TH6137B - Sweeping bridge for direct material feeding - Google Patents

Abstract

The invention of a sweeping bridge for sweeping material from a pile on a conveyor belt using a sweeping chain mounted on a sweeping bridge with The conveyer which feeds the material from the material pile to the sweep chain. The speed of the conveyor and of the sweep bridge, the sweep chain and the unloader are regulated. It is controlled by a belt scale at the output end of the conveyor belt. speed control of conveyor belts and other parts of the sweep bridge in order to allow a fixed amount of material to be released per unit time. The next measuring mechanism is mounted on the sweeping bridge to move. together to measure the feed level of the conveyor belt like Consequently, the position after receiving the material from the sweep chain and the mechanism, in this measure controls the relationship between the speed of the sweep bridge. and of sweep chains, unloaders and conveyors. in order to add The relative speed of the bridge when the belt feed rate Conveyor lower than preset value and reduce the relative speed of the sweep bridge when the feed rate of the conveyor belt exceeds the preset value.

Claims (2)

1. The sweeping bridge for sweeping material from a long pile consists of a scraper that is used to move material down from the end of the pile by a It is mounted on a transfer body that can slide back and forth along the bridge. Sweep and perpendicular to the material core line in the base line of the pile. Front material The bridge swept along with the sweeper had been moved. Go into the material pile with the bridge drive and there is a chain sweeper parallel to the bridge for sweeping material with the scraper down the line. Connected conveyor In a direction parallel to the material pile By belt speed The conveyor was connected in relation to the drive unit, the sweeper bridge, the chain sweeper, and the transfer carrier. Weigh the belt at the exit end of the conveyor belt. Rate control Belt speed and other equipment Of the sweeping belt for To release material at a constant amount per unit time, with the effect of on the bridge sweeping and the movement Together with the sweeping bridge Also has a measuring mechanism installed in order to measure the level Continuous feeding of conveyor belts next to the point Get the material from the sweeping chain And the signal from the measuring mechanism will act That governs the relationship between the speed of the sweeping bridge and The sweeping chain, as well as the transfer and conveyor to ensure the The relative speed of the sweeping bridge increases as the feed rate Of the conveyor falling below the set value and decreasing When the feed rate is higher than the rated value 2. The bridge swept according to claim 1 has a special feature that The measuring mechanism is a belt scale (2 claims, 1 page, 1 figure).
