Summary: | 针对"11SM-1.5型滚筒式残膜回收机"核心工作参数匹配不合理,机具在作业时,常常由于使用者操作方式与水平存在差异,影响残膜回收的总体拾膜性能,进而降低残膜拾净率。滚筒式残膜回收机是一种以弧线往复式挑膜装置为核心部件的典型残膜回收机具,该研究根据滚筒式残膜回收机的结构和工作原理,分析弧线往复式挑膜装置的挑膜齿尖运动轨迹特点,确定影响机具性能的主要因子为挑膜装置转速、机具前进速度和挑膜齿入土深度,采用正交试验分析法进行田间试验,分析不同参数配比对残膜拾净率的影响,得出各因素的影响显著性及主次顺序。综合考虑挑膜装置各项指标,选择最优的水平组合,获取机具的最佳工作参数匹配,即:挑膜装置转速45 r/min、机具工作速度4 km/h和挑膜齿入土深度35 mm时,残膜拾净率为88.2%,达到残膜回收机设计标准,比目前成熟的秸秆还田联合式残膜回收机的官方测定捡拾率高6.2个百分点,为机具优化设计提供数据参考,进而指导实际生产。 |

Bibliography: | 11-2047/S Plastic mulch technology is an important mean to promote agricultural production efficiency and increase income of farmers.As increase of using mulch plastic film in agriculture production,recover and recycling of the film become an issue.So there is an urgent need for an efficient and reliable technique of mechanical recovery of residual film to solve the problem of increasingly serious pollution of arable land caused by the debris of mulch film.1LSM-1.5 roller type residual film recycling machine is a typical waste plastic mulch film recycling machine,with arc reciprocating film picking drum as core device.This device has a problem of improper matching of working parameters.When the machine operated,because of the uneven of user's operation level,and the improper structure design of the machine,the overall performance of residual film recovery is affected resulting in reduction of recovery rate of residual film.Recovery rate of residual film is an important index of overall performance of roller ty |
