Description

Technical Field

[0001] The utility model relates to the technical field of grain drying, in particular to a static drying and storage integrated machine. Background Art

[0002] After harvesting, grain is often dried in fields or on the road before being stored. However, this method cannot guarantee the quality of the grain drying, and there is also a shortage of drying space. Existing grain dryers are used to dry grain, which are less affected by weather and the site, while also shortening the drying time. However, existing grain dryers cannot store grain, requiring manual transport of the dried grain to storage. When grain is stored for too long, the grain at the bottom of the storage silo can easily deteriorate and mold. Summary of the Invention

[0003] In order to solve the problems that the existing dryers cannot store grain and the grain at the bottom of the grain storage bin is easily deteriorated and moldy after being piled up for too long, the utility model provides a static drying and storage integrated machine, which realizes the drying function of the grain storage bin through the arrangement of a hot air blower, a centrifugal fan, a grain storage bin, a first air duct and a second air duct. The arrangement of the second air duct realizes the drying of the grain at the bottom of the grain storage bin, thereby preventing the grain at the bottom of the grain storage bin from deteriorating and becoming moldy.

[0004] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0005] A static drying and storage machine includes a hot air blower and a grain storage bin, wherein the hot air blower is further connected to a centrifugal fan, and a ventilation hole is opened on the side wall of the grain storage bin; an air supply pipe is provided between the grain storage bin and the hot air blower, wherein one end of the air supply pipe is connected to the hot air blower and the other end passes through the grain storage bin and is provided inside the grain storage bin;

[0006] A first air duct and a second air duct are provided inside the grain storage bin. The first air duct is provided at the upper part of the grain storage bin and is connected to the air supply pipe. The second air duct is provided at the bottom of the grain storage bin and is connected to the air supply pipe. Both the first air duct and the second air duct are provided with air dispersion holes.

[0007] Furthermore, the grain storage bin is a rectangular enclosure formed by a plurality of perforated plates, and the plurality of ventilation holes are evenly distributed on the four walls of the grain storage bin, so as to facilitate ventilation and moisture removal, and prevent the grain from being unable to dissipate heat inside the grain storage bin during storage, causing the grain to deteriorate.

[0008] Furthermore, the grain storage bin is a rectangular structure with an open top and a closed bottom.

[0009] Furthermore, the apertures of the ventilation holes and the air dispersion holes are both in the range of 2-12 mm, and are smaller than the particle size of the stored grains, to prevent grains from scattering from the ventilation holes of the grain storage bin and affecting the storage effect.

[0010] Furthermore, the first air duct includes two groups, each group including a connecting pipe and at least one air duct. The connecting pipe is vertically fixed to the upper portion of the air supply pipe and is connected to the air supply pipe. One end of the air duct is closed and the other end is connected to the connecting pipe. The first air duct is provided with four air ducts to improve the drying effect and shorten the drying time.

[0011] Furthermore, each group of the first air ducts includes a plurality of air ducts, and the plurality of air ducts are arranged along the length direction of the connecting pipe.

[0012] Furthermore, the second air duct is a rectangular channel with an open bottom, and the connecting end between the second air duct and the air supply pipe is a solid plate.

[0013] Furthermore, a plurality of brackets are arranged between the plurality of air ducts, the brackets being arranged along the length direction of the air ducts and connected to the adjacent side walls of the grain storage bin to prevent the first air duct from deforming.

[0014] Furthermore, support rods are provided at the top and bottom of the grain storage bin and the bottom of the second air duct to prevent the grain storage bin and the second air duct from deforming and improve structural stability.

[0015] Furthermore, a cover is sleeved on the upper part of the grain storage bin, and a plurality of ventilation holes are provided on the side wall and the top of the cover to prevent foreign objects from entering the grain during storage.

[0016] Through the above technical solution, the beneficial effects of the utility model are:

[0017] The utility model realizes the two functions of storing grain and drying grain by arranging a centrifugal fan, a hot air blower, a grain storage bin, a first air duct and a second air duct. The utility model realizes rapid drying of grain by arranging the first air duct and the second air duct. The utility model realizes drying of the bottom of the grain storage bin by arranging the second air duct, thereby preventing grain from being easily deteriorated and moldy due to accumulation at the bottom of the grain storage bin for too long. The utility model has multiple ventilation holes on the four walls of the grain storage bin for easy ventilation and moisture removal, thereby preventing the grain from being unable to dissipate heat inside the grain storage bin during storage, thereby causing the grain to deteriorate. Support rods are arranged between the bottom and the top of the grain storage bin and between the bottom of the second air duct and the air duct of the first air duct, thereby preventing excessive deformation of accumulated grain and improving structural stability.

[0027] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings:

[0028] Example 1: Figures 1 to 6 As shown, a static drying and storage machine includes a hot air blower 2 and a grain storage bin 4. The hot air blower 2 is also connected to a centrifugal fan 1. The grain storage bin 4 is a rectangular fence surrounded by multiple perforated plates. Multiple ventilation holes are opened on the four walls of the grain storage bin 4. The multiple ventilation holes are evenly distributed on the four walls of the grain storage bin 4, which facilitates ventilation and moisture removal, and prevents the grain from being unable to dissipate heat inside the grain storage bin 4 during the storage stage, causing the grain to deteriorate.

