Description

Technical Field

[0001] This utility model relates to a sampling device, specifically a soil sampling device for mining geological engineering, belonging to the field of soil sampling technology for mining geological engineering. Background Technology

[0002] Soil sampling in mining geological engineering is a crucial step in obtaining information about underground soil layers, assessing geological conditions, and guiding subsequent engineering work. Its core purpose is to collect representative soil samples and analyze their physical, chemical, and mineral composition to provide a scientific basis for mine design, mining safety, and environmental remediation. Sampling is primarily conducted using a drilling rig with drill rods. The drilling rig is connected to a split pipe; after the drilling rig begins operation, the pipe shoe at the bottom of the split pipe makes a hole on the ground, allowing the split pipe to penetrate deep underground. The soil squeezed out inside is the corresponding geological soil sample.

[0003] However, currently, when sampling surface soil in mines using soil sampling drills, the split pipe is first fixed with a pipe shoe, and a pipe sleeve is connected to the other end of the split pipe. An impact connector is then threaded onto the pipe sleeve, and the impact connector is connected to the drill rig. After the drill rig is started, the pipe shoe drills into the ground to complete the sampling. The cylindrical soil samples are all collected inside the split pipe. After it is full, the split pipe needs to be opened to remove the soil sample, and another sample needs to be taken elsewhere. The sampled soil is placed inside a special storage box. The soil is not protected during transportation and is easily broken. The sampling data is generally written on the soil surface. The broken cylindrical soil sample needs to be pieced together again to read the data marked on the surface. If the sample is severely pulverized, it is easy to lose data. Utility Model Content

[0004] The purpose of this utility model is to provide a soil sampling device for mining geological engineering in order to solve the above problems. By setting an acrylic tube inside two split tubes to protect the soil sample and prevent it from breaking during transportation, the outer wall of the acrylic tube is provided with a marking mechanism to store paper data and prevent the loss of recorded data.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a soil sampling device for mining geological engineering, comprising a drilling rig, a connecting mechanism installed on the drilling rig, a protective mechanism installed on the connecting mechanism, the protective mechanism comprising two split tubes, two split tubes with arc-shaped cross-sections provided at the bottom of the connecting mechanism, connecting rings fixedly connected to both ends of the two split tubes, wherein two of the connecting rings are threadedly connected to the inside of the connecting mechanism, and drilling mechanisms are threadedly connected to the other two connecting rings, a marking mechanism is provided between the two split tubes, the marking mechanism comprising a fixing groove, fixing grooves being provided on the inner sides of the two split tubes, an acrylic tube being fastened between the two fixing grooves, a placement groove being provided on the surface of the acrylic tube, a protective cover being fastened to the placement groove, a locking hole being provided at the end of the protective cover, an insert rod being slidably connected inside the acrylic tube and inserted into the locking hole, and a spring being clamped between the insert rod and the acrylic tube.

[0006] Preferably, the connecting rings located at both ends of the two split tubes have an arc-shaped structure, and the two opposite connecting rings have a circular structure, and the thickness of the connecting ring is equal to half the thickness of the split tube.
