The soil remediation agent filling device comprises a floating seat 10, a silo 20 and a feeding mechanism 30. The floating seat 10 comprises a support frame 11 and a floating cylinder 12 fixedly installed at the bottom of the support frame 11. The floating cylinder 12 is used to provide buoyancy for the feeding device so that the feeding device floats on the water surface. At least one feeding mechanism 30 is installed on the peripheral side of the support frame 11. The silo 20 is installed in the middle of the support frame 11. The silo 20 is connected to the feeding mechanism 30 to provide soil remediation agents for the feeding mechanism 30. In this embodiment, the soil remediation agent is a liquid remediation agent.

[0028] See also Figure 4 and Figure 5 The feeding mechanism 30 includes a feeding outer cylinder 31 and an inner cylinder 32 slidably mounted inside the feeding outer cylinder 31. Both ends of the feeding outer cylinder 31 are open, and one end of the feeding outer cylinder 31 is connected to the silo 20. A soil remediation agent inlet is provided on one side of the inner cylinder 32, and a soil remediation agent delivery port is provided on the other side of the inner cylinder 32.
