It can also be removed without stopping the machine, without affecting the normal operation of the belt conveyor. When adjusting the position of the drop point, it is prevented that the belt deviates due to uneven material drop. The impact force of the drop on the belt can be reduced by adjusting the angle and height. It can be suitable for conveying at different angles, reduce the damage to the belt caused by excessive friction, impact and belt deviation, increase the use range of the guide trough, and increase the service life of the machine body and the belt.
