The inner side of the gantry assembly 1 is slidably mounted with a sliding frame 3 in the vertical direction. The sliding frame 3 is horizontally placed on the inner side of the gantry assembly 1. The sliding frame 3 can slide in the vertical direction on the inner side of the gantry assembly 1. The main lifting hydraulic cylinder 4 is fixedly mounted on the gantry assembly 1, and the bottom telescopic end of the main lifting hydraulic cylinder 4 is fixedly mounted on the sliding frame 3. The sliding frame 3 and the gantry assembly 1 are relatively fixed by the bottom telescopic end of the main lifting hydraulic cylinder 4, and the specific sliding of the sliding frame 3 can be controlled under the extension / contraction action of the main lifting hydraulic cylinder 4. The support walking assembly 2 is fixedly mounted Installed at the bottom of the gantry assembly 1, the support walking assembly 2 is used to support the gantry assembly 1 to ensure that the gantry assembly 1 can be stably placed on the ground. When the mineral geological exploration device needs to move, the support walking assembly 2 facilitates the overall movement of the mineral geological exploration device. The guide clamping assembly 5 is slidably installed on the inner side of the gantry assembly 1, and the guide clamping assembly 5 is located below the sliding frame 3. The guide clamping assembly 5 guides the outer drill pipe 8, and the guide clamping assembly 5 can be adjusted to a state of clamping and fixing the outer drill pipe 8 to drive the drill rod The assembly is fixedly installed with the sliding frame 3, and the driving drill rod assembly and the sliding frame 3 slide up and down synchronously. The side thread of the driving drill rod assembly is installed with an outer drill pipe 8, and the outer drill pipe 8 is provided with a second nut 805 for fixing the outer drill pipe 8 and the driving drill rod assembly. The second nut 805 is rotated downward to squeeze the threaded connection between the outer drill pipe 8 and the driving drill rod assembly, so that the fixed outer drill pipe 8 and the driving drill rod assembly can be fixed together. At this time, the driving drill rod assembly can drive the outer drill pipe 8 to rotate. When the second nut 805 is rotated to the uppermost position, the outer drill pipe 8 is fixed. The tube 8 is threadedly connected to the driving drill rod assembly, and the outer drill pipe 8 is clamped and fixed by relying on the guide clamping assembly 5, and the transmission rod 7 of the driving drill rod assembly is rotated. Under the threaded matching structure, the guide clamping assembly 5 and the outer drill pipe 8 are driven to move upward synchronously, and a rotating frame 10 is rotatably installed on the side of the driving drill rod assembly and below the connection between the outer drill pipe 8 and the driving drill rod assembly. A collecting assembly 11 is fixedly installed below the rotating frame 10.

The operator drives the mineral geological exploration device to move to the exploration hole position so that the bottom of the outer drill pipe 8 corresponds to the exploration hole. The bottom telescopic end of the main lifting hydraulic cylinder 4 pushes the sliding frame 3 downward, and the sliding frame 3 drives the driving drill rod assembly, the outer drill pipe 8, the collecting assembly 11 and the spiral blade 12 to move downward, and drives the drill rod assembly to move synchronously, driving the outer drill pipe 8 and the spiral blade 12 to rotate. During this process, the bottom of the outer drill pipe 8 covers an area, and the rotating outer drill pipe 8 continues to open a circular area at the bottom of the exploration hole, and crushed soil / rock is generated in the circular area at the bottom of the outer drill pipe 8. The driving drill rod assembly drives the rotating spiral blade 12 to further crush the crushed soil / rock in the circular area at the bottom of the outer drill pipe 8 and spirally transport it upward, that is, the crushed soil / rock is transported upward at the center of the collecting assembly 11, and the crushed soil / rock passes over the collecting assembly 11. After reaching the top, the crushed soil / rock falls into the collecting assembly 11 for collection. After the collecting assembly 11 has collected an appropriate amount of crushed soil / rock, the driving drill rod assembly is stopped, and the bottom telescopic end of the main lifting hydraulic cylinder 4 pulls the sliding frame 3 upward, and the sliding frame 3 drives the driving drill rod assembly, the outer drill pipe 8, the collecting assembly 11 and the spiral blade 12 to move upward. The outer drill pipe 8 is located on the inner side of the guide clamping assembly 5, and the main lifting hydraulic cylinder 4 stops moving.
