Description

Technical Field

[0001] The utility model relates to the technical field of soil monitoring, in particular to a soil monitoring rapid sampling device. Background Art

[0002] Soil environmental monitoring refers to determining environmental quality (or pollution levels) and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Soil monitoring, as we commonly refer to it, generally includes technical aspects such as sampling, sample preparation, analytical methods, result presentation, data statistics, and quality evaluation.

[0003] A quick soil sampling device with the publication number CN 212903951 U has been found, comprising a drive motor fixing plate, a power source structure mounted on the upper wall of the drive motor fixing plate, a sampling tube structure mounted on the lower wall of the power source structure, a support structure mounted on the lower wall of the drive motor fixing plate, and a fixing structure mounted on the lower wall of the support structure. The power source structure comprises a drive motor, a sampling tube connecting shaft, a fixing bolt, and a fixing nut. The drive motor is mounted on the upper wall of the drive motor fixing plate, the sampling tube connecting shaft is mounted on the lower wall of the drive motor, the fixing bolt is mounted on the lower wall of the sampling tube connecting shaft, and the fixing nut is mounted on the front wall of the fixing bolt. Compared with traditional sampling methods, this device can penetrate the soil faster when sampling deeper or harder soil, thereby improving soil sampling efficiency. After sampling, it can ensure the integrity of the sampled soil, reduce the impact on soil test results, and improve test accuracy.

[0004] However, the above sampling device still has some shortcomings during use. For example, it is inconvenient to remove the sampled soil from the sampling tube, which makes the operation of removing the soil from the sampling tube troublesome, time-consuming and labor-intensive. At the same time, during sampling, as the sampling tube descends, the soil on the upper part will accumulate and fill the interior of the sampling tube, resulting in the inability of deep soil to enter the interior of the sampling tube for sampling. It is impossible to sample the soil at a specified depth, which is inconvenient to use. Utility Model Content

At the same time, during sampling, as the sampling tube descends, the soil on the upper part will accumulate and fill the interior of the sampling tube, resulting in the inability of deep soil to enter the interior of the sampling tube for sampling, and the inability to sample the soil at a specified depth, which is inconvenient to use.

[0006] The utility model provides the following technical solution: a soil monitoring rapid sampling device, comprising a support frame, a threaded rod rotatably connected between the top wall and the bottom wall of one side of the support frame, a threaded sleeve being threadedly sleeved on the surface of the threaded rod, a sliding rod being fixedly connected between the top wall and the bottom wall of the other side of the support frame, a sliding sleeve being slidably sleeved on the surface of the sliding rod, a connecting plate being fixedly connected between the sliding sleeve and the threaded sleeve, a sampling tube being rotatably sleeved on the connecting plate, a threaded hole being opened on the upper surface of the sampling tube, a screw rod being threadedly sleeved on the internal thread of the threaded hole, and a push plate being rotatably connected to one end of the screw rod located inside the sampling tube, a first motor being fixedly connected to the upper surface of one side of the support frame, and an output end of the first motor passing through the connected support frame and fixedly connected between the top end of the threaded rod.

[0008] Preferred technical solution 2: Two limit grooves are provided on the upper surface of the sampling tube, and limit rods are slidably sleeved inside the two limit grooves. The two limit rods are located inside the sampling tube and one end is fixedly connected to the push plate.
