Concrete raw material proportioning device

The utility model belongs to the technical field of concrete proportioning, and particularly relates to a concrete raw material proportioning device which comprises a mixing cylinder, the top end of the mixing cylinder is fixedly connected with a proportioning frame, the top end of the proportioning frame is fixedly connected with a material cylinder, and the inner wall of the proportioning frame is fixedly connected with a fixed baffle. By arranging the fixed baffle and the proportioning baffle, the handle drives the proportioning baffle and the fixed baffle to rotate relatively through the positioning frame, meanwhile, the positioning frame rotates to drive the pointer to slide along the outer wall of the graduated scale, and when the proportioning baffle rotates to a proportioning angle, the pressing rod is loosened, so that the graduated scale is positioned. According to the concrete proportioning device, a positioning spring is arranged on the outer wall of a telescopic block, so that the positioning spr
