[0023] By setting up a premixing mechanism, raw materials are added into the material box 2 in small batches, and the movement of the material box 2 drives the rotating plate 11 to rotate, so that the rotating plate 11 premixes the raw materials, and then the premixed materials are added into the mixing tank 1 for mixing, thereby improving the mixing efficiency.

[0024] Embodiment 2:

[0025] A reset assembly 3 is provided on the outside of the material box 2. The reset assembly 3 includes a bellows 31.

The outer surfaces of the bellows 31 are fixedly connected to the seat 5 and the outer surface of the material box 2 respectively. The inside of the bellows 31 is connected with an air inlet pipe 32. The air inlet pipe 32 must be provided with a filter (not shown in the figure) for dust prevention. A one-way valve (not shown in the figure) is provided on the body to facilitate one-way circulation of air. A fan 33 is fixedly connected to the inside of the air inlet pipe 32. The fan 33 is electrically connected to the external control circuit. A fixed column 34 is provided at one end of the air inlet pipe 32.

[0027] Embodiment 3: This embodiment is obtained by combining embodiments 1 and 2.

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] During operation, firstly, the raw materials are added into the material box 2 in small batches according to the proportion through the feed pipe 9, and the overall weight of the material box 2 increases, so that it descends along the spiral plate 8. Through the connection between the spiral plate 8 and the rotating column 4, the rotating column 4 drives the rotating plate 11 to rotate inside the material box 2, so that the small batches of raw materials inside the material box 2 can be pre-mixed. At the same time, the bellows 31 is compressed during the descent of the material box 2 to increase the internal air pressure, and the gas pushes the pressure membrane 37, which is dispersed through the incision at the center of the pressure membrane 37, so that the air inside the bellows 31 is discharged to the outside through the air outlet 36, and at the same time drives the pressure column 35 to follow the descent, and in the material box 2 descends to the end, the solenoid valve on the discharge pipe 10 opens, and the premix in the material box 2 falls into the funnel 7 through the discharge pipe 10, and then falls into the mixing tank 1, and then is evenly mixed in the mixing tank 1, and the pressure column 35 contacts the solid column 34, and the internal resistance of the solid column 34 changes under pressure, so that the circuit current changes accordingly, and the control circuit controls the fan 33 to work through the change of current. The fan 33 draws external air through the air inlet pipe 32 and pumps the air into the bellows 31, so that the bellows 31 expands and lifts the material box 2 to rise and reset, thereby preparing small batches of premix continuously.
