Dry material mixing device for quartz stone plate production

The utility model discloses a dry material mixing device for quartz stone plate production, and relates to the field of quartz stone plate production. Comprising a stirring barrel, a discharging opening is fixedly formed in the side wall of the stirring barrel, a sealing plate is fixedly installed on the side wall of an inner cavity of the stirring barrel, an output motor is fixedly installed on the side wall, away from the opening end, of the inner cavity of the stirring barrel, and the output end of the output motor is inserted into the upper end face of the sealing plate and provided with a limiting mechanism used for limiting a stirring shaft. The axial end of the mounting disc is attached to the axial end of the limiting disc, at the moment, the axial end of the inserting rod is inserted into the inner cavity of the inserting groove, clamping teeth and limiting teeth are clamped, and therefore the mounting disc can be prevented from sliding in the axis direction while being limited to rotate in the axis
