Description

Technical Field

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

[0002] Soil detection refers to the determination of representative values of factors affecting soil environmental quality to determine environmental quality and its change trend. Sometimes, in order to understand the pollution degree of soil, it is necessary to detect soils at different depths to understand the distribution of pollutants in the soil along the vertical direction. Soil sampling refers to the method of collecting soil samples, which includes sampling techniques and collecting profile soil samples. Before sampling, the profile should be renovated, cleaned, and the surface floating soil should be removed, and then samples should be taken layer by layer from the central typical part from top to bottom. Therefore, various soil sampling tools are usually used.

[0003] A Chinese patent discloses a deep soil detection sampling tool (authorization announcement number: CN219977814U). Through the cooperation between the motor, the cylinder, and the transmission mechanism, first, the cylinder can move up and down. Connect the fixed block to the rotating rod, and drive the rotation of the drill bit by rotating the fixed block to increase the excavation speed of the drill bit. When the transmission mechanism moves up and down, it will drive the cross block to move up and down, and control the positions of the drill bit and the cylinder through the up and down movement of the cross block, so that the cylinder does not need to be manually controlled, which is very convenient and solves the problem that the cylinder is difficult to pull out of the ground. However, according to sampling common sense, the sampling point is not the only area. Therefore, when multiple areas need to be sampled, it is necessary to manually lift the above sampling tool and move it to another sampling point for sampling. Repeating this process will inevitably be time-consuming and laborious, affecting the sampling efficiency. Content of the Utility Model

Then, hold the threaded rod 315 and rotate it forward and backward. At this time, the telescopic plate 312 can be driven to move left and right in the hollow plate 311. When the telescopic plate 312 moves to the ideal position, stop rotating the threaded rod 315. Then, control the servo motor 33 to rotate forward and backward. At this time, the first gear 34, the second gear 35, and the limiting cylinder 31 can be driven to rotate forward and backward until the drill rod 39 moves to the ideal sampling point. Then, control the electric push rod 36 and the motor 38 to work. At this time, by continuously extending the electric push rod 36, the rotating drill rod 39 can be driven to continuously penetrate into the soil, thereby completing the sampling. After the sampling is completed, control the motor 38 to stop working, and then control the electric push rod 36 to shorten. At this time, the drill rod 39 can be driven to move out of the soil, thus completing the entire sampling process.
