为验证所设计的油茶果粗选机的合理性,该文首先对其进行简化,联系振动筛工作原理和受力分析对其运动参数进行分析,找出影响物料运动的因素,并验证其运动参数设计合理;其次利用ADAMS仿真软件对该机进行运动仿真,得到物料模型的振幅曲线图,通过使用振幅递减法分析曲线图的变化规律,验证其振幅设计合理;最后通过三水平三因素正交组合试验,得出各因素对茶籽保有率和筛分效率的影响显著性顺序。利用Design-Expert软件分析得出当粗选机曲柄转速、筛面倾角、筛面长度取值为276.12 r/min、6.69°、1 005.8 mm时,茶籽保有率和筛分效率均达最佳值(分别为96.84%和96.77%),验证了粗选机的设计满足工作要求。...

Nowadays because the separation step of shell and seed of oil-tea fruit wants to reach the ideal effect by one pace, they can not get satisfactory separation rate of shell and seed. In our study, we determine to choose roughing at first, and then select cleaning method. In order to improve the efficiency of the late selection and separation, design an oil-tea fruit coarse sorting machine which is simple in structure and convenient in manipulation and easy to latter careful sorting. Its work is to shell big shells, break tea fruit, without break...
