Resilient excavation bucket, excavation apparatus, and methods of use and manufacture thereof
Abstract:
A resilient excavation bucket for use with a piece of machinery having an articulated arm. The excavation bucket comprises a resilient member and a rigid member. The resilient member has a digging edge adapted to deflect in response to pressure from impact with a material at least as rigid as the digging edge and to return to a substantially non-deflected condition upon release of the pressure. The rigid member is cooperatively associated with the resilient member and has a connection member adapted to pivotally engage a portion of the articulated arm of the piece of machinery. At least one of the resilient member and the rigid connection member at least partially defines a bucket cavity disposed at least partially between the digging edge and the connection member. Additionally, an excavation apparatus comprising a backhoe having an articulated arm and the resilient excavation bucket operatively associated with the articulated arm.
