DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain drying apparatus for a country elevator or the like.

[0002]

2. Description of the Related Art Conventionally, for example, a plurality of main storage silos are arranged at predetermined intervals in two rows. Since these main storage silos are cylindrical, a space is formed between adjacent silos. In this space, a plurality of sub-storage silos are provided, and finish drying is performed while exchanging grains with a grain drying device that receives and dries grains preliminarily dried in each storage tank. (FIG. 5).

[0003]

The grains preliminarily dried in each of the storage tanks (a) are discharged from each of the storage tanks (a), a discharge conveyor (b), a grain raising machine (c), and a conveyor (d). It is supplied to each grain dryer (g) through a grain raising machine (e) and a drying conveyor (f), and is circulated and dried in each dryer (g).

[0004] The dried grains dried in the respective dryers (g) are passed from the respective dryers (g) through a grain raising machine (h) and a transfer device (i) or a transfer device (nu). And transferred to each main storage silo (ル) or (ヲ).
Further, each sub-storage silo (W) is provided with the discharge conveyor (B), the grain-raising machine (C), the conveyor (D), the grain-raising machine (E), and the drying conveyor from each of the storage tanks (A). After receiving the semi-dried paddy sent to the respective dryers (g) through (f), the refining is performed while exchanging with the dryers (g).

The grains in each of the main storage silos (サ イ) and (ヲ) and each of the sub-storage silos (ワ) are placed on a lower first discharge conveyor (f) or a second discharge conveyor (Y). And are transported by these first and second discharge conveyors (f) and (f) to be supplied to the working machine in the next step. In the above operation, the sub-storage silos (W), provided in the space between the main storage silos (貯), (サ イ), and the main storage silos (ヲ), (ヲ), (A) is abolished, and a grain drying device (ta) having the dryers (g), (g) is provided instead of the sub-storage silos (wa), (g). Thus, cost reduction and layout compactness are attempted.
