Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention The present invention prevents dust from adhering to the recesses formed on the inner circumferential surface of the sorting cylinder in the rotary sorting section and retains its original shape without changing its shape. To provide a rotary sorting and hulling machine having a tangled configuration, without causing a change in the scooping action of a retaining depression, and by disposing a grain size sorter above to facilitate bagging of brown rice. It is in.

Conventionally, in the process of gradually moving grains to be sorted from one end to the other, a sorting cylinder with a number of depressions formed on its inner circumferential surface is rotatably mounted horizontally, and the depressions are scooped out. In the rotary sorting section that sorts by action, dust mixed in the grains to be sorted or dust adhering to the grains to be sorted is separated from the grains to be sorted while flowing and migrating on the inner peripheral surface. By changing the original shape of the depression, the sorting action was arranged.

Therefore, the present invention solves the above-mentioned drawbacks of the conventional method, and also enables sorted brown rice from the grain size sorter to be packed into bags as is. The sorting section is equipped with a grain size sorter on the top and bottom of the rear, and a rotary sorting section that is concentric with the front of the sorting cylinder and integrally has a fried grain annular body that attaches packets evenly distributed on the inner circumferential surface. In addition, the gist of the present invention is that the wind selection path of the wind selection section is configured to communicate with the inside of the grain lifting cylinder annular body and the sorting cylinder in sequence.

Hereinafter, the present invention will be explained with reference to embodiment figures.

/(2) Tokaranashi, (G) is a wind-selecting section that wind-selects the scraped matter that has been slid down by this weighing section (8) and removes dust such as rice husks. ) (5) (6) is diagonally installed n wind selection road (γ
) is formed. (8) is an annular body for frying grains, and the packets (9) are attached to the inner circumferential surface thereof at equal intervals, and are located at the front of the sorting cylinder (10), which will be described later, that is, at the rear of the wind sorting section ◎. It is provided concentrically and integrally with the sorting cylinder αQ so as to do so.

Therefore, the lower end of the grain flow plate (6) looks into the inner lower part of the grain lifting annular body (8), and the upstream side of the reed wind sorting path (γ) is connected to the inside of the sorting cylinder M and the grain lifting annular body. The inside of the body (8) and the downstream side are respectively connected to the suction machine o1, and the suction air generated by the suction machine C11) flows underground in the above-mentioned sorting cylinder αQ and the grain frying annular body (8) in order to reach the suction machine. C11).

Next, (C) is a rotary sorting section, in which the sorting cylinder αQ is rotatably suspended by forming a large number of depressions (a) on its inner circumferential surface and supported by the rollers -α. and a brown rice receiving trough (b) that takes out the brown rice that is scooped up to the highest level by the above-mentioned depression (a), and receives and collects the brown rice and paddy that are scooped up in the range from the high level to the middle. Consists of a circulation gutter ψ),
Furthermore, screw conveyors α6 and α7 are built into the brown rice receiving gutter (1→) and the circulation gutter (b), respectively.

Both the brown rice receiving gutter (141 and the circulation receiving gutter) are extended to the inside of the grain lifting annular body (8), and the circulation receiving gutter ψ) is connected to the grain lifting annular body (8) and the sorting cylinder α. A drop port (G) is opened at the side of the sorting cylinder from the part where it is connected, and the conveyor (17) is separated from the part inside the grain lifting ring (8). It is divided into a part located inside the cylindrical body αQ and a part n located inside the cylinder αQ, both of which are installed so as to transport the grains toward the above-mentioned drop opening (g). H is a guide plate for fried grain rings (
8) It covers the raising of the brown rice receiving trough α in the inner part, and its upper surface serves as a guide surface for flowing down to the circulation holder 17iI (b). In addition, ■(21) is brown rice catcher C1 → and circulation catcher μ
s) are adjusting plates extending diagonally upward at their base ends, - is a brown rice receiving trough (b), and a brown rice take-out trough (transfer) hanging from the rear end of the trough is a brown rice take-out trough (b) that extends from the sorting cylinder. (To) A paddy removal gutter installed diagonally below the rear end. In addition, on the rear side of the rotating sorting section (C), there is a paddy transfer gutter divided into left and right sides and a brown rice transfer gutter F! ) is piled up in A, and the lower end of ) in the paddy removal trough is the paddy transfer trough.
The upper end is connected to the reduction thrower (to) which looks into the paddy tank (1), and the lower end of the brown rice take-out gutter is connected to the brown rice transfer gutter (to be described later). The brown rice thrower (28) is connected to the lower end of the brown rice thrower (28) which is lifted into the supply tank (b).

Further, in the particle size sorter q, a sorting barrel with a suitable mesh is installed obliquely and rotatably so that its fine direction is in the same direction as the axial direction of the sorting cylinder. The lower end of the above supply tank (B) is connected to this sorting cylinder (1), and the lower end is to the sorting cylinder (20). A take-out tube with a take-out port Gυ and a gutter for taking out leaked small grain brown rice are provided.
I'm here.

