| 摘 要： | 针对现有联合收获机割台搅龙向链耙输送器输送油葵时产生的回带和堵塞问题,对搅龙和链耙输送器关键部件进行优化,设计加工试验台架并进行了试验研究.单因素试验确定搅龙转速最优水平为170r·min-1、搅龙拨板倾角最优水平为12°,输送槽倾角和搅龙底板倾角最优水平为25°,刮板高度最优水平为50mm,输送间隙最优水平为25 mm.根据单因素试验结果搅龙转速、搅龙拨板倾角和输送槽倾角对输送效果影响较大,正交试验表明,影响输送效果的主次因素为输送槽倾角、搅龙转速、搅龙拨板倾角,最优参数组合为搅龙底板倾角和输送槽倾角均为25°,搅龙转速170r·min-1,搅龙拨板倾角12°;该条件下输送率为100％,籽粒脱落率不足0.6％,输送过程稳定可靠,不存在堵塞问题,完全满足油葵联合收获机的作业要求.

| Abstract: | The existing combine harvester header auger had problems such as reentry and clogging when it transported oil sunflower to the chain harrow conveyor. This article had optimized the key components of the auger and chain harrow conveyor, designed and processed the test bench and carried out experimental research. The single factor test determined that the optimal level of the stirring speed was 170 r·min-1, the optimal level of the auger digger dip angle was 12 °, the optimal level of the conveying groove angle and the angle of the agitation floor was 25 °, the optimal scraper height was 50 mm, and the optimal level of the conveyance gap was 25 mm. According to the single-factor test results, the stirring speed, the auger digger dip angle and the conveying groove angle greatly influence on the conveying effect. The orthogonal test showed that the primary and secondary factors that affected the conveying effect were the conveying groove angle, the stirring speed, and the auger digger dip angle. The optimal parameter combination was that the angle of the agitation floor and the conveying groove angle were both 25 °, the stirring speed was 170 r·min-1, and the auger digger dip angle was 12 °. Under the above conditions, the conveying rate was 100%, and the seed shedding rate was less than 0.6%. The conveying process was stable and reliable and fully met the requirements of the oil sunflower combine harvester. |
