The utility model provides an asphalt pump with an electric heating structure, and belongs to the technical field of asphalt pumps. The three-screw pump solves the problems that when an existing three-screw pump serves as an asphalt conveying pump, asphalt can be hardened when the temperature is reduced, and the conveying efficiency is affected. The screw pump comprises a pump body and a screw assembly, a conveying cavity is formed in the pump body, the screw assembly is rotationally arranged in the conveying cavity, an electric heating assembly is further arranged on the pump body and comprises heating rods and a heating ring, and the heating rods are arranged in the conveying cavity and used for heating materials in the conveying cavity; a sealing gland is arranged at the end of the pump body, and the periphery of the sealing gland is sleeved with the heating ring. An oil guide cavity independent relative to the conveying cavity is further formed in the pump body. The asphalt pump has the advantages that th
