The invention discloses a dicing machine and relates to the field of fruit dicing technological equipment. The dicing machine comprises two stand columns and a fixing frame mounted on the stand columns. A hopper is fixedly mounted on the fixing frame. A latticed dicing cutter is mounted in the hopper. A slidable transverse cutter is arranged below the dicing cutter. The tail of the transverse cutter penetrates out of the hopper. A mounting rack is mounted on the stand columns. A driving motor is mounted on the mounting rack. A screw rod is fixedly connected to an output shaft of the driving motor through a coupler. A nut matched with the screw rod is arranged on the screw rod. A connecting rod is hinged to the nut. The other end of the connecting rod is hinged to the tail of the transverse cutter. A mounting plate is also fixedly mounted at the upper ends of the two stand columns. A push cylinder is mounted on the mounting plate. A piston rod of the push cylinder penetrates through the mounting plate downwards. A fixed plate is mounted on the piston rod of the push cylinder. A plurality of push rods which are disconnected are arranged on the fixed plate. The dicing machine is uniform in dicing and convenient to use, manual operation is not needed, and the labor force so reduced.
