Description

Technical Field

[0001] The present invention belongs to the technical field of environmental governance, and relates to a soil remediation device, in particular to a soil remediation device for environmental governance and a remediation operation method. Background Art

[0002] Environmental governance refers to the corresponding preventive and treatment measures taken for the pollution and damage of a series of major strategic resources such as land, water resources, and the atmosphere that have occurred or may occur during the development process of human society. In environmental governance, soil remediation is very important. Soil remediation is a technical measure to restore polluted soil to its normal function. Usually, physical, chemical, and biological methods are used to transfer, absorb, degrade, and transform pollutants in the soil, so that their concentration is reduced to an acceptable level, or toxic and harmful pollutants are transformed into harmless substances.

[0003] Existing soil remediation equipment generally only injects agents underground for on-site remediation. However, this injection method results in insufficient combination of the remediation agent and the soil, and the remediation effect is limited. It has a certain effect on soil with relatively light pollution, but for soil with relatively heavy pollution, the effect of this equipment is very limited.

[0004] After retrieval, a Chinese patent document discloses a soil remediation equipment for environmental governance [Application No.: 202210826941.5; Publication No.: CN115156269A]. This soil remediation equipment uses a soil adding mechanism to transport the soil to be remediated into a crushing barrel, uses a crushing mechanism in the crushing barrel to crush the soil, and the crushed soil is transported out of the crushing barrel by a soil output mechanism, and a remediation agent is sprayed on the soil to achieve the remediation of the soil. The soil remediation equipment for environmental governance provided by the present invention can control the depth of shoveling soil, and by crushing the soil to be remediated and then spraying the remediation agent, the soil and the remediation agent can be mixed more fully. Moreover, by spraying the remediation agent, it can be avoided that when the soil contacts a certain amount of the remediation agent, the soil becomes muddy, ensuring full contact between the remediation agent and the soil, and having a good remediation effect on soil with relatively light or heavy pollution.

[0005] Although the remediation device disclosed in this patent uses a soil adding mechanism to transport the soil to be remediated into a crushing barrel, uses a crushing mechanism in the crushing barrel to crush the soil, transports the crushed soil out of the crushing barrel by a soil output mechanism, and sprays a remediation agent on the soil to achieve the remediation of the soil, however, this device needs to dig out the soil for remediation, and after the remediation is completed, the soil needs to be restored to its original position, which has a large workload. And during the remediation process, the waste gas generated by the remediation cannot be collected and purified, causing environmental pollution and not meeting the environmental protection requirements. Summary of the Invention

[0006] The object of the present invention is to address the above problems existing in the prior art, and a soil remediation device and a remediation operation method for environmental governance are proposed. The technical problem to be solved by this invention is: how to achieve improving the soil remediation effect while ensuring the soil remediation efficiency, collecting and treating waste gas, and reducing environmental pollution.

[0007] The object of the present invention can be achieved by the following technical solutions: A soil remediation device for environmental governance, including a base, universal wheels are arranged on the lower side of the base, a box body is fixed on the upper side of the base, two liquid storage chambers, a mixing chamber and a purification chamber are arranged inside the box body. Both liquid storage chambers are communicated with the mixing chamber through a first liquid delivery pump. A lifting mechanism is arranged on the outside of the box body, and a closed cylinder is arranged on the lifting mechanism. A second liquid delivery pump is arranged in the mixing chamber, and the second liquid delivery pump is communicated with the closed cylinder through a pipeline. A remediation component is arranged inside the closed cylinder. The two liquid storage chambers are separated by a partition plate. A chute is opened at the upper end inside the box body, a first motor is fixed inside the chute, a first threaded rod is fixed at the output shaft end of the first motor, and the first threaded rod is threadedly connected with the partition plate. Several purification modules are arranged inside the purification chamber. A first electric telescopic rod is fixed at the lower end of the base, and a gas collection hood is fixed at the lower end of the electric telescopic rod. An air outlet seat is arranged inside the purification chamber, and the air outlet seat is communicated with the gas collection hood through a telescopic pipe.

