Description
Technical Field

[0002] Geochemistry is the study of the Earth's chemical composition, chemical reactions, and chemical evolution. It is a frontier discipline that emerged and developed through the integration of geology, chemistry, and physics. Since the mid-1970s, geochemistry, along with geology and geophysics, has become the three pillars of solid Earth science. Its scope of research has also expanded from Earth to the Moon and other celestial bodies in the solar system. Geochemical theories and methods are of great significance to the exploration, evaluation, and development of mineral resources, agricultural development, and environmental science.
[0003] For example, a soil sampling device for geochemical exploration with the authorization announcement number "CN214502978U" solves the problem of multi-position sampling operations in existing soil sampling devices for geochemical exploration, which affects the results of subsequent soil testing. The sampling tubes on both sides of the threaded sleeve slide down along the screw with the threaded sleeve, so that the sampling tubes take samples. The distance between the two groups of sampling tubes is small, so the difference in soil quality of the sampled soil is small. Therefore, the data of the two groups of soil tests can be compared and analyzed, which improves the accuracy of the test. The sampling is driven by a motor, which improves the efficiency of soil sampling and saves time and labor. Considering that the existing soil sampling device for geochemical exploration is limited by the length of the sampling tube, the depth of the sampling tube inserted into the soil for sampling is limited, resulting in a limitation of the soil sampling range.

DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] Example 1:
[0021] See also Figure 1-6 : In this embodiment, a soil sampling device for geochemical exploration includes an outer tube 1 and a handle 2. The lower end of the outer tube 1 is fixedly connected to the fixed ring 3, the outer wall of the fixed ring 3 is fixedly connected to the pedal 4, the upper end of the outer tube 1 is fixedly connected to the mounting ring 5, and the inner wall of the mounting ring 5 is connected to the displacement mechanism 6.
[0022] The displacement mechanism 6 includes a hydraulic cylinder 601. The hydraulic cylinder 601 is extended and retracted to drive the connecting plate 602 to move, so that the connecting plate 602 drives the first semicircular ring 603 to move. The outer wall of the hydraulic cylinder 601 is fixedly connected to the mounting ring 5. The model of the hydraulic cylinder 601 is determined according to actual needs and can meet the working requirements. The output end of the hydraulic cylinder 601 is fixedly connected to the connecting plate 602, and the end of the connecting plate 602 is fixedly connected to the first semicircular ring 603. The inner wall of the first semicircular ring 603 is tightly abutted against the pin 604.
[0023] Unplug the fixing rod 7, remove the handle 2 at the upper end of the connecting rod 801, and use the fixing rod 7 to splice and extend the length of the connecting rod 801. The pin 604 passes through the first semicircular ring 603 and the second semicircular ring 10 and is clamped into the groove 9 on the connecting rod 801. The hydraulic cylinder 601 contracts up and down, and the first semicircular ring 603 and the second semicircular ring 10 drive the connecting rod 801 to move, so that the connecting rod 801 pushes the sampling tube 803 on the square rod 802 to sample deep soil. The soil sampling range is limited, and the soil sampling range is expanded.
[0024] The inner wall of the handle 2 is movably connected to the fixed rod 7, and the outer wall of the fixed rod 7 is connected to the sampling mechanism 8. The sampling mechanism 8 includes a connecting rod 801, which helps push the sampling tube 803 on the square rod 802 to move, so that the sampling tube 803 can enter the soil at different depths to sample the soil. The inner wall of the connecting rod 801 is tightly pressed against the fixed rod 7, and the end of the connecting rod 801 is fixedly connected to the square rod 802, and the end of the square rod 802 is tightly pressed against the sampling tube 803.
[0025] The outer wall of the connecting rod 801 is processed with a groove 9, the outer wall of the groove 9 is tightly pressed against the first semicircular ring 603, the inner wall of the first semicircular ring 603 is movably connected to the second semicircular ring 10, the inner wall of the second semicircular ring 10 is tightly pressed against the pin 604, and the upper end of the connecting rod 801 is processed with a connecting groove 11.
[0026] Working principle:
[0027] When soil sampling is needed for geochemical exploration, the fixing ring 3 at the lower end of the outer cylinder 1 is placed into the upper end of the sampling, and the foot is stepped on the pedal 4 to fix the position of the outer cylinder 1. The connecting rod 801 is pushed through the handle 2 to push the sampling tube 803 on the square rod 802 into the interior of the soil, so that the soil enters the sampling tube 803, and the sampling tube 603 obtains the effect of soil sampling. At the same time, the fixing rod 7 is pulled out, and the handle 2 at the upper end of the connecting rod 801 is removed, so that the other connecting rod 801 of the same type is inserted into the connecting groove 11, and the fixing rod 7 is inserted into the connecting rod 801 for fixing, so that the length of the connecting rod 801 is extended and spliced. The semicircular ring 603 and the second semicircular ring 10 are docked with the groove 9 on the connecting rod 801, and the control pin 604 passes through the first semicircular ring 603 and the second semicircular ring 10 to fix the position, and the hydraulic cylinder 601 is turned on to work. The hydraulic cylinder 601 drives the connecting plate 602 to retract up and down, and the connecting plate 602 drives the first semicircular ring 603, the second semicircular ring 10 and the connecting rod 801 to move, so that the connecting rod 801 pushes the sampling tube 803 on the square rod 802 to sample the soil deep inside. The soil at the upper end will enter the interior of the outer tube 1 from the sampling tube 803 and be discharged, so that the sampling tube 803 can sample the soil at different depths.
[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
