摘要： A single disk opener blade is supported for rotation about a horizontal axis offset approximately seven degrees from the transverse direction. A seed tube extends closely adjacent the disk blade forwardly of the rotational axis generally in the shadow of the leading edge of the blade. The tube is angled around the disk blade hub to provide a narrow profile and to reduce the vertical velocity of the material deposited in the furrow. A furrow-firming and blade-scraping extension is connected to the lower end of the tube and extends rearwardly to a location behind the axis. The side of the firming extension is located transversely beyond the shadow of the disk blade to help form one side of the seed trench and to permit the seed to settle in the trench. Depth control structure includes a wheel support arm fixed to one end of the disk blade spindle and a quadrant fixed to the opposite end of the spindle for selectively adjusting the arm. A depth control wheel is mounted on the arm about an axis offset from the axis of the disk blade for rotation against the leading side of the blade to clean the blade, hold down trash and dirt, and provide positive depth control.
摘要翻译：支撑单个盘开启器叶片围绕横向偏移大约七度的水平轴线旋转。种子管通常在叶片的前缘的阴影中沿旋转轴线向前靠近盘片叶片延伸。管围绕盘片轮毂成角度以提供窄的轮廓并且减小沉积在沟槽中的材料的垂直速度。沟槽紧固和刮刀刮除延伸部连接到管的下端并向后延伸到轴后方的位置。紧固延伸部的侧面横向超过盘片的阴影，以帮助形成种子沟槽的一侧并允许种子沉淀在沟槽中。深度控制结构包括固定到盘片主轴的一端的轮支撑臂和固定到主轴的相对端的象限，用于选择性地调节臂。深度控制轮围绕从盘片的轴线偏移的轴线安装在臂上，用于相对于叶片的前侧旋转以清洁刀片，按压垃圾和污物，并提供正的深度控制。
