[0045] Soil environmental monitoring is an important part of ecological environmental monitoring and an important measure to understand the status of soil environmental quality. It requires soil sampling and processing. Soil environmental monitoring includes the current status of soil environmental quality, the investigation of regional soil environmental background values, the investigation of soil pollution accidents and the dynamic observation of polluted soil.

[0046] In the related art, when collecting soil samples from soft soil, due to the low viscosity between the soil and between the soil and the inner wall of the sampling rod, the soil in the sampling rod will fall out of the sampling port during the process of taking the sampling tube out of the soil, and the integrity of the collected soil sample will be destroyed, which will have a certain impact on the accuracy of the obtained sample data and reduce the accuracy of the sample data.

[0047] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a soil sampler. When it is needed, it is only necessary to push the baffle 24 to close through the driving component 22 to seal the bottom opening of the sampling tube 21, and compact the loose soil in the sampling tube 21 through the compacting component 26 to prevent the soil in the sampling tube 21 from falling out of the soil taking port during the process of taking the sampler out of the soil, thereby ensuring the integrity of the soil sample and improving the accuracy of the sample data. After the sampler is taken out of the soil, the sampling tube 21 is pulled out of the threaded sleeve 11, and the soil sample is pushed out of the sampling tube 21 through the compacting component 26.

[0048] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0049] Combination Figure 1-Figure 4 The embodiment of the present application provides a soil sampler, including a sampler body 1, the sampler body 1 includes: a fixing component 12 is arranged on the outside of a threaded sleeve 11; a soil sampling port 13 is arranged at the bottom of the threaded sleeve 11; a sampling component 2 is arranged inside the threaded sleeve 11, and the sampling component 2 includes: a sampling tube 21 is arranged inside the threaded sleeve 11 and passes through the top of the threaded sleeve 11; a fixing groove 23 is arranged at the inner bottom of the threaded sleeve 11, and the sampling tube 21 is snap-connected; a baffle 24 passes through the outer wall of the fixing groove 23; a driving component 22 is arranged on the threaded sleeve 11; and a compacting component 26 passes through the sampling tube 21.

[0050] When in use, the threaded sleeve 11 is first fixed to the ground by the fixing component 12, and the threaded sleeve 11 is rotated by the handle to move the threaded sleeve 11 downward to take soil. When the threaded sleeve 11 moves downward to the predetermined position, the baffle 24 is pushed to close by the driving component 22 to seal the bottom opening of the sampling tube 21, and the loose soil in the sampling tube 21 is compacted by the compacting component 26 to prevent the soil in the sampling tube 21 from falling out of the soil taking port during the process of taking the sampler out of the soil, thereby ensuring the integrity of the soil sample and improving the accuracy of the sample data. After the sampler is taken out of the soil, the sampling tube 21 is pulled out of the threaded sleeve 11, and the soil sample is pushed out of the sampling tube 21 by the compacting component 26.

[0051] In some embodiments, the driving assembly 22 includes: a first threaded rod 221 that passes through the outer wall of the threaded sleeve 11; a bevel gear 222 is arranged at the bottom of the first threaded rod 221; a second threaded rod 223 is arranged on one side of the bevel gear 222; a moving block 224 is sleeved on the outer side of the second threaded rod 223, and the first threaded rod 221 is rotated. The rotating first threaded rod 221 drives the second threaded rod 223 to rotate through the bevel gear 222, and the rotating second threaded rod 223 drives the baffle 24 to move left and right on the second threaded rod 223 through the moving block 224.

[0052] In some embodiments, the compaction assembly 26 includes: a push rod 261 that passes through the top of the sampling tube 21; a pressure plate 262 that is arranged at the bottom of the push rod 261 and is located inside the sampling tube 21. By pushing the push rod 261 downward, the pressure plate 262 at the bottom of the push rod 261 compacts the loose soil in the sampling tube 21, thereby increasing the viscosity between the soil and the soil, and between the soil and the inner wall of the sampling rod.

[0053] In some embodiments, a connecting plate 25 is disposed on the outer side of the top of the sampling tube 21 and fixed by bolts, thereby increasing the fixity of the sampling tube 21 and facilitating disassembly and assembly.

[0054] In some embodiments, an exhaust hole 27 is provided on the outer wall of the sampling tube 21, and the outer wall of the sampling tube 21 is observed to prevent the air in the sampling tube 21 from being unable to be discharged, resulting in a high air pressure in the sampling tube 21, making it impossible for the pressure plate 262 to move downward, thereby making it impossible to compact the loose soil in the sampling tube 21.

[0055] In some embodiments, the fixing assembly 12 includes: a threaded sleeve 122 is sleeved on the outside of the threaded sleeve 11; a support frame 121 is sleeved on the outside of the threaded sleeve 122, the support frame 121 is placed at a predetermined soil excavation position, and is fixed by fixing screws. After fixing, the threaded sleeve 122 is used to rotate the threaded sleeve 11, so that the threaded sleeve 11 continues to move downward during the continuous rotation process.

[0056] In some embodiments, a limiting ring 123 that matches the threaded sleeve 122 is disposed on the outer side of the threaded sleeve 11 to prevent the threaded sleeve 11 from being separated from the threaded sleeve 122 when the threaded sleeve 11 moves upward or downward.

[0057] In some embodiments, a groove 131 is provided at the top of the borrow opening 13 , and the borrow opening 13 is threadedly connected to the threaded sleeve 11 through bolts, so as to facilitate the disassembly and assembly of the borrow opening 13 .

[0058] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0059] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
