[0002] The bucket elevator is a commonly used material conveying equipment, which is usually used for vertically or obliquely conveying granular, block or powder materials. It is composed of a driving device, an external housing, a conveying device and other components. The working principle of the bucket elevator is to use the conveying belt to ascend or descend the hopper containing materials along the lifting mechanism of the elevator, thereby realizing the vertical conveying of the materials. When the elevator is working, the hopper circulates along the conveying belt to convey the materials from the lower part to the upper part or vice versa. The bucket elevator is mainly applied in the fields of cement, ore, fertilizer and grain, and is used for conveying granular or block materials. It has the advantages of large conveying capacity, small floor area, simple structure, convenient maintenance and the like, and is widely applied in various production lines to improve the production efficiency and the efficiency of material conveying.

[0003] The existing bucket elevator still has some deficiencies, i.e., the rotational speed of the driving source motor is too large in the working process of the bucket elevator, and the rotational speed required by the bucket elevator should be relatively small, otherwise the materials cannot be accurately thrown into the designated position due to the excessively large ascending speed of the materials, and the bottom of the bucket elevator will also appear the phenomenon of material stacking in the working process, so that the material conveying cannot be realized more thoroughly. In addition, the bucket elevator needs to be frequently moved in some special working conditions, and the portable elevator needs to consume a large amount of manpower for carrying, disassembling and installing.
