One or more apparatuses are described for drilling, and related methods. The apparatus can include a mast articulation mechanism supported by a base structure, an elongated mast, and a mast actuator.

A drilling device for geotechnical engineering investigation is provided, including an outer supporting ring seat, where a center of the outer supporting ring seat is rotatably connected with a middle supporting ring seat through a first supporting shaft rod; a center of the middle supporting ring seat is rotatably connected with an inner supporting ring seat through a second supporting shaft rod; the first supporting shaft rod and the second supporting shaft rod are vertically crossed; a second rotating motor is fixedly installed at one end of the first supporting shaft rod on an outer surface of the outer supporting ring seat; a pow output end of the second rotating motor is fixedly connected with the first supporting shaft rod, an other end of the first supporting shaft rod is provided with a first locking mechanism for position limitation.

The present invention relates to a receiver hitch-mounted ice drill device for ice fishing. The device allows a user to move an ice drill while attached to a vehicle while the drill remains outside of the vehicle. In addition, the device allows a user to remotely operate an ice drill of the device from within a vehicle.

One or more apparatuses are described for drilling, and related methods. The apparatus can include a mast articulation mechanism supported by a base structure, an elongated mast, and a mast positioning actuator comprising a mast actuator that may be supported by a removable mounting element when in a short mast configuration. The method for drilling can include drilling a borehole using the apparatus.

The present invention relates to a hydro auger post hole cleaner. The invention allows for more efficient removal of residual debris from auger-drilled holes. The system can be combined with augers incorporated into engine-mounted machines such as, but not limited to, skid steers, pressure diggers, backhoes and crane diggers. The system uses a toggle-operated pump powered by the machine's battery and controlled with a relay and switch to pump water from water tanks through a water hose to the drill auger on the engine-mounted machine's arm and into an auger-drilled hole. Water causes the debris in the hole to conglomerate and adhere to the auger. The auger is removed from the hole and the adhered conglomeration is removed from the auger, thereby, removing debris from the hole without manual effort.

An articulated support for mast devices of drilling machines, as well as a relative drilling machine, which allows the mast device to rotate by more than 90° from one side to the other with respect to a direction of advancement of the drilling machine is disclosed. The articulated support includes a main body and two rotating bodies, first and second, pivoted to the central body along a same axis and one independently from the other. A linear actuator is pivoted on the main body and is configured to rotate the first rotatable body with respect to the main body around this axis of rotation. Another linear actuator is pivoted on the first rotatable body and is configured to rotate the second rotatable body with respect to the first rotatable body about this axis of rotation. The second rotatable body includes a support to fix a mast device.

A drill device includes a base frame, a feed frame supported for movement relative to the base frame, and a feed device for inserting a drill element into a rock surface. The base frame includes a pair of fluid cylinders. The feed frame extends along a feed axis and includes a plurality of guide bars aligned parallel to the feed axis. The feed device is supported for movement relative to the feed frame in a direction parallel to the feed axis. The feed device includes a first guide member and a second guide member. The first guide member engages a surface of at least one of the guide bars, and the second guide member engages another surface of at least one of the guide bars.

A bollard drilling jig including a base plate, an elongated bar coupled to the base plate, and at least two guide collars spaced apart from each other on the elongated bar. The at least two guide collars each include an interior channel that is sized to receive a drilling tool therethrough.

A drilling apparatus in the form of a Kelly drilling rig including a drilling tool holder for holding a drill rod, in particular a Kelly bar, which can be rotatably driven by a rotary drive via a gearbox, wherein the gearbox includes a gearbox housing with multiple gearbox elements rotatably mounted therein. At least one plastically deformable shock absorber element for absorbing shocks is provided on at least one of the gearbox elements in the gearbox housing.

A rock drilling arrangement, rock drilling rig and drilling method is provided. The rock drilling arrangement includes a drilling boom, which is mountable to a carrier of the rock drilling rig. The boom is provided with two rock drilling units arranged movably in the longitudinal direction of the boom. Further, the drilling units may be moved independently relative to each other.
