为探明1K-50 型果园开沟机工作参数和双旋耕刀辊结构参数对作业功耗的影响规律,该文建立了分析开沟部件功耗的切土,运、抛土力学模型,得到了开沟部件功耗与整机工作参数、刀辊结构参数以及土壤力学性能之间的函数关系.搭建了基于土槽试验台的开沟部件功耗测试装置,模拟坚实度为 950 kPa 的葡萄园土壤环境,以刀辊转速、前进速度、开沟深度和刀辊型式为试验因素,进行单因素试验和多因素正交试验,测得旋耕刀辊在不同结构和工作参数下的功率消耗,得到影响开沟部件功率消耗的因素主次顺序为刀辊型式＞前进速度＞刀辊转速＞开沟深度,其功耗较优参数组合为采用D3型刀辊,刀辊转速为150 r/min,前进速度为...

1K-50 orchard ditching machine with the characteristics of compact structure and convenient operation and transfer has been developed to use in the low and narrow environment of orchards in southern China, which operated in the way of double rotary tillage wheel structure and reverse rotary cutting of soil. In the application process of 1K-50 orchard ditching machine, it was found that the machine could meet the requirement of maximum ditching depth 0.5 m in orchards with small soil solidity, while in vineyards with large soil solidity, the maximum ditching depth was about 0.2 m, and there was...
