EDEM Simulation Study on the Performance of a Mechanized Ditching Device for Codonopsis Planting

Codonopsis pilosula is cultivated mainly in sandy soils, especially the Dingxi area of Gansu province, northwest China. They are planted hilly areas, where large machines cannot reach easily. transplanting has been adopted with a conventional flat planting way, film mulching and seedling outcrops. While its requires opening shallow ditch, short operation cycle, considerable labor intensity demand, simulation analysis was performed according to specific tillage resistance, helpful optimization design later stages improvement domestic ditching plow’s performance. This paper studies performance an adjustable trench plough analyzes orthogonal test Design-Expert response surface data. EDEM software used analyze traction resistance furrow mechanism process. The results show that increased from 1751.31 N 2197.31 as working speed 0.9 m/s 1.5 m/s, 1.25 times higher than former. It indicates had significant effects on resistance. With increase speed, consumed power were considerably. Using stability coefficient depth consistency bottom width indices, angle furrowing impact factors, Box–Behnken experiment method, establishing indices regression model between influence index, comprehensive agronomic requirements MATLAB factor experiment, optimized parameter combination obtained: forward 35° ditch 97.57% 98.03%, respectively. data after comparison can provide reference for small operation.
