Description

[Detailed description of the invention] "Industrial application field" This invention supplies mixed rice that has been hulled using a huller, etc., into a sorting cylinder that rotates continuously in one direction, and the mixed rice passes through the cylinder. This invention relates to a grain rotary sorting device that separates brown rice and paddy through the rotary sorting action of a moving cylinder.

``Prior art'' Conventionally, as shown in Japanese Utility Model Application No. 189379/1983, there was a technique in which mixed rice was introduced into the sorting tube through a chute and brown rice was taken out from inside the sorting tube through a brown rice gutter. .

``Problems to be solved by the invention'' However, since the prior art simply installed the chute and brown rice gutter inside the sorting cylinder, the input amount of mixed rice was reduced in order to improve the sorting throughput. When increasing the number, the sorting accuracy decreases, and when the sorting accuracy is improved, the sorting processing capacity decreases.

``Means for Solving the Problems'' However, the present invention is a method of introducing mixed rice after hulling through a chute into a sorting cylinder that rotates continuously in one direction, and separating the mixed rice into brown rice and paddy. In the grain rotary sorting device, a brown rice gutter, a rough sorting gutter, and a tertiary sorting gutter are installed inside the sorting tube, and the brown rice gutter is placed on the inlet side of the sorting tube into which the mixed rice is introduced, and the rough sorting gutter is placed in the middle part, and the paddy A tertiary sorting gutter is provided on the exit side of the sorting tube from which the rice is taken out, and a brown rice gutter is placed on the lower side of the rotation of the sorting tube, a rough sorting gutter is placed in the middle, and a tertiary sorting gutter is placed on the upper side of the rotation of the sorting tube. Further, a downstream opening of a coarse sorting gutter is opened on the inlet side of the sorting cylinder, and a downstream opening of a tertiary sorting gutter is opened on the exit side of the sorting cylinder, sandwiching the mixed rice flowing downstream opening of the chute. It is something.

``Function'' Therefore, the brown rice can be taken out through the brown rice gutter at the entrance side of the sorting tube into which the mixed rice is inputted by chute, and the brown rice mixed with a very small amount of paddy can be taken out to the coarse sorting gutter in the middle part of the sorting tube and sorted. In addition to being able to return the rice to the inlet of the tube, brown rice containing more paddy mixed in than the rough sorting gutter can be taken out to the tertiary sorting gutter at the outlet of the sorting tube and returned to the middle part of the sorting tube, so that the amount of mixed paddy is different. While the brown rice is circulated in stages, brown rice and paddy can be taken out separately from the sorting cylinder, and it is possible to easily improve the sorting processing capacity and sorting accuracy compared to the conventional method.
