The utility model discloses a spiral agitating device for asphalt concrete transfer car which comprises one or more agitating shafts and several agitating units which are connected with the agitating shafts by fasteners while the agitating unit comprises an agitating lever and an agitating vane which is connected with the agitating lever and the agitating vane is in the shape of a flabelliform ring. The spiral agitating device of the utility model can balance the motion of agitation of the variable-pitch spiral and the double horizontal shaft paddle, so as to maintain a good effect in the axial flow and the radial motion. Moreover, the adoption of the band type flabelliform ring vane with big angle provides a smooth radial agitation and an obvious axial thrust. The mixture blends smoothly in the axial flow without the extreme situations such as short agitation or over agitation and can effectively eliminate the secondary isolation in the mixture.
