The beneficial effects of the utility model include:

1) a plurality of groups of flow breaking rods are arranged in the middle of the stirring blade, and when materials flow inwards along the flow guide frame, the agglomerated or caked materials can collide with the flow breaking rods and be broken; in the continuous stirring process, the materials continuously pass through the flow breaking rod, the flow breaking rod generates turbulent flow to enable the flow velocity of material clusters to be uneven, the material clusters and the turbulent flow are mutually rubbed, squeezed and fused, and when the friction force is greater than the agglomeration cohesion force, the material clusters or agglomerates can be crushed and fused again, so that the aim of uniform stirring is fulfilled; the caking and the pilling in the stirring process are reduced, and the processing quality of the material is ensured.

2) The friction force existing among the materials changes the acting force direction among the materials after passing through the inclined plane flow deflector, so that the materials flow better along the guide frame, and the materials and the flow breaking rod effectively collide and rub with each other, thereby achieving the purpose of more uniform material mixing.

3) Stirring vane sets up the inclined plane water conservancy diversion frame, and this inclined plane is outer to be wide adduction, and when the mixer started, the material was along the inward flow of water conservancy diversion frame, and especially the difficult material that stirs in top can constantly sink because the water conservancy diversion frame exists to can not form the below stirring, and the top material fuses the uneven condition.
