AUTOMATED UNIT FOR DIFFERENTIATED INTRODUCTION OF LIQUID MINERAL FERTILIZERS Russian patent published in 2018 - IPC A01C23/00 A01C23/04 A01C23/02 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural engineering and can be used when equipping machines for applying liquid mineral fertilizers. Automated unit includes energy tool (1), sectional tank (2) for applying liquid mineral fertilizers, speed sensor (3), intake filter (10), centrifugal pump (11), actuator unit. Actuator unit consists of pressure regulating valve (12), flow meter (13), exhaust section valves (9), rods with nozzles (21), block inlet section valves (9), pressure sensor (15) with processing unit (16), stepper motor (18) with control circuit (19), controller with video terminal (5), flash memory (7) and navigator (6), frequency input module (4), discrete output module (8), main channel (20). Unit is equipped with sensors of the minimum liquid level (22–26) in tank sections (2) for the application of liquid mineral fertilizers, discrete input module (27), the inputs of which are connected to the sensors of minimum liquid level (22–26), with output via RS-485 interface connected to controller (5) and mobile communication module (28).

EFFECT: improved fertilizer application.
