摘要
针对当前甘薯收获时挖掘铲阻力大、破土效果差、降粘效果不佳等问题,设计了一种金蝉仿生甘薯挖掘铲。通过EDEM离散元模拟分析进行了动态模拟研究。结果显示:在分别0.6、0.8、1m/s的运动速率下,仿生挖掘铲受到的阻力显著低于普通挖掘铲。通过进行田间试验,对比挖掘阻力,仿生挖掘铲受到的平均挖掘阻力为5805.3N,普通挖掘铲受到的平均挖掘阻力为6298.4N,仿生挖掘铲与普通挖掘铲相对比减阻效果提高了7.82%。表明仿生金蝉甘薯挖掘铲具有良好的减阻效果,同时在一定程度上具有降低甘薯的破损效果。
In order to solve the problems such as high digging resistance,poor soil breaking effect and poor viscosity reduction during sweet potato harvesting,a golden cicada bionic swwet potato digging shovel was designed.Through EDEM discrete element simulation analysis,dynamic simulation research was conducted on bionic excavator and ordinary excavator,and the results showed that at motion speeds of 0.6,0.8,and 1m/s,the resistance experienced by the bionic excavator was significantly lower than that of the ordinary excavator.Compared with the digging resistance through field experiments,the average digging resistance of the bionic digging shovel is 5805.3N,and the average digging resistance of the ordinary digging shovel is 6298.4N.Compared with the ordinary digging shovel,the drag reduction effect of the bionic digging shovel is improved by 7.82%,which indicates that the bionic golden cicada sweet potato digging shovel has a good drag reduction effect,and to a certain extent,it has the effect of reducing the damage of sweet potatoes.
