FIELD: agriculture. ^ SUBSTANCE: invention is related to agriculture, namely to sprinkling machines, which move frontally. Sprinkling machine comprises trolleys including frame, cord support, short pipe. Between trolleys there are spans of water supply pipeline mounted, which consist of two extreme pipes and single intermediate pipe, on which deflector nozzles of full-circle irrigation are installed. Deflector nozzles of part-circle irrigation are installed at lean-tos of short pipes in trolleys. On short pipe of the first trolley there are the following components fixed serially: adapter and discharge flexible hose with connector. Column is fixed on hydrant of closed irrigation network. On trolley power lever there are front and back pushers mounted, as well as bracket, to which additional front and back pushers are fixed. Main and additional guides are installed on trolleys, being equipped with rollers, and as pushers are installed on them, they are disengaged with wheels. On the main and additional speed controllers there are servovalves mounted, which are connected by hydraulic tube serially to each other, and also with stop valves of the first and last trolley and with nozzle installed on adapter. Sprinkling machine provides for irrigation in process of motion of rectangular sections during frontal displacement with high coefficient of land usage (LUC=0.96Ç0.98). Deflector nozzles of full-circle and part-circle action generate atomised and erosion-safe rain. ^ EFFECT: reduced working hours required to changeover machine from forward motion to reverse motion, provision of simultaneous frontal motion of machine and irrigation, simplified design. ^ 3 dwg |
