The grain size taking-out area and the sorting area are separated by a partition plate 48 which also serves as the grain size discharge chute 51 of the grain size taking-out area. It is divided by a partition plate 49 which also serves as a grain discharge chute 53. Further, a supply chute 52 for unsorted grains is provided in the grain supply area. The rotation drive means is installed in the partition plate 50 at the base, and includes a gear box 55 configured to rotate a rotation shaft 58 for the spiral shaft 39 and a rotation plate 59 for the sorting porous body 38 in opposite directions.
and a driving motor 54 for the gear box 55.

The spiral shaft 39 is attached to a rotating shaft 58 of a rotational drive means that stands up on the base inside the outer shell 37,
It is a cylindrical body with spiral blades 47 continuously extending from the column surface extending from the lower end to the upper end.

The sorting porous body 38 is a cylindrical body surrounding the blade tip of the helical blade 47 on the spiral shaft 39 at a predetermined interval, and both ends thereof are closed. The third day of the sorting porous body is an upper cylinder 40 located in the grain size removal area of the outer shell body 37.
, a perforated cylinder 41 located in the sorting area, and a lower cylinder 42 located in the grain supply area are interconnected. The upper cylinder 40 has a plurality of discharge windows 43 for size regulation perforated in its cylinder surface, and a partition rod 56 for preventing contamination is formed to protrude onto the partition plate 48 of the outer shell 37. There is. The perforated cylinder 41 has a large number of discharge holes 44 for waste particles and small particles perforated in its cylinder surface, and is formed with a partition rod 57 protruding onto the partition plate 49 of the outer shell 37 to prevent contamination. ing.

The lower cylinder 42 has a plurality of supply windows 45 bored in its cylinder surface, and has an inverted umbrella shape that communicates with the supply chute 52 of the outer shell 37 to guide unsorted grains to the supply windows 45. A grain collection collar 46 is formed to protrude. Further, the bottom of the one-part tube 42 is fixed to a rotary plate 59 of a rotary drive means installed at the base of the outer shell 37.

By the way, in the conventional vertical grain sorter 36, no consideration was given to replacing the sorting porous body 38 with one having a different diameter of sorting holes. In other words, the sorting porous body 38
The spiral shaft 39 is fitted inside the cylinder, and the selected porous body and the spiral shaft 3 are
9 are each integrally fixed to the rotary drive means, and it is extremely difficult to separate them separately.

Moreover, since the sorting porous body 38 is formed with partition rods 56, 57 and particle aggregating collars 46 protruding from its cylindrical circumference, it is impossible to pull it out upwardly from inside the outer shell 37, and the outer shell It cannot be taken out unless the body 37 is disassembled. Therefore, in the conventional vertical grain sorter 36, not only the replacement of the sorting porous body but also the maintenance, inspection, repair, and cleaning work in other parts are extremely troublesome and time-consuming. .
