The residual grain extraction port is opened over substantially the entire width of the bottom plate, and the residual grain extraction port is opened and closed by a single cover plate to discharge the grains in the machine body at one time.

In the first place, the disc sorter requires a certain amount of grain inside the machine body, and sorting cannot be done without forming a fluidized bed that is circulated by the rotation of the sorting disc. It has a drawback that the amount of residual grains is larger than that of other sorters.

That is, even in the above-mentioned applied ones, the amount of residual grain is also large.

(C) Problems to be Solved by the Invention In the present invention, the sorting operation is completed because the disc sorter cannot perform sorting unless the fluidized bed is formed by the rotation of the sorting disc as described above. In order to eliminate the disadvantage that the amount of residual kernels at the time is larger than that of other sorters, the sorting operation is enabled even when the sorting work is almost finished, and the amount of residual grain at the end is It was invented mainly for the purpose of making it extremely small, and also for convenience when there is a clogging phenomenon or abnormality in the fuselage during sorting work or when cleaning the fuselage. is there.

A disc-type sorting machine for sorting brown rice and paddy during fluid transfer toward the left-hand side while opening a residual grain extraction port over substantially the entire width of the bottom plate constituting the body of the disc-type sorting machine. The following technical measures are to be taken in the case where a lid plate that can be opened and closed is attached to the accumulated grain outlet. In other words, the lid plate is divided into a feed gutter and a discharge gutter, and the discharge side lid plate can be opened and the supply side lid plate and the discharge side lid plate can be simultaneously opened. .

(E) Function According to the disk type sorting machine configured as described above, first, the residual grain extraction port is closed by the whole of the supply side cover plate and the discharge side cover plate, and the mixed rice is sequentially supplied from the machine feed. When it is supplied, the mixed rice is fed by the rotation of the sorting disc, its upward rotation is eccentric to the waft, and it circulates to form a fluidized bed while the discharge flows to the wa The rice is picked up and taken out from the gutter, and the paddy is not picked up even to the salt rice receiving gutter and falls on the way and the discharge is taken out so that it is sorted into brown rice and paddy.

When an abnormality such as clogging of mixed rice occurs during this sorting operation, the entire supply-side cover plate and discharge-side cover plate are opened at the same time, and the mixed rice inside the machine is discharged to the outside of the machine. To do.

In addition, when the sorting operation is almost completed, the amount of mixed rice supplied into the body is reduced and the fluidized bed becomes small in size, which makes sorting difficult or impossible. At this time, if the discharge side cover plate is opened, the waste remaining in the discharge will be discharged to the outside of the machine, and the sorting width will be reduced to only the feed and the fluidized bed will not be easily downsized. When the supply is continued, the cover plate on the supply side is finally opened so that the supply trapped in the trap is discharged to the outside of the machine.

When cleaning the machine body, the supply side cover plate and the discharge side cover plate are opened at the same time.
