| 摘 要： | 要实现奶牛精细饲喂必须保证装备的给料精度，该文通过对传统给料装置进行研究，设计了基于等径变螺距的奶牛精确饲喂螺旋给料装置，并对不同螺旋主轴转速和投料时间对试验装置的投料稳定性影响进行了试验研究，确定了螺旋主轴转速并拟合出装置的投料模型。试验结果表明，给料装置在150 r/min转速下投料最稳定，投料精度高于95%，最大投料时间11 s，满足奶牛精细饲养给料精度的要求。

| Abstract: | In order to achieve the precision-feeding of dairy cow, the device accuracy must be assured. Based on the study of traditional feeding device, dairy cow precision feeding spiral device was designed using equal-diameter and variable-pitch methods in this study. The effect of different spiral spindle speeds and feeding times of testing device on the stability of precision feeding were studied through the experiment. Then, the spiral spindle speed was determined and the feeding model was designed. The experimental results showed that the 150 r/min was the most stable screw speed, feeding precision was above 95% and the maximum time of feeding was 11 s. The precision of feeding can meet the requirements of precision feeding of dairy cow. |
