A certain space is required between the liquid surface and the top surface of the shell 2 to prevent the third sealing plate 48 above from being immersed in the soil restoration agent. After the filling work is completed, the staff can use the base 1 to drive the device to move to the mine waste land;

[0100] Before the soil remediation work is carried out, the staff needs to develop a reasonable plan according to the topography and the ecological damage of the abandoned land, and move the device to the corresponding point according to the plan. After reaching the designated point, the staff needs to first stabilize the base 1, and then step on the pedal 45 from the rear. With the descent of the pedal 45, the connecting rod 44 on it will also drive the piston plate 42 to descend, and the space between the bottom surface of the piston plate 42 and the inside bottom surface of the shell 41 will be reduced. Since the inlet pipe 46 and the outlet pipe 47 are both elastically connected to the third sealing plate 48 by the third reset member 49, air in the shell 41 can only follow the path of entering from the inlet pipe 46 and exiting from the outlet pipe 47, and cannot flow freely. Therefore, the gas in the shell 41 will be squeezed into the inside of the casing 2. Similarly, during the subsequent process of the piston plate spring 43 pushing the piston plate 42 back to its original position, the gas in the casing 2 cannot return to the inside of the shell 41, and the expanded space in the shell 41 will be filled with external air flowing in from the inlet pipe 46.

[0101] The air pressure inside the casing 2 will increase after the air enters, but the pipe cover 4 is fixed to the upper end of the inlet pipe 3 by multiple screws and two flanges with threaded holes, and a sealing ring is provided on the bottom surface of the pipe cover 4, which can effectively prevent air from overflowing or seeping in. Therefore, the increase in air pressure causes the soil remediation agent in the casing 2 to be squeezed into the injection barrel 6 through multiple connecting pipes 12. The end of the connecting pipe 12 near the injection barrel 6 is also provided with a structure similar to a one-way valve, and the elastic member second reset member 38 in this structure is protected by the sleeve 37, so there is no problem of soil remediation agent eroding the elastic member. After the soil remediation agent enters the injection barrel 6, it will exert a downward squeezing force on the piston part 8. Although the piston part 8 is provided with holes for liquid to pass through, the soil remediation agent cannot enter the liquid chamber 10 through the adapter pipe 15 because the adapter pipe 15 is blocked by the first sealing plate 30 at this moment.

[0102] With the increase of soil remediation agent in the injection cartridge 6, the piston part 8 will continue to drop, and then it will make the drill rod part 9 also continue to drop through the adapter pipe 15, and the guide groove 16 on the drill rod part 9 will be extruded by the guide piece 17 during the dropping process. The guide piece 17 is arranged in a hemispherical structure to greatly reduce the friction between it and the guide groove 16. Under the interaction between the two, the drill rod part 9 will rotate during the dropping process. In addition, the drill bit part 18 is arranged, so the drill rod part 9 can easily break through the soil surface and drill into the soil layer under the guidance of the drill bit part 18. When the drill bit part 18 drops, the larger diameter part at its upper part will come into contact with the rotating plate 27. Because the rotating plate 27 is connected to the fixed plate 25 at the bottom, it can be deflected downward. In this way, it can prevent the drill bit part 18 from being extruded and causing damage to the rotating rod 21 when it drops. After the drill bit part 18 moves to the position below the rotating plate 27, it can return to its original state under the rotation force of the torsion spring 28;

