Description

Technical Field

[0001] This utility model relates to the field of geological exploration and sampling technology, and in particular to a sampler for mine geological exploration. Background Technology

[0002] In mining geological exploration, core sampling is a crucial step in obtaining the physical and mechanical properties and compositional characteristics of underground rock strata. Traditional core sampling methods typically rely on manual operation or simple mechanical devices, making it difficult to guarantee the integrity and accuracy of the samples. With the continuous development of geological exploration technology, higher demands are placed on the cutting precision, fixation stability, and operational efficiency of core samples. Therefore, there is an urgent need for specialized equipment capable of efficiently and accurately separating core samples to meet the exploration needs under complex geological conditions and provide reliable data support for subsequent experimental analysis.

[0003] Currently, most common core samplers use manual clamping or single-point fixing methods, and use screws or spring mechanisms to initially fix the core. For example, some devices use a rotating handle to drive the screw to advance the clamping block, so that the core is clamped between two sets of V-grooves. Other devices use the elastic force of the spring to provide clamping force, and use simple guide rails to adjust the cutting position.

[0004] However, in actual use, the above-mentioned samplers are prone to shaking or shifting due to the clamping mechanism relying only on single-point or unidirectional fixation. This results in uneven cutting surfaces and large deviations in the length of the sampled parts. Therefore, a sampler for mining geological exploration is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sampler for mining geological exploration, which aims to improve the problem that the core is easily shaken or shifted during the cutting process due to the clamping mechanism relying only on single-point or unidirectional fixation, resulting in uneven cutting surface and large deviation in sample length.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampler for mining geological exploration, comprising a base, a fixing block and a cutting box fixedly connected to the upper surface of the base, a protective plate and a motor fixedly connected to the inner wall of the cutting box, a cutting blade fixedly connected to the output end of the motor, a discharge pipe fixedly connected to the inner wall of the cutting box, a connecting block and a second connecting block fixedly connected to the outer wall of the discharge pipe, a conveying pipe fixedly connected to the outer wall of the second connecting block, a connecting block and a first connecting block fixedly connected to the outer wall of the conveying pipe, an inlet pipe fixedly connected to the outer wall of the first connecting block, a hydraulic cylinder fixedly connected to the inner wall of the first fixing block, a connecting plate fixedly connected to the output end of the hydraulic cylinder, and a clamping assembly provided on the outer wall of the connecting plate;

[0007] The clamping assembly includes a second fixing block, a third fixing block, and a clamping block. The inner wall of the second fixing block is fixedly connected to the outer wall of the connecting plate. The outer wall of the third fixing block is rotatably connected to the inner wall of the second fixing block. The outer wall of the clamping block is rotatably connected to the inner wall of the third fixing block.

[0008] Furthermore, a connecting rod is rotatably connected to the inner wall of the clamping block, and a connecting block three is fixedly connected to the outer wall of the connecting rod.

[0009] Furthermore, a buffer block is fixedly connected to the outer wall of the base, and a collection box is fixedly connected to the upper surface of the base.

[0010] Furthermore, a fan is installed on the outer wall of the collection box, and a second suction pipe is fixedly connected to the output end of the fan.

[0011] Furthermore, the outer wall of the second suction pipe is fixedly connected to the inner wall of the collection box, and the inner wall of the collection box is fixedly connected to the first suction pipe.

[0012] Furthermore, the outer wall of the suction pipe is fixedly connected to the inner wall of the cutting box, and a filter plate is slidably connected to the inner wall of the collection box.

[0013] Furthermore, a drawer is slidably connected to the inner wall of the collection box, and a dust cover is fixedly connected to the inner wall of the drawer.

[0014] Furthermore, the fan is positioned above the base and on one side of the outer wall of the cutting box.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, a hydraulic cylinder drives a connecting plate to rotate fixed blocks two and three, causing the clamping block to tightly hold the rock core. The connecting rod on the connecting block three forms a multi-directional fixation for the clamping block, effectively preventing the rock core from shaking or shifting during the cutting process. This solves the problems of uneven cutting surfaces and large deviations in sample length caused by unstable rock core fixation in traditional samplers, ensuring that the sampled samples can accurately reflect the original physical and mechanical properties and compositional characteristics of the rock core, providing a reliable sample basis for mine geological exploration.

[0017] In this invention, the dust generated during the cutting process enters the collection box through the fan and suction pipe. The filter plate intercepts larger stone particles, and the dust settles in the drawer for easy cleaning. The dust cover inside the drawer effectively prevents dust from entering the fan, avoiding wear and blockage of the fan components. This not only reduces the harm of dust to the operator's respiratory system but also lowers the probability of equipment failure due to dust accumulation, improving the durability and operational safety of the equipment. At the same time, the buffer block on the base absorbs the vibration generated by the motor and equipment operation through elastic deformation, reducing the impact of vibration on cutting accuracy.

[0025] 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.

