BIN TRESTLE TO LOAD RAILWAY CARS AND METHOD TO RELOAD DUST-CONTAINING LOOSE MATERIALS FROM BIN TRESTLE INTO RAILWAY CAR Russian patent published in 2011 - IPC B65G67/00 B65G69/18 

FIELD: packing industry.

SUBSTANCE: bin trestle to load railway cars includes a metal structure installed above a rail track with feed bins (3), at least one of which (4) is designed to collect a dust-containing fraction. Feed bins are combined into two process lines with two scraper containers (7, 8) that includes inclined or bent sections (6), and vibration feeders. The unloading end of each scraper conveyor is equipped with a sliding dust-tight loading head (12) and is connected with it by means of a flexible transporting hose (13). Vibration feeders arranged under the loading nozzles of a bin for collection of a dust-like fraction are connected to loading nozzles of both scraper conveyors. The method of reloading includes movement of materials within the bins to the exit under gravity. Single flows are exposed to a volume vibration dosing at the exit from each bin and are combined into two separate flows, every of which is forcedly supplied to levels of receiving sections of sliding dust-tight loading heads.

EFFECT: invention reduces dust release.
