SELF-PROPELLED REVERSING CART FOR MULTITOWER SPRINKLING MACHINE Russian patent published in 2006 - IPC A01G25/09 

Abstract RU 2287262 C1

FIELD: agricultural engineering, in particular, self-propelled multitower sprinkling machines adapted for intake of water from pressure pipelines.

SUBSTANCE: self-propelled reversing cart has frame with pair of carrier wheels and brakes, hydraulic drive cylinder equipped with piston and connected with distributing unit through distributing valve and regulating valve connected to two-way synchronization mechanism, forward and backward stroke tips mounted on pushers of front and rear wheels and cooperating with ground-engaging means, additional distributing valve located in feeding line of hydraulic cylinder lower cavity and adapted for providing alternative communication of said cavity with pipeline of sprinkling machine and atmosphere. Water is fed simultaneously into main and additional distributing valves from pressure pipeline by means of T-pipe. Piston is furnished with two collars having thrust washers arranged at both sides in opposite orientation with respect to one another and located for sliding on upper part of hydraulic cylinder stem, said sliding motion being restricted in lower position by rib and in upper position by tightening nut. Hydraulic cylinder stem has sealing member positioned in lower part of hydraulic cylinder casing. Stem 7 of distributing valve and stem 24 of additional distributing valve are joined with their lower parts through threaded connection by means of bushing. Ground-engaging means is made in the form of hollow square with oval-shaped working surfaces engageable with forward and backward stroke tips arranged at left-hand and right-hand sides of pushers in the vicinity of their leading end and connected therewith through pivot joints, which are fixed at forward and backward stroke by means of front and rear splints.

EFFECT: increased efficiency by reducing power consumed for conversion of machine motion from forward stroke to backward stroke.
