牧草高密度压捆时的变形恢复

Recovery of Compressed Hay Baled in High Density

通过试验和分析，研究了在不同喂入量和不同压缩维持时间的条件下，高密度压捆时牧草变形恢复的影响因素。结果表明，喂入量、压缩维持时间、牧草在压缩至内的位置和变形恢复时间等参数对压缩后牧草的变形恢复均有影响。回归选优分析结果为高密度捆单机的改进设计和有效使用提供了依据。

The recovering regularity of the compressed hay during high density baling with different feeding rates and compressive time is studied. It is affected by 4 factors: feeding rates, compressive time, the place of hay in baling chamber and recovering time. The test results are regressed and some recovering regularities of hay compressed are obtained. It is found that these factors are the essentials in the design and application of balers.
