【摘要】 鉴于目前草物料在季节上和地区间的供需矛盾以及新鲜草物料在调制干草产品过程中营养损失严重的问题，进行了新鲜草物料压缩试验研究。本文以9KG-350型液压高密度压捆机为试验装置，利用测试技术，对典型新鲜苜蓿草、苏丹草和玉米秸秆进行了直接压缩过程的测试研究。根据试验数据建立了压缩力与压缩位移和压缩力与压缩密度的数学模型，并对三种草物料在不同喂入量下的压缩过程进行了理论分析研究，得出了喂入量对压缩过程基本参数的影响规律。在此基础上，综合分析喂入量与最大压缩力、最大压缩密度、压缩设备的生产率和压缩功耗之间的关系，给出了较合理的喂入量，为压缩设备的优化设计提供理论依据。更多还原

【Abstract】 In view of the contradiction existing between supply and demand arisen from seasons and regions and the problem of serious nutrition loss in the production process of making fresh herbage material into hay product, an experimental study of the compression process was conducted for the typical fresh herbage materials such as alfalfa, Sudanese sorghum and corn stalk on the 9KG-350 model high density baler. Based on the data of experiment, a mathematical model in term of the relationship between compression pressure and displacement as well as the compression pressure and density was established and a theoretical analysis was carried out for the compression process of the said three kind of herbages at different feeding rate, having acquired the law for the feeding rate to exert influence on the basic parameters in the compression process. On the basis of the above, a comprehensive analysis on the relationship between the feeding rate and the maximum compression pressure, maximum compressed density, productivity of baler and the power consumption were conducted respectively, having determined more reasonable selection of feeding rate and also advanced a theoretical basis for the optimum design of the baler.更多还原
