Definitions

  • This invention relates to a toggle block sliding mechanism for a double toggle or single toggle jaw crusher.
  • a jaw crusher is a typical crushing machine that can be used for the primary breaking of rocks as excavated.
  • An example of a double toggle jaw crusher is shown in Fig. 3.
  • Excavated rocks are scooped into a crushing cavity 52 formed between a fixed jaw 5 and a swing jaw 51, and are broken by the impelling force of the swing jaw.
  • the swing jaw 51 is suspended from a swing jaw shaft 53 as a fulcrum, and swings with the movement of a pitman 61, moving up and down with the rotation of an eccentric shaft 6, and the toggle mechanism on either side of the pitman.
  • a double toggle mechanism is formed by a jaw toggle plate 62 that connects the swing jaw 51 and the pitman 61, and a frame toggle plate 64 that connects the pitman 61 and a toggle block 63.
  • a safety device as a guard against uncrushable objects, and an adjustment device to adjust the gap between the fixed jaw 5 and the swing jaw 51, thereby controlling the degree of crushing, are set on the frame toggle plate side.
  • This gap width adjustment device slides the toggle block 63 back and forth, and by means of the frame toggle plate 64, the pitman 61, and the jaw toggle plate 62, adjusts the forward and backward position of the swing jaw 51.
  • a conventional toggle block 63 The sliding mechanism of a conventional toggle block 63 is shown in Figs. 4 and 5.
  • the toggle block 63 is sandwiched, using a wedge 82, between an upper support member 8 and a lower support member 81 affixed like shelves to a machine frame 7.
  • toggle block 63 During normal crushing operation, the toggle block 63 remains fixed. To adjust the cavity or gap width, bolts 83 are removed and the wedge 82 is pulled out, whereupon the freed toggle block 63 is moved back or forth using a hydraulic jack 9. Once adjusted to the desired gap, the wedge 82 is re-inserted, and the bolts 83 are tightened.
  • a single jaw crusher has neither a pitman 61 nor a jaw toggle plate 62, and the eccentric shaft 6 serves a dual function as the swing jaw shaft 53.
  • the object of this invention is to provide a toggle block sliding mechanism for a jaw crusher which enables the position of the toggle block to be adjusted quickly and easily.
  • This invention provides a sliding mechanism for the toggle block of a jaw crusher, comprising a toggle block supporting one end of a toggle plate connected at the other end to the bottom end of a swing jaw; wherein the toggle block comprises an upper block and a lower block, joined by an elastic body, sandwiched between an upper support member and a lower support member that are joined to the machine frame, the toggle block being slidable back and forth with the application of an external force.
  • this invention is effective because, unlike the conventional mechanism, bolts and a wedge need not be removed and then re-inserted with each adjustment, enabling the position of the toggle block to be adjusted quickly and easily.
  • Fig. 1 shows the sliding mechanism of a toggle block 1 which supports one end of a frame toggle plate 64 of a double toggle jaw crusher.
  • the toggle block 1 supports the jaw toggle plate.
  • the toggle block 1 is a steel block, divided into an upper block 11 and a lower block 12. Grooves are carved, at identical positions, into the bottom face of the upper block 11 and the top face of the lower block 12 to accomodate elastic bodies 13, 13 that expand and compress vertically.
  • the elastic bodies maintain the required gap between the bottom face of the upper block 11 and the top face of the lower block 12, and keep the two bodies parallel.
  • a coil-shaped or pine needle-shaped spring, a rubber body, or other material of suitable elasticity can be used as the elastic body 13. During crushing, the force of the swing jaw acting through the frame toggle plate 64 acts upward on the toggle block 1, therefore the elastic bodies 13, 13 need not be of a strength to resist the swinging force.
  • An upper sliding liner 14 and a lower sliding liner 15, each of low frictional resistance, are bonded to the upper surface of the upper block 11 and the lower surface of the lower block 12, respectively. These liners facilitate the sliding action of the toggle block 1, and bear the erosion caused with sliding.
  • An upper support member 2 and a lower support member 3, each made of steel, are affixed like shelves and separated by a specified distance, onto the machine frame.
  • the upper support member 2 has a horizontal upper sliding face 21, and the lower support member 3 has a lower sliding face 21 that is parallel to the upper sliding face.
  • the distance betweeen the two sliding faces is set to be equal to the depth of the toggle block 1.
  • the elastic bodies 13, 13 are compressed to sandwich the toggle block 1 between the upper sliding face 21 and the lower sliding face 31.
  • the natural tendency for the compressed elastic bodies 13, 13 is to expand, the force of which causes the upper sliding liner 14 and the lower sliding liner 15 to press and be clamped firmly against the upper sliding face 21 and the lower sliding face 31, respectively.
  • a device for applying an external force is attached to the toggle block 1 to enable it to slide back and forth.
  • a cylinder 4 can be connected to the back face of toggle block 1, wherein contraction and expansion of the cylinder will enable the toggle block to slide.
  • the cylinder 4 is made to expand or contract, wherein the synergistic action of the sliding action of the upper and the lower sliding liners 14, 15 of low frictional resistance, and the release of the toggle block as the elastic bodies 13, 13 contract, enable the toggle block 1 to slide easily.
