SELF-PROPELLED REVERSIBLE TROLLEY WITH HYDRAULIC DRIVE Russian patent published in 2008 - IPC A01G25/09 

FIELD: agriculture.

SUBSTANCE: trolley contains frame with wheels and spade bug interacting with brakes and tips placed on pushers, which are in hinge connection with hydraulic cylinder through T-shaped lever and with selector valve and synchronising system by means of traction system. T-shaped lever links lower lid of drive hydro cylinder with pushers and is provided with upper and lower fixing points displaced in one plane. Lower point is used for pusher fixing while moving in one direction, upper point is used pusher fixing while moving in the other direction. There are holes on pushers to displace tips during their mounting in upper position and at a distance divisible to pusher fixing axes height with regard to each other. If trolley movement direction is changed, tips position is changed to opposite.

EFFECT: simplified design, wide functional possibilities, increased level of unification and decreased operational and reduced costs for sprinkling machines upgrading and production.
