[0002] The soil remediation mixing device is a key equipment specially used in the soil remediation process. It is mainly used to fully mix contaminated soil with remediation liquid or other additives to promote chemical reactions between pollutants in the soil and remediation agents, thereby reducing the concentration of pollutants in the soil and achieving the purpose of soil remediation.

[0003] For example, the Chinese patent with the announcement number CN217646309U8 discloses a soil remediation stirring device, including an outer shell and a top cover, which is characterized in that the upper side of the outer shell is fixedly connected to the top cover, a connecting platform is fixed on the upper side of the top cover, a number of support seats are fixed on the lower side of the connecting platform, the support seats are fixedly connected to the upper side of the top cover, a stirring device is provided on one side of the connecting platform, a feeding device is provided on the upper side of the top cover, a screening plate is provided on the inner side of the outer shell, a crushing device is provided on the inner side of the outer shell, a feeding device is provided on the outer side of the outer shell, a discharging device is provided on the outer side of the outer shell, and a number of circular support seats are fixed on the lower side of the outer shell. By arranging a small gear, a large gear, a rotating shaft, a motor, a driven shaft, a stirring rod, a feeding box, a water pipe A, a waterproof pad A, a shock-absorbing plate, a water flow box, a waterproof pad B, a material adjustment plate, a water flow trough, a waterproof pad C, a pad, a water flow pipe, and a cylinder, the device has the function of convenient stirring and automatic addition of remediation liquid.

[0004] The above patent has the following problems:

[0005] This patent has some drawbacks during use. For example, when the device is used, all the required remediation fluid is added to the mixing barrel at once. This may result in some areas having too high a concentration of remediation fluid while others have too low a concentration, leading to uneven mixing. Furthermore, when the device is used, the soil may contain large stones, which may come into contact with the stirring blades, potentially damaging them and causing economic losses. In light of these shortcomings, we propose a stirring device for soil remediation. Utility Model Content
