加工番茄回转滚筒式果秧分离机构参数正交试验优化

为了优化加工番茄果秧分离机构的技术参数,设计并制作了回转滚筒式分离试验台。以里格尔87-5加工番茄为试验对象,应用二次回归通用旋转组合试验方法,建立了果秧分离性能指标与滚筒转速、凸轮盘转速和拨杆振幅之间的回归方程。分析了试验因素对分离性能的影响规律,在果秧分离率、果实破损率和含杂率满足作业质量的条件下,优化得出滚筒转速为21 r/min、凸轮盘转速为42 r/min和拨杆振幅为110 mm。

Orthogonal Experiment Optimization of Parameters of Rotary Roller-type Fruit-vine Separation Mechanism for Processing Tomato

In order to optimize the operation parameters of the processing tomato fruit-vine separation mechanism,a rotary roller-type separation bedstand was designed.Mathematical models that described relationship between the performance indexes and influence factors of the separation mechanism were established by applying quadrate regression experiment with general rotary design method.The tendency and regularity of the separation performance influenced by the factors were analyzed.For the Ligeer 87-5 processing tomato,with a certain tomato separation rate,tomato damage rate and tomato impurity rate,the roller rotation speed was 21 r/min,cam plate rotation speed was 42 r/min,deflector rod oscillation amplitude was 110 mm by parameter optimization.
