Abstract

The invention relates to a submersible drilling machine which comprises a power source, a mast, a drill pipe, a submersible power head and a drill bit and is characterized by further comprising a sealing rotation connector, a mud transition connector and a winch synchronizing mechanism. The drill pipe is telescopic and is hollow, the submersible power head is connected with an innermost layer rod body of the drill pipe, and the drill bit is connected with a spindle of the submersible power head. Mud is fed from the mud transition connector, and passes through the hollow drill pipe to be sprayed out from the submersible power head or the drill bit. The winch is in linkage with the winch synchronizing mechanism through the submersible power head. The submersible drilling machine is applicable to the drilling process of mud circulation slagging or air circulation slagging. An output shaft of the submersible power head is connected with the drill bit and is fed with the drill bit to operate, the multilayer drill pipe capable of stretching automatically and an electric / hydraulic pipeline on the winch move vertically with the submersible power head, an air or mud delivery channel is arranged in the drill pipe and has certain sealing and pressure keeping effects. The drill pipe has a guide and torsion resisting effect on the drill bit.

Description

technical field [0001] The invention relates to the field of underground construction equipment, in particular to a submersible drilling rig. Background technique [0002] With the development of the building level, the hole-forming operations required by the building are becoming more and more intensive. The traditional hole-forming operations require manual slurry feeding and manual docking of drill pipes, and the traditional drill pipes are driven by the submersible power head at the top of the drill pipe. The drill pipe rotates, so the center of gravity is high and the speed is low, resulting in poor verticality of the hole and a large hole expansion coefficient. Therefore, the existing hole-forming equipment and its construction process are difficult to meet the requirements of the existing construction industry. Contents of the invention [0003] The object of the present invention is to provide an automatic down-the-hole drilling machine, which can overcome the defe...
