Unmanned Coal Cleaning Equipment

The unmanned coal cleaning equipment is an automatic residual coal cleaning machine specially supporting wagon tippler unloading systems. It clears residual coal left inside railway open wagons after tipping and discharging. Traditional manual residual coal cleaning works in dusty and narrow spaces with high safety hazards. Manual cleaning also takes much time, slows down wagon tippler circulation and restricts the capacity of the whole coal unloading line. The unmanned coal cleaning equipment can replace manual cleaning completely and finish wagon residual coal cleaning automatically.

This unmanned coal cleaning equipment adopts reciprocating travelling mechanism and composite wear-resistant sweeping assemblies. It is structurally optimized for high-humidity and sticky coal working conditions. After the wagon tippler finishes discharging and resets, the unmanned coal cleaning equipment starts cleaning automatically. The sweeping assembly stretches into the wagon and cleans caking and wet sticky residual coal repeatedly on the wagon floor. It takes ≤160 seconds for one full cleaning cycle per wagon, and the residual coal cleaning rate reaches ≥95%. After cleaning, the machine resets automatically and waits for the next working instruction.

The unmanned coal cleaning equipment applies PLC control system. Three working modes are available: automatic mode, local manual mode and maintenance mode. The control system achieves safety interlock with the main wagon tippler system. The unmanned coal cleaning equipment can only start cleaning after the wagon is in position and locked, preventing collision damage caused by misoperation. The system supports overload detection, fault alarm and operation data recording. Operators can remotely check real-time running status of the unmanned coal cleaning equipment and locate faults quickly to reduce maintenance difficulty.

The main frame of the unmanned coal cleaning equipment is made of Q235 carbon steel. Wear-resistant overlay is welded on contact parts for longer service life. With IP54 protection grade, the machine runs stably under heavy dust and wide temperature fluctuation in open coal yards. Modular assembly design enables separate disassembly of each functional unit. Daily maintenance and replacement of wearing parts are convenient without disassembling the whole machine, saving maintenance time and costs.

The unmanned coal cleaning equipment adapts to standard railway coal open wagons. The cleaning width and height can be adjusted according to actual wagon dimensions. The complete supply scope covers main sweeping unit, electric control cabinet, sensors, cables and all installation accessories. We supply installation drawings, electrical schematics, operation manuals and maintenance handbooks along with delivery.
