Refractory material mixing device

The utility model provides a refractory material mixing device. Relating to the technical field of refractory material processing, the refractory material mixing device comprises a shell, a rotating shaft arranged in the shell and a main stirring paddle connected to the rotating shaft, the rotating shaft is driven by a driving mechanism, a cylinder is arranged in the shell, the surface of the cylinder is connected with an auxiliary stirring paddle, the cylinder and a rotating sleeve are coaxially arranged through a connecting rod, and the rotating sleeve is connected with the rotating shaft through a reverse transmission mechanism; refractory raw materials can flow to the upper part from the bottom, so that the mixing effect and the mixing quality are improved, and the problems that heavier raw materials are deposited to the lower part and lighter raw materials are accumulated to the upper part are avoided; meanwhile, under the action of the reverse transmission mechanism, the rotary sleeve body rotates in th
