Abstract

The invention discloses a directional water feeder and a directional drilling machine, wherein the directional water feeder comprises a shaft, a bearing, an outer pipe and a central cable-traverse device; the shaft is connected with the outer pipe through the bearing; and the central cable-traverse device is arranged on the outer pipe. Thus, the directional water feeder disclosed by the invention can solve the problems of inconvenient measurement signal and unreliable measurement and obviously increase the drilling efficiency of a drill hole of the directional drilling machine.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a directional water feeder and a directional drilling machine. Background technique [0002] Underground coal mines, in tunnel directional drilling and geologically controlled directional drilling, measurement-while-drilling systems are required to monitor drilling trajectories and correct deviations in time. At the same time, the water feeder is required to deliver high-pressure flushing medium to the inside of the drill pipe to drive the power motor at the bottom of the hole. Therefore, the water feeder will affect the reliability of the measurement and the efficiency of drilling. [0003] At present, there are mainly two types of water feeders: [0004] 1) A water feeder that can only provide flushing medium to the inside of the drill pipe, but cannot transmit the measurement signal at the bottom of the hole. When drilling to measure and extract data, the water feeder ne...
