Conveying structure for concrete mixer

The utility model discloses a conveying structure for a concrete mixer. The conveying structure comprises a mixer body and a protective cover, the limiting device, the limiting block, the stabilizing hole, the spring and the limiting groove are matched for use, so that the problem that concrete is an indispensable important material during existing road and bridge construction is solved, and the concrete mixer is a machine for mixing cement, gravel aggregate and water and mixing the mixture into a concrete mixture; when the concrete mixer is used, mixing materials are poured into the mixer body, then the mixer body is started, the proportion of the concrete mixing materials is required, the mixing materials poured into an inner cavity of the mixer body also need to be quantified, and generally, the mixing materials are directly poured into the inner cavity of the mixer body by people. The concrete mixer solves the problem that the existing concrete mixer is not provided with a component for quantitatively con
