By this method, small rice sorting work is efficiently performed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grain sorting device for sorting mixed rice of paddy and brown rice using a rotating sorting cylinder having a large number of pot holes on its inner circumferential surface. It is something.

[Prior art]

There is a grain sorting machine that sorts a mixed rice of paddy and brown rice by rotating a rotary sorting tube, which has a number of pot holes on its inner circumferential surface, around a horizontal axis.

[Problem that the invention seeks to solve]

In the conventional device, inside this rotary sorting tube, a finishing rice gutter is installed horizontally in the longitudinal direction to receive the brown rice that has been pumped up through the pot hole of the rotary sorting tube, and the mixed rice of paddy and brown rice is placed at the sorting start end of the rotary sorting tube. While flowing from the side to the sorting end side, brown rice with short grain length is pumped up high and falls into the finishing rice gutter above, while unhulled rice with long grain length is pumped up low and falls again into the rotating sorting tube. While repeating such sorting action, the rice is sorted while flowing from the supply side to the discharge side, and the sorted rice is discharged from the discharge side end of the rotary sorting tube.

Although the sorting is carried out as described above, in the conventional apparatus, nothing was provided on the outer periphery of the rotary sorting cylinder, and this part did not contribute to the sorting work. Therefore, the present invention aims to improve sorting efficiency and sorting accuracy by effectively utilizing the outer periphery of the rotary sorting cylinder and using it in a device for sorting brown rice or a device for sorting out rice that has fallen off from the scraping section.
