    摘要:

    针对叶菜定植盘残留基质、叶菜碎屑的问题,设计了一款工厂化叶菜定植盘清洗装置。该装置主要由机架、清洗组件、刮渣组件、防水组件等构成。工作时,定植盘由输送线送入清洗装置中,刮渣组件去除定植盘上较大块残留物,清洗组件去除基质、叶菜碎屑等。选用6530型不锈钢扇形喷嘴,以靶距和冲击角为试验因素,清洗面积占比为评价指标,进行单因子试验和二元二次回归正交组合试验。优化后的清洗参数为:扇形喷嘴出口孔径3.5 mm、水射流锥角65°、水射流靶距45 mm、水射流冲击角5°,清洗面积占比最大可达97.45%。经清洗试验验证,清洗面积占比均值为94.70%,可满足工厂化叶菜定植盘的清洗要求。

    Abstract:

    Base on the problem of residual matrix, leafy vegetable clastic and other dirt, a cleaning device of the planting tray was designed for industrialized leafy vegetable. The device is mainly composed of the frame, the cleaning component, the scraping component, the waterproof component and other components. The planting tray was sent horizontally into the cleaning device by the conveyor line during working process, and then the large residues on the planting tray were removed by the scraping component. The particles such as matrix, leaf vegetable clastic and sticky filth were removed by the cleaning component. The 6530 fan-shaped nozzle which made of stainless steel was selected. The single factor tests and binary quadratic regression orthogonal combination test were conducted by taking the target distance and impact angle as the test factors, and the proportion of cleaning area as the index. The optimal parameters combination were obtained that the outlet aperture of fan-shaped nozzle was 3.5 mm, the cone angle of water jet was 65°, the target distance of water jet was 45 mm, the impact angle of water jet was 5°, and the maximum cleaning area ratio was 97.45%. The average value of cleaning area ratio was verified to be 94.7% by the cleaning test of cleaning device for leafy vegetable planting tray, which met the cleaning requirements of industrialized leafy vegetable planting tray.
