PURPOSE:To weigh grains in a quantitative measure from a hopper without breakage and to feed to the next process with no residue, using air transportation. CONSTITUTION:A cylindrical rotary measure 3 is fitted in a box 2 provided in the rectangular opening 1' of a rectangular hopper 1 for grains. A cylindrical space 4 run in parallel with the measure 3 is provided in the box 2 at the lower part of the measure 3. A dropping guide groove interconnected to the cylindrical space 4 from the rotary measure 3 is provided. A short cylinder having a spiral groove is fitted into the space 4 from one end side of the cylindrical space 4. An air suction tube is connected to the other end side of the space 4. Thus, formation is made to suck air from one end toward the other end. |
