Abstract
An apparatus assists in preventing the accumulation of debris in a flow path during the formation of a borehole. In one embodiment, the apparatus comprises a drill head including a drive shaft for driving a drilling element to form the borehole. Preferably, the drilling element includes a passage forming a flow path for debris from the borehole. A carrier positioned adjacent the flow path is connected to at least one agitator connected to the carrier for agitating debris in the flow path. A related method pertains to manufacturing a drill head including an agitator.
Claims20
An apparatus for assisting in preventing the accumulation of debris in a flow path during the formation of a borehole in a face of a mine passage using a drilling element, comprising:
- a drill head including a housing at least partially defining the flow path, said housing including a drive shaft for driving the drilling element to form the borehole, and
- at least one agitator positioned in the housing for agitating debris in the flow path.
A drilling or bolting unit for use with a drilling element for forming a borehole in a face of a mine passage, comprising:
- a drill head having a rotatable drive shaft for driving the drill bit to form the borehole;
- a carrier connected to the drive shaft;
- and
- at least one agitator connected to the carrier, the at least one agitator for agitating debris in the flow path.
An apparatus for assisting in preventing the accumulation of debris in a flow path during the formation of a borehole in a face of a mine passage, comprising:
- a drill head including a drive shaft for driving the drill bit to form the borehole, said drill bit including a passage forming a flow path for debris from the borehole;
- and
- at least one agitator associated with the drive shaft for agitating debris in the flow path.
A method of manufacturing a drill head for assisting in preventing the accumulation of debris in a flow path during the formation of a borehole in a face of a mine passage using a drill bit actuated by a drive shaft, comprising:
- operatively connecting at least one agitator to the drive shaft for agitating debris in the flow path.
