Technical Field

[0001] The utility model belongs to the technical field of soil remediation, and in particular relates to a nutrient solution injection device for soil remediation. Background Art

[0002] The nutrient solution injection device for soil remediation is a device specifically used to inject nutrient solution into the soil.

The design principle, structural characteristics, functional description, and application scenarios of the device all reflect its professionalism and practicality.

[0003] Most nutrient solution injection devices for soil remediation have some shortcomings when in use, such as: when in use, the nutrient solution injection device for soil remediation adopts the method of spraying the repair liquid on the soil surface, but this method can only repair the surface and cannot effectively repair the deeper layers of the soil. At the same time, since the nutrient solution is usually mixed with multiple liquids, this method of directly pouring them into the liquid storage tank for mixing often makes the nutrient solution sprayed from the injection device uneven, which may affect the soil absorption effect. In view of this, we propose a nutrient solution injection device for soil remediation. Utility Model Content
