DEVICE FOR CONTAINER FILLING WITH POWDER PRODUCTS

FIELD: powder material packing equipment, particularly to pack flour, grain and so on in containers with the use of high-capacity plants. ^ SUBSTANCE: device comprises auger feeders, which provide rough and precise material metering and have augers arranged in transportation pipes in which inlet and outlet orifices are created. Outlet orifices of conveying pipes of rough and precise metering feeders are communicated with each other. Axis of precise metering feeder auger is below axis of rough material metering feeder and distance between the axes is 0.51-1.3 of auger diameter sum. Conveying pipe of precise material metering feeder communicates with that of rough material metering feeder through inlet orifice of precise material metering feeder. Vertical projection of inlet orifice of rough material metering feeder onto horizontal plane encloses inlet orifice of precise material metering feeder, wherein the overlapped area is 0.2-0.8 of that of inlet precise material metering feeder orifice. Lead of rough material metering feeder in overlapped area is 0.2-0.5 of length thereof. Diameter of conveying pipe of precise material metering auger is 0.2-0.6 of that of rough material metering auger. Ratio of volumes defined by auger turns of precise and rough material metering feeders are within the limits of 1:7 - 1:12. ^ EFFECT: increased packing speed and accuracy, prevention of material caking and "tunnel" forming around auger of both auger feeders. ^ 3 dwg
