A sprinkling machine includes a water-supply belt arranged on a self-propelled supporting carriage and vertical supporting pipes fixed thereon with wing-wall girders, on which sprinkling units are mounted. The vertical supporting pipe with the wing-wall girders are hingedly fixed on the water-supply belt as regards to the vertical axis with the aid of joint couplings. In doing so the wing-wall girders are connected with a hydraulic cylinder and a hydraulic switcher, and the latters are kinematically connected with the vertical supporting pipes and the wing-wall girders by a system of levers and ropes through the joint couplings. |
