[0001] The utility model relates to the technical field of grain storage, and specifically, to an overhead floor structure of an underground grain storage bin. Background Art

[0002] At present, most common granaries for storing grain are above-ground bins. With the innovation and development of technology, the design of building underground grain storage bins is gradually increasing.

[0003] The advantages of underground grain storage are that the underground space can use the soil body as a shield, which is more conducive to controlling the temperature of stored grain and can also prevent more natural disasters. It belongs to the category of green grain storage.

[0004] However, there are also some naturally existing problems in underground grain storage that need to be solved:

[0005] On the one hand, when storing grain underground, when the grain is transferred outwards, how to solve the problem of grain out-of-storehouse is one of the problems that need to be solved.

[0006] On the other hand, underground grain storage must face the problem of groundwater intrusion. How to solve problems such as groundwater leakage is the second problem that needs to be solved.

[0007] In order to solve the above existing problems, people have been seeking an ideal technical solution. Content of the Utility Model

[0009] To achieve the above purpose, the technical solution adopted by the utility model is: an overhead floor structure of an underground grain storage bin, including an underground grain storage bin and an overhead floor arranged below the underground grain storage bin. The underground grain storage bin includes a bin bottom, a bin wall and a bin top.

[0010] A number of grain outgassing gates are arranged on the bin bottom, and the grain outgassing gates are distributed in the interval areas of the cross beams;

[0011] A horizontal conveying mechanism for receiving and horizontally conveying grain corresponding to each grain outgassing gate is installed in the overhead floor bottom plate;

[0012] A drainage channel and a sump for drainage are also arranged on the overhead floor bottom plate.

[0013] Based on the above, a air distribution pipeline is distributed on the upper surface of the bin bottom, and the air inlet channel of the air distribution pipeline communicates with the outside.

[0014] Based on the above, a grain elevator for connecting each horizontal conveying mechanism is provided on the side of the underground grain storage bin.

[0015] Based on the above, a dedicated lifting channel is provided at the location where the grain elevator is to be installed in the underground grain storage bin.

[0016] Based on the above, the horizontal conveying mechanism in the overhead layer includes a plurality of first conveying mechanisms laid side by side and a second conveying mechanism for docking with each first conveying mechanism and perpendicular to the first conveying mechanism. The second conveying mechanism is docked with the lower end inlet of the grain elevator.

[0028] Next, through specific implementation manners, the technical solutions of the present utility model will be further described in detail.

[0029] As Figures 1-3 shown, an overhead floor structure of an underground grain storage bin includes an underground grain storage bin 1 and an overhead floor 2 provided below the underground grain storage bin 1. The underground grain storage bin 1 includes a bin bottom 11, bin walls and a bin top. The overhead floor 2 includes an overhead floor bottom plate 21, support columns 22 supported between the overhead floor bottom plate 21 and the bin bottom 11, and cross beams 23 connecting the support columns 22.

[0030] The overhead floor 2 supports the entire underground grain storage bin 1 and serves as a part of the foundation structure of the underground grain storage bin 1, mainly for installing grain discharging equipment.

[0031] A number of grain outlet gates 12 are provided on the bin bottom 11. The grain outlet gates 12 are distributed in the interval areas of the cross beams 23. The grain outlet gates 12 can be set to be manually triggered or remotely controlled. Specific gate opening mechanisms can adopt common means such as hydraulic and electric control.

[0032] A horizontal conveying mechanism 3 for receiving and horizontally conveying grains corresponding to each grain outlet gate 12 is installed in the overhead floor bottom plate 21. In this embodiment, it is a horizontal conveyor belt. Devices for preventing grain escape such as corresponding feed hoppers can be provided at each grain outlet gate 12. A grain elevator 7 connecting the horizontal conveying mechanisms 3 is provided on the side of the underground grain storage bin 1. A special lifting channel is provided at the location where the grain elevator is installed in the underground grain storage bin.

[0033] Specifically, the horizontal conveying mechanism 3 in the overhead floor 2 includes a plurality of first conveying mechanisms 31 laid side by side and a second conveying mechanism 32 for docking with each first conveying mechanism 31 and perpendicular to the first conveying mechanism 31. The second conveying mechanism 32 is docked with the lower end inlet of the grain elevator 7.

[0034] Generally, the first conveying mechanism 31 is arranged below each gate, and its outlet end is uniformly arranged on one long side of the overhead floor 2. The second conveying mechanism 32 is arranged on one long side of the overhead floor 2 to receive the grain transported out by the first conveying mechanism 31. After the grain is aggregated by the second conveying mechanism 32, it is uniformly transported to the grain elevator 7 and then transferred outdoors.

[0035] In other embodiments, when there is a height difference in the geographical environment of the area where the granary is built, a horizontal duct connecting the overhead floor 2 can also be built, with a horizontal conveying mechanism inside, which can be directly connected to the second conveying mechanism 32 to transfer the grain outdoors.

[0036] A drainage channel 4 and a sump 5 for drainage are also arranged on the overhead floor bottom plate 21, mainly to prevent seepage water from depositing inside the underground grain storage bin 1, but to deposit downward on the overhead floor bottom plate 21 and then be drained away through the drainage channel 4 and the sump 5.

[0037] To further solve the seepage problem, in a preferred embodiment, a water isolation structure, such as a waterproof layer or a double-layer hollow water isolation structure, is arranged on the outer wall of the underground grain storage bin, which isolates external seepage water on the one hand and cuts off the horizontal conduction of seepage water on the other hand, so that it deposits on the underlying overhead floor.

[0038] In addition, in this embodiment, to solve the problems of ventilation, moisture removal and temperature control of the underground grain storage bin 1, air distribution ducts 6 are distributed on the upper surface of the bin bottom 11, and the air inlet channels of the air distribution ducts 6 are communicated with the outside.

[0039] To improve the safety of the underground grain storage bin and facilitate daily inspection and maintenance, a staircase passage or an elevator shaft for people to vertically pass through is arranged inside or outside the underground grain storage bin 1, and a number of inspection doors are arranged on the path of the underground grain storage bin relative to the staircase passage or the elevator shaft.

[0040] The overhead floor structure of the underground grain storage bin effectively solves the problems of transporting grain out of the underground grain storage bin and groundwater intrusion, which promotes the application of the underground grain storage bin.

[0041] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still modifications can be made to the specific implementation manners of the present invention or equivalent replacements can be made to some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
