(c) Problems to be Solved by the Invention The present invention provides a single-hulled technology for removing millet from grains before sorting through the pot holes as in the conventional method. In addition to the configuration, a primary rotating sorting cylinder and a secondary rotating sorting cylinder are arranged above and below, and the rough sorting is carried out by the primary rotating sorting cylinder, and the material is finished sorted by the secondary rotating sorting cylinder, improving sorting efficiency and sorting. It has a structure that improves accuracy, and during the sorting process, the millet mixed in with the grains is sorted and taken out, and when the millet is taken out, the grains supplied to the primary and secondary rotary sorting cylinders are The object of the present invention is to provide small rice which can be taken out in one batch after receiving overflowing from the grain supply side, with a simple structure.

B.) Means for Solving the Problems Therefore, the present invention provides a primary rotary sorting cylinder having a rough sorting gutter on the grain receiving side of the finishing gutter and having a large number of pot holes formed in its inner circumferential surface; The following technical measures are applied to a grain sorting machine that is constructed by disposing upper and lower secondary rotary sorting cylinders with a finishing trough and a large number of potholes formed on the inner circumferential surface. .

That is, the grain supply sides of the primary rotary sorting cylinder and the secondary rotary sorting cylinder are on the same side, and on the grain supply side, the upper finishing receiving gutter and rough sorting receiving gutter are connected to the lower finishing receiving gutter and the secondary rotary sorting. In addition to communicating with the inside of the barrel, the lower finish receiving trough and each grain supply side of the secondary rotary sorting barrel are formed with a sorting net through which millet is leaked, and the millet is placed under the sorting net on the grain supply side. A take-out receiving trough is installed to receive the grains overflowing from the grain supply side of each rotary sorting cylinder and the small rice leaking through each sorting net, and to take them out all at once.

(e) Effect With this configuration, for example, mixed rice of brown rice and paddy is placed in the upper row.
Next, when the grains are fed to the grain supply side in the rotating sorting barrel, the brown rice and small rice in the mixed rice are transferred from the grain receiving side to the finishing tray by the lifting action of the pot hole, and the paddy is slightly larger than the brown rice. The roughly sorted mixed rice with a high proportion of paddy mixed in is received into the rough sorting receiving trough, and the brown rice and small rice received in the finishing receiving trough are transferred from the grain supply side to the secondary rotary sorting cylinder in the lower stage. The mixed rice in the rough sorting receiving trough is fed into the finishing receiving trough, which is internally shaped, and the mixed rice in the rough sorting receiving trough is supplied into this secondary rotating sorting cylinder. As a result, the small rice that is supplied to the lower finishing receiving trough leaks from the sorting net that forms the grain supply side of this finishing receiving trough, and also leaks from the sorting net that forms the grain supplying side of the secondary rotating sorting cylinder. The rice that leaks and gets mixed into the mixed rice from the rough sorting receiving trough that is supplied into the secondary rotary sorting cylinder leaks from the sorting net of the same rotary sorting system and is sent to the milled rice take-out receiving trough. It is then received by the operator and taken out of the aircraft. The mixed rice that has passed over the sorting net on the grain supply side of the rotary sorting cylinder in the lower stage is subjected to the sorting action by the lifting action of the seventh pot hole, and the brown rice is received in the finishing receiving trough, and the upper stage from which the small rice is removed. The rice is combined with brown rice from the finishing receiving trough and taken out of the machine.

In addition, among the mixed rice supplied to the grain supply side of the primary rotary sorting cylinder in the upper stage, the rice that overflows from that supply side and the two in the lower stage
The grain supply side of the next rotary sorting cylinder is supplied from the upper rough sorting receiving trough, and some of the mixed rice with a high mixing ratio of paddy overflows from the supply side, and is caught in the above-mentioned small rice take-out receiving trough and is transferred to the sorting net. It joins with the small rice that has leaked out and is taken out and collected all at once.
