To provide an unloader capable of eliminating the need of a drive device for rotating paddle and rotating screws and rotating the rotating paddle and the rotating screw independently of each other at any rotational speeds.

This unloader comprises a carrying conveyor 6 installed in a boom 2, the rotating paddle 3 installed at the tip of the boom 2 and delivering bulk materials to the carrying conveyor 6, and the rotating screws 4 installed at both sides of the rotating paddle 3 and taking the bulk materials therein and feeding to the rotating paddle 3. The rotating shaft 3a of the rotating paddle 3 and the rotating shaft 4a of the rotating screw 4 are formed coaxially with each other and so as to be rotated independently of each other. The unloader comprises a first transmission device 16 transmitting the drive force of the carrying conveyor 6 to the rotating shaft 3a of the rotating paddle 3 and a second transmission device 17 transmitting the drive force of the carrying conveyor 6 to the rotating shaft 4a of the rotating screw 4.
