摘要： A shredder includes a shredder box and a shredder rotor positioned within an interior of the shredder box. The shredder rotor is rotatable about a rotor axis and has a plurality of rotor teeth. An access door is pivotally moveable between an open position and a closed position, the access door defining a side wall of the shredder box when in the closed position. A shredder comb is positioned at an interior side of the access door and includes a plurality of shredder comb teeth. When the access door is in the closed position, the shredder comb is positioned at a shredding location to intermesh with the plurality of rotor teeth for shredding material input to the shredder box. The plurality of shredder comb teeth are removable and reversible for use in two orientations.

摘要： A reamer for drill string pullback of a horizontal directional drill includes a shaft portion defining a central axis and a first end configured for attachment with a drill string of the horizontal directional drill. A plurality of vanes extend radially from an outer periphery of the shaft, each of the plurality of vanes defining an outer peripheral tooth base surface. On each of the plurality of vanes, a plurality of cutter teeth are individually and removably secured along the outer peripheral tooth base surface thereof, each one of the plurality of cutter teeth including a body and a PDC insert manufactured separately from the body and joined therewith. Each cutter tooth of the plurality is coupled to the respective one of the plurality of vanes by a removable fastener extending at least partially through the cutter tooth and at least partially through the one of the plurality of vanes.

摘要： A horizontal directional drilling method includes operation of a HDD machine to power a drill string terminating at a drill head to create an underground borehole extending at least partially horizontally between an entry point and an exit point. A utility line and a pair of insulated wires are attached to the drill string at the exit point. An observation device is also attached to the drill string, and the observation device is connected with an uphole module via power line communication (PLC) over the pair of insulated wires. The horizontal directional drilling machine performs a pullback of the drill string, with the utility line, the pair of insulated wires, and the observation device connected thereto, back toward the entry point. Data from the observation device are displayed on the uphole module during pullback of the drill string.

摘要： A combination of a pullback adaptor and a drill bit includes a pullback adaptor having a first end, a second end, a body extending between the first end and the second end, and a protrusion extending from the body adjacent the second end. The protrusion has a threaded aperture defining an adaptor mounting axis, and the protrusion defines an annular planar mount surface generally perpendicular to the adapter mounting axis. A drill bit has a body with a steering surface, an aperture extending through the body at the steering surface, and an adaptor mount surface adjacent the aperture. The pullback adaptor is mounted to the drill bit with a fastener that extends through the aperture in the drill bit and into the threaded aperture of the pullback adaptor such that the annular planar mount surface of the protrusion engages the mount surface of the drill bit.

摘要： A horizontal directional drilling machine includes a drill string rotational drive unit having an output member configured to connect with and selectively drive rotation of a drill string, the rotational drive unit including a hydraulic motor. A hydraulic circuit has a configuration that puts the motor in a drive mode to apply torque and a second configuration that puts the motor in a freewheel mode disabled from applying torque. The hydraulic circuit includes a first fluid flow path for connecting the hydraulic motor through a first rotary ball valve to one of an inlet side and an outlet side of a drive pump, and a second fluid flow path for selectively connecting the hydraulic motor through a second rotary ball valve to the other side of the drive pump. In the first configuration, there is no pressure drop across the first and second rotary ball valves.

摘要： A rotary drill bit for use with a horizontal directional drill string. A coupler at a proximal axial end is configured to attach the rotary drill bit to a drill head at a distal end of the drill string. A cutting portion at a distal axial end is provided with a plurality of vanes with respective cutters that operate to cut a hole in earth when the rotary drill bit is rotated about a central axis. The plurality of vanes project radially outwardly from a surface of the cutting portion such that the surface forms respective troughs circumferentially interspersed with the plurality of vanes. A plurality of engagement features is positioned axially within the cutting portion and radially inward of an outer cutting diameter to facilitate attachment of a product pullback device between the plurality of vanes without removing the rotary drill bit, or any portion thereof, from the drill head.

摘要： Shaker assemblies for dewatering slurries are disclosed. The shaker assemblies may include a positioning device which limits movement of the vibratory frame of the shaker assembly relative to a subframe when the vibratory frame is moved from a raised operating position to a lowered position. The positioning device may guide the vibratory frame as it is lowered from the raised position to the lowered position. In some embodiments, the shaker assembly includes a locking device for locking the vibratory frame to the subframe when the vibratory frame is in the lowered position.
