The bottom end of the support plate 18 supports the telescopic rod 19, which runs smoothly. The bottom end of the telescopic rod 19 is connected to the water distribution pipe 21. The extension and retraction of the telescopic rod 19 drives the bottom water distribution pipe 21 to adjust its height up and down. The telescopic rod 19 adopts a standard electric push rod, model: TIEGEAR EG-500, whose built-in stepper motor is connected to the controller 10 through an RS485 interface. The controller 10 sends Modbus protocol commands to control the extension and retraction. The potentiometer inside the push rod provides real-time feedback of the position signal with an accuracy of ±1.5%. The bottom of the water distribution pipe 21 is fixed to the spray nozzle 22. Water is transmitted to the storage tank 14 through the water inlet 15. The submersible pump 16 operates to pump water and transmits it to the inside of the transmission pipe 17. The transmission pipe 17 transmits water to the inside of the control valve 20. The control valve 20 controls the water transmission and transmits water to the inside of the water distribution pipe 21, allowing the user to control the transmission volume. The water distribution pipe 21 transmits water to the inside of the spray nozzle 22. The inside of the spray nozzle 22 is pressurized, and the pesticide is sprayed onto the soil, where it neutralizes the components in the soil.

[0027] The spray nozzle 22 is a hollow cone-shaped atomizing nozzle. When the pressure of the liquid is ≥0.3MPa, the liquid is centrifugally atomized through the internal spiral groove, and the atomized particle size is 80~120μm.

The rotation of the transmission belt 5 drives the transmission wheel 4 to rotate. The rotation of the transmission wheel 4 drives the inner rotating shaft 3 to rotate. The rotating shaft 3 drives the two end moving wheels 8 to rotate. The rotation of the moving wheels 8 drives the device to move.

[0031] During the movement of the device, the steering motor 30 runs and drives the output end connecting rod to rotate. The rotation of the connecting rod drives the front set of bearing seats 2 at the bottom to adjust the angle. The front set of bearing seats 2 drives the front set of moving wheels 8 to adjust the angle, which facilitates the steering of the device.

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The mobile station 1 has a housing 9 installed on its top. A GPS module 31 is installed on one side of the housing 9. A photovoltaic panel 29 is installed on the top of the housing 9. A controller 10 is installed through the rear wall of the housing 9. A battery 11 is installed inside the housing 9.

[0033] The mobile platform 1 is fixed to the top housing 9 to ensure the stability of the housing 9. The housing 9 is fixed to the top photovoltaic panel 29 to ensure the stability of the photovoltaic panel 29. When sunlight shines on the photovoltaic panel 29, the photovoltaic panel 29 converts light energy into electrical energy. The current is transmitted to the inside of the storage battery 11 through the photovoltaic controller 13. The storage battery 11 stores electricity. When the storage battery 11 outputs power, the photovoltaic controller 13 controls the current output inside the storage battery 11. The inverter 12 converts DC power into AC power to improve the power of the electrical equipment.

[0034] The photovoltaic controller 13 uses the EPeverTracer 4215BN, and its load output priority is as follows: 1. Submersible pump 16 DC power supply 24VDC → 2. Motor 26 DC power supply → 3. Inverter 12 AC output 220VAC to control motor 6.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The mobile platform 1 is equipped with fixed platforms 23 on both sides. An electric adjusting rod 24 is installed through the inner side of the fixed platform 23. A lifting plate 25 is installed at the bottom end of the electric adjusting rod 24. A pressure sensor 32 is installed at the bottom end of the electric adjusting rod 24. The lifting plate 25 is installed at the bottom end of the pressure sensor 32. A rotating shaft 27 is installed on the inner side of the lifting plate 25. A turning blade 28 is installed on the outer side of the rotating shaft 27. A grass scraper 33 is installed at one end of the turning blade 28. A motor 26 is installed on one side of the lifting plate 25. The output end of the motor 26 is connected to the rotating shaft 27.

[0036] Pressure sensor 32 is connected to controller 10 via leads;

[0037] The mobile platform 1 is fixed to the fixed platforms 23 on both sides to ensure the stability of the fixed platforms 23. The fixed platforms 23 are fixed to the inner electric adjustment rod 24 to ensure the smooth operation of the electric adjustment rod 24. The extension and retraction of the electric adjustment rod 24 drives the bottom lifting plate 25 to adjust its height up and down. The lifting plate 25 drives the rotating shaft 27 and the turning blade 28 to adjust their height up and down, so that the turning blade 28 can penetrate into the soil.

[0038] The motor 26 drives the output shaft 27 to rotate, and the rotation of the shaft 27 drives the outer turning blade 28 to rotate. The rotation of the turning blade 28 turns the soil, causing the pesticide solution on the soil to be buried underground, thereby achieving soil pollution treatment and improving the treatment effect.

[0039] Timing control of tilling and spraying

[0040] Controller 10 is configured with two operating modes:

[0041] Mode 1: Spraying complete → Delay for 10 seconds to allow the pesticide to penetrate → Start tilling;

[0042] Mode 2: The interval between spraying and tilling areas is ≥0.5m, which is ensured by a moving speed of 0.3m / s to avoid component interference.

[0043] Working principle: The control motor 6 drives the output end drive wheel 7 to rotate. The rotation of the drive wheel 7 drives the outer transmission belt 5 to rotate. The rotation of the transmission belt 5 drives the transmission wheel 4 to rotate. The rotation of the transmission wheel 4 drives the inner rotating shaft 3 to rotate. The rotating shaft 3 drives the two end moving wheels 8 to rotate. The rotation of the moving wheels 8 drives the device to move. The electric adjusting rod 24 extends and drives the bottom lifting plate 25 to adjust its height downward. The lifting plate 25 drives the rotating shaft 27 and the turning blade 28 to adjust their height, so that the turning blade 28 penetrates into the soil. The motor 26 drives the output end rotating shaft 27 to rotate. The rotating shaft 27 drives the outer turning blade 28 to rotate. The turning blade 28 turns the soil, burying the medicine on the soil underground. The helix angle of the turning blade 28 is 35°±2°. The blade surface is laser hardened to a hardness of HRC58-62. The electric adjusting rod 24 automatically stops when the soil resistance is ≥200N, and the pressure sensor provides feedback to ensure a burial depth of 20±2cm, thus achieving soil pollution remediation. The bottom end of the telescopic rod 19 is connected to the water distribution pipe 21. The extension and retraction of the telescopic rod 19 adjusts the height of the water distribution pipe 21. The bottom of the water distribution pipe 21 is fixed to the spray nozzle 22. Water is transmitted to the storage tank 14 through the water inlet 15. The submersible pump 16 operates to pump water and transmit it to the inside of the transmission pipe 17. Water is transferred from the transmission pipe 17 to the inside of the control valve 20. The control valve 20 controls the water transfer, which in turn transfers the water to the inside of the distribution pipe 21. The distribution pipe 21 then transfers the water to the inside of the spray nozzle 22, where pressurization occurs, spraying the pesticide onto the soil. The pesticide neutralizes the components in the soil. A 0.1 mol / L citric acid solution is injected into the storage tank 14. The control valve 20 adjusts the flow rate to 5–20 L / min with an accuracy of ±2%. The pesticide reacts with lead ions: Pb 2+ +2C6H8O7→Pb(C6H7O7)2↓+2H + After treatment, the lead content in the soil decreased from 850 mg / kg to 120 mg / kg.
