Abstract

Self-propelled advance sprinkler device, including a carriage with two wheels and a lance, on which is mounted an upwardly directed duct, the upper end of which is arranged to receive a sprinkler nozzle, while at its lower end it comprises a general water inlet key; a drum designed to receive a hose wound on it, of great length, whose entrance mouth is susceptible to being connected to a source of water under pressure and whose outlet mouth is adapted to be plugged into the general inlet disposed at the base of the cited duct directed upwards; a hydro-mechanical propeller group; and a stop device that closes the general water inlet key or disconnects the propeller group, characterized in that said hydromechanical propeller group comprises a hydraulic turbine, a speed reducer and torque multiplier, a support plate, a lever, a connecting rod, a ratchet mechanism and a toothed wheel integral with the axis of the spool in which the tractor cable is wound, all arranged so that said hydraulic turbine is driven by the water that under pressure passes through said pipe directed upwards, being driven by the turbine, said speed reducer and torque multiplier, which in turn acts on the support plate, on which the lever is mounted, provided with a tang and posibionable in several positions so that said tang, which constitutes the articulated joint point of one end of the connecting rod travels in the rotation of the plate-support different circumferential trajectories of different radius, depending on the greater or less the decentration of said pin with respect to the center of rotation of the support plate, the connecting rod disposed at its other end by the ratchet mechanism acting on the cog wheel integral with the axis of the trailing cable winding reel.
