摘要： A machine frame for a scraper-chain conveyor employs a housing or `plough box` containing a chain wheel for driving a haulage chain. A stripper device is provided in the housing to separate the chain from the chain wheel. The stripper device is composed of a one-piece shaped element with an arcuate blade projecting into the chain wheel. The element is fitted to a mounting flange of the housing with a single upstanding bolt-and-nut and a separate complementary locking member. The element, the locking member and the flange have shape-locking interengaging projections and recesses. The device can be positionally inverted.
