[0031] The technical scheme of the utility model is applied, and the soil sampling device includes support seat 100, sampling cylinder 300 and extension ring 400, when soil sampling is carried out, support seat 100 can be placed in the sampling area, sampling cylinder 300 and extension ring 400 are driven by driving element 200 to sample soil, when sampling shallow soil layer, sampling cylinder 300 can be used for sampling, when sampling cylinder 300 is used for sampling, the first cutting part of sampling cylinder 300 penetrates the soil layer, when sampling deep soil layer, sampling cylinder 300 and extension ring 400 can be used for sampling in cooperation, and the second cutting part of extension ring 400 penetrates the soil layer.The soil sampling device provided in the application can meet different sampling depths by adjusting the number of extension ring 400, the applicability of the soil sampling device can be improved by removing or installing extension ring 400, and each extension ring 400 is provided with a second cutting part, compared with the scheme of using extension pipe or other extension structure, the soil sampling device provided in the application can be adjusted only by disassembling and assembling once, so that the convenience of operation is improved.

[0032] As Figure 2 And Figure 3 As shown, the inner wall of cutting end 401 is provided with first thread structure, connecting end 402 has connecting boss, and the outer wall of connecting boss is provided with second thread structure, and first thread structure and second thread structure are threadedly matched.Through the above-mentioned setting, extension ring 400 can be conveniently connected or disassembled, and the disassembly efficiency of the soil sampling device is improved.Moreover, by providing first thread structure on the inner wall of cutting end 401, the second cutting structure can also not be damaged, so that the normal cutting function of the second cutting structure is ensured.

[0033] Similarly, the driving end 301 of the sampling cylinder 300 is provided with a connecting plate 500 for driving connection with the driving member 200, an outer wall of the connecting plate 500 is provided with a third threaded portion, and an inner wall of the driving end 301 is provided with a fourth threaded portion, and the third threaded portion is in threaded cooperation with the fourth threaded portion. Through the above setting, the sampling cylinder 300 can be conveniently disassembled and assembled with the driving member 200, and the installation efficiency is improved.

[0034] In other embodiments of the present application, the sampling cylinder 300 and the extension ring 400, and the extension ring 400 and the extension ring 400 can also be connected by a clamping piece or a fastener.

[0035] In another specific embodiment of the present application, a retaining ring is arranged on the connecting end 402, the retaining ring is located at the outer periphery of the connecting boss, and the connecting boss and the retaining ring have a spacing therebetween, the spacing forms an accommodating groove, and the accommodating groove is used to accommodate the first cutting portion. Through the above setting, when the sampling cylinder 300 and the extension ring 400 are connected, the first cutting portion can be deeply inserted into the accommodating groove to protect the first cutting portion and prevent the solid matter in the soil from bumping the first cutting portion to cause damage or destruction of the first cutting portion. Similarly, when multiple extension rings 400 are connected, the retaining ring can also protect the second cutting portion from damage or destruction, thereby improving the service life of the soil sampling device.

[0036] Further, the connecting boss does not protrude from the retaining ring in the axial direction of the extension ring, that is, the height of the retaining ring is greater than or equal to the height of the connecting boss. During use of the soil sampling device, soil is easy to enter the accommodating groove, causing the sampling cylinder 300 and the extension ring 400, and the extension ring 400 and the extension ring 400 to be unable to be installed in place according to the designed length when connected. By setting the height of the retaining ring to be greater than or equal to the height of the connecting boss, when the first cutting portion or the second cutting portion does not completely enter the installation groove, the retaining ring can still play a protective role on the first cutting portion or the second cutting portion, thereby ensuring the protective effect of the retaining ring.

[0037] Specifically, the connecting plate 500 is provided with a communication hole 510 for communicating the outside with the collection cavity.

[0038] Further, the communication hole 510 is provided with a blocking piece for blocking or opening the communication hole 510. By providing the blocking piece, when the driving sampling cylinder 300 and the extension ring 400 move towards the soil layer to puncture the soil for collection, the communication hole 510 can be opened to communicate the outside with the collection cavity, balance the internal and external air pressure; when the driving sampling cylinder 300 and the extension ring 400 move away from the soil layer and the sampling soil is taken out, the blocking piece can be used to block the communication hole 510, so that negative pressure is generated in the collection cavity, the risk of falling of the sampling soil is reduced, and the use effect of the soil sampling device is improved.

[0039] Specifically, the blocking piece can be selected from a rubber plug and the like.

[0041] Further, the support seat 100 further includes a bottom plate 130, the bottom plate 130 is provided with a collection window, the collection window is arranged corresponding to the sampling cylinder 300, the sampling cylinder 300 can pass through the collection window, the vertical plate 110 is detachably arranged on the bottom plate 130, and a height adjusting structure is arranged between the vertical plate 110 and the bottom plate 130. Through the above arrangement, the height adjusting structure can facilitate the overall soil sampling device to adapt to the demand of different sampling depths. When the sampling depth is shallow, the top plate 120 can be made close to the ground through the height adjusting structure; when the sampling depth is deep, the top plate 120 can be made away from the ground through the height adjusting structure, so that the sampling cylinder 300 and the extension ring 400 can have enough displacement space.
