[0033] The upper surface of the U-shaped moving plate 1 is fixed with a side plate 101 on both sides of the sampling pipe 3, a square through groove 102 is formed in each of the two side plates 101, a guide rod 1021 is fixed in each of the two square through grooves 102 symmetrically, a sliding plate 201 is slidingly arranged in each of the two square through grooves 102, the two sliding plates 201 are sleeved on the guide rods 1021 and are in sliding connection, the two sliding plates 201 are welded to the outer wall of the downward moving plate 2, the top end of each of the two side plates 101 is fixed with a hydraulic cylinder 103 through a screw, the telescopic end of each of the two hydraulic cylinders 103 is screw-fixed to the upper surface of the sliding plate 201, the top of the sampling pipe 3 is provided with a driving assembly 5, the driving assembly 5 is used for controlling the sampling pipe 3 to rotate and hammer the vertical rod 303, so that the drill bit 4 makes reciprocating impact to break hard rock geology during sampling, and the outer wall of the sampling pipe 3 is symmetrically provided with a sampling hole 305 at the bottom.

[0034] When the geological exploration work is carried out, 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 its axis through the driving motor 501, the rotating sampling pipe 3 drives the installed drill bit 4 to rotate synchronously, and the driving motor 501 rotates at the same time, and also controls the cam 507 to rotate through the meshing 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 arrangement of the wear-resistant pad effectively reduces the wear of the contact part of the cam 507 and the vertical rod 303, and prolongs the service life of the component;

[0035] When the vertical rod 303 is hit, it moves downward in the sleeve 302 along the annular block 304, 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 plug 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. When the movable plate 403 moves downward, the bottom end thereof is always connected with the top end of the drill bit 4, and the annular plate 4031 slides in the movable cavity 4021 to provide stable guidance for the movement of the movable plate 403. The annular plug plate 401 slides in the insertion groove 306, and the bottom end sealing gasket of the sleeve 302 is tightly attached to the sealing plate 404 to form a double-layer sealing structure, which effectively blocks soil particles and impurities in the drilling process from entering the inside of the sampling tube 3, and avoids the jamming and wear of the transmission components;

[0036] 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 through the cycle;

[0037] Then two hydraulic cylinders 103 are started to push the connected sliding plates 201 to vertically slide downward 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 entire driving assembly 5 and the sampling tube 3 to vertically push downward, 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 to complete the sample collection. 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 as to ensure that the drill bit 4 can continuously penetrate into the geological layer for sampling;

[0038] When the sampling is completed, the extension end of the hydraulic cylinder 103 is retracted to drive the sliding plates 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. At this time, the drill bit 4 can be detached from the sampling tube 3, that is, the upper surface of the sealing plate 404 is separated from the bottom end of the sleeve 302, so that the collected sample can be taken out, and the drill bit 4 can be cleaned, maintained or replaced;

[0039] 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.
