[0002] Due to excessive use of soil and the large-scale spraying of chemical products such as pesticides, fertilizers, and heavy metals, the degree of soil pollution is extremely serious. Among the many soil treatment methods, soil microbial remediation is a relatively effective treatment method. It disperses specific microorganisms into the soil. Under suitable environmental conditions, microorganisms reduce the activity of harmful pollutants in the soil or degrade them into harmless substances through their own metabolism. This remediation technology has a low application cost and little negative impact on soil fertility and metabolic activity. Therefore, it is widely used in the field of soil treatment.

[0003] Since pollutants mainly exist inside the soil, and the content is the highest within a certain depth of the soil, it is necessary to inject microbial remediation liquid into the soil to effectively achieve the full decomposition of pollutants in the soil.

A piston liquid pressing part that can reciprocate up and down is arranged inside the hollow soil-breaking rod 601 (a plurality of discharge ports are opened on the side of the hollow soil-breaking rod 601 near the bottom, and each discharge port in the initial state is connected to the soil-breaking rod 601. The hollow soil-breaking rod 601 is sealed by the piston pressure liquid part), and a hollow guide plate 603 connected to it is fixedly installed on the side surface thereof; the bacteria liquid diversion assembly 7 includes a hollow guide cover 701 which can reciprocate up and down, the hollow guide plate 603 is rotatably arranged inside the hollow guide cover 701 and the two are connected, and a bacteria liquid transfer part which moves synchronously with it is installed on one side of the hollow guide cover 701, and the bacteria liquid transfer part is connected to the hollow guide cover 701, and the bacteria liquid storage box 401 and the bacteria liquid transfer parts on both sides thereof are connected through gravity hoses.

[0037] In this embodiment of the present invention, a central mounting opening 203 is provided on the surface of the injection control plate 201, a guide slide 204 is provided above the central mounting opening 203, a horizontal screw 205 is rotatably provided below the central mounting opening 203 through an ear plate, the first meshing portion 202 is sleeved on the horizontal screw 205 and the two are threadedly matched, and a regulating gear 206 is fixedly installed at one end of the horizontal screw 205; the point switching mechanism 3 includes a point switching disk 301 rotatably provided inside the central mounting opening 203, and the point switching disk 301 is close to the first meshing portion 20 2 is fixedly provided with an outer tooth ring 302 coaxial with the outer tooth ring 302, which meshes with the first meshing portion 202 below it, and a rotation groove 303 is opened at the eccentric position of the point switching disk 301; through this structural design, when the control gear 206 is controlled to rotate, the horizontal screw 205 that rotates synchronously with the control gear 206 drives the first meshing portion 202 to slide horizontally along the surface of the injection control plate 201, thereby realizing the rotation of the outer tooth ring 302, thereby realizing the forward rotation or reverse rotation of the entire point switching mechanism 3.

[0038] In this embodiment of the present invention, the liquid storage mechanism 4 also includes a moving part 402 slidably arranged inside the guide slide 204, and moving platforms 403 fixedly connected to the moving part 402 are arranged on opposite sides of the injection control board 201.

Through this structural design, when the control point switching disk 301 rotates, the soil breaking and liquid injection assembly 6 can be driven to move synchronously with the point switching disk 301. In this process, the linkage control rod 610 slides longitudinally along the moving platform 403, and the moving platform 403 is driven to slide horizontally along the guide slide 204 through the movement of the linkage control rod 610, thereby realizing the synchronous movement between the bacterial liquid injection mechanism 5 and the liquid storage mechanism 4;

[0039] A first hydraulic cylinder 606 is installed on the top of the second support frame 605, and a lifting frame 607 connected to the output end of the first hydraulic cylinder 606 is slidably arranged inside the second support frame 605. The output end of the ground-breaking control motor 608 installed inside the lifting frame 607 is connected to the ground-breaking control shaft 609, and the lower end of the ground-breaking control shaft 609 passes through the bearing base 604 and is fixedly connected to the hollow ground-breaking rod 601; when the hollow ground-breaking rod 601 is pressed against the soil surface, the ground-breaking control motor 608 is started to drive the ground-breaking control shaft 609 to rotate, and the ground-breaking auger is driven by the rotation of the ground-breaking control shaft 609 602 rotates synchronously, and during this process, the first hydraulic cylinder 606 extends downward to make the ground-breaking control shaft 609 gradually move downward, thereby realizing that the ground-breaking auger piece 602 rotates while penetrating into the soil. After completing the ground-breaking and drilling a hole in the soil, the first hydraulic cylinder 606 retracts upward to make the ground-breaking control shaft 609 gradually move upward, and at the same time, the ground-breaking control motor 608 drives the ground-breaking control shaft 609 to rotate in the opposite direction, thereby making the ground-breaking auger piece 602 gradually rotate in the opposite direction and separate from the soil, until the entire hollow ground-breaking rod 601 and the ground-breaking auger piece 602 are completely pulled out of the soil.

