When the feeding mechanism works, materials fall into the material carrying cavity from the upper part, and when the rotor 2 ' rotates, the stator 3 ' keeps still, the blades 4 ' can move in a reciprocating mode along the radial direction of the rotor 2 ' under the propping action of the inner peripheral wall 1.1a ' of the pump cavity 1.1 ' and the outer peripheral wall 3.1 ' of the stator 2.2 ', so that the outer ends of the blades 2 ' are always in contact with the inner peripheral wall of the pump cavity 1.1 ', the material carrying cavities are isolated from each other, and when a certain material carrying cavity moves to the position of the discharge hole 1.2 ', the materials in the material carrying cavity can be extruded out of the discharge hole 1.2 ' under the extrusion of the corresponding rotor blade 2 '.
