PRECISION SEEDER

The invention relates to a control and regulating device (1) for a precision seeder, comprising a plurality of driven precision seeding appliances (2) respectively comprising a separate drive motor with a rotary pulse generator for each individual appliance (2). A regulator is used to control each drive motor, said regulators being embodied in such a way that they can be supplied with a control signal of a coupling calculator (4). Whereas, in prior art, the regulators are placed centrally in the coupling calculator (4), the regulators according to the invention are decentralised on the precision seeding appliances and are connected to the coupling calculator (4) embodied as a control unit, by means of signalling lines (3). Furthermore, each appliance (2) respectively comprises its own decentralised regulating unit (2.1) comprising a regulator and a control loop. The regulators are embodied in such a way as to convert the non-transformed path-dependent or speed-dependent signal emitted by the coupling calculator (4) into activating signals for the associated drive motors.