[0040] In this embodiment of the present invention, the outer sleeve of the hollow guide plate 603 is provided with a rotating sealing ring 611 coaxial with the hollow guide plate 603, and a plurality of guide holes 612 are provided on the peripheral side of the rotating sealing ring 611. A guide tube corresponding to the guide holes 612 is fixedly provided between the hollow guide plate 603 and the rotating sealing ring 611, and one end of the guide tube is connected to the corresponding guide hole 612, and the other end of the guide tube is connected to the hollow guide plate 603. The inner wall of the hollow guide cover 701 is provided with an annular mounting opening 702 connected thereto, and the rotating sealing ring 611 is rotatably installed inside the annular mounting opening 702. Through the above-mentioned specific structural design, the rotation of the hollow guide plate 603 inside the hollow guide cover 701 can be guaranteed, and the hollow guide cover 701 can be driven to move synchronously when the hollow guide plate 603 is controlled to move up and down.

[0041] In this embodiment of the present invention, the bacterial liquid diversion assembly 7 also includes an L-shaped guide rod 703 fixedly arranged on the corresponding moving platform 403, and a first mounting seat 704 fixedly connected to the hollow guide cover 701 is slidably sleeved on the L-shaped guide rod 703. A second mounting seat 705 that is attached to the top of the hollow guide cover 701 is fixedly installed on the side surface of the hollow earth-breaking rod 601, and a lifting control motor 706 is installed on the top of the second mounting seat 705 through a motor seat. The output shaft of the lifting control motor 706 is connected to a rope winding wheel 707. The traction rope wound on the rope winding wheel 707 passes through the rope threading hole 613 on the hollow earth-breaking rod 601 and is fixedly connected to the piston liquid pressing part. After starting the lifting control motor 706, the traction rope can be wound or released by rotating the rope winding wheel 707, thereby enabling the piston liquid pressing part to move up and down inside the hollow earth-breaking rod 601 through the traction rope.

[0042] In this embodiment of the present invention, the bacterial liquid transfer unit includes a bacterial liquid transfer box 708 fixedly mounted on the top of the first mounting seat 704, a liquid outlet pipe 709 is installed on the side of the bacterial liquid transfer box 708 close to the bottom, one end of the liquid outlet pipe 709 penetrates into the hollow flow guide cover 701, a liquid inlet pipe 710 is fixedly mounted on the top of the bacterial liquid transfer box 708, and a solenoid valve 711 is installed on the side of the liquid inlet pipe 710. The bacterial liquid storage box 401 and the liquid inlet pipes 710 on both sides are connected by self-flow hoses; when the electric current is turned on, the liquid inlet pipe 710 is connected to the bacterial liquid storage box 401 by the ... When the magnetic valve 711 is turned on, the microbial liquid in the high-position liquid storage box 401 can flow downward along the gravity hose into the liquid transfer box 708. After a certain amount of microbial liquid is transported to the inside of the liquid transfer box 708, the electromagnetic valve 711 is closed, so that the microbial liquid that flows into the hollow guide cover 701 along the liquid outlet pipe 709 flows by gravity into the hollow guide plate 603, and finally flows into the hollow soil-breaking rod 601 and flows out along the various discharge ports thereon to a specified depth of the soil.

