[0007]

However, in the conventional fermentation drying processing apparatus described above, the rotating frame 1 is provided in addition to the rails 110 for running the carriage 120.
Since a circular rail 130 for turning the 40 is required, and the circular rail 130 needs to be mounted on the carriage 120, the structure of the apparatus becomes complicated and
There is a problem that the whole apparatus becomes bulky, and it is difficult to achieve simplification and downsizing of the apparatus, and that the roof height of the processing building has to be increased.

Further, in a conventional fermentation drying treatment apparatus,
Since it was necessary to make the width of the fermenter 100 equal to the width of the carriage 120 and the rotating frame 140, it was difficult to increase the width of the fermenter 100 and increase its capacity, thereby increasing the processing efficiency. there were.

Further, in order for the stirring device 150 to efficiently switch back the processed material, the moving stirring device needs to be oriented in the traveling direction of the carriage 120. Therefore, the stop position when the rotating frame 140 turns is determined. There is a problem that accurate control is required, which has led to an increase in the complexity of the apparatus.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and the stirrer can be mounted on a truck so that the stirrer can be simplified and downsized. It is an object of the present invention to provide a fermentation drying treatment apparatus which enables the height of the apparatus to be reduced and does not require the roof height of the treatment building to be so high.

It is another object of the present invention to provide a fermentation drying apparatus capable of increasing the width of the fermenter and doubling the capacity of the fermenter by providing a center rail.

It is a further object of the present invention to provide a fermentation drying apparatus which does not require the use of a special control member to control the direction of the stirring device.

[0013]

According to the present invention, there is provided a fermentation drying apparatus comprising a center rail, a pair of side rails arranged in parallel with the center rail and arranged on both sides thereof, and a pair of side rails. An endless traveling path is formed by a pair of arc-shaped turn rails connecting one end of the section and the other end of the section, and a bogie traveling along the endless traveling path is stored in the fermenter. Rolls the stirrer and the center rail of the processed material such as manure
Inner wheel, a pair of side rails and a pair of turn rails
Drive the outer wheels that roll the
And an electric motor for turning the inner wheel
While being rotatably mounted on the trolley,
In two places of the tarrail part, the rolling of the inner wheel is
The vertical axis of each of the pair of arc-shaped turn rails
A mechanism for positioning each at the center position is provided.
-These mechanisms provided at two places on the rail
It is a wheel stopper protrudingly provided on the tar rail portion .

With this configuration, when the truck travels on the endless traveling route, the agitator also moves on the endless traveling route together with the truck. Therefore, when the stirrer is fixedly mounted on the carriage in the traveling direction, the processed material can be efficiently stirred without controlling the direction of the stirrer using a special control member. In addition, there is no need to adopt a complicated configuration in which a rotating frame with a stirrer is mounted on a circular rail provided on a trolley as in the conventional device, which simplifies and downsizes the device. At the same time, the height of the processing building is not required because the apparatus becomes shorter. In addition, since the endless traveling path of the bogie is formed separately by the center rail portion and a pair of side rail portions on both sides thereof, the width of the fermentation tank should be about twice as large as the width of the bogie. And the capacity of the fermenter can be doubled.

Further, when the bogie is traveling on an endless traveling route, the inner wheels of the bogie are positioned on the center rail positioning mechanism.
When the rolling is stopped by hitting the wheel stopper that forms, the vertical axis corresponding to the rotation axis when the inner wheel rotates relative to the bogie at the time when the rolling is stopped is an arc-shaped turn rail. Coincides with the center position of the part. Therefore, while the rolling of the inner wheel is prevented by the positioning mechanism, the outer wheel rolls on the turn rail portion while the inner wheel of the bogie stops at that position, so that the bogie is endless. The operation of changing the direction along the traveling route and entering the return path from the outward path or the operation of entering the return path from the return path is performed naturally without any control.

In the fermentation drying treatment apparatus having the above-mentioned configuration, a stirring apparatus of a type in which the processed material stored in the fermentation tank is scraped up and cut back to the rear thereof can be adopted.

When such a stirring device is employed,
By continuously operating the fermentation drying processing apparatus and causing the bogie to travel in one direction on the endless traveling path, the processed material in the fermentation tank is sequentially fed backward in the running direction of the bogie, and the processed material is separated into upper and lower layers. The operations required for fermentation and drying, such as replacement between the two, are performed continuously.
