[0023] Preferably: the extension mechanism includes: a surface thread 12, a thread groove 13, an extension tube 14, a sealing ring 15 and a slot 16, a surface thread 12 is provided on the outer surface at one end of the discharge port 4, the outer surface of the surface thread 12 is connected to the thread groove 13, the thread groove 13 is provided on the inner side of one end of the extension tube 14, a sealing ring 15 is connected to the inner surface at one end of the extension tube 14, and one end of the sealing ring 15 extends into the slot 16 provided on the outer surface at one end of the discharge port 4.

[0024] During specific use, an extension tube 14 of appropriate size is selected according to the height of the discharge port 4, and the extension tube 14 is screwed onto the surface thread 12 arranged on the outside of the inlet and outlet port 4 through the thread groove 13. In this way, the position of the extension tube 14 will be installed at the discharge port 4. At the same time, after the extension tube 14 is installed, the sealing ring 15 arranged on the inner side will move and engage into the groove 16, thereby increasing the sealing between the extension tube 14 and the discharge port 4, so that the material discharged from the discharge port 4 will enter the extension tube 14 and then be discharged from the other end of the extension tube 14.

[0025] Preferably, the electric push rod 6 is electrically connected to an external power source via a control switch, and the movable plate 7 is slidably connected to the base 1 via the movable groove 5 .

[0026] During specific use, the electric push rod 6 can be controlled by a switch, and the movable end of the electric push rod 6 can drive the movable plate 7 to move in the movable groove 5.

[0027] Preferably, the slide block 8 is slidably connected to the base 1 via the slide groove 9 .

[0028] During specific use, the slider 8 can slide in the slide groove 9 to ensure the stability of the movable plate 7 when it moves, and at the same time limit the movement process of the movable plate 7 to prevent the movable plate 7 from completely moving out of the movable groove 5.

[0029] Preferably, the extension tube 14 is threadedly connected to the surface thread 12 through the thread groove 13 .

[0030] During specific use, the extension tube 14 can be screwed onto the surface thread 12 provided on the outlet 4 through the thread groove 13 , so that the position of the extension tube 14 will be fixed on the outlet 4 .

[0031] Working principle: When using the material screening device for ultrafine powder production, the operator places the ultrafine powder material into the screening bin 2 through the feed port 3, starts the vibration motor on the base 1 and the ultrasonic generator set on the screening bin 2, and then screens the material in the screening bin 2, allowing materials of different particles to be discharged from the discharge port 4. In this way, the material discharged from the discharge port 4 will slide into the storage device placed below the feed port 4. When the storage device is too far away from the discharge port 4, the material that slides out will enter the storage device. Sputtering may occur, which may cause part of the material to spill out and cause a waste of resources. Here, an extension tube 14 needs to be installed. It should be particularly noted that the extension tube 14 can be customized in different sizes according to needs. The extension tube 14 of appropriate size is selected according to the height of the discharge port 4, and the extension tube 14 is screwed onto the surface thread 12 arranged on the outer side of the inlet and outlet 4 through the thread groove 13. In this way, the position of the extension tube 14 will be installed at the discharge port 4. At the same time, after the extension tube 14 is installed, the sealing ring 15 arranged on the inner side will move and engage into the card groove 16, thereby increasing the sealing between the extension tube 14 and the discharge port 4. In this way, the material discharged from the discharge port 4 will enter the extension tube 14 and then be discharged from the other end of the extension tube 14. This operation can change the distance between the material outlet and the storage device to avoid splashing of the material when discharging the material. Secondly, when the screening device needs to be moved, the electric push rod 6 is started to drive the movable plate 7 to move in the movable groove 5 at the movable end of the electric push rod 6. When the movable plate 7 moves, the slider 8 will also slide in the slide groove 9 to ensure Ensure the stability of the movable plate 7 when it moves, and at the same time limit the movement process of the movable plate 7 to prevent the movable plate 7 from moving out of the movable groove 5. In this way, the movable plate 7 will drive the pulley 10 to move downward, so that the position of the pulley 10 exceeds the support ring 11, so that the pulley 10 will support the entire screening device, so that the operator can move the screening device through the pulley 10. When the screening device moves to the specified position, it will move upward from the driving pulley 10, so that the support ring 11 will support the screening device again, ensuring the stability of the screening device when it is in use.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