[0043] In the initial state, the bacterial liquid injection mechanism 5 on the opposite sides of the injection control plate 201 is at the highest position of the point switching disk 301, and the lower ends of the hollow soil-breaking rod 601 and the soil-breaking auger piece 602 are close to the bottom of the injection control plate 201 (to ensure that the hollow soil-breaking rod 601 and the soil-breaking auger piece 602 on the bacterial liquid injection mechanism 5 will not hinder the movement of the microorganism injection structure 1 during the movement of the entire microorganism injection structure 1), and each discharge port on the hollow soil-breaking rod 601 is blocked by the piston pressure liquid part (to ensure that soil particles will not enter the hollow soil-breaking rod 601 along the discharge port during the drilling process);

[0044] The control gear 206 is controlled to rotate, and the horizontal screw 205 that rotates synchronously with the control gear 206 drives the first meshing portion 202 to slide horizontally to the right along the surface of the injection control plate 201 until the first meshing portion 202 moves horizontally to Figure 2 In this process, the first meshing portion 202 drives the outer gear ring 302 to rotate counterclockwise, so that the entire point switching mechanism 3 rotates 90° counterclockwise. At this time, the bacterial liquid injection mechanisms 5 on the opposite sides of the injection control plate 201 move counterclockwise to Figure 2 In the position shown, the lower ends of the hollow earth-breaking rod 601 and the earth-breaking auger piece 602 move downward to be close to the soil surface (in this process, the moving platform 403 is driven to slide horizontally to the left along the guide slide 204 by the left movement of the linkage control rod 610, and the first mounting seat 704 slides downward along the L-shaped guide rod 703);

[0045] Next, the ground-breaking control motor 608 is started by the controller to drive the ground-breaking control shaft 609 to rotate, and the ground-breaking auger piece 602 is driven to rotate synchronously through the rotation of the ground-breaking control shaft 609. In this process, the ground-breaking control shaft 609 is gradually moved downward by the downward extension of the first hydraulic cylinder 606, so that the ground-breaking auger piece 602 can rotate while penetrating into the soil. After the ground-breaking and drilling of the soil hole is completed (the lower end of the ground-breaking control shaft 609 penetrates to the specified depth), the controller simultaneously turns off the ground-breaking control motor 608 and the first hydraulic cylinder 606, and starts the lifting control motor 706 to drive the rope winding wheel 707 to rotate. The rotation of the rope winding wheel 707 causes the traction rope to be gradually wound up until the piston pressure liquid part is lifted to the inside of the hollow guide plate 603 by the traction rope, and at this time the lifting control motor 706 is turned off by the controller;

[0046] Subsequently, the solenoid valve 711 is opened by the controller, so that the microbial bacterial liquid in the bacterial liquid storage box 401 at the high position flows downward along the gravity hose into the bacterial liquid transfer box 708. After a certain amount of microbial bacterial liquid is transported to the interior of the bacterial liquid transfer box 708, the solenoid valve 711 is closed, so that the microbial bacterial liquid flowing into the hollow guide cover 701 along the liquid outlet pipe 709 flows by gravity into the hollow guide plate 603 (specifically, the microbial bacterial liquid entering the hollow guide cover 701 successively passes through the guide hole 612 and the guide pipe and flows into the hollow guide plate 603), and then flows by gravity from the hollow guide plate 603 into the hollow earth-breaking rod 601. Since the soil in each discharge port will be filled with soil during the drilling process, The soil particles are blocked, so that the microbial liquid flowing into the hollow soil-breaking rod 601 is temporarily stored in the hollow soil-breaking rod 601, and the lifting control motor 706 is started again by the controller. The traction rope is gradually released through the reverse rotation of the rope winding wheel 707, and the piston liquid pressing part gradually moves downward along the hollow soil-breaking rod 601 until each discharge port is blocked again (the piston liquid pressing part has a certain weight to serve the purpose of counterweight). In this process, the microbial liquid in the hollow soil-breaking rod 601 is pressurized by the downward moving piston liquid pressing part, and the pressurized microbial liquid impacts each discharge port and is dispersed to the specified depth of the soil, thereby realizing the injection of the microbial liquid at the specified depth of the soil.

