The top of the moving plate 413 is connected to one side of the second motor 412. The output shaft of the second motor 412 passes through the top of the moving plate 413 and is connected to one end of the moving rod 414. The inner wall of the first cylinder 405 is provided with two sliding grooves 418. The inner wall of the sliding groove 418 is slidably connected to a slider 417. One side of the slider 417 is connected to the outer wall of the moving plate 413. The inner wall of the sampling tube 406 is provided with two moving grooves 420. The inner wall of the moving groove 420 is slidably connected to a sliding block 419. One side of the sliding block 419 is connected to the outer wall of the moving plate 413. The outer wall of the push plate 416 is connected, the outer wall of the first cylinder 405 is connected to a fixing ring 411, the outer wall of the fixing ring 411 is connected to two connecting plates 404, and a threaded groove 403 is opened in one of the connecting plates 404, and a sliding groove 409 is opened in the other connecting plate 404. The output shaft of the first motor 401 passes through the top of the fixed block 1 and is connected to a threaded rod 402. The other end of the threaded rod 402 is rotatably connected to the top of the base 6, and the outer wall of the threaded rod 402 is threadedly connected to the inner wall of the threaded groove 403.

[0031] The specific implementation is as follows: the threaded rod 402 is driven to rotate forward by the output shaft of the first motor 401, and the threaded rod 402 drives one of the connecting plates 404 to move downward by rotating forward in the thread groove 403, so that the first cylinder 405 and the sampling cylinder 406 can be driven downward together through the fixing ring 411, so that the sampling cylinder 406 can be inserted into the soil, thereby sampling the soil. In the process of the sampling cylinder 406 being inserted into the soil, the moving rod 414 is driven to rotate by the output shaft of the second motor 412, and the moving rod 414 rotates to drive the push plate 416 to rotate. The push plate 416 rotates to drive the two sliding blocks 419 to rotate, and can drive the sampling cylinder 406 to rotate by blocking the moving groove 420, so that the sampling cylinder 406 can be more easily inserted into the soil. After the sampling is completed, the threaded rod 402 is driven to rotate in the opposite direction by the output shaft of the first motor 401, so that one of the connecting plates 404 can be driven to rotate in the opposite direction. The connecting plate 404 moves upward and can drive the first cylinder 405 and the sampling cylinder 406 to move upward together through the fixing ring 411, so that the sampling cylinder 406 can be pulled out of the soil. When the first cylinder 405 and the sampling cylinder 406 continue to move upward, the bottom end of the push rod 407 will contact the top of the second motor 412, thereby being able to drive the second motor 412 to move downward by squeezing. The second motor 412 moves downward to drive the movable plate 413 and the movable rod 414 to move downward. The movable rod 414 moves downward to drive the push plate 416 to move downward, so that the push plate 416 can push out the soil sample in the sampling cylinder 406, thereby facilitating the removal of the soil sample, reducing the time required for sampling, and thereby improving the sampling efficiency. When the movable plate 413 moves downward, it can drive the spring 415 to be compressed, so that the spring 415 generates elastic force, so that when the second motor 412 is no longer squeezed by the push rod 407, the push plate 416 can be driven to return to its original position.

[0032] The inner wall of the slide groove 409 is slidably connected with a slide rod 408, and both ends of the slide rod 408 are respectively connected to the bottom of the fixed block 1 and the top of the base 6. Two through grooves 3 are provided in the fixed block 1, and handles 2 are connected on both sides of the fixed block 1, and the tops of the two connecting plates 404 are connected to the same adjusting mechanism 5. The adjusting mechanism 5 includes a placement groove 505 and two cylinders 501. The placement groove 505 is provided at the bottom of the first cylinder 405, and one side of the cylinder 501 is connected to the top of the connecting plate 404. The cylinder 501 push rod passes through the top of the connecting plate 404 and is connected to the fixed plate 502. Travel grooves 503 are provided on both sides of the inner wall of the placement groove 505, and the outer wall of the fixed plate 502 is slidably connected to the inner wall of the travel groove 503, and one side of the two fixed plates 502 is connected to the same second cylinder 504, and the outer wall of the second cylinder 504 is slidably connected to the inner wall of the placement groove 505, and the bottom of the second cylinder 504 is rotatably connected to the top of the sampling tube 406.

[0033] The specific implementation method is as follows: the two cylinder 501 push rods move downward, driving the two fixed plates 502 to move downward, and the two fixed plates 502 move downward, driving the same second cylinder 504 to move downward, so that the second cylinder 504 slides out of the placement groove 505, thereby driving the sampling cylinder 406 to move downward, so that the overall length of the sampler is extended, and then the overall length of the sampler can be adjusted, so that the sampler can adapt to the soil sampling needs of different depths, thereby improving the applicability of the sampler. When the sampling cylinder 406 moves downward, the push plate 416 will follow the sampling cylinder 406 to move downward, so that it can be adaptively adjusted according to the movement of the sampling cylinder 406. After the extended sampler takes the soil sample, it only needs to be restored to the length of the sampler itself, and the operation of pushing out the sample can be repeated, so that the sample can be taken out of the sampling cylinder 406.

[0034] Working principle: When in use, the first motor 401 is started, and the output shaft of the first motor 401 rotates in the reverse direction to drive the threaded rod 402 to rotate in the reverse direction. The threaded rod 402 drives one of the connecting plates 404 to move upward by rotating in the reverse direction in the threaded groove 403, and can drive the first cylinder 405 and the sampling cylinder 406 to move upward together through the fixing ring 411, so that the sampling cylinder 406 that has completed sampling can be pulled out of the soil. When the first cylinder 405 and the sampling cylinder 406 continue to move upward, the bottom end of the push rod 407 will contact the top of the second motor 412, so that The pressure drives the second motor 412 and the movable plate 413 to move downward, and can drive the push plate 416 to move downward through the movable rod 414, so that the push plate 416 can push the soil sample in the sampling tube 406 out, thereby facilitating the removal of the soil sample. When it is necessary to sample deeper soil, the two cylinders 501 are started, and the push rods of the two cylinders 501 move downward to drive the two fixed plates 502 to move downward, and can drive the sampling tube 406 to move downward through the second cylinder 504, so that the overall length of the sampler is extended, so that deeper soil can be sampled.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
