The invention discloses an agitating tank of bituminous mixture cold regeneration and agitation equipment, which comprises a tank body and an inlet and an outlet formed on the tank body, wherein two rotatable agitating shafts are arranged inside the tank body; at least three agitating blade devices are arranged on each agitating shaft; each agitating blade device comprises an agitating blade and a holder; the inlet is formed above one end in the axial direction of the agitating shaft of the tank body; the outlet is formed below the other end in the axial direction of the agitating shaft of the tank body; and the plane of the agitating blade and the axial line of the agitating shaft form an included angle Alpha. Compared with the prior art, the inlet and the outlet of the tank body are formed on the two ends in the axial direction of the agitating shaft of the tank body; the agitating blades and the axial direction of the agitating shaft incline to form the included angle; materials tobe agitated enter the inlet, are output from one end of the agitating shaft to the other end thereof in a mixed way under the agitating action of the inclined agitating blades, and meanwhile, during the agitating process, the agitating tank can realize continuous feeding after the materials to be agitated are mixed.
