The unloading process of the present invention involves the operator using lifting equipment or other handling means to place the container 1 in an area suitable for unloading after the container has been transported to the designated unloading site. At this time, the case 1 is ensured to be in a stable state, and a sufficient space is ensured under the bottom discharge door 6 for the outflow of the cargo.
The cargo is unloaded through the top opening, and an operator uses an L-shaped handle to unlock the tarpaulin locking rod 25, so that the tarpaulin locking hook 23 is separated from the tarpaulin locking ring 24. Then, the sprocket of the tarpaulin opening system is rotated, so that the driving sprocket 211 drives the driving chain 29, thereby driving the tarpaulin reel to rotate, gradually rolling up and storing the tarpaulin to one side, and completely opening the top opening. The discharge can take place from the top opening.
The unloading is carried out through the unloading door 6, and the end part of the unloading door 6 is locked through a guide mechanism so as to prevent the misoperation in the transportation process. Before unloading, a pin shaft between the guide sleeve 74 and the guide post 75 needs to be pulled out, so that the guide sleeve 74 can freely move on the guide post 75, and the fixed state of the unloading door 6 is released.
When the pin shaft is pulled out, the box bottom unloading door 6 starts to turn down under the action of dead weight. The guide posts 75 of the end plate 64 of the discharge gate 6 slide down the vertical guide slots 72 under the action of the guide slots and gradually enter the diagonal guide slots 73 under the action of gravity and eventually turn completely to the open position, separating the bottom plate 66 of the discharge gate 6 to form a wide discharge path.
Bulk cargo in the container 1 flows out directly along the opened discharge door 6 due to gravity. When residues appear in the goods flowing process, the goods can be ensured to be completely discharged through the modes of slightly vibrating the box body 1, using auxiliary tools or manual intervention and the like.
When the goods are discharged, the case 1 is replaced at a stable position. The discharge gate 6 gradually falls back to its original closed position under the force of gravity and the guide posts 75 on the end plate 64 of the discharge gate 6 slide back along the guide slots into the vertical guide slots 72. After the discharge door 6 is completely closed, a fixed chain pin is inserted to ensure that the discharge door 6 is locked so as to prevent accidental opening caused by vibration during transportation.
The tarpaulin reel is driven to rotate reversely by a chain wheel mechanism, the tarpaulin is unfolded from the reel and is completely covered on the top opening of the box body 1. Subsequently, the tarpaulin locking bar 25 is reset, so that the locking hooks hook the tarpaulin locking ring 24 again, and meanwhile, the tarpaulin bolt 27 is inserted, so that the tarpaulin cannot be loosened or accidentally opened in the transportation process.
The whole container body 1 is designed based on the external dimension of a standard container, and meets the requirements of sea and land transportation on the container.
The top opening is set to be an integral opening, and compared with a multi-point or partial opening of a traditional bulk container, the integral opening is designed to be more convenient for rapid loading and unloading of cargoes, and loading efficiency is improved.
The side surface 4 and the end surface 5 of the box body 1 adopt sectional structures (an upper end plate, a side plate structure and a lower discharging door 6 structure), the upper fixing structure ensures the structural strength of the box body 1, the lower discharging door 6 structure adopts and is fixed on the upper structure through a long hinge 62, the opening and closing stroke of the lower discharging door 6 is controlled through a guide mechanism at the end part,
It should be understood that the foregoing detailed description of the present invention is provided for illustration only and not for limitation, and it should be understood by those skilled in the art that the present invention may be modified or substituted for the same technical effects and is within the scope of the invention as long as the usage requirement is satisfied.
