A vehicular auger implement includes an auger having a bit; a walk-behind vehicle having front and rear ends, a forward anchor point, and a rear anchor point; linkage coupling the auger to the walk-behind vehicle; and an actuator for causing the linkage to move between raised and lowered configurations. The linkage includes first, second, and third links. The first link is coupled to the walk-behind vehicle and is rotatable about the forward anchor point. The second link is coupled to and is rotatable about the first link. The second link supports the auger. The third link is coupled to and is rotatable about the second link. The third link is also coupled to the walk-behind vehicle and is rotatable about the rear anchor point.

A golf green hole-making device has longitudinal, radial, and angular directions, and includes a cutting cylinder, a structure, a weight, a weight propulsion device, a soil expulsion piston, a piston driving mechanism, and an expulsion activating mechanism. The cutting cylinder has an open end that is freely movable longitudinally. The structure includes a guide with which the weight engages to move along a weight path between first and second endpoints, when propelled by the weight propulsion device, causing the weight to strike the cutting cylinder and urge the cutting cylinder in the longitudinal direction. The soil expulsion piston moves inside the cutting cylinder along its axis. The piston driving mechanism transfers force from the weight propulsion device to the soil expulsion piston to drive the soil expulsion piston towards the open end. The expulsion activating mechanism engages and disengages the piston driving mechanism in relation to the weight propulsion device.

The present disclosure relates to an extendable apparatus, such as an extendable apparatus for a drill head, a drill head including an extendable apparatus, and a method of operating a drill head. The extendable apparatus includes a base section, a drive section, an extension section, and a functional section. The base section and the drive section are moveable with respect to the extension section and the functional section along a longitudinal axis. The drive section and the functional section are rotationally rigidly coupled to each other. The base section and the extension section are rotationally rigid coupled to each other, and the drive section and the functional section are rotationally moveably coupled to the extension section.

Apparatus for splitting rock, the apparatus comprising: a housing; a drill assembly mounted to the housing and configured to move longitudinally relative to the housing, the drill assembly comprising a shaft having a proximal end and a distal end, a drive element for selectively rotating the shaft and a drill bit mounted to the distal end of the shaft for drilling a hole into rock; a splitter assembly mounted to the housing and configured to move longitudinally relative to the housing, the splitter assembly comprising a tether and a wedge, the tether and the wedge being configured to be moved independently relative to one another; wherein the wedge comprises a proximal end and a distal end, the proximal end of the wedge being wider than the distal end of the wedge; wherein the tether comprises a radially-reduced profile when the wedge is disposed proximal to the tether, and wherein the tether comprises a radially-expanded profile after the wedge is moved distally relative to the tether.

An adjustable drilling rig is provided for drilling and installation of foundational micropile matrices in difficult to access locations. A support frame of separately adjustable legs define a perimeter of the rig and drilling area. A translational frame of arms and a crossbar is selectively mounted to the support frame for easy transport and assembly at remote work sites. The crossbar is selectively slidable along the arms in a Y-axis direction. A crossbar bushing is selectively slidable along the crossbar in an X-axis direction. A mast is slidably attached to and movable with the crossbar. Various adjusters are included and are independently and selectively activated to move the crossbar, and therefore mast and attached drill head, translationally along the X- and Y-axes, optionally Z-axis, and rotationally about the X- and Y-axes to achieve five degrees of freedom in five planes for drilling at any angle within the drilling area.

A system and method for achieving a coring process through construction surfaces is desired. The system can have hydraulic lines, a hydraulic motor, a water connection, a drillshaft, a cylindrical bit, a speed selector, a mast, a gearbox, a spacer, a water pump, a plurality of quick-connect ports, a rotating brace, and a water tank. During operation, the drillshaft will typically be parallel with the mast. The rotating brace enables a huge number of multi-directional drilling (coring) options. The system can cut into concrete, but can also cut metal with the right kind of cylindrical bit, and do so at a variety of angles. The system can also bore into metal, steel, most anything used in residential or commercial construction. The system can core (bore) straight up in the air, straight downward, as well as a variety of angles in-between.

An apparatus, rock drilling rig, method and computer program for executing navigation for a rock drilling rig in a mine tunnel. The rock drilling rig is positioned at faces of rounds and is navigated before initiating drilling. The navigation is executed without a predetermined tunnel line. The realized tunnel line is formed by combining navigation data on several rounds. Length and direction of the round to be drilled next may be adjusted according to need.

A modular assembly for handling excavating equipment is disclosed. The assembly includes a first rotating table having a main body; one or more motors, each having a pinion, associated with the main body; a bearing having a fixed ring constrained to the main body and a movable ring that is coaxial and rotatable with respect to the fixed ring; a dragging sleeve integrally coupled with the movable ring coaxially to the bearing; a ring gear integrally and coaxially coupled with the dragging sleeve to engage with the pinion and be moved in rotation by the motors rotating integrally with the dragging sleeve and integrally with the movable ring. The assembly also has a second rotating table adapted to be coupled to a continuous excavating propeller; a plurality of accessories associated with the first rotating table so it can be coupled to a telescopic Kelly rod or to a continuous excavating propeller or to a casing and excavating pipe.

A mobile auger implement is used with an auger bit and a motor for driving the bit. The implement includes an adjustable base, a central articulating section having a double 4-bar linkage connected to the adjustable base and providing a range of movement, and an auger support and control section connected to the central articulating section and providing an operator handle for guiding the bit. The double 4-bar linkage includes central, base, and distal links and four bars each having a fixed length and being connected to the central link. The first and second bars are parallel to one another at all times, and the third and fourth bars are parallel to one another at all times. The base link is unable to tilt relative to the distal link, such that the auger maintains an angular orientation. Adjustment of the adjustable base affects the angular orientation of the auger.

An apparatus, method and computer program product is provided for determining positional conditions of a satellite positioned mobile mine work machine at a work site. The apparatus determines satellite coverage condition data on a basis of received data of satellite signal availability. Further the apparatus modifies work tasks of the mobile mine work machines of the basis of the determined satellite coverage condition data.
