DEVICE FOR ADJUSTMENT AND CONTROL OF RATE OF FLOW OF SEEDS AND MINERAL FERTILIZER Russian patent published in 1995 - IPC

Abstract RU 2043007 C1

FIELD: agriculture. SUBSTANCE: device has a flow rate sensor mounted under the seeding unit. The sensor has two insulated plates in a signal-forming circuit connected to the device control unit. The latter is based on a microcomputer. By means of its input/output port and two power amplifiers the microcomputer is connected to a solenoid valve and a motor linked with a throttle. The valve and throttle are parts of the tractor hydraulic system, and they are connected to a hydraulic motor mounted on the seeding unit shaft. EFFECT: higher efficiency; more accurate control. 9 dwg
