The invention belongs to the field of soil pollution remediation equipment, particularly relates to a vehicle-mounted mobile soil pollution robot sampling, detecting and remediation treatment vehicle, and aims to solve the problems that existing sampling, detecting and remediation treatment equipment is heavy in size, inconvenient to flexibly adjust the use position, difficult to remedy soil at different positions and low in remediation, detecting and remediation efficiency. According to the scheme, the vehicle-mounted mobile soil pollution robot sampling, detecting and remediation treatment vehicle comprises a treatment vehicle body, a mounting hole is formed in the top of the treatment vehicle body, a sampling box is fixedly mounted in the mounting hole, a moving platform is slidably mounted in the sampling box, a rotating hole is formed in the top of the moving platform, a soil expanding screw rod is rotatably mounted in the rotating hole, and a rotating hole is formed in the top end of the soil expanding screw rod. The vehicle-mounted mobile soil pollution robot sampling, detecting and remediation treatment vehicle is reasonable in structure and convenient to operate, the size is flexible, the use position can be conveniently and flexibly adjusted, soil at different positions can be repaired, rapid soil expanding and sampling can be achieved, and the repairing, detecting and remediation efficiency is high.
