4. The process for producing frost-resistant hydraulic concrete using the frost-resistant hydraulic concrete production apparatus as described in claim 3, characterized in that: S1. Raw material pretreatment: Sampling inspection of cement is carried out to test whether the cement strength meets the standard. Coarse aggregate is screened to remove particles that do not meet the particle size requirements. Fine aggregate is screened to ensure that the fineness modulus of fine aggregate meets the requirements. The moisture content in fine aggregate is tested so that the weight of water content in fine aggregate can be deducted when adding water later. The air-entraining agent is prepared into a solution with a mass fraction of 16%. S2. Ingredients: The raw materials required for concrete production are added to different storage hoppers. By starting the adjusting electric actuator, the adjusting frame is adjusted to adjust the size of the metering trough, thereby adjusting the mix ratio. At this time, the metering motor is started, which drives the metering roller to rotate through the fixed gear and the connecting gear, thus conveying the raw materials in a metered manner. S3. Stir and mix: When the mixing motor starts, it drives the mixing rod through the mixing shaft to mix the materials in the mixing chamber of the mixing tank. At the same time, the start of the mixing motor also drives the driving gear to rotate through the mixing shaft. The rotation of the driving gear, in meshing with the deceleration gear, drives the driven gear to rotate. The rotation of the driven gear, in meshing with the connecting gear ring, drives the rotating disk to rotate. The rotation of the rotating disk drives the premixing gear, premixing frame, and premixing rod to rotate through the fixed bracket. The rotation of the premixing gear, in meshing with the fixed gear ring, rotates on its own axis. The rotation of the premixing gear drives the premixing rod to rotate through the premixing frame, premixing the concrete materials in the premixing chamber. After the concrete in the mixing chamber is mixed, it is discharged from the mixing chamber. At this time, the feeding motor is started. The feeding motor drives the closing plate to rotate through the meshing of the feeding gear and the arc rack. At this time, the closing plate loses its enclosure of the fixed inclined plate, and the materials in the premixing chamber fall into the mixing chamber, which can be directly processed into concrete. S4. Discharge: The concrete inside the mixing chamber is discharged by opening the discharge port at the bottom of the mixing tank.
