The invention discloses a rotating well boring machine, relates to the technical field of well boring equipment, and aims to solve technical problems that by using a conventional well boring machine, holes are collapsed or tilted and a corn head is clamped in the well boring process. The rotating well boring machine comprises a shell as well as a lifting device and a well boring device, wherein the lifting device comprises an end cover, a balancing weight, a balance weight guide rod, a lifting rod, a spring clamping piece, a lifting baffle plate, a guide rod and a lifting rope; the end cover is arranged at the top of the shell; the well boring device comprises a motor, a water tank, a rotating shaft, a drill bit and a spiral blade; the water tank is arranged inside the shell; the motor is arranged inside the inner cavity of the water tank; the upper end of the rotating shaft is connected with a motor shaft; the lower end of the rotating shaft penetrates through the bottom surface of the water tank and is connected with the drill bit; the spiral blade is arranged on the rotating shaft. By adopting the rotating well boring machine, phenomena of hole collapse and tilting and corn head clamping can be effectively prevented, and the rotating well boring machine has the advantages of stable structure, convenience in operation and high working efficiency.
Description
technical field [0001] The invention belongs to the technical field of drilling equipment, in particular to a rotary drilling machine. Background technique [0002] Drilling rigs are mainly used to develop groundwater resources, including domestic water, agricultural water and industrial water drilling, and are also suitable for hydrogeological exploration, construction engineering, bridge foundation drilling, etc. The working method of the well drilling machine is the pump suction reverse circulation type. Its working principle is: under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank to the bottom of the well through the return ditch along the annular gap of the well hole. At this time, the turntable drives The drill pipe drives the drill bit to rotate for drilling, and the negative pressure established by the mud pump sucks the debris mud into the inner cavity of the drill pipe, then rises to the faucet, and is discharged into t...
