中文摘要:现有生物质压块机盖体开合机构多采用液压缸直接推动盖体的开启、闭合,存在开启角度小,影响喂料,液压缸尺寸较大,结构不紧凑等缺点。论文对生物质(秸秆)压块机盖体开合机构进行改进设计,采用液压缸驱动曲柄摇杆机构实现盖体的开启、闭合,利用机构死点提高盖体闭合时的稳定性,使盖体开合平稳,运动可靠。通过采用辅助圆法设计计算,分析了曲柄摇杆机构的运动,建立了机构模型。通过机构仿真,实现了机构预期的运动要求。

Abstract:Commonly in the biomass briquetting machine, hydraulic cylinder directly impulses the covering for lock and unlock in the covering mechanism for closing and unclosing. But the unlock angle was finite in this kind of scheme. The angle might impact material feeding, and hydraulic cylinder was too big, so the structure was incompactly. Against those shortcomings, a new mechanism was designed to actualize the function. The new scheme adopted crank and rocker mechanism for lock and unlock the covering. This mechanism was powered by hydraulic cylinder. The covering would be more stable when the dead point appeared. The crank and rocker mechanism was calculated with auxiliary circle, and the model for simulation was established. The requirement of mechanism motion can be realized by simulation.
