PROBLEM TO BE SOLVED: To provide a grain weighing bagging machine in which a relative positional relationship of a feeding opening, a storage tank and a plugging pipe can be positionally changed to the left or right like a right hand state and a left hand state by a longitudinal horizontal half-turn work to a machine base of a grain lifting cylindrical body and the selective opening and closing work of a pair of front and rear receiving openings using a blocking plate, and thereby it is compatible with a situation of an installation location and the flexibility of installation can be increased only as for it.SOLUTION: A grain lifting cylindrical body 2 is provided in a longitudinally horizontally half-turned manner to a machine base 1. A receiving opening 15 capable of receiving the grain G from a return opening part 12 of a storage tank 5 in the lower part of the grain lifting cylindrical body is disposed when a grain lifting cylindrical part 4 is longitudinally horizontally half-turned to the machine base in the lower part of a front wall plate 2a of the grain lifting cylindrical body, and a blocking plate 16 capable of selectively blocking a pair of front and rear receiving openings 14, 15 is disposed detachably.SELECTED DRAWING: Figure 1
