Scraper driving device for preparing metal sodium

The utility model relates to the technical field of metal sodium electrolytic bath receivers, and particularly discloses a scraper driving device for preparing metal sodium. Comprising a motor, a first synchronous belt wheel, a second synchronous belt wheel, a synchronous belt, a spline shaft, a spline sleeve and an air cylinder, the spline shaft is vertically arranged at the position, corresponding to a scraper shaft, of a rack, the air cylinder is arranged on the rack and above the spline shaft, and the motor is detachably arranged on one side of the air cylinder and on the rack; the spline shaft is sleeved with a spline sleeve in a meshed mode, the spline sleeve is fixedly sleeved with a second synchronous belt wheel, and the first synchronous belt wheel and the second synchronous belt wheel are in meshed transmission through a synchronous belt. Gear transmission is replaced by synchronous belt and synchronous belt wheel transmission, so that installation and maintenance are more convenient, and compared w
