[0024] like Figures 1 to 3 As shown, a surface soil sampling device comprises a sampling tube 1, a cutting blade 2 is fixedly connected to the bottom surface of the sampling tube 1, a threaded sleeve 3 is fixedly connected to one end of the sampling tube 1, a slider 10 is slidably connected in the sampling tube 1, a first connecting column 4 is threadedly connected to the threaded sleeve 3, a collision block 14 is slidably connected to the first connecting column 4, the moving mechanism comprises two sockets 11 on the sampling tube 1, a plug column 12 is movably inserted in the socket 11, the length of the plug column 12 is the same as the depth of the sampling tube 1, a sleeve 13 is slidably connected to the first connecting column 4, one end of the plug column 12 is connected to the slider 10, and the other end of the plug column 12 is connected to the The sleeve 13 is connected, the plug post 12 is rotatably connected to the slider 10, the plug post 12 is threadedly connected to the sleeve 13, and the soil is cut by the cutting blade 2 at one end of the sampling tube 1, so that it is easier to penetrate into the soil. The threaded sleeve 3 at one end of the sampling tube 1 is threadedly connected to the first connecting column 4, so that it is convenient to disassemble. The slider 10 is slidably connected to the sampling tube 1, so that the soil in the sampling tube 1 is conveniently taken out. The slider 10 is moved by toggling the sleeve 13 to take out the soil. The plug post 12 connected to the slider 10 can be rotated to separate the plug post 12 from the sleeve 13, so that the sampling tube 1 and the slider 10 are convenient to clean.

[0025] like Figures 2 to 4 As shown, one end of the first connecting column 4 is threadedly connected to the second connecting column 5, and the second connecting column 5 is fixedly connected to the supporting column 6. The second connecting column 5 is movably plugged with a pedal 7. The bottom surface of the pedal 7 is fixedly connected with limiting columns 17 arranged correspondingly on both sides. The supporting column 6 is provided with limiting holes that cooperate with the limiting columns 17. The pedal 7 is provided with anti-slip patterns 16. The second connecting column 5 is threadedly connected to the third connecting column 8. The third connecting column 8 is threadedly connected to the push rod 9. The push rod 9 is fixedly connected with anti-slip sleeves 15 arranged correspondingly on both sides. The first connecting column 4, the second connecting column 5, the third connecting column 8, and the push rod 9 are threadedly connected, so as to facilitate disassembly and make the storage space smaller. The pedal 7 movably plugged on the second connecting column 5 is convenient to take out and store. The supporting column 6 on the second connecting column 5 provides supporting force for the pedal 7. The limiting column 17 cooperates with the limiting hole to prevent the pedal 7 from sliding left and right when stepping on.

[0026] In specific use, when it is necessary to sample the soil, the slider 10 is placed in the sampling tube 1, and then the two plug posts 12 on the slider 10 are aligned with the two plug holes 11 on the sampling tube 1, and then the first connecting column 4 is threadedly connected to the sampling tube 1, and then the sleeve 13 is put on the first connecting column 4, and then the two plug posts 12 are threadedly connected to the sleeve 13, and then the collision block 14 is put on the first connecting column 4, and then the second connecting column 5 is threadedly connected to the first connecting column 4, and then the pedal 7 is put on the second connecting column 5, so that the limiting column 17 on the bottom surface of the pedal 7 corresponds to the limiting hole on the support column 6, and the pedal 7 falls on the support column 6 under the action of gravity, and then the third connecting column 8 is threadedly connected to the second connecting column 5, and then the push rod 9 is threadedly connected to the third connecting column 8. At this time, the splicing is completed, and then the push rod 9 is pressed. The foot steps on the pedal 7 and applies downward force. The cutting blade 2 cuts the land and moves downward. The soil enters the sampling tube 1. The soil will push the slider 10 to move upward. When it reaches the appropriate position, lift the push rod 9 upward. At this time, the sampling tube 1 is taken out, and then the collision block 14 is slid back and forth to hit the sleeve 13, thereby pushing the plug post 12 to move, driving the slider 10 to move, causing the soil to overflow, and then collect the soil, and then rotate the push rod 9 to remove it, and then remove the third connecting column 8, remove the pedal 7 from the second connecting column 5, and then rotate the second connecting column 5 to take it out, and then take out the collision block 14, rotate the first connecting column 4 and take it out, and complete the disassembly. When cleaning is needed, rotate the plug post 12 and take out the sleeve 13. At this time, the slider 10 will be separated from the sampling tube 1, so that the inside of the sampling tube 1 and the slider 10 can be cleaned.
