The invention provides for a loose material conveying device, comprising a bowl-shaped, fixed bottom chute for receiving the material to be transported, and a series of conveying members mounted on a mobile alternating frame. The inventive device is characterized in that each conveying member (2; 100) comprises at least two blades (10, 11, 12; 110, 111, 112; 110', 111', 112') placed side by side, extending to a different depth in the chute, and in that the depth to which the superimposed blades extend in the said chute decreases from the previous blade (facing the material conveying sense) (12; 112; 112') to the subsequent blade (opposite to the material conveying sense) (10; 110; 110'). The invention is applied e.g. to the conveying of powder, granular or pasty material. |
