Description

Technical Field

[0001] The utility model belongs to the technical field of grain seed ventilation bins, in particular to a grain seed ventilation bin. Background Art

[0002] Grains such as wheat, rice and other cereals are mostly stored in granaries, which can achieve large-scale storage of grains through relatively sealed granaries.

[0003] Since grains are living seeds, they generate a lot of heat and moisture during storage due to their biological respiration. Therefore, in the actual storage process, when grains are piled up and stored in a granary, the granary needs to be ventilated to remove moisture and heat from the grains.

[0004] However, in the actual working process, due to the large amount of grains piled up in the granary, especially the seeds that have not been completely and fully dried, the piled seeds generate a lot of heat and moisture during the storage process, which makes the grain seeds easy to mold during the storage process. The mildew directly leads to the rot of the grain seeds. In severe cases, a large amount of grain in the granary will become moldy.

[0005] The specific reason is that during the storage process, a large amount of grain seeds are piled up in the granary, and during the ventilation process, the airflow cannot effectively pass through the grain pile to remove the heat and moisture inside the grain pile. After ventilation, only the moisture and heat at the upper level of the grain pile can be effectively removed.

[0006] Therefore, in the actual grain storage process, especially when the grain seeds are not completely dried and the weather is hot and humid such as the rainy season, the seeds in the granary will mold very quickly. After the grain seed pile is opened, the heat and humidity inside the grain pile are very high, the moldy degree is relatively serious, and the musty smell is relatively strong, causing serious economic losses.

[0007] Obviously, the ventilation structure in the existing granary can only meet the storage needs of fully dried grains. However, in the actual production process, a large amount of newly harvested grains (not fully dried) need to be stored in the silo. During the storage process, it is crucial to keep the grain inside the grain pile dry and not moldy. Utility Model Content

[0008] Based on the above background, the purpose of the utility model is to provide a grain ventilation bin.

[0009] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0010] A grain ventilation bin comprises a ventilation bin body, wherein the ventilation bin body is a conventional grain storage bin disclosed in the prior art, and a ventilation hole is opened on the top thereof, and a fan is installed in the ventilation hole.

[0021] Preferably, the bottom of the vertical pipe is connected to the bottom horizontal pipe seat through a short connecting pipe.

[0022] Preferably, the ventilation elbow assemblies are pulled together via a plurality of pulling connectors.

[0023] Preferably, the pulling connection member comprises pulling rods respectively fixedly connected to the top positions of the vertical tubes on both sides, and a connecting screw is threadedly connected to the pulling rod on one side;

[0043] Example 1

[0044] like Figure 1-6 As shown, a grain ventilation bin includes a ventilation bin body 1. The ventilation bin body 1 is a conventional grain storage bin disclosed in the prior art, and a ventilation hole 31 is opened on the top thereof. A fan 3 is installed in the ventilation hole. During the grain storage process, the fan 3 is used to realize the airflow exchange inside and outside the ventilation bin body 1.

[0045] The ventilation bin body 1 is equipped with a ventilation mechanism 2 located in the grain pile; the ventilation inside the grain pile is achieved through the ventilation mechanism 2. Specifically, after the grains are piled up, especially the grains with small particles such as millet, it is difficult for the airflow in the grain pile to pass through and enter, making it difficult to remove the heat and humidity in the grains.

[0046] The ventilation mechanism 2 includes a ventilation main pipe 22 (during the construction process, the ventilation main pipe 22 is arranged outside the granary), and the ventilation main pipe 22 is connected to a plurality of ventilation elbow assemblies.

[0047] Specifically, a plurality of ventilation elbow assemblies are buried in the grain pile to remove heat and moisture from the grain pile.

