Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a rock blasting sampling device for mining geological collection. Background Technology

[0002] Mining geological sampling is the process of collecting samples from ore bodies, surrounding rocks, and mineral products according to specifications, and then processing, analyzing, testing, and identifying them. Its purpose is to study the quality of minerals, the physicochemical properties of ores and surrounding rocks, and to provide data support for mineral deposit assessment. To meet testing requirements, samples need to be processed through steps such as crushing, screening, mixing, and reduction. In order to enable low-cost and efficient mining of various types of mines, rock blasting technology is usually used. Rock blasting is a mechanical process that uses the explosive action of explosives to apply load to rocks, causing them to break.

[0003] Before blasting in a mine, it is usually necessary to sample and test the internal rock structure to determine the appropriate explosive type. Currently, for harder rocks, handheld sampling drills are mainly used for sampling. Handheld sampling drills are not only easy to carry but also adaptable to different ground conditions in the mine. However, in use, workers manually push the drill to move it. When extracting rock samples, workers still need to manually move the drill to move the samples. This method not only increases the labor intensity for workers but also results in low sampling efficiency. To further reduce the labor intensity for workers and improve the sampling efficiency, a rock blasting sampling device for mine geological collection is provided, which can eliminate the drawbacks of existing devices.

Double-layer core tube. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-3As shown, a rock blasting sampling device for mining geological collection includes a connecting seat 1. A motor 4 is installed at the top of the connecting seat 1. A double-layer core tube 5 is installed at the output end of the motor 4. The double-layer core tube 5 is located below the connecting seat 1. A core cutter for cutting off the core and sealing the tube opening is installed on the double-layer core tube 5. Two handles 3 are symmetrically fixedly connected to the top of the connecting seat 1. The two handles 3 are located on both sides of the motor 4. A reset mechanism for pushing the connecting seat 1 to a stable reset is provided on the connecting seat 1.

[0030] The reset mechanism includes: a guide assembly disposed on the connecting seat 1;

[0031] The guide assembly includes two limiting slide rods 204 symmetrically arranged at the bottom of the connecting seat 1. Both limiting slide rods 204 extend to the outside of the top of the connecting seat 1. Both limiting slide rods 204 are slidably connected to the connecting seat 1. The two limiting slide rods 204 are located on both sides of the double-layer core tube 5.

[0032] A lifting assembly is provided below the connecting base 1;

[0033] In this embodiment, when in use, the bottom end of the double-layer core tube 5 is placed at the designated position by holding the handle 3, then the handle 3 is started to rotate the double-layer core tube 5, and then the handle 3 is pushed to make the double-layer core tube 5 perform a sampling operation on the rock.

[0034] During this process, the connecting seat 1 gradually descends as the double-layer core tube 5 rotates. At the same time, the limiting slide bar 204 can gradually rise along the inner wall of the connecting seat 1 as the connecting seat 1 descends through the reset mechanism. Thus, the height of the connecting seat 1's descent can be clearly determined by the moving limiting slide bar 204, so that the sampling depth of the rock sample can be viewed in real time.

[0035] When the connecting seat 1 descends to the designated height, the above operation is reversed by the reset mechanism. This allows the double-layer core tube 5 to rise steadily by pushing the connecting seat 1. At the same time, the double-layer core tube 5 moves the rock sample synchronously through the core clamp until the connecting seat 1 is fully reset. This can further reduce the labor intensity of workers and effectively improve the sampling efficiency of rock samples.

[0036] In one embodiment, such as Figures 1-3 As shown, the lifting assembly includes: a first lifting ring 207 located outside the double-layer core tube 5, and two connecting plates 206 symmetrically fixedly connected to the outer wall of the first lifting ring 207. The two connecting plates 206 are respectively located at the bottom ends of the two limiting slide rods 204, and the two connecting plates 206 are respectively fixedly connected to the two limiting slide rods 204.

[0037] A limit component is provided on the first lifting ring 207;

[0038] The limiting component includes: a second lifting ring 208 located outside the double-layer core tube 5, the second lifting ring 208 being located inside the first lifting ring 207, and multiple fixing plates 205 being fixedly connected circumferentially at equal intervals to the outer wall of the second lifting ring 208, and all the multiple fixing plates 205 being fixedly connected to the first lifting ring 207.

