摘要
针对我国中大型饲草打捆缠膜装备缺乏、中小型打捆缠膜机作业质量不高的现状,研究旨在设计一种打捆直径900 mm的电动式饲草打捆缠膜机,并确定其最佳工作参数.采用理论设计与试验分析的方法确定整机结构方案,分别对打捆装置、喂入装置、送网装置、配料装置、缠膜座及缠膜装置等进行结构设计与参数分析.试验通过双因素试验分析,确定了作业噪声、单捆能耗、打捆密度与开舱电流、打捆电机频率之间的回归方程,通过性能指标目标函数求解确定最优作业参数,即开舱电流22.63 A、打捆电机频率49.66 Hz.在最优作业参数下,作业噪声为86.56 dB(A),单捆能耗为0.37 kWh,打捆密度为758.13 kg/m3,此时整体作业性能最佳,可满足饲草打捆缠膜青贮作业需求.
Abstract
In view of the lack of medium and large forage baling and wrapping equipment in China and the low operation quality of small and medium-sized baling and wrapping machines,the purpose of this study was to design an electric forage baling and wrapping machine with a baling diameter of 900 mm,and determine its optimal working parameters.By using the method of theoretical design and experimental analysis,the structure scheme of the whole machine was determined,and the structural design and parameter analysis of the baling device,feeding device,net feeding device,batching device,wrapping seat and wrapping device were carried out respectively.Through two-factor test analysis,the regression equation between baling noise,single bundle energy consumption,baling density,cabin opening current and baling motor frequency was determined,and the optimal operating parameters were determined by solving the objective function of performance indicators,namely the cabin opening current of 22.63 A and the baling motor frequency of 49.66 Hz.Under the best operating parameters,the baling noise was 86.56 dB(A),the energy consumption of a single bundle was 0.37 kWh,and the baling density was 758.13 kg/m3,and the overall operation performance is the best,which meets the needs of forage baling and wrapping silage operations.
