〔Example〕

Embodiments of the invention shown in the drawings will be described below.

First, to explain the structure of the embodiment, (1) is a shedding section, and this shedding section (1) is composed of a paddy tank (2), a pair of shedding rolls (3), etc. There is. (4) is the sludge rice wind sorting path, where the sloughed rice from the shedding section (1) is sorted by the sorting wind generated by the suction fan chamber (5) in front, and the rice husks are transferred to the suction fan chamber (5). The rice is discharged from the machine through the dust exhaust pipe (6), and the mixed rice of brown rice and paddy falls into the sliding rice trap (7) below, and the mixed rice that falls into the sliding rice receiving trough (7) is mixed. Mixed rice supply hopper (9) with rice frying machine (8)
) to the starting end of the supply gutter 04).

00 is a sorting case, and inside the sorting case 00, there is a supply side end (on the right side in Fig. 1) so that a rotary sorting tube 0) having a large number of potholes on the inner peripheral surface can be rotated almost horizontally. The discharge side end (left side in FIG. 1) is rotatably supported by drive rollers α. A supply gutter 04) having a feed helix 03 and a finishing rice gutter OQ having a finishing helix 0υ are horizontally suspended within this rotary sorting cylinder θη.

This supply gutter Q4) and the finishing rice gutter 0Q are rotated into the sorting cylinder 0]
), as shown in Figure 2, the supply gutter 04) is placed on the side that rotates from the bottom to the top of the rotating sorting tube θυ, and the finishing rice gutter OQ is placed on the side that rotates from the bottom to the top of the rotating sorting tube 01). The mixed rice scooped up by the pot hole of the rotary sorting cylinder 01) falls into the supply gutter (14), and is transferred by the supply helix 03 to the terminal side of the supply gutter 0→. The feed gutter 0 also serves as a mixed rice receiving gutter. The discharge side end of the finishing rice gutter OQ is connected to the finishing rice flow down tube 0η and the finishing rice receiving gutter 01 through the finishing rice grain plate Oak.
While the finished rice falls from the finishing rice flow lower tube 07) and the finishing rice grain plate 0 to the finishing rice receiving trough 0, it is wind-selected and becomes the finished rice receiving trough 0! The brown rice that has flowed down to J is taken out of the machine via a finished rice lifting machine (a).

A paddy receiving trough Q0 is provided below the discharge side end of the rotating sorting tube 0◇, and the paddy sorted by the rotating sorting tube 0]) is transferred to the paddy receiving trough 0]).
The paddy tank (1) is dropped into the paddy tank (
2).

(C) is a layer thickness detection sensor disposed at the lower part of the supply gutter Q4) at the supply side end of the rotating sorting tube 01), and the layer thickness detection sensor (F) is attached to the layer thickness detection axis (C). It is attached to the rotary sorting cylinder 0η and touches the upper surface of the flow layer of grains to be sorted, and moves up and down depending on the increase or decrease of grains to be sorted, and the layer thickness detection axis (c) It is interlocked and connected to the paddy supply control valve (A) of the shedding section (1) via an interlocking member (not shown) constituted by a rod or the like.

＠ is a blocking plate, and this blocking plate (c) is provided on the upper side in the rotational direction of the rotary sorting tube 01) between the upper end of the layer thickness detection sensor (g) and the lower surface of the supply gutter 04). , a non-active surface where grains among the grains scooped up by the rotating sorting cylinder 01) that do not fall into the finishing rice gutter αQ and the supply gutter αa do not come into contact with the flowing layer of grains to be sorted by the layer thickness detection sensor (c). It has the function of preventing the device from falling, and a portion of the rotation stopper (c) is attached to the lower end of this blocking plate (a).
is provided to prevent the layer thickness detection sensor (C) from rotating from a certain position toward the rotating sorting tube 0◇ side, and to prevent the layer thickness detection sensor (C) from coming into contact with the rotating sorting tube 01). It is intended to prevent

Next, the operation of the embodiment will be explained. When carrying out hulling work, raw material is supplied to the hull tank (2), and each rotating part of the hulling machine is driven. Then, the part that comes off from the paddy tank (2) (
The rice supplied to 1) is subjected to a shedding action, and the fallen rice flows into the fallen rice sorting air passage (4) below and is sorted, and the rice husks are discharged from the dust exhaust pipe (6) to the outside of the machine. Ru. The mixed rice of brown rice and paddy falls into the sliding rice receiving trough (7), passes through the mixed rice supply hopper (9) in the mixed rice grain lifting machine (8), and reaches the starting end of the supply trough 0xn on the rotary sorting cylinder 00 side. It is lifted up and fed to the side, and fed to the feed side end of the rotary sorting cylinder 01) by the feed helix 03 in the feed gutter 04).

Next, the rotary sorting cylinder 0 rotating clockwise in Fig. 2
The fine grain brown rice was scooped up by the pot hole of υ and fell into the finishing rice gutter O0, and the mixed rice of paddy and some brown rice fell into the supply gutter Q4), was sorted, and fell into the supply gutter 04). The unsorted mixed rice is fed again into the rotary sorting cylinder 01) from the conveyance end of the supply gutter 04) by the supply helix 03, and is re-sorted. In addition, the finished rice that has fallen into the finishing rice trough OQ is conveyed to the finishing rice flow lower tube 07) by the finishing rice helix 09, and while it is falling to the finishing rice receiving trough 09 through the finishing rice grain plate α, a pressure air fan is used. The grains are sorted by the sorting air generated by the rotation of the pressure fan in the chamber (23), and are taken out of the machine using a finishing grain board.

The sorted paddy sent to the discharge side end of the rotary sorting cylinder 01) falls into the lower paddy receiving trough Qυ, and is transferred to the paddy tank (2) of the part (1) where the paddy is removed by the paddy lifting machine (a). The part that is reduced to and takes off again (1
).

The hulling and sorting work is carried out as described above,
When the number of grains to be sorted in the rotary sorting cylinder OD increases or decreases, the layer thickness detection sensor (c) moves up and down accordingly, and the paddy in the shedding part (1) is removed via an interlocking member (not shown). The supply control valve (a) is rotated to the closing side or opening side,
The amount of mixed rice fed into the rotary sorting cylinder 01) is adjusted by decreasing or increasing the amount of rice that has fallen off at the shedding section (1). A blocking plate (A) is still installed near the upper end of the layer thickness detection sensor (C), and the rotating sorting cylinder 0]
) Among the grains scooped up by the finishing rice gutter 00.
The grains that do not fall into the supply gutter Q4) are detected by the layer thickness detection sensor (
Since the grains to be sorted (e) are prevented from falling to the non-active surface side that does not come into contact with them, the grains to be sorted are not deposited on the non-active surface of the layer thickness detection sensor (c). The layer thickness detection sensor (c) moves up and down smoothly and can accurately control the supply of mixed rice to the rotating sorting tube.
