Screw propulsion type feeding device

The utility model relates to the technical field of spiral feeding devices, in particular to a spiral propelling type feeding device which comprises a material conveying tank, a propeller is rotatably connected in the material conveying tank, a motor is installed on the top of the material conveying tank, the output end of the motor is connected with the propeller, and an eccentric frame is fixedly arranged at the top end of the outer side of the propeller. The bottom of the side, away from the propeller, of the eccentric frame is rotationally connected with a rotating rod, stirring blades are fixedly arranged on the outer side of the rotating rod, and a fixed gear is fixedly arranged at the top end of the outer side of the rotating rod. When the rotating rod is driven by the eccentric frame to rotate, the materials are stirred by the stirring blades, and the materials are uniformly stirred by the stirring blades under the driving of the eccentric frame, so that the materials are not easy to cake in the mater
