Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a soil sampling cylinder. Background Technique

[0002] During engineering geological detection, it is necessary to conduct investigations on the natural conditions, genetic types, physical and chemical properties, fertility, distribution, and improvement and utilization methods of soil distribution. Soil general surveys require soil sampling and analysis. Most current mine geological samplings use some simple sampling cylinders. The implementation method is to press the sampling cylinder into the soil layer manually to obtain soil, and then collect and analyze the components of the taken soil to determine the composition, age, and thickness of the soil layer, etc.

[0003] The existing device mainly samples soil by inserting a sampling cylinder into the ground. Most of the existing technologies are similar to a soil sampling cylinder for engineering geological detection. The structure of the patent No. CN219675514U includes a mounting seat and a sampler for obtaining soil samples, and also includes a driving mechanism for controlling the sampler to insert into the soil. The driving mechanism includes a driving rod, and the driving rod is connected to the sampler; a second cylinder body, the second cylinder body is provided with a second driving cavity, and the second driving cavity is provided with a lifting control component and a rotation control component. This utility model enables the sampler to be more conveniently inserted into the soil with harder texture, thereby improving the hole-opening ability of the sampler for the soil and further improving the sampling efficiency. However, there are still areas for optimization in this device.

[0004] The existing device mainly controls the rotation and lifting of the sampling cylinder through two sets of power components, making it difficult for some devices to drive the sampling cylinder to rotate and lift stably, resulting in difficulty for some devices to drive the sampling cylinder deep into the ground. At the same time, some devices mainly use an open-type sampling cylinder, making it difficult for some devices to control the position of the drill bit inside the sampling cylinder, resulting in difficulty in controlling soil sampling and discharging, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a soil sampling cylinder is proposed. Content of the Utility Model
