The fixed upper portion that sets up at base 1 of shell 2, first mixing arrangement 4 and second mixing arrangement 5 all set up the inside at shell 2, feed arrangement 6 sets up on first mixing arrangement 4, can pour into raw and other materials into first mixing arrangement 4 through feed arrangement 6 and carry out preliminary mixing, be provided with coupling assembling 7 between first mixing arrangement 4 and second mixing arrangement 5, coupling assembling 7 is after first mixing arrangement 4 accomplishes the preliminary mixing of raw materials, arrange the concrete admixture after accomplishing preliminary mixing in first mixing arrangement 4 into second mixing arrangement 5 and carry out the secondary and mix. The raw materials added into the concrete admixture are more in variety, and the raw materials of the concrete admixture are classified and mixed by the arrangement of the first mixing devices 4, so that the mixing efficiency is improved, and the phenomenon that the raw materials precipitate after standing for a long time can be avoided. The operation principle of the temperature control device 3 is as follows, for convenience of understanding, only one of the first mixing devices 4 is taken as an example here, after the feeding device 6 injects the raw material into the first mixing device 4, the flow meter arranged on the feeding device 6 detects the amount of the raw material entering the first mixing device 4, and after the specified amount is reached, the flow meter sends a signal to the feeding device 6, and the feeding device 6 stops feeding. Then first mixing arrangement 4 just can begin to start, and first mixing arrangement 4 mixes the stirring to its inside concrete admixture raw materials, when stirring, the phenomenon that the concrete admixture that is located first mixing arrangement 4 can appear cooling or heat up, and the temperature sensor 3g that sets up in first mixing arrangement 4 this moment can detect the temperature in first mixing arrangement 4. It is noted that before use, the operator needs to input a value to the processor according to the actual optimum temperature for stirring, and the input value is referred to herein as a preset value. Thus, when the temperature sensor detects a temperature change, the processor can determine the temperature sensor 3 g. If the processor determines that the value detected by the temperature sensor 3g has exceeded a predetermined value, i.e. the temperature in the first mixing device 4 is high, then the first mixing device 4 needs to be cooled down. At this time, the first on-off valve 3e is opened, and since the water pumps are disposed in the cold water tank 3a and the hot water tank 3b, and then the water pump in the cold water tank 3a injects the cold water in the cold water tank 3a into the hot water tank 3b through the first on-off valve 3e and the first circulation pipe 3c, since the first circulation pipe 3c is disposed around the first mixing device 4, the cold water flows through the first circulation pipe 3c after being discharged from the cold water tank 3a, and at this time, the cold water in the first circulation pipe 3c absorbs the heat of the first mixing device 4, thereby achieving the effect of cooling the first mixing device 4, and since the temperature sensor 3g is electrically connected to the first mixing device 4, the first mixing device 4 is also affected by the temperature sensor 3g, and the stirring speed of the first mixing device 4 is gradually slowed down, thereby further slowing down the mixing process of the concrete admixture raw materials. When the temperature of the first mixing device 4 is too low, the temperature sensor 3g sends a signal to the second on-off valve 3f, the second on-off valve 3f is opened, and then the water pump provided in the hot water tank 3b is started, and the water pump in the hot water tank 3b delivers the hot water to the cold water tank 3a through the second circulation pipe 3 d. And the hot water in the hot water tank 3b is the cold water which has just absorbed heat from the first mixing means 4 through the first circulation pipe 3 c. This ensures that the concrete admixture in the first mixing device 4 can be stirred in a suitable temperature environment. A discharging device is arranged below the second mixing device 5, and when the second mixing device 5 finishes mixing the concrete admixture, the concrete admixture is discharged. Therefore, the output quality of the concrete admixture can be ensured while energy is saved.

Feed arrangement 6 sets up on the lateral wall of first hybrid shell 4f, after feed arrangement 6 added the raw materials in first hybrid shell 4f, the raw materials injection volume of feed arrangement 6 can be monitored to the flowmeter on feed arrangement 6 this moment, after reaching appointed quantity, the flowmeter can give first drive arrangement 4a with signal transmission this moment, first drive arrangement 4a just can start afterwards, first drive arrangement 4a can drive transmission assembly 4b operation, and then will make transmission assembly 4b drive (mixing) shaft 4c rotatory, because first flight 4d is fixed the setting on (mixing) shaft 4c, so after (mixing) shaft 4c was driven rotatory, first flight 4d just can be driven rotatory by (mixing) shaft 4c this moment. After first flight 4d is rotatory, first flight 4d can drive the raw materials of the concrete admixture of first mixed shell 4f bottom this moment and rise, because seted up recess 4e on first flight 4d again, will make like this and spill over from recess 4e by the partial concrete admixture that first flight 4d drove, thereby reach the purpose that the concrete admixture raw materials rolled from top to bottom in first mixed shell 4f, so just realized that first mixing arrangement 4 can be more even carry out the technical requirement of stirring to the concrete admixture.

After the first rotary driver 4a1 is started, the first rotary driver 4a1 drives the first gear 4a2 to rotate, and further drives the second gear 4a3 engaged with the first gear 4a2 to rotate, because the second gear 4a3 is fixedly connected with the rotary disc 4b1, after the second gear 4a3 rotates, the rotary disc 4b1 also rotates, the rotary disc 4b1 drives the toothed ring 4b3 to rotate through the connecting rod 4b2, and because the toothed ring 4b3 is engaged with the third gear 4b4, when the toothed ring 4b3 rotates, the third gear 4b4 is driven to rotate. This causes the stirring shaft 4c disposed at the lower portion of the third gear 4b4 to be rotated, thus achieving the transmission function of the transmission assembly 4 b.

As shown in fig. 10-13:
