[0002] The soil remediation agent delivery device is a device specifically designed to evenly deliver soil remediation agents to the soil. This device is designed to address the problem of localized over- or under-delivery that can occur with traditional delivery methods, ensuring that the remediation agent and soil are fully and evenly mixed, improving soil remediation effectiveness.

[0003] For example, the Chinese patent with the announcement number CN220942534U discloses a device for dispensing soil remediation agents, including a box body, a control panel provided at the center of one side wall of the box body, a handle provided at the center of one side wall of the box body, a hopper provided at the center of the upper end face of the box body, a soil breaking device provided at the center of the lower end face of the box body, a spraying device provided at the lower end face of the box body on one side of the soil breaking device, a processing device provided at the lower end face of the box body on one side of the spraying device, a moving device provided at the lower end face of the box body, and three storage boxes arranged front and back at one side of the center of the box body. In the present utility model, the soil breaker is driven to rotate by the rotation of the roller. Under the action of the roller, the soil breaker contacts the soil and applies force, breaking the soil, improving the soil structure, and increasing the soil aeration and permeability, thereby creating a good foundation for the dispensing of soil remediation agents and soil restoration.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used. For example, while the soil remediation agent delivery device can break up the soil to be remediated, the length of the blades in the soil breaker cannot be adjusted according to usage requirements. This can result in less than ideal soil remediation results when the contaminated soil is deep. In light of this, we propose a soil remediation agent delivery device. Utility Model Content
