Description

Detailed Description of the Invention

[0001]

[Industrial field of application] The present invention is mainly intended for wheat and other grains, and is for joint grain drying such as a rice center, a country elevator, and a dry store, which is composed of a receiving section, a drying section, a storage section, a preparation and shipping section, and the like. It relates to a drying device for voluntary inspections at facilities.

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Publication No. Sho 58-145493, a lot of sample paddy is placed in each of a plurality of drying containers installed in a drying chamber, and after a certain period of time, the lot of sample paddy is removed from the drying container. There is a technology to take it out.

[0003]

In the prior art, since a plurality of drying containers are mounted on a conveyor and circulated in a drying chamber, a space other than the storage of sample grains, for example, a space for installing a conveyor or an empty container moving space. Is formed in the drying chamber, the number of drying vessels installed is likely to be limited, and it is necessary to expand the drying chamber to add more drying vessels,
There is a problem that the structure of the inside of the drying chamber cannot be easily simplified by installing a conveyor or the like, and the workability such as cleaning or maintenance of the drying chamber cannot be easily improved.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is a drying apparatus for a voluntary inspection in which a plurality of drying containers containing sample grains are installed in a drying chamber, and the drying containers are arranged in parallel in the drying chamber. A loading member for loading the sample grains of the receiving hopper into each drying container is movably attached to each drying container installation position, and a moving member for moving the loading member in the parallel direction of each drying container is provided. By arranging them side by side, the installation space of the drying container containing the sample grains can be expanded more easily than before by effectively using the drying chamber, and it is possible to add more drying containers than before without increasing the volume of the drying chamber. In addition to being easy to carry out, the conventional conveyor that circulates and moves the drying container can be omitted, which simplifies the internal structure of the drying chamber and improves workability such as cleaning and inspection of the drying chamber. It is those that can be done to.
