The present invention relates to a covering blade for garlic sowers retracted by agricultural machines which is an improvement of a covering blade applied to garlic sowers intended to drive constituents of the sowers using driving force from agricultural machines and retracted by being mounted to the agricultural machines such as cultivators. More specifically, the present invention relates to a covering blade for garlic sowers retracted by agricultural machines which is installed at the front of a plow of the sowers, and is configured to dig soil in front of the plow at an upper side of a garlic seedling-sown sowing groove by rotating with driving force of the cultivator, and apply the soil toward the upper side of the sowing groove to cover up the garlic seedling, thereby making a covering operation precise. In addition, the covering blade is configured to secure durability and low friction resistance with soil when digging up the soil for covering during the covering operation. By attaching a soil removal blade which immediately resolves accumulation of soil attached at the front side of a plow disposed on the back of the covering blade, the covering operation can be favorably conducted.본 발명은 경운기와 같은 농기계에 장치되어 견인되고, 농기계에 장치된 동력을 이용하여 파종기의 구성요소가 구동되게 만든 마늘파종기에 실시되는 복토날을 개량한 것으로 보다 구체적인 것은, 파종기의 쟁기 전방에 설치되어 경운기의 동력을 받아 회전하면서 마늘종자가 파종된 파종홈 상면에 쟁기 전방의 흙을 파서 파종홈 상면을 향해 살포하여 마늘종자를 덮어 주는 복토작업이 정확하게 이루어지고, 복토작업시 복토용 흙을 퍼 올릴 때, 토양과의 마찰저항이 적고 내구성이 담보될 수 있게 복토날을 구성하고, 복토날 후방으로 배치된 쟁기 전면에 흙이 부착되어 쌓이는 현상도 즉시 해소할 수 있게 흙제거날을 부착하여 파종작업이 원활하게 이루어지도록 한 농기계로 견인되는 마늘파종기의 복토날이다.
