When the rotary drilling rig is working, how does the rotated soil enter into the slag bucket?
(1) rotary drilling rig is the soil dust into the drilling bucket by drill pipe and the drill bit rotation and gravity, the soil dust filled with drilling bucket, lifting drill unearthed, so by drilling bucket rotation, soil cut, lifting and unearthed, repeatedly into the hole. According to drilling technology, it is divided into casing drilling method and stable liquid wall drilling method without casing.(3) the rotary drilling rig is mainly composed of operating system, power system, running system and drilling system (guiding column, drill pipe, drilling barrel, long and short spiral rod). Its operating system is mainly controlled by computer and hydraulic transmission. The power system is provided by diesel engine to drill and walk power, and adopts caterpillar type walking system (usually modified by excavator walking system).(4) drilling system is composed of drill bit and drill rod. Drill bit is made up of spiral drill and slag bucket. The drill bit is varied, and different drill bits can be changed according to different geological conditions. The chip type pumping rod drive a rotating drill bit drilling pressure and transfer required torque. The drilling rig is equipped with vertical and horizontal leveling system to ensure the verticality of the bore and to show the depth of the drill tube at any time and to keep abreast of the drilling conditions. The drilling rig has wide application range and high efficiency, and different drill bits can be configured according to different stratum during construction:
Cyclotron is used drilling mud circulation way out of the mud, in the form of power head of rotary drilling, using powerful torque directly to the soil or gravel and other rotary drilling waste slag mining, and then use the spin bucket hole is put forward quickly out of dry soil. Compared with rotary drilling drilling with high efficiency and less pollution and lower cost.
Rotary drilling machine is also called drilling bucket drilling method, short spiral drill bit and other operating device for dry and wet drilling, and the use of rotary digging, successive soil sampling, repeated cycle operation and drilling as the basic function of the drilling machine. The rig can also be equipped with long spiral drilling, casing, and drive device, pedestal drilling bucket and auxiliary device, underground continuous wall grab, precast pile hammer device, rotary drilling rig main parts from site and working device, rotary drilling rig in enter the working state, the control system through the luffing mechanism of mast angle adjustment the mast and leveling, is able to drill vertical drilling, the power head provides torque to the drill pipe and the drill bit to do rotary cutting; and pressurized cylinder to drill pipe and drill through the power head transmission pressure, pressure to achieve drilling bit, when filled with muck, the main hoisting drilling bit left, turning to a certain host open angle drill bottom door, close to Doumen, full of muck, back drilling locations, decentralization of drill pipe, the drill hole drilled into again
