In most of existing bucket elevators, a hopper is filled with materials from a feeding port at a low position, and when the materials are poured from a discharging port, the materials are scattered from gaps to the bottom of the bucket elevator to be deposited due to the fact that the feeding port, the discharging port and the hopper are large in gaps. At present, the common solutions are to increase the opening degree of the discharge port, to adjust the connection state between the feed port and the discharge port and the hopper, or to arrange a material collecting port for collecting the scattered materials below the bucket elevator and to transport the scattered materials back to the material bin by a conveyor belt or a trolley.

For example, patent CN202213946U provides a bucket elevator, which adds a movable material guiding hopper and a return spring to the discharging port, and when the hopper presses down the material guiding hopper, the return spring completes the return, thereby avoiding the problems of material scattering and material accumulation during the discharging process. For another example, patent CN206645414U provides a bottom blanking system of a bucket elevator, in which a feeding end of a blanking plate is connected to a discharge port of the feeding reamer and is inclined at a certain angle, and a blanking end of the blanking plate is located below the feeding end and directly above the hopper to eliminate a gap between the feeding end and the hopper and reduce scattering of materials. The effect of preventing the materials from scattering of the bucket elevator is only bad, the materials are likely to scatter from two sides when entering the hopper and being led into the discharge port from the hopper, and particularly in the field of concrete building materials, the used composite fiber anti-cracking agent is a mixed material of powder and short fibers, the quality is easy to scatter, so that dust or fibers are everywhere in the bucket elevator, and a large amount of dust fibers are accumulated on a rack.
