SPRINKLER UNIT Russian patent published in 2005 - IPC

FIELD: agricultural engineering, in particular, sprinkling irrigation of farm crops.

SUBSTANCE: apparatus has supporting members made in the form of cables attached in cantilevered manner to frame top, and irrigation pipeline connected to vehicle through pumping unit. Irrigation pipeline is coupled to frame by means of carrier carcass. Irrigation pipeline and carrier carcass are made sectioned. Each carrier carcass section is defined by pair of C-shaped bent profiles with flat rings at their ends. Profiles are arranged at an angle to one another with their wide strips to define trough. Sections of flexible pipelines made from low-pressure polyethylene are laid on trough. Ends of pipelines are embraced with bands made in the form of steel bushings. Ends of pipelines are joined by means of adapter member. Input parts of connecting member are made conical. Each adapter member is formed as hollow screw with left-handed and right-handed conical threads on their outer surface. Mid portion of screw has disk for fixing irrigation pipeline sections in operating position in rings of carrier carcass by means of paired spacer bushings and attachment means. Disk of adapter member is equipped with group of openings used for assembling-dismantling works. Openings for connection to threaded ends of cables are made in peripheral portions of carrier carcass flanges.

EFFECT: uniform distribution of precipitation in the form of rain drops through width of mobile unit, reduced material usage, simplified construction, and enhanced reliability in operation.
