[0034] Inside the soil composition detection device, the motor lead screw 7 drives the first slider 8 to insert the soil composition detection probe 5 into the soil. The soil detection sensor located inside the soil composition detection probe 5 detects soil parameters and returns the detected soil parameters such as nitrogen, phosphorus, potassium, pH value, and humidity to the controller STM32F103 connected to the soil detection sensor. The controller STM32F103's built-in program processes the data, determines the remediation plan, and displays the soil parameters and remediation plan (powder and liquid concentration and ratio) on the serial port screen display interface that transmits data with the controller STM32F103 via the cloud. When spraying the pesticide solution in a quantitative ratio, the solenoid valve 34 and electromagnetic flow meter 33 in the solution mixing spraying device quantitatively mix the pesticide solution in the pesticide tank 31 according to the remediation plan. Then, the stirring rod 37 driven by the second DC motor 36 is stirred thoroughly, the water pump 45 draws the pesticide solution, and the adjustable mist nozzle 44 sprays the pesticide solution evenly. At the same time, the drive wheel 3 in the walking device drives the track 2 to make the farmland soil remediation trolley move at a constant speed. During the movement, the first DC motor 22 in the spreading mechanism drives the meshing roller 11 to crush the pesticide block into pesticide powder. At the same time, it drives the auger roller 12 to make the pesticide powder move effectively. The material leakage plate 26 installed at the bottom of the vehicle body changes the overlapping area of ​​the material leakage plate 26 by moving the slide rail 24 to control the amount of pesticide powder discharged by the spreading mechanism. At the same time, the plow blade 27 installed at the bottom of the vehicle body is also breaking the soil, enhancing the pesticide powder spreading effect and achieving the purpose of intelligent soil remediation.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
