[0045] In the implementation process, in the process of screening the gold powder, the gold powder is put into the screen cylinder 2, and then the vibrating screen 1 is started. The gold powder is screened by the vibration of the vibrating screen 1. After the vibrating screen 1 is started for a period of time, the screen mesh 4 will adsorb the gold powder, and the gold powder will be bonded together due to electrostatic action and the like. At this time, the motor 31 is started. The start of the motor 31 will drive the driving shaft 32 to rotate. Through the rotation of the driving shaft 32, the wind wheel 17 will be rotated through the action of the rotating frame 33. After the wind wheel 17 rotates, the wind power will be generated. The wind power will be transported into the air conveying pipe 8 through the connecting pipe 7. Through the action of the air conveying pipe 8, the wind power is transported into the shunt pipe 9. Then the wind power is transported into the multiple air outlet pipes 10 through the shunt pipe 9.

Further, when the wind power enters the air conveying pipe 8, the wind power also enters the communication pipe 27 through the air outlet hole 26. The wind power is transported into the air blowing pipe 23 through the communication pipe 27. Then the wind power will be blown to the blade 22. The blade 22 is rotated by the wind blowing, and the rotating cover 20 is rotated by the rotation of the blade 22. The rotating plate 19 is rotated by the rotation of the rotating cover 20. The air conveying pipe 8 is rotated by the rotation of the rotating plate 19, so that the shunt pipe 9 connected thereto is rotated, and the air outlet pipe 10 is rotated, so that the wind power is uniformly blown to the screen mesh 4, so that the gold powder on the screen mesh 4 is blown away. Wherein, in the process of rotating the air outlet pipe 10, the air outlet pipe 10 will extrude the rotating block 35. Through the extrusion of the rotating block 35, the rotating block 35 is rotated. In the process of rotating the rotating block 35, the connecting shaft 34 is rotated. When the connecting shaft 34 rotates, the torsional spring 38 is compressed. After the air outlet pipe 10 moves away from the rotating block 35, the connecting shaft 34 and the rotating block 35 are reset due to the action of the torsional spring 38. Through the reset action of the rotating block 35, the screen mesh 4 is impacted, so that the screen mesh 4 is vibrated, thereby further improving the cleaning ability of the screen mesh 4.

[0046] It is worth noting that in this scheme, the motor 31 is not always in the state of starting, and will start after a period of gold powder screening. It can be automatically started at regular intervals, and the automatic starting time can be adjusted according to the on-site situation.

[0047] It will be understood by those skilled in the art that the above-described embodiments of the application illustrated in the drawings and described above are merely exemplary and not limiting of the present application.
