WHEEL SPRINKLING PIPELINE Russian patent published in 2008 - IPC A01G25/09 

FIELD: agriculture.

SUBSTANCE: wheel sprinkling pipeline contains the extended spigots installed on the pipeline in places of joining of basic wheels, and these spigots are fast connected to the pipeline and with basic wheels. On each extended spigot fitted on the rotary spigot with twirl possibility on which stabilizer blades and a counterweight serving for orientation of stabilizer blades concerning a ground surface are fixed. One end of the rotary spigot is gear for cogging with the spigot-slide block, fitted on the extended spigot with up-and-down motion possibility on it. The spigot-slide block by means of a spring is spring-loaded concerning the extended spigot. The spigot-slide block end turned towards the rotary spigot and it is executed in the form of the frustum of a cone which smaller basis has teeths for the clutch with the gear end of the rotary spigot. For the drive of stabilizer blades on the extended spigot two hydrocylinders which stocks are connected to the spigot-slide block are symmetrically fixed. Thus the rotary spigot is supplied by two arms on which the horizontal axes are fixed hinged and they fast connected to levers having spherical support, contacting to external walls of a cone part of the spigot-slide block. Horizontal axes are fast connected with stabilizer blades which are connected among themselves by means of the return spring fixed on bars, that are placed on the top part of stabilizer blades. And, as stabilizer blades are fast connected through horizontal axes with levers that due to the return spring pressing of the spherical support to external walls of a cone part of the spigot-slide block which have been placed on the ends of levers is also provided. The stabilizer blade is executed in the form of the lever in which bottom part the pointed core is fixed that is supplied with a basic disk which provides a load dispatching that outgo from the stabilizer blade on a ground and interferes with that to a stabilizer blade lowering in soil. Rods on which the counterweight is fast fixed are hinged connected to horizontal axes. Cavities of hydrocylinders by means of flexible conduits are connected with a main connected to a strut of the sprinkler. Invention use will allow preventing completely spontaneous overrolling of the wheel sprinkling pipeline at wetting. As the wheel sprinkling pipeline during all wetting process will be fixed in some position that will prevent its spontaneous overrolling in both directions at affecting on it of a wind load or at its use for irrigation of inclined sections.

EFFECT: raising the productivity due to time abbreviation on moving the wheel sprinkling pipeline on a new position.
