Simulation of Deep Tiller Rotary Blade Cutting Soil Based on Finite Element Method
Soil leakage and heavy tillage and straw wrapping,an innovative rotary knife roller for deep tillage machine was designed.The equivalent stress distribution of cutting soil is obtained by simulation.It is found that the disturbance displacement of shallow soil is the biggest,next is middle soil and deep soil.The simulation results are consistent with the actual planting conditions.The rotary tiller roller designed for deep tiller can play the greatest role in cutting soil,reaching the design goal of cutting,loosening and throwing soil.This will improve soil quality to meet the needs of crop cultivation.In addition,the designed rotary tiller also provides a new idea and method for the till-age parts of deep tiller,and effectively solves the problem of heavy tillage and leakage tillage.
