PROBLEM TO BE SOLVED: To provide a grain discharging apparatus for improving operating efficiency and work efficiency of a discharging auger, smoothing transportation, improving security of the transportation, suppressing occurrence of clogging, smoothing expansion and contraction and reducing cost. SOLUTION: This apparatus for discharging the grains is composed as follows. A transverse discharging auger 6 connected to a vertical elevating apparatus 5 for discharging the grains in a grain tank 4 is formed dividedly into a fixed auger 7 and a movable auger 8 mounted on the fixed auger 7 so as to freely expand and contract. A plurality of screw flights 25 on the movable side moving according to the expansion and contraction of the movable auger 8 are installed to compose expanding and contracting screw 20 in the movable auger 8. The screw flights 25 on the movable side during the transportation of the grains are moved so that the expanding and contracting screw 20 can be expanded and contracted. COPYRIGHT: (C)2003,JPO
