针对南方农艺要求、土膜分离难等问题,设计了一台南方残膜回收机。结合机器工作原理,对影响土膜分离性能的扎膜部件举升角度、机器行走速度以及残膜延展率3个因素进行单因素试验和多因素正交试验。结果表明:扎膜部件举升角度对残膜回收机的土膜分离性能有着显著的影响,且当扎膜部件举升角度为35°,机器行走速度为5 km/h,残膜延展率选定为30%时,残膜回收率高于95%,夹带土壤质量低于0.50 kg/m^2。此机器符合南方作业条件,克服了土膜分离难的问题,满足残膜回收要求。

We designed a plastic film residue recovery machine aiming at soil film separation and the agronomic requirements in southern China.Considering the working principle of the machine,we carried out the single factor test and multi-factor orthogonal test on three factors which affected the performance of soil film separation,i.e.the lifting angle of the pricking components,the moving speed of the machine and the elongation of used film.The results showed that:the lifting angle of the pricking components had a significant effect on the soil film se...
