As a result, without increasing the installation space,
In addition, it is possible to increase the storage capacity of the storage bin without increasing the height of the building.

[0007] The above technical means include installing a new storage bin provided with an additional storage section and improving the storage bin by connecting the additional storage section to an existing storage bin having a square cross section. It is a thing.

[0008] As the above-mentioned technical means, for example, a storage bin aggregate is formed by arranging a plurality of powdery material storage bins having a rectangular cross section arranged in three rows, and a central row of the storage bin aggregate is formed. In the storage bin assembly of the above, if an additional storage portion having a cross-sectionally funnel-shaped shape is provided in the space above the storage bin assembly other than the center row, the storage bin having a square cross-section is connected in two stages, and the side plate , The structure of the storage bin assembly is stabilized.

The storage bin having a rectangular cross section has a floor structure having a large number of ventilation holes through which drying air can be supplied from below the storage bin, and the drying air is exhausted from above the storage bin. With such a structure, for example, a storage bin for temporarily drying received grains and a storage bin for storing primary dried grains can be used.

[0010] Further, since a stirring auger capable of stirring the lower layer powder and the upper layer powder and granule is provided in the powder and particle storage bin having no additional storage section, for example, in the storage bin, Among the thickly deposited cereals, the lower cereal grains and the upper cereal grains are agitated so that the cereals do not deteriorate.
