Principle of operation

When the dust-containing material conveying device is used for conveying materials containing dust, the dust raised at the material receiving point of the conveying belt 2 is limited in the material guide groove 3, and the flow of dust-containing air is gradually weakened through the dust blocking curtain 8, so that the dust is naturally settled on the conveying belt 2; when the material quantity conveyed by the blanking pipe 4 is large, the opening degree of a valve 11 on the communicating pipe 9 is adjusted, and air at a material receiving point is guided to the vicinity of a discharge opening so as to balance the gas pressure in the material guide chute 3, thereby preventing air containing dust from flowing out from the discharge end quickly and reducing the dust blocking effect of the dust blocking curtain 8; air containing dust passing through the communicating pipe 9 is filtered by a dust filter 10 and then continuously passes through a dust blocking curtain 8 at the rear end of the communicating pipe 9, so that the dust in the air is further settled;
