Abstract

Self-propelled self-propelled advance apparatus, of the type comprising a trolley with two wheels and a lance, on which is mounted a first upwardly directed duct, the upper end of which is arranged to receive a spray nozzle, while which at its lower end comprises a mouth for general entry of water; at least one drum designed to receive a hose of great length wound on it, whose inlet mouth is capable of being connected to a source of pressurized water and whose outlet mouth is connected to said general inlet mouth; a hydromechanical propeller group, fed by a second conduit also connected to said mouth of general entrance of the water and provided with a water outlet conduit; a limit stop valve, arranged in said second conduit; a valve for adjusting the advance of the carriage placed in said second conduit; and means for stopping the advance of the carriage, which close the said end-of-stroke closing valve, all arranged so that, at the beginning of the sprinkler irrigation, the hose is unwound and with it the general water inlet is connected. To the pressurized water source and the propeller group begins to make a rotating reel, in which a tractor cable is drawn, the free end of which has previously been fixed to the ground by means of a seal and, when the front end of the spear arrives to the stake, a fixed stop of the tractor cable acts on a bar that actuates the end-of-stroke closing valve, closing it and deactivating the propeller group, whereby the car stops, characterized in that it comprises a body that seen in front elevation it has a narrow width and is equipped with a narrow fairing, comprising a long lower front skate on the ground, and two rear legs, symmetrically arranged with respect to the longitudinal plane. Middle of the apparatus and provided with respective wheels also supporting the ground, each rear leg being of right angle configuration, with a substantially vertical end branch, provided at its free lower end of the wheel, and a substantially horizontal upper transverse branch, telescopically plugged into a tubular portion integral with the body of the apparatus, said upper transverse branch being susceptible to being separated or introduced to a greater or lesser degree into its plugged into the tubular integral portion of the body of the apparatus, which allows to separate or bring the wheels closer with respect to the body and use the device between crops, making it circulate above rows of plants.
