In order to realize the technical purpose, the utility model adopts the following technical scheme:

double helix feeder, including the hopper, the feed inlet, the discharge gate, the bearing, the pivot, helical blade, driven sprocket, the motor, drive sprocket, drive chain, wherein, have the feed inlet on one side of hopper, have the discharge gate at the opposite side lower extreme of hopper, at the outside fixedly connected with bearing of hopper, be connected with the pivot on the bearing, the pivot runs through the hopper, the pivot has two, two pivots are parallel to each other, fixedly connected with helical blade in the pivot, helical blade has one section at least gauge portion, fixedly connected with driven sprocket in the pivot, at the outside fixedly connected with motor of hopper, be connected with drive sprocket on the main shaft of motor, drive chain connects around on driven sprocket and drive sprocket.

Preferably, the diameter-changing portion is located below the feed port.

Preferably, the two rotating shafts are driven by two motors respectively.

In the above technical scheme, the hopper is used for containing materials; the feed inlet is used for adding materials into the hopper; the discharge port is used for outputting materials; the bearing is used for bearing the rotating shaft; the bearing is used for bearing the helical blade; the helical blade plays a role in pushing materials in the hopper under the rotary motion; because the double helical blades are driven to rotate side by the double rotating shafts, materials are extruded by the double helical blades in the pushing process, and a certain crushing effect is achieved; the diameter-changing part on the double-helix blade is beneficial to overcoming the problem of material blockage; the driven chain wheel on the rotating shaft and the driving chain wheel on the motor are driven by the transmission chain, so that the rotating shaft is driven by the motor.

The utility model is especially suitable for feeding powder; the materials can be loess, clay, fly ash, gangue powder, etc.
