Asphalt mixture heating and heat preservation equipment

The invention discloses asphalt mixture heating and heat preservation equipment, and relates to the technical field of asphalt mixing equipment. The device comprises a frame body, and a heating and heat preservation box body is clamped to the inner side of the frame body; the driving rod is arranged on one side in the heating and heat preservation box in a penetrating mode, a reduction gearbox is fixed to one side of the driving rod, and a driving motor is arranged on the side, away from the driving rod, of the reduction gearbox; the heating mechanism is arranged at the upper end of the first upper cabin door. According to the invention, the residual asphalt mixture after construction can be introduced into the heating and heat-preserving box body from the feeding hole in the top of the heating and heat-preserving box body, then the heating mechanism is ignited by the automatic ignition device, and then the asphalt mixture is gradually heated by heat radiation generated by the heating assembly I and the heati
