The rotation of the transmission gear can drive multiple sets of driven gears that mesh with each other to rotate. A triangular connecting rod is connected to the upper surface of the driven gear. When the transmission gear drives the driven gear to rotate, the driven gear rotates around the outer ring on the inner side of the tooth groove, thereby driving multiple sets of stirring rods connected as a whole on the lower surface to rotate, so that the water-coal slurry is in a flowing state and sedimentation caused by long-term stillness is avoided.
