[0038] The guide mechanism includes a guide column 75 arranged at the lower part of the two end surfaces 5, a guide sleeve 74 that can move up and down is arranged on the guide column 75, and guide plates 71 with guide grooves are arranged on both sides of the guide sleeve 74. The guide grooves include vertical guide grooves 72 arranged at the upper part of the two guide plates 71, and the lower ends of the two vertical guide grooves 72 are arranged with oblique guide grooves 73 inclined outward; the end plate 64 of the discharge door 6 is provided with a guide shaft 67 that cooperates with the guide groove. When the guide shaft 67 is located in the vertical guide groove 72, the discharge door 6 is in a closed state, and the process of the guide shaft 67 sliding downward along the vertical guide groove 72 and the oblique guide groove 73 is the opening process of the discharge door 6; a corresponding guide hole is arranged between the guide sleeve 74 and the guide column 75. After the locking pin 77 is inserted into the guide hole, the guide shaft 67 is locked in the vertical guide groove 72, and the discharge door 6 is in a closed state. The end guide mechanism is combined with the guide groove, so that the discharge door 6 can slide along a predetermined track during discharge to ensure smooth opening and closing. A locking pin 77 is provided between the guide sleeve 74 and the guide column 75 to effectively fix the discharge door 6 to prevent accidental opening during transportation.

[0039] An operating handle 76 is provided on the guide sleeve.

[0040] The bottom outer sides of the two discharge doors 6 are both provided with support blocks 61. When the box body 1 falls to the ground, the support frame contacts the ground, which can help the discharge door 6 to close naturally under the action of gravity.

[0041] A waterproof baffle 41 is provided at the lower part of the side 4 corresponding to the connection between the discharge door 6 and the side 4; and a leak-proof baffle 63 is provided at the connection between the two discharge doors 6 to prevent rainwater or cargo leakage.

[0042] The side surface 4, bottom surface and both end surfaces 5 of the box body 1 are provided with reinforcing beams 8 to enhance the structural strength, improve the impact resistance and prolong the service life.

[0043] The unloading process of the present invention is as follows: after the container is transported to the designated unloading site, the operator uses a lifting device or other handling tools to place the container 1 in an area suitable for unloading. At this time, it is ensured that the container 1 is in a stable state and that there is enough space under the unloading door 6 at the bottom of the container for the goods to flow out.

[0044] Unloading through the top opening: The operator uses the L-shaped handle to unlock the tarpaulin lock rod 25, so that the tarpaulin lock hook 23 is separated from the tarpaulin lock ring 24. Then, the sprocket of the tarpaulin opening system is rotated, so that the driving sprocket 211 drives the transmission chain 29, thereby driving the tarpaulin reel to rotate, gradually rolling up the waterproof tarpaulin and storing it to one side, and completely opening the top opening. Unloading can be carried out from the top opening.

[0045] Unloading through the unloading door 6: The end of the unloading door 6 is locked by a guide mechanism to prevent accidental opening during transportation. Before unloading, it is necessary to pull out the pin between the guide sleeve 74 and the guide column 75 so that the guide sleeve 74 can move freely on the guide column 75, thereby releasing the fixed state of the unloading door 6.

[0046] When the pin is pulled out, the bottom discharge door 6 starts to turn down under the action of its own weight. The guide column 75 of the end plate 64 of the discharge door 6 slides down along the vertical guide groove 72 under the action of the guide groove, and gradually enters the inclined guide groove 73 under the action of gravity, and finally turns completely to the open position, so that the bottom plate 66 of the discharge door 6 is separated to form a spacious unloading channel.

[0047] Due to the effect of gravity, the bulk cargo in the box body 1 flows out directly along the opened discharge door 6. When cargo residues are present during the flow process, the cargo can be completely unloaded by slightly vibrating the box body 1, using auxiliary tools or manual intervention.

[0048] After the goods are unloaded, the box body 1 is placed in a stable position again. The unloading door 6 gradually falls back to the original closed state under the action of gravity, and the guide column 75 on the end plate 64 of the unloading door 6 slides back along the guide groove into the vertical guide groove 72. When the unloading door 6 is completely closed, the fixed chain pin is inserted to ensure that the unloading door 6 is locked to prevent accidental opening due to vibration during transportation.

[0049] The sprocket mechanism is used to drive the tarpaulin reel to rotate in the opposite direction, unrolling the waterproof tarpaulin from the reel and completely covering the top opening of the box body 1. Subsequently, the tarpaulin locking rod 25 is reset so that the lock hook re-hooks the tarpaulin locking ring 24, and the tarpaulin latch 27 is inserted to ensure that the tarpaulin will not loosen or open accidentally during transportation.

[0050] The overall box body 1 of the present invention is designed based on the external dimensions of a standard container, and meets the requirements of sea and land transportation for containers.

[0051] The top opening is set as an integral opening. Compared with the multi-point or partial openings of traditional bulk containers, the integral opening design is more convenient for rapid loading and unloading of goods and improves loading efficiency.

[0052] The side surface 4 and end surface 5 of the box body 1 adopt a segmented structure (the upper end plate, side plate structure, and the lower unloading door 6 structure). The upper fixed structure ensures the structural strength of the box body 1. The lower unloading door 6 structure is fixed to the upper structure through a long hinge 62, and the opening and closing stroke of the lower unloading door 6 is controlled by the guide mechanism at the end. It can be understood that the above specific description of the present invention is only used to illustrate the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those skilled in the art should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the protection scope of the present invention.