[0008] The working principle of the present invention is: when remediating the soil, first use a detection device to detect the pollution degree of the soil, then mark the soil remediation area according to the pollution degree, and calculate the amount of medicine needed according to the area of the soil. Thus, drive the first threaded rod to rotate by the first motor, and then drive the partition plate to move left and right to adjust the sizes of the two liquid storage chambers. The left liquid storage chamber contains medicine with a lower concentration, and the right liquid storage chamber contains medicine with a higher concentration. The ratio of the low-concentration medicine and the high-concentration medicine can be adjusted according to the pollution degree of the area to be remediated. After moving the device to the land to be remediated, according to the mark, send the low-concentration medicine and the high-concentration medicine into the mixing chamber for mixing. At the same time, use the lifting mechanism to send the closed cylinder and the remediation component into the ground, and then use the second liquid delivery pump to send the mixed medicine into the soil to modify the soil, and the concentration of the medicine can be adjusted according to the pollution degree. Use low-concentration medicine for low-pollution areas and high-concentration medicine for high-pollution areas, so that resources can be fully utilized. After the medicine is sent in, the device moves forward to remediate the next piece of soil. At the same time, cover the gas collection hood on the already remediated soil, so that the gas generated by the medicine and soil pollutants enters the purification chamber for purification and then is discharged to prevent air pollution.

[0009] The lifting mechanism includes a lifting seat, which is fixedly connected to the box body. A second motor is fixed on the lifting seat. A second threaded rod is fixed to the output shaft end of the second motor. A lifting plate is threadedly connected to the second threaded rod. A second electric telescopic rod is fixed on the lifting plate. The telescopic end of the second electric telescopic rod is fixedly connected to the closed cylinder.

[0010] With the above structure, when repairing the soil, first use the second motor to drive the second threaded rod to rotate, so that the lifting plate drives the closed cylinder to descend, making the closed cylinder enter the ground, and then use the second electric telescopic rod to finely adjust the position of the closed cylinder to ensure the accuracy of the repair depth.

[0011] A third motor is fixed on the box body. The output shaft end of the third motor is fixed with a stirring shaft extending into the mixing cavity. A number of stirring blades are fixed on the stirring shaft. Both the stirring shaft and the stirring blades are hollow structures and are interconnected. A number of liquid spraying ports are opened on the stirring blades. The liquid outlet end of the first liquid delivery pump is fixed with a liquid delivery cover. The liquid delivery cover is sleeved on the stirring shaft and is rotatably connected to the stirring shaft. The liquid delivery cover is internally connected to the stirring shaft.

[0012] With the above mechanism, when transporting two concentrations of liquid medicine, the liquid medicine enters the stirring shaft and then sprays out from the liquid spraying ports on the stirring blades. At the same time, start the third motor, and the third motor drives the stirring shaft and the stirring blades to rotate, realizing the stirring while spraying the liquid medicine and improving the mixing efficiency of the liquid medicine.

[0013] Stabilizing mechanisms are arranged in both of the two liquid storage cavities. The stabilizing mechanism includes a first buoyancy plate and a second buoyancy plate. A sliding cavity is opened inside the first buoyancy plate. A first spring is fixed inside the sliding cavity. The second buoyancy plate extends into the sliding cavity and is fixedly connected to the first spring. A number of liquid outlet ports are opened on the second buoyancy plate. A sliding groove is opened on the lower side of the second buoyancy plate. A number of stabilizing plates are fixed on the lower side of the first buoyancy plate. A number of stabilizing plates are slidably connected inside the sliding groove. A second spring is fixed between adjacent stabilizing plates.

