摘要
A viscosity driving device for a lifting buried spraying head includes a cylindrical case (2), a filter (3) provided in the lower end of the case (2), and a spraying head driving unit disposed inside the case (2). The spraying head driving unit is connected with a spraying head positioned on the top end of the case (2) by means of a connecting shaft, and the spraying head driving unit drives the spraying head to rotate and spray water. The spraying head driving unit comprises a tangential flow generator (4) and a hydraulic rotator (5), and the hydraulic rotator (5) rotates under the action of viscosity of rotating water generated by the tangential flow generator (4) to drive the spraying head to rotate and spray water.
