FIELD: agriculture. ^ SUBSTANCE: invention is related to device (1) for control and adjustment of single-grain feeder with group of single-grain sowing apparatuses (2), every of which has driving motor, detector of rotation pulses and adjustment facility (2.1). Adjustment facility (2.1) has controller and control circuit for control of driving motor. Controllers are joined by means of signal lines (3) to control facility (4), which represents a computer and sends control signal via signal lines to controllers. Adjustment facilities (2.1) are arranged with the possibility to transform non-transformed signal that arrived from central computer (4) and depends on route or speed, into control signals for according driving motors. Each single-grain sowing apparatus is equipped with sowing disk with detector of synchronisation of separate sowing disks with each other. At the same time detector of sowing disk is arranged with the possibility to detect disk rotation. ^ EFFECT: invention makes it possible to execute more accurate and flexible adjustment of sowing apparatuses, simple replacement of sowing disks, synchronise operation of sowing apparatuses, to reduce number of signals and amount of information, which should be sent to signal lines between control facility and sowing apparatuses. ^ 8 cl, 1 dwg |
