The invention discloses an anti- fracturingfracturing blade stirring device. The anti- fracturingfracturing blade stirring device comprises a main shaft, the top of the main shaft is connected with a shaft coupler, and the main shaft is detachably connected with a group of connecting plates; the connecting plates are detachably connected with a bearing chamber; the bearing chamber is in running fit with a stirring shaft through a bearing; a torsion spring fitted with the stirring shaft is arranged in the bearing chamber; one end of the stirring shaft is fitted with the bearing chamber through the torsion spring, and the other end of the stirring shaft is welded with a ground of stirring blades; one surface of each stirring blade is welded with a group of auxiliary ridges; the main shaft is a square column, four surfaces of the square column are detachably connected with the connecting plates. The anti-fracturing blade stirring device disclosed by the invention is flexible for detaching, stable and reliable in component fitting, high in strength, and good in impact resistance; when the big, heavy and hard blocks are existent in the stirred material, the stirring blades can passively produce the elastic rotation to buffer the impact force, the probability of damaging the stirring blade is lowered, the service of the device is prolonged, and meanwhile, the maintenance and replacement of the component are convenient.
