Abstract
A hammer assembly (1) for breaking, levering and raking material, the hammer assembly includes a hammer (1) and an articulated control linkage (3). The hammer includes: a movable mass capable movement along an impact axis (14), an elongated 5 tool (23) having a longitudinal axis substantially parallel or coaxial with the impact axis(4), a primary pivot (6) attachment point for attaching the hammer (1) to a distal end of an operating arm (2) attached to the carrier for pivotal movement of the hammer (1) about a primary axis (6) orthogonal to the impact axis (14). The control linkage (3) includes first (4) and second linkss (5) for effecting pivotal movement of the hammer (1) about the primary axis (6) in response to movement from a drive attached to the operating arm (2).
Claims21
A hammer assembly for breaking, levering and raking material, said hammer assembly including:
- an impact hammer including:
- a movable mass capable of linear reciprocating movement for impact along an impact axis,
- an elongated tool received within the hammer assembly, said tool having a longitudinal axis substantially parallel or coaxial with said impact axis, said tool having two opposed ends with one end projecting from the hammer assembly to form an operative tool head for use during said levering and/or raking operations;
- a primary pivot attachment point adapted for attaching the hammer to a distal end of an operating arm attached to a carrier for pivotal movement of the hammer about a primary axis orthogonal to said impact axis;
- an articulated control linkage including first and second links for effecting said pivotal movement of the hammer about said primary axis in response to movement from a drive attached to said operating arm,
- said first link being pivotally attachable:
- to said hammer at a first end to form a secondary pivot axis parallel to said primary axis,
- at a second end to said drive forming a tertiary pivot point axis and
- to said second link,
- said second link being pivotally attachable
- at a first end to the operating arm forming a quaternary pivot axis parallel to said secondary and tertiary axes,
- at a second end to said second end of said first link and
- at a second end to said drive,
- characterised in that;
- said primary, tertiary and quaternary pivot axes are all located on an opposing side of said impact axis to said secondary pivot axis, and
- said first link includes a pair of arms, spaced apart to receive the hammer therebetween.
A control linkage attachable to a carrier and an impact hammer for breaking, levering and raking material,
- said hammer including:
- a movable mass capable of linear reciprocating movement for impact along an impact axis,
- an elongate tool received within a hammer assembly, said tool having a longitudinal axis substantially parallel or coaxial with said impact axis, said tool having two opposed ends with one end projecting from the hammer assembly to form an operative tool head for use during said levering and/or raking operations;
- a primary pivot attachment point adapted for attaching the hammer to a distal end of an operating arm attached to the carrier for pivotal movement of the hammer about a primary axis orthogonal to said impact axis;
- characterised in that said control linkage includes a first link for effecting said pivotal movement of the hammer about said primary axis in response to movement from a drive attached to said operating arm, said first link being pivotally attachable:
- to said hammer at a first end to form a secondary pivot axis parallel to said primary axis,
- at a second end to said drive forming a tertiary pivot point axis, and
- to a second link, pivotally attached at
- a first end to the operating arm forming a quaternary pivot point axis parallel to said secondary and tertiary axes, and
- at a second end to said drive
- wherein said first link is attachable at said second end to said second end of said second link such that said primary, tertiary and quaternary pivot axes are all located on an opposing side of said impact axis to said secondary pivot axis and said first link includes a pair of arms, spaced apart to receive the hammer therebetween.
A carrier having an articulated operating arm attached to an impact hammer assembly for breaking material, said hammer assembly including:
- a hammer including:
- a movable mass capable of linear reciprocating movement for impact along an impact axis,
- an elongate tool received within the hammer assembly, said tool having a longitudinal axis substantially parallel or coaxial with said impact axis, said tool having two opposed ends with one end projecting from the hammer assembly to form an operative tool head for use during said levering and/or raking operations;
- a primary pivot attachment point attached to the hammer and to a distal end of the operating arm for pivotal movement of the hammer about a primary axis orthogonal to said impact axis;
- an articulated control linkage including first and second links for effecting said pivotal movement of the hammer about said primary axis in response to movement from a drive attached to said operating arm,
- said first link being pivotally attached to the hammer at a first end to form a secondary pivot axis parallel to said primary axis, said first link being pivotally attached at a second end to both said second link and to said drive forming a tertiary pivot point axis,
- said second link also being pivotally attached at a first end to the operating arm forming a quaternary pivot point axis parallel to said secondary and tertiary axes, said second link being pivotally attached at a second end to said second end of said first link and to said drive at said tertiary pivot point,
- characterised in that;
- said primary, tertiary and quaternary pivot axes are all located on an opposing side of said impact axis to said secondary pivot axis;
- and
- said first link includes a pair of arms, spaced apart to receive the hammer therebetween.
