The invention discloses a powerless mixing spray gun for
refractory materials. The powerless mixing spray gun for the
refractory materials comprises a
spray nozzle and a spray gun, wherein the outer wall of the lower part of the
spray nozzle is in threaded installation with the connection part of the spray gun through external threads; a mixing component is mounted at the center of the interior ofthe
spray nozzle; the lower part of the outer wall of a vertical rod is fixedly connected with a round rod through a cross rod, and the upper part of the round rod is rotationally connected with a water inlet
pipe through a sealing bearing. A powerless repairing spray gun for the
refractory materials is scientific and reasonable in structure, and safe and convenient to use; and a mixing assemblyis provided; a water inlet
pipe, a circular rod, blades, a vertical rod, a cross rod, a supporting rod, a second sleeve ring, a spray head and the
nozzle are matched; water can be injected by an outerhigh-pressure water pump utilizing the water inlet
pipe, so that the water at the spray head can be sprayed out; and meanwhile, water can be used for driving the blades to rotate the spray head, anda
water net is formed at the second sleeve ring, and thus full mixing is realized; and the problem that a motor is used in the prior art to realize rotating mixing to cause excessively high requirement and inconvenient carrying can be avoided.
