统收式采棉机载籽棉预处理装置的优化试验

为寻求统收式采棉机载籽棉预处理装置结构与工作参数的最优组合,对其进行了参数优化试验。采用正交试验以及Box-Behnken响应面试验方法,以行进速度、辊筒线速度、排杂间距为影响因素,以籽棉含杂率、清杂损失率为评价指标,对影响该机采收性能的结构与工作参数进行优化试验研究。结果表明：当行进速度为1.3 km/h,辊筒线速度为9.83 m/s,排杂间距为13.23 mm时,优化后籽棉含杂率5.56%,清杂损失率0.84%。棉花纤维检测显示,机采籽棉纤维各项指标等级与手采棉持平,满足生产需求,验证了该装置的合理性与实用性。该研究可为机载籽棉预处理装置的进一步发展提供理论依据,同时为统收式采棉机的推广与...

To determine the optimal parameter combination of the machine mounted seed cotton pretreatment apparatus of stripper cotton harvester, in 2014 and 2015, we conducted optimization experiments by using an orthogonal and a response surface experiments designed by Box-Behenken in Anyang, Henan. The current stripper cotton harvester takes in lots of large impurities like branches, which are unable to be cleaned out during harvesting. This becomes the most limitation for the machine, and is caused by its property of being easy to twist with seed cotton. In the past experiments, researchers found that most branches mixed with seed cotton reaching a length at 20 cm, which makes the problem harder to be resolved. Small impurities such as bolls and leaves, though take a smaller percentage, are not only difficult to be cleaned out once they entered pretreatment apparatus due to its brittleness, but also easy to be crushed down and twisted deeply with seed cotton which would directly influence the price of seed