[0014] With the above structure, when the device is moving, the cooperation of the first buoyancy plate, the second buoyancy plate and the stabilizing plates can be used to slow down the shaking of the liquid medicine, thereby reducing the impact on the device caused by the shaking of the liquid medicine when the device is moving, and the device can be protected. At the same time, the setting of the first spring and the second spring can not only improve the stabilizing effect on the liquid medicine, but also enable the stabilizing mechanism to be adaptively adjusted along with the size of the liquid storage cavity when the partition plate adjusts its position, ensuring the stability of the device.

[0015] A number of flow slowing ports are opened on the stabilizing plates. The flow slowing ports are all conical structures, and the conical directions of adjacent flow slowing ports are opposite.

[0016] With the above structure, not only can the slow-flow port be used to improve the stabilization effect on the liquid medicine, but also after the liquid medicine flows through the slow-flow port, the flow rate can be changed, thereby realizing the perturbation of the liquid medicine, ensuring the uniformity of the liquid medicine in the liquid storage cavity, and reducing the generation of precipitation.

[0017] An annular liquid delivery cavity is provided on the inner wall of the closed cylinder. Liquid delivery ports are provided on the inner circumference of the annular liquid delivery cavity. A rotating cylinder is rotatably connected inside the closed cylinder. A number of liquid outlet grooves cooperating with the liquid delivery ports are provided on the rotating cylinder. A fourth motor is fixed inside the closed cylinder. A driving gear is fixed to the output shaft end of the fourth motor. A driven gear ring is fixed to the inner circumference of the rotating cylinder. The driven gear ring meshes with the driving gear.

[0018] With the above structure, when the closed cylinder enters the ground, the liquid outlet grooves of the rotating cylinder are staggered with the positions of the liquid delivery ports. When it is necessary to deliver the liquid medicine, the fourth motor drives the driving gear to rotate. The driving gear drives the rotating cylinder to rotate through the driven gear ring, so that the positions of the liquid delivery ports and the liquid outlet grooves correspond, so that the liquid medicine enters the soil and is mixed with the soil to realize the repair of the soil. This structure can prevent the soil from blocking the liquid delivery ports and affecting the normal operation of the device.

[0019] A number of empty grooves are provided inside the rotating cylinder. A third spring is fixed inside the empty grooves. The other end of the third spring is fixed with an arc-shaped protrusion. The arc-shaped protrusion extends out of the rotating cylinder. The diameter of the arc-shaped protrusion is smaller than the diameter of the liquid delivery port, and the position of the arc-shaped protrusion corresponds to the position of the liquid delivery port.

[0020] With the above structure, during operation, the arc-shaped protrusions can enter the liquid delivery ports intermittently through the rotation of the rotating cylinder, so as to clean and dredge the liquid delivery ports by the ejection of the arc-shaped protrusions, so that the liquid delivery ports can always remain unobstructed and improve the stability of liquid delivery.

[0021] The repair assembly includes a fifth motor fixed inside the closed cylinder. A stirring column is fixed to the output shaft end of the fifth motor. A driving cavity is provided inside the stirring column. A sixth motor is fixed inside the driving cavity. A third threaded rod is fixed to the output shaft end of the sixth motor. A number of adjusting seats are threadedly connected to the third threaded rod. A number of extension ports are provided on the outer circumference of the stirring column. A support shaft is slidably connected to the extension ports. A second crushing blade is fixed to the outer circumference of the support shaft. A seventh motor is fixed inside the support shaft. A rotating shaft is fixed to the output shaft end of the seventh motor. The rotating shaft is rotatably connected to the support shaft. A number of first crushing blades are fixed to the support shaft. A connecting seat is fixed to the other end of the support shaft. A driving rod is hinged between the connecting seat and the adjusting seat.