[0026] Reference Figure 1 - Figure 4This utility model provides an embodiment of a sampler for mine geological exploration, comprising a base 1, with a fixing block 3 and a cutting box 5 fixedly connected to the upper surface of the base 1. The cutting box 5 isolates the cutting process from the external environment, preventing rock chips generated during cutting from splashing outside the equipment, and at the same time provides a relatively enclosed space for the dust collection pipe 10 to collect dust, improving dust collection efficiency. A protective plate 6 and a motor 9 are fixedly connected to the inner wall of the cutting box 5, with a cutting blade 25 fixedly connected to the output end of the motor 9. A discharge pipe 7 is fixedly connected to the inner wall of the cutting box 5. A connecting block 2 17 is fixedly connected to the outer wall. A conveying pipe 4 is fixedly connected to the outer wall of the connecting block 2 17. A connecting block 1 16 is fixedly connected to the outer wall of the conveying pipe 4. An inlet pipe 2 is fixedly connected to the outer wall of the connecting block 1 16. The inlet pipe 2 is used to guide the rock core into the equipment, so that the rock core can slide smoothly to the clamping position. At the same time, it plays a preliminary positioning role for the rock core and prevents the rock core from shifting when entering the equipment. A hydraulic cylinder 18 is fixedly connected to the inner wall of the fixing block 1 3. A connecting plate 23 is fixedly connected to the output end of the hydraulic cylinder 18. A clamping component is provided on the outer wall of the connecting plate 23.

[0027] The clamping assembly includes a second fixing block 20, a third fixing block 21, and a clamping block 22. The inner wall of the second fixing block 20 is fixedly connected to the outer wall of the connecting plate 23. The outer wall of the third fixing block 21 is rotatably connected to the inner wall of the second fixing block 20. The outer wall of the clamping block 22 is rotatably connected to the inner wall of the third fixing block 21. The clamping block 22 moves closer to or further away from each other under the action of the second fixing block 20 and the third fixing block 21. When it moves closer, it can tightly clamp the rock core to prevent the rock core from shaking or shifting during the cutting process and to ensure cutting accuracy. When it moves further away, it releases the rock core after cutting. The inner wall of the clamping block 22 is rotatably connected to a connecting rod 24, and the outer wall of the connecting rod 24 is fixedly connected to a third connecting block 19.

[0028] Reference Figure 1 - Figure 5A buffer block 8 is fixedly connected to the outer wall of the base 1, and a collection box 11 is fixedly connected to the upper surface of the base 1. A fan 12 is installed on the outer wall of the collection box 11, and a second suction pipe 13 is fixedly connected to the output end of the fan 12. The outer wall of the second suction pipe 13 is fixedly connected to the inner wall of the collection box 11, and a first suction pipe 10 is fixedly connected to the inner wall of the collection box 11. The first suction pipe 10 serves as a dust conveying channel. Under the suction force of the fan 12, the dust generated during cutting in the cutting box 5 is introduced into the collection box 11 to prevent the dust from spreading into the air. The outer wall of the first suction pipe 10 is fixedly connected to the inner wall of the cutting box 5, and the inner wall of the collection box 11 is slidably connected. A filter plate 14 is connected to the dust, which can intercept larger stone particles and rock chips in the dust and prevent them from entering the drawer 15 or the fan 12. This avoids the impact of larger particles on the cleaning of the drawer 15 and the operation of the fan 12. The drawer 15 is slidably connected to the inner wall of the collection box 11. A dust cover 26 is fixedly connected to the inner wall of the drawer 15. The dust cover 26 prevents the dust in the drawer 15 from entering the fan 12 under the suction of the fan 12, avoiding the dust from causing wear or blockage to the impeller of the fan 12 and extending the service life of the fan 12. The fan 12 is located above the base 1 and on one side of the outer wall of the cutting box 5.

[0029] Working principle: When it is necessary to cut and sample the rock core, the rock core is first placed into the feed pipe 2. The hydraulic cylinder 18 is started to push the connecting plate 23 to slide, which drives the fixing block 20 and the fixing block 3 21 to rotate at a certain angle, so that the clamping block 22 tightly clamps the rock core. During this process, the connecting rod 24 on the connecting block 3 19 forms a multi-directional fixation for the clamping block 22 to prevent it from shifting. This effectively prevents problems such as uneven cutting surface and deviation in sample length caused by shaking during rock core cutting.

[0030] Subsequently, the core sample slides into the cutting box 5 through the conveying pipe 4. The motor 9 drives the cutting blade 25 inside the protective plate 6 to rotate at high speed, precisely cutting the core sample. The dust generated during cutting is sucked into the collection box 11 by the fan 12 through the suction pipe 10. Larger stone particles are intercepted by the filter plate 14, while the dust is deposited in the drawer 15. The drawer 15 can be slid out directly for cleaning. The dust cover 26 inside the drawer 15 can effectively prevent dust from entering the fan 12, avoiding damage to the equipment. At the same time, the buffer block 8 on the base 1 absorbs vibration through elastic deformation, reducing the vibration transmission of the motor 9 and the equipment during operation, further ensuring the accuracy of sample separation.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
