  • the invention concerns device in a loading and construction vehicle and in particular a device for securing a loader bucket tooth according to the preamble of claim 1, a securing unit according to the preamble of claim 11, a loader bucket tooth according to the preamble of claim 16, and a loader bucket .
  • a securing member is inserted perpendicular to the shovel upper surface.
  • the securing member is comprised of shell-like outer parts and an intermediate resiliently compressible layer.
  • a barb element on the securing member prevents it from sliding out from the pocket.
  • the securing unit By the seat being formed in a retaining channel extending essentially in parallel with a bucket bottom plate, the securing unit will be easily installed as well as protected from loaded material. The influence on the very bucket is also minimized.
  • the width of the seat being less than the width of the secure unit, in its unloaded state, secure and accurate positioning of the securing unit is ensured.

  • Fig. 2 shows a loader bucket tooth in a process of being applied to a front edge of a loader bucket
  • Fig. 3 shows a securing unit in an active position with parts of a tooth in phantom for better visualization
  • Fig. 4 shows a securing unit in greater detail
  • Fig. 5 shows a side view of a loader bucket tooth according to the invention.
  • the loader bucket 1 in Fig. 1 is intended for loading abrasiv material such as rock fragments, ore etc.
  • the bucket 1 is provided with a set of teeth 2 - 8 covering the entire front edge with side teeth 2, 8, straight middle teeth 3, 4, 6, 7 and a slightly pointed centre tooth 5. All teeth have the same arrangement for securing them to the bucket .
  • Teeth are applied to the front edge of the loader bucket bottom plate 9 and in the shown embodiment there are side edges 12 and 13 that comprise forward extensions of loader bucket side plates 10 and 11 respectively. In a modified embodiment, teeth corresponding to the teeth 2 - 8 might be positioned also on the side edges 12 and 13 respectively.

  • the securing unit is adapted to secure the tooth 5 to a front edge 31 of the bucket by providing a tightening action against a retaining element 16 which is fastened by e.g. welding and projects upwardly from the plate including the front edge 31.
  • the securing unit 17 is shown positioned with one side against a surface of the retaining element 16 and the other side against two spaced apart side members being parts of the rear upper part of the tooth.
  • a seat 32 for accommodating the securing unit 17 is comprised of recesses in the retaining channel 18 in such a way that four abutment surfaces 26 securely hold the securing unit 17 in place.
  • the securing unit is pressed into the seat 32 inside the retaining channel 18 via an opening 27 which is outwardly widening (inwardly contracting) so as to facilitate insertion of the securing unit.

  • a tightening means 23 which is comprised of screw and nut means extends through holes in the wedge shaped members 24 and 25 and through a hole 22 in the rubber block 21. Tightening of the screw and nut means 23 results in repositioning the wedge shaped members 24 and 25 in such a way that the locking elements 19 and 20 are urged apart in order to achieve a tightening action to elements positioned on the outside of the locking elements 19 and 20.
  • Fig. 5 shows the centre tooth 5 in a side view showing the rear upper part 15 with the retaining channel 18 and a bucket edge receiving groove 30 for receiving the front edge of the bucket.
  • the tooth 5 has a hook like projection 29 which in operation engages under the plate forming the front edge of the bucket .
  • Grooves are provided longitudinally and transversely on the upper and front sides of the tooth 5, for facilitating the sliding movement of the tooth through the material to be loaded.
  • the invention can be modified within the scope of the following claims.
  • the securing unit can be modified such that only one of the locking elements has inclined surfaces so as to co-operate with wedge shaped members having an inclined surface on one side only.
  • the rubber block 21 in Fig. 4 can be exchanged for other resilient elements, including spring acting metallic elements, and can be free with respect of the locking elements.
  • the teeth can be shaped differently, for example such that the teeth of the bucket are spaced apart as is normal with respect of digging buckets.
  • the shape of the retaining channel and the seat for the securing unit can be different, for example without the abutment surfaces even if the solution with at least two abutment surfaces is preferred.
  • the retaining channel does not have t be outwardly widening.
  • the inverted solution is, however, within the frame of the invention, i.e. e.g. a solution wherein on the bucket is fixed a sleeve-shaped retaining housing with a receiving channel for a hook-shaped portion with a reaining element on the rear part of the tooth.
  • the seat will in that case include i.a. sidewadly positioned abutment surfaces on the retaining housing which is fixed (preferably welded) to the bucket.

Abstract

La présente invention concerne un dispositif destiné à fixer une dent de godet chargeur (2 - 8) sur le bord avant (31) d'un godet chargeur (1). Ladite dent comprend une partie supérieure arrière (15), en position d'utilisation sur un godet, qui forme, avec un élément de retenue (16) fixé de manière à s'étendre depuis l'intérieur d'une plaque de godet, un support (32) destiné à recevoir une unité de fixation (17) pourvue de deux éléments de verrouillage (19, 20) pouvant se séparer en vue de serrer la dent contre le bord avant, lesdits éléments de verrouillage étant reliés par un élément élastique (21). Le support (32) est formé dans un canal de retenue (18) s'étendant surtout parallèlement à ladite plaque de godet. L'unité de fixation (17) comprend deux éléments cunéiformes (24, 25), relativement amovibles grâce aux moyens de serrage (23), qui sont disposés entre les éléments de verrouillage (19, 20) afin de coopérer avec ces derniers et effectuer un serrage. L'invention porte aussi sur un godet chargeur, une unité de fixation et une dent de godet chargeur.
