| 从振动技术原理出发,介绍了国内外振动技术在现代农业生产中的研究进展;从农作物播种、种子加工、果实收获、农业物料定向排序等方面,总结了振动技术的应用现状,重点阐述了农业物料在振动作用下的排序及定向原理。研究认为,由于农业物料种类繁多,外观特征复杂,形状不规则,质地不均匀,物理参数难于测定,给振动力学和数学模型的建立增加了难度,应加大对农业物料的优化设计和物料力学特性的基础性研究,建立振动力学和数学模型。总之,振动技术与农业生产的物料特性相互融合,可以实现作物播种、收获、种子定向排序、施肥、耕作等作业的机械化和自动化,为全面提升农业生产耕种收综合机械化水平提供新的技术支撑。 |

| Abstract: |
| This paper introduced the national and international research progress of vibration technology in modern agricultural production,and summarized the application of vibration technology in croping seeds,seed processing,fruit harvest,farming materials ordering etc.The discussions were mainly focused on the effect of vibration on agricultural material selection.Due to the wide variety of agricultural materials,and their complex appearance,irregular shape,uneven texture,it was difficult to determine physical parameters for vibration mechanics and mathematical modeling.So the suggestion that the paper gave was to increase the optimal design and basic research for mechanical properties of agricultural materials.In a word,the integration between the vibration technology and agricultural production material properties could achieve mechanization and automation of agricultural production of crop planting,harvesting,seed directional sorting,fertilizing and tillage operations,and provide a new technical support for enhancing the agricultural mechanization level. |
| Key words: vibration technology agricultural production vibrated seeding apparatus orienting and ordering of agricultural material automation |
