The invention discloses an auxiliary material adding device for asphalt production and processing. The auxiliary material adding device comprises processing equipment, a feeding box, a fixing plate, a lifting plate and a lead screw, the lifting plate is slidably connected to one side of the feeding box, the feeding box is fixedly connected to the upper surface of the lifting plate, guide plates are fixedly connected to the two sides of the interior of the feeding box correspondingly, and connecting rods are rotationally connected to the two sides of the bottom end of the interior of the feeding box correspondingly. Through an arranged rotating disc, the rotating disc can be driven to rotate through a driving motor, and a vibration contact on the surface of the rotating disc can rotate, through rotation of the vibration contact, the vibration contact can collide with one end of a vibration plate, so that the position of the vibration plate can be moved, through arranged reset springs, when the vibration contact is separated from the vibration plate, the vibration plate can be pulled back to the initial position through the elastic force between the reset springs, and a vibration rod on the upper surface of the vibration plate can be controlled to drive a control valve to move in the mode, so that the discharge amount of auxiliary materials in the feeding box can be controlled, and convenience is achieved.
