Description

Technical Field

[0001] The utility model relates to the technical field of containers, and more specifically, to a discharge door for a bulk cargo container. Background Art

[0002] Bulk cargo is an indispensable product in our daily life, and the transportation volume is also huge. For the traditional bulk cargo transportation method, the sea transportation method used by the vast majority has considerable losses and is not very efficient. However, the rapid development of container transportation, coupled with the many advantages of container transportation such as cost savings, reduced damage and leakage rates, and a large coverage of transit points, has made it a new mainstream trend to transport bulk cargo. Therefore, many domestic ports have begun to explore and develop the technology of container transportation of bulk cargo. The container transportation method first appeared in the 1860s and is a significant technological reform in the modern transportation industry. Compared with other modes of transportation, it has higher loading and unloading efficiency, faster ship turnover, less cargo damage and loss, lower labor intensity, lower insurance premiums and simpler procedures. At present, my country has formed an international container transportation network centered on my country that can reach ports around the world. Water transportation has a very long history, including inland river transportation and maritime transportation. In the total volume of international trade, more than 2 / 3 of cargo transportation is completed by water transportation.

[0003] For example, application No. 201310481721.4 discloses a discharge door structure and a bulk container. The discharge door structure includes a door frame, a door panel, a door seal and a protective structure. The door frame includes a relative connecting end and a free end; the door panel is fixed in the door frame; the door seal is installed around the door frame; the protective structure is a rigid structure, which is arranged at the free end of the door frame or adjacent to the free end, and protrudes from the inner side or bottom end surface of the free end of the door frame so as to be able to contact the materials discharged from the bulk container during the discharge process. During the discharge process of the bulk container, the protective structure can first contact the materials discharged from the bulk container to reduce or even avoid the contact between the door seal and the materials, thereby protecting the door seal from the wear of the materials. The sealing performance of the discharge door structure and the bulk container equipped with the discharge door structure is improved.

[0004] However, the existing bulk containers have large structural gaps, which are not conducive to bulk cargo of powdery or granular objects. In addition, the sealing performance is generally achieved by means of sealing strips or seals, which are too costly, too complex in structure, and inconvenient to produce and use. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a discharge door for a bulk container to solve one or more of the above-mentioned problems.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A discharge door for a bulk container, comprising a container, wherein a discharge mechanism is provided below the side of the container, wherein the discharge mechanism comprises

[0008] A discharge door, the upper end of which is hinged to the discharge port of the container through a hinge structure;

[0009] baffles, which are welded to the upper and lower ends of the outer side of the discharge door;

[0010] A bottom beam, which is arranged at the bottom of the discharge port of the container;

[0011] The baffle blocks the gap between the top end of the discharge door and the container, and between the bottom end of the discharge door and the bottom beam.

[0012] Furthermore, a lock is provided on the container, and the lock is pressed down to restrict or lifted up to cooperate with the flipping of the discharge door.

[0013] Furthermore, a door frame beam is also provided at the upper end of the discharge port of the container, and the door frame beam is located on a side where the discharge door is hinged to the hinge structure and is close to the container.

[0014] Furthermore, the door frame beam blocks the gap between the unloading door and the container.

[0015] Furthermore, the cross-section of the door frame beam is a tortuous stepped structure, and the end thereof covers the upper end of the inner side of the discharge door.

[0016] In summary, the utility model has the following beneficial effects:

[0017] 1. By welding the baffle plate to the discharge door, the internal bulk cargo is sealed, which is lower in cost than sealing with rubber strips;

[0018] 2. The structure of the unloading part has been simplified and improved, making it easy to produce and reliable to use;

[0019] 3. By adding door frame beams to reduce the gap between the unloading door and the container unloading port, the baffle will also enhance the sealing effect in the natural hanging state, and meet the sealing requirements with the help of the friction between the bulk cargo and the components.

[0024] Example:

[0025] The following is combined with Figure 1-3 The utility model is described in further detail.

[0026] A bulk container discharge door 2, such as Figure 1 As shown, the unloading mechanism is arranged at the unloading port below the side of the container. The unloading mechanism, mainly the unloading door 2, is hinged to the container through a hinge structure 1, that is, the upper end of the unloading door 2 is hinged to the container unloading port through the hinge structure 1, and the unloading door 2 can rotate around the upper unloading mechanism as an axis to form a bottom-opening unloading mechanism. A bottom beam 6 is arranged below the unloading port, and the bottom beam 6 mainly plays the role of structural enclosure and restriction and buffering of the flipping action of the unloading door 2. A lock 3 is arranged on the container. The function and structure of the lock 3 are similar to the function of the opening and closing door stopper on the container truck. The lock 3 has two actions, one is to lift away from the unloading door 2 to cooperate with the normal flipping of the unloading door 2, and the other is to lower and seal the unloading door 2 to limit the flipping of the unloading door 2.

[0027] like Figure 2 and Figure 3 As shown, the outer side of the discharge door 2, that is, the side away from the container, is provided with corresponding baffles 5 at the upper and lower ends, and the baffles 5 replace the sealing strips to seal the internal bulk cargo. The discharge door 2 mainly blocks the gap between the top of the discharge door 2 and the discharge port of the container, and also blocks the gap between the bottom of the discharge door 2 and the bottom beam 6.

[0028] A door frame beam 4 is also provided at the upper end of the container discharge port. Figure 3 As shown, it is a stepped section that twists and turns from outside to inside. The door frame beam 4 is located between the hinged structure, the discharge door 2 and the container, and plays the role of blocking the internal bulk cargo in multiple sections and directions. The door frame beam 4 blocks the gap between the discharge door 2 and the container that is not completely blocked by the baffle 5, and strengthens the internal sealing. The end of the door frame beam 4 has an additional vertical extension, which covers the upper end of the inner side of the discharge door 2 to a certain extent, which is more rigorous and scientific.

[0029] Instead of the sealing strip, the baffle 5 is used to block and reduce the gap between the discharge door 2 and the container. Under the action of gravity, the bulk cargo can fill the area that cannot be actually blocked on the corresponding structure, and further leakage is limited under the action of friction, meeting the sealing requirements. The structure is simple, the production is convenient, the use is reliable, and the cost is lower. Lift the lock 3 to unload, and put down the lock 3 to achieve blocking. It is suitable for the transportation and filling of powdery or granular bulk cargo in the box, and is easy to maintain.

[0030] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
