The outer wall of the first transverse axis (33) is fixedly sleeved with a spiral stirring blade (35). A plurality of second transverse axes (36) are fixed horizontally at a circular shape and uniformly spaced below the outer wall of the stirring shaft (32). A rotating plate (37) is fixed to the outer end of the second transverse axis (36). A discharge pipe (38) is installed at the bottom of the inner cavity of the annular guide groove (31) through an electric gate valve.

6. The variable mixing and beating device for preparing tunnel cement slurry according to claim 1, characterized in that: A pair of third electric latches (12) are fixed symmetrically and invertedly on both sides of the bottom of the orifice plate (11) with respect to the spline shaft spline sleeve assembly (10); a circular plate (13) is connected between the lock tongues of the two third electric latches (12) via a clamping block and a circular clamping groove; the circular plate (13) is rotatably mounted on the outer wall of the spline sleeve of the spline shaft spline sleeve assembly (10); a pair of fourth electric latches (14) are fixed symmetrically and laterally with respect to the side wall of the support plate with respect to the second transmission shaft (9); the lock tongues of the fourth electric latches (14) are connected to the conical friction wheel of the conical friction wheel pair (15) located on the second transmission shaft (9) via the clamping block and the circular clamping groove; the conical friction wheel is slidably clamped to the square rod integrally connected to the second transmission shaft (9) via the square hole.
