Remediation agent anti-precipitation spraying device for soil remediation

The invention discloses a remediation agent anti-precipitation spraying device for soil remediation. The remediation agent anti-precipitation spraying device comprises a base, a box body, a supporting plate, a stirring shaft, a stirring rod, an end face gear, a transmission gear, a rotating shaft, a bearing, a first belt wheel, a belt, a second belt wheel, a motor, a disc, a connecting rod, a mounting plate, a fixing rod, a placement plate, a pressing plate, a limiting plate, a bolt, a pump body, a water inlet pipe, a water outlet pipe, a spray head, a shell, a roller and a vertical rod. The device is simple in structure, and a repairing agent is continuously stirred at the bottom of the box body, so that the problem of nonuniform concentration of the repairing agent caused by precipitation of the repairing agent due to long-time standing is avoided; a spray head can be driven to vertically swing back and forth during stirring, so that the spraying area of the spray head is conveniently increased, and the pro
