[0030] The discharge port can be used to quickly discharge the sand when the sand is mixed. The support rod 12 can increase the contact area between the stirring shaft 11 and the sand. Driven by the motor 13, the stirring shaft 11 can rotate and revolve inside the sand mixing tube 2, and contact the sand at different positions, which can improve the mixing effect of the sand.
