Abstract

The invention discloses a screw drilling tool which is easy to assemble and disassemble. The drill bit is connected to the rotating shaft through transmission, and the rotating shaft is assembled and installed with the drill bit through the tool holder; the drill bit and the tool holder of the screw drilling tool are easy to disassemble, and the drill bit can be assembled in place by setting the base plate and the induction block; The spiral cooling pipe and the liquid storage chamber utilize the cooperation of the eccentric wheel and the return spring to make the heat exchange medium in the spiral cooling pipe and the liquid storage chamber circulate and flow, and through the operation of the refrigeration plate, the heat exchange medium is evenly distributed to the screw drilling tool. Effective cooling; by setting the adjusting screw to control the included angle of the first connecting rod, it is convenient to adjust the working radius of the drill bit, and the first connecting rod and the second connecting rod are installed through the rotation of bolts and nuts, which is convenient for the disassembly and maintenance of the drill bit.

Description

Technical field[0001]The present invention relates to the field of oilfield mining, and is specifically a screw drill for disassembly.Background technique[0002]The screw drill is a pilot driving force drill with a drilling liquid to convert the liquid pressure into mechanical energy. When the mud pump pump flows through the bypass valve into the motor, in the motor, the outlet forms a certain pressure difference, push the rotor to rotate the axis of the rotor, and transmit the rotational speed and torque through the universal shaft and the drive shaft to the drill bit. Thereby achieving drilling work. The existing screw drill is in use, the drill is not convenient for disassembly and maintenance and adjustment, and the screw drill cannot obtain uniform and timely cooling, affecting the normal operation of the screw drill; therefore, it is necessary to improve the prior art.Inventive content[0003]It is an object of the present invention to provide a screw drill that is easy to disass...
