[0002] Soil sampling is an important part of environmental engineering testing. By testing the physical, chemical and biological indicators in the soil, we can understand the degree of soil pollution and soil quality, so as to formulate scientific soil management measures. The existing soil sampling device is generally composed of a support frame, a sampling tube, a connecting shaft and a rotating handle.

[0003] Existing application number: CN202321939054.5, the utility model discloses a soil detection sampling device, including a connecting seat, a motor is provided on the connecting seat, handles are provided on both sides of the connecting seat, the motor output shaft is connected to a sampling rod through a coupling, and the sampling rod passes through the connecting seat, the end of the sampling rod is provided with a cavity for sampling inside, the outside of the connecting seat is provided with a support frame for supporting on the ground, the support frame passes through the middle gap of the handle and is located above the handle, both sides of the connecting seat are provided with connecting rods, and the other end of the connecting rod is connected to the inner side of the support frame and is slidably connected to the support frame, the outside of the sampling rod is provided with a cleaning ring, and the cavity at the end of the sampling rod is provided with a soil discharge block, which can push out the sampled soil. The soil detection sampling device can be supported on the ground during sampling, and does not need to be held by hand all the time. At the same time, the soil remaining on the outer wall of the sampling rod can be scraped and cleaned to avoid cross-infection of soil samples affecting the detection results.

[0004] Based on the above, after the soil sampling is completed, the sampling tube needs to be continuously knocked to loosen the adhesion between the sampling tube and the internal soil, so as to make it easier to remove the soil from the sampling tube. However, such operation is likely to cause the soil in the sampling tube to fall off in powder form, and the integrity of the soil sample is poor. The stratification of the soil cannot be well observed. When the soil moisture is high, the soil will stick to the inner wall of the sampling tube, which is more difficult to clean.

[0064] The connecting member 602 is rotatably connected to the bottom of the transmission screw 6, and its function is to rotate the knob 601 to drive the connecting member 602 to move downward through the threaded transmission mechanism formed by the transmission screw 6 and the ground pin 5.

[0065] The fixing components also include:

[0066] An upper transmission rod 603, wherein the upper transmission rod 603 is provided with two pieces, and the two pieces of the upper transmission rod 603 are discretely hingedly connected under the connecting piece 602;