[0103] After the drill bit part 18 drills into the soil layer, a hole will be left on the soil surface, and the drill rod part 9 will also fall into the hole. When the piston part 8 moves to the lowest point, the position of the first sealing plate 30 will correspond to the position of the unlocking piece 36. At this moment, the unlocking piece 36 will generate an attractive force to the magnetic metal-made locking reset piece 34 and the locking piece 35. Then the locking piece 35 will move outward and shrink into the plate groove 33. At this time, the first sealing plate 30, which has lost the fixation of the locking piece 35, can be flipped along the position connected to the rotating shaft 29. The position of the locking piece 35 is at the same height as the rotating shaft 29 but is staggered. The first sealing plate 30 will flip in the first time due to the loss of the fixation of the locking piece 35 and the pressure of the water pressure above the injection cartridge 6. Then the soil remediation agent in the injection cartridge 6 will continuously flow through the two sides of the first sealing plate 30 and flow into the liquid chamber 10. Then the soil remediation agent will flow through the liquid chamber 10 and the medicine outlet 11 in turn and flow out of the device into the hole drilled by the drill bit part 18. The multiple flow guide grooves 19 on the drill bit part 18 are provided for the soil remediation agent to flow through. The diameter of the upper part of the drill bit part 18 is set to be larger. Firstly, it is used to cooperate with the rotating plate 27. Secondly, it is used to prevent the soil on the inner wall of the hole from contacting the medicine outlet 11 and causing the medicine outlet 11 to be blocked. At the same time, it also provides a temporary storage space for the soil remediation agent to avoid the soil remediation agent being taken out of the hole by the drill bit part 18 or being blocked by the inner wall of the hole, which will cause a large amount of soil remediation agent to flow out after the drill bit part rises. This will cause the soil remediation agent to not stay in the hole to repair the deep soil layer. The soil absorption capacity of some abandoned mine land is not fast enough to absorb the soil remediation agent at the same time as the soil remediation agent is applied.

[0104] During the process of injecting the soil remediation agent into the hole, the water pressure inside the injection cartridge 6 is suddenly reduced, and the piston part 8 is also reset under the resilience of the tightened drill rod reset part 14. During the resetting process, the first sealing plate 30 is also reset, but the first sealing plate 30 cannot be reset during the rising process because the space above the piston part 8 is shrinking and the air in the space can only overflow the injection cartridge 6 from both sides of the first sealing plate 30. However, the locking parts 35 on both sides have been pushed out of the plate slot 33 by the locking reset part 4 because the suction force is lost. Only when the piston part 8 returns to its original position and the air pressure inside the injection cartridge 6 returns to its original state, the first sealing plate 30 can be rotated under the action of the first reset part 32. The two locking parts 35 are both provided with inclined surfaces and are centrally symmetrically arranged. Therefore, the positions of the inclined surfaces of the two locking parts 35 correspond to the positions where the first sealing plate 30 is pressed during the rotation process. Then, the two locking parts 35 are pressed into the plate slot 33, and then are popped out and clamped to the first sealing plate 30 to block the adapter pipe 15 under the action of the locking reset part 34.

[0105] On the other hand, the rising of the drill bit part 18 will again press the bottom surface of the rotating plate 27 through the top surface of the drill bit part 18. However, the hinged position of the rotating plate 27 and the fixed plate 25 on the bottom surface cannot be upwardly turned, so the rotating plate 27 can only rotate the fixed plate 25 and the rotating rod 21 together. The rotation of the rotating rod 21 will make the spring rod 24 between the rotating rod 21 and the bottom surface of the base 1 be stretched (the spring rod is a common telescopic rod with a spring added, which can be stretched by the outside end of the rotating rod 21 being pulled down and can return to its original state after the external force disappears). During the upward turning process of the rotating plate 27, the vertical plate 22 at the other end of the rotating rod 21 and the plurality of soil covering rakes 23 will be gathered to the middle. The plurality of soil covering rakes 23 are arranged in a four-pyramid structure, so that the soil can be more easily broken and gathered to the opening end of the hole through the soil covering rakes 23 on the plurality of vertical plates 22. In this way, the opening end of the hole can be blocked, and the soil layer around the hole can be loosened by this pressing method, so as to avoid the soil in the hole wall being too compact due to the pressing of the drill bit part 18, which causes slow water absorption. This method not only improves the absorption speed of the soil layer to the soil remediation agent, but also avoids the evaporation loss of the soil remediation agent in hot weather, and also flattens the soil surface and loosens the soil to make the hole collapse.
