摘　　要：针对元胡收获机药土分离机构复杂、药土难分离等问题,设计了一种振动杆式元胡药土分离装置,并研究了3种不同因素对药土分离率与元胡损失率的影响。以元胡药土混合物为试验对象,以振动频率、筛箱倾角和振动杆排数为试验因素,以药土分离率为试验指标,进行单因素试验,得到各因素对试验指标的影响规律,确定出各因素的较优水平区间;以较优水平区间作为试验因素,进行正交试验设计及方差分析,并以药土分离率最大且元胡损失率最小为优化目标进行参数优化和试验验证。结果表明:最优参数组合为振动频率22Hz、筛箱倾角35°、振动杆排数6排,在此参数下测得药土分离率为94.63%、元胡损失率为2.36%,与理论值相比相对误差分别下降2.237%和9.013%,满足元胡机械化收获要求。In order to solve the problems of complicated separation mechanism and unsatisfactory separation of herbs with soil,a vibrating rod type corydalis tuber with soil separation device was designed,and the effects of three different factors on the herbs with soil separation rate and corydalis tuber loss rate were studied.A single-factor test was carried out to find out the influence of each factor on the test indexes,and to establish the better level interval of each factor;the better level interval of each factor was taken as the test factor to carry out orthogonal test design and result analysis,and the maximum corydalis tuber separation rate with soil and the minimum corydalis tuber loss rate were taken as the optimization target for parameter optimization and experimental verification.The results show that under the optimal configuration of parameters(the vibration frequency,22Hz;the sieve box inclination angle,35°;and the rows of vibrating rods,6)the herbs with soil separation rate and corydalis tuber loss rate are 94.63%and 2.36%,and the relative errors are reduced by 2.237%and 9.013%compared with the theoretical value,respectively,which meets the requirements of corydalis tuber mechanized harvesting.
