Definitions

  • the present invention relates to an apparatus for use with an excavator or digger, specifically a bucket apparatus that is attached to the stick or dipper arm of the excavator.
  • the present invention refers exclusively to a bucket for use in mining and large scale excavation, the person skilled in the art will appreciate that the present invention can be applied to smaller buckets and excavator machines.
  • a bucket apparatus for excavation said bucket including an upper section and a lower section, said upper section attached to an excavator machinery arm in use, wherein the upper section and at least one lower section are attached together with attachment means such that the lower section can be detached or removed and replaced with second or further lower sections.
  • the lower section of the bucket apparatus is easily replaceable when worn, therefore reducing down-time and expense of replacing or refurbishing the entire bucket apparatus .
  • the upper section of the bucket apparatus remains attached to the excavator machinery.
  • the lower section is selectively removable from the upper section.
  • the upper section is configured to combine or be connected to lower bucket sections with various shapes.
  • the upper section includes at least a first beam means.
  • the first beam means includes one or more apertures.
  • the first beam means includes a plurality of apertures, said apertures selectively located, configured and/or shaped to accept various types of attachment means.
  • multiple lower sections are available to be connected to an upper section.
  • a plurality of various shaped lower sections are manufactured to fit or combine with an existing upper section.
  • it is more economic to replace a lower section if it becomes worn or damaged, and/or if the type of material being excavated requires a different bucket, than it is to replace an entire bucket.
  • the capacity of the bucket can be selected and/or adjusted by switching or replacing a first lower section with a second lower section of different dimensions.
  • attachment means includes any one or any combination of bolts, pins, screws and/or other such releasable means of attachment.
  • the attachment means includes a pin connection.
  • the pin connection includes at least one longitudinal member that extends through at least part of the upper section and at least part of the lower section in use.

  • at least one of the flange members is bolted or screwed to the longitudinal member.
  • the longitudinal member extends through holes or apertures in the upper and lower members.
  • the bucket apparatus includes at least one back bar means.
  • the back bar means is configured to provide a secure and/or fixed joint location between the upper and lower sections. Further typically the back bar means includes two members.
  • one of the back bar members is located on the upper section and the second back bar member on the lower section.
