The head power is the key component of the ZYWL-6000D horizontal directional drilling machine used in coal mining. By analogy method, the structure of the power head is schemed, and a slope force-amplifier is used in braking, the rubber sleeve chuck in controlled by a pilot-controlled check valve to open and close through a double-channel distributor, in the experiment of the model machine, the maximum torque of the head power is up to 6901N.m, the braking force is up to 4002N.m. In the industrial test, the drilling machine has drilled more than 14000m, and the head power works well. The experimentation and the industrial test show that the head power is qualified to drill with the horizontal directional drilling machine.
