The invention discloses a soil oiler for sludge incineration. The soil oiler comprises a hollow shell, multiple supporting legs fixed to the bottom of the hollow shell through connecting plates and integrated base plates arranged at the bottoms of the supporting legs. A supporting plate integrated with the supporting legs is arranged between the multiple supporting legs. An electromotor fixing ring is fixed to the upper surface of the supporting plate through a bolt. An electromotor is connected in the electromotor fixing ring in a sleeved manner. A spiral conic column is welded to the end of a spindle of the electromotor. A conic hollow structure is arranged in the center of the bottom of the hollow shell. The spiral conic column is located at the center of the conic hollow structure. According to the soil oiler for sludge incineration, dried sludge can be effectively coated with oil, and therefore the sludge has the characteristic of combustion; and in addition, by means of the soil oiler, diesel oil and soil can be fully mixed, and therefore the utilization rate of the diesel oil is increased.
