[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0023] Example:
[0024] like Figures 1-4 As shown, a fuel pellet screening device includes a screening machine body 1, with discharge ports 2 at both ends of the screening machine body 1, an adjusting screening mechanism 3 movably disposed on the inner side of the screening machine body 1, a feeding mechanism 4 symmetrically disposed on the top of the screening machine body 1, a limiting bottom block 5 disposed on the bottom of the screening machine body 1, a movable insert plate 6 movably connected to the inner side of the limiting bottom block 5, a first handle 7 fixedly connected to the front surface of the movable insert plate 6, a movable collection mechanism 8 placed at the bottom of the screening machine body 1, classification collection mechanisms 9 placed at both ends of the screening machine body 1, a fixed through groove 10 opened at the bottom of the screening machine body 1, inclined guide blocks symmetrically disposed on the inner bottom end of the screening machine body 1, and a vibration motor disposed on the rear surface of the screening machine body 1.
[0025] The working principle of the above technical solution is as follows:
[0026] During use, the inner side of the feeding mechanism 4 is first filled with raw materials. When the material needs to be collected by the classification and collection mechanism 9 on the right, the adjusting screening mechanism 3 is adjusted so that it can tilt to the right. Then, the feeding mechanism 4 located on the top left of the screening machine body 1 is adjusted so that the raw materials on the left are discharged downwards. At the same time, the movable insert plate 6 is pulled out from the inside of the limiting bottom block 5. Then, during the screening process, the screened raw materials can move and be collected inside the classification and collection mechanism 9 and the movable collection mechanism 8 on the right. When the classification and collection mechanism 9 on the right is almost full, Adjust the tilt direction of the screening mechanism 3 so that it tilts to the left. At this time, close the feeding mechanism 4 on the left and open the feeding mechanism 4 on the right, so that the classification and collection mechanism 9 on the left can collect the screened raw materials. At the same time, replace the classification and collection mechanism 9 on the right. When it is necessary to replace the movable collection mechanism 8, first insert the movable insert plate 6 into the inside of the limiting bottom block 5 to block the fixed through groove 10, and then replace the movable collection mechanism 8. After the replacement is completed, pull out the movable insert plate 6 again to collect the raw materials. The operation is convenient.
[0027] In another embodiment, such as Figure 2 As shown, the adjusting screening mechanism 3 includes movable mounting blocks 11 symmetrically located inside the screening machine body 1 and movably connected by connecting shafts. The top of the movable mounting blocks 11 is fixedly connected to a first screen 12 and a second screen 13 respectively. The bottom end of the first screen 12 is fixedly connected to a first connecting block 14. The top end of the second screen 13 is fixedly connected to a second connecting block 15. The inner sides of the first connecting block 14 and the second connecting block 15 are movably connected by connecting shafts to a movable connecting arm 16. The bottom end of the second screen 13 is fixedly connected to a third connecting block 17. The bottom inner side of the screening machine body 1 is fixedly connected to a fourth connecting block 19. The inner sides of the third connecting block 17 and the fourth connecting block 19 are movably connected by connecting shafts to a first mounting block 18 and a second mounting block 20 respectively. The ends of the first mounting block 18 and the second mounting block 20 are fixedly connected to each other. A first electric telescopic rod 21 is fixedly connected between the ends of the first mounting block 18 and the second mounting block 20.
[0028] When the first electric telescopic rod 21 retracts, it can drive the first mounting block 18 to move, thereby causing the third connecting block 17, the second screen 13, the second connecting block 15, the movable connecting arm 16, the first connecting block 14, and the first screen 12 to shift. This allows the movable mounting block 11 to deflect inside the screening machine body 1, the movable connecting arm 16 to deflect between the first connecting block 14 and the second connecting block 15, and the first mounting block 18 and the second mounting block 20 to deflect inside the third connecting block 17 and the fourth connecting block 19, thereby adjusting the tilt direction of the first screen 12 and the second screen 13.
[0029] In another embodiment, such as Figure 2 As shown, inclined guide blocks are provided at both ends of the inner bottom of the screening machine body 1.
[0030] When the raw material screened by the second screen 13 falls downwards, it can move towards the inside of the fixed channel 10 under the guidance of the inclined guide block, making operation convenient.
[0031] In another embodiment, such as Figure 3 As shown, the feeding mechanism 4 includes a fixed mounting rod 23. A connecting mounting plate 24 is fixedly connected to the top of the fixed mounting rod 23. Fixed support arms 25 are symmetrically arranged on the top of the connecting mounting plate 24. A feeding funnel 26 is fixedly connected to the inner side of the fixed support arm 25. A connecting bottom frame 27 is fixedly connected to the bottom of the feeding funnel 26. Fixed guide frames 28 are provided on both sides of the connecting bottom frame 27. Fixed slots 29 are opened inside the connecting bottom frame 27 and the fixed guide frames 28. Fixed sleeve blocks 30 are symmetrically arranged on the top of the connecting mounting plate 24. A second electric telescopic rod 31 is fixedly connected inside the fixed sleeve block 30. A fixed connecting arm 32 is fixedly connected to the output end of the second electric telescopic rod 31. A connecting end block 33 is fixedly connected to the lower part of the fixed connecting arm 32 near the second electric telescopic rod 31. A connecting sealing plate 34 is fixedly connected to the side of the connecting end block 33 near the second electric telescopic rod 31.
