[0001] This utility model relates to the field of coal quality sampling and sorting technology, and more specifically to a coal quality sampling and sorting device. Background Technology

[0002] Coal sampling refers to collecting a small, representative sample from a large quantity of coal for subsequent quality analysis and testing. When collecting coal samples, a sorting device is typically used to separate coal particles of different sizes. This device usually works by vibrating the coal through a screen. Currently, the screens are typically fixed, which means the sorting device can only separate coal particles within a fixed size range. This prevents the device from effectively changing the screen to accommodate the different particle sizes required for production, and also makes it inconvenient for staff to collect samples from different size ranges. This process needs improvement. Summary of the Invention

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Furthermore, the structural forms described in the following embodiments are merely illustrative. The coal sampling and sorting device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Examples

[0025] As shown in Figures 1-9, a coal quality sampling and sorting device includes a sorting box 1. The sorting box 1 is equipped with a sorting mechanism 2 inside. The sorting mechanism 2 includes two screening screens 21. The two screening screens 21 are symmetrically and movably fitted inside the sorting box 1. Two limiting grooves 216 are opened on the front of the sorting box 1. Limiting strips 211 are fixedly connected to the front of the screening screens 21. The outer wall of the limiting strips 211 is movably fitted inside the limiting grooves 216. A handle 212 is fixedly connected to the front of the limiting strips 211. No. 1 bolts 213 are threadedly connected to both sides of the front of the limiting strips 211. One end of the No. 1 bolt 213 is threadedly connected inside the limiting grooves 216. Multiple positioning blocks 214 are fixedly connected to the back of the two screening screens 21. Multiple positioning grooves 215 are opened at the rear of the inner wall of the sorting box 1. The outer wall of the positioning blocks 214 is inserted into the positioning grooves 215.

[0026] In this embodiment, the first bolt 213 on the limiting strip 211 is removed by screwing it off. Then, the operator moves the limiting strip 211 using the handle 212. The limiting strip 211 causes the screening screen 21 to move out of the sorting box 1 through the limiting groove 216, facilitating the disassembly of the screening screen 21. When installing the screening screen 21, the rear end of the screening screen 21 is inserted into the sorting box 1 through the limiting groove 216, and the positioning block 214 on the back of the screening screen 21 is inserted into the positioning groove 215, thus initially limiting the screening screen 21. Then, one end of the first bolt 213 is installed inside the limiting groove 216 through the limiting strip 211, thus fixing the limiting strip 211 and the screening screen 21. This allows for the replacement of screening screens 21 with different apertures, facilitating the sampling and collection of coal with different particle size ranges. Example

[0027] As shown in Figures 1-9, a base 3 is provided below the sorting box 1. A motor 22 is fixedly installed on the top of the base 3. A connecting shaft 23 is fixedly connected to the output end of the motor 22. An eccentric block 24 is fixedly installed on the outer wall of the connecting shaft 23. The eccentric block 24 is located in the middle of the bottom of the sorting box 1. A support plate 25 is fixedly installed behind the top of the base 3. The rear end of the connecting shaft 23 is rotatably mounted on the front of the support plate 25 through a bearing. Mounting grooves 26 are provided around the top of the base 3. A slider 28 is slidably connected to one side of the mounting groove 26. A connecting frame is hinged around the bottom of the sorting box 1. 27. The bottom end of the connecting frame 27 is hinged to the top of the slider 28. A straight rod 29 is fixedly connected inside the mounting groove 26. The slider 28 is slidably sleeved on the outer wall of the straight rod 29. A spring 291 is movably sleeved on the outer wall of the straight rod 29. One end of the spring 291 is fixedly connected to one side of the slider 28, and the other end of the spring 291 is fixedly connected to the other side of the inner wall of the mounting groove 26. Four guide telescopic rods 292 are fixedly installed at the four corners of the top of the base 3. The telescopic ends of the four guide telescopic rods 292 are fixedly installed at the four corners of the bottom of the sorting box 1.

