Description

[Detailed description of the invention] The present invention relates to a support device for a screw conveyor used for both filling and discharging in a rotary disk type koji making device, and is particularly characterized in that the back frame of the screw conveyor is attached to the screw shaft side. That is.

Conventionally, the frame that was located on the back side of the screw conveyor and that enabled the loading and discharging of koji was a telescopic rod attached to a leg-shaped support 1 fixed to the ceiling of the koji making device, as shown in Figure 3. 2 via a bracket 3 so as to be movable up and down in accordance with the up and down movement of the screw conveyor 4. Figure 3 is a side view;
In the figure, reference numeral 5 is the dorsal frame. With such a structure, since the structure hangs down inside the koji making chamber, it becomes a nuisance and causes the propagation of various bacteria, and furthermore, production becomes complicated.

The present invention simplifies the structure described above and solves the conventional difficulties.Instead of the hanging structure in the koji making chamber, the screw shaft is made into a double shaft with a bearing pipe extrapolated, and the bearing pipe is replaced with a double shaft. It is unique in that it is fixed to a vertically movable support frame and that its bearing pipe supports the back frame.

FIG. 1 is a partial vertical cross-sectional view of a rotary disk type koji making apparatus equipped with a screw conveyor support device of the present invention, and FIG. 2 is an enlarged vertical cross-sectional view of the main part of the apparatus.
As seen in these figures, when the support device of the present invention is employed, there is no support or the like in the koji making chamber 6, unlike in the case of conventional support devices.

The screw conveyor 4 is attached to a screw shaft 8 extending in and out of the koji making chamber wall 7.
As is clear from Fig. 2, the bearing pipe 9
is inserted externally, and the back frame 5 is attached to one end of the bearing pipe 9. The screw shaft 8 is provided with a sprocket 10 at its tip and is connected to a motor 12 on a vertical movement support frame 25 by a chain 11, allowing the screw conveyor 4 to rotate.

Bearing pipe 9 to which the back frame 5 is attached
is fixed to a bearing bracket 15 attached to a vertically movable support frame 25 that supports a vertically movable screw receiver 14 screwed into a vertically disposed vertically movable screw 13. Therefore, as the vertically movable screw 13 rotates, the vertically movable screw receiver 14 moves up and down, and the bearing pipe 9 and the back frame 5 move up and down accordingly. At this time, the screw conveyor 4 also has a screw shaft 8 supported in a bearing pipe 9 by bearings 16, 16 at both ends thereof, and a motor 12.
Since it is integrated with the vertically movable screw receiver 14 by the vertically movable support frame 25, it moves up and down in the same way as the back frame 5 moves up and down.

In the koji making apparatus illustrated in FIG. 1, the screw conveyor 4 and back frame 5 on the inner cylinder 17 side of the koji making chamber are also moved up and down within the inner cylinder 17 at the same level as the koji discharge port 18 side. A vertically movable screw 19 is vertically provided in the koji discharge port 18, and this is configured to rotate in the same manner as the vertically movable screw 13 on the koji discharge port 18 side by means of a transmission 20, a shaft 21, and a motor-side transmission 22. Then, a vertically movable screw receiver 23 is screwed into this vertically movable screw 19, an arm-shaped bracket 24 is provided on the vertically movable screw receiver 23, and the back frame 5 is attached to this, and one end of the screw conveyor 4 is pivotally supported. ing. However, as another example, the shaft support structure on the inner cylinder side can be made into a double structure of an externally inserted bearing pipe similar to that on the koji discharge port side, so that it can move up and down in the same way.

If the screw shaft 8 is made into a double structure with a bearing pipe 9 equipped with a bearing and a back frame is attached to the bearing pipe as in the present invention, the supporting device is simplified and manufacturing costs are reduced. The structure inside the koji making chamber is simplified and does not get in the way, and it also prevents the proliferation of various bacteria. As a result, it also helps improve the quality of the koji-made products.
