Definitions

  • the invention relates to a jaw crusher with a stationary supported jaw and a counter jaw which can be driven relative to this jaw about a pivot axis for reciprocating movement, in which the driven counter jaw is moved by an eccentric shaft via toggle levers.
  • jaw crushers of this type which are state of the art as toggle levers or double rocker crushers
  • medium and large pieces of rock can be mechanically crushed in a simple and effective manner.
  • the use of toggle levers for the drive allows the movable jaw to be curved and to work with a pivot point that is relatively high and close to the line of symmetry of the breaking angle with a minimum of friction during the breaking process and a large stroke in the area of the breaking jaw. In this way, the surface wear is evened out and the crushing jaw wear is reduced.
  • the center of gravity of the rocker can also be chosen so that the required idle power is reduced.
  • the pressure component can be adjusted in such a way that it is directed downwards, which causes the rock to be crushed to be drawn in well and the throughput rate is increased.
  • the inexpensive and constant kinematics enables the user to approach an extended toggle lever and the associated high refractive powers with low drive power, which also has advantages for the design of the overload protection.
  • This construction also ensures a constant stroke of the crushing arm and thus a constant return spring setting.
  • the entire toggle mechanism can be designed with closed oil circulation lubrication, which can reduce the bearing friction and in turn drive power can be saved. Due to the design, light crank drives can be used, which at the same time lead to a reduction of the dynamic forces on the foundation.
  • the invention now aims to influence the stroke and the refractive forces in a particularly simple manner in such a known construction in order to be able to take into account different rock properties with the same jaw crusher construction.
  • the design according to the invention in a jaw crusher of the type mentioned at the outset is that the mounting of the eccentric shaft is displaceable and can be fixed in the displacement position. In this way it is possible to move the toggle levers into a more or less extended position, the stroke being relatively small when the toggle lever is in a more extended position. With a relatively small stroke, the forces are correspondingly greater and the crusher is advantageously suitable for hard and brittle rock.
  • the gap width only has to be adapted to the respective conditions again by appropriate adjustment of the stationary counter jaw.
  • the design according to the invention can be such that the mounting of the eccentric shaft is fixed eccentrically on a rotatable circular disk.
  • the eccentricity of the bearing body is advantageously dimensioned so that it amounts to 10 to 40% of the eccentricity of the drive shaft.
  • the drive of the eccentric shaft can be ensured in a simple manner in that the eccentric shaft passes through the circular disk and carries a pulley for the drive.
  • the drive motor of the eccentric shaft is advantageously adjustable relative to the axis of the eccentric shaft for the various settings of the bearing body eccentric or the circular disk.
  • a structurally particularly simple configuration results if the circular disk has bores on its circumference for fixing the rotational position by means of bolts or screws.
  • FIG. 1 shows a schematic side view es double toggle jaw crusher
  • Fig. 2 shows a first setting of the eccentric shaft for breaking soft rock
  • Fig. 3 shows a medium setting for average rock conditions
  • Fig. 4 shows a further adjustment of the eccentric shaft to reduce the stroke and thus to transmit larger forces to the movable crushing jaw .
  • a double toggle jaw crusher 1 is shown, on the housing 2, a bearing 3 for a bearing axis 4 is fixed.
  • a movable crushing jaw 5 is swingingly suspended on the bearing axis 4 and is driven by toggle lever 6 via an eccentric shaft 7.
  • the toggle lever 6 are hiebei of a exzentri the - at least partially encompassing the bearing shell's shaft stubs 8, wherein said transfer member is indicated by 9 and is supported against a fixed compression spring 10 degrees.
  • the toggle levers 6 are moved alternately into a more extended and an angled position, which results in a stroke of the crushing jaw 5 in the direction of the double arrow 11.
  • the breaker gap 12 can be adjusted by appropriate adjustment of the stationary counter jaw 13.
  • the crushing jaw 13 is fixed via a releasable pull rod 14 and spacer elements 15 can be interposed according to the desired breaker gap 12.
  • the forces are supported in each case via spherical bearings 16 in the crusher housing.
  • the crushing surfaces are equipped with correspondingly wear-resistant insert parts 17.
  • a return spring 18 is provided, which is also supported on the housing 2.
  • the wear surfaces 17 can be exchanged in a simple manner and the fixing of one of the two wear surfaces is indicated schematically by a pull rod 19.
  • a rotatable disk 20 is secured to the housing in the respective rotational position, for which purpose bores 21 are provided on the circumference of the disk.
  • the rotatable disc 20 has an eccentric bore 22 for receiving the bearing body 23 of the eccentric shaft 7.
  • a bearing body eccentricity which overall leads to a large stroke of the schematically indicated toggle levers 6. Such a large stroke naturally transmits smaller forces and is particularly suitable for breaking soft rock.