[0022] With the above structure, when the mixing column enters the soil, the first crushing blade is located inside the mixing column to prevent damage to the first crushing blade by the soil during the entry process. After the mixing shaft completely enters, the sixth motor drives the third threaded rod to rotate, so that the adjusting seat moves up and down. Under the action of the driving rod, the support shaft and the rotating shaft extend. Then, the fifth motor and the seventh motor are turned on, so that the first crushing blade rotates and revolves at the same time, thereby stirring and crushing the soil, improving the mixing effect of the soil and the liquid medicine. The setting of the second crushing blade can block the outlet opening with the second crushing blade after the first crushing blade extends, thereby preventing the soil from entering the driving cavity and damaging the device.

[0023] A soil remediation operation method for environmental governance includes the following steps: S1. Use a detection device to detect the area of the soil to be remediated multiple times, and divide and mark the soil area according to the pollution degree; S2. Calculate the ratio of the low-concentration drug and the high-concentration drug to be used according to the pollution degree of the land. Then, after adjusting the position of the partition board according to the calculated ratio, send the low-concentration drug and the high-concentration drug into the corresponding liquid storage cavities; S3. After moving the soil remediation device to the area of the soil to be remediated, insert the closed cylinder and the mixing column below the ground, and at the same time send the low-concentration drug and the high-concentration drug into the mixing cavity for mixing according to the comparison; S4. Turn on the second liquid delivery pump to send the mixed liquid medicine into the closed cylinder and spray it out. At the same time, turn on the fifth motor and the seventh motor, so that the first crushing blade rotates and revolves at the same time, crush and stir the soil, and mix the liquid medicine with the soil; S5. After mixing is completed, pull out the closed cylinder and the mixing column from the ground, move the device forward to repair the next area. At the same time, cover the gas collection hood on the already repaired soil, so that the gas generated by the medicine and the soil pollutants enters the purification cavity for purification and then is discharged.

[0024] Compared with the prior art, the soil remediation device and the remediation operation method for environmental governance of the present invention have the following advantages: 1. When repairing the soil, first use the detection device to detect the pollution degree of the soil, then mark the repair area of the soil according to the pollution degree, and calculate the amount of medicine needed according to the area of the soil. Then drive the first threaded rod to rotate by the first motor, so as to drive the partition plate to move left and right, adjust the sizes of the two liquid storage cavities. The left liquid storage cavity contains the medicine with a lower concentration, and the right liquid storage cavity contains the medicine with a higher concentration. The ratio of the low-concentration medicine and the high-concentration medicine can be adjusted according to the pollution degree of the area to be repaired. After moving the device to the land to be repaired, according to the mark, send the low-concentration medicine and the high-concentration medicine into the mixing cavity for mixing. At the same time, use the lifting mechanism to send the closed cylinder and the repair component into the ground, and then use the second liquid delivery pump to send the mixed medicine into the soil to modify the soil. And the concentration of the medicine can be adjusted according to the pollution degree. Use the low-concentration medicine for low-pollution areas and the high-concentration medicine for high-pollution areas, so that resources can be fully utilized. After the medicine is sent in, the device moves forward to repair the next piece of soil. At the same time, cover the air hood on the repaired soil, so that the gas generated by the medicine and the soil pollutants enters the purification cavity for purification and then is discharged to prevent air pollution.

[0025] 2. When transporting the liquid medicine of two concentrations, the liquid medicine enters the stirring shaft and then sprays out from the liquid spraying ports on the stirring blades. At the same time, start the third motor, and the third motor drives the stirring shaft and the stirring blades to rotate, realizing spraying and stirring of the liquid medicine at the same time, and improving the mixing efficiency of the liquid medicine.

[0026] 3. The cooperation of the first buoyancy plate, the second buoyancy plate and the stabilizing plate can be used to slow down the shaking of the liquid medicine, so as to reduce the impact of the shaking of the liquid medicine on the device when the device moves, and the device can be protected. At the same time, the setting of the first spring and the second spring can not only improve the stabilizing effect of the liquid medicine, but also enable the stabilizing mechanism to be adjusted adaptively with the size of the liquid storage cavity when the partition plate adjusts its position, ensuring the stability of the device.

