摘要
该文介绍了作者设计并研制的双轴卧式全混合日粮混合机，阐述了主要结构及工作原理。为了优化其结构与运动参数，采用二次回归正交旋转组合试验设计对5个试验因素进行了混合均匀度及物料细粉率作为指标的试验研究，得出了其结构与运动参数的合理组合，即揉搓转子转速宜取40-50r／min、剪切转子转速宜取55-65r／min，转子间隙宜取11～13mm，齿杆角度宜取5°～10°，混合时间宜小于10min，充满系数不应小于0．1。在全混合日粮混合试验中，混合均匀度指标以变异系数进行评价，并以食盐为示踪物进行了变异系数分析，试验结果证明该法准确、简单、可行。
The main structure and working principle of the twin-shaft horizontal total mixed ration mixer were discussed in the paper. For optimization parameters in structure and motion, the experimental method for the five-factor quadratics rotary orthogonal combination was adopted, and two evaluation indexes （mixing homogeneity and material powder） were applied in the experiment. By the experiment, the reasonable parameters in structure and motion were obtained, that is, rotational speed 40-50 r/min for rubbing rotor, 55-65 r/min for cutting rotor, clearance 11-13 mm, rod angle 5°-10°, mixing duration less than 10 min, loading coefficient more than 0. 1. In the experiment, the coefficients of variation were analyzed by determination of salt content, experimental results testify that this method is accurate, simple, practical.
