The winch is positioned on one side of the portal far away from the extending end of the arm support, one end of the steel wire is wound on the winch, the other end of the steel wire sequentially bypasses the lower bend pulley and the upper bend pulley, sequentially and alternately bypasses corresponding pulleys on the upper wheel set and the lower wheel set from the same side, and then is fixed on the arm support beside. When the device works, the belt conveyor is connected below the arm support, and the discharge end of the belt conveyor is positioned at one end of the extending end of the arm support. By forward and reverse rotation of the winch, the arm support can be adjusted in pitch around the hinged end of the arm support, and then the height of the discharge end of the belt conveyor is adjusted, so that bulk materials are discharged at the highest position of a storage yard. Because the portal is fixed, the upper bend pulley and the upper wheel set are fixedly connected with the portal, when the arm support rotates, the portal, the upper bend pulley and the upper wheel set cannot rotate along with the arm support, so certain relative displacement can be generated, the steel wire rope deviates from the pulley rope grooves of the upper bend pulley and the upper wheel set fixed on the upper part of the portal, and the friction force between the steel wire rope and the rope grooves is increased. Therefore, the acting force of the steel wire rope is weakened, the abrasion of the steel wire rope is accelerated, and the service life of the steel wire rope is shortened.
