Research on Automatic Shoveling Control of Underground Scraper Based on Intelligent Drag-Reduction Strategy
In the process of shoveling operation,the bucket mechanical properties of the underground scraper are complex and changeable.The cab operator can only operate after real-time observation and judgment based on work experience,and the actual effect is not ideal.By studying the mechanical properties of the shoveling process,an automatic shoveling control method of the underground scraper based on the intelligent drag-reduction strategy was proposed,which could complete the automatic control of the shoveling process with high efficiency and low consumption.Based on the timing feedback,combined with the lifting bucket or prying bucket several times during shoveling process,the dense core in the material pile was destroyed continuously and the shoveling resistance was reduced to improve the full bucket rate and the working efficiency of the scraper.At the same time,based on the EDEM software,the intelligent drag-reduction shoveling process simulation research was carried out,and the automatic shoveling control system was built on the project scraper.Through human-computer interaction programming control,the engineering application was carried out.The results show that the automatic shoveling control system of underground scraper based on intelligent drag-reduction strategy has stable control effect and high reliability,which can fully meet the requirements of industrial application.
