Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a deep soil sampling device in an alpine meadow area. Background Art

[0002] Alpine meadow soil is a typical soil type. With the large-scale construction of new energy sources such as wind and solar energy in the region, meadow destruction and soil erosion have been aggravated. In order to restore vegetation and maintain soil and water, it is necessary to collect soil samples to ensure the representativeness and effectiveness of the samples. Soil sampling devices are important tools in the process of collecting soil samples.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN216012808U, which discloses a deep soil sampling device capable of sampling deep soil. The deep soil sampling device comprises a bottom plate, an outer barrel, a sampling slot and a sampling barrel. The outer barrel is connected to the bottom plate and can move up and down along the vertical direction of the bottom plate. A circular hole is provided on the bottom plate, and the outer barrel can pass through the circular hole. The sampling barrel is rotatably connected to the outer barrel. A plurality of sampling slots are provided on the sampling barrel and the outer barrel. The outer barrel can rotate around its own center of circle as an axis. The outer barrel can rotate clockwise to drive the sampling barrel to rotate.

[0004] Since the device needs to be inserted into the soil when sampling deep soil, and the device is taken out after sampling is completed, the sampling tube cannot be easily pulled out after soil sampling is completed due to the friction between the soil and the outer wall of the sampling tube. In addition, the soil sample of the existing sampling equipment will be blocked inside the sampling tube due to friction after sampling is completed, and the soil sample cannot be easily taken out from the sampling tube.

[0033] Specifically, the support frame 1 can limit the direction of the sampling tube 11, and the sampling tube 11 can penetrate the soil. The limit tooth 12 can facilitate limiting the relative position between the sampling tube 11 and the limit ring 16. The transmission rod 13 can drive the connecting rod 14 to rotate, and the connecting rod 14 can change the position of the limit ring 16. The connecting block 15 can facilitate the rotational connection between the connecting rod 14 and the limit ring 16. The limit ring 16 can drive the sampling tube 11 to move upward.

The connecting column 111 can limit the position of the sampling groove 112. The sampling groove 112 can discharge the soil inside the sampling tube 11.

[0034] When in use, firstly, the latch 17 needs to be moved outward through the protrusions on the left and right sides of the latch 17, and then the limiting ring 16 is located at the top of the sampling tube 11, and then the sampling tube 11 is knocked into the soil through the protrusion structure at the top of the sampling tube 11. A certain gap is reserved between the limiting block 110 and the top of the sampling tube 11, and the inner wall of the limiting block 110 is provided with a groove structure matching the sampling groove 112. The connecting column 111 is movably connected with the limiting block 110 through the sampling groove 112, and the outer edge size of the sampling groove 112 is consistent with the inner diameter size of the sampling tube 11. Matching, after the sampling tube 11 is inserted into the soil, the connecting column 111 is inserted into the sampling tube 11 by rotating, and the soil inside the sampling tube 11 will be discharged from the sampling tube 11 from the gap between the top of the sampling tube 11 and the limiting block 110 under the guidance of the sampling groove 112.

The rod 13, the connecting rod 14 and the connecting block 15 are transmitted to the limiting ring 16, so that the limiting ring 16 drives the sampling tube 11 to move upward. This method increases the force arm of the force that moves the sampling tube 11 upward, so as to facilitate the sampling tube 11 to be taken out from the soil. After the sampling tube 11 connected to the connecting column 111 is taken out from the soil, the connecting column 111 is removed by rotating, and the soil inside the sampling groove 112 will fall off from the sampling groove 112 under the restriction of the limiting block 110. This method can prevent the soil sample from blocking the sampling tube 11, so as to facilitate the transfer of the soil sample.
