[0032] As Figure 1 , Figure 5 , Figure 6 , Figure 7 ,Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the crushing mechanism includes a crushing roller 15, a crushing box 16, a first jaw plate 17, a translation mechanism, a second jaw plate 25, and a screen plate 27. The crushing box 16 is fixedly connected to the top of the feeding frame 4. The crushing box 16 has a feed inlet at the top and communicates with the feeding frame 4. The crushing roller 15 is rotatably connected inside the crushing box 16. The first jaw plate 17 is slidably connected inside the crushing box 16. The second jaw plate 25 is fixedly connected inside the crushing box 16. The screen plate 27 is installed inside the crushing box 16. The connecting shaft 81 passes through the crushing box 16. The crushing roller 15 is fixedly connected to the crushing roller 15, which is located between the first jaw plate 17 and the second jaw plate 25. The distance between the first jaw plate 17 and the crushing roller 15 is smaller than the distance between the second jaw plate 25 and the crushing roller 15. The screen plate 27 is located below the crushing roller 15. The half of the screen plate 27 near the second jaw plate 25 is without holes, while the half of the screen plate 27 near the first jaw plate has screen holes. During normal crushing operation, the second jaw plate 25 blocks the half of the screen plate 27 without holes, and the processed raw material falls normally from the half with screen holes. A translation mechanism is connected to the second jaw plate 25.

[0033] like Figures 5-8 As shown, the translation mechanism includes a third motor 18, a first gear 19, a second gear 20, a screw 21, a threaded plate 22, a clamping plate 221, a sliding rod 23, a second elastic element 24, a sliding plate 251, a clamping block 2510, and a stop block 26. The third motor 18 is installed inside the slag box 16. The first gear 19 is fixedly connected to the output shaft of the third motor 18. The screw 21 is rotatably connected inside the slag box 16. The second gear 20 is fixedly connected to the screw 21. A threaded plate 22 is threadedly connected to the screw 21. A gap is left between the threaded plate 22 and the second jaw plate 25. The first gear 19 meshes with the second gear 20. The bottom of the threaded plate 22 is fixed. A clamping plate 221 is connected, and the front and rear sides of the clamping plate 221 are annular. The front and rear sides of the threaded plate 22 are slidably connected to sliding rods 23. The sliding rods 23 are fixedly connected to the second jaw plate 25. The sliding rods 23 and the threaded plate 22 are fixedly connected to the second elastic element 24. The bottom of the slag box 16 is slidably connected to a sliding plate 251. The front and rear sides of the top of the sliding plate 251 are fixedly connected to clamping blocks 2510. The front and rear clamping blocks 2510 are both located in the annular groove of the clamping plate 221. There is a gap between the front and rear clamping blocks 2510 and the front side of the annular groove. The front and rear sides of the inside of the slag box 16 are fixedly connected to baffles 26. The baffles 26 are both located above the screen plate 27.

