| 摘 要： | 为简化微型小麦联合收割机旋风分离清选系统的结构,便于推广应用,进一步满足微型小麦联合收割机清选性能要求,该文运用正交试验、通用旋转组合试验和优化设计,找到了分离筒内无导向片的旋风分离清选系统各部分的结构参数和运动参数的最优组合.试验结果表明,吸杂风机转速、扬谷器转速和分离筒上锥角对籽粒清洁率和清选损失率影响均显著,但简体高度对籽粒清洁率和清选损失率影响不显著.当吸杂风机的转速为2399 r/min,扬谷器的转速为1097 r/min,所得到的清洁率可达到99.15%,损失率为0.295%.

| Abstract: | To improve the cleaning performance of micro-combine harvester of wheat, facilitate applying of production, and meet requirements of cleaning performance of the micro-combine wheat harvesters, the optimum combination between structural parameters and motion parameters on cyclone separating system of no-oriented films are tested and verified based on orthogonal test and general rotary unitized test. The experimental results are analyzed by variance analysis method and regression analysis method. The results show that the rotate speed of catching impurity fan, the rotate speed of winnower, and the top cone angle have more evident effects on the cleaning rate and the loss rate of seeds than the height of separating barrel. The results can provide design reference for cleaning system of micro-combine harvester of wheat. When the rotate speed of catching impurity fan is 2399 r/min and the rotate speed of winnower is 1097 r/min, the cleaning rate is 99.15 percent and the loss rate is 0.295 percent. |
