The invention discloses an argillization type soil remediation device. The argillization type soil remediation device comprises a machining box; a base is arranged below the machining box, and the left side and the right side of the base are provided with rolling wheels for allowing the device to be transferred conveniently; the two sides of the lower end of the machining box are symmetrically provided with supporting legs, and the lower ends of the supporting legs are slidably sleeved with supporting sleeves; buffer springs are arranged in the supporting sleeve, and the supporting sleeves andthe supporting legs are connected and fixed through the buffer springs; the lower ends of the supporting sleeves and the base are connected and fixed, and the shock resistance of the argillization type soil remediation device is improved by effectively arranging the buffer mechanism; and a lifting barrel penetrates through the middle of the upper end of the machining box. The argillization type soil remediation device is simple and reasonable in structure, convenient to transfer and good in shock resistance, soil is subjected to argillization at first, then, insoluble impurities are removed,the soil is refined and dried, accordingly, the refining degree of the soil is ensured, and final disinfection remediation is conducted. Through the remediation mode, the defect that existing devicesare not good in smashing is overcome, the soil remediation effect is greatly improved, and the practicality is high.
