The utility model realizes the adjustment of rotor rotation direction and being transported from rising, from decline for slurry by rotor device for regulating direction It is dynamic, i.e., the tune of rotor A30 and the directions rotor B31 are realized by the horizontal bevel gear 29 of rotor device for regulating direction and vertical bevel gear 18 It is whole, and the rotor A30 after the adjustment of direction and rotor B31, slurry will be driven to realize the movement from rising or from declining when rotated, Specially when equipment works, kuppe 16 is opened, rotary turnplate 38 simultaneously drives horizontal bevel gear 29 to rotate, because of vertical bevel gear 18 and horizontal bevel gear 29 engage, vertical bevel gear 18 will drive shaft A26 rotation, because shaft A26 is equipped with belt wheel 21 and skin Band 25, belt 25 connects the belt wheel 21 on other shaft B24, and in this way under the drive of belt 25, shaft B24 and main shaft 3A will be real Existing synchronous rotary, and then realize the rotor A30 on shaft A26 and shaft B24 or the synchronous adjustment in the directions rotor B31；Turntable 38 Left and right rotation, rotor A30 and rotor B31 rotating Vortexes will be driven, such as when rotor A30 and rotor B31 rotations 45 counterclockwise Degree, by realize slurry from ascending motion, and rotor A30 and rotor B31 rotate clockwise 45 degree, will realize slurry from declining Movement.

The utility model realizes the fixation of turntable 38 by 2 fixed pins being symmetrically installed 20, and then passes through turntable 38 It is fixed, prevent the rotation of horizontal bevel gear 29, vertical bevel gear 18, shaft A26, shaft B24, rotor A30 and rotor B31.
