The vacuum generator 211 is installed on the top of the powder segment 21, when the powder segment 21 is in a negative pressure state, powder is sucked into the powder segment 21 through the powder inlet pipe 26, and the end of the powder inlet pipe 26 is an anti-blocking powder suction head 261. The valve section 22 is the area in the powder silo 2 in which the valve is arranged, which valve functions as in the prior art, i.e. selectively blocks the passage of powder in the powder silo 2. The powder supply section 24 is divided into an upper conical pipe part and a lower waist-shaped powder barrel part provided with a stirring device, a material level sensor is arranged in the powder supply section, a high-level sensor and a low-level sensor are arranged in the powder supply section, an observation window 27 is further arranged on the top wall of the waist-shaped powder barrel part, and the observation window 27 adopts a commercially available flange window with a brush. The breathing tube 25 connects the powder section 21 and the powder supply section 24, and the inner cavity of the powder supply section 24 exchanges air with the outside through the air exchange filter 28, so that the powder section 21 and the powder supply section 24 which are alternately changed by positive pressure and negative pressure can share one air exchange filter 28, obviously, the air exchange filter 28 is arranged at the powder section 21, so that the inner cavity of the powder section 21 exchanges air with the outside through the air exchange filter 28, and the purpose can also be achieved. The powder sieving section 23 is arranged between the valve section 22 and the powder supply section 24, and three rod members 29 which are circumferentially arranged at intervals of 120 degrees are adopted for rigid connection between the valve section 22 and the powder supply section 24.
