[0081] S1. Initial rapid mixing: At this stage, the mortar is relatively thin and has good fluidity. The goal is to quickly mix the various components in the mortar. Pour the mortar raw materials into the cylinder 1 according to the proportion. Fully extend the length of the mixing blade assembly 22 of the adjustable mixing mechanism 2 to cover a larger mixing area. Adjust its angle to between 30-45° to increase the mixing range. Keep the telescopic teeth 2212 in a retracted state to keep the blade surface smooth. Then, use the drive device 30 to keep it rotating at a speed of 50-80 RPM to form a large-scale mortar flow and quickly mix the cement, sand, water and other raw materials in the mortar.

[0082] S2, intermediate meticulous mixing, when the mortar fluidity decreases and the viscosity increases, the stirring blade assembly 22 is retracted by half the distance to reduce the stirring area, and the angle is adjusted to 15-30° to reduce the angle to cope with higher resistance, and the telescopic teeth 2212 are extended by half to enhance the shearing and breaking effect of the mortar, and then the driving device 30 is used to rotate at a speed of 30-50 RPM to prevent excessive centrifugal force during stirring to affect the uniformity of the mortar, and the partial shearing effect of the telescopic teeth 2212 fully disperses the beginning of the bonded mortar, and each component is fully integrated;

[0083] S3, late-stage deep mixing, when the mortar appears high viscosity or contains coarse aggregate, the stirring blade assembly 22 is fully retracted to increase the stirring torque, and the angle is adjusted to 0-15° to increase the pushing force on the mortar, and the telescopic teeth 2212 are fully extended to maximize the shear force and enhance the processing of coarse aggregate and viscous mortar, and then the driving device 30 is used to rotate at a speed of 15-30 RPM to avoid equipment overload while the blade can effectively break large particle aggregate under the action of the telescopic teeth 2212 and make the mortar more uniform.

[0084] S4, long-time anti-settling mixing, when the stirred mortar needs to maintain fluidity and prevent settling in the mixing tank, the stirring blade assembly 22 is extended by half to stir without causing excessive disturbance, and the angle is adjusted to 10-20° to ensure light stirring, and the telescopic teeth 2212 are in the retracted state, and then the driving device 30 is used to rotate at a speed of 10-20 RPM to prevent material stratification without excessive stirring damage.

[0085] S5, special material mixing, when the mortar is fiber-reinforced mortar or mortar containing lightweight aggregate and high additive content, the length of the adjustable stirring mechanism 2 is fully extended to ensure sufficient stirring coverage, the angle is adjusted to 15-25° to avoid damage to sensitive materials such as fibers, and the telescopic teeth 2212 are extended by less than half to provide slight shearing action, and then the driving device 30 is used to rotate at a speed of 20-40 RPM to ensure that the material is not damaged during stirring while ensuring uniform distribution;

[0086] S6, automatic cleaning, pour cleaning fluid into the barrel 1, fully extend the length of the adjustable stirring mechanism 2, adjust the blade angle to the maximum, and fully extend the telescopic teeth 2212, then use the driving device 30 to rotate at a speed of 50-70 RPM, the blade rotates automatically to clean the entire device.
