标准化果园碎草机作业性能试验

Performance Test of Standardized Orchard Straw Crusher

标准化果园种植要求行间种草,需要定期切割还田。为解决机械化碎草问题,在充分调研的基础上,选择了一种牵引式碎草机进行试验研究。结果表明,果园碎草机3个工作行程的割幅利用率为94.6%;平均作业效率为1.28 hm^(2)/h,油耗为8.4~10.2 L/h;割茬高度平均值为100.6 mm,稳定系数为94.5%。该机可靠性强,能较好灵活地适应果园复杂作业环境,满足果园碎草作业要求。

Standardized orchard planting requires planting grass between rows and regular cutting and returning to the field.In order to solve problem of mechanized mowing,a tractor mower was selected for experimental research on basis of full investigation.Results showed that utilization rate of cutting width of orchard mower was 94.6%in three working strokes,average operating efficiency was 1.28 hm^(2)/h,fuel consumption was from 8.4 L/h to 10.2 L/h,average stubble height was 100.6 mm,and stability coefficient was 94.5%.This machine has strong reliability and can adapt to complex operating environment in orchard flexibly and meet requirements of orchard mowing operation.
