摘要
文章针对我国玉米大垄双行整地技术落后和作业后垄型质量差等实际问题,研究全新的集土技术。对集土部件进行合理化设计,并依据试验设计方案,在探究作业速度、刀轴转速、集土深度和集土角度方面,对土壤碎土率和平整度的影响规律下,采用多目标优化的方法,进行模型优化,得到各因素的最佳组合,以满足响应指标。即作业速度3.85 km/h,集土刀轴转速179 r/min、集土深度21 cm和集土角度66°,此时土壤碎土率平均值为92.53%,平整度的平均值为3.5 mm。通过田间试验证明,该部件能够保证机具作业后的垄形更加标准,满足播种要求。
Aiming at the problems of backward technology and poor quality of ridge type in China,this paper studies new soil collection technology.Based on the experimental design scheme,the model is optimized by using the multi-objective optimization method to obtain the best combination of various factors to meet the response index.That is to say,the operation speed is 3.85 km/h,the rotation speed of the soil cutter shaft is 179 R/min,the depth of soil collection is 21cm and the angle of soil collection is 66°.At this time,the average value of soil fragmentation rate is 92.53%,and the average value of flatness is 3.5mm.Through the field test,it is proved that this component can ensure the ridge shape of the machine is more standard and meet the requirements of sowing.
