These projects primarily include air pollution prevention and control projects, water pollution prevention and control projects, solid waste treatment and utilization projects, and noise control projects. When investigating soil pollution, environmental protection project personnel typically use soil sampling devices to collect soil samples.

[0003] When taking soil samples, because the terrain at the sampling location is relatively complex and the soil is not flat enough, the existing soil sampling device is not balanced enough when placed at the sampling location, and the sampling tube is inserted into the soil at an angle, making it impossible to take samples vertically from top to bottom, resulting in inaccurate sampling data. In addition, the existing sampling tube is not convenient for fixed-layer sampling, and it is difficult to separate multi-layer samples. It is not easy to take samples at the required depth as required, resulting in confusion in the sample data. Utility Model Content

It is not easy to sample samples at the required depth according to requirements, resulting in confusion in sample data.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soil sampling device for environmental protection engineering, comprising a device base, wherein the four corners of the upper side of the device base are penetrated by a first threaded hole, a ground nail is movably provided inside the first threaded hole, a spirit level is symmetrically provided on the upper side of the device base, a second threaded hole is penetrated by the upper center of the device base, a sampling barrel is movably provided inside the second threaded hole, a spiral sampling drill bit is fixedly connected to the lower side of the sampling barrel, a sampling port is provided at the lower end of the spiral sampling drill bit, the upper end of the sampling barrel is threadedly connected to a top cover, the lower side of the top cover is fixedly connected to a push rod, the lower end of the push rod is fixedly connected to a push sealing plate, and the outer side of the sampling barrel is fixedly connected to a rotating disk.

[0008] Preferably, a second thread is provided on the outer side of the sampling cylinder, and the sampling cylinder is threadedly connected to the second threaded hole through the second thread.

[0009] Preferably, the pushing rod is located on the inner side of the sampling cylinder, and the outer periphery of the pushing sealing plate is in contact with the inner wall of the sampling port.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1) The device can adjust the position of the ground nail through the first thread according to the indication of the spirit level, and adjust the inclination of the device base to make the device base level. This design can make the device base level, and the sampling tube can be sampled vertically from top to bottom, avoiding the problem of inaccurate sample data caused by the tilted angle of the sampling tube entering the soil.

[0012] 2) After the sampling tube reaches a certain depth in the soil, the device can unscrew the top cover to release the seal of the push sealing plate, allowing the sampling tube to collect the sampled soil at a fixed depth. Then, the push rod can be pushed by holding the top cover to push the sealing plate to push the sampled soil out for collection. This design can completely remove the sampled soil to prevent the sampled soil from affecting the next sampling sample. In addition, the device can perform fixed-layer sampling, and the sample data is more accurate. BRIEF DESCRIPTION OF THE DRAWINGS
