Is driven to rotate with the length of the radius of rotation as the radius of gyration.

Further, since the crank pin 21b rotates concentrically as the crank shaft 21 rotates due to the rotation of the crank shaft 21, only the vertical movement of the crank pin 21 is supported by the guide shaft 35 and the guide body 36. The elevating frame 14 that is restricted so that it cannot be moved up and down with a stroke that is twice the length of the crank arm 21a.

As a combined motion of the rotary motion and the vertical motion, the locus 42 of the pivot shaft 10 at the lower end of the main arm 9 is shown in FIG.
It becomes an ellipse with a long axis in the vertical direction as shown in. Therefore, the stirring plate 8 pivotally supported on the lower end of the main arm 9 by the pivot 10 also makes an elliptical motion in the ball 2.

At this time, the stirring plate 8 is turned downward by the operation of the air cylinder 38 of the stirring plate scooping drive mechanism 13 as shown in FIGS. 1 and 4 when the main arm 9 is descending.

It is possible to prevent the object to be agitated at the center of the bottom of the ball 2 from being left without being agitated even when the ball 2 is moved in an elliptical manner.

As the agitating operation of the agitating plate 8 as described above is performed for about one cycle, the ball 2 is gradually rotated around the axis 3 by the rotation of the motor 7 of the ball rotating mechanism 4 and the ball 2 is rotated. The scraping position of the agitated object inside is changed in the circumferential direction. Therefore, the objects to be stirred in the ball 2 can be mixed uniformly over the entire circumference. For this reason, by stirring up the stirring plate 8 similar to a finger, the objects to be stirred can be well mixed and mixed, so that the objects to be stirred are, for example, a mixture of foamed eggs, sugar, etc., and flour. In some cases, it is possible to produce fine-grained soft dough without powder lumps.

The crankshaft 21 has V pulleys 23, V
Alternatively, the belt 24 and the V pulley 25 may be omitted and the crankshaft drive motor 26 may directly drive the crankshaft drive motor 26. The crankshaft 21 may be a simple drive shaft, and the main arm lifting mechanism 16 may be a fluid pressure cylinder such as an air cylinder.
