在对9ZF-1.0型盘刀式切碎器切碎玉米秸秆(水分含量50％)的试验基础上,本文分析了其功率消耗的组成;求出了各部分功率消耗在不同转速情况下所占的比例;并统计出了各部分功率消耗的回归方程。试验结果表明:切碎器各部分所消耗的功率随着切碎器的转速变化而改变;在以比消耗能为评价指标的前提下,切碎器的转速不宜过高或过低,而应使比消耗能最低为目标,从而使切碎器工作时的经济效益达到最佳。试验分析结果,9ZF-1.0型切碎器在切割玉米秸秆(水分含量50％)时的最佳转速范围为560-640r/min。
Based on the experiment of chopping corn stalk (moisture content 50%) by 9ZF-1.0 disc cutter, the composition of power consumption was analyzed and the power consumption of each part was calculated under different speed Of the ratio; and statistics of the various parts of the power consumption regression equation. The test results show that: the power consumed by each part of the chopper changes with the speed of the chopper; under the premise of the specific energy consumption as the evaluation index, the speed of the chopper should not be too high or too low, So that the lowest energy consumption as the goal, so that the work of the chopper to achieve the best economic benefits. Test results show that 9ZF-1.0 type chopper in the cutting of corn stover (moisture content 50%) when the optimum speed range of 560-640r / min.
