AI Technical Summary
In coal conveying systems, coal hoppers are prone to blockage due to increased friction between coal particles and between coal particles and the hopper walls. Existing unblocking methods affect production continuity.
The coal hopper body is designed with alternating inclined and vertical sections, and is equipped with a vibrating ball and vibrating plate assembly. Through vibration, the superposition effect of friction is decomposed, preventing coal particles from being rubbed and retained on the inner wall.
It effectively reduces coal particle blockage, ensures the continuity and consistency of coal conveying operations, and avoids production interruptions.