[0034] When the slagging mechanism is used for slagging, the unprocessed raw materials are poured into the slagging box 16, and the unprocessed raw materials are located between the second jaw plate 25 and the slagging roller 15. Then, the first motor 5 drives the connecting shaft 81 to rotate, thereby driving the slagging roller 15 to rotate. When the slagging roller 15 rotates, the unprocessed raw materials are extruded and broken, and then fall on the sieve plate 27. Then, the unprocessed raw materials fall in the discharging frame 4 through the sieve holes on the sieve plate 27. The processed raw materials with an outer diameter greater than the outer diameter of the sieve holes on the sieve plate 27 are driven by the slagging roller 15 to the first jaw plate 17 for secondary extrusion and breaking, so as to ensure that the processed raw materials can be completely broken and pass through the sieve holes. In the slagging process, under the extrusion action of the second jaw plate 25, the second elastic member 24 is compressed, so as to make the second jaw plate 25 move away from the slagging roller 15, thereby ensuring normal slagging when encountering large unprocessed raw materials, preventing large unprocessed raw materials from being retained between the slagging roller 15 and the second jaw plate 25 to cause blockage, and restoring the second jaw plate 25 to the original position after the slagging of large unprocessed raw materials is completed. The adaptability of the blockage control system is enhanced. When it is necessary to slag large raw materials, the third motor 18 drives the first gear 19 to rotate. Under the meshing action of the first gear 19 and the second gear 20, the first gear 19 drives the second gear 20 to rotate, so that the screw rod 21 rotates and drives the threaded plate 22 to slide along the sliding rod 23 away from the slagging roller 15. The threaded plate 22 drives the sliding rod 23 to move away from the slagging roller 15, the second elastic member 24 is stretched, the gap between the front and rear clamping blocks 2510 and the front side of the annular groove is shortened, so that the second jaw plate 25 slides away from the slagging roller 15. Thus, the distance between the second jaw plate 25 and the slagging roller 15 can be increased, the distance between the second jaw plate 25 and the slagging roller 15 is adjusted to adapt to the slagging of raw materials of different sizes, and the blocked unprocessed raw materials can fall out of the second jaw plate 25 and the slagging roller 15, so as to solve the problem that the unprocessed raw materials are blocked between the second jaw plate 25 and the slagging roller 15. After the blocking of the unprocessed raw materials is solved, the second jaw plate 25 can be reset by reversing the third motor 18. The stop block 26 can limit the reset distance of the second jaw plate 25, prevent the distance between the second jaw plate 25 and the slagging roller 15 from being too close to cause the unprocessed raw materials to be blocked during slagging, and make the distance between the second jaw plate 25 and the slagging roller 15 appropriate to facilitate the slagging of the unprocessed raw materials.

[0035] As Figure 1 , Figure 5 , Figure 8 and Figure 9As shown, it also includes slide column 270, guide plate 28, material blocking plate 403 and partition plate 29, slide column 270 is connected on screen plate 27, through slot 404 is opened on blanking frame 4, guide plate 28 is slidably connected in through slot 404, guide plate 28 is fixedly connected with sliding plate 251, inclined guide slot 280 is opened on guide plate 28, left side of guide slot 280 is higher than right side, slide column 270 is slidably connected in guide slot 280, material blocking plate 403 and partition plate 29 are fixedly connected inside blanking frame 4, coarse material port 401 is opened on bottom of blanking frame 4 near non-hole half of screen plate 27, fine material port 402 is opened on bottom of blanking frame 4 near screen hole half of screen plate 27.

[0036] When the gap between the two front and rear clamping blocks 2510 and the front side in the annular groove is continuously shortened, the clamping plate 221 will contact and extrude the clamping block 2510, so that the sliding plate 251 drives the front and rear guide plates 28 away from the slag roller 15, so that the slide column 270 slides along the guide slot 280, the slide column 270 drives the screen plate 27 to rotate downward, so that the blocked unprocessed raw materials slide from the left side of the screen plate 27 into the coarse material port 401 of the blanking frame 4, and the processed raw materials that can pass through the screen hole fall into the fine material port 402, thereby eliminating the need for manual removal of blocked unprocessed raw materials, and achieving classification processing of processed raw materials and unprocessed raw materials, facilitating subsequent re-crushing of unprocessed raw materials. The partition plate 29 can prevent unprocessed raw materials from falling into the fine material port 402 and mixing with processed raw materials, and the material blocking plate 403 can prevent unprocessed raw materials from remaining in the blanking frame 4. When the second jaw plate 25 is reset, the clamping plate 221 extrudes the clamping block 2510, so that the sliding plate 251 drives the front and rear guide plates 28 to approach the slag roller 15, and the slide column 270 reversely slides along the guide slot 280, so that the screen plate 27 reversely rotates and resets, thereby speeding up the recovery of the crushing mechanism and greatly reducing the downtime caused by blockage.

