Turbine rotor structure and grinding machine

The invention belongs to the technical field of grinding machines, and particularly relates to a turbine rotor structure and a grinding machine. The first turbine comprises a first fixing plate. A plurality of groups of guide blocks are clamped on the side wall of the first fixing plate; a sliding groove is formed in the guide block; a set of fixing rods are fixedly connected into the sliding groove, and the ends, away from the end fixedly connected with the sliding groove, of the fixing rods are located outside the guide block. A mounting groove is formed in the guide block; a locking mechanism is installed in the first fixing plate. When materials are ground, the materials firstly pass through a first turbine, when the materials are ground for the first time, the size of the materials is too large, a guide block needs to be replaced, an existing turbine rotor structure is integrated, the guide block cannot be replaced, and only the whole turbine rotor can be replaced, so that the size of the turbine rotor i
