The invention discloses a sludge drying machine, and belongs to the technical field of sludge treatment. The sludge drying machine comprises a base, a drying box, a hollow shaft, a driving motor and a heating box, first fixing shafts are arranged at the two ends of the hollow shaft, second fixing shafts are connected to the ends of the first fixing shafts, and oil passing coil pipes are arranged on the periphery of the hollow shaft; the two ends of the oil passing coil pipe are located in the hollow shaft and penetrate through the first fixing shaft and the second fixing shaft, the oil outlet end of the heating box is connected with an oil conveying pipe, and an infusion pump is arranged at the position, close to the heating box, of the oil conveying pipe. Heating oil is used as a heat source, the problems that high-temperature steam is used as a heat source to enter a pipeline to dry sludge, the pipeline for conveying the heat source is prone to corrosion and burst, and the possibility of potential safety ha
