Description

Technical Field

[0001] This utility model relates to the field of coal quality analysis, and in particular to a micro-coal sample dispensing hopper. Background Technology

[0002] In traditional coal quality analysis, whether industrial or elemental analysis, the first step is usually to manually weigh the coal sample. The weight of the coal sample for industrial analysis is typically 1g, while for elemental analysis it's less than 0.1g, with a deviation generally within 10%. Weighing minute quantities of samples requires high repeatability, is meticulous and tedious, and consumes a significant amount of time and effort.

[0003] Furthermore, since coal is non-uniform, it is almost impossible to take a small sample from non-uniform coal to represent the true quality of the coal, which can easily affect the analysis results. Therefore, it is necessary to control the weight of the coal sample before it is manually weighed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the problem that the unevenness of coal quality in the existing technology can easily affect the analysis results, and to provide a micro-coal sample dispensing hopper.

[0005] The technical solution adopted by this utility model to solve its technical problem is a micro-coal sample dispensing hopper, including a storage bin, a blocking block, a sample-dispensing rod, and a dispensing bin. The storage bin is embedded in the top of the dispensing bin and is coaxially arranged. The storage bin and the dispensing bin are hollow with openings at both ends. The dispensing bin is conical and has a discharge cone and a discharge opening. The discharge opening is located at the bottom of the discharge cone. The sample-dispensing rod is provided with stirring rake teeth, and multiple stirring rake teeth are provided and evenly distributed around the sample-dispensing rod in a circular pattern. The stirring rake teeth match the shape of the discharge cone. The bottom of the sample-dispensing rod blocks the discharge opening under the action of gravity. The blocking block is set inside the storage bin and abuts against the inside of the storage bin to block the coal.

[0006] Furthermore, the storage bin is divided into an inverted conical part and a cylindrical part, with the inverted conical part located at the top of the cylindrical part and the two parts being integrally formed.

[0007] Furthermore, a positioning pin hole is provided through the outer circumferential surface of the cylindrical part, and a positioning pin is placed in the positioning pin hole to limit the material block to its upper and lower positions.

[0008] Furthermore, the top of the sample-dispensing rod has a sample-dispensing slot, allowing for manual operation of the sample-dispensing rod to move the coal sample up and down.

[0009] Furthermore, it also includes an opening and closing mechanism, which is located on one side of the storage bin. The opening and closing mechanism includes a reset handle, a reset spring, a swing arm, and a sealing plate. A connecting plate is provided on one side of the distribution bin, and a through hole is provided on the connecting plate. The swing arm is fitted into the through hole by a bearing to achieve rotation. The reset handle is fixed to the top of the swing arm, and the reset spring simultaneously abuts against the reset handle and the connecting plate. The sealing plate is fixed to the bottom of the swing arm and seals the material discharge opening.

[0010] Furthermore, a retaining ring is provided on the outer circumferential surface of the swing arm to limit the bearing position, and positioning flats are provided at both the upper and lower ends of the swing arm, with the reset handle and sealing plate fixed by screws.

[0011] Furthermore, the sealing plate is provided with a material discharge hole for discharging material and limiting rings on both sides. When the sealing plate rotates to face the material discharge hole, the coal sample begins to fall and be separated. When the sealing plate rotates to abut the limiting rings, the material discharge outlet channel is closed.

[0012] This utility model has the following beneficial technical effects:

[0013] By blocking and agitating the coal sample with the material blocking block and the sample dispensing rod, the coal sample can be directly separated, and the uniformity of the separated coal sample can be guaranteed. The opening and closing mechanism can restrict the coal sample separation process and control the weight of the separated sample. Moreover, the separation device can be moved as a whole, which ensures the convenience and reliability of cleaning and avoids sample residue. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Reference Figure 1 This embodiment includes a storage bin 1, a blocking block 2, a sampling rod 3, a distribution bin 4, and an opening and closing mechanism 5. The storage bin 1 and the distribution bin 4 are both hollow inside with openings at both ends and are fitted together by interlocking. The blocking block 2 and the sampling rod 3 are located inside the storage bin 1, and the opening and closing mechanism 5 is located on the left side of the distribution bin 4.

