Double-geared roller crusher

The utility model relates to a double-geared roller crusher comprising a movable bearing seat, a fixed bearing seat, a spring safety device, a fixed tooth roller, a movable tooth roller and driving devices, wherein the movable tooth roller is arranged on the movable bearing seat, the fixed tooth roller is arranged on the fixed bearing seat, the movable bearing seat moves on the rail of an engine base, one end of the spring safety device leans on the movable bearing seat, the movable tooth roller is driven by a first driving device, and the fixed tooth roller is driven by a second driving device. The double-geared roller crusher has the advantages that the two tooth rollers of the equipment are respectively driven by different motors to achieve differential operation of the two tooth rollers, in order to crush materials more quickly and prevent easy material blockage. Each driving device inputs power in such a manner that the motor, an elastic pin coupling and a speed reducer are directly connected, so the energy consumption is greatly reduced. Since both of the motor and the speed reducer are standard equipment, in the case of failure, the motor and the speed reducer can be changed singly and very conveniently, so that the maintenance cost is low.
