In this embodiment, four groups of turning mechanisms 310 are arranged, and the turning mechanism 310 comprises a movable arm 311 arranged radially along the material barrel 1, and a turning plate 312 fixedly connected to one end of the movable arm 311 and arranged horizontally, and the other end of the movable arm 311 is rotatably connected to the bottom of the material barrel 1, and the turning plate 312 can be driven by the driving mechanism 320 to reciprocate in a vertical plane;

[0019] The movement of the flipping plate 312 mainly includes two processes. One is that the flipping plate 312 rotates upward to drive the material below to move upward so that the material at the bottom can be affected by the stirring mechanism 2. The other is that the flipping plate 312 rotates downward to drive the material above to move downward and mix evenly with the material below, which is conducive to the full mixing of the material in the barrel 1.

[0020] In order to realize the synchronous movement of the four groups of turning mechanisms 310, in a further embodiment, the driving mechanism 320 includes a transmission assembly connected to the movable arms 311 and a power assembly connected to each group of the transmission assemblies, and the power assembly drives the multiple movable arms 311 to move synchronously through the transmission assembly;

The vertical rod 322 penetrates the bottom of the barrel 1 and is connected to the power assembly and driven by the power assembly to perform vertical reciprocating motion.

[0022] When the vertical rod 322 reciprocates vertically, the movable arm 311 is driven to reciprocate through the transmission rod 321;
