Title:
BELT TYPE CONVEYOR
Document Type and Number:
Japanese Patent JPS61254407
Kind Code:
A
Abstract:
An endless conveyor belt 7, with buckets or other digging or scraping elements secured to its outer surface at spaced locations, has at least one row of discrete blocks of resilient material bolted to the inner surface of the belt to form a continuous resilient material bolted to the inner surface of the belt to form a continuous resilient guide 7 member 11. As the endless belt passes around the end pulleys a wedging action is created as the discrete blocks, which have tapered side walls, press down into peripheral grooves 29 in the end pulleys which also have tapered, side walls but slightly narrower width than the members 11. The belt is preferably reinforced with embedded wire cables or fabric cords 9 so as to resist radial digging forces which tend to stretch the belt and pull it away from the end pulleys. Lateral forces generated as the digger is advanced into a pile of bulk material on a bias, which tend to cause the belt to creep laterally on the pulleys, are resisted by the restraint of the resilient guide members. Seals prevent bulk material from getting between the endless belt or its resilient guide members and the end pulleys, and scrapers remove any such material which gets past the seals and deflects it laterally out of the belt loop.
