Abstract
An excavation apparatus includes a supporting linkage mountable to a vehicle, and a rotary spindle operable to drive a coring element about a cutting axis. The supporting linkage supports the rotary spindle and is operable to displace the rotary spindle relative to a ground surface. The supporting linkage can lower the rotary spindle to a deployed position and raise the rotary spindle to a stored position. The cutting axis can be maintained in a vertical direction in the deployed and stored positions. The rotary spindle can move relative to the supporting linkage about a hinge axis. The hinge axis can be generally parallel to the vertical direction.
Claims22
An excavation apparatus, comprising:
- a supporting linkage mountable to a vehicle;
- and
- a rotary spindle operable to drive a coring element about a cutting axis,
- wherein the supporting linkage supports the rotary spindle and is operable to displace the rotary spindle relative to a ground surface.
An excavation apparatus, comprising:
- a supporting linkage mountable to a vehicle;
- a vertical supporting member connected to the supporting linkage;
- and
- a rotary spindle coupled to the vertical supporting member and operable to drive a coring element about a cutting axis,
- wherein the vertical supporting member is configured to move relative to the supporting linkage about a hinge axis that is generally parallel to a vertical direction.
An excavation apparatus, comprising:
- a supporting linkage comprising an inner bracket, an outer bracket that is spaced apart from the inner bracket, at least one upper bar that is pivotably connected to the inner and outer brackets, and at least one lower bar that is pivotably connected to the inner and outer brackets;
- a vertical supporting member connected to the outer bracket of the supporting linkage;
- and
- a rotary spindle coupled to the vertical supporting member and operable to drive a coring element about a cutting axis,
- wherein the inner bracket of the supporting linkage is mountable to a vehicle,
- wherein the supporting linkage is configured to lower the vertical supporting member relative to a ground surface to a deployed position, and raise the vertical supporting member relative to the ground surface to a stored position, and
- wherein the vertical supporting member is configured to move relative to the supporting linkage about a hinge axis that is generally parallel to a vertical direction.
