The present invention relates to a soil sterilizing apparatus, wherein an excavation unit for lifting soil is formed between supports a conveyor is installed at the rear end of the excavation unit to transfer the soil backward a driving unit for circulating the conveyor is installed at any one of the supports a steam generation unit and an infrared device are installed between the supports and a power transmission unit for receiving power from an agricultural machine is installed at the front end of the supports, and thus, the conveyor is circulated by the driving unit to move the soil, which is lifted by the excavation unit, backward, and at the same time, the steam generation unit jets steam to the transferred soil, and the infrared device irradiates infrared light to the soil to sterilize pathogenic microorganisms living in the soil. According to the present invention, the soil sterilizing apparatus can be easily moved to various places to sterilize the soil the steam and infrared light are uniformly applied to the entire soil, which is transferred to evenly spread by the conveyor and then lifted, and thus the entire lifted soil is uniformly sterilized, thereby increasing a pathogenic microorganism sterilization effect the jetting of the steam and the irradiation of the infrared light are simultaneously conducted, thereby promptly sterilizing pathogenic microorganism and the soil in the ground as well as the soil on the ground are simultaneously lifted, so the soil in the ground and the soil on the ground can be sterilized. This sterilization treatment removes pathogenic microorganisms living in the soil, thereby increasing the productivity of crops and improving the reliability of products at the same time.COPYRIGHT KIPO 2016본 발명은 토양살균장치에 관한 것으로서, 지지부 사이에 흙을 끌어올리는 굴착부를 형성하고, 이 굴착부 후단에 흙을 후방으로 이송하는 이송컨베이어를 설치하며, 지지부 중 어느 하나에 이송컨베이어를 순환작동시키는 구동부를 설치하고, 지지부 사이에 스팀발생기 및 근적외선장치를 설치하며, 지지부 전단에 농기계로 부터 동력을 전달받는 동력전달부를 설치함으로써, 이송컨베이어가 구동부에 의해 순환작동되어 굴착부에 의해 끌어올려지는 흙을 후방
