Description

Railway two-way loading chute

technical field

The invention belongs to a continuous loading device for bulk materials transported by railways.

Background technique

At present, most small and medium-sized enterprises use centralized single-point loading for railway transportation of bulk materials. The incoming materials from the belt conveyor are directly unloaded into the loading chute, and then loaded into the train carriage from the loading chute. This structure is simple, but there are The following problems: First, most of the loading chutes are italic single dustpans, or two-way dustpans. During the loading process, the sealing performance is not good, the dust is large, and the pollution is serious; When the loading is stopped, the conveying system should be stopped immediately, so that the conveying system will start with load when it is started next time, which will affect the service life of the equipment; the third is the gap between the two trucks where the single dustpan loading is dynamically moving forward during the loading process The loading must be stopped, otherwise the materials will fall on the railway, reducing the loading efficiency.
