Description

Shipment mechanism for cantilever type coal mine heading machine Technical Field The invention belongs to the technical field of coal mining equipment, and particularly relates to a shipment mechanism for a cantilever type coal mine heading machine. Background When the cantilever type coal mine heading machine works, coal is crushed through the cutting part to be separated from ore vein, then the coal is shoveled up through the shovel plate, the scraper on the shovel plate scrapes the coal onto the conveying belt in the middle of the shovel plate, the conveying belt penetrates through the machine body, and the coal is transported into a transport vehicle or other transport equipment behind the machine body.
