Abstract:
1. A sowing device having a travelling framework ( 2 ), 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, wherein a sensor ( 15 ) for the individual grains ( 5 ) in the seed strip ( 4 ) is 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 to the sensor ( 15 ) and to a travel distance encoder ( 18 ), activates the drive ( 17 ) of the unwinding unit ( 6 ) as a function of the difference between an actual location of the seed grains ( 5 ) detected by the sensor ( 15 ) and a setpoint location predefinable via use of the travel distance encoder ( 18 ).
