马铃薯挖掘与残膜回收一体机的改进设计与试验
Improved design and experiment of combined operation machine for both potato harvesting and plastic film collecting
摘要
Abstract
Aiming at the existing problems such as the hug membrane device bruising on potato tuber epidermis easily,the low recovery rate of residual film and the phenomenon of tearing plastic film,a field test of combined operation machine for potato harvesting and plastic film collecting was conducted and the recovering part of residual film was improved.Based on the 4U-83 potato harvester,its film feeding device and roller type film rolling device were used for recovering part of residual film.The key parameters of all devices were calculated and determined,and the location of the film pressing wheel was determined,as well as the film feeding device and film rolling device.The results showed that:This machine could smoothly dig and transport potato,and effectively separate soil and potato.The plastic film can be rolled up continuously by the roll film tube and reliably unloaded in convenient.The potato distinct rate reached 97.2 ％,the damage rate was 3.7 ％,the loss rate was 4.2 ％,and the recovery rate of the residual film was 90.1％.In conclusion,the improved operation machine reached the relative technical requirements for the potato machinery harvest and the recovery of the plastic film.关键词
