Soil sample collecting device for soil heavy metal pollution treatment

The utility model relates to the technical field of soil treatment, in particular to a soil sample collecting device for soil heavy metal pollution treatment, which is characterized in that four locking universal wheels which are symmetrically arranged are respectively and fixedly connected to four corners of the bottom of a supporting plate, and a concave frame which is vertically arranged is fixedly connected to the upper side of the supporting plate; a lifting adjusting mechanism is fixedly connected between the concave frame and the supporting plate, two positioning supporting mechanisms are fixedly connected between the concave frame and the supporting plate, and the two positioning supporting mechanisms are symmetrically located on the two sides of the lifting adjusting mechanism respectively. According to the soil sampling device, the soil sampling mechanism and the lifting adjusting mechanism are arranged for sampling a soil sample, the semi-automation degree is higher, the operation is convenient, ma
