Description

Technical Field

[0001] This utility model relates to the field of diamond sampling technology, specifically to a sampling device for diamond micron particle size analysis. Background Technology

[0002] Diamond micron powder has high hardness and good wear resistance, and can be widely used in cutting, grinding, drilling, polishing, etc. It is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, and optical glass. Sample collection is required when performing powder particle diameter analysis.

[0003] The utility model patent with authorization announcement number CN221649934U discloses a diamond micron powder particle size analysis sampler, which includes an upper straight tube, a limiting tube, and a lower straight tube arranged from top to bottom, and an external push rod. The lower end of the external push rod is fixedly connected to a pressure cap, and the lower side of the pressure cap is fixedly connected to an internal push rod. The internal push rod passes through the upper straight tube, the limiting tube, and the lower straight tube from top to bottom. The limiting tube is provided with a limiting hole for limiting the linear movement of the internal push rod. A return spring is provided between the limiting tube and the pressure cap. The lower end of the internal push rod is threadedly connected to a positioning block. Three fixing rods are fixedly connected to the side of the positioning block. The ends of the three fixing rods away from the positioning block are fixedly connected to a material hopper. The outer diameter of the upper end of the material hopper is smaller than the outer diameter of the lower straight tube.

[0004] As shown in the above-described utility model, existing diamond micron powder particle size analyzer samplers work by pushing an external push rod and inserting the hopper into the material, allowing the hopper to collect the sample. After releasing the external push rod, a return spring drives the hopper into the lower straight tube, sealing the sample and preventing spillage. However, existing devices lack a structure for conveniently controlling the sample volume, making it difficult to accurately control the amount of micron powder in the hopper during sampling, potentially resulting in either too much or too little sample. Too much sample leads to waste; too little sample may not meet the particle size analysis requirements, necessitating resampling and reducing work efficiency. Utility Model Content

[0018] 2. This sampling device for diamond micron powder particle size analysis uses a convex plate to drive the movable column, making it easy to operate. The movable column can move stably and automatically reset with the cooperation of springs and sliding grooves. At the same time, the sampling amount can be controlled by moving the extraction rod by the handle. The piston moves in the piston groove to generate negative pressure to extract micron powder, which can accurately control the amount of micron powder entering the sampling groove. After sampling, the movable column resets and is hidden in the storage cylinder. The movable cover automatically closes the lower opening of the channel to prevent sample spillage and contamination. The entire sampling process is convenient and can effectively control the sampling amount and ensure sample quality. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-4 The present invention provides the following technical solution:

[0026] A sampling device for diamond micron powder particle size analysis includes a storage component 1, a sampling component 2, and an extraction component 3.

[0027] Specifically, the storage component 1 includes a storage cylinder 11, which has a through groove 12 for hiding the material taking component 2. The storage cylinder 11 has a through groove 12 in the middle, and a sliding groove 13 in the middle of the through groove 12. Extension plates 15 are fixed on both sides of the top of the storage cylinder 11. The bottom of the storage cylinder 11 is connected to a movable cover 14 by a hinge and a torsion spring. The movable cover 14 is located outside the bottom opening of the through groove 12.

[0028] Specifically, the material taking component 2 is located in the through groove 12 in the middle of the storage cylinder 11, and the middle part of the material taking component 2 is connected to the storage cylinder 11 through a reset mechanism. The bottom of the material taking component 2 is provided with a sample placement mechanism for storing samples. The inside of the material taking component 2 is provided with a slot for placing the extraction component 3. The material taking component 2 includes a movable column 21 inserted into the through groove 12. A slider 22 is fixed on the outer side of the middle part of the movable column 21. The slider 22 is located in the slide groove 13 and plays a guiding and limiting role to prevent the movable column 21 from separating from the storage cylinder 11. The bottom of the slider 22 is connected to the inner bottom wall of the slide groove 13 through a spring 23 sleeved on the outer side of the movable column 21. The spring 23 enables the movable column 21 to automatically move after movement. The movable column 21 is reset, and a protruding plate 24 is fixed on the top. The slot inside the movable column 21 is composed of a piston slot 25 and a sampling slot 27. The piston slot 25 and the sampling slot 27 are separated by a filter screen 26, which can prevent diamond particles from entering the sampling slot 27 and then entering the piston slot 25. The upper circumference of the sampling slot 27 is provided with multiple feed holes 28 arranged in a ring array. The inner wall of the lower opening of the sampling slot 27 is provided with internal threads. A sealing block 29 is provided below the sampling slot 27. A stud 210 is fixed on the top of the sealing block 29. The stud 210 is adapted to the internal thread at the opening of the sampling slot 27 to seal the opening of the sampling slot 27, so that the sample in the sampling slot 27 can be easily taken out.

[0029] More specifically, the extractor 3 is set in the slot on the material receiving component 2. The extractor 3 draws diamond micro powder into the sample placement mechanism by negative pressure adsorption. The extractor 3 includes an extractor rod 31 set in the piston groove 25. A piston 32 is fixed at the bottom end of the extractor rod 31, and a handle 33 is fixed at the top of the extractor rod 31.

[0030] In use, the device first moves the movable column 21 via the protruding plate 24 until the lower end of the movable column 21 pushes open the movable cover 14 and protrudes from the storage cylinder 11. At this point, the feed hole 28 at the lower end of the movable column 21 is exposed. Then, the movable column 21 is inserted into the diamond microparticle container. Next, the handle 33 moves the extraction rod 31, which in turn moves the piston 32 within the piston groove 25. The resulting negative pressure draws the diamond microparticles into the sampling groove 27 through the feed hole 28. The filter screen 26 prevents the diamond microparticles from entering the piston groove 25. After sampling, the sample is collected. After completion, release the convex plate 24. At this time, the movable column 21 is reset under the action of the spring 23, and the movable column 21 is hidden in the through groove 12 on the storage cylinder 11. At the same time, the movable cover 14 is reset under the action of the torsion spring, and the lower end opening of the through groove 12 is closed. This prevents the sample from spilling after sampling and also prevents the sample from being contaminated by external impurities. When in use, extend the movable column 21 and then rotate the sealing block 29 until the stud 210 at the top of the sealing block 29 is separated from the sampling groove 27. At this time, the sample in the sampling groove 27 can be taken out for use.
