The mounting frame 52 is penetrated and connected with a baffle 53, and the baffle 53 is rotatably connected to the mounting frame 52.

[0044] When the sample storage tube 2 is full of soil samples, the sliding member 51 is pushed upward to be inserted into the baffle 53, and the baffle 53 is rotated ninety degrees, the locking member 5 is unlocked, the elastic rope 43 is retracted, and the connecting frame 41 is pulled downward until the magnetic block 33 with the same pole and the magnetic plate 42 are in the same horizontal plane, so that the separation spring 34 is compressed under the action of the repulsive force, and the two sets of separation plates 31 are inserted into the sample storage tube 2 to separate the soil samples.

Multiple groups of connecting blocks 22 are provided, which are symmetrically distributed between the sample storage cylinder 2 and the outer cylinder 1. A sliding groove 23 is provided on the inner wall of the sample storage cylinder 2.

[0047] Reference Figures 1 to 10 A fixing frame 6 connected to the soil sampling machine is fixedly provided on the outer cylinder 1 to provide pressure for the outer cylinder 1 so that it is inserted into the soil. A connecting stud 61 connected to the soil sampling machine is fixedly connected to the top of the fixing frame 6. A lifting groove 62 is provided on the side end of the fixing frame 6. Two groups of lifting grooves 62 are provided. A positioning magnetic block 63 magnetically connected to the lifting member 44 is embedded in the lifting groove 62. There are multiple groups of positioning magnetic blocks 63. The spacing between each two groups of positioning magnetic blocks 63 is the same as the spacing between two groups of magnetic blocks 33 with the same poles. A fixing groove 1 64 and a fixing groove 2 65 are provided on the inner wall of the lifting groove 62, and the fixing groove 1 64 and the fixing groove 2 65 are symmetrically distributed on the inner wall of the lifting groove 62.

[0050] The above scheme is adopted: the stratification device 3 is controlled by the cooperation of the connecting frame 41, the magnetic plate 42 and the elastic rope 43. When soil samples need to be collected, the movement of the elastic rope 43 will cause the magnetic plate 42 and the magnetic block 33 of the same pole to generate repulsive force, thereby compressing the separation and closing spring 34, closing the separation plate 31, and realizing the separation of soil samples. This automatic closing function ensures the ease of operation and accuracy during the sampling process.

[0054] The above scheme is adopted: through magnetic connection with the positioning magnet 63 in the sample storage tube 2, the position of the connecting frame 41 can be accurately located. This magnetic connection ensures accurate positioning during operation, so that the stratification device 3 can be closed or opened in a predetermined manner, thereby ensuring the correct separation and collection of soil samples. The lifting member 44 can move up and down in the lifting groove 62 through the handle 443 and the movable groove 442, and the handle 443 can be rotated, so that the operator can control and adjust the state of the stratification device 3 through simple movement of the handle 443, thereby realizing the separation or release of soil samples, which greatly simplifies the operation process.

When soil samples need to be collected, the movement of the elastic rope 43 will cause the magnetic plate 42 to generate repulsion with the magnetic block 33 of the same pole by operating the control device 4, thereby compressing the separation spring 34, closing the separation plate 31, and realizing the separation of the soil samples. This automatic closing function ensures the simplicity and accuracy of operation during the sampling process; through the magnetic connection with the positioning magnetic block 63 in the sample storage tube 2, the position of the connecting frame 41 can be accurately located.
