WIDE FRONT SPRINKLING-FERTILIZING MACHINE Russian patent published in 2007 - IPC A01G25/09 

FIELD: agricultural engineering, in particular, sprinkling and fertilizing technique in irrigated agriculture.

SUBSTANCE: machine, in conjunction with its anchor driving road track equipped with end reversal stops, is spaced from ground surface by altitude of up to 50 m through on-board supporting toroidal aerostats rigidly threaded by means of rim hubs on on-board water-and-pulp pipeline furnished at perforations from mid portion to ends with water-and-pulp pneumatic ejection-type sprinkling-fertilizing units. On-board, pipe connection, comb-shaped hydrogen and air-ballast collectors laid laterally of on-board water-and-pulp pipeline along the length thereof are adapted for on-board supporting toroidal aerostats furnished with long and short mooring anchoring guide ropes. Two parallel carrier lightning-guiding ropes of annular stays of supporting toroidal aerostat tubular current-conductive puller sleeve are pivotally hung in current-conductive manner from the bottom between both end on-board supporting toroidal aerostats on double-support steel back pin of each pendulum crank, puller sleeve being joined without tension with its out-board telecommunications with on-board tubular current-conductive communications. Rope-road rollers of mechanisms for synchronous front shuttle movement along rope road track are fixed on outer ends of both end tubular constructive parts of on-board water-and-pulp pipeline. Paired wells of airlifts are provided in mid portion of shoulders of each catch of portion to be ameliorated, airlifts being hydraulically, electrically and pneumatically sealed in parallel way from irrigation pump-and-compressor station. Both lower ends of puller sleeve are brought to said wells. Ends of tubular current-conductive telecommunications of puller sleeve, except for annular stays, are freely passed through throat of conductive gauge of hawsehole into well of airlift water-and-pulp pneumatic lift pipeline branched from puller sleeve train is connected to internal well hydrant of airlift. Airlift has chamber permanently filled with water and positioned in airlift base and is further provided with three sluice fertilizer chambers.

EFFECT: increased efficiency of machine by delivering finely dispersed irrigation spray of predetermined intensity or uniformly distributed granulated and liquid fertilizers.