[0021] Reference Figure 1 and Figure 2 The storage bin 1 is divided into an inverted conical part and a cylindrical part. The bottom radius of the inverted conical part is the same as the radius of the cylindrical part, and the inverted conical part and the cylindrical part are integrally formed. The material blocking block 2 is located inside the cylindrical part. The outer circumferential surface of the cylindrical part has a positioning pin hole 11. By placing a positioning pin in the positioning pin hole 11, the material blocking block 2 is limited at the top and bottom, so that the movement of the material blocking block 2 and the control of coal powder falling are stable. In addition, the material blocking block 2 has a contact arc surface that matches the positioning pin.

[0022] Reference Figure 1 and Figure 2 The cylindrical parts of the material distribution bin 4 and the storage bin 1 are interlocked and fitted together by protrusions and grooves, and the material distribution bin 4 is generally inverted cone shape. The material distribution bin 4 has a discharge cone part 41 and a discharge opening 42, and a connecting plate 43 is provided on the side for fixing the opening and closing mechanism 5. The discharge cone part 41 is the cone-shaped part of the material distribution bin 4, and the discharge opening 42 is located at the bottom of the discharge cone part 41.

[0023] Reference Figure 1 and Figure 2 The sampling rod 3 is installed inside the distribution bin 4 and the storage bin 1, and has a through hole at the axis of the blocking block 2. The sampling rod 3 passes through the blocking block 2 and reaches the material discharge opening 42 of the distribution bin 4. The top of the sampling rod 3 has a sampling slot 31, which facilitates the operation of the sampling rod 3 to realize the up and down movement of materials. The bottom of the sampling rod 3 is provided with stirring rake teeth 32. Multiple stirring rake teeth 32 are provided and are evenly distributed around the sampling rod 3. When the sampling rod 3 rises and falls sharply, the stirring rake teeth 32 drive the blocking block 2 to move up and down relative to the storage bin 1, realizing the initial sampling of coal. When the sampling rod 3 rises and falls slightly, the axially distributed stirring rake teeth 32 drive the coal sample to fall slightly, realizing the precise control of the coal sample.

[0024] Reference Figure 3The opening and closing mechanism 5 includes a reset handle 51, a reset spring 52, a swing arm 54, and a sealing plate 55. A through hole is provided on the connecting plate 43. The swing arm 54 is rotated by being fitted into the through hole through a bearing 53. The reset handle 51 is fixed to the top of the swing arm 54, and the reset spring 52 simultaneously abuts against the reset handle 51 and the connecting plate 43. The sealing plate 55 is fixed to the bottom of the swing arm 54 and seals the material discharge opening 42. The material discharge opening 42 is opened by compressing the reset spring 52, and the material discharge opening 42 is sealed by the action of the reset spring 52. A retaining ring 541 is provided on the outer circumference of the swing arm 54 to limit the bearing 53. The position of the retaining ring 541 is exactly the position where the sealing plate 55 can seal the material discharge opening 42 after the reset spring 52 is reset. Positioning flats 542 are provided at both the upper and lower ends of the swing arm 54. The reset handle 51 and the sealing plate 55 can be fixed by screws 551. In addition, the sealing plate 55 is provided with a material discharge hole 552 for discharging material and a limiting ring 553 on both sides. When the sealing plate 55 rotates to face the material discharge hole 552, the coal sample begins to fall and be separated. When the sealing plate 55 rotates to abut the limiting ring 553, the material discharge outlet channel is closed.

[0025] The implementation principle of the micro-coal sample dispensing hopper in this embodiment of the utility model is as follows:

[0026] During sample separation, when the sample-dispensing rod 3 moves up and down significantly, the stirring rake teeth 32 cause the material blocking block 2 to move up and down relative to the storage bin 1, achieving initial sample feeding of the coal. When the sample-dispensing rod 3 moves up and down slightly, the axially distributed stirring rake teeth 32 cause the coal sample to fall slightly, achieving precise control of the coal sample. When the coal sample comes out of the discharge opening, the sealing plate 55 rotates to face the discharge hole 552, and the coal sample begins to fall and separate. When the sealing plate 55 rotates to abut the limiting ring 553, the discharge outlet channel is closed.
