Abstract
A roof removal machine may include an auger assembly at least a first helical auger flight coupled to a central axle, and a plurality of blades coupled to an outer edge of the auger flight. A motor is operably coupled to the auger assembly and configured to rotate the auger assembly about the axle in at least a first direction of rotation. The blade edge of each of the blades is oriented transverse to the first direction of rotation. In some examples, a second helical auger flight is also coupled to the central axle, and the two auger flights may be oppositely-handed with respect to each other, such that roof debris is moved toward a central extraction port.
Claims20
A roof removal apparatus, comprising:
- a vehicle configured to travel across an underlying surface;
- and
- an auger assembly coupled to the vehicle, the auger assembly including
- a central axle defining an axis of rotation transverse to a direction of travel of the vehicle,
- a first helical auger flight having an inner edge coupled to the central axle, such that the first helical auger flight is rotatable about the axis of rotation, and
- a plurality of blades removably coupled to an outer edge of the first helical auger flight;
- wherein rotation of the first helical auger flight about the axis of rotation is configured to cause the plurality of blades to cut into the underlying surface.
A roof removal machine, comprising:
- an auger assembly including a central axle defining an axis of rotation, a first helical auger flight coupled to the central axle, and a plurality of blades coupled to an outer edge of the first helical auger flight, each blade comprising a blade edge and a blade body;
- and
- a motor operably coupled to the auger assembly and configured to rotate the auger assembly about the axis of rotation in at least a first direction of rotation;
- wherein the blade edge of each of the blades is oriented transverse to the first direction of rotation.
