Abstract

Irrigation apparatus comprises a movable vehicle arranged to be steered along a required ground path and carrying a pair of laterally-extending booms each of which is pivoted to one side of a rotatable turret mounted on the vehicle chassis. Each boom carries spray or sprinkler nozzles spaced along their lengths and one or more spray nozzles at its tip, all connected to a supply of water, and the spray patterns of the various nozzles overlap one another in such a way as to ensure even total dosage of water delivered per unit area of ground as the machine advances. Means is provided for angularly reciprocating the turret and booms about the vertical axis of the turret. The vehicle may be connected by a trailing flexible hose pipe to a hydrant, or may have a power-driven hose reel on which the hose is wound and by which it can can be reeled in or unreeled whilst the vehicle is moving and with the hose either empty or delivering water. The flexible hose may also be of a longitudinally-seamed construction. The vehicle may alternatively run along a water-filled canal and pick up water from the canal as it moves.

Dependent claims

A land irrigation machine which comprises a self-propelled steerable vehicle which can be driven and steered in a direction of forward movement along a required path on the ground while connected to a supply of water through a flexible hosepipe, the vehicle comprising

a. a steerable carriage having a water inlet for connection to the hosepipe,
b. a generally horizontal elongated boom structure pivotally mounted on the carriage, said boom structure comprising two elongated sprinkler arms which are disposed transversely to the direction of forward movement of the vehicle and extend respectively on opposite sides of the carriage over a distance several times greater than the width of the carriage, each of said arms carrying a plurality of fixed water sprinklers distributed along the length of the arm, each of said sprinklers being connected to be supplied with water from the water inlet and to deliver the water in droplet form onto the ground in respective areas which overlap one another,
c. means for pivotally mounting said arms for oscillation in alignment with each other about a vertical pivot axis, and
d. means for decreasing the rate at which the water from said water inlet is distributed to the ground without decreasing the volume of water being supplied to each segment of the ground, said means including power means for continuously oscillating said arms about said vertical pivot axis while water is being delivered through said water sprinklers onto the ground alongside the vehicle during the forward movement of the vehicle along said path.
