Description

Technical Field

[0001] This utility model relates to the field of coal gangue crushing technology, and in particular to a novel multi-stage coal gangue crushing device. Background Technology

[0002] Coal gangue is a solid waste discharged during coal mining and washing. It is a blackish-gray rock with low carbon content and harder than coal that is associated with coal seams during coal formation. It includes gangue from tunnel excavation, gangue extracted from the roof, floor and interlayers during mining, and gangue from coal washing. Through specific processing techniques, coal gangue can be transformed into fertile black soil for agricultural production or ecological restoration.

[0003] Existing equipment for multi-stage crushing and screening is limited, and the structural design of the recovery device for collecting usable coal gangue particles does not consider the continuity with subsequent processes. Existing patent CN213529034U discloses a multi-stage crushing, screening, and recovery device for coal gangue, addressing the issues of limited existing multi-stage crushing and screening equipment and the lack of continuity with subsequent processes in the structural design of the recovery device. However, in practical use, after the initial screening of coal gangue, the existing technology cannot control the initial crushing size according to the size of the coal gangue and the crushing requirements, reducing the applicability of the crushing device to coal gangue. Therefore, further improvements are needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a new type of multi-stage crushing device for coal gangue.

[0005] This utility model is achieved through the following technical solution:

[0006] A novel multi-stage crushing device for coal gangue includes an outer shell. A feeding hopper is fixedly connected to the top of the outer shell. Two baffles are fixedly connected to the inner wall of the outer shell and symmetrically arranged at the bottom of the feeding hopper. An adjusting crushing mechanism is provided on the outer side of the outer shell. The adjusting crushing mechanism includes two bases. One side of each base is fixedly connected to the outer side of the outer shell. The two bases are symmetrically arranged on the outer side of the outer shell. Two first positioning seats are slidably connected to the top of one base. A drive motor is fixedly connected inside the first positioning seat. A rotating shaft is fixedly connected to the output end of the drive motor. A first crushing roller is fixedly connected to the outer side of the rotating shaft. A partition is rotatably connected to the outer side of the rotating shaft. The outer side of the partition is slidably connected to the inner wall of the outer shell. A slot is formed on the surface of the other base. Two second positioning seats are slidably connected to the top of the other base. Two pins are inserted into the bottom of each of the first and second positioning seats. The pins are inserted into the outer side of the base. The interior of each second positioning seat is rotatably connected to the rotating shaft. A protective shell is fixedly connected to one side of each second positioning seat. A locking block is slidably connected inside the protective shell. The bottom of the locking block engages with the slot.

[0007] As can be seen, in the above technical solution, the distance between the two first crushing rollers can be adjusted, which facilitates the crushing of coal gangue according to the required size.

[0008] Optionally, in one possible implementation, a screening and crushing mechanism is provided on one side of the outer casing. This mechanism includes a servo motor, one side of which is fixedly connected to the outer side of the outer casing. A drive cam is fixedly connected to the output end of the servo motor, and a screen plate is slidably connected to the top of the drive cam. Multiple fixed blocks are fixedly connected to the inner wall of the outer casing, and telescopic columns are fixedly connected to the tops of the fixed blocks. Springs are sleeved on the outer sides of the telescopic columns. A partition is fixedly connected to the inner wall of the outer casing, one side of the screen plate is hinged to the top of the partition, and the top of the telescopic column is fixedly connected to the lower surface of the screen plate. It can be seen that the above technical solution can perform a certain degree of screening between crushed small and large pieces of coal gangue.

[0009] Optionally, in one possible implementation, a dual-axis motor is fixedly connected to the outer side of the outer casing, and a second crushing roller is fixedly connected to each of the two output ends of the dual-axis motor. The outer side of the second crushing roller is rotatably connected to the inner wall of the outer casing. It can be seen that the above technical solution further crushes larger, less easily crushed coal gangue.

[0010] Optionally, in one possible implementation, a first collection box is slidably connected to the bottom of the outer casing, and a second collection box is slidably connected to the bottom of the outer casing, with the second collection box disposed on one side of the first collection box. It can be seen that the above technical solution involves the classified collection of crushed coal gangue.

[0011] The beneficial effects of this utility model are:

[0012] By setting an adjustable crushing mechanism, this utility model, compared with the prior art, can adjust the two first crushing rollers according to the required size of coal gangue, so that most of the coal gangue can be crushed into a more suitable size during crushing, thereby improving the crushing efficiency of coal gangue.

[0013] At the same time, by setting up a screening and crushing mechanism, compared with the existing technology, some of the larger and smaller coal gangue that are not easy to crush are screened, and then the larger and less easy-to-crush coal gangue is further crushed, so that the crushing of coal gangue is more comprehensive.

