FIELD: agricultural engineering, in particular, sprinkler machines movable around central support.
SUBSTANCE: sprinkler machine has fixed support, self-propelled carts provided with hydraulic cylinders, and water feeding pipeline with sprinkler units. Bracket is fixed to cart power lever. Tips of front and rear pushes are equipped with additional tips. Wheel stops are provided with main and additional brakes and springs. Central angle between main and additional brakes is 125 deg. Main and additional speed regulators positioned on carts, except for terminating cart, are connected through tie-rods with water feeding pipeline. Water is fed from water feeding pipeline to speed regulators through inlet pressure hoses. For actuation of main and additional speed regulators, spherical valves connect outlet pressure hoses with hydraulic cylinder. Additional guides are mounted on cart. Actuation valves mounted on main and additional speed regulator are provided with hydraulic emergency protection pipes.
EFFECT: provision for reversing motion, simplified construction and enhanced reliability in operation of sprinkler machine.
