Description

Technical Field

[0001] The present application relates to the field of soil remediation, and more specifically, to a stirring device for soil remediation. Background Art

[0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to transform toxic and harmful pollutants into harmless substances. Crushing the soil to mix it with the repair agent is a means of soil remediation. The patent document with the prior art publication number CN216125521U provides a stirring device for soil remediation. The device cooperates with the stirring mechanism, the power mechanism, the dosing mechanism and the reflux mechanism. The power mechanism can make the stirring mechanism and the reflux mechanism work. At the same time, when the stirring mechanism rotates, the soil inside the vertical cylinder can be stirred more evenly. At the same time, the reflux mechanism can stir the soil more evenly, and the dosing mechanism can evenly add the mixture to the soil. Then, after stirring by the stirring mechanism and the reflux mechanism, the mixture and the soil can be stirred more evenly.

[0003] In view of the above-mentioned related technologies, the inventor believes that although the device can evenly mix the soil and the agent, the soil needs to be crushed in advance, otherwise the agent will not be able to effectively penetrate into the soil, which will increase the complexity of soil remediation work. Therefore, we propose a stirring device for soil remediation. Utility Model Content

[0016] Optionally, a partition is provided in the mixing drum, the partition is fixedly connected to the connecting rod, and the gear B is rotatably connected to the partition.

[0017] By adopting the above technical solution, the bottom of the partition can facilitate the movement of soil to one side of the mixing drum, and the partition is arranged on one side of the gear ring to prevent the soil from falling onto the gear ring when the mixing drum drives the soil to roll.
