Because the air blowing port 705 is connected with an air pipe through the outside of the air inlet 704, air can be blown through the air inlet 704 through the air blowing port 705. When chips are conveyed to pass through each height filter, the installation height of the air blowing positioning adjusting groove 702 in the air blowing positioning block 701 of each height filter and the vibration disc body 1 can be adjusted by only adjusting the installation height of the air blowing opening 705 on the vibration disc body 1 to adjust the air blowing height of the vibration disc feeding track 2, so that the chip blowing height adjusting device can be suitable for blowing chips with different heights, and the purpose of strong universality is achieved; if it is needed to screen small-sized chips, the blowing height of the blowing port 705 can be reduced by only reducing the mounting height of the blowing mosaic block 703 and the vibrating tray body 1, so that it is suitable for screening small-sized chips. When a large-size chip needs to be screened, the height of the air blowing port 705 can be increased by only increasing the installation height of the air blowing mosaic block 703 and the vibration disc body 1, so that the screening device is suitable for screening the large-size chip; the unqualified product is obtained when the height of the chip conveyed by the vibrating tray exceeds the height of the air blowing port 705, and the unqualified product is blown back into the vibrating tray body 1 when the air is blown out from the air blowing port 705.
