Definitions

  • the invention is, in particular, concerned with mineral breakers of the type described in our patents GB 2170424, EP 0096706 and EP 0167178 in which mineral is broken by a snapping action.
  • the core or arm is made from an impact resistant cast metal and the sheath or cap is made of a wear resistant material such as a high manganese content steel or a suitable steel alloy depending upon the mineral to be broken.
  • the tooth cap may comprise a clamping face for clamping the anchor member to the core. If the material of the tooth cap tends to deform, ie. cold flow, under repeated impacts, it is envisaged that in accordance with a further embodiment of the invention that the tooth cap is isolated from the clamping abutment between the anchor member and the core.
  • the anchor includes a shank portion integrally formed with said mounting portion, the mounting portion comprising a collar formed on said shank portion, the clamping face being defined by one axial side face of said collar.
  • the clamping means comprises a screw threaded portion formed on said shank portion at an axial location spaced from said collar and a nut located on said screw threaded portion, the nut being arranged to clamp ingly engage against said rear face.
  • Figure 5 is an end view taken in direction V in Figure 3;
  • Figure 7 is a view taken along direction VII in Figure 6;
  • Figure 12 is a side view of the tooth cap tip shown in Figure 12;
  • Figure 16 is an end view of the construction shown in Figure 15 as viewed in the direction of arrow XV;
  • Figure 18 is an exploded side view of the construction shown in Figure 15; and Figure 19 is an end view of a pair of breaker drums including teeth as shown in Figure 15.
  • the tooth cap assembly 20 includes a main body 21 , a tip 22, a rear cover 23 and an anchor 24.
  • the body 21 includes opposed side walls 29, 30 which define opposed sides of the channel shaped recess 28 and an upper wall 32 which defines the bottom of the channel shaped recess 28.
  • opposed side walls 29, 30 are generally planar and upper wall 32 is curved, being preferably part circular in cross-section.
  • the tooth core 11 has opposed outer side walls l ib, l ie and a curved upper outer wall 1 Id.
  • Walls 1 lb, c and d are preferably configured and sized so as to closely lie adjacent to the internal faces of walls 29, 30 and 32.
  • the tooth core 11 is provided with a through bore 40 in which is received the anchor 24.
  • the anchor 24 is in the form of a spigot having a stepped shank 44.
  • the shank 44 includes a relatively large diameter portion 45 and a relatively small diameter portion 46.
  • the through bore 40 is similarly stepped having a large diameter portion 42 and a small diameter portion 41.
  • the large shank diameter portion 45 and bore diameter portion 42 are manufactured to be of substantially the same diameter so as to provide an accurate fit which resists displacement of the spigot radially relative to the bore 40.
  • a tooth cap mounting collar 50 is formed on the large diameter portion 45 and is provided with an accurately machined axial end face 51 which defines a clamping face for abutment against an accurately machined forwardly facing end face 52 formed on the tooth core 11.
  • a nut 56 is received on screw thread 46a and is tightened to abut the rearwardly facing end face 57 of tooth core 11. Tightening of nut 56 places the shank under tension and pulls faces 51 , 52 into clamping abutment and in effect clampingly engages the spigot with the front and rear end faces 52, 57 respectively of the tooth core 11.
  • the spigot is formed from a high tensile steel, preferably by forging, such that a high tensile load can be applied by nut 56. This ensures that the spigot is immovably anchored to the tooth core 11 and will remain so during use when the tooth construction will be exposed to repeated high impact forces.
  • FIG. 14 A modification to the anchor 24 and tooth core 11 is illustrated in Figure 14 whereby the anchor 24 and core 11 are adapted to co-operate with one another in order to prevent rotation of the anchor 24 within bore 40.
  • the leading face of the tooth core 11 is provided with an annular projection 111 which is accurately machined to defme a diametrically extending recess 112.
  • the rearwardly facing face of the collar 50 is also accurately machined to define a pair of spaced shouldered recesses 114 which defme therebetween an axially projecting projection 115.
  • cap assembly 20 is securely prevented from movement relative to the core 11 about the axis of the bore 40.
  • the main body 21 includes a circular recess 60 formed in end wall 33 in which collar 50 is located when the main body 21 is seated upon the tooth core 11.
  • the main body 21 is provided with a series of openings 62 which as shown in Figure 1 overlie the collar 50.
  • the openings 62 enable the body 21 to be fixedly secured to the collar 50 by suitable fixing techniques such as welding.
  • the wall 33 is provided with a groove 80a ( Figures 4 and 7) to facilitate welding of the collar 50 to the inside of wall 33.
  • a tooth cap tip 22 is located on the front end of the main body 21.
  • the tip 22 has an internal face 70 which in use is in abutment with the external front face 72 of main body 21.
  • a locating rib 73 projects rearwardly from the lower region of face 70 and is received within a cooperating recess 76 formed in the lower region of face 72 of body 21.
  • a flange 77 protrudes rearwardly from the upper region of internal face 70 and extends over the upper region 74 of main body 21 , preferably as shown in Figure 1 , by a distance sufficient to cover openings 62 located in the upper region of the main body.
  • the upper region 74 is recessed to accommodate flange 77.
  • the flange 77 has an internal face 78 which is seated upon the upper region 74 so that, in use, impact loadings on the flange are transmitted to the main body 21.
  • the internal face 70 of the tip 22 is provided with a recess 90 into which shank portion 85 projects to provide additional support for the tip 22.
  • the cover 23 is fixedly secured to the main body 21 by suitable fixing techniques, such as welding.
  • suitable fixing techniques such as welding.
  • Such fixing prevents the cover 23 from loosening on the screw thread 46a and also fixedly and immovably connects the rear end of the main body 21 to the rear end of the anchor 24. Accordingly, with such an arrangement, the main body
  • the tooth cap main body 21 in effect defines a bridge extending between the front and rear ends of the anchor 24 and is immovably secured at respective ends thereto. Since the anchor 24 is immovably secured to the tooth core 11 , the tooth cap main body 21 is similarly immovably secured to the core 11.
