Design and Finite Element Analysis of Pre-pushing Double-cone Rotary Dredging Device in the Yellow River Irrigation Areas

Abstract

In view of sediment deposition in the yellow river irrigation areas, a new pre-pushing double-cone rotary dredging device is described in detail in the paper, and the main structure is analyzed by finite element method. By hydraulic-driving technology and rotary stir-scour principle, the device can stir sediment deposition at the bottom of channel to turn into turbid muddy water, which can be washed away by water flow to complete dredging operation of irrigation channel.
