ABSTRACT:
Self-propelled irrigation equipment for large planted areas comprises a three-wheeled vehicle carrying a water distribution pipe supported by a telescopic girder, both girder and pipe extending across the vehicle to both sides. The pipe has evenly-spaced outlet openings which deliver water direct to the ground through flexible hoses open at their ends. Water is supplied to the equipment through a large, flexible hose stretched out on the ground between a fixed supply point and a large drum mounted on the vehicle. The vehicle is moved towards the supply point by means of a hydraulic actuator at a velocity proportional to the water quantity passing through the equipment to the ground, while the drum is rotated by a second hydraulic actuator at a rotational speed sufficient to wind up the hose on the drum at the rate of the vehicle's progress. The two actuators are supplied with water through a rotary vane valve common to both actuators, which is governed by the output signal of a water meter measuring the water passing through the vehicle onto the ground.
