微耕机土壤耕作部件田间测试平台的研制

Development of field test platform for tillage components of micro–cultivator

针对室内土槽试验难以真实模拟田间试验的工作状况,在SR1Z–135型多功能微耕机的基础上,研制了微耕机土壤耕作部件田间测试平台。该平台由传动系统、测试系统、试验系统和行走系统组成,可在田间实际工况下对旋耕刀、深耕刀、防缠刀和起垄器进行性能测试,并实时显示和处理这些待测部件的转速、转矩及功率信息。田间验证试验结果表明:微耕机旋耕刀组平均转速为47 r/min时,平均转矩为226 N·m,平均功率为1.114 kW;微耕机旋耕刀组平均转速为100 r/min时,平均转矩为238 N·m,平均功率为2.568 kW,与室内土槽试验获得的旋耕刀组的基础数据基本一致。测试平台运转顺畅,行驶平稳,耕深稳定。

The real working condition of the field test could not be fully stimulated in the soil bin.Based on the SR1Z–135multifunctional micro–cultivator,a field test platform with transmission system,measurement system,testing system andwalking system,was developed for tillage components of micro–cultivator.This platform could be used to test the workingperformance of rotary blade,deep tillage blade,anti–wrap blade and ridger in the field.The data of working performanceparameters such as speed,torque and power of tillage components could be processed,displayed and analyzed convenientlyduring the experiment.The field testing results showed that the average torque and power of rotary blades ofmicro–cultivator were226N·m and1.114kW at the rotating speed of47r/min,and those were238N·m and2.568kW atthe speed of100r/min,respectively.They were same as the experimental data of the rotary blades obtained in the soil bin.This platform was operating with smooth operation,steady driving and stable tillage depth in the working process.
