  • buckets are known which comprise an outer casing, configured for the collection of aggregate, and inside which are mounted crushing means for crushing the collected material.
  • bucket is intended to indicate as a whole any device arranged and intended to be hooked onto the free end of an arm of an operating machine.
  • the crushing means arranged in the casing typically comprise a pair of jaws facing each other, one movable with respect to the other for compressing and crushing the material present between same.
  • the operation of crushing the aggregate involves general wear of the members in contact therewith. Such wear is particularly evident in the area of the bucket corresponding to the crushing means, since it is precisely in this part that the bucket must encounter the high compression and shearing stresses exerted on the aggregate by the action of the jaws. It follows that, besides the jaws themselves, the sides of the casing situated immediately at the sides of the jaws are also subjected to the intense wearing action of the aggregate being crushed.
  • the problem underlying the present invention is that of providing an improved crusher bucket, particularly for crushing aggregate and similar materials, and which is structurally and functionally configured so as to remedy the drawbacks mentioned above with reference to the prior art cited.

  • the plates 12 are suitably produced from wear-resistant material, preferably high tensile steel.
  • the plates 12 are fixed to the sides 11 by means of countersunk screws 13 so as to prevent the screws from hindering the flow of the aggregate or from being damaged by same.
