Abstract
The pans of a scraper-chain conveyor are interconnected by way of a dog-bone type connector with enlarged end regions and a central shank which fits into shaped compartments in the side walls of adjacent pans. A hook-like projection on one of the end regions engages in a recess adjoining one of the pockets and a complementary web-like projection on the other end region lies in an opening adjoining the other of the pockets. A swivelling locking plate is fitted to the side wall to overlap the web-like projection and retain the connector in place.
Claims18
Means for connecting together two adjacent channel sections of a scraper-chain conveyor, the channel sections each comprising a pair of side walls and a floor plate connected therebetween;
- the connection means at least including a coupling member having a central shank and enlarged heads at opposite ends of the shank, laterally-open compartments provided in end regions of side walls of the adjacent channel sections and shaped to receive the coupling member, a projection provided on at least one of the heads, an opening defined between wall portions adjoining one of the compartments, a locking plate, means in the wall portions for locating the locking plate for swivelling to overlap the projection and to free the projection and a detachable locking element for securing the locking plate in the position overlapping the projection to retain the coupling member in the compartments.