[0027] 4. When the closed cylinder enters the ground, the liquid outlet groove of the rotating cylinder is staggered from the liquid delivery port. When the liquid medicine needs to be transported, drive the driving gear to rotate by the fourth motor, and the driving gear drives the rotating cylinder to rotate through the driven tooth ring, so that the positions of the liquid delivery port and the liquid outlet groove correspond, so that the liquid medicine enters the soil and is mixed with the soil to realize the repair of the soil. This structure can prevent the soil from blocking the liquid delivery port and affecting the normal operation of the device.

[0028] 5. When the mixing column enters the soil, the first crushing blade is located inside the mixing column to prevent damage to the first crushing blade by the soil during the entry process. After the mixing shaft completely enters, the sixth motor drives the third threaded rod to rotate, thereby causing the adjustment seat to rise and fall. Under the action of the driving rod, the support shaft and the rotating shaft extend. Then, the fifth motor and the seventh motor are turned on, causing the first crushing blade to rotate while revolving, thereby stirring and crushing the soil to improve the mixing effect of the soil and the liquid medicine. The setting of the second crushing blade can block the outlet after the first crushing blade extends, thereby preventing the soil from entering the driving cavity and damaging the device.

Detailed implementation manners

[0038] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0039] As Figures 1-8 shown, the soil remediation device for environmental governance includes a base 1. Universal wheels are arranged on the lower side of the base 1, and a box body 2 is fixed on the upper side of the base 1. Two liquid storage cavities 3, a mixing cavity 4 and a purification cavity 5 are arranged inside the box body 2. Both liquid storage cavities 3 are communicated with the mixing cavity 4 through a first liquid delivery pump 19. A lifting mechanism is arranged on the outside of the box body 2, and a closed cylinder 15 is arranged on the lifting mechanism. A second liquid delivery pump is arranged in the mixing cavity 4, and the second liquid delivery pump is communicated with the closed cylinder 15 through a pipeline. A repair component is arranged inside the closed cylinder 15. The two liquid storage cavities 3 are separated by a partition plate. A chute 24 is opened at the upper end inside the box body 2, and a first motor 52 is fixed inside the chute 24. A first threaded rod 53 is fixed at the output shaft end of the first motor 52, and the first threaded rod 53 is threadedly connected with the partition plate. Several purification modules 6 are arranged inside the purification cavity 5. A first electric telescopic rod 7 is fixed at the lower end of the base 1, and a gas collecting hood 8 is fixed at the lower end of the electric telescopic rod. An air outlet seat 9 is arranged inside the purification cavity 5, and the air outlet seat 9 is communicated with the gas collecting hood 8 through a telescopic pipe.

[0040] When repairing the soil, first use the detection device to detect the pollution degree of the soil, then mark the repair area of the soil according to the pollution degree, and calculate the amount of medicine needed according to the area of the soil. Thus, drive the first threaded rod 53 to rotate by the first motor 52, so as to drive the partition plate to move left and right, adjust the size of the two liquid storage chambers 3. The left liquid storage chamber 3 contains the medicine with a lower concentration, and the right liquid storage chamber 3 contains the medicine with a higher concentration. The ratio of the low-concentration medicine and the high-concentration medicine can be adjusted according to the pollution degree of the area to be repaired. After moving the device to the land to be repaired, according to the mark, send the low-concentration medicine and the high-concentration medicine into the mixing chamber 4 for mixing. At the same time, use the lifting mechanism to send the closed cylinder 15 and the repair component into the ground, and then use the second liquid delivery pump to send the mixed medicine into the soil to modify the soil. And the concentration of the medicine can be adjusted according to the pollution degree. Use the low-concentration medicine for low pollution and the high-concentration medicine for high pollution, so that the resources can be fully utilized. After the medicine is sent in, the device moves forward to repair the next piece of soil. At the same time, cover the gas collecting hood 8 on the repaired soil, so that the gas generated by the medicine and the soil pollutants enters the purification chamber 5 for purification and then is discharged to prevent air pollution.

