马铃薯堆垛机增高减损设计与试验
Design and experiment on height increase and damage reduction of a potato stacker
摘要
Abstract
Potato stacking constitutes a crucial procedure for warehouse storage.At present,the mechanization and automation levels of domestic potato stacking operations are relatively low.Conventional stacking equipment suffers severe drop impact and high tuber bruising rate under the working condition of high potato piles,and relevant researches on dynamic height adjustment and low-damage parameter optimization are insufficient.Therefore,the optimal design and experiment of a height-adjustable potato stacker for damage reduction were carried out in this study.The stacker is equipped with a liftable discharging mechanism that modulates the vertical distance between the discharge outlet and the potato pile in real-time,thereby reducing the free-fall distance and impact energy,which controls injury rates while maintaining high stacking efficiency.Key structural parameters affecting operation performance were screened via theoretical analysis,and core components of conveyor belts and supporting rollers were optimally designed.The EDEM discrete element simulation technology was adopted to conduct structural verification.Conveying speed,vertical distance between the end of discharge outlet and potato pile,and feeding rate were selected as test factors,while stacking efficiency and tuber bruising rate were taken as evaluation indices,and a quadratic orthogonal rotation combination test was implemented.A second-order response surface model was established by Design-Expert software,and the desirability function method was used for multi-objective optimization.Combined with actual on-site production demands,the weight of stacking efficiency was set to 0.6 and the weight of tuber bruising rate was set to 0.4.The optimal parameter combination was as follows:conveying speed of 0.56 m/s,vertical distance of 184.46 mm between discharge outlet and potato pile,and feeding rate of 26.96 t/h,corresponding to a stacking efficiency of 24.80 t/h and a tuber bruising rate of 0.61%.The verification test results showed that the error of stacking efficiency was 0.29 t/h and the error of tuber bruising rate was 0.04%.The measured values wereclose to the optimized predicted values,which proved that the optimized parameter combination had favorable applicability.The research results can provide technical references for working condition regulation and low-damage operation of potato warehouse stacking equipment.关键词
