Problems solved by technology
[0003] The existing raw material mixing device for civil engineering concrete preparation includes a mixing tank and a mixing motor. The inside of the mixing tank is fixedly connected with a helical blade. The motor drives the mixing tank to rotate, and the helical blade drives the internal mixture to roll and stir. The rotation speed of the bucket is slow, and it takes a long time to stir to complete the mixing. At the same time, because the weight of the stone aggregate is relatively heavy, during the rotation of the mixing bucket, most of the stone aggregate rolls at the bottom of the mixing bucket, which is inconvenient. Mixing the stone aggregate at the bottom with other mixtures in the upper part reduces the uniformity of mixing and reduces the quality of concrete

Description
technical field [0001] The invention relates to the technical field of concrete preparation equipment, in particular to a raw material mixing device for concrete preparation in civil engineering. Background technique [0002] As we all know, the raw material mixing device for concrete preparation is to mix the mixture of cement, sand and stone as aggregate and water in a certain proportion to form concrete required for civil engineering, which is widely used in the technical field of concrete preparation equipment. [0003] The existing raw material mixing device for civil engineering concrete preparation comprises a mixing barrel and a stirring motor. The inside of the mixing barrel is fixedly connected with a spiral blade, the motor drives the mixing barrel to rotate, the spiral blade drives the internal mixture to tumble and stir, and the stirring motor drives the stirring The rotation speed of the barrel is slow, and it takes a long time to stir to complete the stirring....
