MULTIFUNCTIONAL RAINING MACHINE

摘要

FIELD: agriculture.SUBSTANCE: invention relates to agriculture, namely to watering equipment. Multifunctional sprinkling machine includes fixed support with fixed pipe and rotary bend, sprinkler vehicles, self-propelled trucks with hydraulic drives, distributing valves and drain lines. Distributing valves are connected to pipeline connected with rotary bend. Valves are connected via branch pipe and hydraulically controlled valve, shutoff element with hydraulic drive, hydrorelay with control unit, connected to pressure pipe through orifice with tube of outer protection system. Tube connects series actuating valves, hydraulic drive of hydro-controlled valve, drain lines. Hydraulic drives of dollies are equipped with spray nozzles coming from working fluid dispenser. Dosing unit is made as hydraulic drive with piston. Lower cavity of hydraulic drive is connected to additional pipeline through check valve and dispensing valve. Upper cavity is connected to pressure pipe via controlled two-way valve. Lower cavity has filling valve. Extra pipe is made of polyethylene material and is located in clamps on posts. Posts are rigidly connected with second clamps on machine pipeline. Extra pipe is equipped with saddles. Saddles provide hydraulic connection with distribution valves of hydraulic drive supports, drain valves.EFFECT: reduced metal consumption and higher reliability are provided.1 cl, 2 dwg
