Research and Experiment on Precision Seeding Control System of Maize Planter

Abstract : A precision seeding control system was developed based on GPS, which could achieve real-time adjustment of seeding speed to ensure seed distribution uniformity. Parameters including seeding rate, row spacing and hole number of seed metering device were entered by users which were transferred by CAN bus to the controller. Its electronic speed control system could work out rotational speed of sowing axis matching with operating speed of tractor automatically. Seed metering device was driven by the hydraulic motor. The field experiment results demonstrated that rate of spacing of normally sown seeds and variable coefficient of this system comparing to traditional land wheel driven planter was relatively 94.1 %, 24.6 % and 89.1 %, 33.1 % while operating speed was 5.9 km/h. If the variation range of seeding spacing shrinks 40 % according the standard request, rate of spacing of normally sown seeds of precision seeding control system was 89.7 % exceeded the traditional land wheel 23 %.
