摘要
随着国家对于城市绿化和植被恢复作业的逐渐重视,红松苗木得到了广泛的种植,这带来了较高的经济效益以及生态效益。起苗作业是红松苗木种植过程中的重要环节,为提高起苗效率和保证苗木存活率,设计了一种三片挖土铲式起苗机。依据红松苗圃砂质土壤的特性参数和起苗机的结构参数,分析起苗机在作业时的受力情况;使用ANSYS对起苗装置进行强度和疲劳分析,得到了起苗装置的最大应力、最大变形、疲劳寿命和安全系数,通过分析得出各项参数均符合使用要求。经过试验测试,该起苗机的伤苗率均值为4.59%,低于6%,满足实际作业要求。
With the national attention to urban greening and vegetation restoration,Korean pine seedlings have been widely planted,bringing higher economic and ecological benefits to planters.The seedling operation is an important part of the Korean pine seedling planting process.In order to improve the efficiency of seedling and ensure the survival rate of the seedlings,a three-piece excavator type seedling lifter is designed.According to the characteristic parameters of the sandy soil of the Korean pine nursery and the structural parameters of the seedling lifter,the stress condition of the seedling lifter during operation is analyzed.The maximum stress,maximum deformation,fatigue life and safety factorof the seedling raising device are obtained by using ANSYS to analyze the strength and fatigue of the seedling raising device.The simulation results show parameters meet the requirements of use.After experimental tests,the average rate of seedling injury is 4.59%,which is lower than 6%,which meets the actual operation requirements.
