Production line of solid soil improving/repairing agent

The utility model discloses a production line of a solid soil improving/repairing agent. The production line comprises a mixing barrel, a first mixing shaft, a second mixing shaft, a driving mechanism, a solid material conveying mechanism, a buffer hopper and a weighing and packaging machine, one end of the solid material conveying mechanism is located at a discharging opening of the mixing hopper, the other end of the solid material conveying mechanism extends into the buffer hopper, the solid material conveying mechanism is used for conveying solid materials in the mixing barrel into the buffer hopper, and the buffer hopper is located above the weighing and packaging machine. According to the utility model, the two mixing shafts which rotate relatively are adopted to fully scatter all raw materials to realize uniform mixing, and meanwhile, the bottom wall and the two side walls of the horizontally arranged mixing barrel are parallel to the mixing shafts, so that the raw materials move in the mixing barrel w
