Abstract

China annually produces over 210 million tons of rice straw; however, its utilization as feed remains low due to the scarcity of supporting equipment. In feed production, wrapping straw bales with plastic film is crucial for accelerating degradation. Given the diverse types of straw balers, a variety of wrapping machines are required. This study presents the design of an adjustable wrapping machine capable of handling straw bales with diameters ranging from 400 to 1200 mm and lengths between 500 - 1000 mm. Wrapping time, coefficient of variation, and elongation rate were selected as key evaluation indicators. Experimental results demonstrate that all performance metrics comply with industry standards for straw bale machinery, indicating the machine's practical feasibility and reliability in agricultural applications.

中国水稻秸秆年产量在2.1亿吨以上，但饲料化利用率仍然很低，其原因是缺少配套的装备，饲料化生产需要利用塑料膜包裹稻草捆以加速降解。由于秸秆打包机类型较多，故此需要不同型号的包膜机与之相匹配。本工作设计了一种可调包装机，可实现直径400~1200mm、长度500~1000mm的稻草捆进包膜处理。选取缠绕时间、变异系数和伸长率作为评价指标，通过包膜检验包膜效果。结果表明，各项指标均达到了秸秆包捆机械的行业标准。
