摘要: 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三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,地膜回收率高于95%,夹带土壤质量低于0.50 kg/m。此机器符合南方作业条件,克服膜土分离难,满足残膜回收要求。

Abstract: We designed a southern plastic film recovery machine aiming at the difficulty of separation of soil and film and meeting the agronomic requirements in southern area. Considering the working principle of the machine, we carried out the single factor test and multi-factor orthogonal test for three factors which affect the performance of film and soil separation, i.e. the lifting angle of pricking components, the moving speed of the machine and the elongation of used film. The results show that the lifting angle of the pricking components has a significant effect on the soil film separation performance of the used film recovery machine. When the lifting angle of the film pricking parts is 35 degrees, the moving speed of the machine is 5 km/h, and the elongation of used film is set to 30%, plastic film recovery rate is above 95% and the entrained soil quality is below 0.50 kg/m. This machine conforms to the operation conditions in southern area, overcomes the difficulty of separating used film from soil, and meets the requirements of residual film recovery.
