Leakage-proof spiral feeder

The utility model discloses an anti-leakage spiral feeder which comprises a whole device, a supporting mechanism used for supporting the whole device is arranged at the bottom of the whole device, a feeding mechanism used for feeding is arranged at the top of the supporting mechanism, and a lifting mechanism used for lifting materials is arranged in the supporting mechanism. The rotary motor is arranged on one side of the bottom of the leakage-proof pipe, so that moisture in materials cannot directly drop above the rotary motor, the moisture can be prevented from influencing use of the rotary motor, normal transportation of the materials can be guaranteed through the lifting mechanism, the service life of the equipment is prolonged, and the production cost is reduced. Through cooperative use of the inclined plate, the magnetic block, the drying box and the water outlet pipe, moisture entering the protective shell can be treated, the moisture can be discharged out of the protective shell through the inclined p
