The protrusions 10 are an even number, and the specific number of the protrusions 10 is six. There is an arc transition between the protrusions 10 and the outer peripheral wall of the fixed plate 9, and the upper end of the swing arm 801 abuts against the outer peripheral wall of the fixed plate 9; A sphere 804 is fixedly disposed on the upper end of the swing arm 801; The extrusion plate 803 is provided with a through hole 805, and the crushed agglomerates pass through the through hole 805; During operation, the stirring blade 7 rotates while driving the swing arm 801 to rotate synchronously, that is, driving the ball 804 connected to the swing arm 801 to rotate on the outer peripheral wall of the fixed plate 9, and through the elastic action of the elastic member 802, the swing arm 801 swings back and forth around the hinge point between the swing arm 801 and the stirring blade 7, and the end of the swing arm 801 reciprocates toward or away from the axis direction of the driving shaft 5. The reciprocating swing of the swing arm 801 increases the stirring angle of the raw materials and improves the stirring efficiency of the raw materials. Moreover, the swing directions of the two swing arms 801 are opposite. When the lower ends of the two swing arms 801 are close to each other, the two extrusion plates 803 are attached to each other, so that the lumps in the raw materials are squeezed and crushed, thereby improving the stirring effect of the raw materials, and the crushed lumps pass through the through hole 805; A conduit 11 is provided in the tank body 1, and the conduit 11 is coaxially arranged with the drive shaft 5.
