Star-shaped feeding device for preventing blockage

The utility model discloses a star-shaped feeding device for preventing blockage. The device comprises a shell, a rotor and blades, wherein a feeding hole is formed on the upper part of the shell; a discharge hole is formed on the lower part of the shell; the blades are uniformly distributed on the rotor; a conveying storage silo is formed between two adjacent blades; and an offset distance S is formed between a center line of the feeding hole and an axis of the rotor. The utility model has the advantages that: the center line of the feeding hole deviates from the axis of the rotor, and the torque of a motor for driving the rotor to rotate is reduced by utilizing self gravity of materials to be conveyed; and therefore, the star-shaped feeding device is difficultly blocked, and a star-shaped feeder smoothly and uniformly feeds materials.
