BOOM-TYPE SPRINKLER UNIT Russian patent published in 2004 - IPC

FIELD: agricultural engineering, in particular, mobile drop irrigation equipment.

SUBSTANCE: boom-type sprinkler unit has driving part and two girder extensions pivotally secured to driving part. Each girder extension is made in the form of mutually perpendicular vertical and horizontal girder parts. Left-handed and right-handed parts of girder are equipped with flexible belts, poles and struts. Irrigation heads are mounted on rigid water supplying belt aligned with girder horizontal parts. Driving part is provided with front and rear transverse beams secured on sprinkler unit side members. Left-handed and right-handed extensions of girder are positioned on rear transverse beam so that each of said extensions rotates around vertical axis of rotation of vertical girder. Horizontal parts of girder are connected to front transverse beam through mechanisms for moving said extensions to transport position. Flexible belts are hydraulically communicated with girder vertical extensions and with pump through U-shaped crank by water flow divider.

EFFECT: increased stability of boom-type sprinkler unit in transport position and reduced labor intensity and time for moving girder extensions to transport positions.
