A ratcheting auger bracing device having a support frame with spaced-apart elongated side bars and first and second end bars connecting the side bars, and a pair of pivotable braces each having a proximal hinge end secured pivotally to and around the end bars of the support frame, a distal end bar, and a pair of opposed arms connecting the distal end bar to the proximal hinge end. The opposed arms are angled downwardly, acing the shaft of the auger section, to provide improved operation of the ratcheting auger bracing device in muddy operation conditions. An elevating frame provides an elevating base and legs that elevate the support frame and the hinged pair of pivotable braces at a distance above the ground level, and positions the hinged ends of the pivotable braces a distance above the ground level that avoids or prevents mud that may pool around the well hole.

The disclosure provides an earth auger comprising a supporting assembly, a drill pipe assembly including a drill pipe, a driving assembly arranged on the supporting assembly to drive the drill pipe assembly to work and a brake assembly including a trigger component that brakes the driving assembly and a brake lever connected through a first pivot and matched with the trigger component. The projection part of the brake lever on the plane perpendicular to the axis of the drill pipe is located outside the projection of the supporting assembly on the plane perpendicular to the axis of the drill pipe. The earth auger provided by the disclosure can effectively prevent accidents and improve the safety performance of the earth auger.

A remote-controlled adjustable-speed screw drill for gas-drive hydraulic-motive during gas drilling is provided, including a piston speed control system, a motor assembly, a cardan shaft assembly and a transmission shaft assembly which are connected with each other from up to down in sequence. The motor assembly includes air inlets, a cam, air cylinders, pistons, a connecting rod, air outlets, liquid inlets, hydraulic cylinders, liquid check valves, a liquid storage chamber, liquid outlets, a liquid injecting chamber, a liquid injecting hole, an anti-drop cap, a rotor, a stator, and a motor assembly housing. The present invention utilizes the high-pressure gas injected by the gas drilling to drive the pistons to move back and forth at high-speed, so as to drive the incompressible liquid within the driving screw to achieve the self-circulating motion, and the screw rotor is driven to rotate by the liquid.

A post hole digger couples to the power take-off (PTO) shaft of a tractor and uses rotation from the PTO shaft to rotate an auger. A top support arm rotatably coupled to the top pin of the tractor's three point hitch supports the gearbox that translates rotation to the auger. A support frame extends upwardly from the right and left lift arms of the three point hitch and inwardly to support the top support arm from beneath. The support frame is shaped generally as an inverted “U,” with space created between the right and left lift arms to prevent interference with the rotating shaft that translates rotation from the PTO shaft to the gearbox. A shield coupled to the gearbox covers the moving parts of the joint between the rotating shaft and the gearbox and protects users during use of the auger.

A hole opener configured for use with a power unit to open a hole. The hole opener comprises a gearbox including a hydraulic inlet fluidly coupled to the power unit and an exciter fluidly coupled to the hydraulic inlet, the exciter being coupled to a gear train including an imbalanced mass which is configured to generate vibrations upon receipt of pressurized hydraulic fluid from the hydraulic inlet. The hole opener further comprises a connector coupled to the gearbox for receiving the vibrations, the connector defining a void, and a hammer slidably coupled to the connector within the void, the hammer configured to receive the vibrations from the connector and to transmit the vibrations to the hole.

A cutting head includes a main body that is attachable to an ice drill shaft at a top side. The main body includes a bottom side that has a bottom peripheral surface. The cutting head includes at least one cutting edge that is disposed on the main body. The cutting edge is configured to perform a cutting operation at the bottom side of the main body. The cutting head includes a cutting rate control pad that is disposed on the bottom side of the main body. The cutting rate control pad extends away from the bottom peripheral surface.