[0032] The second electric telescopic rod 31 can push and pull the fixed connecting arm 32, thereby moving the connecting end block 33 and the connecting sealing plate 34, and thus opening and closing the connecting bottom frame 27, which is convenient to operate.
[0033] In another embodiment, such as Figure 3 As shown, the outer surface of the connecting sealing plate 34 slides and fits against the inner side of the fixing slot 29 and the inner side of the fixing guide frame 28.
[0034] The sealing plate 34 can be stably moved inside the fixed slot 29 and the fixed guide frame 28, making operation convenient.
[0035] In another embodiment, such as Figure 2 As shown, the active collection mechanism 8 includes an active collection box 35, with a first universal wheel 36 symmetrically arranged at the bottom end of the active collection box 35, and a second handle 37 fixedly connected to one side of the active collection box 35.
[0036] When the second handle 37 is pulled, the movable collection box 35 can be quickly moved and replaced with the help of the first caster wheel 36, making operation convenient.
[0037] In another embodiment, such as Figure 4 As shown, the sorting and collection mechanism 9 includes a mounting base 38. The bottom end of the mounting base 38 is symmetrically provided with second universal wheels 39. The top of the mounting base 38 is fixedly connected to a first collection box 40. The top of the first collection box 40 is symmetrically provided with fixed connecting columns 41. The top of the fixed connecting columns 41 is fixedly connected to a second collection box 42. Both the first collection box 40 and the second collection box 42 have fixed discharge ports 43 on one side. Both the first collection box 40 and the second collection box 42 have guide blocks 44 on one side. The inner side of the guide block 44 near the end of the second collection box 42 has a fixed groove 45. The inner side of the fixed groove 45 is movably inserted with a movable blocking plate 46. A third handle 47 is fixedly connected to one side of the movable blocking plate 46.
[0038] The first collection box 40 and the second collection box 42 can collect the screened raw materials. At the same time, the second caster 39 can move the entire classification and collection mechanism 9. When it is necessary to take out the raw materials collected inside, the third handle 47 is moved upward, which drives the movable blocking plate 46 to move, so that the raw materials can be discharged to the outside through the fixed discharge port 43 and the guide block 44. The operation is convenient.
[0039] The working principle of this utility model is as follows: When the first electric telescopic rod 21 retracts, it can drive the first mounting block 18 to move, which in turn can drive the third connecting block 17, the second screen 13, the second connecting block 15, the movable connecting arm 16, the first connecting block 14, and the first screen 12 to shift. This allows the movable mounting block 11 to deflect inside the screening machine body 1, the movable connecting arm 16 to deflect between the first connecting block 14 and the second connecting block 15, and simultaneously the first mounting block 18 and the second mounting block 20 to deflect inside the third connecting block 17 and the fourth connecting block 19, thereby adjusting the first screen 12. The tilting direction of the second screen 13 is adjusted to adjust the overall adjustment of the screening mechanism 3. Then, the second electric telescopic rod 31 can push and pull the fixed connecting arm 32, driving the connecting end block 33 and the connecting sealing plate 34 to move, thereby opening and closing the connecting bottom frame 27, thus affecting the entire feeding mechanism 4. Therefore, during the overall use, the inside of the feeding mechanism 4 is filled with raw materials. When it is necessary to use the classification and collection mechanism 9 located on the right to collect materials, the adjustment screening mechanism 3 is adjusted so that the adjustment screening mechanism 3 can tilt to the right, and then the left side of the top of the screening machine body 1 is adjusted. The feeding mechanism 4 is adjusted so that the raw material on the left side is discharged downwards. At the same time, the movable insert plate 6 is pulled out from the inside of the limiting bottom block 5. Then, during the screening process, the screened raw material can move and be collected inside the classification and collection mechanism 9 and the movable collection mechanism 8 on the right side. When the classification and collection mechanism 9 on the right side is almost full, the tilt direction of the adjusting screening mechanism 3 is adjusted so that the adjusting screening mechanism 3 tilts to the left. At this time, the feeding mechanism 4 on the left side is closed and the feeding mechanism 4 on the right side is opened, so that the classification and collection mechanism 9 on the left side can collect the screened raw material. The material is collected, and the sorting and collecting mechanism 9 on the right side is replaced. When the movable collecting mechanism 8 needs to be replaced, first insert the movable insert plate 6 into the inside of the limiting bottom block 5 to block the fixed through groove 10. Then replace the movable collecting mechanism 8. After the replacement is completed, pull out the movable insert plate 6 again to collect the raw material. When the raw material collected inside the sorting and collecting mechanism 9 needs to be taken out, move the third handle 47 upward to move the movable blocking plate 46, so that the raw material can be discharged to the outside through the fixed discharge port 43 and the guide block 44. The overall structure is simple and the operation is convenient and quick.
[0040] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
