[0027] In actual use, the material enters the interior of the mixing shell 1 through the first feed hopper 2 and the first motor 12, and the first baffle 22 and the second baffle 23 are provided, and the first baffle 22 and the second baffle 23 are in a Z shape, so that the material will be blocked by the first baffle 22 and the second baffle 23 to prevent the aggregate in the material from hitting the components inside the mixing shell 1 and causing damage, and the Z shape can also effectively block the flow of air inside and outside, and prevent the internal rotating machinery from causing cement and other powders to fly and cause workers' pneumoconiosis, and can also block the external humid air to prevent the concrete from being too thin due to excessive moisture.
[0028] A water inlet 13 is fixedly mounted on the upper end of one side of the mixing shell 1 . The water inlet 13 is communicated with the interior of the mixing shell 1 . The water inlet 13 is used to provide water required for concrete mixing.
[0029] A central column 3 is provided in the middle position inside the stirring shell 1, and a plurality of stirring blades 31 are fixedly installed on the side surface of the central column 3. The two ends of the central column 3 are rotatably installed inside the stirring shell 1 and in the middle of the stirring top plate 11 respectively. Scraper assemblies 4 are detachably installed on both sides of the central column 3. A first motor 12 is fixedly installed in the middle of the upper surface of the stirring top plate 11, and the driving end of the first motor 12 passes through the stirring top plate 11 and is fixedly installed on the end of the central column 3.
[0030] During use, when the material enters the mixing shell 1 through the proportioning, a proper amount of water is added into the inside thereof through the water inlet 13, and then the first motor 12 works to drive the central column 3 and the stirring blades 31 to work. The stirring blades 31 are discontinuous inclined blades, so that the device can achieve horizontal stirring and vertical stirring in a certain direction, driving the raw materials to tumble inside the mixing shell 1, thereby making the stirring more sufficient without causing excessive powder to fly.
