BOOM-TYPE SPRINKLER UNIT Russian patent published in 2005 - IPC

FIELD: agricultural irrigation equipment used in mobile sprinkler units.

SUBSTANCE: boom-type sprinkler unit has frame made in the form of three-dimensional construction composed of pipes and mounted on vehicle equipped with pumping unit. Flexible water pipeline with sprinkling apparatuses is secured on frame by means of cables. Flexible water pipeline is made sectioned. Each section has flexible pipeline segment positioned on carrier member made in the form of pair of longitudinal supports having bent C-shaped profile and flat rings at their end portions. Wide strips of pair of bent C-shaped profile are arranged at an angle to horizontal plane and perpendicular to one another. Said profiles define, in conjunction with rings, trough of carrier member. Adjacent carrier members are connected with one another by means of connecting parts through spacer bushings. One, two or three spacer bushings are made in the form of brackets for connecting cable ends to join with frame. Ends of flexible pipeline segments are mutually joined via transition portion made in the form of bushing. Ends of transition member have conical entrance portions. Annular portion formed on transition member surface is joined with ends of adjacent segments and pairs of yokes on their surface. Cable ends joining brackets are equipped with eye ring receiving slots and mounting openings. Diameter of carrier member rings exceeds outer diameter of transition member by 1.5-1.9 times.

EFFECT: simplified construction and increased efficiency.
