The top of the pushing slide plate 6 is fixedly connected to the bottom of the screw rod 8. A driving member for driving the screw sleeve 7 to rotate is arranged on the fixed plate 1. Start the driving member to make the output shaft of the driving member rotate clockwise or counterclockwise, which is convenient to drive the screw sleeve 7 to rotate clockwise or counterclockwise, thereby driving the screw rod 8 to rotate downward or rotate upward, and thus can synchronously drive the pushing slide plate 6 to rotate downward or rotate upward.

[0023] Specifically, the driving member includes a driving motor 9 fixedly installed on the top of the fixing plate 1 through a mounting frame. The output shaft of the driving motor 9 is in transmission connection with the screw sleeve 7 through a transmission assembly 10. By starting the driving motor 9, the output shaft of the driving motor 9 rotates clockwise or counterclockwise. Through the transmission cooperation of the transmission assembly 10, it is convenient to drive the screw sleeve 7 to rotate synchronously. The transmission assembly 10 can be set in the transmission forms such as belt and pulley, sprocket and chain, etc.

[0024] Specifically, the fixing plate 1 includes a rotating mechanism for driving the quantitative tube 3 and the sealing plate 5 to rotate. The rotating mechanism includes a rotating shaft 4 rotatably connected to the fixing plate 1. The rotating shaft 4 is fixedly connected to the quantitative tube 3 and the sealing plate 5. A gear 15 is fixedly installed at the top of the rotating shaft 4. A rack 16 that is in meshing engagement with one side of the gear 15 and is in guiding sliding fit with the fixing plate 1 is provided. It also includes a horizontal driving cylinder 17 fixedly installed at the top of the fixing plate 1 and whose output end is fixedly connected to the rack 16. By starting the horizontal driving cylinder 17, the output shaft of the horizontal driving cylinder 17 extends or retracts, so that the rack 16 drives the gear 15 to rotate clockwise or counterclockwise, facilitating driving the rotating shaft 4, the quantitative tube 3 and the sealing plate 5 as a whole to rotate clockwise or counterclockwise.

[0025] Specifically, it further includes a lifting mechanism for driving the plugging slide plate 11 to lift. The lifting mechanism includes a quantitative lifting driving cylinder 12 fixedly installed on the fixing plate 1. The bottom output shaft of the quantitative lifting driving cylinder 12 is fixedly connected to the bottom of the plugging slide plate 11 through a U-shaped frame 13. A guiding frame 14 that is in vertical sliding fit with the U-shaped frame 13 is fixedly connected to the bottom of the fixing plate 1.

[0027] In use, place the fixing plate 1 on the feeding port of the fixed powder processing equipment, and insert the metering tube 3, the plugging slide plate 11 and the scraping wall and pushing mechanism into the feeding port. Then, adjust the height of the top end of the plugging slide plate 11 to be flush with the bottom end surface of the metering tube 3. Next, add fixed powder into the metering tube 3 through the feeding tube 2. When a certain amount is added, by repeatedly moving the plugging slide plate 11 upwards, observe the overflow situation from the feeding tube 2 to ensure that the metering tube 3 is full of fixed powder. Then, restore the plugging slide plate 11 to the height where its top end surface is flush with the bottom end surface of the metering tube 3. Then, quickly rotate the metering tube 3 and the sealing plate 5 so that the sealing plate 5 blocks the bottom end of the feeding tube 2. At the same time, most of the solid powder in the metering tube 3 falls down. When the metering tube 3 rotates below the scraping wall and pushing mechanism, scrape all the remaining fixed powder on the inner wall of the metering tube 3 through the scraping wall and pushing mechanism.
