[0016] Embodiment 1: As shown in Figure 1 、 2 A loading mechanism of a ship unloader includes a bidirectional belt conveyor 4 and a material receiving hopper 1 that feeds materials to the bidirectional belt conveyor; a blanking hopper is provided below one end of the bidirectional belt conveyor 4, and an inclined blanking connector 7 is provided at the tail end of the blanking hopper; a blanking pipe 8 with one end hinged is provided on the side of the blanking connector 7, the tail of the blanking pipe 8 is connected to a lifting mechanism, and the blanking pipe 8 rotates around the hinge point and is sleeved with the blanking connector 7; a dust cover 6 is installed at the tail section of the blanking pipe 8;

[0017] The lifting mechanism uses a winch 9, the winch is installed on a column, and forms a lifting mechanism through a pulley 10 installed on another column, a pulley 10 installed at the tail of the blanking pipe 8, and a steel wire rope 12. A safety rope 11 is connected to the middle of the blanking pipe 8, and the other end of the safety rope 11 is connected to the middle column. The bidirectional belt conveyor 4 is installed on the boom or gantry of the ship unloader. An outlet belt conveyor 5 is provided below the other end of the bidirectional belt conveyor 4. The column and the middle column can be fixed to the dock, and the position is set back to avoid interference.

[0018] As in the case of conventional unloading, the bulk materials sent by the grab of the ship unloader are continuously filled from the top of the material receiving hopper 1, and during this period, the bottom of the material receiving hopper 1 is also continuously discharging materials into the bidirectional belt conveyor 4. The bidirectional belt conveyor 4 rotates forward, and the materials slide onto the outlet belt conveyor 5, and then the outlet belt conveyor 5 slides onto the dock belt conveyor.

[0019] When the bidirectional belt conveyor 4 rotates in reverse, the steel materials on the belt slide through the blanking connector 7 to the blanking pipe 8 and then slide onto the vehicle.

[0020] After the vehicle is fully loaded, stop the two-way belt conveyor 4, and one working process ends. When the loading mechanism is not in use, through the hoist 9 and the pulley 10, the material dropping pipe 8 is retracted to the anchoring position; to avoid affecting the entry and exit of vehicles and prepare for the next time. To prevent the steel wire rope 12 of the hoist 9 from breaking, the safety rope 9 plays a protective role.

[0021] The two-way unloading of the utility model reduces the use of the belt conveyor and avoids affecting unloading when the belt conveyor stops working, breaks down or is under maintenance; it has a dual protection function.

[0022] Embodiment 2:

[0023] In addition to including Embodiment 1, the receiving hopper 1 is installed on the main structure of the equipment through the weighing device 2, and the receiving hopper 1 is provided with a flow regulating door 3; when the accumulated weight reaches the set range, the weighing device 2 will give an alarm, indicating that the filling should be paused.

[0024] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
