Description

[Detailed Description of the Invention] When - is closed, rice grains moving from the lower part of the inner circumferential surface of the rotary sorting cylinder toward the discharge side fill the rice return channel and are discharged from the rotary sorting cylinder. In order to ensure that rice grains do not fall out and adversely affect the sorting process, we have developed a rotary sorting rice huller in which we have installed a base flow path that branches off at the top of this return flow path and communicates with the rice thrower to ensure that it does not interfere with the operation. It's time to get the chance.

This will be explained below with reference to an example diagram. (A) is a debarring part that consists of a paddy tank (1), a pair of debarking rolls (2), etc., and a partition wall ( 3) allows formation of the reduction channel (a). In addition, (4) is a lead roller, and (5) is a paddy supply/yano tar. (B) is a wind selection section where the suction machine (6) at the front is used to draw air from the air intake ports (7) and (8) opened on the 1-wall and rear wall, respectively. The rotary sorting section (0) is in charge of the wind selection of the rice that has been removed from the rice and the wind selection of the brown rice that has been sorted out in the rotary sorting section (a), and the wind sorting of the brown rice that has been removed is carried out in the rotary sorting section (0). The wind sorting section (A), the wind sorting section (B), and the rotary sorting section (0) are used to sort the fallen rice (mixture of brown rice and paddy) into brown rice and paddy. There is a survival part (A) above the front part of the wind selection part (B).
The rotary sorting parts (0) are placed on the upper part of the rear part, and are integrally arranged adjacent to each other.

The co-rotating sorting section (0) is a primary/secondary sorting cylinder (9) with a large number of depressions formed on its inner circumferential surface. )・(l[) is the supply side (X) and discharge side (Y) of the sorted material so that it can be rotated in an approximately horizontal position.
are supported by rollers (Ill. (11) and (121. A screw conveyor (
I3) and the transfer gutter (141) are installed horizontally, and this transfer gutter (14
) A receiving gutter 115) is horizontally installed to receive the sorted material (brown rice and some paddy) that is scooped into the soil by the recess of the primary sorting cylinder (9), and the VC in the surface of this receiving gutter is taken out. It has a built-in screw conveyor (Ic).

There is also a recess r in the secondary sorting cylinder θ1 (therefore, a receiving gutter (171) for receiving the sorted material (brown rice) to be scooped up is installed horizontally, and a screw conveyor 08 (for taking out) is built in this receiving gutter (171). be.

The primary sorting cylinder (9) and the secondary sorting cylinder 0* are installed in parallel boxes σ
However, the secondary sorting cylinder θ1 on the 1st side is on the discharge side (Y)
The discharge port (hole) at the discharge side (Y) VC of the upper primary sorting segment (9) is placed over the paddy tank (1) of the removal rod part (A) to form the return flow path. (a).

The drain outlet (19) also communicates with the base flow path (←) which branches at the upper part of this return flow path (a) and extends downward. −■(is familiar with.

In addition, 21+ connects the scraped rice thrower 1ll and the transfer gutter (141) with a funnel attached to the discharge side [y] of the primary sorting cylinder (9), and σ (23) connects the primary sorting cylinder (9) to the transfer gutter (141). (9) Inner gutter t
151, the sorted materials (brown rice and some paddy) are passed through the secondary sorting cylinder (
This is a supply gutter that allows inflow σ into the supply ill (X) in the ICI.

Therefore, the paddy grains that are sequentially supplied to the paddy tank (1) VC are slid down by a pair of removal rolls (2) V'C and are transferred to the suction machine (
6) The rice husks and second grains are removed by the sorting wind, and the removed rice (a mixture of brown rice and paddy) is lifted up by the rice thrower and passed through the funnel CJll to the primary sorting cylinder. They are sent to the supply side (X) through the transfer gutter (14) of (9) and fall into this sorting cylinder (9). The fallen rice is supported by rollers (1) and (11) and is scooped up by the scooping action of the primary sorting cylinder (9), which rotates, and flows to the discharge side (y). During the K transition, brown rice and 1
The paddy is scooped up and dropped into the receiving gutter +151, and then flows from the supply gutter into the supply side (phantom) in the secondary sorting cylinder α1 to perform the secondary sorting action.Secondary sorting cylinder The sorting action in the OQ is similar to that of the primary sorting cylinder (9), and the amount of scooping into the receiving trough +i'71 by the kakuho is adjusted so that only brown rice is collected.

In the case of this adjustment - the 11th sorting cylinder (9), as mentioned above, the materials to be sorted in the receiving gutter +151 are brown rice and one part of the paddy, and the second sorting material is in the separate cylinder 00. The rice is scooped into the receiving gutter surface, and each adjustment plate (2
The standing postures of 4) and (25) are changed and adjusted.

In addition, the paddy grains that were not scooped out by the primary sorting cylinder (9) are passed from the discharge port (19) on the discharge side (Y) to the return channel (a).
The paddy is reduced to the tank (1) and then removed again.

In addition, the secondary sorting cylinder was not able to be scooped and the discharge side (Y)
1 part of the brown rice and 1 part of the paddy that have migrated to the rice are combined with the new fallen rice and transferred to the rice thrower 1 - 1. The brown rice scooped into the receiving gutter 11η flows down from the discharge side (Y) as shown by the arrow (A), and the fine dust contained in the brown rice is removed by the suction wind and taken out to a suitable place outside the machine. .

During such hulling work, if the paddy supply soter (5) of the removal part (A) is unexpectedly closed, not only the paddy grains in the paddy tank ('I) but also the rice grains will be removed from the paddy tank (1) from the return channel ←). ) The paddy grains exiting from the discharge port (step 9) of the primary sorting cylinder (9) are reduced in the reducing flow path (a) (C filled with C, and the paddy grains continue to be discharged through this reduced flow). The base weighing route (b), which branches off at the -1 part of the route ←), is weighed and descends the base weighing route (b) to become new fallen rice and discharged without being scooped up by the secondary sorting cylinder 01. (ti
ll (Y) 1 part brown rice and 1 part that can be reduced by Ic transfer
It joins with the paddy of the other parts and undergoes the lifting and sorting action again by the rice thrower (■). Therefore, the rice grains do not accumulate in the discharge 11111 (Y) in the secondary sorting cylinder (9).

As described above, the present invention has an integrated structure in which the F-7 part, the air sorting part, and the rotary sorting part are adjacent to each other, and the discharge port on the discharge side of the sorting cylinder in the rotary sorting part is removed. A paddy return flow path was formed by looking over the paddy tank at the end of the process, and a base flow path was installed at the top of the paddy return flow path that branched off and communicated with the rice thrower. If the paddy supply/yanter in the unloading section is closed unexpectedly, the paddy grains that are not scooped up by the recesses of the rotary sorting cylinder and migrate toward the discharge side on the lower part of the inner circumferential surface become part of the paddy return flow. There is no possibility that the passages would be filled and accumulated in the rotary sorting cylinder, which would adversely affect the sorting, and that the base quantity passages would be sequentially reduced and circulated, thereby causing the above-mentioned problems.
