The following terms of orientation "top", "bottom", etc. are used with reference to the illustration of fig. 1 to refer to "front end" toward the door side and "rear end" conversely.
The first embodiment is as follows:
the embodiment provides a dry bulk container and a dry bulk container unloading method.
The dry bulk container of this embodiment is reformed transform on 20 feet dry bulk container and is formed, 20 feet dry bulk container includes the box, the box has roof 22, floor 12 (preferred iron floor), left side wall 1, right side wall 21, headwall, wherein, left side wall 1, right side wall 21 and headwall are located between roof 22 and floor 12, roof 22, floor 12, left side wall 1, right side wall 21 and headwall enclose into the open-ended cube of one end, open the end and form the case mouth, case mouth department is equipped with chamber door 20 for seal the case mouth. In this embodiment, three feed openings 23 are provided in the top wall 22 at equal intervals in the longitudinal direction of the dry bulk container for feeding dry bulk into the container body, each feed opening 23 being provided with a feed opening cover (not shown). Preferably, the feed port 23 is a circular port and the feed port cover is a circular cover. Of course, the number of the feed ports 23 may also be a plurality of 3, for example, 2; the feed opening 23 may also be a square opening.
In this embodiment, in addition to the above-described structure, referring to fig. 1 to 4, in the box body, a retaining wall for closing the box opening is fixed to the inner side of the box door 20 (the box door of the 20-foot dry bulk container is continuously used), the retaining wall is mainly formed of a metal plate (e.g., an iron plate), and the upper, lower, left, right edges of the retaining wall are welded to the box opening inside the box door 20. Of course, the method for closing the box opening by the retaining wall is not limited to welding, and retaining walls made of other materials and fixing methods can be adopted.

The fixed plate 24 is fixed to the two vertical rods of the bracket 27 and the floor, and the fixed plate 24 has a through hole aligned with the discharge opening 11. The discharge container 10 is fixed to a side of the fixing plate 24 facing the door, the discharge container 10 is aligned with the discharge opening 11, and the discharge opening door 13 can be moved along the inner end of the discharge container 10 to selectively block the communication between the discharge container 10 and the discharge opening 11. When the discharge port door 13 is inserted between the discharge port door and the discharge cylinder, the discharge port 11 is blocked from the discharge cylinder 10, and the discharge port 11 is closed; when the discharge port door 13 is not inserted therebetween, the discharge port 11 communicates with the discharge vessel 10, the discharge port 11 is opened, and dry bulk can be discharged through the discharge port 11 and the discharge vessel 10. The discharge shaft 10 is provided to facilitate connection with subsequent means for collecting dry bulk material to ensure that the transport of the dry bulk material is sealed and thus prevent contamination of the environment and health of the operator. The shape of the discharge cylinder 10 is not limited to the illustrated cylinder, and may be a square cylinder or a cylinder having another shape as long as it can be connected to a subsequent collecting device. Of course, depending on the subsequent collecting device selected, the discharge vessel 10 can also be dispensed with.
