Scraper chain conveyor trough with reinforcing plate

摘要

A plate and scraper chain conveyor trough is disclosed for mining operations. Each conveyor trough which has opposite lateral sidewalls is provided with reinforcing plates which are welded to the sidewalls. Each reinforcing plate has a socket member at one end and a ball member at the other end. The ball member is adapted to engage a socket member of a plate in an adjacent trough to enable the conveyor length made up of a plurality of troughs to withstand increased pull from a scraper chain which is pulled with increased power.
