A stirring method for a sulfur foam stirring device according to claim 9, characterized in that: The following steps are involved: Step 1, closing the liquid discharge pipe (12), opening the liquid inlet pipe (11), pouring the sulfur foam liquid into the cylinder (1) through the liquid inlet pipe (11), and under the action of the air compressor (17), the compressed air enters the air distributor (14) through the annular pipe (16), and then is discharged through the air outlet (15), and the airflow formed by the discharge drives the sulfur foam liquid to rotate at a high speed; Step 2: Under the driving action of the servo motor (48), the motor shaft of the servo motor (48) drives a pair of fixed gears (46) to rotate in a forward and reverse direction, and under the limiting meshing action formed by the limiting pin shaft (47) and the limiting notch, the limiting plate (45), the linkage shaft (4), the linkage bevel gear (41), and the gear plate (44) are driven to rotate in a forward and reverse direction reciprocatingly; Step 3: The linkage bevel gear (41) meshes to drive the driven bevel gear (42) to rotate, and the driven pin shaft (43) on the driven bevel gear (42) and the second elliptical pin hole form a limiting effect, driving a pair of reciprocating swing arms (32) to swing back and forth along the connecting pin shaft (31); Step 4: The first elliptical pin holes on the pair of reciprocating swing arms (32) and the pair of fixed pin shafts (34) on the rectangular sleeve (33) form a limiting effect, driving the rectangular sleeve (33) and the T-shaped slider (36) to slide reciprocatingly along the slide rail bracket (35), thereby driving the I-shaped shaft (22), the center shaft (21), and the three-claw plate (24) to slide reciprocatingly along the fixed slide cylinder, and synchronously driving the planetary shaft (25), the swing arm connecting rod (27), the stirring shaft (28), and the stirring paddle (29) to move reciprocatingly; Step 5: The gear plate (44) meshes to drive the widened gear (23), the central shaft (21), and the three-claw plate (24) to rotate back and forth in both positive and negative directions. The planetary gear (26) on the planetary shaft (25) meshes and rotates along the widened outer gear ring (2), and drives the planetary shaft (25), the swing arm connecting rod (27), the stirring shaft (28), and the stirring paddle (29) to perform reciprocating planetary rotation. The stirring paddle (29) fully stirs the sulfur foam liquid, thereby achieving the purpose of fully mixing the sulfur foam liquid.
