Description

Technical Field

[0001] This utility model relates to the field of geological sampling technology, specifically a rock sampling machine for the development of geological relics. Background Technology

[0002] In the field of geological heritage development, rock sampling is a crucial foundational task. Rock sampling is a prerequisite for in-depth research on the material composition, structure, formation age, and evolution process of geological heritage. By analyzing and testing the collected rock samples, a solid scientific basis can be provided for the study of the formation mechanism of geological heritage, the formulation of protection plans, and the design of development and utilization schemes.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 8 This utility model provides a rock sampling machine for geological heritage development; it includes a sampling frame, the sampling frame includes a base plate 1, a side plate 2 is fixedly connected to the edge of the base plate 1, a top plate 3 is fixedly connected to the top of the side plate 2, and a plurality of support cylinders 4 are fixedly connected between the top plate 3 and the base plate 1. like Figure 1 As shown, the base plate 1 and the top plate 3 are hollow and connected by the side plate 2. A push rod (shown in the figure, not labeled) is fixedly connected to the back of the side plate 2. A sleeve is fitted on the surface of the push rod. In order to facilitate the movement of the device, several casters 30 are provided at the bottom of the base plate 1. The device can be moved by holding the push rod, which improves the flexibility of the device.

[0019] The sampling component includes a driving component 5 located on the top plate 3 and the side plate 2. A motor 6 is located on the part of the driving component 5 away from the side plate 2. The output end of the motor 6 is fixedly connected to the sampling cylinder 7. A detachable limiting plate 8 is provided inside the bottom plate 1. A limiting hole 9 is opened on the surface of the limiting plate 8 for limiting the sampling cylinder 7. The lower surface of the base plate 1 is provided with equidistant limiting grooves 15. The limiting plate 8 includes docking blocks 16 arranged in a rectangular array on the side and threaded holes 17 opened on the upper surface of the docking blocks 16. The upper surface of the base plate 1 is provided with several fastening rods 18, and the bottom end of the fastening rods 18 extends into the interior of the threaded holes 17.

[0020] When disassembling the limiting plate 8, the fastening rod 18 can be rotated so that its bottom end is disengaged from the threaded hole 17. At this time, the limiting plate 8 can be disassembled for easy maintenance and cleaning. During installation, the mating block 16 is snapped into the inside of the limiting groove 15, and the fastening rod 18 is extended to the threaded hole 17 for fixation.

[0021] The driving component 5 includes a second motor 501 fixedly connected to the upper surface of the top plate 3. A screw 502 is fixedly connected to the output end of the second motor 501. A slide rail 14 is provided on the side of the side plate 2 near the bottom plate 1. The bottom end of the screw 502 passes through the slide rail 14 and extends into the interior of the bottom plate 1. A horizontal plate 503 is threadedly connected to the surface of the screw 502. The end of the horizontal plate 503 away from the screw 502 is located on the outer wall of the first motor 6. When motor 501 is started, it drives screw 502 to rotate. Since one end of horizontal plate 503 is threaded to the surface of screw 502, horizontal plate 503 moves up and down along screw 502, synchronously driving motor 6 and sampling cylinder 7 to move up and down. At this time, starting motor 6 drives sampling cylinder 7 to rotate, and sampling can be performed. Since limiting plate 8 has limiting hole 9 on its surface, when sampling cylinder 7 moves downward, sampling cylinder 7 can pass through limiting hole 9 to perform sampling. This can accurately limit sampling cylinder 7, reduce shaking of sampling cylinder 7 during sampling, ensure the integrity of the extracted rock sample, and avoid sample damage or sampling failure due to deviation.

[0022] The support includes a threaded cylinder 10 rotatably connected inside the support cylinder 4, a support column 11 disposed inside the threaded cylinder 10, the threaded cylinder 10 being rotatably connected inside the top plate 3 via a convex ring disposed on the top outer wall, the top end of the threaded cylinder 10 extending to a groove opened on the upper surface of the top plate 3, a support rod 12 being rotatably connected to the upper surface of the crossbar of the top plate 3, and an adjustment element 13 for cooperating with the threaded cylinder 10 being provided at the other end of the support rod 12. A rectangular block 19 is fixedly connected to the top surface of the threaded cylinder 10. A limiting cylinder 20 is fixedly connected to the upper surface of the crossbar of the top plate 3. One end of the support rod 12 is rotatably connected to the inside of the limiting cylinder 20. The adjusting component 13 includes an auxiliary cylinder 1301 located at the other end of the support rod 12. A moving block 1302 is located inside the auxiliary cylinder 1301. A motor 1303 is located inside the moving block 1302. A docking rod 1304 is fixedly connected to the output end of the motor 1303. A slot for cooperating with the rectangular block 19 is opened at the bottom end of the docking rod 1304. An auxiliary rod 1305 is fixedly connected to the top of the moving block 1302. A spring 1306 is sleeved on the outer wall of the auxiliary rod 1305. The top of the auxiliary rod 1305 passes through the auxiliary cylinder 1301 and the support rod 12 and is fixedly connected to a pull ball.