[0047] Next, the first hydraulic cylinder 606 is retracted upward to gradually move the soil-breaking control shaft 609 upward, and at the same time, the soil-breaking control shaft 609 is driven by the soil-breaking control motor 608 to rotate in the opposite direction, so that the soil-breaking auger piece 602 gradually rotates in the opposite direction and separates from the soil, until the entire hollow soil-breaking rod 601 and the soil-breaking auger piece 602 are completely pulled out of the soil (that is, the entire bacterial liquid injection mechanism 5 is returned to the bottom of the soil-breaking auger piece 602). Figure 2The control gear 206 is then controlled to rotate in the opposite direction, and the horizontal screw 205 that rotates in the opposite direction synchronously with the control gear 206 drives the first meshing portion 202 to slide horizontally to the left along the surface of the injection control plate 201 and return to the initial position. At this time, the bacterial liquid injection mechanisms 5 on the opposite sides of the injection control plate 201 rotate 90° in the clockwise direction, so that the bacterial liquid injection mechanisms 5 return to the highest position of the point switching disk 301 (in this process, the movable platform 403 is driven to slide horizontally to the right along the guide slide 204 through the rightward movement of the linkage control rod 610, and the first mounting seat 704 slides upward along the L-shaped guide rod 703);

[0048] Next, the control gear 206 is controlled to rotate in the opposite direction, and the first meshing portion 202 that continues to move to the left drives the outer gear ring 302 to rotate 90° clockwise. At this time, the bacterial liquid injection mechanisms 5 on both sides of the injection control board 201 move in the clockwise direction to Figure 2 In the relative position of the microbial solution injection mechanism 5 (in this process, the rightward movement of the linkage control rod 610 drives the movable platform 403 to slide horizontally to the right along the guide slide 204, and the first mounting seat 704 slides downward along the L-shaped guide rod 703), the lower end of the hollow soil-breaking rod 601 and the soil-breaking auger piece 602 moves downward to be close to the soil surface, and then the same soil drilling and liquid injection method is used to achieve the injection of the microbial solution at the specified depth of the soil at this position. After the injection of the microbial solution at the specified depth of the soil at this position is completed, the controller is used again to control the gear. 206 rotates, so that the first meshing portion 202 slides horizontally to the right along the surface of the injection control plate 201, so that the counterclockwise rotating point switching disk 301 drives the bacterial liquid injection mechanism 5 to return to the highest position of the point switching disk 301 in the counterclockwise direction (in this process, the movable platform 403 is driven to slide horizontally to the left along the guide slide 204 through the left movement of the linkage control rod 610, and the first mounting seat 704 slides upward along the L-shaped guide rod 703). In this way, the microbial bacterial liquid is injected into the soil at two adjacent points through the microbial injection structure 1.

[0050] When the second hydraulic cylinder 804 is activated by the controller, the second engaging portion 803 moves horizontally to the right along the limiting groove 802 (such as Figure 1 As shown in FIG. 1 ), the horizontally moving second meshing portion 803 drives each regulating gear 206 to rotate synchronously. When the second meshing portion 803 moves to Figure 1 When the position is in the position shown, the point switching disk 301 on each microorganism injection structure 1 is simultaneously rotated 90° counterclockwise, so that the bacterial liquid injection mechanism 5 on each microorganism injection structure 1 is rotated 90° counterclockwise. At this time, each bacterial liquid injection mechanism 5 is in Figure 1 When the second hydraulic cylinder 804 is activated by the controller to make the second meshing portion 803 move horizontally to the left along the limiting groove 802 to the initial position (that is, the second meshing portion 803 is in the middle of the limiting groove 802), each of the bacterial liquid injection mechanisms 5 at this time rotates 90° clockwise to return to the highest position of the point switching disk 301. When the second hydraulic cylinder 804 is activated by the controller again to make the second meshing portion 803 move horizontally to the left along the limiting groove 802, each of the bacterial liquid injection mechanisms 5 moves again in the clockwise direction to Figure 2 In the relative position of the bacterial solution injection mechanism 5, when the microbial bacterial solution injection operation in one area of ​​the soil is completed, the second engaging portion 803 is continuously moved horizontally to the right along the limiting groove 802 to the initial position (i.e., the middle position of the limiting groove 802) through the second hydraulic cylinder 804. At this time, each bacterial solution injection mechanism 5 returns to the initial position (i.e., the highest position of the point switching disk 301) in the counterclockwise direction. Then, the entire second injection control mechanism 8 and each microbial injection structure 1 thereon are moved to the next soil area by moving the vehicle body, and the microbial bacterial solution injection operation can be performed again.
