[0027] In this embodiment, a driving motor 120 is fixedly installed on one side of the mixing chamber 100, and the driving motor 120 is used to drive the screw shaft 110 to rotate to mix the materials.

[0028] In this embodiment, there are two crushing paddles 221 , which are symmetrically arranged about the center line of the sand material delivery assembly 200 , and one end of the two crushing paddles 221 is provided with mutually meshing synchronous teeth.

[0029] Specifically, the two oppositely arranged rotatable crushing paddles 221 are rotated during the feeding process to crush and disperse the aggregated quartz sand.

[0030] In this embodiment, the end of the screw shaft 230 and the end of the rotating wheel 330 are both driven by a stepper motor, and the input end of the stepper motor is electrically connected to a control module for speed distribution of the two motors.

[0031] Specifically, quartz sand and various additives are added in proportion under different speed ratios of the spiral shaft 230 and the wheel 330, thereby realizing automatic proportioning and feeding.