[0048] Specifically, the ventilation elbow assembly includes a bottom horizontal pipe seat 21 arranged on both sides (according to the existing method, a sinking trough is opened on the foundation inside the ventilation bin body 1, and the bottom horizontal pipe seat 21 is installed in the sinking trough. When passing through, the upper trough cover is installed at the top position of the sinking trough), the bottom horizontal pipe seat 21 is connected to the ventilation main pipe 22, and a number of ventilation elbow components 23 are connected between the bottom horizontal pipe seats 21. In this way, the bottom horizontal pipe seat 21 is prevented from being compressed and deformed. The bottom horizontal pipe seat 21 is a stainless steel pipe, and the main structure is a rectangular parallelepiped. It is not easy to shake when installed in a rectangular parallelepiped sinking trough.

[0049] The above-mentioned ventilation elbow component 23 includes vertical pipes 232 which are respectively connected vertically to the top position of the bottom horizontal pipe seat 21 (the bottom of the vertical pipe 232 is connected to the bottom horizontal pipe seat 21 through a short connecting pipe), and the vertical pipes 232 are connected by a plurality of ventilation elbows 231 which are arranged at intervals above and below and buried in the grain pile; a plurality of exhaust holes 2311 are opened on the ventilation elbow 231; the ventilation elbow 231 has different directions on the vertical plane.

[0050] Specifically, the ventilation elbow 231 is serpentine in shape, and the main structure includes: a plurality of upper arc-shaped parts and lower arc-shaped parts that are integrally formed in sequence; and the exhaust holes 2311 are located on the upper arc-shaped parts and the lower arc-shaped parts.

[0051] The advantage of adopting this shape design is that: in the grain pile, the serpentine movement increases the radiation range of the ventilation elbow 231 in contact with the grain pile. Specifically, the upper arc portion and the lower arc portion have a larger contact area with the grain pile compared to the straight structure design.

[0052] At the same time, in order to increase the ventilation radiation range, different ventilation elbows 231 are designed to have different orientations, so that the ventilation airflow discharged from the ventilation elbows 231 moves in different directions, thereby increasing the ventilation effect area.

[0053] Specifically, the vertical pipes 232 are connected with an upper ventilation elbow, a lower ventilation elbow, and a middle ventilation elbow located between the upper ventilation elbow and the lower ventilation elbow; the upper ventilation elbow is tilted to the left (30 degrees on the left), and the lower ventilation elbow (30 degrees on the right) and the middle ventilation elbow are tilted to the right (60 degrees on the right). In this way, after the airflow is discharged from the upper ventilation elbow, the lower ventilation elbow, and the middle ventilation elbow, the airflow flows in different directions inside the grain pile from different positions, thereby achieving full ventilation inside the grain pile. The moisture and heat inside the grain pile are fully carried and discharged from the top surface of the grain pile.

[0054] The ventilation main pipe 22 is connected to the bottom horizontal pipe seat 21 through a plurality of branched connecting pipes 221. According to the conventional method, the ventilation main pipe 22 is connected to a pump air main pipe, which is connected to the blower. During operation, the blower works to pump the air flow into each upper ventilation elbow, lower ventilation elbow and middle ventilation elbow in a split manner, and removes heat and moisture from the grain pile in the above manner.

[0055] Example 2

[0056] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, the ventilation elbow components are pulled together through a plurality of pulling connectors.

[0057] Specifically, the adjacent ventilation elbow components are connected as one by pulling the connecting piece. The pulling has the advantages of improving stability during the material discharge and storage process and preventing the grain from pushing, squeezing and overwhelming the ventilation elbow components.

[0058] Specifically, the pulling connection member includes pulling rods 233 respectively fixedly connected to the top positions of the vertical tubes 232 on both sides, a connecting screw 2331 is threadedly connected on one side of the pulling rod 233, and a threaded connection groove is opened on the other side of the pulling rod 233.

[0059] The pulling rod 233-threaded connection groove structure on the right side of the left ventilation elbow assembly is connected to the pulling rod 233-connecting screw 2331 on the left side of the right ventilation elbow assembly, that is, the connecting screw 2331 is screwed into the threaded connection groove to connect all the ventilation elbow assemblies in series in sequence.

[0060] The above method can greatly improve the stability of the ventilation elbow assembly buried in the grain pile.

[0061] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
