[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. In the soil remediation industry, there are more than 100 existing soil remediation technologies and more than 10 commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and implemented contaminated soil treatment and remediation plans, thus forming an emerging soil remediation industry.

[0039] A method for ecological restoration of multi-type land soil, comprising the following steps:

[0040] S1: Collect the soil that needs to be repaired and then dry the collected soil;

[0041] S2: crushing the dried soil;

[0042] S3: Filter the crushed soil to remove impurities such as roots of trees, flowers and plants in the soil, and wait for the soil to be repaired;

[0043] S4: transporting the soil to be repaired to the soil repair equipment, and transporting the repair liquid into the soil;

[0044] S5: The repaired soil is then subjected to solution extraction, drying, grinding, and pollutant detection to obtain the repaired soil.

[0045] In this embodiment, the soil to be repaired obtained after filtration is transported to the repair tank 1 through the feed hopper 4. At this time, the medicine feed pipe 13 is connected to the pipeline for transporting the repair liquid. At this time, the repair liquid is transported into the pipe 12 and the rotating tube 9 through the medicine feed pipe 13. At this time, the driving member 20 is started, and then the driving member 20 will drive the rotating shaft 19 to rotate, and then drive the rotating shaft 19 to rotate, and then drive the first flat gear 18 to rotate, and then drive the half-speed gear 15 to rotate, and then drive the rotating tube 9 to rotate, so that the rotating tube 9 corresponds to the through hole 10 on the outer sleeve 8. At this time, the half-speed gear 15 is out of mesh with the first flat gear 18, and will not drive The half-distance gear 15 continues to move, so in the process of conveying the repair liquid, the rotating tube 9 and the through hole 10 on the outer sleeve 8 are always connected, and the repair liquid is transported into the repair tank 1 and directly transported to the deep soil, which is convenient for the rapid mixing of the repair liquid and the soil. In the process of rotation of the rotating shaft 19, the third flat gear 25 will be driven to rotate, and then the second flat gear 24 will be driven to rotate, and then the connecting sleeve 23 will be driven to rotate, and then the connecting frame 21 will be driven to rotate, and then the stirring rod 22 will be driven to rotate, and then the soil in the repair tank 1 is stirred by the rotating stirring rod 22, thereby accelerating the mixing efficiency of the repair liquid and the soil, and thus improving the repair efficiency.

[0046] In the present embodiment, during the soil remediation process, the driving member 20 runs forward, and thus will not drive the cleaning assembly 7 to run. When the repair liquid is repaired, the driving member 20 is reversed, and thus the cleaning assembly 7 is run, thereby cleaning the outer surface of the stirring rod 22 and the inner wall of the repair tank 1, and the first spur gear 18 will be driven to reverse during the reverse operation. At this time, due to the action of the torsion spring 16, the half-distance gear 15 is meshed with the first spur gear 18, thereby driving the half-distance gear 15 and the rotating tube 9 to rotate in the opposite direction and reset. During the continuous reversal of the driving member 20, the half-distance gear 15 will be disengaged from the first spur gear 18 again, and thus will not drive the rotating tube 9 to rotate continuously. Therefore, the positions of the two groups of through holes 10 are staggered, and thus the repair liquid will not continue to be transported. The two groups of through holes 10 are staggered to prevent soil from entering, and to prevent the rotating tube 9 from being blocked. Moreover, due to the setting of the filter cloth 11, soil is further prevented from entering the rotating tube 9 and causing the rotating tube 9 to be blocked.

[0047] Example 2

[0048] See also Figure 7-Figure 9 Example 2 is described. This embodiment further describes Example 1. The cleaning assembly 7 in the figure includes a cleaning plate 26 installed at the bottom end of the connecting frame and sleeved on the outer surface of the multiple groups of stirring rods 22. The cleaning plate 26 is rotatably connected to a rotating ring 27. The rotating ring 27 is threadedly connected to a threaded rod 28 rotatably connected to the repair tank 1. The top of the threaded rod 28 is fixedly connected to a connecting shaft 29 extending to the top of the repair tank 1 and rotatably connected to the repair tank 1. The connecting shaft 29 is connected to the driving member 20, and an elastic member 34 is connected to the outer surface. A cleaning ring 31 is fixedly connected to the rotating ring 27 and is arranged to contact the inner wall of the repair tank 1. The cleaning ring 31 is connected to a rotating member 30 connected to the connecting shaft 29.

