Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically a field geological exploration sampling device. Background Technology

[0002] In fieldwork such as geological exploration, mineral resource assessment, environmental surveys, and engineering geology, collecting representative rock, soil, or sediment samples is a crucial step. The quality of sampling directly affects the accuracy and reliability of subsequent laboratory analysis and testing data, thus influencing the scientific assessment of the geological conditions of the entire exploration area.

[0003] Traditional field geological exploration sampling often involves rotating and lowering a geological exploration sampling tube for sampling. After extraction, the geological exploration sample remains inside the sampling tube. The sample is usually manually extracted piece by piece by tapping the sampling tube, which is laborious and prone to causing sample breakage and disorder, affecting the accuracy of subsequent geological exploration sample testing. To address these issues, we propose a field geological exploration sampling device. Utility Model Content

[0023] Example: Figure 1-6 As shown, this utility model provides a field geological exploration sampling device, including a sampling tube body 1 and a material ejection mechanism 2. The material ejection mechanism 2 includes two symmetrically distributed outer frames 21. A fixing bolt 201 is threaded between the two outer frames 21 to fix the two outer frames 21. One end of the sampling tube body 1 is movably engaged with one end of the two outer frames 21 to connect the sampling tube body 1 and the material ejection mechanism 2. A positioning frame 211 is integrally formed at one end of the outer frame 21 near the sampling tube body 1. A fastening bolt 212 is threaded in the middle of the positioning frame 211. A positioning disc 213 is fixedly installed at the inner end of the fastening bolt 212. The positioning disc 213 is movably engaged in the positioning frame 211. The positioning disc 213 contacts the outer wall of the sampling tube body 1 and fixes the end of the sampling tube body 1 through the positioning disc 213. The outer frame 21 of the mechanism is fixedly fitted with an inner tube frame 22 in the middle. The inner side of the inner tube frame 22 is fixedly fitted with a threaded ring 23.

The push plate 25 is movably engaged in the inner tube frame 22. By controlling the movable screw 24 to rotate automatically, the movable screw 24 moves and controls the push plate 25 to move towards the sampling tube body 1. The push plate 25 automatically enters the sampling tube body 1 and automatically pushes out the sample in the sampling tube body 1. The sample can be taken out from the sampling tube body 1 without manual knocking, which saves time and effort. Moreover, the sample can be stopped by stopping the movement of the push plate 25, which facilitates sample placement and prevents sample breakage and confusion, which would affect the detection accuracy of subsequent geological exploration samples. A sealing ring 26 is fixedly fastened at one end of the inner tube frame 22 away from the push plate 25. A bearing 261 is fixedly installed in the middle of the sealing ring 26. A rotating outer frame 27 is fixedly installed in the middle of the bearing 261. A moving screw 24 moves through the middle of the rotating outer frame 27. A protrusion 271 is integrally formed on the inner side of the rotating outer frame 27. A groove 241 corresponding to the protrusion 271 is opened on the outer side of the moving screw 24. The protrusion 271 is slidably engaged in the groove 241. The moving screw 24 can easily slide in the rotating outer frame 27. A gear ring 28 is fixedly installed at the end of the rotating outer frame 27 away from the bearing 261. A gear 281 is meshed with the bottom of the gear ring 28. A drive shaft 282 is fixedly installed in the middle of the gear 281. An auxiliary seat 291 is installed at the bottom of the inner tube frame 22. The drive shaft 282 is rotatably mounted on the auxiliary seat 291. A drive motor 29 is fixedly installed on the auxiliary seat 291. The drive end of the drive motor 29 is fixedly installed with the shaft end of the drive shaft 282. By turning on the drive motor 29, the gear 281 is driven to rotate, thereby controlling the rotating outer frame 27 to drive the moving screw 24 to rotate automatically.

[0024] The movable screw 24 is fixedly installed with a mounting protrusion 242 near the push plate 25. The top of the push plate 25 is threaded with a mounting bolt 251. The mounting bolt 251 moves through the mounting protrusion 242 to fix the movable screw 24 and the push plate 25, thereby facilitating the disassembly of the movable screw 24 and the push plate 25. It can also replace the movable screw 24 with one of appropriate length according to the length of the sampling tube body 1 to push the push plate 25 to move, thereby discharging the sample in the sampling tube body 1, increasing the flexibility of the whole device.

[0025] The bottom end of the unloading mechanism 2 is provided with a first support seat 3. The top of the first support seat 3 is integrally formed with an installation protrusion 31. The bottom end of the outer frame 21 of the mechanism is provided with an installation groove 301. The installation protrusion 31 is movably engaged in the installation groove 301. The unloading mechanism 2 is supported by the first support seat 3.

[0026] The sampling tube body 1 is provided with multiple second support seats 4 below. The top of the second support seat 4 is integrally formed with a support frame 41. The sampling tube body 1 is movably placed on the support frame 41. The sampling tube body 1 is supported by the second support seats 4 with support frames 41.

[0027] Working principle: Before sampling, first install a movable screw 24 of appropriate length according to the length of the sampling tube body 1, thread the movable screw 24 onto the threaded ring 23 and slide it through the rotating outer frame 27, and fix the push plate 25 at one end of the movable screw 24 so that the push plate 25 is movably engaged in the inner tube frame 22. After the cylindrical sample is taken out from the sampling tube body 1, the sampling tube body 1 is movably placed on the support frame 41, and one end of the sampling tube body 1 is movably locked to one end of the two mechanism outer frames 21. The positioning plate 213 is moved by manually rotating the fastening bolt 212 with a tool so that the positioning plate 213 contacts the outer wall of the sampling tube body 1 and the end of the sampling tube body 1 is fixed by the positioning plate 213. Subsequently, the drive motor 29 drives the gear 281 to rotate the gear ring 28, thereby controlling the rotating outer frame 27 to automatically rotate the moving screw 24. The moving screw 24 moves the control push plate 25 to one side of the sampling tube body 1. The push plate 25 automatically enters the sampling tube body 1 and automatically pushes out the sample from the sampling tube body 1. The sample can be taken out from the sampling tube body 1 without manual tapping, saving time and effort. Moreover, the sample can be stopped by stopping the movement of the push plate 25, which facilitates sample placement and prevents sample breakage and disorder, thus affecting the accuracy of subsequent geological exploration sample testing.
