When disassembly is required, the nut 9 is directly removed and the stirring blade 7 can be pulled out. When the stirring blade 7 needs to be installed, the externally threaded rod 8 is first moved to the inside of the groove 6, and then the nut 9 is installed to fix it inside the limiting frame 5, which is very convenient to use.

[0031] A fixing frame 12 is welded to the top of the mixing bin 3, a fixing block 10 is welded to the side of the fixing frame 12, a shaft rod 11 is welded to the side of the fixing block 10, a shaft sleeve 13 is sleeved on the surface of the shaft rod 11, a fixing frame 14 is welded to the surface of the shaft sleeve 13, a cover plate 15 is welded to the other end of the fixing frame 14, a limiting groove 16 is provided at the bottom of the cover plate 15, a sealing frame 17 is provided on the top of the mixing bin 3, and the surface of the sealing frame 17 is embedded in the limiting groove 16. By installing the sealing frame 17, when the sealing frame 17 is embedded in the limiting frame 5, the sealing frame 17 can provide a sealing effect for the gap between the cover plate 15 and the mixing bin 3, so that fine fly ash will not overflow through the gap between the cover plate 15 and the mixing bin 3, and the sealing effect is strong when used.

[0032] A card slot 19 is provided at the top of the fixed frame 12, and a card frame 18 is carded inside the card slot 19. A sealing frame 17 is bonded to the top of the card frame 18. By installing the card slot 19, the card frame 18 can be carded using the card slot 19, which can provide a fixing effect for the sealing frame 17, so that the sealing frame 17 is fixed on the top of the fixed frame 12, which is very convenient to use.

At this time, the stirring rod 4 should be inserted into the limiting frame 5 until the external threaded rod 8 is embedded in the groove 6. Then, the nut 9 is installed on the surface of the external threaded rod 8. After the stirring blade 7 is fixed in the limiting frame 5, the fly ash to be mixed can be put into the mixing bin 3. Then, the cover plate 15 is rotated around the shaft 11 until it covers the top of the mixing bin 3. At this time, the sealing frame 17 will be embedded in the limiting frame 5. Then, the stirring device 2 is started to drive the stirring rod 4, and then the stirring blade 7 is driven to mix the fly ash. At this time, during the stirring process, the fly ash is mixed using the stirring device 2. The sealing frame 17 can provide a sealing effect for the gap between the cover plate 15 and the mixing bin 3, so that fine fly ash will not overflow through the gap between the cover plate 15 and the mixing bin 3. The sealing effect is strong during use. After the mixing is completed, the cover plate 15 is opened by the handle, and the mixed fly ash inside the mixing bin 3 is taken out. When the fly ash backfilling mixing device needs to be cleaned after long-term use, the nut 9 can be removed first, and then the mixing blade 7 can be directly pulled out from the inside of the limit frame 5. At this time, when cleaning the fly ash backfilling mixing device, it will not be blocked by the mixing blade 7, which is very convenient to use. After the cleaning is completed, the mixing blade 7 can be installed inside the limit frame 5.
