[0027] 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.

[0028] Please see Figure 1-7 This utility model provides a technical solution: a crushing device, including a storage mechanism 2 for storing coal raw materials and a crushing mechanism 3 disposed inside the storage mechanism 2 for crushing the coal raw materials, and further including:

[0029] The filter screen 24 is installed inside the storage mechanism 2 and below the crushing mechanism 3, and is used to filter the coal raw material.

[0030] The cleaning mechanism 4 is installed on the storage mechanism 2 and located below the filter screen 24, and is used to clean the filter screen 24.

[0031] Cleanup organization 4 includes:

[0032] The pusher is mounted on storage mechanism 2;

[0033] The cleaning brush 44 is mounted on the pusher and located below the filter screen 24, and is used to clean impurities in the filter screen 24.

[0034] It should be noted that during operation, coal blocks are added into the storage mechanism 2, and then the crushing mechanism 3 is opened to crush the coal blocks inside the storage mechanism 2. Qualified coal powder falls from the filter screen 24 and is discharged from the storage mechanism 2. The crushed coal powder can be conveyed by the conveying mechanism at the lower end of the storage mechanism 2. After the crushing device has been used for a period of time, the crushing mechanism 3 is closed and the coal powder inside the storage mechanism 2 is discharged. At this time, the operator pushes the pusher to move the cleaning brush 44 below the filter screen 24. The cleaning brush 44 then extends into the mesh of the filter screen 24. During the movement, it cleans the impurities remaining in the filter screen 24, maintains the cleanliness of the filter screen 24, and improves the filtration efficiency of the filter screen 24 for coal. The filter screen 24 can filter the coal raw material to ensure that only qualified particles pass through, thereby improving the uniformity and efficiency of crushing.

[0035] In one embodiment, the storage mechanism 2 includes a crushing box 22, a guide bin 21 fixed to the upper end of the crushing box 22, and a feeding frame 23 disposed at the lower end of the crushing box 22. The crushing mechanism 3 is disposed inside the crushing box 22.

[0036] This design is for reference. Figure 1-3 ,as well as Figure 6 The coal blocks are conveyed to the inside of the feed hopper 21 by the conveying mechanism, and then fall into the inside of the crushing box 22. Then the crushing mechanism 3 is turned on to crush the coal blocks inside the crushing box 22. The coal powder with qualified particle size falls from the filter screen 24 into the feeding frame 23. The feeding frame 23 is set at the lower end of the crushing box 22 to collect the crushed coal particles for subsequent transportation and processing.

[0037] In one embodiment, a fixed frame 1 is fixed to the lower end of the crushing box 22. The pushing component includes a pushing handle 41, a cleaning shaft 42 disposed on the pushing handle 41 and passing through the feeding frame 23, and a cleaning roller 43 fixed at the position of the cleaning shaft 42 inside the feeding frame 23. Cleaning brushes 44 are fixed at intervals on the cleaning roller 43. An adjustment groove 2301 for the cleaning shaft 42 to move is provided on the feeding frame 23.

[0038] This design is for reference. Figure 4-6 When the filter screen 24 needs to be cleaned, push the handle 41 to move the cleaning shaft 42 inside the adjustment groove 2301. Then, the cleaning brush 44 moves below the filter screen 24 to clean the impurities accumulated in the filter screen 24. It can effectively remove the stubborn impurities attached to the mesh of the filter screen 24 and ensure the cleanliness of the filter screen 24. The opening of the adjustment groove 2301 provides space for the movement of the cleaning shaft 42, so that the cleaning mechanism 4 can flexibly adjust its position according to actual needs and adapt to different cleaning requirements.

[0039] In one embodiment, a square limiting block 411 is provided at the position where the push handle 41 is connected to the fixed frame 1, and a moving groove 101 is provided on the fixed frame 1 for the limiting block 411 to move.

[0040] This design is for reference. Figure 5 The cooperation between the limiting block 411 and the moving groove 101 provides a stable guiding effect for the push handle 41. During the cleaning process, when the operator pushes the push handle 41, the limiting block 411 will move along the moving groove 101, ensuring that the movement path of the cleaning mechanism 4 is straight and stable, avoiding deviation or shaking.

[0041] In one embodiment, a transmission component 45 is provided on the unloading frame 23. The transmission component 45 includes a rack 451 fixed on the outside of the unloading frame 23 and an adjusting gear 452 sleeved on the cleaning shaft 42. The adjusting gear 452 is meshed with the rack 451.

[0042] This design is for reference. Figure 4 ,as well as Figure 5 By meshing the rack 451 with the adjusting gear 452, the cleaning shaft 42 is rotated during movement, which further improves the cleaning efficiency of the cleaning brush 44 on the filter screen 24.

[0043] In one embodiment, the crushing mechanism 3 includes a motor 31 fixed on the fixed frame 1, a rotating shaft 32 fixed to the power output end of the motor 31 and passing through the feeding frame 23, a drive gear 33 sleeved on the rotating shaft 32, a crushing shaft 35 passing through the feeding frame 23, and a driven gear 34 sleeved on the crushing shaft 35 and meshing with the drive gear 33. Crushing blades 36 are provided on the crushing shaft 35 and the rotating shaft 32. The crushing blades 36 are located inside the crushing box 22. The crushing box 22 is provided with a protective box 25 for protecting the drive gear 33 and the driven gear 34.

[0044] This design is for reference. Figure 1-3 ,as well as Figure 7 The motor 31 serves as the power source, driving the drive gear 33 to rotate via the rotating shaft 32, which in turn drives the driven gear 34 and the crushing shaft 35 to rotate, enabling the crushing blades 36 to rotate at a high speed and achieve efficient crushing of coal raw materials. The crushing blades 36 on the rotating shaft 32 and the crushing shaft 35 are staggered, which can fully crush the coal blocks inside the crushing box 22. The crushing blades 36 will cut and impact the coal raw materials evenly, resulting in uniform particle size after crushing, thus improving the quality and consistency of the product.
