The operation of the above configuration will be explained below.

When the mixed size grains are fed to the supply hopper 8 of the vertical sorting device and the device is started, the porous wall sorting cylinder 7 and the rotating spiral 6
and rotate at different speeds in the same direction, the mixed grains flow down from the feed hopper 8 and flow onto the spiral 19 of the inclined rotating helix 6 to form a grain layer,
Upon contact with the high-speed rotating spiral 19, each grain receives centrifugal force and is biased towards the porous wall sorting tube 7 and drifts in a scattering manner, and small grains pass through the holes of the porous wall sorting tube 7. Through the fine grain chamber 29
The large grains (sorted grains) come into contact with the sorting cylinder 7 rotating at a low speed, and due to the contact force, they revolve in the opposite direction.
Moreover, the small grains mixed with the replaced grains due to the drifting flow in the opposite direction are discharged from the through hole in the same manner as described above by the centrifugal force that is applied next, and are discharged into the fine grain chamber 29. The particles on the spiral blades 9 gradually move obliquely downward due to the rotational force of the spiral body 6 and accumulate at the bottom of the cylinder while passing through the porous wall sorting cylinder 7. The small grains in the fine grain chamber 29 are transported by the wing pieces 30 and removed from the machine through the grain size adjustment outlet 31.

Next, when the porous wall sorting cylinder 7 is extracted from the vertical machine frame 1 and replaced in order to sort other grains with different grain sizes depending on the variety, production area, growing conditions, etc., the vertical machine When the supply hopper 8 provided at the top of the frame 1 is detached from the machine frame 1 by screwing off the mounting bracket 23, the vertical support shaft 12 provided at the top of the rotating helix 6° is connected to the bearing fixed to the supply hopper 8. After separating from the section 25, the upper part of the vertical machine frame 11 is opened.

The locking portion 27 of the sorting tube 7 is disengaged from the engaging portion 26 of the porous wall sorting n7, and the porous wall sorting n7 can be lifted and taken out of the vertical machine frame 1. Subsequently, when replacing the porous wall sorting tube 7A with a new porous wall sorting tube 7A, the installation work will be completed by carrying out the above-mentioned removal operation of the sorting tube in the reverse order, so the details of that work will be omitted. do. In this embodiment, when the spiral blades 9 of the rotating spiral body 6 are lifted, the polygonal opening of the rotation locking part 14 provided on the lower wall surface 13 of the rotating spiral body 6 is opened at the shaft end of the rotating main shaft 5. It can be detached from the rotating locking body 15 and taken out to the outside of the vertical machine frame 1 in the same way as the sorting tube 7. Further, the rotary disk body 3 loosely fitted onto the rotating main shaft 5 can be easily taken out of the machine by unscrewing the screw shaft 21.
