  • Patent number: 8615906
    Abstract: A drilling bucket adapted to combine with a prime mover vehicle such as an excavator. The drilling bucket includes a floor pivotally combined with the bucket. The floor has an open position wherein collected spoils are emptied from the bucket and a closed position for retaining spoils in the bucket during operation. A release assembly is adapted to securely hold the floor in its closed position until it is actuated to release it to its open position. Some embodiments of the drilling bucket comprise two separate internal cavities. The first cavity is adapted to receive the spoils as the bucket is rotated beneath the ground by the prime mover vehicle. The second cavity is adapted to house portions of the release assembly. The second cavity may serve as a vent which allows air to pass the bucket as the bucket is being raised or lowered in a hole.

  • Publication number: 20090283330
    Abstract: A debris removal device features structural support from an exterior housing that allows more space for debris collection. The debris enters the collection volume from the top to eliminate debris from having to go through a valve. The screen in the device is disposed internally to protect it during handling and running. A variety of external flow diverters are used to direct debris laden fluid into the tool and to keep debris out of an annular space around the tool that could interfere with its removal. The diverters can be actuated by relative movement in the tool or applied pressure to a piston which can inflate a sleeve or orient or misalign paths through brushes for selective bypassing of fluid exterior to the tool.

  • Patent number: 7614463
    Abstract: A flute-wiping auger cleaner has a laterally-shearing shackle, an axial track spaced parallel to the auger; and a traveling carriage on the track for supporting the shackle. The shackle includes a series of angularly-staged wiper blades to project into the flute of the auger and centrally stabilize the blades on the turning axis of the auger. The shackle is biased not only to pressure the wipers inwards towards the auger's cylindrical sidewall but also allow the shackle to open slightly against the force of the bias in event a blade cannot dislodge a difficult clump of fouling material in the flute. In that event, the blade is pushed out and then pressured back in as it rides over the difficult-to-dislodge clump. Spinning the auger causes the blades to travel the length of the helical flute while the shackle travels axially on the track.

  • Publication number: 20080196881
    Abstract: There is disclosed a cleaning tool for use in cleaning ferrous material from a wellbore, a cleaning assembly comprising a plurality of such wellbore cleaning tools, and a method of cleaning ferrous materials from a wellbore. In one embodiment, a cleaning tool (12) is disclosed which comprises a tool main body (19) and a number of magnets (20) mounted for selective movement relative to the main body between deactivated and activated positions. When in the activated positions, the magnets serve for attracting ferrous material present in a wellbore (10), to collect such material during passage of the tool along the wellbore, so that the ferrous material may be returned to surface to thereby clean the wellbore.

  • Patent number: 7032692
    Abstract: Locking elements 3d and 3j are provided at an inner member 3 connected to a kelly bar 1, and a locking element bearing plate 6f is provided at an outer member 6. The outer member 6 includes a cylindrical bucket 7 and a grab bucket 8 housed inside the cylindrical bucket 7. When an excavating tool 2 is in its most contracted state, the inner member 3 is rotated forward to lock the locking elements 3d and 3j at the locking element bearing plate 6f, thereby disallowing relative vertical movement of the inner member 3 and the outer member 6. As the excavating tool is rotated by applying a force to the kelly bar 1 along the lifting direction in this state, an excavating operation can be executed while applying a load smaller than the load of the excavating tool 2.

  • Patent number: 6863136
    Abstract: Apparatus for probing, sensing, testing penetrating and sampling a medium generally includes an actuator (12) for generating vibrations at ultrasonic frequencies and a horn (14) coupled to the actuator (12) for amplifying the actuator vibrations along with a non-rotating coring and drilling bit (16) for penetrating the medium. A bit (16) includes a drill stem (20) attached to the horn (14) and a bore (26) extends through the bit (16), horn (14) and actuator (12) for withdrawal of samples. A free mass (36) is disposed between the horn (14) and the drill stem (20) for oscillating therebetween in response to the actuator vibration for causing migration of medium debris around and through the actuator bore for effectively self-cleaning of the bit (16). The hammering action of the free mass (36) is used for penetration of the medium and for analysis of the medium though the use of spaced apart accelerometers (92 and 94).
