摘要： A device for placing seed into the soil at a specific pitch in which radiating spikes of two star wheel formed discs (6,7) are brought together by rotating the discs (6,7) synchronously at an angle and that each of the radiating spikes has on its inner side a hollow channel forming an internal closed funnel (3) when the spikes are brought together and opens when by further rotating the spikes move away from each other. The means to place seed or small objects into the funnels (3) consists of a hub (2) disposed about the axis of rotation of the discs (6,7) and mounted to rotate with the discs (6,7), which hub (2) is provided with cells adapted to receive the seed or the other small objects and to release them upon rotation of the discs (6,7) so they can fall under gravity into the funnel (3).
The device is particularly suitable to plant seed into soil covered by a thick crop residue.摘要翻译： 用于以特定节距将种子放置在土壤中的装置，其中两个星形轮形成的盘（6,7）的辐射尖峰通过以一定角度同步地旋转盘（6,7）而聚集在一起，并且每个辐射尖 在其内侧具有形成内部封闭漏斗（3）的中空通道，当尖峰被带到一起时，当通过进一步旋转尖峰彼此远离时，它们打开。 将种子或小物体放置在漏斗（3）中的方法包括围绕盘（6,7）的旋转轴设置并安装成与盘（6,7）一起旋转的轮毂（2），该轮毂 （2）设置有适于接收种子或其他小物体的细胞并且在盘（6,7）旋转时将其释放，使得它们可以在重力作用下落入漏斗（3）中。 该装置特别适合将种子种植在被厚重作物残留物覆盖的土壤中。
