Definitions

  • the invention relates to a device for splitting stones, which device comprises:
  • Such a device is known for instance from DE-C-198 42 670 in the name of applicant.
  • the hydraulic means are formed here by a bellows which is arranged between the upper blade and the frame, so that the blade is pressed toward the other blade by filling the bellows with hydraulic oil, and a stone can thus be split.
  • the drawback of this device is that the bellows has a short lifespan. The bellows wear due to the heavy use and will begin to tear, whereby leakage occurs and the device becomes unusable.
  • Devices are further known for splitting stones wherein the one blade is pressed to the other blade by means of a single hydraulic cylinder.
  • the drawback of such a device is that the blade cannot adjust itself to the stone for splitting. If the blade comes to lie at only one point on the stone during splitting, the breaking of the stone will proceed in uncontrolled manner and an irregular breaking surface will thus occur.
  • Such a device with only one hydraulic cylinder further has the drawback that, in order to obtain a sufficient pressure force, the dimensions of the single hydraulic cylinder will be large relative to the dimensions of the whole device. This affects the ability to handle the device.
  • the hydraulic means comprise at least two hydraulic cylinders which are in liquid communication with each other.
  • both hydraulic cylinders will then displace the blades toward each other. As soon as a blade comes to lie partially against the stone, one of the two hydraulic cylinders will encounter more counterpressure than the other. The hydraulic cylinder with the least counterpressure will hereby press the other part of the blade further, so that the whole blade comes to lie against the stone and a good contact is thus ensured, thereby resulting in a good breaking surface.
  • the two blades are arranged in blade holders arranged on the frame, wherein the distance between the blade holders is adjustable.
  • Stones of varying thickness can hereby be split with the same device, wherein the stroke of the hydraulic cylinders can remain limited.
  • the hydraulic means comprise a number of hydraulic cylinders placed adjacently of each other and between the frame and a blade holder, the outer diameter of which cylinders is substantially the same as the width of the relevant part of the frame and wherein the number of cylinders corresponds with the whole number part of the quotient of the available length on the frame and the outer diameter.
  • the dimensions of the frame and the blade holders are chosen such that the device is sufficiently strong. If the stone splitter is so designed, a limited space is then left between the frame and the blade holder.
  • each cylinder is chosen such that it corresponds with the width of the frame or the blade holder and as many cylinders as possible are placed mutually adjacently.
  • the available space is hereby used optimally, and the device remains manageable.
  • spring means are arranged for urging apart the blades. These springs ensure that the blades are once again carried apart after splitting of a stone, so that a following stone can be placed between the blades.
  • the blades comprise a number of blade parts arranged mutually adjacently, which blade parts are arranged in spring-mounted manner. These spring-mounted blade parts offset small irregularities on the stone, so that the blade lies even better against the stone for splitting.
  • FIG. 1 shows a device 1 according to the invention.
  • This device 1 has a base plate 2 on which is arranged a lower blade holder 3.
  • a lower blade holder 3 On either side of lower blade holder 3 are arranged two jacks 4 between which an upper blade holder 5 is arranged.
  • the jacks 4 By operating the jacks 4 by means of handles 6, the lower and upper blade holders 3, 5 can be carried toward and away from each other, so that they can be adapted to the thickness of a stone S.
  • Blade parts 7 are arranged in both lower blade holder 3 and upper blade holder 5.
