【摘要】 切碎滚筒是青贮饲料收获机的重要工作部件,直接影响收获机的功率消耗、切碎性能及抛送性能。本研究在试验的基础上,设计了新型平板刀式滚筒切碎器,分析了滚筒切碎器的结构参数和运动参数对切碎性能的影响,确定了平板刀刃口曲线方程和较优的工作参数。试验研究证明:滚筒转速和喂入量是影响功耗的重要因素。饲草的切碎均匀度与滚筒转速呈正相关。更多还原

【Abstract】 Shredding drum is a major operating unit on the cylinder-type forage harvester. It influences the mincing performance, expulsion performance and power consumption of machine directly. Therefore, the new plane table-knife drum cutter was designed on the basis of experiments, the effects of structure parameters and mobile parameters of cutter on the working performance have been analyzed. Parameters of working condition and curve equation of cutting edge was ascertained. Experimental results show that power consumption of machine was ascended by increased rotating speed and feed quantity. Quicker the rotating speed of cutter drum, the better cutter quality and higher expulsion performance.更多还原
