The stirring drive shaft (28) of the present invention is driven by the drive motor (3) housed in the cave (30) as described above.
1) which is driven from 1) and which meshes with the small gear (33) of the drive shaft (32) of the intermediate shaft (34).
5) is driven by the drive motor (31), and the intermediate shaft (3
The small sprocket (36) of 4) drives the large sprocket (38) via the chain (37) to drive the stirring claw shaft (28). Therefore drive motor (31)
Therefore, the stirring claw shaft (28) is driven by a two-speed shift, and a high reduction ratio can be obtained. Moreover, since the stirring claw shaft (28) and the intermediate claw shaft (34) use the chain (37), the load fluctuation of the stirring claw shaft (28) is transmitted to the motor (31) and the gears (33) (35). Since it is not present, damage to the motor and gear can be prevented. It should be noted that the driven gear (35) and the reduction sprocket (36) are integrated and are idled on the intermediate shaft (34). This integration involves tightly fitting the boss of the reduction sprocket (36) to the driven gear (35) or a key,
It can be properly integrated by spline fitting.
