双螺旋对辊式赤芍种夹收获装置设计与试验OA

To address issues such as the flexible texture of red peony roots,their strong adhesion to straw,and the high labor intensity and inconsistent results of manual harvesting,a dual-spiral counter-rotating roller red peony root har-vesting device was designed and developed.Focusing on the spiral guidance and clamping-separation mechanism of the counter-rotating rollers,an analysis was conducted on the coordination between structural parameters(pitch,diameter,spacing,etc.)and operational parameters(forward speed,roller rotation speed).Two response metrics were meas-ured:harvesting completeness rate and damage rate.Results from secondary model fitting indicated:R2y1=0.98、R2y2=0.98.Multi-objective optimization using an objective function yielded the optimal parameter combination,achie-ving approximately 98.67%completeness rate and 3.97%damage rate under this configuration.The research results demonstrate that the developed device can achieve high harvesting purity,low damage rates,and stable operation under typical Paeonia lactiflora cultivation conditions.This provides equipment and parameter references for the mechanization and large-scale production of Paeonia lactiflora harvesting.