[0049] See also Figure 7-Figure 9 The rotating member 30 shown in the figure includes a gear ring 32 fixedly connected to the cleaning ring 31, and the inner side of the gear ring 32 is meshed with a fourth flat gear 33 sleeved on the outer surface of the connecting shaft 29. The fourth flat gear 33 is movably connected to the threaded rod 28 and is rotatably connected to the rotating ring 27. A limit block 35 is fixedly connected to the connecting shaft 29 and the threaded rod 28 for sliding connection, and a limit groove 36 adapted to the limit block 35 is provided on the connecting shaft 29 and the threaded rod 28.

[0050] See also Figure 7 and Figure 8 The elastic member 34 shown in the figure includes a movable sheet 37 sleeved on the outer surface of the connecting shaft 29, one end of the movable sheet 37 is fixedly connected to a spring 38 sleeved on the outer surface of the connecting shaft 29, one end of the spring 38 is fixedly connected to a fixed sheet 39 fixedly connected to the connecting shaft 29, and the movable sheet 37 is located at the connection position of the connecting shaft 29 and the threaded rod 28.

[0051] In this embodiment, when the driving member 20 is running, the connecting shaft 29 will rotate, thereby driving the threaded rod 28 to rotate. When the driving member 20 is running in the forward direction, the threaded rod 28 rotates forward at this time, and the rotating ring 27 is located on the connecting shaft 29 to squeeze the spring 38, so that the rotating ring 27 will not be driven to move when the threaded rod 28 rotates forward. When the soil remediation is completed, the driving member 20 runs in the reverse direction, thereby driving the connecting shaft 29 and the threaded rod 28 to rotate in the reverse direction, and then the spring 38 releases the elastic force at this time so that the rotating ring 27 and the threaded rod 28 fit closely, thereby driving the rotating ring 27 to move, and then driving the cleaning plate 26 to move, and then driving the cleaning ring 31 to move, thereby cleaning the outer surface of the stirring rod 22 and the inner wall of the repair tank 1, and during the rotation of the stirring rod 22, since the cleaning plate 26 is rotatably connected to the rotating ring 27, the cleaning plate 26 and the rotating ring 27 keep rotating during the repair and cleaning process.

[0052] In the present embodiment, when the connecting shaft 29 and the threaded rod 28 rotate, due to the action of the limit block 35 and the limit groove 36, the fourth flat gear 33 is driven to rotate, which in turn drives the gear ring 32 to rotate, and then drives the cleaning ring 31 to rotate, thereby improving the cleaning efficiency of the inner wall of the repair tank 1 through the rotating cleaning ring 31, and because the fourth flat gear 33 is rotatably connected to the rotating ring 27, the fourth flat gear 33 always follows the movement of the rotating ring 27 and will not disengage from the gear ring 32.

[0053] Example 3

[0054] See also Figure 2 and Fig.10 Example 3 is described. This embodiment further illustrates Example 1.

The outer surface of the driving shaft 43 is connected to a transmission member 44 connected to the rotating shaft 19.

[0055] See also Figure 2 and Fig.10 The transmission member 44 shown in the figure includes a driving wheel 45 fixed to the outer surface of the driving shaft 43, the outer surface of the driving wheel 45 is transmission-connected with a belt 46, and one end of the belt 46 is transmission-connected with a driven wheel 47 fixedly connected to the rotating shaft 19.

[0056] In this embodiment, by starting the drive motor 41, the coupling 42 will be driven to rotate, which will drive the drive shaft 43 to rotate, and then drive the connecting shaft 29 fixedly connected thereto to rotate. When the drive shaft 43 rotates, the driving wheel 45 will also be driven to rotate, which will drive the belt 46 to rotate, and then drive the driven wheel 47 to rotate, and then drive the rotating shaft 19 fixedly connected thereto to rotate.
