For this, the supporting table 3 comprises a supporting section 31 and a power section 32, a fixed slot 41 is arranged at one end of the driving table 4 facing the stirring bin 1, the outer diameter of the supporting section 31 is larger than the inner diameter of the fixed slot 41, the outer diameter of the power section 32 is smaller than the inner diameter of the fixed slot 41, the power section 32 is positioned in the fixed slot 41, the bottom of the supporting section 31 is rotationally connected with the top of the driving table 4, a plurality of protruding structures 321 are arranged on the outer wall of the power section 32, a first motor 411 is arranged at the bottom of the fixed slot 41, and a first gear 412 is arranged at the power end of the first motor 411 and is in meshed connection with the protruding structures 321. The first motor 411 drives the first gear 412 to rotate, and the first gear 412 is meshed with the protruding structure 321, so that the first gear 412 drives the power section 32 to rotate, and the bottom of the support section 31 abuts against the top of the fixing slot 41, so that the power section 32 drives the support section 31 to rotate. The supporting section 31 will drive the stirring bin 1 at the top and the first auger 2 to rotate in the horizontal direction when rotating, so that the first auger 2 discharges materials in a plurality of directions. To facilitate the movement of the mixer, rollers 40 are mounted at the bottom of the drive table 4.
