一种移动式组合清理筛的设计
|
摘要
油料作物在机械化收获后,由于处理不当而导致的含杂率高和受污染等问题致使在仓储及加工过程中出现损失和清理困难的现象。为确保油料作物从收获到仓储过程不落地、含杂率满足国标要求,基于模块化集成设计理念,设计了一种集斗式提升机、高效清理筛、风机、旋风除尘器、风网管道和移动机架等于一体的新型移动式组合清理筛。利用动力学分析手段,对组合清理筛的薄弱支撑部位结构参数进行了优化,获得了该部位的钢板厚度合适尺寸。研究提高了油料产后清理筛分效率和仓储安全。
For the high impurity rate and pollution of oil crops after mechanized harvesting due to the improper handling,the phenomenon of loss and difficult cleanup during storage and processing is caused.In order to ensure that oil crops do not fall from the harvest to the storage process,and the impurity rate meets the requirements of the national standard,a new type of mobile combination cleaning screen with bucket elevator,high-efficiency vibrating screen,fan,cyclone dust collector,wind screen pipe,and movable frame was designed based on the modular integrated design concept.Using dynamic analysis methods,the structural parameters of the weak support site of the combination cleaning screen were optimized,and the appropriate size of the steel plate thickness at this site was obtained.The mobile combination cleaning screen improved the screening efficiency and storage safety of post-production cleanup of oil crops.