Two second positioning seats are slidably connected to the top of the base 4. The base 11, the first positioning seat 5 and the second positioning seat 11 are each fitted with two pins 12 at the bottom. The pins 12 are inserted into the outside of the base 4. The inside of the second positioning seat 11 is rotatably connected to the rotating shaft 7. A protective shell 13 is fixedly connected to one side of the second positioning seat 11. A locking block 14 is slidably connected inside the protective shell 13. The bottom of the locking block 14 is engaged with the locking groove 10. Pulling out multiple pins 12 can push the two drive motors 6 and the second positioning seat 11 to drive the rotating shaft 7 and the first crushing roller 8 to move in opposite directions inside the outer shell 1. At the same time, the protective shells 13 and the locking blocks 14 on the outside of the two second positioning seats 11 can engage with the locking groove 10 on the top of the base 4, so that the two first crushing rollers 8 can be positioned and fixed during the movement. Then the two drive motors 6 drive the rotating shaft 7 and the first crushing roller 8 to crush the coal gangue.

[0027] Example 2:

[0028] A screening and crushing mechanism is provided on one side of the outer casing 1. The screening and crushing mechanism includes a servo motor 15. One side of the servo motor 15 is fixedly connected to the outside of the outer casing 1. A drive cam 16 is fixedly connected to the output end of the servo motor 15. A screen plate 17 is slidably connected to the top of the drive cam 16. Multiple fixing blocks 18 are fixedly connected to the inner wall of the outer casing 1. A telescopic column 19 is fixedly connected to the top of the fixing block 18. A spring 20 is sleeved on the outside of the telescopic column 19. A partition plate 21 is fixedly connected to the inner wall of the outer casing 1. One side of the screen plate 17 is hinged to the top of the partition plate 21. The top of the telescopic column 19 is fixedly connected to the lower surface of the screen plate 17. A dual-shaft motor 22 is fixedly connected to the outside of the outer casing 1. A second crushing roller 23 is fixedly connected to both output ends of the dual-shaft motor 22. The outer side of the crushing roller 23 is rotatably connected to the inner wall of the outer casing 1. The bottom of the outer casing 1 is slidably connected to the first collection box 24 and the bottom of the outer casing 1 is slidably connected to the second collection box 25. The second collection box 25 is located on one side of the first collection box 24. The servo motor 15 drives the drive cam 16 to vibrate the screen plate 17 up and down. At the same time, during the up and down vibration of the screen plate 17, the screen plate 17 is supported by multiple telescopic columns 19 and springs 20 at the bottom, so that the screen plate 17 can vibrate the coal gangue up and down, thereby speeding up the screening. Then, the dual-shaft motor 22 drives the two second crushing rollers 23 to further crush the larger coal gangue. The crushed coal gangue is then classified and collected by the first collection box 24 and the second collection box 25.

[0029] Working principle of this utility model: This utility model designs a novel multi-stage crushing device for coal gangue, the specific structure of which is shown in the attached instruction manual. Figure 1-7As shown, in this technical solution, through the cooperation between various structures, before crushing the coal gangue, the pins 12 on the outer sides of the two bases 4 are pulled out according to the required size of the coal gangue blocks to be crushed. Then, the two first positioning seats 5 and the second positioning seats 11 are pushed to slide inside the two bases 4. During the sliding process of the two second positioning seats 11, the spring inside the protective shell 13 on one side of the second positioning seat 11 will push the locking block 14 to engage with the corresponding locking groove 10 on the top of the base 4, so that the movement distance of the two rotating shafts 7 and the first crushing roller 8 can be quickly positioned, making it easy to reinsert the pins 12 into the two bases 4 and the corresponding first positioning seats 5 and second positioning seats 11 to fix the position of the two first crushing rollers 8. At the same time, the two first crushing rollers 8 will maintain a distance from each other and will not contact each other. Then, the coal gangue is fed into the interior of the outer shell 1 from the feeding funnel 2. Guided by the baffle 3, the coal gangue is... The coal gangue falls between the two first crushing rollers 8. Then, the two drive motors 6 drive the corresponding rotating shafts 7 and the first crushing rollers 8 to rotate in opposite directions, crushing the coal gangue. The crushed coal gangue then falls onto the top of the screen plate 17. At the same time, the servo motor 15 drives the drive cam 16 to vibrate the screen plate 17 up and down slightly. During the up and down movement of the screen plate 17, the vibration of the screen plate 17 is made faster and more stable with the assistance of multiple telescopic columns 19 and springs 20, allowing the coal gangue to move to one side on the inclined top of the screen plate 17. During the movement of the coal gangue, smaller coal gangue falls through the screen plate 17 into the interior of the first collection box 24, while larger coal gangue moves to the top of the two second crushing rollers 23 through the vibration of the screen plate 17. Then, the dual-shaft motor 22 drives the two second crushing rollers 23 to further crush the larger coal gangue, so that the crushed coal gangue enters the interior of the second collection box 25 for collection.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
