DETAILED DESCRIPTION

[0028] As shown in the accompanying drawings, this embodiment provides a grain storage container with an inflatable rubber strip, including a base frame 1, and the base frame 1 is a standard container base frame 1 structure in the form of a steel floor.

[0029] Two side wall panels 3 with top beams 2 are connected to the left and right sides of the bottom frame 1. The side wall panels 3 are different from the side wall panels 3 of the standard container with a corrugated depth of 36 mm. They are made of 700Mpa high-strength steel with a corrugated depth of 56 mm, and the structure is more reliable.

[0030] The front side of the chassis 1 is connected with a front frame 4, which is a container front frame of a standard structure. The front frame 4 is wrapped with a front wall panel 5, which is made of 700Mpa high-strength steel, and has a more reliable structure.

[0031] A rear frame 6 is connected to the rear side of the base frame 1. The rear frame 6 includes corner fittings 10 at four corners, the corner fittings 10 connected with the upper door lintel 11, the lower door sill 12 and the outer corner columns 13 on both sides to form a rectangular frame.

[0032] The threshold 12 is a multi-sided curved inclined structure, which effectively prevents external water from seeping into the box. Anti-collision channel steels 22 are arranged between the two sides of the threshold 12 and the corner fittings 10 on the two sides of the bottom.

[0033] The lintel 11 is provided with a lintel board 14, which is connected to the top wall board 7, the inner side of the outer corner column 13 is connected to the inner side of the inner corner column 15, and the threshold 12 and the inner side of the lintel 11 are both connected with a transverse rubber strip fixing angle steel 16, which can effectively prevent the grain particles in the box from leaking out.

[0034] A vertical rubber strip fixing angle steel 17 is connected to the inner side of the inner corner column 15, and the horizontal rubber strip fixing angle steel 16 and the vertical rubber strip fixing angle steel 17 form a rectangular frame and are fixed with frame inflatable rubber strips 18, and all frame inflatable rubber strips 18 are connected, and frame sleeves 19 connecting the inside of the frame inflatable rubber strips 18 and the inside of the box body are provided on the inner corner column 15 and the lintel 11, and a frame rubber strip booster valve 20 facing the inside of the box body is fixed on each frame sleeve 19.

[0035] By using special nitrogen filling equipment to ensure accurate and stable nitrogen filling amount, when the nitrogen concentration and pressure in the container reach the use requirements, the frame inflation strip 18 uses the nitrogen in the box to pressurize through the added valve, and the pressure is higher than that in the box, thereby realizing automatic inflation and self-sealing.

[0036] A bottom boost valve 21 for fixing the corresponding frame inflatable rubber strip 18 is provided on the threshold 12. The bottom boost valve 21 passes through the inner wall of the bottom frame inflatable rubber strip 18 and is inserted into the hole provided on the threshold 12. The bottom boost valve 21 only serves to fix the frame inflatable rubber strip 18 to the threshold 12. Since all the frame inflatable rubber strips 18 are connected, the nitrogen introduced through the other three sections of the frame inflatable rubber strips 18 enters the frame inflatable rubber strip 18 corresponding to the threshold 12 to inflate the frame inflatable rubber strip 18 corresponding to the threshold 12.

[0037] The front frame 4, top beam 2 and upper side of the rear frame 6 are connected with a top wall panel 7. Different from the standard container top panel with a corrugated depth of 25mm, this top wall panel 7 is made of 700Mpa high-strength steel and a top panel with a corrugated depth of 34mm, and the structure is more reliable.

[0038] The rear end frame 6 is hinged with a door assembly 9 via a hinge 8. The door assembly 9 includes a left door leaf 23 and a right door leaf 24. The left side of the left door leaf 23 and the right side of the right door leaf 24 are respectively connected to the hinge 8 on the rear end frame 6, so that the left door leaf 23 and the right door leaf 24 can open and close from the middle of the rear end frame 6 to both sides.

[0039] A hollow L-shaped door vertical beam 25 and a hollow inverted L-shaped door vertical beam 26 that cooperate with each other are respectively arranged on the right side of the left door leaf 23 and the left side of the right door leaf 24 (as shown in the figure, the L-shaped door vertical beam 25 is arranged on the left door leaf 23, and the inverted L-shaped door vertical beam 26 is arranged on the right door leaf 24). The long side of the L-shaped door vertical beam 25 is close to the outside of the box body, and the long side of the inverted L-shaped door vertical beam 26 is close to the inside of the box body. Since the inverted L-shaped door vertical beam 26 is larger in size, in order to simplify the production process of the inverted L-shaped door vertical beam 26, the inverted L-shaped door vertical beam 26 is welded together by two multi-folded special-shaped vertical beams.

[0040] The L-shaped door vertical beam 25 is provided with a door angle steel 27, and a door inflation rubber strip 28 is fixed on the door angle steel 27. The door inflation rubber strip 28 is located between the L-shaped door vertical beam 25 and the inverted L-shaped door vertical beam 26 and is closely attached to the inverted L-shaped door vertical beam 26 after inflation. Due to the multi-folding design of the inverted L-shaped door vertical beam 26, the sealing between the frame inflation rubber strip 18 and the door inflation rubber strip 28 is effectively achieved. The sealing between the center of the left door leaf 23 and the right door leaf 24 is ensured.

[0041] A vent hole 29 is provided on the inverted L-shaped door vertical beam 26 corresponding to the door inflatable rubber strip 28 for connecting the inflatable rubber strip with the interior of the container, and a door rubber strip pressure boosting valve 30 is provided on the vent hole 29 near the door inflatable rubber strip 28. The door rubber strip pressure boosting valve 30 faces the hollow interior of the inverted L-shaped door vertical beam 26. After the door is closed, the inflation principle of the door inflatable rubber strip 28 is the same as that of the frame inflatable rubber strip 18. When the door is closed, the door assembly 9 cooperates with the frame inflatable rubber strip 18, and the sealing of the container door end is achieved through the inflation of the door inflatable rubber strip 28 and the frame inflatable rubber strip 18.

[0042] A door sleeve 31 is also provided on the L-shaped door vertical beam 25 , and the door inflation strip 28 and the door angle steel 27 are tightened and fixed to the L-shaped door vertical beam in the door sleeve 31 through a fastener 32 .

[0043] In addition, a locking rod assembly 33 is cooperatively provided on the left door leaf 23 and the right door leaf 24 for locking the left door leaf 23 and the right door leaf 24 .

[0044] This grain storage container can meet the needs of mixed and classified storage of grain, and through nitrogen preservation technology, it can ensure that the quality and safety of stored raw grains and finished grains are better within the same rotation cycle.

[0045] 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.