[0041] The lifting mechanism includes a lifting seat 10. The lifting seat 10 is fixedly connected to the box body 2. A second motor 11 is fixed on the lifting seat 10. A second threaded rod 12 is fixed to the output shaft end of the second motor 11. A lifting plate 13 is threadedly connected to the second threaded rod 12. A second electric telescopic rod 14 is fixed on the lifting plate 13. The telescopic end of the second electric telescopic rod 14 is fixedly connected to the closed cylinder 15.

[0042] Adopting the above structure, when repairing the soil, first drive the second threaded rod 12 to rotate by the second motor 11, so that the lifting plate 13 drives the closed cylinder 15 to descend, so that the closed cylinder 15 enters the ground, and then use the second electric telescopic rod 14 to finely adjust the position of the closed cylinder 15 to ensure the accuracy of the repair depth.

[0043] A third motor 16 is fixed on the box body 2. A stirring shaft 17 extending into the mixing chamber 4 is fixed to the output shaft end of the third motor 16. A number of stirring blades 18 are fixed on the stirring shaft 17. The stirring shaft 17 and the stirring blades 18 are both hollow structures and communicate with each other. A number of liquid spraying ports 29 are opened on the stirring blades 18. The liquid outlet end of the first liquid delivery pump 19 is fixed with a liquid delivery cover 28. The liquid delivery cover 28 is sleeved on the stirring shaft 17 and is rotatably connected to the stirring shaft 17. The liquid delivery cover 28 communicates with the inside of the stirring shaft 17.

[0044] With the above mechanism, when delivering liquid medicines of two concentrations, the liquid medicines enter the stirring shaft 17 and then are ejected from the liquid spraying ports 29 on the stirring blades 18. At the same time, the third motor 16 is started, and the third motor 16 drives the stirring shaft 17 and the stirring blades 18 to rotate, realizing spraying and stirring of the liquid medicines simultaneously, and improving the mixing efficiency of the liquid medicines.

[0045] Stabilizing mechanisms are arranged in both of the two liquid storage cavities 3. The stabilizing mechanism includes a first buoyancy plate 20 and a second buoyancy plate 21. A sliding cavity is formed inside the first buoyancy plate 20. A first spring 22 is fixed inside the sliding cavity. The second buoyancy plate 21 extends into the sliding cavity and is fixedly connected with the first spring 22. A plurality of liquid discharging ports 23 are formed on the second buoyancy plate 21. A sliding groove 24 is formed on the lower side of the second buoyancy plate 21. A plurality of stabilizing plates 26 are fixed on the lower side of the first buoyancy plate 20. A plurality of stabilizing plates 26 are slidably connected inside the sliding groove 24. A second spring 25 is fixed between adjacent stabilizing plates 26.

[0046] With the above structure, when the device moves, the cooperation of the first buoyancy plate 20, the second buoyancy plate 21 and the stabilizing plates 26 can be utilized to slow down the shaking of the liquid medicines, thereby reducing the impact of the shaking of the liquid medicines on the device when the device moves, and protecting the device can be realized. At the same time, the setting of the first spring 22 and the second spring 25 can not only improve the stabilizing effect on the liquid medicines, but also enable the stabilizing mechanism to be adaptively adjusted along with the size of the liquid storage cavity 3 when the partition plate adjusts its position, ensuring the stability of the device.

[0047] A plurality of flow buffering ports 27 are formed on the stabilizing plates 26. The flow buffering ports 27 are all of a conical structure, and the conical directions of adjacent flow buffering ports 27 are opposite.

[0048] With the above structure, not only can the flow buffering ports 27 be utilized to improve the stabilizing effect on the liquid medicines, but also after the liquid medicines flow through the flow buffering ports 27, the flow rate can be changed, thereby realizing the disturbance of the liquid medicines, enabling the liquid medicines in the liquid storage cavity 3 to ensure uniformity and reducing the generation of precipitation.

