| 中文摘要: |
| 针对目前大豆等油料作物产后由于缺少相关清理设备与收获机的有机结合，导致的粮食产后加工、储藏环节无法实现全程不落地，进而产生油料作物收获后含杂率偏高、杂质多样不能满足储藏和加工要求，使得生产和仓储企业需要二次清理，造成大量不必要的人力和物力浪费的突出问题，基于集成与模块化设计理念，设计了一种新型移动式组合圆筒清理筛。将移动式组合圆筒清理筛与油料作物专用收获机有机结合，确保油料作物收获后直接得到清理，使其含杂率满足储藏和加工要求。设备主要包括：斗式提升机、圆筒清理筛、风机、旋风除尘器和移动机架。另外，为提高清理设备整体结构稳定性和抗疲劳特性，采用动力学模态分析手段对设备进行了分析与优化，最后获得了设备关键部位及危险部位的最优结构参数。为设备的进一步推广提供了理论与技术支撑。 |

| Due to the lack of organic combination of related cleaning equipment and harvesters after the harvest of oil crops such as soybeans, the post-harvest processing and storage links cannot be achieved without landing. As a result, oil crops have high impurity content after harvest and do not meet storage and processing requirements, making production and warehousing companies need to clean up again, resulting in a lot of unnecessary manpower and material waste outstanding issues. Based on the concept of integration and modular design, a novel mobile combined cylinder cleaning screen was designed. It was organically combined with oil crop special harvesters to ensure the oil crops be cleaned directly after harvest and the impurity content meet storage and processing requirements. The equipment mainly included bucket elevator, cylinder cleaning screen, fan, cyclone dust collector and movable frame. In addition, in order to improve the overall structural stability and anti-fatigue properties of the cleaning equipment, dynamic modal analysis was used to analyze and optimize the equipment. Finally, the optimal structural parameters of the critical and dangerous parts of the equipment were obtained, which provided theoretical and technical support for the further promotion of the equipment. |
