Background

In the transportation process of a conveying system of a belt conveyor, as the belt is few and dozens of meters, and more, the belt is many and hundreds of meters, the problems that the belt deviates from a central line in operation and the like easily occur, and the belt deviation comprises the following reasons: firstly, because the processing technology of irregularity in band conveyer's the manufacture process leads to the belt head unevenness, consequently in actual operation, the belt of unevenness can arouse that both ends atress is inhomogeneous to lead to the appearance of off tracking trouble. And secondly, the belt conveyor has high standard of installation quality in installation, especially when a large belt conveyor is installed. When the device is installed, if the rack is inclined, the deviation phenomenon is easy to occur, and the adjustment and restoration are difficult. Thirdly, in the operation process, the deviation accident can be caused by the influence of foreign matters and vibration and the self abrasion.

A further reason for belt deviation is that the belt is affected by the difference in the drop point, and during loading, if the drop point is deflected in one direction, the belt is deflected to the other side under the impact force.

In various belt conveyor conveying systems, a blanking point is arranged to easily generate a large amount of dust hitting and belt deviation, and improvement is needed to be made in order to solve the belt deviation condition caused by the blanking point and solve the problems of dust removal and dust fall.
