Abstract
The pans of a scraper-chain conveyor are interconnected with a dog-bone type connector which fits into laterally open shaped pockets in the side walls of the pans. A projection on one of the ends of the connector engages in a recess closed off from the side access while a projection at the opposite end of the connector is locked in place with a swivelled-in locking plate. The plate fits into compartments in the side wall of the associated pan. The plate carries a resilient pin at one end which fits into recesses in one of the compartments while the opposite end of the plate has a tongue which snaps into a recess in the base of the opposite compartment.
Claims17
In connection 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 therebetween, the connection means comprising a connector with a central shank and enlarged heads at opposite ends of the shank, laterally-open pockets in end regions of the side walls of the adjacent channel sections shaped to receive the connector, a projection provided on at least one of the heads extending outwardly from said head relative to the shank and releasable locking means for engaging over the projection to secure the connector in position;
- wherein the locking means includes a separate releasable plate located to project over the projection and a resiliently deformable securing member carried by the plate and extending outwardly from at least one side of the plate, means defining a compartment in the side wall of one of the channel sections for receiving and end portion of the plate and means defining at least one recess for receiving the securing member.
In connection 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 therebetween, the connection means comprising a connector with a central shank and enlarged heads at opposite ends of the shank, laterally-open pockets in end regions of the side walls of the adjacent channel sections shaped to receive the connector, a projection provided on at least one of the heads and releasable locking means for engaging over the projection to secure the connector in position;
- wherein the locking means includes a plate with a resiliently deformable securing member extending outwardly from at least one side of the plate, means defining compartments in the side wall of one of the channel sections for receiving respective end portions of the plate and at least one recess adjoining one of the components for receiving the securing member wherein one of the compartments has a guide surface for guiding an associated one end of the plate into the one compartment as the plate is swivelled.
In connection 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 therebetween, the connection means comprising a connector with a central shank and enlarged heads at opposite ends of the shank, laterally-open pockets in end regions of the side walls of the adjacent channel sections shaped to receive the connector, a projection provided on at least one of the heads and releasable locking means for engaging over the projection to secure the connector in position;
- wherein the locking means includes a plate with a resiliently deformable securing member extending outwardly from at least one side of the plate, means defining compartments in the side wall of one of the channel sections for receiving respective end portions of the plate and at least one recess adjoining one of the components for receiving the securing member wherein one end of the plate has an outwardly projecting tongue and the compartment associated with said one end has a stepped recess for receiving the tongue at the one end of the plate.
In connection 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 therebetween, the connection means comprising a connector with a central shank and enlarged heads at opposite ends of the shank, laterally-open pockets in end regions of the side walls of the adjacent channel sections shaped to receive the connector, a projection provided on at least one of the heads and releasable locking means for engaging over the projection to secure the connector in position;
- wherein the locking means includes a plate with a resiliently deformable securing member extending outwardly from both sides of the plate, means defining compartments in the side wall of one of the channel sections for receiving respective end portions of the plate and recesses in the defining means for receiving both projections of the securing member.
