Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically a construction soil sampling device. Background Technology

[0002] In fields such as construction, geological exploration, and environmental monitoring, accurate soil sampling is crucial for assessing soil quality, designing foundation engineering projects, and monitoring environmental pollution. Soil sampling is an indispensable foundational task in soil engineering, geological exploration, environmental protection, and agricultural research. By collecting soil samples from different depths and regions, important data support can be provided for subsequent soil property analysis, pollution assessment, and agricultural soil improvement. The quality of soil sampling directly affects the accuracy and reliability of analytical results; therefore, the design of soil sampling equipment is of paramount importance.

[0003] The prior art discloses some utility model patents in the field of soil sampling and processing technology. Among them, utility model patent with publication number CN219319807U discloses a soil sampling device, including: a base placed at the bottom, a sampling drill barrel and a sample barrel movably arranged coaxially on the base; a support foot is provided under the base, and a nut support, a support plate and a sample barrel baffle are movably arranged sequentially on the base, with a screw threadedly connected to the nut support; the sampling drill barrel includes: a dredging groove opened on the main body, a hollow rotating handle connected to the main body on the main body; flanges and drill teeth are respectively provided at both ends of the main body; a top plate is provided inside the drill barrel; the device reduces the contact area between the sample and the inner wall of the drill barrel by opening a dredging groove on the drill barrel, thereby reducing the friction between the two; the relative movement between the top plate and the drill barrel is achieved by the cooperation of the top plate, the drill barrel and the screw, and the mechanical external force generated by the device forces the sample in the drill barrel to slide out along the inner wall. This device overcomes the resistance between the sample and the inner wall of the drill barrel while preserving the texture and integrity of the sample.

[0004] However, the above method still has the following drawbacks in actual use: most of the drilling barrels in the current sampling devices are one-piece, making it difficult to clean the inside. After long-term use, soil residues and pollutants are easy to accumulate inside the drilling barrel, which can affect the accuracy of sampling and the service life of the device.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a soil sampling device includes a connecting plate 1, a connecting ring 2 fixedly connected to the lower part of the connecting plate 1, a drill barrel 3 connected to the lower part of the connecting ring 2, an arc-shaped groove 7 opened in the connecting ring 2, a connecting structure 6 connected to the upper part of the drill barrel 3, the connecting structure 6 being snapped into the arc-shaped groove 7, a sealing structure 5 being provided in the drill barrel 3, and the connecting structure 6 including a mounting column 601 and an arc-shaped plate 602, a bolt 603 being provided in the mounting column 601, and the mounting column 601 being snapped into the arc-shaped groove 7.

[0023] like Figure 1 and Figure 3As shown, a rotating shaft 4 is slidably connected inside the connecting plate 1. The rotating shaft 4 is slidably connected inside the drill barrel 3. The drill barrel 3 overlaps under the connecting ring 2. The mounting column 601 is slidably connected inside the connecting structure 6. The arc-shaped plate 602 is fixedly connected above the connecting ring 2. The mounting column 601 is fixedly connected above the drill barrel 3. The arc-shaped plate 602 is snapped into the mounting column 601. The arc-shaped plate 602 is connected to the mounting column 601 by bolt 603.

[0024] By setting the arc-shaped groove 7, the drill barrel 3 is inserted into the arc-shaped groove 7 through the mounting post 601, and then the drill barrel 3 is driven to rotate under the connecting ring 2. The mounting post 601 will slide in the arc-shaped groove 7, so that the arc-shaped groove 7 plays a certain guiding role for the rotation of the mounting post 601 and avoids the mounting post 601 from colliding with the connecting ring 2 when rotating.

[0025] like Figure 4 As shown, the sealing structure 5 includes a sleeve plate 501 and a mounting plate 502. A sealing ring 505 is connected inside the mounting plate 502. A bolt 503 is fixedly connected to one side of the mounting plate 502. The sleeve plate 501 is fixedly connected to the outside of the drill barrel 3. The bolt 503 is snapped into the inside of the sleeve plate 501. A nut 504 is connected to the external thread of the bolt 503. The bolt 503 is connected to the sleeve plate 501 through the nut 504. The mounting plate 502 is snapped into the inside of the drill barrel 3. The sealing ring 505 is snapped into the inside of the drill barrel 3.

[0026] By setting a sealing ring 505, when the mounting plate 502 is connected to the drill barrel 3, the sealing ring 505 will directly contact the bottom of the drill barrel 3, and the sealing ring 505 will seal the soil sampled inside the drill barrel 3 to prevent the soil from scattering.

[0027] This utility model provides a soil sampling device for construction, the specific working principle of which is as follows:

[0028] When the sampling device is sampling the soil layer, the drill barrel 3 can be inserted into the arc groove 7 through the mounting column 601, and then the drill barrel 3 is rotated under the connecting ring 2. When the drill barrel 3 rotates to the appropriate position, the arc plate 602 will be locked in the mounting column 601. Then the arc plate 602 is connected to the mounting column 601 through bolt 603. Then the drill barrel 3 is placed in the sampling area, and the sampling area is sampled through the rotating shaft 4. After the soil is sampled, it will be stored in the drill barrel 3. When it is necessary to seal the soil in the drill barrel 3, the mounting plate 502 can be locked into the drill barrel 3, and the sealing ring 505 in the mounting plate 502 will be locked into the bottom of the drill barrel 3. One side of the mounting plate 502 is inserted into the sleeve plate 501 through bolt 503. Bolt 503 is connected to the sleeve plate 501 through nut 504.
