The return mechanism 3 includes a return box 31, a connecting box 32, a suction box 33 and a suction port 34. A connecting box 32 is provided on the bottom surface of the middle of the return box 31. The connecting box 32 is engaged and slid with the movable box 21. The connecting box 32 is engaged and slid with the movable box 21. The return mechanism 3 is driven by the connecting box 32 and the electric rod 22 to rise and fall. A suction box 33 is provided on the bottom surface of the connecting box 32. A suction port 34 is provided on the inner side of the suction box 33. The suction ports 34 are distributed in a ring. The suction ports 34 distributed in a ring are convenient for evenly collecting the cement fly ash generated at the warehouse opening of the grinding head bin 6.

[0026] As an improvement to the above solution, a motor 12 is provided on the top of the housing 11, a driving rod 13 is provided at the output end of the motor 12, and a fan blade 14 is provided on the outer side of the bottom of the driving rod 13. The motor 12 drives the fan blade 14 to rotate through the driving rod 13, so that the air inside the housing 11 can be discharged into the interior of the material guide mechanism 4. In this way, the suction port 34 at the bottom of the suction box 33 in the return mechanism 3 can generate suction, thereby achieving the purpose of collecting cement fly ash;

[0027] In this embodiment, a feed port 15 is provided at one end of the top of the shell 11. The setting of the feed port 15 facilitates the air communication in the return mechanism 3 and the movable mechanism 2 to allow the cement fly ash to enter the interior of the shell 11. An aggregate ring block 16 is provided at the bottom inner side of the shell 11. The conical surface formed in the middle of the aggregate ring block 16 can collect cement fly ash and send it into the aggregate box 17. An aggregate box 17 is provided on the bottom surface of the shell 11. A material guide slope is formed on the inner side of the aggregate box 17. The aggregate box 17 can send the collected cement fly ash and air into the interior of the material guide mechanism 4, so that the material guide mechanism 4 can send the cement fly ash into the interior of the grinding head bin 6.

[0028] The implementation principle of this embodiment 1 is as follows: when cement fly ash is generated at the warehouse mouth during the process of cement powder falling from the chute to the grinding head warehouse 6, the motor 12 drives the driving rod 13 and the fan blade 14 to rotate. When the fan blade 14 drives the air to flow, the multiple suction ports 34 opened on the bottom surface of the suction box 33 in the return mechanism 3 will generate suction to evenly collect the cement fly ash generated at the warehouse mouth of the grinding head warehouse 6. Then, the cement fly ash will follow the air through the collection box 17 and be sent into the material guiding mechanism 4. The material guiding mechanism 4 will send the collected cement fly ash into the interior of the grinding head warehouse 6, thereby solving the problem of cement fly ash polluting the environment while reducing the waste of cement fly ash. Example 2

[0029] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following content:

[0030] In order to enable the device to effectively store cement fly ash after collecting it, this embodiment provides the following design:

[0031] The material guide mechanism 4 includes a material guide box 41, a filter screen 42, and a material guide cylinder 43. The material guide box 41 is arranged on the side of the housing 11. The bottom side of the material guide box 41 is connected to the aggregate box 17. The bottom end of the material guide box 41 is provided with a material guide cylinder 43. The material guide cylinder 43 guides the cement fly ash into the interior of the grinding head bin 6. The material guide cylinder 43 extends into the interior of the grinding head bin 6. The side of the material guide box 41 is provided with a filter screen 42. The filter screen 42 filters the collected cement fly ash so that the cement fly ash in the material guide box 41 falls through the material guide cylinder 43 and enters the interior of the grinding head bin 6.

[0032] In this embodiment, a connecting rod 44 is provided in the middle of the inner side of the material guide box 41, and multiple groups of supporting rods 45 are provided on the side of the connecting rod 44. A force block 46 is provided on the top of the connecting rod 44. The force block 46 is located inside the vibration mechanism 5. The connecting rod 44 and the supporting rod 45 can assist the vibration mechanism 5 in vibrating the filter screen 42, so as to shake off the cement fly ash adsorbed and accumulated on the side of the filter screen 42 and affect the ventilation effect of the filter screen 42.

[0033] In this embodiment, the vibration mechanism 5 includes an installation box 51, a second motor 52, a turntable 53, an elastic strip 54 and an impact block 55. The installation box 51 is arranged on the top surface of the shell 11. The second motor 52 is arranged inside the installation box 51. The output end of the second motor 52 is provided with a turntable 53. The outer side of the turntable 53 is provided with an elastic strip 54. The end of the elastic strip 54 is provided with an impact block 55. The elastic strip 54 and the impact block 55 can rotate with the turntable 53, continuously impacting the force-bearing block 46, causing the filter 42 to vibrate.

[0034] The implementation principle of the second embodiment is as follows: after the grinding head return device collects cement fly ash, the cement fly ash will enter the material guide box 41 of the material guide mechanism 4 together with the air. After being filtered through the filter screen 42, the cement fly ash can be collected inside the material guide box 41. Then, the cement fly ash will fall and enter the grinding head bin 6 through the material guide cylinder 43, thereby achieving the purpose of recycling cement fly ash. In this process, after cement fly ash accumulates on the inside of the filter screen 42, the motor 2 52 in the vibration mechanism 5 drives the turntable 53 to rotate. At this time, the elastic strip 54 and the impact block 55 rotate with the turntable 53, and the impact block 55 will continuously impact the force block 46, so that the vibration is transmitted to the filter screen 42 through the connecting rod 44 and the support rod 45, thereby achieving the effect of shaking off the cement fly ash, thereby facilitating the grinding head return device to collect and return cement fly ash for a long time.
