The structure is such that the finished rice flows down to the finished rice receiving gutter (2) via the tube (4) and the finished rice flow grain plate Qυ, and the brown rice that has flowed down to the finished rice receiving gutter (A) is transferred to the finished rice receiving gutter (A). The grain is taken out to a measuring tank (b) via a grain machine (c).

The mixing rice flow lower cylinder θQ and the finishing rice flow lower cylinder (E) are arranged side by side in the lateral direction of the machine body (in the direction perpendicular to the plane of the drawing in FIG. 3).

(A) is a paddy receiving trough located below the discharge side end of the rotary sorting tube αυ, and the paddy that has fallen into the paddy receiving trough (C) is collected by the paddy lifting machine ( paddy tank (2).

From the discharge side end of the sorting case 00), the shaft ends of the supply helix 0:1, the finished rice helix α■, and the mixed rice helix (17) extend toward the weighing part (1) side. At the same time, a pulley @ (to)... is installed at each shaft end of the shaft, and a power take-off shaft (not shown in the drawing) extending from the demixing section (1) toward the sorting case Qq) is installed. It is configured such that power can be transmitted between it and the shaft end of the supply helix Q3 via a coupling (not shown).

The function of the rotary sorting tube 0υ is in the lower part of the two rice gutter αQ, where the grains supplied to the supply side end of the rotary sorting tube 01) are transferred and guided to the discharge side and flowed in the axial direction of the grains. Multiple rectifying plates (A), (A), etc. are installed to rectify the current.

In addition, in the axially intermediate part of the rotary sorting tube 0υ, a finishing rice gutter (I→downward) is provided with a first reducing plate diagonally, and the rotary sorting tube 0
The mixed grains with a large amount of paddy that are cut through the potholes of η and do not enter the finished rice gutter aQ are transferred to the rotary sorting cylinder (on the rear side of the rotation of lυ).
In other words, it is constructed so that it can be returned to the rear side of the rotation of the grain layer, and a second reducing plate is diagonally installed below the mixed rice gutter 08) at the discharge side end of the rotary sorting tube 0υ. It is configured so that grains with a large amount of paddy (picked up in the rice pot hole in season and not falling into the mixed rice gutter 08) are returned to the rotation rear side of the rotary sorting tube 0υ.

OI) is a small rice receiving gutter suspended horizontally within the rotating sorting tube 0υ, and a small rice helix 02 is mounted on the internal axis of this small rice receiving gutter 0υ, and a small rice regulating valve (OI) is installed at the upper end of this small rice receiving gutter 61). It is supported on a shaft so that it can be rotated freely. And; this Xiaomi catch channel C
31), The arrangement relationship between the mixed rice gutter (18) and the finishing rice gutter θ0 is such that from the side of the rotary sorting tube 0υ that rotates from below to the top, to the side of the rotary sorting tube αυ that rotates from above to the bottom, the mixed rice gutter (To) Finishing rice gutter H and small rice gutter OB are arranged in parallel in sequence.

(B) is a rice sorting machine installed on the side of the rice hulling machine, and a small rice flow down tube (Ha) is installed between the supply side end of the rice sorter ) is installed, and the discharge side end of the rice sorter (■) is connected to the finished rice receiving gutter (A).

Note that (a) is the small rice outlet of the rice sorter (2). (
9) is a measuring tank attached to the sorting case OQ of the rice huller, and the sloped bottom plate of the capacity tank (9) is attached to the sorting case 0.
It is supported along the inclined plate part (10a) of No. 0.

(A) is a weighing machine disposed below the weighing tank (9).

Next, the operation of the embodiment will be explained. When carrying out hulling work, the raw rice is supplied to the tank (2), and each rotating part of the hulling machine is driven. Then, the paddy supplied from the paddy tank (2) to the de-weighing roll (3) (3) is subjected to the dehulling action. The mixed rice of brown rice and paddy is discharged from the machine from 6), and falls into the surori rice receiving trough (7), and is lifted to the mixed rice supply hopper (9) by the surori rice grain lifting machine (8). , the mixed rice is supplied from the supply hopper (9) to the supply gutter αυ in the rotating sorting cylinder αυ.

The mixed rice supplied to the supply gutter α4) is supplied to the supply side end of the inner peripheral surface of the rotary sorting cylinder αη by the supply helix a3, and then
As shown in the figure, the rotary sorting tube 0υ rotating clockwise is scooped up by the pot hole, and the fine brown rice falls into the finishing rice gutter OQ, and the small rice and some fine grains fall into the small rice gutter 0]). , the mixed rice of paddy and some brown rice falls into the mixed rice gutter α8) and is sorted, and the unsorted mixed rice that falls into the mixed rice gutter (G) is mixed with the mixed rice spiral α force and is sorted into the mixed rice gutter 08). The mixed rice flows from the discharge side end of the rice stream through the lower tube a9 and falls into the dropped rice receiving trough (7), where it is reprocessed.

The finished rice that fell into the finishing rice gutter θQ is the finishing rice helix q.
The grains are then transported to the finishing rice flow lower tube, and while falling to the finishing rice grain plate Cυ and the finishing rice helix, they are sorted by a sorting wind, and then transported to the weighing tank kiln by the finishing rice lifting machine (c).

In addition, the refined grains of milled rice and some brown rice that fall into the milled rice gutter 01) flow down from the milled rice flow tube (to) to the rice sorting machine, and the small grains sorted by the rice sorting machine (b) are The fine brown rice is taken out from the takeout port (7) and flows into the finished rice receiving trough (A).

This invention has a mixed rice trough 08), a finished rice trough 00 and a small rice value 0 in a rotary sorting cylinder θυ having a large number of pot holes on the inner peripheral surface.
1), from below the rotary sorting cylinder 01), from the side that rotates in one direction, the mixing rice gutter 08), the finishing rice gutter (
Since this is a grain sorter in which IQ and small rice price 01) are sequentially arranged in parallel, during the rotational sorting process in the rotating sorting tube 0]), mixed rice is placed in the mixed rice trough, and mixed rice is placed in the finishing rice trough αQ. Fine-grained brown rice with almost no grains is separated into fine-grained brown rice (1), which has a grain-free rice price of 31). In addition to increasing the efficiency of sorting by separating small rice into small rice, even if fine grains are mixed in the small rice that has fallen into the small rice receiving trough Oυ Even when separating grains, only the small amount of grains that have fallen into the millet (01) need to be passed through the rice sorter, eliminating the need to pass most of the brown rice through the rice sorter, increasing the efficiency of millet sorting. It is also possible to measure.
