[0025] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0026] The specific structure of this embodiment is as follows: Figure 1-3 As shown, a soil sampling device for facilitating sample extraction comprises: a limiting plate 1, a pedal 2 is arranged on one side of the limiting plate 1, a retaining cone 3 is arranged at the bottom of the pedal 2, a first motor 4 is arranged on the top of the limiting plate 1, a first threaded rod 5 is arranged at one end of the first motor 4, a retaining plate 6 is sleeved on the surface of the first threaded rod 5, a second motor 7 is arranged at the bottom of one end of the retaining plate 6, a connecting frame 8 is arranged at one end of the second motor 7, and a sampling component 9 is arranged at the bottom of the connecting frame 8.

[0027] In some examples, a pedal 2 is fixedly installed on one side of the limit plate 1, a retaining cone 3 is fixedly installed on the bottom of the pedal 2, a first motor 4 is fixedly installed on the top of the limit plate 1, a first threaded rod 5 is fixedly installed on one end of the first motor 4, and one end of the first threaded rod 5 extends to the inside of the limit plate 1, a retaining plate 6 is threadedly connected to the surface of the first threaded rod 5, a second motor 7 is fixedly installed on the bottom of one end of the retaining plate 6, and a connecting frame 8 is fixedly installed on one end of the second motor 7. The first motor 4 drives the first threaded rod 5 to rotate, and further drives the retaining plate 6 to move up and down.

[0028] In some examples, the sampling assembly 9 includes a sampling barrel 901, a limiting groove 902, an annular groove 903, a first hand wheel 904, a limiting plate 906, a second threaded rod 907, a push plate 908, a guide groove 909, a guide block 910, a second hand wheel 911 and a cutting plate 912. The sampling barrel 901 is fixedly installed at the bottom of the connecting frame 8. The limiting groove 902 is provided in the top of the sampling barrel 901. The annular groove 903 is provided on the inner wall of the sampling barrel 901. The first hand wheel 904 is located at the top of the sampling barrel 901. One end of the first hand wheel 904 extends into the limiting groove 902 and is fixedly installed with the limiting groove 902. A positioning plate 906 is provided, and a second threaded rod 907 is fixedly installed at the bottom of the limiting plate 906, and one end of the second threaded rod 907 extends into the interior of the sampling tube 901, and a push plate 908 is threadedly connected to the surface of the second threaded rod 907, and guide grooves 909 are provided on both sides of the inner wall of the sampling tube 901, and guide blocks 910 are fixedly installed on both sides of the push plate 908, and one end of the guide block 910 extends into the guide groove 909. By rotating the first hand wheel 904, the limiting plate 906 and the second threaded rod 907 are further driven, and the push plate 908 is further forced to move downward, and the soil column is pushed out of the sampling tube 901.

[0029] In some examples, the second hand wheel 911 is located on both sides of the top of the sampling barrel 901, one end of the second hand wheel 911 passes through the sampling barrel 901 and extends into the annular groove 903, the cutting plate 912 is located inside the annular groove 903, and the top of one end of the cutting plate 912 is fixedly connected to one end of the second hand wheel 911. By rotating the second hand wheel 911, the cutting plate 912 is further driven to rotate toward the axis of the sampling barrel 901, thereby cutting the soil column inside the sampling barrel 901 to avoid being connected with the original soil, and at the same time supporting the bottom of the soil column.

[0030] In a specific application scenario, the retaining cone 3 is embedded in the ground surface, and the pedal 2 is stepped on at the same time, and the first motor 4 is started to drive the first threaded rod 5, forcing the retaining plate 6 to move downward, and the second motor 7 is further started to drive the sampling tube 901 to rotate through the connecting frame 8, so that it is embedded in the soil. When the sampling tube 901 reaches the specified depth, the second hand wheel 911 is turned to further rotate the cutting plate 912 toward the axis of the sampling tube 901 to cut the soil column inside the sampling tube 901 and support the soil column at the same time. The first motor 4 drives the first threaded rod 5 to reverse and the retaining plate 6 rises. When the sampling tube 901 is completely separated from the soil, the first hand wheel 904 is further turned to drive the limiting plate 906 and the second threaded rod 907 to force the push plate 908 to move downward and push the soil column out of the sampling tube 901.

[0031] By adopting the above technical solution: the soil column of the soil sampling device which is convenient for sample extraction is not easy to break, and the sample can be easily taken out.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
