Research and Application of Intelligent Scraper Conveyor in Fully Mechanized Mining Face with Large Dip Angle
The intelligent scraper of the coal mining face in the three soft coal seams with a large dip angle includes the tail of the conveyor,the base,and the tail frame.The tail frame is installed at the upper end of the base and is fixedly connected to the base through welding.At the same time,a tail cover is installed on the tail frame of the scraper conveyor to ensure that the tail cover can protect the upper end and front end of the left half of the scraper tail frame.The tail cover consists of three parts:a lower cover plate,an upper cover plate,and a fixed cover plate.The upper and lower cover plates of the tail cover plate,as well as the upper cover plate and the fixed cover plate,are connected to each other through hinges.The tail cover plate can be opened when coal is discharged from the front and closed easily when the machine is stopped.The tail guard is easy to operate,safe and reliable,and can prevent coal slag from pouring onto construction personnel due to the lack of blocking devices when coal is discharged from the front end of the tail frame.This improves the overall performance of the scraper conveyor,reduces the labor intensity of operators,effectively ensures the safety of construction personnel,and also saves manpower and improves work efficiency.
