    • A seed drill includes a novel planting assembly combining press wheels for packing angular sides of a furrow and a runner immediately behind and longitudinally aligned with the press wheel. The runner extends rearwardly from beneath the press wheel and is transversely guided on the press wheel structure or frame of the drill to maintain it in longitudinal alignment within an open longitudinal slot cut through the soil and intersecting the base of the packed furrow. Seed is dropped into the open slot prior to being covered with soil. Moist soil can be packed along the sides of the furrow to maintain the furrow in an open condition during seed germination and plant emergence. Highly accurate planting depth control can be achieved, with provision for upward relative movement of the runner as required by encountered field conditions.
    • 种子钻包括一种新颖的种植组合,其组合用于将犁沟的角边和紧靠在后轮纵向对齐的滚轮的滚轮组合。 转轮从压轮下方向后延伸,并横向引导到钻头的压轮结构或框架上,以使其在穿过土壤切开的开放纵向狭缝内纵向对齐,并与填料沟的底部相交。 在被土壤覆盖之前,将种子落入开放的槽中。 在种子萌发和植物出苗期间,可以沿着沟的侧面包裹湿润土壤以保持沟槽处于开放状态。 可以实现高精度的种植深度控制,根据遇到的田间条件的要求提供跑步者的向上相对运动。

    • A seed drill including depending furrow openers having a lower shovel and a supporting seed boot. Each seed boot is pivotally supported on a longitudinal drag bar assembly connected to it about a transverse pivotal connection. The forwardly extending arm at the upper end of the seed boot selectively engages one end of a longitudinal leaf spring mounted to the drag arm assembly. A preselected planting position for the shovel and seed boot is defined by an overlying adjustable stop. An arcuate abutment surface is interposed between the seed boot arm and leaf spring. A stop is interposed between the drag arm assembly and leaf spring for limiting upward movement of the free spring end.
    • 一种种子钻,包括具有较低铲的相对的开沟机和支撑种子靴。 每个种子靴枢转地支撑在围绕横向枢转连接件连接到其上的纵向拖杆组件上。 在种子靴的上端处的向前延伸的臂选择性地接合安装到牵引臂组件的纵向板簧的一端。 用于铲铲和种子靴的预选种植位置由覆盖的可调节限位限定。 在种子靴臂和板簧之间插入弧形邻接表面。 牵引臂组件和板簧之间夹有止动件,用于限制自由弹簧端部的向上运动。
