原始语种摘要: Abstract(#br)To reduce the resistance and energy consumption of disc furrow openers, biomimetic coupling disc furrow openers (BCDFOs) that were inspired by digging animals (e.g., the convex hull of a dung beetle pronotum and the back-ridge scales of a pangolin) were designed as biomimetic coupling elements. The resistance of BCDFOs, analyzed by the discrete element method, was less than that of the common flat disc furrow opener (CFDFO). The effects of different structures on soil disturbances in the forward and lateral directions were analyzed. The soil swelling rate and soil disturbance coefficient were calculated to evaluate the soil disturbance characteristics. Three less resistant BCDFOs were manufactured and tested in soil bins with different working conditions (furrow speed = 0.6,...
