立辊型玉米收获机运动参数对损失率的影响

通过正交试验,研究了立辊型玉米收获机摘穗辊转速、夹持链速度和机器运动速度3个在玉米收获过程中的主要运动参数对损失率的影响,同时对各运动参数的交互作用进行了对比分析,确定出了最优生产条件,即各运动参数的最佳配合。试验表明,影响损失率的主要因素是摘辊转速;各运动参数的交互作用对籽粒损失影响不显著;各运动参数的最佳参数为:摘穗辊转速1000r/min、夹持链速度2.7m/min、机器运动速度1.67m/s。

Influence of working parameters on loss rate of vertical roll corn harvester

The influences of 3 major motion parameters in the working process of a vertical roll corn harvester, the speed of snappling roll, the speed of clamping chain and the driving speed of harvester, on the loss rate of the harvester were investigated by means of the orthogonal experiment design technique. The interactions of these motion parameters were analyzed to find the optimal production conditions, that is, the optimal combination of the motion parameters. The experiments have shown that the speed of snapping roll is the most significant factor on the loss rate, the influence of interactions of the motion parameters is insignificant, and the optimal motion parameters are: snapping roll speed 1000 r/min, clamping chain speed 2.7 m/min, and harvester driving speed 1.67 m/s.
