ABSTRACT
The plow system is composed of the plow head, plow chain, transmission, electric control system, hydraulic system and so on. The plough usually adopts the two-terminal motor drive. The work principle of the plough is that the plow head with the plane iron moves along the guide of the middle trough on the scraper conveyor under the traction of the plow chain, and the coal is loaded into the conveyor under the action of the pyriform incline of the plow head when the plane iron cuts the coal wall.
