Description

Maintenance-free material correcting auxiliary device of coal conveying system Technical Field The utility model belongs to the technical field of coal transportation, and particularly relates to a maintenance-free material correcting auxiliary device of a coal conveying system. Background The situation that the belt is deviated frequently occurs in a coal transportation factory, and the main reason for the phenomenon is that the falling point after coal feeding is deviated too much so that the stress on the coal transportation belt is uneven after long-term practice. When the coal in the coal feeding bin is output to the coal conveying belt, the coal flow with a high flow speed is easy to fall along the left side wall or the right side wall of the feeding channel because of uneven flow of the coal, so that the coal is piled on one side of the coal conveying belt.
