Definitions

  • the present invention is related to cone crushers. More precisely, the invention concerns a hydraulic setting adjustment system of a cone crusher. The invention also includes an arrangement for preventing the rotation of the crushing head of a hydraulically adjustable cone crusher.
  • the adjustment of the setting of the crusher disclosed by the publication is effected so, that the inner and outer part of the upper frame of the crusher, said upper frame comprising substantially two parts, are rotated in respect to each other about the vertical axis, whereby the thread formed between the frame parts makes the frame parts to move in vertical direction with respect to each other.
  • the outer upper frame part is attached to the lower frame of the crusher, the inner upper frame part and the outer crushing tool attached thereto are raised or lowered with respect to the inner crushing tool, for adjusting the crusher.
  • the rotating of the frame parts with respect to each other is usually effected either by means of hydraulic cylinders, as described by the patent publication, or by means of hydraulic motors.
  • the main shaft of the crusher rests via pressure bearing assembly on top of a hydraulic adjustment piston of the adjustment system of the crusher.
  • the adjustment piston is adapted to an adjustment cylinder formed in the frame of the crusher, said cylinder providing a vertical motion of the main shaft, when pressure medium is pumped into it or discharged from it, whereby the setting of the crusher is changed.
  • the main shaft as the support cone are moving in a vertical direction with respect to the frame of the crusher.
  • the lower end of the main shaft also moves in the horizontal direction with respect to the frame of the crusher.
  • a third setting adjustment system known in the art is disclosed in the U.S. Patent no 2 799 456 (Behr).
  • the patent publication also discloses a gyratory crusher, wherein the setting adjustment is provided by raising and lowering the main shaft of the crusher, the crushing head attached thereto and thus also the inner wear part up and down with respect to the frame of the crusher.
  • the solution of the Patent 2 799 456 differs from that of the

  • This kind of an adjustment is also common in the market, especially in connection with big gyratory crushers, and it is well known for those skilled in the art.
  • the solution is, however, very complicated and expensive, and it takes up much space.
  • a forth, less known setting adjustment solution is disclosed in the Finnish Published Examined Patent Application 40674 (Linnola et al).
  • the publication discloses a cone crusher including a hydraulic adjustment system comprised of a cylinder tube surrounding the eccentric shaft and having an annular adjustment cylinder and of a frame of the crusher, the hub portion thereof having an annular extension extending upwards to act as a piston of the hydraulic adjustment system.
  • This solution is also complicated and expensive and takes up much space.

  • the present invention provides the use of a simple anti-spin mechanism for preventing the rotation of the crushing head of the crusher.
  • Figure 1 shows a cone crusher in accordance with one embodiment of the invention as a cross-sectional view
  • Figure 2 shows a cone crusher in accordance with another embodiment of the invention as a cross-sectional view
  • Figure 3 shows a cone crusher in accordance with the embodiment of Figure 2 equipped with an anti-spin device for preventing the rotation of the crushing head.
  • Main parts of the crushers of Figures from 1 to 3 are:
  • the frame of the crusher shown in Figure 1 is formed from two main units: the lower frame 1 and the upper frame 2.

  • the central axis of the inner aperture of the eccentric shaft 8 is with respect to the central axis of the outer surface of the eccentric shaft inclined or parallel on a different axis.
  • the inclination of the inner aperture of the eccentric shaft 8 here means that the central axis of the inner aperture of the eccentric shaft is inclined with respect to the central axis of the outer surface of the eccentric shaft.
  • Bearing bushings 10, 11 can be used between the main shaft 3 of the crusher and the eccentric shaft 8, and between the eccentric shaft and the crushing head 4, respectively.
  • the horizontal crushing forces exerted to the crushing head 4 are transmitted to the frame 1 of the crusher via the main shaft 3, the eccentric shaft 8 and the bearing bushings 10, 11, eventually used between the same.

  • a channel 22 is formed into the adjustment piston 13, the pressure medium being supplied through it to the hydraulic cylinder 12.
  • the channel 22 opens at its lower end to a flexible but torsionally rigid pressure medium hose 6, through which the pressurized pressure medium is supplied to the adjustment cylinder 12 from an external pressure source (not shown).
  • the connection between the pressure medium hose 16 and the adjustment piston can be implemented with a connector allowing the hose 16 and the piston 13 to turn with respect to each other.
  • a combined pressurizing and lubricating device known in the art is preferably used as a pressure source.
  • the pressure medium hose 16 is adapted to the lubricant channel 15 formed inside the main shaft 3.
  • the purpose of the lubricant channel is to supply lubricant oil to the sliding surfaces of the crusher, said sliding surfaces located at least between the main shaft 3 and the eccentric shaft 8, between the eccentric shaft and the crushing head 4, between the adjustment piston 13 and the main shaft 3, on the surfaces of the bearing means 10, 1 1, 17, 18 eventually attached to these, on the surfaces of the dust sealing arrangement 23 and on the surfaces of the gear wheel 9 of the eccentric shaft and the power transmission (not shown).
  • the hydraulic cylinder/piston assembly 12, 13 of the hydraulic setting adjustment system can naturally be arranged, by means of a hydraulic control circuit (not shown) of the crusher, to operate also as a safety device in situations, where some uncrushable material, for example solid metal, gets by mistake into the crushing chamber of the crusher among the supplied material.
  • the hydraulic cylinder-piston-assembly 12, 13 can be arranged by means of the control circuit to operate so, that when uncrushable material gets into the crushing chamber and the hydraulic control system discovers abnormal increase of the hydraulic pressure in the pressure medium space of the setting adjustment system, pressure medium will be released from the setting adjustment system in order to decrease the pressure and to enlarge the setting of the crusher so that the uncrushable material can leave the crushing chamber without causing any damage to the crusher.
  • This kind of an operation is known from the crushers of prior art, having a vertical hydraulic cylinder-piston assembly as a setting adjustment system.
  • FIG. 2 shows a cone crusher in accordance with another embodiment of the invention.

  • FIG. 3 shows a crusher in accordance with the invention equipped with an anti-spin device 30.
  • the function of the anti-spin device is to prevent the rotating of the crushing head 4 together with the rotating motion of the eccentric shaft 8. This is necessary in order to maintain an adequate incidence speed of the sliding faces for making sure that an adequate lubricant film maintains between the surfaces in all situations.
