[0002] The ultrasonic vibrating screen is a common device for separating particles of different sizes, and the metal alloy powder is sieved by the ultrasonic vibrating screen to separate coarse and fine metal alloy powder. The metal alloy powder reaches the screen in the interior of the ultrasonic vibrating screen through the feeding port, the ultrasonic vibrating screen generates a low-amplitude, high-frequency vibration of the screen through the ultrasonic transducer, so that the metal alloy powder on the screen vibrates on the screen, thereby achieving the sieving effect.

The driving slave gears 47 are integrally formed on the side wall of the corresponding rotating ring 16.

[0048] With reference to Figure 4 , Figure 5 and Figure 6 When the swing motor 31 is started, the swing motor 31 drives the driving worm wheel 41 to rotate, which in turn drives the driving worm 42 to rotate. Then, the first gear 43 and the second gear 44 are in mesh with each other, so that the rotating ring 16 above the sieve plate 12 is rotated.

[0049] With reference to Figure 7 , Figure 8 , Figure 9 The sealing member 2 comprises a sealing motor 21, a sealing gear 22, a sealing rack 23, and a plugging rod 24. The inner wall of the vibrating sieve barrel 1 is provided with a placing cavity 18. The sealing motor 21 is connected to the inner wall of the placing cavity 18 through bolts. The sealing gear 22 is welded to the output end of the sealing motor 21. The sealing rack 23 is slidably connected to the inner wall of the placing cavity 18.

The other belt pulley 7132 is welded to the side wall of the control rod 712. The belt 7131 is sleeved on the two belt pulleys 7132.

[0057] With reference to Figure 2 and Figure 10When the control motor 711 drives the control rod 712 to rotate, the control rod 712 drives the corresponding mounting rod 721 to rotate through the belt pulley 7132 and the belt 7131, the mounting rod 721 drives the abutting rod 722 to rotate synchronously, and the abutting rod 722 drives the top rod 724 to move along the length direction of the inner wall of the limiting groove 611 through the shaking rod 723; so that the collection tank 132 is lifted by the top rod 724, so that the collection tank 132 moves away from the base 6, and the elastic element 725 is stretched at this time; when the control rod 712 continues to rotate, the top rod 724 is separated from the abutting rod 132, and the collection tank 132 is shaken along the inner wall of the moving groove 61 under the action of the elastic element 725; so that the metal alloy powder collected in the collection tank 132 is dispersed, and the gap between the metal alloy powder is reduced, thereby increasing the collection amount of the collection tank 132.

[0058] The implementation principle of the ultrasonic vibration sieve for metal alloy powder is that when the prepared metal alloy powder enters the inside of the sieve barrel 1 through the feeding pipe 11 and falls on the sieve plate 12, the vibration piece 15 drives the sieve barrel 1 to vibrate; then the swing motor 31 drives the swing ring 32 to rotate, so that the sleeve pipe 33 moves up and down on the pushing plate 141, and the pushing plate 141 swings on the fixed rod 14 under the action of the sleeve pipe 33; so that the pushing plate 141 pushes down the metal alloy powder accumulated on the sieve plate 12, so that the metal alloy powder accumulated on the sieve plate 12 is dispersed; the sieved coarse metal powder is collected in the corresponding collection tank 132 through the first discharge pipe 13, and the sieved fine metal powder is collected in the corresponding collection tank through the second discharge pipe 131, thereby completing the screening work of the metal alloy powder through the ultrasonic vibration sieve, and effectively improving the screening efficiency of the ultrasonic vibration sieve for the metal alloy powder.

[0059] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
