    • A sowing device having a travelling framework (2) is described, which comprises a storage roll (3) for a seed strip (4) equipped with individual grains (5) of a seed, and an unwinding unit (6) for the seed strip (4) drivable as a function of the travel distance. To ensure a precise deposit of the seed grains (5), it is suggested that a sensor (15) for the individual grains (5) in the seed strip (4) be provided in the area of the seed strip section (14) between the unwinding unit (6) and a ground-proximal deflection roll (8), and a control unit (16), connected on one hand to the sensor (15) and on the other hand to a travel distance encoder (18), activate the drive (17) of the unwinding unit (6) as a function of the difference between the actual location of the seed grains (5) detected by the sensor (15) and a setpoint location predefinable with the aid of the travel distance encoder (18).
    • 描述了具有行走框架(2)的播种装置,其包括用于种子条(4)的储存卷(3),种子条配有种子的单个颗粒(5)和用于种子条的退绕单元(6) (4)作为行驶距离的函数可驱动。 为了确保晶粒(5)的精确沉积,建议将种子条(4)中的各个颗粒(5)的传感器(15)设置在种子条部分(14)的区域之间 退绕单元(6)和地面近侧偏转辊(8)和控制单元(16),一方面连接到传感器(15),另一方面连接到行程距离编码器(18),激活 根据由传感器(15)检测到的种晶粒(5)的实际位置与借助于行程距离编码器预先确定的设定点位置之间的差的函数,退绕单元(6)的驱动器(17) 18)。
