46, for example by welding, which is carried out by a Ring 47 is supported on the end face of the cylinder 10.
  • the orbit of the hammers 29 is indicated with a dashed circle U in the starting position.
  • the permissible degree of wear of the hammers 29 can be adjusted by adjusting the nut 42.
  • the shredding machine works in a shredding of floorboard panels in the following way:
  • the floorboard panels 39 are fed by a loading device, not shown, to the feed belt 7, which brings the floorboard panels 39 up to the friction belt 1, which is set with its front end so that the slot between Friction belt 1 and feed belt 7 at this point correspond to the thickness of the floor cover plate 39, so that as soon as it reaches this slot, it is fed to the crusher B.
  • the friction belt 1 is, as described, infinitely adjustable and runs at the same speed as the feed belt 7.
  • the retracted plank ceiling plate 39 which is thus clamped, is brought into the engagement area of the hammers 29 via the anvil 6. Due to the arrangement described, the hammers 29 produce an uninterrupted cut with a single width, which corresponds to the single width of the hammers 29, thus 120 mm in the exemplary embodiment.
  • the staggered arrangement of the hammers results in a helical machining of the decking slabs.
  • the desired size of the grain of the removed material can be adjusted by adjusting the speed of the crusher and the feed speed of the removed material.
