[0025] The installation component includes an installation part 5 and a driving mechanism and a connecting mechanism arranged on the installation part 5; the drilling part 2 is used for drilling when the medicine injection part 1 injects medicine, reducing the resistance when the medicine injection part 1 is inserted into the soil. The function of drilling is to inject medicine into different formation depths. The limiting part 3 is used for multiple groups of limiting parts 3 to be installed equidistantly inside the medicine injection part 1 and block and divert the medicine liquid to prevent the medicine liquid from remaining inside the medicine injection part 1. The water dispersing pipes 4 are used for the medicine liquid to be further divided and spread into the soil through the medicine injection holes of the medicine injection part 1. By setting the medicine injection holes at multiple angles and positions, the spreading area and scope of the medicine liquid in the soil are increased. The installation component is used for installing the medicine injection part 1 and providing power.

[0026] A novel soil in-situ remediation drug injection device of the present utility model, the driving mechanism includes a driving member 6 rotatably arranged inside the mounting member 5 and a connecting member 8 arranged on the drug injection member 1. One end of the connecting member 8 is provided with a first gear 7, the drug injection member 1 is provided with a second gear 9, the first gear 7 is meshed and connected with the second gear 9. The first gear 7 is provided with a multi-sided shaft cavity, and the driving member 6 is in fit connection with the shaft cavity of the first gear 7; the connecting member 8 is used for rotatably supporting the first gear 7 on the drug injection member 1. The first gear 7 is provided with a multi-sided shaft cavity so that the driving member 6 can drive the first gear 7 to rotate. At the same time, after the connection position of the first gear 7 and the driving member 6 is adjusted, their transmission relationship remains unchanged. The meshed connection between the first gear 7 and the connecting member 8 enables the driving member 6 to drive the drilling member 2 on the drug injection member 1 to rotate, facilitating the injection hole to drill into the ground.

[0027] A novel soil in-situ remediation drug injection device of the present utility model, the driving mechanism further includes a threaded rod 10 arranged inside the mounting member 5. The other end of the connecting member 8 is provided with a screw sleeve 11, and the screw sleeve 11 is in fit threaded connection with the threaded rod 10; the rotation of the threaded rod 10 and the threaded connection with the screw sleeve 11 are used for the connecting member 8 to drive the drug injection member 1 to perform position lifting adjustment. Through the arrangement of the threaded rod 10 and the driving member 6, the movement track of the connecting member 8 is limited to prevent rotation. Here, it should be noted that the threaded connection combination of the threaded rod 10 and the screw sleeve 11 can save more space for the position lifting of the drug injection member 1 compared with mechanisms such as cylinders.

[0028] A novel soil in-situ remediation drug injection device of the present utility model, the connecting mechanism includes at least two groups of positioning members 12 arranged inside the mounting member 5. A moving member 13 is arranged on the multiple groups of positioning members 12. A rotating connecting pipe 14 is arranged on the moving member 13. The rotating connecting pipe 14 is arranged in an L-shaped structure. The rotating connecting pipe 14 is in fit and rotatable connection with the drug injection member 1.

One end of the rotating connecting pipe 14 is located outside the mounting member 5 and is connected with the drug supply pipe; the multiple groups of positioning members 12 limit the movement track of the moving member 13. The moving member 13 is used for supporting the rotating connecting pipe 14 to ensure the connection angle between the rotating connecting pipe 14 and the drug injection member 1. The rotating connection between the rotating connecting pipe 14 and the drug injection member 1 enables the drug injection member 1 to drive the rotation without being affected and can maintain the communication state. The connection between the moving member 13 and the connecting member 8 ensures the connection strength and stability between the rotating connecting pipe 14 and the drug injection member 1 when the position of the drug injection member 1 is adjusted.

[0029] A novel soil in-situ remediation drug injection device of the present utility model, the rotation direction of the drilling member 2 is correspondingly set with the rotation direction of the threaded rod 10; the corresponding setting of the rotation direction of the drilling member 2 and the rotation direction of the threaded rod 10 enables the drilling member 2 on the drug injection member 1 to be in a downward spiral drilling angle when the drug injection member 1 is driven downward, improving the cooperation stability of the device.

[0032] When the novel soil in-situ remediation drug injection device of the present utility model is working, first, the mounting member 5 is fixed on a mobile machine, then the drug supply pipe is communicated with the limiting member 3, and then the mobile machine moves the mounting member 5 to a set position. After that, the servo motor 15 is started, and then the third gear 16 meshes with the fourth gear 17 and the fifth gear 18 to synchronously drive the threaded rod 10 and the driving member 6 to rotate. The threaded rod 10 is in threaded cooperation with the screw sleeve 11, so that the connecting member 8 drives the drug injection member 1 to descend. At the same time, the driving member 6 drives the first gear 7 to rotate and mesh with the second gear 9 to provide rotational power to the drug injection member 1. When the drilling member 2 contacts the soil, synchronous drilling is carried out. After the drug injection member 1 is inserted to a set depth, the rotation of the servo motor 15 stops. At this time, the drug supply pipe injects drugs into a plurality of water dispersing pipes 4 through the adapter pipe 14. After the drug injection is completed, the servo motor 15 rotates reversely, and the threaded rod 10 and the screw sleeve 11 cooperate to drive the drug injection member 1 to move upward and reset by the first gear 7. At the same time, the drug injection member 1 drives the drug injection member 1 to rotate reversely.
