大豆秸秆纤维制取机配套原料捞取装置设计与参数优化

Design and Parameters Optimization of Raw Material Dredging Device for Soybean Straw Fiber Extrusion Machine

为了提高大豆秸秆资源利用率,利用CATIA软件设计了秸秆纤维制取机配套原料捞取装置,采用二次通用旋转组合试验方法,以捞取量为响应函数,以捞取装置的耙头角度和耙齿角度为影响因素,对大豆秸秆原料捞取装置参数进行了优化试验研究。结果表明:在转速为55 r·min-1的条件下,当耙齿角度21.54°、耙头角度88.58°时,每次最大捞取量为0.39 kg,作业效果最佳。

In order to improve soybean straw resource utilization,the raw material dredging device for soybean straw was designed with CATIA software. The quadratic general rotary unitized design was carried out with rake teeth angle and rake head angle as influence factors,and dredging amount as experimental index. The results showed that the spindle speed 55 r·min^- 1,rake teeth angle of 21. 54°and rake head angle of 88. 58°were the best combination factors,which leaded to the most dredge amount of 0. 39 kg in each time. It can provide the basis for the design of rake.
