AI Technical Summary

Technical Problem

Existing traditional coal feeders and tractor belt scales suffer from inaccurate metering and belt misalignment during raw coal transportation, resulting in insufficient weighing accuracy and impacting production efficiency.

Method used

A high-precision raw coal weighing belt scale is used, combined with a laser displacement sensor and triggering components, to monitor belt offset and pressure distribution in real time. Data is transmitted to the control terminal via a wireless unit for correction and regulation, ensuring stable belt operation.

Benefits of technology

It enables precise control over the belt conveyor process, significantly improves the accuracy of raw coal weighing, reduces weighing errors caused by belt misalignment and uneven material distribution, and ensures the economic benefits of the production system.
