[0028] The first screw 3, telescopic dustproof sleeve 301, first sprocket 304, second sprocket 303, chain 305, and square rotating rod 302 are configured to work together. The second sprocket 303 is driven to rotate by the drive motor 306. The second sprocket 303 drives the square rotating rod 302 to rotate. At the same time, the second sprocket 303 drives the two first sprockets 304 to rotate through the chain 305. The two first sprockets 304 drive the two first screws 3 to rotate. The rotation of the two first screws 3 causes the lifting plate 202 to move downward or upward, and compresses or stretches the multiple telescopic dustproof sleeves 301. The telescopic dustproof sleeves 301 can always cover the first screws 3 to prevent dust, ensuring their long-term stable use. The up-and-down movement of the lifting plate 202 drives the sampling drill barrel 4 to move up and down.

[0029] Furthermore, the lever-driven rotary self-propelled core ejection assembly includes a compression plate 401 movably fitted inside the sampling drill cylinder 4. A square rotating tube 403, slidably fitted outside the square rotating rod 302, is fixedly connected to the top of the compression plate 401. The top end of the square rotating tube 403 slides out to the top of the sampling drill cylinder 4. The top of the sampling drill cylinder 4 has a square sliding hole that slides onto the outside of the square rotating tube 403, allowing the tube to pass through and providing vertical sliding guidance. An outer edge is integrally formed on the top outer side of the square rotating tube 403. Both sides of the top are movably fitted with ball bearings 404, which are in contact with the bottom of the U-shaped top plate 2. Two tension springs 402 are fixedly connected between the top of the extrusion plate 401 and the inner wall of the top of the sampling drill cylinder 4. The extrusion plate 401, square rotating tube 403, ball bearings 404 and tension springs 402 work together, taking advantage of the characteristic of the square parts having corners that fit together. When the square rotating rod 302 rotates, the inner corners of the square rotating tube 403 break and drive it to rotate as a whole. The square rotating tube 403 drives the sampling drill cylinder 4 to rotate as a whole, thus achieving descent. The sampling drill cylinder 4 rotates as a unit, propelling it downwards into the ground through its downward movement and rotation. As it drills, soil samples are squeezed into the sampling drill cylinder, enabling core sampling. During downward movement, the sampling drill cylinder 4 also drives the square rotating tube 403 to slide downwards on the square rotating rod 302 via the tension spring 402 and the compression plate 401. After core sampling, the subsequent driving lifting plate 202 raises the sampling drill cylinder 4, which then moves upwards via the square rotating tube 403, causing the ball bearings 404 to contact the bottom of the U-shaped top plate 2. At this time, the personnel can push the device back slightly to offset the drilling sampling position, and then continue to drive the lifting plate 202 and the sampling drill cylinder 4 to move upward. At this time, the square rotating tube 403 is blocked and restricted from moving upward, so that the extrusion plate 401 cannot continue to move upward. The sampling drill cylinder 4, which continues to move upward, slides upward on the extrusion plate 401 and stretches the tension spring 402. As the sampling drill cylinder 4 moves upward, it causes the core sample on the inside to be squeezed against the bottom of the extrusion plate 401. Under the extrusion force, the core sample is squeezed out from the inside of the sampling drill cylinder 4.

[0030] Further, two threaded through holes are formed on the top of the U-shaped bottom plate 1, and a T-shaped screw rod 102 is threadedly sleeved in the threaded through hole, and the bottom end of the T-shaped screw rod 102 is fixedly connected with a sharp block below the U-shaped bottom plate 1, and the T-shaped screw rod 102 is arranged to be inserted into the ground by rotating the sharp block to increase the stability during parking.

[0031] The use method of the embodiment is: when the advancing type coring device for geological exploration is used, the device is moved to the position where drilling sampling is needed, the driving motor 306 is started in the forward direction to drive the second sprocket 303 to rotate, the second sprocket 303 drives the square rotating rod 302 to rotate, at the same time, the second sprocket 303 drives the two first sprockets 304 to rotate through the chain 305, the two first sprockets 304 drive the two first screws 3 to rotate, the two first screws 3 drive the lifting plate 202 to slide downward on the two vertical guide plates 201 and compress or stretch the plurality of telescopic dustproof rubber sleeves 301, the telescopic dustproof rubber sleeves 301 can always shield the first screw 3 to ensure long-term and stable use, the lifting plate 202 drives the sampling drill cylinder 4 to move downward, when the square rotating rod 302 rotates, the square rotating tube 403 is integrally rotated through the inner side angle of the square rotating tube 403, the square rotating tube 403 drives the sampling drill cylinder 4 to integrally rotate, the effect of driving the sampling drill cylinder 4 to integrally rotate when descending is realized, the sampling drill cylinder 4 is pushed downward and rotated to drill into the ground, with the drilling, the soil sample is extruded into the sampling drill cylinder to realize the coring work, when the sampling drill cylinder 4 moves downward, the square rotating tube 403 is driven to slide downward on the square rotating rod 302 through the tension spring 402 and the extrusion plate 401 in turn;

[0032] After the core is drilled, the driving motor 306 is started in reverse, which is completely opposite to the movement direction of the driving motor 306 started in the above-mentioned forward direction, at this time, the lifting plate 202 and the sampling drill cylinder 4 are changed to move back upward, move out from the ground, when the sampling drill cylinder 4 is moved upward to contact the bottom of the back-shaped top plate 2 by the square tube 403 driving the ball 404, personnel can push the device backward a little to offset the drilling sampling position, and then continue to drive the lifting plate 202 and the sampling drill cylinder 4 to move upward, at this time, the square tube 403 is blocked and limited from moving upward, so that the pressing plate 401 cannot continue to move upward, at this time, the sampling drill cylinder 4 continues to move upward and slides upward on the pressing plate 401 and stretches the tension spring 402, at this time, as the sampling drill cylinder 4 moves upward, the core sample on the inside is pressed with the bottom of the pressing plate 401, under the pressing force, the effect of extruding the core sample from the inside of the sampling drill cylinder 4 is realized, personnel can temporarily place the extruded core sample in the sample placing cylinder for subsequent detection, through a single driving motor 306, the effects of driving the sampling drill cylinder 4 to descend and rotate to drill and sample and automatically extruding the core sample when moving upward after sampling are realized, single driving is realized, and the sample is extruded after sampling, without using multiple power driving devices for personnel to operate step by step, the operation is simple, and compared with the application mode of multiple power devices, the energy-saving application effect is better, the use simplicity and energy-saving nature are improved;

[0033] When the lifting plate 202 is lowered by starting the driving motor 306 in the forward direction again, the lifting plate 202 drives the sampling drill cylinder 4 to move downward and gradually releases the stretching force of the tension spring 402, until the bottom end of the sampling drill cylinder 4 moves downward into the U-shaped bottom plate 1, the sampling work can be performed again.
