Definitions

  • the invention relates to a stone splitter according to the Preamble of the main claim.
  • a stone splitter is described in EP 443 123 B1, at which uses an eccentric drive consisting of two eccentric wheels exists, which drive with each other via a rack are connected.
  • a lever device engages on one eccentric wheel, the eccentric wheel with a External toothing is equipped. Due to the rotating movement this eccentric wheel, at the same time the Tarund Downward movement of the knife holder takes place now the rack is taken along with the external toothing and the external toothing of the second eccentric drive via the rack rotated. This also affects Area of this second, not directly via a lever device driven eccentric on a pressurization the knife holder down.
  • the invention has for its object a stone splitter the generic type in such a way that a reduction the effort for the hydraulic movement of the Knife holder and a cheaper production allows becomes.
  • the hydraulic pressure generator from a preferably elongated, plastic sleeve closed on all sides, into which a connection nipple is used to supply pressure oil, so that an oil channel is created.
  • an abutment plate is preferably arranged, wherein this abutment plate rests on the top of the plastic cover and the nipple used to supply the pressure oil is passed through this abutment plate, so that the oil pressure on the top facing away from the device Underside of the abutment plate and the associated Inside of the plastic cover is generated.
  • the abutment plate is preferably made of metal or Plastic and the plastic cover made of chloroprene rubber. Chloroprene rubber has a high resistance against oil, is very insensitive to pressure and can Multiples of its size are inflated, making it possible was that the pressure generator according to the invention with 120 bar is operated without the plastic cover, for example 5 mm thick, has been damaged.
  • the hydraulic pressure generator acts on the knife holder on the one hand and is supported by an abutment on the other off, so no additional gear parts are needed to the knife holder to move.
  • the stone splitter shown in the drawing has a frame 1 equipped with a footrest 27 and a pair of wheels 28 can be.
  • the frame 1 carries a knife holder 2 Single cutting 3, the fasteners on the knife holder 2 are set. These individual cutting edges 3 act as Shear cutting.
  • An upper knife holder 5 carries individual blades 6, and the two Single cutting edges 3 and 6 can be used in a common Level to be moved towards each other, in that the knife holder is moved down, in addition the knife holder 5 can be adjusted in height.
  • the knife holder 5 is adjusted in height by adjusting means 7 and 8, which carry a carrier 9, the carries the actual knife holder up and down.
  • a hydraulic pressure generator is located above the knife holder 5 10 arranged, the one hand on one of the knife holder 5 worn abutment plate 23 and on the other hand, d. H. on its back, supported on an abutment plate 24.
  • the feeder of pressure oil takes place via an oil channel 14 and it can be seen that by inflating or inflating the actual Pressure generator 10 now the knife holder 5 after can be moved down.
  • 11 denotes a plastic cover
  • the abutment plate in the illustrated embodiment 12 is arranged from metal.
  • the abutment plate 12 brings about a certain dimensional stability of the pressure generator 10 and continues to produce a more even pressure distribution.
  • Used in the abutment plate 12 is a connecting nipple 13, the can also consist of metal, and the abutment plate 12th is preferably with the top 18 of the plastic shell 11 welded or vulcanized, the bottom 19 of the Plastic sleeve 11 loosely on the underside of the abutment plate 12 is present. This causes that by the Nipple 13 and the oil channel 14 supplied oil between the lower Page 19 and the abutment plate 12 can penetrate and now thereby actuates the hydraulic pressure generator 10, so that it is inflated.
  • the plastic cover 11 preferably consists of a chloroprene rubber and the abutment plate 12 made of metal, however it is entirely possible to also make the abutment plate 12 a correspondingly resistant plastic.
