The present invention relates to an electric rotary tilling device for elevated cultivation field, comprising: a housing shaped like a box； an axle coupling pipe coupled to each of the front and back of the bottom of the housing； a wheel part including an axle in which a pulley-type wheel is coupled to one side by means of a shaft and a side support, and the other end is inserted into both ends of the axle coupling pipe； a driving motor connected by a driving line and having the partition installed therein； a rotary shaft installed via the ball bearings installed on the side plate and installed so as to be rotatable by receiving power from the driving motor through a transfer means； and a rotary part coupled to the rotary shaft, wherein the electric rotary tilling device is configured so as to be capable of performing a rotary operation while automatically moving forward on an elevated cultivation field rail, a pinhole is formed in the axle, a slot is formed lengthwise on both sides of the axle coupling pipe, the axle is inserted into the axle coupling pipe, after which the pin is coupled while inserted in the pinhole such that the wheel part can handle changes to the interval of the rail, the rotary part further includes a rotary blade, a rotary hub on which are formed a plurality of rotary insertion protrusions, and a fixing bolt, and the rotary blade may be replaced to easily adjust the depth of the rotary operation. A shutdown switch protruding from the upper portion of the front of the housing and a shutdown plate installed on the end of the rail are synchronized such that when the rotary operation is completed, the driving motor is automatically shutdown.본 발명은 고설재배장치용 전동경운기에 관한 것으로, 사각형 박스 형태의 하우징, 상기 하우징의 하부 전방과 후방에 각각 결합된 액슬결합파이프, 풀리형 바퀴가 굴대와 측면지지대에 의해 일측에 결합되고 타측이 상기 액슬결합파이프 양단에 삽입되는 액슬을 포함하는 바퀴부, 구동 전력선에 의해 연결되어 상기 칸막이 내부에 설치된 구동모터, 상기 측판에 설치된 볼베어링을 매개로 설치되고, 전달수단에 의해 상기 구동모터의 동력을 전달받아 회전가능하게 설치된 로터리 회전축； 및 상기 로터리 회전축에 결합된 로터리부로 구성되어, 고설재배장치용 레일 위에서 자동으로 전
