<P>PROBLEM TO BE SOLVED: To provide a small grain selector, only unit of which can do the job to select three different kinds such as sized grain of a large diameter, a medium size grain of a rather smaller diameter than the sized grain, and grain tailings or the like of a smaller size than the medium size grain, and also can reduce an installation space. <P>SOLUTION: A first selection netted cylinder 10 for removing fine crushed grains. grain tailings of a small diameter and fine foreign substances such as sand and dust which are mixed in the grains, and a second selection netted cylinder 11 for removing the medium size grain of a rather smaller diameter than the sized grain, from the residual grains obtained by removing by the first selection netted cylinder 10. In addition, a selection netted cylinder part 3 includes the first selection netted cylinder 10 and the second selection netted cylinder 11 arranged continuously in one piece, and is installed slopingly. Meanwhile, a stirring member 4 is arranged rotatably inside the selection netted cylinder part 3, and further, a grain hoisting part 6 which hoists and discharges to the outside of the grain selector the sized grain of large diameter selected by the first selection netted cylinder 10 and the second selection netted cylinder 11, is installed at the open end 11a, on the second selection netted cylinder 11 side, of the selection netted cylinder part 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
