谷物联合收获机脱粒技术与装置发展现状
Development Status of Threshing Technology and Equipment of Grain Combine Harvester
摘要
Abstract
As one of the core working parts of the grain combine harvester,the performance of the threshing device directly affects the quality of the machine.In order to solve the problem of low harvest quality caused by the large loss of grain combine harvester threshing device in China,the mechanical properties of grain,grain harvesting theory,parts of threshing device,structural parameters and motion parameters of threshing device,research on grain harvesting threshing technology,loss monitoring and control methods of threshing device were reviewed,aiming to improve the design of threshing device with higher performance.In the process of experimental research,the following steps needed to be carried out:detailed theoretical analysis and calculation of the existing device,including efficiency,power consumption etc and optimization of the design through calculation simulation.The advantages and disadvantages of different types of devices should be analyzed to select the appropriate combination of threshing devices and components according to the characteristics of crops,and design and conduct bench tests and small-scale field trials to verify the effectiveness of the improved design,combined with the internet of things,big data and artificial intelligence technology,develop intelligent threshing devices,real-time monitoring and automatic control,so as to achieve the goal of precision agriculture and bring higher benefits to agricultural production.关键词
