AI Technical Summary
In existing underground coal mine conveying systems, the friction between the coal on the conveyor belt and the baffles during the coal transport process causes squeezing and wear, affecting the quality of the coal.
The system employs a synchronous sealing mechanism and a cleaning mechanism. By limiting and moving synchronously on both sides of the first conveyor belt, friction between the coal and the baffle is avoided, while the cleaning mechanism removes any remaining coal.
It effectively avoids squeezing and wear during coal transportation, ensuring coal quality, and the cleaning mechanism improves transportation efficiency.