[0029] To optimize product structure and prevent grain poured into the grain storage bin 4 from scattering through the ventilation holes during the drying and storage stages, which would affect storage efficiency, the ventilation holes have a diameter range of 2 to 12 mm. Due to the varying grain sizes, when storing larger grains such as peanuts, the ventilation hole diameter is 10 mm. When storing smaller grains, the ventilation hole diameter is correspondingly smaller.

[0030] An air supply pipe 3 is arranged between the grain storage bin 4 and the hot air blower 2. One end of the air supply pipe 3 is connected to the hot air blower 2, and the other end passes through the grain storage bin 4 and is arranged inside the grain storage bin 4. The air supply pipe 3 arranged inside the grain storage bin 4 is a trapezoidal structure.

[0031] A first air duct and a second air duct 6 are provided in the grain storage bin 4, and the first air duct includes two groups, and each group of the first air duct includes multiple air ducts 5 and connecting pipes 8, and the connecting pipes 8 are vertically fixed to the upper part of the air supply pipe 3, and the connecting pipes 8 are connected to the air supply pipe 3; in this embodiment, there are two air ducts 5, and the two air ducts 5 are arranged in the middle and upper part of the grain storage bin 4, and one end of each air duct 5 is closed and the other end is connected to the connecting pipe 8.

[0032] The first air ducts are divided into two groups, each group of which includes an air duct 5 and a connecting pipe 8. The connecting pipe 8 is vertically fixed to the top of the air supply pipe 3 and communicates with the air supply pipe 3. The air duct 5 is a pipe structure with one end closed and the other end open, and the open end of the air duct 5 is connected to the connecting pipe 8. The first air duct includes four air ducts 5, which are respectively arranged in the middle and upper parts of the grain storage bin 4 to improve the drying effect and shorten the drying time.

[0033] To improve the stability of the air duct 5, multiple brackets 9 are set between the two groups of first air ducts. In this embodiment, there are two brackets 9, which are respectively set in the middle and closed end of the air duct 5. The brackets 9 are in an "open" shape. The two air ducts 5 set in the upper part of the grain storage bin 4 are set on the top of the brackets 9, and the two air ducts 5 set in the lower part of the grain storage bin 4 are set in the gap at both ends of the brackets 9. This prevents the air duct 5 from deforming when transporting grain.

[0034] The second air duct 6 is disposed at the bottom of the grain storage bin 4. This second air duct 6 is an open-bottomed rectangular channel with multiple air dispersion holes on its top and sidewalls. The second air duct 6 is connected to the bottom of the air supply pipe 3, and the connection between the second air duct 6 and the air supply pipe 3 is a solid plate. Both the first and second air ducts 6 are provided with air dispersion holes. To prevent grain from escaping into the first and second air ducts 6 and affecting the air supply efficiency, the apertures of the air dispersion holes range from 2 to 12 mm. The diameter of the air dispersion holes varies depending on the grain size. In this embodiment, when storing larger grains such as peanuts, the aperture of the air dispersion holes is 10 mm. When storing smaller grains, the aperture of the air dispersion holes is correspondingly smaller, i.e., the aperture of the air dispersion holes is smaller than the average diameter of a single grain particle. The provision of the second air duct 6 dries the bottom of the grain storage bin 4, preventing grain from accumulating at the bottom of the bin 4 for an extended period of time, which can lead to spoilage and mold.

[0035] In order to prevent the grain storage bin 4 from being deformed due to excessive grain accumulation, support rods 7 are provided on the top and bottom of the grain storage bin 4 and the bottom of the second air duct 6 to improve the structural stability.

[0036] When in use, select a suitable grain storage bin 4 and air duct 5. For example, if you need to dry peanuts, choose a grain storage bin 4 and air duct 5 with ventilation holes and air dispersion holes with an aperture of 10mm. Pour the grain into the grain storage bin 4, so that the grain falls between the upper part of the second air duct 6 and the first air duct. Then start the centrifugal fan 1 and the hot air blower 2. The centrifugal fan 1 transmits hot air through the air supply duct 3 to the first and second air ducts 6. The air duct 5 of the first air duct dries the grain in the middle and upper parts of the grain storage bin 4, and the second air duct 6 dries the grain at the bottom of the grain storage bin 4. The ventilation holes on the four walls of the grain storage bin 4 dissipate moisture from the grain. The dried grain is directly stored in the grain storage bin 4, without the need for secondary handling. If the grain has been stored for too long, the centrifugal fan 1 and hot air blower 2 can be directly started for secondary drying.

[0037] Example 2: Figure 7-Figure 8 As shown, the structure of the second embodiment is basically the same as that of the first embodiment, and the similarities are not repeated here. The difference is that the grain storage bin 4 is a rectangular structure with an open top and a closed bottom. A cover 10 is fitted over the upper portion of the grain storage bin 4, and a plurality of ventilation holes are provided on the sidewalls and the top of the cover 10 to prevent foreign objects from entering the grain during storage.

[0038] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
