Technical Field

The invention mainly relates to a mechanical ejector rod type drill rod which is mainly used for underground coal mines and particularly used for conducting mechanical action on the internal thrust of the drill rod.

Background

The drill rod is a drilling machine accessory commonly used in underground coal mines and can participate in engineering construction of drilling by multiple processes, holes are formed in coal mines in China mostly by adopting a hydraulic punching mode at present, gas extraction efficiency is improved, hydraulic punching is adopted, so that the adopted drill rod is mostly of a high-pressure sealing structure, hydraulic punching is needed to be carried out in the high-pressure sealing drill rod by taking high-pressure water as kinetic energy, a mechanical floating wing deslagging, reaming and hole forming technology is designed according to market demands, the mechanical kinetic energy drill rod capable of directly applying thrust is needed to be provided and used as application implementation, and high-pressure water is not used as kinetic energy when the mechanical kinetic energy drill rod is used.

Disclosure of Invention

The invention mainly provides a mechanical ejector rod type drill rod, wherein a mechanical ejector rod capable of moving and resetting is arranged in the drill rod, a helical blade capable of discharging slag is arranged on the outer surface of the drill rod, male and female connectors capable of being mutually matched and connected are arranged at two ends of the drill rod, the drill rod is connected through a plurality of drill rods, and the mechanical ejector rod can transmit a plurality of thrust forces.

The mechanical ejector rod type drill rod mainly comprises a male connector, a female connector, a drill rod body, a helical blade, a baffle, a mechanical ejector rod and a return spring.

The mechanical ejector rod type drill rod is characterized in that the male joint and the female joint are provided with external threads and internal threads which can be mutually matched and connected, and can also be of a splicing square structure, and the male joint and the female joint are in friction welding with a drill rod body.

The mechanical ejector rod type drill rod is characterized in that a spiral blade is wound on the surface of a rod body, drilling is carried out through the spiral blade to remove slag, and drill blockage caused by excessive slag is prevented.

The mechanical ejector rod type drill rod is internally provided with a mechanical ejector rod, the mechanical ejector rod is of a cylindrical structure, and a positioning step is arranged at the end of the mechanical ejector rod at the female joint end.

The mechanical ejector rod type drill rod is characterized in that the auxiliary centering is carried out at the end of the male connector by depending on an inner hole of the male connector, and the mechanical ejector rod slides at the inner control position of the male connector when the thrust is reached.

The motion of the inside mechanical ejector pin through a mechanical ejector pin formula drilling rod can effectively promote the motion of the floating wing in the sediment reaming cave making technique of the floating wing of a mechanical type, only needs can realize downthehole reaming action through applying mechanical thrust, has effectively avoided carrying out the risk factor that water conservancy reaming caused because of the high pressure, can improve mechanical reaming efficiency, reaches the ore deposit side demand.
