The invention belongs to the technical field of geotechnical
test equipment, and discloses a high-depth draw shaft material
airflow acceleration speed-adjustable angle
impact wear test device which comprises a main body, a simulated rock
mass and a processor, a gas-
solid mixing
pipe is connected with a gas
storage tank through a gas conveying
pipe, and an
electric control valve and an electronic
barometer are arranged at the joint of the gas
storage tank and the gas conveying
pipe; the gas-
solid mixing pipe is connected with the accelerating pipe, the accelerating pipe is connected with a tangential air inlet of the
cyclone separator, a discharging
throat pipe at the bottom end of the
cyclone separator is connected with one end of the straight pipe through the
elbow connecting pipe, the
tail end of the straight pipe is in sliding sealing connection with the
nozzle, and a connecting rod on the
nozzle is connected with the electric cylinder through the rotating rod. Secondary acceleration is carried out through the accelerating pipe and the
cyclone separator, high axial and tangential speeds are provided, the energy
utilization rate is increased, and the
impact speed is controlled through the opening degree of the
electric control valve; the electric cylinder stretches out and draws back, the connecting rod drives the
nozzle to change the angle, then the
impact angle is controlled, and a research equipment foundation is provided for draw shaft design and
effective treatment.