Note that the opening is a suction port opened in the rear wall of the rotary sorting section (C), and the air sucked by the suction device α(1) is sucked into the sorting cylinder αQ from this suction port. ing.

The above-mentioned deweighing section (8), air sorting section◎grain shape sorter◎, and rotary sorting section (C) are connected to the up-and-down deweighing section (8) at the front of the machine base (P) and the wind sorting section. The part (B) is provided with a particle size sorter Ω and a rotary sorter (C) at the top and bottom of the rear part, respectively.

Therefore, the paddy supplied from the paddy tank (1) to the deweighing roll (2) is slid down, and the outside air is sucked in from the suction port (sha) and passes through the sorting cylinder αQ and the grain-lifting annular body (8). Dust and dust such as rice husks and paper are removed by the wind sorting section ◎ by the sorting wind that flows underground. It flows down and flows into the inner circumferential surface of the grain frying annular body (8). Since this grain-flinging annular body (8) rotates together with the sorting cylinder αQ which is rotated by the rolling wheels (mass◇barrel), the above-mentioned mixed grains are evenly distributed on the inner circumferential surface of the packets. (9), and is lifted up to the upper level and released.

At this time, the suction machine C11) is used to re-select the grains using the underflow air passing through the inside of the grain-lifting annular body (8), and the dust and dust that has not been removed in the LK sorting section is completely removed. Then, the removed mixed grains flow down the upper surface of the guide plate (9), enter the circulation receiving gutter, and are supplied from the drop opening (18) to the inner circumferential surface of the sorting cylinder α0. It is.

This supplied mixed grain is formed in the sorting cylinder (10) and receives the scooping action of the recess (a) on the upper side in the direction of rotation shown by the arrow (a) in Figures 3 to 5. The lower layer is lifted up, and the upper layer collapses, causing the upper layer to gradually move backward while repeating the downward movement. In the above flow process, the paddy floats to the surface and the brown rice sinks to the lower layer, making it easy for the brown rice to fit into the depression (a).The brown rice, which has small grains, is difficult to escape from the depression (a) and is the best. Some of the brown rice and paddy that are scooped up to a high level fall into the circulation receiving trough α→, and some of the brown rice and paddy that are scooped up from the high level to the middle fall into the circulation receiving trough cLi). The brown rice in this brown rice receiving gutter 0→ is transferred to the rear end, passes through the brown rice take-out gutter (foundation) brown rice transfer gutter, and is lifted into the supply tank (b) of the brown rice thrower (for example, a grain size sorter). The unhulled rice in the circulation receiving trough ψ) is transferred forward, merges with new mixed grains from the bottom (0 μs), and is again supplied to the inner peripheral surface of the sorting cylinder αO), and the above-mentioned sorting action is repeated. In addition, the paddy that was not scooped up by the recess (a) and reached the rear end side of the inner peripheral surface of the sorting cylinder α■ is transferred to the paddy removal trough (
The paddy is returned from the reduction thrower (7) to the deweighing section (8) via the paddy transfer trough and is re-deweighed.

In addition, while the brown rice lifted into the supply tank flows from the high side to the low side in the rotating sorting cylinder (2g1), small grains leak and are taken out of the machine from the gutter. Complete grains that do not leak can be conveniently dropped from a high place by operating the switching lever from the take-out port 01 of the take-out tube and then packed into bags. .

As described in detail above, the present invention has a weighing section and a wind sorting section at the top and bottom of the front of the machine, a grain size sorter at the top and bottom of the rear part, and a particle size sorter and a packet concentrically arranged at the front of the sorting cylinder on the inner peripheral surface. Each of the sorting sections is provided with an integrally-equipped grain hoisting annular body to which the grain lifting annular bodies are attached evenly. Then, the debris is first sorted in the wind sorting section to remove dust such as rice husks, dust, and other substances, and then before the sorting process in the rotary sorting section, when the fried grain rings are released from the packet, they are passed through the wind again. Since the dust and dust are removed twice, the dents can be completely removed, as described at the beginning of this column, and the dents can maintain their original shape for a long time, maintaining a good sorting effect. . Also, by this
This eliminates the need for conventional cleaning of the inside of the hollow and the equipment for this cleaning, making the rice hulling work more efficient. Moreover, since the grain size sorter is installed above, the brown rice sorted in the rotating sorter is removed from small grains by this grain size sorter and taken out from a high place, so it can be stored in a bag or other container as it is. This led to the realization of a rotary sorting and hulling machine with an integrated structure that facilitates bagging and is extremely convenient to use.

In addition, in the description of the scope of claims, the reference numerals attached to the drawings are used to facilitate understanding, and the interpretation is not limited to the structure shown in the drawings.
