[0022] When the geological exploration work is performed, the workers move the device to the sampling position through the moving wheels, the workers start the device through the controller 1041, the driving assembly 5 works, the sampling pipe 3 is driven to rotate around the axis thereof through the driving motor 501, the rotating sampling pipe 3 drives the installed drill bit 4 to synchronously rotate, and the driving motor 501 rotates, and the cam 507 is controlled to rotate through the meshed bevel gears, the rim of the cam 507 penetrates through the strip-shaped through groove 2041 in the bottom of the protective shell 204, and periodically hammers the top end of the vertical rod 303, wherein the wear-resistant pad is arranged to effectively reduce the wear of the contact part of the cam 507 and the vertical rod 303, and prolong the service life of the component; The vertical rod 303 moves downward in the sleeve 302 along the annular block 304 after being hammered, and the ear plate 3031 also moves synchronously during the movement of the vertical rod 303, and the reset spring 3032 is extruded. The moving vertical rod 303 transmits the force to the drill bit 4 through the top rod 405, and the drill bit 4 moves downward to drive the vertical plate 406, the movable plate 403 and the annular insert plate 401 to move downward synchronously, and the stretching spring 4051 is stretched. At this time, the vertical plate 406 drives the limiting block 4061 to slide along the limiting groove 4022, and the limiting block 4061 and the limiting groove 4022 can make the threaded tube 402 move synchronously with the drill bit 4 while avoiding relative rotation between the two, so as to ensure that the threaded tube 402 is stably engaged with the internal thread on the inner wall of the bottom end of the sampling tube 3. The bottom end of the movable plate 403 is always connected with the top end of the drill bit 4 when the movable plate 403 moves downward, and the annular plate 4031 slides in the movable cavity 4021 to provide stable guidance for the movement of the movable plate 403.

When the cam 507 rotates to a position away from the vertical rod 303, the vertical rod 303 is reset upward under the elastic action of the reset spring 3032, and at the same time the stretching spring 4051 also pulls the drill bit 4 to reset upward, so as to form a continuous and stable impact breaking action of the drill bit 4. Then the two hydraulic cylinders 103 are started, and the connected sliding plates 201 are pushed to slide vertically along the guide rods 1021 in the square through grooves 102, and the two sliding plates 201 drive the downward moving plate 2 to move downward synchronously, and the downward moving plate 2 drives the whole driving assembly 5 and the sampling tube 3 to vertically push down, so that the drill bit 4 gradually contacts the geological layer to be sampled, continuously rotates and impacts and breaks the geological soil body, and the broken rock-soil sample enters the inside of the sampling tube 3 through the sampling hole 305, and the sample collection is completed. With the increase of the drilling depth, the hydraulic cylinder 103 continuously pushes the downward moving plate 2 to drive the sampling tube 3 to move downward, so that the drill bit 4 can continuously penetrate into the geological layer for sampling. When the sampling is completed, the extension end of the hydraulic cylinder 103 is retracted to drive the sliding plate 201, the downward moving plate 2 and the sampling tube 3 and other components to move upward, so that the drill bit 4 is separated from the geological layer, and then the driving assembly 5 stops working. The worker rotates the drill bit 4 to drive the threaded tube 402 to rotate through the vertical plate 406 and the limiting block 4061, and the internal thread on the inner wall of the bottom end of the sampling tube 3 is gradually separated from the threaded tube 402.

The collected sample can be taken out, and the drill bit 4 can be cleaned, maintained or replaced. Thus, the drill bit 4 forms a continuous and stable impact breaking action, effectively breaking through the drilling resistance caused by hard rock and special geological structure, avoiding the difficulty of advancing caused by pure rotary drilling, and forming a double-layer sealing barrier when the drill bit 4 performs reciprocating impact motion, effectively preventing soil particles and impurities from entering the inside of the sampling pipe 3 during drilling, and avoiding the jamming and wear of the transmission components.
