Abstract: The present invention is a mechanical technology that kills parasitic pests, harmful bacteria and weed seeds in the soil by using high-temperature steam while moving forward by using a caterpillar with a self-powered device in order to smoothly perform the eco-friendly high-temperature steam soil disinfection in all types of soils, such as clays and sandy soils, having suitable moisture content; a mechanical technology in which the steam boiler is operated with power of an A/C generator to produce steam the steam is supplied to the re-heater installed on an upper portion of a nozzle through a high-pressure steam hose to increase the steam temperature to reheat the steam with high-temperature dry steam, thereby increasing the efficiency and effectiveness of high-temperature steam soil disinfection, and a saw blade type crusher is activated with the pre-generated electrical energy to crush and soften the soil, so that the high-temperature steam sprayed from the steam outlet of the nozzle protected by the needle rod penetrates into the soil within a short time, and the high-temperature steam is covered with a cover to become banded steam so as to be prevented from escaping to the outside, thereby increasing the instantaneous temperature of the soil; a mechanical technology that conducts disinfection work while checking all directions of the high-temperature steam soil sterilizer with a video monitor in a cockpit; and a researched and developed mechanical technology in which multi-level thermometers installed on the needle rod is monitored through a temperature monitor in the cockpit, so that the killing temperature of pests, harmful bacteria, and weed seeds is analyzed while watching a status of the temperature of the heated soil.