[0028] In this embodiment, the screen aperture of the upper screening screen 21 inside the sorting box 1 is larger than that of the lower screening screen 21, which facilitates multi-stage screening of the coal. The sorting box 1 can be made of high-strength wear-resistant alloy steel, which has good wear resistance and impact resistance, and can withstand the impact and wear generated by the movement of the eccentric block 24. Through the cooperation of the motor 22 and the connecting shaft 23, it is easy to drive the eccentric block 24 to rotate. The eccentric block 24 impacts the bottom of the sorting box 1, causing the sorting box 1 to vibrate and move vertically up and down. The upward movement of the sorting box 1 will drive the extension end of the guide telescopic rod 292 and the top end of the connecting frame 27 to move. The guide telescopic rod 292 facilitates the vertical guidance of the sorting box 1. While moving, its bottom end can drive the slider 28 to slide inside the mounting groove 26 and on the outer wall of the straight rod 29. The slider 28 compresses the spring 291. At this time, one end of the spring 291 is compressed. When the eccentric block 24 disengages from the bottom of the sorting box 1, the sorting box 1 moves downward to reset itself by its own weight and the elasticity of the spring 291. This allows the eccentric block 24 to strike the sorting box 1, causing the two screening screens 21 inside the sorting box 1 to move up and down and vibrate. The upper screening screen 21 is used to perform preliminary screening of the coal. Coal with a smaller aperture than the upper screening screen 21 falls onto the lower screening screen 21 for screening, while coal with a smaller aperture than the lower screening screen 21 falls into the bottom of the inner cavity of the sorting box 1, making it easier to screen the coal. Example

[0029] As shown in Figure 1-9, three baffles 43 are movably fitted on the right side inside the sorting box 1. Two baffles 43 are located above the right side of the two screening screens 21, and the other baffle 43 is located below the right side inside the sorting box 1. Three electric telescopic rods 4 are fixedly installed on the right side of the sorting box 1. The telescopic ends of the three electric telescopic rods 4 extend into the interior of the sorting box 1 and are fixedly connected to the middle of one side of the three pusher plates 41. Three discharge ports 42 are opened on the left side of the sorting box 1, two of which are located at the two... Above the left side of the screening screen 21, another discharge port 42 is located below the left side of the sorting box 1. Each of the three discharge ports 42 has a baffle 43 that is movably inserted inside. A handle 431 is fixedly connected to the front end of the baffle 43. A No. 2 bolt 432 is threadedly connected to the front end of the inside of the baffle 43. One end of the No. 2 bolt 432 is threadedly connected to the front end inside the discharge port 42. Three inclined discharge covers 44 are fixedly installed on the left side of the sorting box 1. The three inclined discharge covers 44 are located below the left side of the three discharge ports 42.

[0030] In this embodiment, the No. 2 bolt 432 facilitates the fixed installation of the baffle 43 inside the discharge port 42, preventing coal from being discharged from the discharge port 42 during sorting. When collecting the sorted coal, the No. 2 bolt 432 on the three baffles 43 is removed, and the baffles 43 are pulled out from the discharge port 42 through the handle 431. At this time, the discharge port 42 is opened, and the three push plates 41 are moved by the three electric telescopic rods 4. The three push plates 41 push the coal at the bottom of the two screening screens 21 and the inner cavity of the sorting box 1 to move and be discharged through the discharge port 42 and the inclined discharge cover 44, making it convenient to discharge the screened coal from the inside of the sorting box 1.

[0031] In summary, as shown in Figures 1-9, this coal sampling and sorting device, when in use, places the coal inside the sorting box 1. The output of the motor 22 drives the connecting shaft 23 and the eccentric block 24 to rotate. The eccentric block 24 impacts the bottom of the sorting box 1, causing it to vibrate and move vertically up and down. The upward movement of the sorting box 1 simultaneously moves the telescopic end of the guide rod 292 and the top of the connecting frame 27. The bottom of the connecting frame 27 also drives the slider 28 to slide inside the mounting groove 26 and on the outer wall of the straight rod 29. Simultaneously, the slider 28 compresses the spring 291, compressing one end. When the eccentric block 24 disengages from the bottom of the sorting box 1, the sorting box 1 returns to its original position by moving downwards under its own weight and the elasticity of the spring 291. This process, using the impact of the eccentric block 24, causes the sorting box 1 to vibrate and move vertically up and down. It can drive the two screening screens 21 inside to move up and down and generate vibration. The upper screening screen 21 is used to perform preliminary screening of coal. Coal with a diameter smaller than the upper screening screen 21 falls onto the lower screening screen 21 for screening. Coal with a diameter smaller than the lower screening screen 21 falls into the bottom of the inner cavity of the sorting box 1, which facilitates the screening of coal. After screening, the staff first removes the No. 2 bolts 432 on the three baffles 43 and pulls the baffles 43 out from the inside of the discharge port 42 through the handle 431. At this time, the discharge port 42 is opened, and then the three push plates 41 are pushed to move by the three electric telescopic rods 4. The three push plates 41 push the two screening screens 21 and the coal at the bottom of the inner cavity of the sorting box 1 to move and discharge through the discharge port 42 and the inclined discharge hood 44, which makes it convenient to discharge the screened coal from the inside of the sorting box 1.
