[0015] Furthermore, the production process of the frost-resistant hydraulic concrete comprises the following specific steps:

[0016] 1. Raw material pretreatment:

[0017] Sampling and testing cement to test whether the strength of cement meets the standard, screening coarse aggregate to remove particles that do not meet the particle size requirements, and cleaning the soil, stone powder, etc. attached to the surface of coarse aggregate, screening fine aggregate to ensure that the fineness modulus of fine aggregate meets the requirements, and testing the water content in fine aggregate so that the weight of water in fine aggregate can be deducted when adding water source later, and the air entraining agent is configured into a solution with a mass fraction of 16%;

[0018] 2. Ingredients:

[0019] The raw materials required for concrete production are added into different storage hoppers. By starting the adjusting electric push rod, the adjusting electric push rod adjusts the adjusting frame and adjusts the size of the quantitative slot to achieve the effect of adjusting the ratio. At this time, the quantitative motor is started, and the quantitative motor drives the quantitative roller to rotate through the fixed gear and the connecting gear to transport the raw materials quantitatively.

[0020] 3. Stir and mix:

[0021] When the mixing motor is started, the mixing rod will be driven by the mixing shaft to mix the materials in the mixing chamber of the mixing tank. The starting of the mixing motor will also drive the driving gear to rotate through the mixing shaft. The rotation of the driving gear will drive the driven gear to rotate under the meshing with the speed reduction gear. The rotation of the driven gear will drive the rotating disk to rotate under the meshing with the connecting gear ring. The rotation of the rotating disk will drive the premixing gear, the premixing rack and the premixing rod to rotate through the fixed bracket. The rotation of the premixing gear will rotate by itself under the meshing with the fixed gear ring. The self-rotation of the premixing gear will drive the premixing rod to rotate through the premixing rack to premix the concrete materials in the premixing chamber. When the concrete in the mixing chamber is mixed, the concrete in the mixing chamber is discharged. At this time, the feeding motor is started, and 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 closure to the fixed inclined plate, and the material in the premixing chamber will fall into the mixing chamber, so that the concrete production and processing can be carried out directly.

[0022] 4. Discharging:

[0023] The concrete in the mixing chamber is discharged by opening the discharge port at the bottom of the mixing tank.

[0024] Beneficial Effects

[0025] The present invention realizes quantitative addition of antifreeze type hydraulic concrete through the setting of the quantitative mechanism, starts the adjustment electric push rod, and drives the adjustment frame to slide with the help of the connecting rod. This sliding process can flexibly adjust the volume of the quantitative groove. Through the fine adjustment of the quantitative grooves on the two quantitative rollers, the diversified setting of the proportions of various concrete production materials can be easily achieved. After the adjustment is completed, the quantitative motor is started, and under the coordinated meshing action of the fixed gear and the connecting gear, the quantitative roller starts to rotate at a uniform speed, thereby smoothly conveying the concrete production materials in the storage hopper to the mixing tank through the feed pipe. The whole process does not require manual intervention for tedious measurement and weighing operations, which reduces labor intensity and significantly improves work efficiency.

[0026] In addition, through the setting of the premixing mechanism, the pre-proportioning and mixing of antifreeze type hydraulic concrete is realized. When the mixing motor is started, its power is transmitted through the mixing shaft, driving the mixing rod to efficiently mix the materials in the mixing chamber in the mixing tank. At the same time, the operation of the mixing motor will also drive the mixing shaft to drive the driving gear to rotate synchronously. The meshing action of the driving gear and the speed reduction gear further drives the driven gear to rotate, and the meshing of the driven gear and the connecting gear ring causes the rotating disk to rotate. The rotating disk drives the premixing gear, the premixing rack and the premixing rod to rotate in coordination with the help of the fixed bracket. The premixing gear is in meshing with the fixed gear ring. The premixing gear will rotate during the process, and the rotation of the premixing rod will drive the rotation of the premixing rod, thereby pre-mixing the concrete materials in the premixing chamber. When the concrete mixing operation in the mixing chamber is successfully completed and discharged smoothly, the feeding motor is started. The feeding motor drives the closing plate to rotate in an orderly manner through the engagement of the feeding gear and the arc-shaped rack, so that the closing state of the closing plate on the fixed inclined plate is released. At this time, the premixed materials in the premixing chamber will naturally fall into the mixing chamber, and then they can seamlessly enter the next stage of concrete production and processing. In this way, the production interval is effectively shortened and the production efficiency is greatly improved.

[0027] In addition, through the setting of the replacement mechanism, the mixing rod can be quickly replaced. When the mixing rod is severely worn due to long-term use, it is only necessary to pull the sliding rod downward, and the sliding rod will drive the limit block to slide downward until the limit block is out of the limit groove. At this time, the mixing rod can be easily removed for quick replacement. The operation process is simple and easy, which further improves work efficiency.

[0028] In addition, through the setting of the above-mentioned mechanism, the present invention not only successfully realizes the precise quantitative addition, pre-proportioning and mixing of frost-resistant hydraulic concrete production materials, effectively reduces labor intensity, significantly improves work efficiency, and shortens production intervals, but also realizes the rapid replacement of mixing rods, effectively improving the production efficiency of frost-resistant hydraulic concrete and the convenience of equipment maintenance.

10. The production process of a frost-resistant hydraulic concrete according to claim 1, characterized in that:

1. Raw material pretreatment: Sampling and testing cement to test whether the strength of cement meets the standard, screening coarse aggregate to remove particles that do not meet the particle size requirements, and cleaning the soil, stone powder, etc. attached to the surface of coarse aggregate, screening fine aggregate to ensure that the fineness modulus of fine aggregate meets the requirements, and testing the water content in fine aggregate so that the weight of water in fine aggregate can be deducted when adding water source later, and the air entraining agent is configured into a solution with a mass fraction of 16%; 2. Ingredients: The raw materials required for concrete production are added into different storage hoppers. By starting the adjusting electric push rod, the adjusting electric push rod adjusts the adjusting frame and adjusts the size of the quantitative slot to achieve the effect of adjusting the ratio. At this time, the quantitative motor is started, and the quantitative motor drives the quantitative roller to rotate through the fixed gear and the connecting gear to transport the raw materials quantitatively.

3. Stir and mix: When the mixing motor is started, the mixing rod will be driven by the mixing shaft to mix the materials in the mixing chamber of the mixing tank. The starting of the mixing motor will also drive the driving gear to rotate through the mixing shaft. The rotation of the driving gear will drive the driven gear to rotate under the meshing with the speed reduction gear. The rotation of the driven gear will drive the rotating disk to rotate under the meshing with the connecting gear ring. The rotation of the rotating disk will drive the premixing gear, the premixing rack and the premixing rod to rotate through the fixed bracket. The rotation of the premixing gear will rotate by itself under the meshing with the fixed gear ring. The self-rotation of the premixing gear will drive the premixing rod to rotate through the premixing rack to premix the concrete materials in the premixing chamber. When the concrete in the mixing chamber is mixed, the concrete in the mixing chamber is discharged. At this time, the feeding motor is started, and 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 closure to the fixed inclined plate, and the material in the premixing chamber will fall into the mixing chamber, so that the concrete production and processing can be carried out directly.

4. Discharging: The concrete in the mixing chamber is discharged by opening the discharge port at the bottom of the mixing tank.
