COVERING MACHINE FOR AGRICULTURE

The present invention relates to a covering machine for an agricultural machine, in which a rotary is varied and corresponds to the inside and outside of a covering machine according to conditions of a work site, a condition of crops, and a condition of furrows, so that a mechanical operation may be carried out. Accordingly, the present invention can maximize work efficiency while reducing worker fatigue. More specifically, the covering machine for an agricultural machine includes: a covering machine frame composed of a front bar and a rear bar provided at the rear of the front bar and connecting opposite ends with a blocking plate; an upper link and a lower link, which are at the central position of the covering machine frame and protrude to the front side so as to connect to an agricultural machine; a gear box, which is at the lower side of the center of the covering machine frame, and is installed to receive power from the agricultural machine to connect a driving shaft to opposite sides; a left rotary mounting device and a right rotary mounting device, which are at opposite sides of the covering machine frame and connects and couples, by using an interval maintaining bar, both sides of a front maintaining pipe accommodating the front bar and a rear maintaining pipe accommodating the rear bar; a rotary case which constitutes a left rotary and a right rotary each having a rotary blade mounted on the lower side thereof, is connected to the driving shaft, and is mounted between the interval maintaining bars; auxiliary wheels mounted on the front side of the front maintaining pipe constituting the left and right rotary mounting devices; a supporter protruding to the rear side of the rear maintaining pipe to connect a rotary cover; and a rotary varying means which varies the left and right rotary mounting devices to the inside and outside of the covering machine frame, so that the left and right rotaries correspond according to a width or interval of a furrow. 본 발명은 작업지의 여건이나 농작물의 상태 및 이랑의 상태에 맞게 로터리를 복토기프레임의 내,외측으로 가변시켜 대응하도록 하면서 기계적인 작동에 의하여 이루어지도록 함으로서 작업자의 피로도를 경감하면서 작업 효율성을 극대화할 수 있도록 한 것으로서; 프론트바와, 프론트바의 후방에 구비되고 양단을 차단판으로 연결한 리어바로 구성되는 복토기프레임과; 상기 복토기프레임의 중앙 위치에 농기계와 연결할 수 있도록 전방으로 돌출되는 상부링크 및 하부링크와; 상기 복토기프레임의 중앙 하방에 농기계로부터 동력을 전달받을 수 있도록 설치되어 양측으로 구동축을 연결하는 기어박스와; 상기 복토기프레임의 양측에 프론트바를 수용한 프론트유지관과 리어바를 수용한 리어유지관의 양측을 간격유지바로 연결하여 결합하는 좌측로터리장착기 및 우측로터리장착기와; 하방에 로터리날을 장착한 좌측로터리 및 우측로터리를 구성하고 구동축과 연결되며 간격유지바 사이에 장착되는 로터리케이스와; 상기 좌,우측로터리장착기를 구성하는 프론트유지관의
