A chemical dispensing device for soil remediation

This utility model discloses a chemical injection device for soil remediation, comprising: a main body of the chemical injection device, including a device support, a chemical tank, a lifting frame, a drilling mechanism, and a control panel. The chemical tank is located at the top of the device support, the lifting frame is located in the middle of the device support, and the drilling mechanism is installed at the upper end of the lifting frame. The drilling mechanism includes a transmission box, a drive motor, and a drill rod. It can solve the problems of inconsistent depth detection and layered chemical injection: traditional equipment relies on manual measurement of drilling depth, which cannot dynamically adjust the injection position in real time, resulting in uneven chemical distribution; the problem of injection hole clogging is prominent: soil backfilling or loose particles after drilling can easily cause the injection hole to collapse and clog, requiring repeated hole cleaning or even secondary drilling, which greatly reduces the work efficiency; and the system integration is low: the chemical injection execution mechanism and anti-clogging device are mostly designed separately, with poor coordination and large space occupation, which is not conducive to operation in confined spaces.
