2. Description of the Related Art Conventionally, in such a grain dryer, an outer casing is provided for each of a plurality of hot air supply units, and a heating means and a blowing means are provided inside each outer casing. Then, in order to allow intake from the intake ports located between the adjacent hot air supply units, a plurality of hot air supply units are juxtaposed in a state of being spaced from each other,
Corresponding to the hot air supply units that are arranged side by side with a space therebetween, the plurality of drying units are also arranged side by side with a space therebetween.

[0003]

However, when inspecting the heating means or the air blowing means of the hot air supply section, the inspection is carried out by entering the inside of the outer casing.
Since the outer casings are separately provided for the plurality of hot air supply units, it is necessary to enter the respective outer casings for inspection, and there is a problem that the workability of the inspection work is poor. Further, since a plurality of drying units are arranged side by side with a space therebetween, and a plurality of hot air supply units are also arranged side by side with a space therebetween, there is a problem that the installation area becomes large.

The present invention has been made in view of the above circumstances, and an object thereof is to improve the workability of inspection work and reduce the installation area.

[0005]

The grain dryer according to the present invention is characterized in that the plurality of drying sections are juxtaposed in close contact with each other, and the outer casing is provided with the heating of each of the plurality of hot air supply sections. Means and the blower means are integrally formed in a state of being internally provided, and a floor portion is provided that partitions the inside of the exterior casing into upper and lower chambers, and the heating means of each of the plurality of hot air supply portions is the floor portion. It is provided in the upper chamber in a state of being mounted on the above, and the air blowing means of each of the plurality of hot air supply units is provided in the lower chamber.

[0006]

According to the above characteristic structure, the outer casing is integrally formed in a state in which the heating means and the air blowing means of each of the plurality of hot air supplying portions are internally provided, so that the heating means and the air blowing means of the hot air supplying portion are formed. When inspecting, enter the integrally formed outer casing and inspect the blowing means of all hot air supply units in the lower chamber and the heating means of all hot air supply units in the upper chamber. be able to.

Further, as in the conventional case, the planar shape of the integrally formed outer casing is such that a plurality of outer casings are provided for each of the plurality of hot air supply units, and the plurality of hot air supply units are juxtaposed with each other at intervals. In the juxtaposed plane shape in this case, at least a portion corresponding to the interval provided between the adjacent hot air supply units can be removed. or,
As a result, the plurality of drying units can be juxtaposed in a state of being in close contact with each other.

[0008]

As a result, the workability of the inspection work can be improved and the installation area can be reduced.
