Novel mechanical scraper machine

The utility model relates to the technical field of metal sodium preparation, in particular to a novel mechanical scraper machine which comprises an upper base plate, a middle base plate and a lower base plate are sequentially arranged below the upper base plate, and four hexagonal studs are fixedly connected between the upper base plate and the middle base plate and between the middle base plate and the lower base plate respectively. The upper portion of the upper base plate is fixedly connected with a gear motor, the lower end of the gear motor penetrates through the upper base plate and is rotationally connected with a plum coupling, the other end of the plum coupling is connected with a T-shaped square key in an engaged mode, and the bottom end of the T-shaped square key is fixedly connected with a driving shaft. The scraper is driven by the chain wheel to rotate, and the scraper is driven by the cam mechanism to move up and down, so that manual operation is replaced, and the functions of stirring a sodiu
