摘　　要：针对小麦收获机的扬尘治理,提出了采用静电除尘和喷淋除尘进行复合除尘的方法,分析了粉尘颗粒的运移规律、粉尘所处的电场和流场对粉尘运移的影响。结合SolidWorks三维绘图软件设计了机体改进部分的形状特征,分析了割台处的除尘效率,优化设计了喷淋除尘装置中水箱、泵体、喷头。通过理论分析,除尘效率能达到90%。该复合除尘装置的研制,为农业机械作业防尘装置的设计及其合理应用提供了一定的理论参考。This paper proposes a comprehensive use of electrostatic dust removal and spray dust removal for dust control of wheat harvester.It discusses the impact of migration law of dust particles,the electric field and flow field of dust on dust migration.Combined with SolidWorks 3D drawing software,the shape characteristics of the improved part of the body are drawn,the dust removal efficiency at the header is analyzed,the water tank,pump body and nozzle in the spray dust removal device are optimized.Through theoretical analysis,dust removal efficiency can reach 90%.This design proposes the idea of installing an electrostatic precipitator on a wheat combine harvester,hoping to lay the foundation for the dust removal device of the future grain harvesting machine.
