[0041] The power mechanism is connected with the rotating shaft 13.

[0042] By means of the above structure: through the transmission of the structure, the double-edged knife 14 can be used to crush the material discharged from the feed hopper 1 into the crushing box 2, and the agglomerated material can be cut into powder to avoid material agglomeration, and the fine powder can be used to facilitate nitrogen transportation.

[0043] See also Figure 3 The power mechanism includes a cylinder 9, an articulated rod 10, a gear disc 11 and a pinion 12. The output end of the cylinder 9 is hinged to the left end of the articulated rod 10, and the right end of the articulated rod 10 is hinged to the bottom end of the gear disc 11. The teeth of the gear disc 11 are engaged with the teeth of the pinion 12. The axis of the pinion 12 is keyed to one end of the rotating shaft 13. When the air pressure control of the cylinder 9 is turned on, the cylinder 9 can drive the articulated rod 10 to move back and forth, the articulated rod 10 can drive the gear disc 11 to rotate, and the gear disc 11 can drive the pinion 12 to rotate. The size of the gear disc 11 is larger than that of the pinion 12, which can produce an acceleration effect on the pinion 12, and the pinion 12 can drive the rotating shaft 13 to rotate.

[0044] See also Figure 2 The surface of the cylinder 9 is connected to the side bolts of the crushing box 2, the toothed disc 11 is rotatably connected to the crushing box 2, the cylinder 9 is fixed by the crushing box 2, and the cylinder 9 drives the hinged rod 10 to move. The toothed disc 11 is rotatably set with the crushing box 2 through the bearing.

[0045] See also Figure 1 The top of the circulation pipe 8 is connected to a nitrogen replenishing pipe 15, which is close to the blower 5. The nitrogen replenishing pipe 15 is used to replenish nitrogen into the interior of the circulation pipe 8 to facilitate the blower 5 to extract nitrogen.

[0048] Example 2

[0049] The difference between this embodiment and the first embodiment is that the cylinder 9, the articulated rod 10 and the toothed disc 11 are replaced by a motor and a large gear keyed to the motor output end. The motor can drive the small gear 12 to rotate through the large gear, but the motor and the large gear are not convenient for driving the double-edged knife 14 to rotate forward and reverse quickly. Therefore, the present application preferably adopts the cylinder 9, the articulated rod 10 and the toothed disc 11.

[0050] It should be noted that the specific types of blower 5, gas-gas separator 6, dust collector 7 and cylinder 9 to be used are selected by relevant technical personnel familiar with the field, and the above blower 5, gas-gas separator 6, dust collector 7 and cylinder 9 are all existing technologies and will not be elaborated in this solution.

[0051] The working principle of the utility model is as follows: the ton bag of materials is hoisted into the dust-free feeder by the electric hoist for dust-free unpacking. The unpacked materials fall into the feed hopper 1. Under the influence of gravity, the materials fall into the interior of the crushing box 2. The air pressure control of the cylinder 9 is turned on. The cylinder 9 can drive the hinged rod 10 to move back and forth. The hinged rod 10 can drive the gear plate 11 to rotate. The gear plate 11 can drive the small gear 12 to rotate. The size of the gear plate 11 is larger than the size of the small gear 12, which can produce an acceleration effect on the small gear 12. 12 can drive the rotating shaft 13 to rotate, and the rotating shaft 13 can drive the double-edged knife 14 to rotate. The double-edged knife 14 can crush the material discharged from the feed hopper 1 inside the crushing box 2. The power of the blower 5 is turned on, and the blower 5 extracts nitrogen from the inside of the circulation pipe 8, and then presses the nitrogen into the conveying pipe 4. When the nitrogen passes through the connecting pipe 3, suction is generated, and the material is carried into the conveying pipe 4. Then, it is separated by the material-gas separator 6, and the material is discharged downward into various equipment such as the reactor. The separated nitrogen is circulated again through the circulation pipe 8.

[0052] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
