First, there is no impact between the package and the bucket during loading and transporting of the package. Therefore, the probability of abrasion of the bucket is reduced. In addition, even a fragile package can be transported in a circle without damage to the package.

Second, because the amount of the package contained in the bucket is constant, there is no change in the load, the use power is less.

Third, compared with the conventional outer bucket conveyor, the amount of the package flowing out of the bucket is minimal, and since the residue of the package remains little inside the drum assembly, the conveying capacity representing the practical ratio to the bucket volume reaches almost 100%.

Fourth, in the case of a conventional outer bucket conveyor, when the conveying member such as a chain is stretched, the tooth joining becomes poor, and thus the operation is inferior. However, according to the present invention, the drum assembly is vertically moved by the slider to extend the conveying member. It can increase the adaptability to.

Fifth, since the discharge chute is installed inside the head pulley to receive the package by free fall, the case of the package can be prevented from overflowing, thereby increasing the transfer efficiency.

Sixth, the sealing structure in the drum assembly and the structure of installing the bucket on the inner circumferential surface of the conveying member can completely convey one kind of package, thereby having the advantage of continuously conveying two or more kinds of packages.
