Vibrating type spiral feeder

The utility model relates to a vibrating type spiral feeder, which is provided with a vibrating and spiral type material conveying device and is applied to conveying and weighting large quantity of powder materials with high precision and high speed. The materials are extruded in rotation manner along a screw rod under the action of a thrusting force and the electromagnetic vibration of the rotating screw rod. In rotating vibrating process, a screw rod shaft is connected to an inner rotor of a magnetic coupler, so the influence of vibration components on connection parts is efficiently reduced, the problem of high demand on weighting precision and speed of wide weighting span is solved, the materials are prevented from being adhered to the screw rod, the vibration and the spiral conveying are organically combined, and the technical demand is met while the conveying efficiency is increased.