[0023] When supporting the equipment, hold the support rod 12 and rotate it along the top plate 3. When the auxiliary cylinder 1301 rotates to the groove, the spring 1306 can drive the moving block 1302 to extend to the groove. At this time, start the motor 1303 to drive the docking rod 1304 to rotate, so that the slot at its bottom end engages with the rectangular block 19. Use the rectangular block 19 to drive the threaded cylinder 10 to rotate. At this time, the internal support column 11 moves downward quickly, thus supporting the ground. When the auxiliary cylinder 1301 rotates again, stop the motor 1303, hold the pull ball and pull it upward, so that the docking rod 1304 moves upward and separates from the rectangular block 19. Hold the support rod 12 and rotate it again to repeat the above operation.

[0024] One end of the support rod 12 extends into the limit cylinder 20 and is fixedly connected to a vertical shaft 21. A belt 22 is fitted on the bottom surface of the vertical shaft 21. A dust collector 23 is fixedly connected to the side wall of the top plate 3. A fan 24 is installed inside the dust collector 23. A filter screen 25 is installed on the inner wall of the dust collector 23 and below the fan 24. The center of the lower surface of the filter screen 25 is inserted into the rotating rod 26. The other end of the belt 22 passes through the crossbar of the top plate 3, extends into the dust collector 23, and is fitted on the bottom surface of the rotating rod 26. A cleaning rod 27 is installed on the outer wall of the rotating rod 26 near the lower surface of the filter screen 25. A bent pipe 28 is fixedly connected to the bottom of the dust collector 23. An air inlet 29 is provided on the lower surface of the limiting plate 8. The bottom end of the bent pipe 28 is detachably connected to the side of the top connecting strip of the limiting plate 8 and communicates with the air inlet 29.

[0025] To reduce dust generated during sampling, the fan 24 can be turned on during sampling. At this time, suction is generated at the air inlet 29, and the generated dust enters the dust collector 23 through the bend 28, and is discharged after being filtered by the filter screen 25. After use, dust inevitably accumulates on the surface of the filter screen 25, causing blockage and affecting dust removal efficiency. To solve this problem, a cleaning rod 27 is provided on the outer wall of the rotating rod 26 near the surface of the filter screen 25. When the hand-held support rod 12 is rotated, the vertical shaft 21 is rotated synchronously, and the rotating rod 26 is rotated under the transmission of the belt 22. Since the cleaning rod 27 is fixed on its surface, the dust on the surface of the filter screen 25 can be cleaned when the cleaning rod 27 rotates, thus maintaining the dust removal efficiency.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0027] In this invention, the working steps of the device are as follows: When in use, push the sampler to the geological site sampling area by holding the push rod on the back of the base plate 1 and using the bottom moving wheels 30. Adjust the placement angle of the equipment according to the sampling position to ensure that the bottom of the sampling tube 7 corresponds to the surface of the rock to be sampled. Rotate the support rod 12 around the limiting cylinder 20 to move the adjusting component 13 to the groove at the top of the threaded cylinder 10. The spring 1306 pushes the moving block 1302 down, allowing the bottom slot of the docking rod 1304 to engage with the rectangular block 19 of the threaded cylinder 10. Start the motor 1303 to drive the docking rod 1304 to rotate, which in turn drives the threaded cylinder 10 to rotate through the rectangular block 19. This causes the support column 11 to extend downward from inside the threaded cylinder 10 and support the ground. Repeat the operation of the remaining support components to ensure the overall stability of the equipment. After completion, turn off the motor 1303 and pull the ball of the auxiliary rod 1305 upward to separate the docking rod 1304 from the rectangular block 19. Rotate the support rod 12 to reset. The starting motor 6 drives the sampling cylinder 7 to rotate, and at the same time the starting motor 501 drives the screw 502 to rotate, so that the horizontal plate 503 moves downward along the slide 14, driving the rotating sampling cylinder 7 to pass through the limiting hole 9 of the limiting plate 8, contact the rock surface and take a sample; during the sampling process, the fan 24 is started, and the dust generated during sampling is sucked into the dust collection cylinder 23 through the air inlet 29 and the bend pipe 28, and discharged after being filtered by the filter screen 25; After sampling is completed, reverse start motor 2 501 to raise sampling cylinder 7 and detach it from the rock, then turn off motor 1 6 and motor 2 501; turn off fan 24, hold support rod 12 and rotate it, drive rotating rod 26 and cleaning rod 27 to rotate through vertical shaft 21 and belt 22 to clean dust from the surface of filter screen 25; disassemble the connection between bent pipe 28 and limit plate 8, rotate fastening rod 18 to remove limit plate 8, and take out rock sample from sampling cylinder 7.

[0028] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
