Background

The belt conveyor is a belt conveyor for short, and has the advantages of fixed type, movable type, simple structure and high efficiency. A continuous conveyor machine for carrying and pulling material on a flexible conveyor belt. An endless conveyor belt is looped around the drive rollers and the direction-changing rollers. The upper and lower branches between the two rollers are supported by a plurality of carrier rollers. The materials are placed on the upper branch, and the conveying belt and the materials are dragged to run by utilizing the friction force between the driving roller and the belt. The conveying device is suitable for conveying bulk materials and finished articles in horizontal and inclined directions, and can also be used in a production line for certain process operations.

The problem that ordinary belt feeder had the material in transportation process, and current improvement mode is side formula returning charge belt, unloads the material of belt frame chute board upper end part to the returning charge belt through gathering materials on, and the returning charge belt will fall the material and carry to flat belt or current oblique belt bottom to realize falling exempting from of material and clear up.

However, the side-mounted material returning belt has the following disadvantages: firstly, the method can only collect the aggregate above a small section of chute board on the upper part of the inclined belt, but can not collect most residual materials; the falling materials are easy to accumulate at the upper part, and the materials need to be shoveled to a discharge hopper manually so as to be recycled; thirdly, the falling materials contain large water and mud, are easy to condense at the discharge opening and need to be cleaned regularly; and fourthly, more material throwing points are generated in the recovery process, and secondary material scattering and material dropping are easily caused.
