Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically to a rapid soil testing device that prevents clogging. Background Technology

[0002] Soil environmental testing involves drilling and sampling to examine the internal environment of the soil in order to analyze its quality and trends. Currently, a sampling tube is typically drilled into the soil, trapping soil within it to assess the soil conditions at a specific depth. However, after sampling, soil can clog the tube, making it difficult to remove and potentially damaging the soil structure, thus affecting subsequent testing and observation results. Utility Model Content

[0003] The technical problem solved by this invention is to provide a rapid soil testing device that prevents clogging, thereby addressing the issues raised in the background section.

[0004] The technical problem solved by this utility model is achieved by the following technical solution: a rapid soil detection device to prevent clogging, comprising:

[0006] The lower end of the platform is rotatably mounted with a snap-fit ​​shaft assembly, and the platform is equipped with a drive motor that drives the snap-fit ​​shaft assembly to rotate. A sampling cylinder for drilling soil is detachably installed under the snap-fit ​​shaft assembly.

[0007] The sampling cylinder includes a first cylinder plate and a second cylinder plate that can be closed. Both the first cylinder plate and the second cylinder plate have an arc-shaped structure. The upper ends of the first cylinder plate and the second cylinder plate are provided with rotating seats so that the first cylinder plate and the second cylinder plate can be rotated and connected to each other.

[0008] As a further embodiment of this utility model:

[0009] The platform includes a platform and a frame plate covering the outer end of the drive motor. The support frame includes a top plate and guide shafts distributed at the lower end of the top plate. Sliding sleeves are provided around the platform corresponding to the guide shafts, and the platform is slidably mounted on the guide shafts through the sliding sleeves. The screw jack is installed on the top plate, and the lower end of the screw of the screw jack is fixedly connected to the frame plate to control the lifting and moving of the platform.

[0010] As a further embodiment of this utility model:

The outer side of the lower end of the shaft platform is provided with an annular limiting sleeve plate, and the lower middle part of the shaft platform is provided with a circular limiting pin. A snap-fit ​​groove is provided between the limiting pin and the limiting sleeve plate to accommodate the first cylindrical plate and the second cylindrical plate, so that the first cylindrical plate and the second cylindrical plate can be inserted into the snap-fit ​​groove to prevent the first cylindrical plate and the second cylindrical plate from unfolding.

The sampling cylinder is detachably mounted on the shaft platform, allowing personnel to remove it and unfold the first and second cylinder plates to observe and test the soil within. This avoids soil clogging of the sampling cylinder and prevents damage to soil layers, facilitating subsequent testing and observation. Attached Figure Description

The lower outer side of the shaft platform 42 is provided with an annular limiting sleeve 43, and the lower middle part of the shaft platform 42 is provided with a circular limiting pin 44. A snap-fit ​​groove 45 for accommodating the first cylindrical plate 51 and the second cylindrical plate 52 is provided between the limiting pin 44 and the limiting sleeve 43, so that the first cylindrical plate 51 and the second cylindrical plate 52 can be inserted into the snap-fit ​​groove 45 to prevent the first cylindrical plate 51 and the second cylindrical plate 52 from unfolding.

[0032] A first threaded hole 46 is provided between the limiting pin 44 and the limiting sleeve 43. A second threaded hole 53 is provided on the first cylinder plate 51 and the second cylinder plate 52 respectively. A bolt 6 is provided on the shaft platform 42 to pass through the first threaded hole 46 and the second threaded hole 53, so as to install the sampling cylinder 5 on the shaft platform 42 and rotate with the shaft platform 42 to take soil.
