The utility model relates to a bucket elevator, transporting the hopper assembly of material being used for in the bucket body including bucket body and assembly, being equipped with the feed inlet onthe bucket body, hopper assembly is including being used for the hopper, bucket elevator still including set up feed inlet department be used for to the quantitative feeder of material in order to avoid the material to overflow is thrown from the hopper to the ration in the bucket body. In the bucket elevator working process, the material under quantitative feeder's effect by even distribution tothe bucket body in, quantitative feeder's single feed volume is no longer than the volume of hopper to avoid the material to overflow from the hopper, comparing in prior art, reducing or avoid material piling up in the bucket body, the hopper is difficult to worn and torn, and hoist mechanism resistance to motion is less, moves power saving more, work that bucket elevator can be better.