[0037] As shown in Figure 1 , Figure 10 and Figure 11 , it also includes feeding frame 30 and inclined plate 31, feeding frame 30 is fixedly connected on top of slag box 16, feeding frame 30 communicates with the feed inlet of slag box 16, inclined plate 31 is fixedly connected inside feeding frame 30, left side of inclined plate 31 is lower than right side. When it is necessary to add unprocessed raw materials in the crushing mechanism, the unprocessed raw materials are poured into the feeding frame 30, and then fall on the inclined plate 31 and between the second jaw plate 25 and the slag roller 15. Since the distance between the first jaw plate 17 and the slag roller 15 is small, when the unprocessed raw materials fall between the first jaw plate 17 and the slag roller 15, it is easy to cause blockage. The inclined plate 31 can prevent the unprocessed raw materials from falling between the first jaw plate 17 and the slag roller 15 to cause blockage.

[0038] As shown in Figure 1 ,Figure 10 and Figure 11 As shown in FIG. 16, the slag box 16 further comprises a sliding block 32, a sliding column 33, a material blocking plate 34, a rubber plate 35 and a limiting plate 36. The slag box 16 is provided with a sliding groove 160, and the sliding block 32 is slidably connected in the sliding groove 160. The sliding block 32 penetrates through the outer wall of the feeding frame 30. The top of the sliding block 32 is provided with an inclined surface. The feeding frame 30 is rotatably connected with the sliding column 33 on the side close to the sliding block 32. The rotating connection between the sliding column 33 and the feeding frame 30 is provided with a strong torsion spring. The sliding column 33 is slidably connected on the inclined surface of the top of the sliding block 32. The side of the sliding column 33 away from the sliding block 32 is fixedly connected with the material blocking plate 34. The left side of the material blocking plate 34 is higher than the right side. The material blocking plate 34 is located inside the feeding frame 30. The material blocking plate 34 and the feeding frame 30 are fixedly connected with the rubber plate 35. The rubber plate 35 can prevent the unprocessed raw materials from falling into the rotating connection between the sliding column 33 and the feeding frame 30 to cause mechanical jam. The rubber plate 35 made of rubber does not affect the rotation of the sliding column 33. The part of the sliding block 32 penetrating through the feeding frame 30 is fixedly connected with the limiting plate 36. The limiting plate 36 is located below the material blocking plate 34.

[0039] When the unprocessed raw materials are poured into the feeding frame 30, the unprocessed raw materials fall on the material blocking plate 34 and then fall on the inclined plate 31. The strong torsion spring can support the sliding column 33 to prevent the material blocking plate 34 from rotating downward and contacting the inclined plate 31 under the action of gravity, thereby ensuring the normal feeding of the unprocessed raw materials. When the material blocking plate 34 is blocked, the second jaw plate 25 slides away from the slag roller 15, so that the sliding block 32 slides away from the feeding frame 30 along the sliding groove 160. The sliding column 33 rotates upward along the inclined surface of the top of the sliding block 32, so that the material blocking plate 34 rotates downward and contacts the inclined plate 31, thereby blocking the feeding frame 30 to prevent the subsequent unprocessed raw materials from continuing to fall into the slag box 16 and hindering the recovery of the slag mechanism. When the second jaw plate 25 is reset, the sliding block 32 moves back along the sliding groove 160. The sliding column 33 reversely rotates downward along the inclined surface of the top of the sliding block 32. The material blocking plate 34 reversely rotates away from the inclined plate 31, so that the unprocessed raw materials can continue to fall into the slag mechanism for slag treatment. When the unprocessed raw materials on the material blocking plate 34 are heavy, the material blocking plate 34 will rotate. The limiting plate 36 can prevent the material blocking plate 34 from rotating excessively and contacting the inclined plate 31 to cause the unprocessed raw materials to be blocked in the feeding frame 30, thereby ensuring the normal feeding of the unprocessed raw materials.

[0040] The above description is only the preferred embodiment of the present application. It should be pointed out that those skilled in the art can make some improvements and refinements without departing from the principles of the present application. These improvements and refinements should also be considered as the protection scope of the present application.
