Microorganism adding device for soil remediation

The utility model discloses a microorganism adding device for soil remediation, relates to the technical field of soil remediation, and solves the technical problems that the microorganism adding device in the prior art can only prepare a microorganism solution with a single concentration every time and cannot be continuously operated and used, so that the adding efficiency of the microorganism solution is relatively low. Comprising a mounting frame, a material adding box and a liquid spraying structure, the mixing bins and the liquid storage bins are arranged in the feeding box, the bases are arranged on the feeding box, the linkage gears are rotationally arranged on the bases, the stirring rods are arranged in the liquid storage bins and connected with the linkage gears respectively, and the electric valves are arranged on liquid outlets of the mixing bins. By adopting the design of a plurality of mixing bins and one liquid storage bin, a plurality of microbial preparation solutions with the same concentrat
