[0002] In my country, coal is mined and transported to its destination by rail. Loading stations are crucial for this process. Currently, when loading train cars at loading stations, the angle of the material stack creates a conical pile, requiring external force to flatten the pile across the width of the train car. Due to the high moisture content (typically around 20%) and viscosity of the mixed coal, loading into the cars is prone to front-to-back load imbalance, which violates railway transportation regulations. To address this issue, two commonly used methods are manual coal leveling and mechanical fixed coal leveling. Manual coal leveling is inefficient, time-consuming, and carries significant safety risks. Mechanical fixed coal leveling, which comes in two types: plate-type and spiral-type. While they can replace manual labor, mechanical fixed coal leveling machines can only move vertically up and down the train. Because loading can be unpredictable, the train driver must control the forward and backward movement of the traction train. This makes coordination difficult, operability poor, and inefficient. More importantly, it violates railway safety regulations. Utility Model Content