[0049] An annular liquid delivery cavity 35 is formed on the inner wall of the closed cylinder 15. Liquid delivery ports 36 are formed on the inner periphery of the annular liquid delivery cavity 35. A rotating cylinder 37 is rotatably connected inside the closed cylinder 15. A plurality of liquid outlet grooves 38 cooperating with the liquid delivery ports 36 are formed on the rotating cylinder 37. A fourth motor 47 is fixed inside the closed cylinder 15. A driving gear 48 is fixed at the output shaft end of the fourth motor 47. A driven gear ring 49 is fixed on the inner periphery of the rotating cylinder 37. The driven gear ring 49 meshes with the driving gear 48.

[0050] With the above structure, when the closed cylinder 15 enters the ground, the liquid outlet groove 38 of the rotating cylinder 37 is misaligned with the liquid delivery port 36. When it is necessary to transport the liquid medicine, the fourth motor 47 drives the driving gear 48 to rotate. The driving gear 48 drives the rotating cylinder 37 to rotate through the driven gear ring 49, so that the positions of the liquid delivery port 36 and the liquid outlet groove 38 correspond, so that the liquid medicine enters the soil and is mixed with the soil, realizing the repair of the soil. This structure can prevent the soil from blocking the liquid delivery port 36 and affecting the normal operation of the device.

[0051] A number of empty grooves are provided inside the rotating cylinder 37. A third spring 50 is fixed inside the empty groove. The other end of the third spring 50 is fixed with an arc-shaped protrusion 51. The arc-shaped protrusion 51 extends out of the rotating cylinder 37. The diameter of the arc-shaped protrusion 51 is smaller than the diameter of the liquid delivery port 36, and the position of the arc-shaped protrusion 51 corresponds to the position of the liquid delivery port 36.

[0052] With the above structure, during operation, the rotation of the rotating cylinder 37 can make the arc-shaped protrusion 51 intermittently enter the liquid delivery port 36, so as to clean and dredge the liquid delivery port 36 by the ejection of the arc-shaped protrusion 51, so that the liquid delivery port 36 can always remain unobstructed and improve the stability of liquid delivery.

[0053] The repair assembly includes a fifth motor 30 fixed inside the closed cylinder 15. A stirring column 31 is fixed at the output shaft end of the fifth motor 30. A driving cavity is provided inside the stirring column 31. A sixth motor 39 is fixed inside the driving cavity. A third threaded rod 40 is fixed at the output shaft end of the sixth motor 39. A number of adjusting seats 41 are threadedly connected to the third threaded rod 40. A number of extending ports 32 are provided on the outer periphery of the stirring column 31. A support shaft 43 is slidably connected to the extending port 32. A second crushing blade 46 is fixed on the outer periphery of the support shaft 43. A seventh motor 45 is fixed inside the support shaft 43. A rotating shaft 33 is fixed at the output shaft end of the seventh motor 45. The rotating shaft 33 is rotatably connected to the support shaft 43. A number of first crushing blades 34 are fixed on the support shaft 43. A connecting seat 44 is fixed at the other end of the support shaft 43. A driving rod 42 is hinged between the connecting seat 44 and the adjusting seat 41.

[0054] With the above structure, when the stirring column 31 enters the soil, the first crushing blade 34 is located inside the stirring column 31 to prevent damage to the first crushing blade 34 by the soil during the entry process. After the stirring shaft 17 completely enters, the sixth motor 39 drives the third threaded rod 40 to rotate, so that the adjusting seat 41 moves up and down. Under the action of the driving rod 42, the support shaft 43 and the rotating shaft 33 extend out. Then, the fifth motor 30 and the seventh motor 45 are turned on, so that the first crushing blade 34 rotates and revolves at the same time, thereby stirring and crushing the soil, improving the mixing effect of the soil and the liquid medicine.
