The invention provides an autoclaved lime-sand brick conveying device. The autoclaved lime-sand brick conveying device comprises a mounting seat, a conveying box is fixedly connected to the upper surface of the mounting seat, the lower surface of the mounting seat is fixedly connected with a driving motor, the output end of the driving motor is rotatably connected with a driving gear through a coupler, a conveying barrel is arranged in the conveying box, and one end of the conveying barrel is rotatably connected to the corresponding inner side wall of the conveying box through a rotating device. The autoclaved lime-sand brick conveying device has the beneficial effects that in the material conveying process, different materials slide into feeding pipes from two feeding tunnels and are conveyed into the conveying barrel from the feeding pipes, the different raw materials entering the conveying barrel ceaselessly rotate in the conveying barrel and are pushed towards an outlet due to ceaseless stirring of helical blades in the conveying barrel, after the raw materials are poured out, raw material stirring is completed, the raw materials are stirred in the raw material conveying process, and the production efficiency of autoclaved lime-sand bricks is improved simply and conveniently.
