1. A mobile drip irrigation device having a water distribution conduit supported by a truss structure and motorized towers for movement above soil and having a plurality of elongated drip tubes operatively connected at their forward ends to receive water supplied from the water distribution conduit and to contact and move over the soil during movement of the mobile drip irrigation device, each drip tube including a plurality of ports formed through the drip tube at predetermined intervals along the length of the drip tube to emit the water from the ports directly onto the soil to irrigate plants growing in the soil, the mobile drip irrigation device further comprising:
an anchoring and retention structure which operatively retains the forward ends of the drip tubes at substantially fixed predetermined positions below the water distribution conduit and above the soil, the predetermined positions establishing relatively fixed intervals of spacing between the forward ends of the adjacent drip tubes; the anchoring and retention structure retaining the forward ends of the drip tubes against substantial movement away from the predetermined positions in directions both perpendicularly and longitudinally relative to the water distribution conduit; the anchoring and retention structure including at least one guide member operatively retaining the forward end of each drip tube to the truss structure to retain the forward end of the drip tube against substantial perpendicular movement relative to the water distribution conduit, and the anchoring and retention structure operatively pulling the drip tubes from their forward ends to guide the drip tubes across the soil and through the plants during movement of the mobile drip irrigation device. |