[0039] A rolling component is provided on the second lifting ring 208;

[0040] The rolling assembly includes multiple balls 209 circumferentially and equidistantly connected to the inner wall of the second lifting ring 208. All balls 209 are in contact with the outer wall of the double-layer core tube 5. Through the cooperation of the lifting assembly and the limiting assembly, the limiting slide bar 204 can move in the opposite direction as the connecting seat 1 rises and falls, so as to clearly determine the height of the lowering of the connecting seat 1. At the same time, the balls 209 can effectively reduce the friction between the second lifting ring 208 and the double-layer core tube 5.

[0041] A telescopic assembly is provided on the connecting plate 206;

[0042] In one embodiment, such as Figures 2-3 As shown, the telescopic component is a bellows 2010 fixedly connected to the top of the connecting plate 206. The bellows 2010 is sleeved on the outer wall of the limiting slide bar 204, and the bellows 2010 is fixedly connected to the connecting seat 1.

[0043] An inflation component is provided on the connecting base 1;

[0044] The inflation assembly includes: a support plate 201 fixedly connected to one end of the connecting seat 1, an air pump 2013 installed at the top of the support plate 201, and a first air supply pipe 2011 fixedly connected to the output end of the air pump 2013.

[0045] An air delivery assembly is provided on the support plate 201;

[0046] The gas delivery assembly includes: a first gas delivery pipe 2011 fixedly connected to the output end of the air pump 2013, the first gas delivery pipe 2011 being located below the support plate 201; a second gas delivery pipe 2012 fixedly connected to the bottom end of the first gas delivery pipe 2011; two connecting pipes 203 symmetrically fixedly connected to one end of the second gas delivery pipe 2012, the two connecting pipes 203 being located outside the two limiting slide rods 204 respectively; the connecting pipes 203 being fixedly connected to the corrugated pipe 2010; and the inner cavity of the second gas delivery pipe 2012... The corrugated pipe 2010 and the inner cavity of the first gas supply pipe 2011 are interconnected. A sealing ring 202 is fixedly connected to the inner wall of the corrugated pipe 2010. The sealing ring 202 is sleeved on the outer wall of the limiting slide rod 204. The sealing ring 202 is located above one end of the second gas supply pipe 2012. Through the cooperation between the telescopic component, the inflation component and the gas supply component, the connecting seat 1 can be automatically reset by inflation. This can further reduce the labor intensity of workers and effectively improve the sampling efficiency of rock samples.

[0047] The above embodiment discloses a rock blasting sampling device for mining geological collection. In use, the bottom end of the double-layer core tube 5 is placed at a designated position by holding the handle 3. Then, the handle 3 is activated to rotate the double-layer core tube 5. At this time, multiple ball bearings 209 effectively reduce the friction between the second lifting ring 208 and the double-layer core tube 5. Then, the handle 3 is pushed to make the double-layer core tube 5 perform a rock sampling operation.

[0048] During this process, the connecting seat 1 gradually descends as the double-layer core tube 5 rotates. At the same time, the first lifting ring 207, blocked by the ground, drives the second lifting ring 208 to slide and rise along the outer wall of the double-layer core tube 5 through multiple fixed plates 205. At this time, the limiting slide rod 204, driven by the first lifting ring 207 through the connecting plate 206, gradually rises along the inner wall of the connecting seat 1. Meanwhile, the corrugated pipe 2010 is compressed by the connecting plate 206 and shrinks by folding. At this time, the air in the inner cavity of the corrugated pipe 2010 is discharged to the outside through the connecting pipe 203, the second air supply pipe 2012, the first air supply pipe 2011, and the air pump 2013. Thus, the height of the descending of the connecting seat 1 can be clearly determined by the moving limiting slide rod 204, so that the sampling depth of the rock sample can be viewed in real time.

[0049] Once the connecting seat 1 descends to the designated height, the air pump 2013 is activated to reverse the above operation. This allows the connecting seat 1 to drive the double-layer core tube 5 to rise steadily. Simultaneously, the double-layer core tube 5 moves the rock sample synchronously through the core clamp until the connecting seat 1 is fully reset. This further reduces the labor intensity of workers and effectively improves the sampling efficiency of rock samples.

[0050] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
