Product Description
Hydraulic Track Mnounted Reverse Circulation Mining RC Drilling Rig for Mining Exploration
Reverse circulation multifunctional drilling rig is a new efficient, environmentally friendly, and multifunctional tracked drilling rig.lt adopts the latest RC drilling and mining technology from abroad, and drilling dust can be effectively collected through dust collectors, avoiding environmental pollution. lt can also be collected and discharged through a cyclone separator, which can be used for sampling and analysis work in geological exploration departments.lt is the preferred equipment for geological exploration drilling and other deep holes.
This drilling rig can use compressed air reverse circulation down-hole drilling on various formations. The lifting of the drilling rig frame, compensation of the drilling frame/multi angle drilling unloading of the drill pipe rotation and feeding,support legs ,hoisting,walking and other movements are all achieved by the hydraulic system, greatly reducing labor intensity, improving construction efficiency and engineering quality.

It is a geological exploration drilling, drilling wells, monitoring wells, ground source heat pump air-conditioning and other deep hole of choice for equipment.
Specification
Applications
Large-scale foundation pile construction: Drilling operations for large-diameter cast-in-place piles in high-rise buildings, residential communities, commercial buildings, factories, etc.
Bridge and high-speed rail pile foundation engineering: Drilling construction of deep-water/large-diameter pile foundations for highway bridges, railway bridges, viaducts, cross-sea bridges, high-speed rail stations, etc.
Port, wharf, and water conservancy projects: Underwater/complex strata drilling for wharf pile foundations, flood control dikes, reservoir dams, cofferdams, river regulation, etc.
Subway, foundation pit, and urban underground engineering: Low-noise construction in urban areas, such as subway retaining piles, foundation pit support piles, and diaphragm wall pilot holes.
Large-diameter deep well and water well drilling: Drilling projects for large-diameter, deep-hole, high-coring-rate wells, including deep water wells, dewatering wells, monitoring wells, and geothermal wells.
Adaptable construction in complex strata: Applicable to various strata such as clay, sand, pebble layers, gravel layers, and weathered rock; fast slag removal, high drilling efficiency, and stable borehole walls.
Key Configurations
Power System: High-power diesel engine/electric motor provides strong power, ensuring efficient reverse circulation drilling.
Hydraulic System: Fully hydraulic control system enables stable operation of the drill frame during lifting, feeding, rotation, winching, and outriggers, ensuring smooth operation.
Reverse Circulation Pump Set: High-flow-rate sand and gravel pump/centrifugal pump creates reverse circulation mud return, rapidly discharging slag and achieving high hole-forming efficiency.
Drill Frame and Mast: High-strength steel structure drill frame provides excellent stability and can meet the requirements of deep hole and large-diameter drilling.
Rotation Mechanism: High-torque rotator drives the drill rod and drill bit to rotate, adapting to complex strata such as clay, sand, gravel, and weathered rock.
Drill Rod and Drill Bit: Thick-walled, high-strength drill rod paired with a special reverse circulation drill bit ensures smooth slag discharge and is wear-resistant and durable.
Winding System: Main and auxiliary winches are used for lifting the drill, lowering the reinforcing cage, and hole cleaning operations.
Support and Traveling Mechanism: Hydraulic outriggers ensure machine stability; optional tracked/vehicle-mounted/walking type for flexible movement and easy relocation.
Control System: Centralized control panel for simple operation; adjustable drilling pressure, speed, and mud flow.
Mud Circulation System: Dedicated reverse circulation piping, faucets, and sealing components ensure continuous reverse circulation drilling.
