APPARATUS FOR CONSTRUCTING IRRIGATION SYSTEMS Russian patent published in 2003 - IPC

FIELD: agricultural construction equipment. SUBSTANCE: apparatus has moldboards equipped with shares and fixed on girders symmetrically mounted on left- hand and right-hand sides of frame at an angle α of 45-48 deg to frame longitudinal axis. Girders are connected to mechanisms for setting share cutting angles γ within the range of 84-96 deg. Beveled plates of ridge former are mounted on frame. Compaction roll has adjustable weight. Depth of cut layer is regulated by means of carrier wheel raising and lowering mechanism. Wheels are mounted on frame and girder ends for free movement in vertical plane during ridge formation. Apparatus is hitched to tractor and to its hydraulic system, which is connected to hydraulic cylinders for moving apparatus to operating or transport position. During advancement of apparatus cut soil layer is moved over moldboard to central part of apparatus under plates of ridge former and compaction roll. Ridge formation is effectuated at floating position of hydraulic system. EFFECT: increased efficiency and improved construction quality of irrigation systems. 5 cl, 7 dwg
