TH1111A - Sweeping bridge for direct material feeding - Google Patents

Abstract

The invention of a sweeping bridge for sweeping materials from material piles on a conveyor belt using a chain-saw mounted on the bridge with The handler feeds the material from the material to the sweeper chain. The speed of the conveyor and that of the sweeper bridge, the chain and the handler is controlled. Controlled by using a belt scale at the exit end of the conveyor belt. Easy to control the speed of the conveyor belt and other parts. In order to release a fixed amount of material per unit time, the next measuring mechanism is mounted on the bridge to move Together in order to accurately measure the feeding level of the conveyor belt The successor to the position after the material is received from the chain and the measuring mechanism controls the relationship between the speed of the sweeping bridge. And of chain sweepers, transferers and conveyors To add The relative speed of the bridge when the belt feed rate Conveyor is lower than the preset value And reduce the relative speed of the sweeping bridge when the feed rate of the conveyor 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 installed 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 the 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 the To release material at a constant quantity per unit time, with the effect of on the bridge sweeping and the movement Together with the sweeping bridge There is also a measuring mechanism installed in order to measure the level. Continuous feeding of the conveyor belt 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 a 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).
