DEVICE OF AUTOMATIC CONTROL OF MULTISUPPORTING IRRIGATION MACHINE OF FRONT ACTION Russian patent published in 2013 - IPC A01G25/09 

FIELD: agriculture.

SUBSTANCE: device comprises pipelines of right and left wings of the machine, a unit of movement synchronisation along the course and control unit of the machine speed. The pipelines of the right and left wings of the machine are mounted on electric shuttles. The unit of movement synchronisation along the course comprises a guide wire. Along the irrigation channel on the racks a contact network is mounted, interacting with the current collector. The current collector through the telescopic mechanism is mounted on the shuttle. The shuttle moves on the opposite side of the irrigation channel. The current collector output is connected to the input of the control panel. The control panel output is connected to the input of electric power meter. The outputs of the electric power meter are connected to the inputs of the contactor, the microprocessor control unit, and the frequency converter. The inputs of the microprocessor control unit are connected to the timer, the course stabilisation system, the system of the shuttles synchronisation in line, the distometer, the irrigation norm setter, the setter of the irrigation length section, the flow meter, and the pressure gauge. The pressure gauge is mounted on the pipeline. The outputs of the microprocessor control unit are connected to electric hydraulic valve, frequency converter, contactor, devices of the shuttles synchronisation in line and devices of stabilisation of the left and right wing course. The outputs of the microprocessor control unit are connected via a vacuum pump to the pump input. The pump output through the electric hydraulic valve the flow meter is connected to the pipeline. The microprocessor control unit is connected to the input-output of the interface device. The signal from the output of the frequency converter is set to the electric drive of the left and right wing of the machine. The output of the contactor is connected through the electric motor to the pump input.

EFFECT: construction enables to improve the quality of irrigation and environmental friendliness of energotechnological process of irrigation.
