Abstract: A train bulk cargo loading system having a disconnected railroad track scale, includes a disconnected railroad track scale (1), a tractor (2), a lifting scraping plow (4), a controllable vibration charging hopper (6), a surge bin (8), a belt conveyor (9) and a control terminal (7). The train bulk cargo loading system having the disconnected railroad track scale has a low overall height and a small footprint, thus reducing the construction and production costs. The system integrates loading, trimming, measuring and data sharing, and features uniform loading, balanced train wheel pressure, and accurate measuring. Thus, huge human and material resources consumption caused by uneven loading of an original loading system, large wheel pressure deviation and secondary trimming and measuring required by the railway department may be avoided, significantly reducing the construction cost and operation cost.
