no. 1 approach

[0031] Such as image 3 As shown, the first embodiment of the discharge door structure of the present invention includes a door frame 131, a door panel 132, a door seal strip 133 and a protective structure.

[0032] The door frame 131 is, for example, rectangular, and is composed of opposite connecting ends, free ends and opposite two sides. The connecting end is rotatably connected to objects such as the box body, and the free end can rotate around the connecting end to open or close the discharge door.

[0033] The free end of the door frame 131 includes the inner side of the free end facing the inner direction of the discharge door, the outer side of the free end facing the outer direction of the discharge door, and the bottom end surface 1330 connecting the inner and outer bottom ends of the free end and respectively connecting The top face of the inner and outer top ends of the free end.

[0034] The door panel 132 is fixed inside the door frame 131 .

[0035] The door...

Embodiment approach 2

[0043] Such as Figure 4 As shown, the difference between the second embodiment of the discharge door structure of the present invention and the first embodiment only lies in:

[0044] The first protective structure is a support member 135 with one end welded and fixed on the inner side of the free end of the door frame 131 and inclined inwardly and downwardly relative to the door panel 132. The inclination angle θ is 30°. It is feasible, and it can be determined according to factors such as the opening angle of the discharge door. The supporting member 135 may protrude from the bottom surface 1330 of the free end of the door frame 131 by a certain height, or may not protrude. Usually, when the inclination angle θ is small, the support member 135 needs to protrude from the bottom end surface 1330 of the free end of the door frame 131, so as to avoid the inner sealing portion 1331 from contacting the material during the unloading process; The bottom surface 1330 of the free e...

Embodiment approach 3

[0048] Such as Figure 5 As shown, the difference between the third embodiment of the discharge door structure of the present invention and the second embodiment only lies in:

[0049] The first protective structure is a V-shaped piece 137. One end of the V-shaped piece 137 is fixed on the inner side of the free end of the door frame 131, and the other end is fixed on the free end of the door frame 131 adjacent to the inner sealing portion 1331. 137 is inclined inward and downward relative to the door panel 132 .

[0050] During the unloading process, the protruding tip of the V-shaped piece 137 contacts the bulk cargo and drags on the bulk cargo pile 200, while the inner sealing portion 1331 and the outer sealing portion 1332 are kept at a certain distance from the bulk cargo pile 200. Therefore, the door seal rubber strip 133 can be protected from being worn by bulk goods.

[0051] Other structures of the third embodiment of the discharge door structure of the present inve...

Abstract

The invention provides an unloading door structure and a bulk container. The unloading door structure comprises a door frame, a door sheet, a door sealing rubber strip and a protection structure, wherein the door frame comprises a connecting end part and a free end part, which are opposite to each other; the door panel is fixed in the door frame; the door sealing rubber strip is mounted at the periphery of the door frame; the protection structure is a rigid structure, is arranged at the free end part of the door frame or in a position near the free end part, and protrudes out of the inner side or the bottom end surface of the free end part of the door frame so as to be in contact with material unloaded from the bulk container in the unloading process. Through the application of the unloading door structure, in the unloading process of the bulk container, the protection structure can be firstly in contact with the material unloaded from the bulk container to reduce or even avoid contact between the door sealing rubber strip and the material, so that the door sealing rubber strip can be protected from being abraded by the material, and the sealing property of the unloading door structure and the bulk container with the unloading door structure is improved.

Description

technical field [0001] The invention relates to the field of bulk container transportation, in particular to a discharge door structure and a bulk container. Background technique [0002] Due to the widespread promotion of container transportation and the various advantages of containers, such as good watertightness, anti-theft, and one-stop delivery, more and more goods have begun to be transported in containers. In particular, bulk goods are transported in bulk containers, which can reduce secondary pollution during packaging, manpower loading and unloading, and transportation. [0003] Such as figure 1 As shown, the current bulk container 10 includes a bottom plate 11 and a box fixed to the bottom plate 11 . Generally, a discharge port 121 is provided at the lower part of the rear end plate 12 of the casing, and an upward-turning discharge door 13 is provided on the discharge port 121 . The discharge door 13 includes a rectangular door frame 131 and a door panel 132 fi...
