弹齿链耙式播前残膜回收机的设计研究

摘要

With the popularization and application of mulching technology ,white pollution caused by plastic film is getting worse .In order to reduce pollution , does not affect seeding , emergence , design a new type of spring-tooth-chain-rake incomplete plastic film recycling machine before planting machine .It highlights the aircraft's overall structure , working principle, key components such as pick-up chain harrow , spring-tooth, taking off the membrane mechanism for design analysis.Field test showed that the aircraft pure-hour production rate is 0.85hm2/h,recovery of plastic film is 81%.The plastic film recycling can meet the technical requirements and the study results may help solve the problem of plastic film pollution .%随着地膜覆盖技术的推广应用,残膜带来的白色污染越来越严重. 为了减轻污染,不影响播种、出苗,研究设计了新型弹齿链耙式播前残膜回收机. 重点介绍了该机的总体结构、工作原理,以及捡拾链耙、弹齿、脱膜机构等关键部件的设计分析. 田间试验表明:该机生产率为0.85hm2/h,残膜回收率为81%,满足残膜回收的技术要求,研究成果有利于解决残膜污染问题.
