As shown in Figures 1 and 2, a dust-free powder feeding hopper of the present invention includes a hopper 11, a conveying pipe 13, a conveying screw 12 and a motor 15. The side plate on the right side of the hopper 11 is a rubber plate 8. One end of the conveying pipe 13 is installed on the inner wall surface of the hopper 11 through a living hinge, and the other end is inclined through the rubber plate 8 and extends to the outside world. The lower end of the conveying pipe 13 is provided with a feeding hole 6, and the upper end of the feeding hole 6 is adhered and fixed with a horn cover 7 that communicates with the feeding hole 6, and the port on the upper end of the horn cover 7 is adhered and fixed on the inner wall of the hopper 11. A screw hole is provided on the bottom surface, and a screw 4 is threaded in the screw hole. The upper end of the screw 4 is arranged in a hemispherical structure and is in contact with the bottom surface of the conveying pipe 13. The conveying pipe 13 is tilted by the screw 4. The handwheel 3 is installed, the upper end of the conveying pipe 13 is provided with a discharging hole 14, the lower end of the discharging hole 14 is hot-melted and fixed with a discharging pipe 17, and the outer wall surface of the lower end of the discharging pipe 17 is hot-melted and fixed with a connecting ring 19. The connecting ring A discharge pipe 18 is sleeved outside the 19, the discharge pipe 18 is threadedly connected with the connecting ring 19, and a cover plate 16 is installed on the outside of the discharge pipe 18.

In this embodiment, a bearing is embedded in the left end of the conveying pipe 13 , the conveying screw 12 is arranged inside the conveying pipe, the motor 15 is installed on the upper end of the conveying pipe 13 , and the rotating shaft of the motor 15 extends into the conveying pipe 13 , and It is connected with the conveying screw 12 through the coupling, and the other end of the conveying screw 12 is installed in the inner ring of the bearing.
