Summary: | The utility model discloses a novel underground fixed hydraulic multilevel lifting rod for sprinkling irrigation. The underground fixed hydraulic multilevel lifting rod for sprinkling irrigation comprises a base, a protective pipe, a multilevel stretchable pipe, a sealing ring, a ball valve and a dismountable nozzle, and is characterized in that the multilevel lifting rod is buried underground for about 30cm, when pressure water passes through, the multilevel lifting rod is raised from underground to certain height above the ground under the thrust action of the water, and the nozzle on the multilevel lifting rod also can work; when sprinkling irrigation is not required, the nozzle and the multilevel lifting rod can fall back to a position which is 30cm below the ground under the action of self weight and the action of a vacuum pump. Therefore, the underground fixed hydraulic multilevel lifting rod for sprinkling irrigation contributes to mechanical cultivation on the ground. |
