This utility model provides a
refractory brick cutting device, including a support frame, a
processing table on the upper surface of the support frame, a slide table slidably disposed within a guide groove on the upper surface of the
processing table, a rotating plate rotatably disposed on the upper surface of the slide table, a bracket in the middle of the
processing table, a drive box on the upper surface of the support frame, a sliding groove on the lower surface of the drive box, evenly distributed sliding plates slidably disposed inside the sliding groove, a support rod on the lower surface of each sliding plate, a
cutting blade rotatably disposed at the bottom end of each support rod via a rotating shaft, and a second motor at the bottom end of each support rod, the output shaft of the second motor being fixed to the rotating shaft by a
coupling. With the
refractory brick cutting device described in this utility model, the position of the cutting blade and the arrangement of the
refractory bricks can be quickly and stably adjusted, so as to better
cut refractory bricks of different specifications, reduce personnel intervention, and facilitate use.
