Sampling device special for geological exploration

The utility model relates to the technical field of geological exploration, in particular to a sampling device special for geological exploration. Comprising a mounting plate, supporting rods are arranged on the bottom wall of the mounting plate in an array mode, a collecting mechanism is arranged on the bottom wall of the mounting plate, a movement mechanism used for movement of a lifting lead screw is arranged in the mounting plate, a connecting mechanism is arranged on the end wall of the upper side of the lifting lead screw, and a sampling mechanism is arranged on the bottom wall of the lifting lead screw. By means of the mechanism, automatic sampling can be achieved through movement of the mechanism, samples in a drill bit after sampling can be automatically taken out, the angle of the drill bit can be adjusted, and the samples in the drill bit can be pushed out; through the movement of the mechanism, sampling exploration at different depths can be realized; and the movement of the mechanism can be reali
