[0002] Currently, feeders widely used in my country's coal, metallurgy, and power industries feature side panels on the upper hopper that are inserted into the feeder trough. These panels are typically small, and sufficient clearance must be maintained between them and the feeder trough for proper operation. This often results in material leakage or backflow, requiring manual cleaning that increases workload and pollutes the working environment. There is a particular need for a chute feeder with seamless hopper side panels that prevents leakage or backflow, without impacting the feeder foundation, and with high efficiency and stable operation.
