Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rotary sorting device for separating and sorting milled rice that has been subjected to ffI removal treatment into paddy and brown rice.

[Prior art] A rotary sorting device that scoops up mixed rice through a pot hole formed on the inner circumferential surface of a rotary sorting cylinder, collects the brown rice that is lifted high into a finished rice trough, and separates and sorts it from the paddy that falls out from the pot hole at a lower level. The pot hole has the same shape from the supply side to the discharge side, or has a diameter that gradually increases from the mixed rice supply side to the discharge side (for example, Utility Model Publication No. 151649/1983).

[Problems to be solved by the invention]However, in any of the above configurations, the finishing valve, which is connected to the finishing rice gutter and receives and guides the brown rice, is made of a single plate and is shared between the supply side and the discharge side. Since the brown rice receiving height is set to 1, when large grains and grains of different sizes are mixed together, small grains easily cross the finishing valve and get mixed into the finishing rice trough, impairing the sorting accuracy. If the collection of brown rice is reduced to prevent contamination, the amount of brown rice that is returned to the culling part will be increased and damaged rice will be more likely to occur.

[Means for Solving the Problem] This invention solves the above-mentioned drawbacks, and has a large number of pot holes on the inner circumferential surface, and scoops up mixed rice while rotating around a horizontal axis, and transforms brown rice into finished rice. The gutter 16 is provided with a rotating sorting tube 10 for collecting rice, and the pot hole has a small diameter or shallow hole 11 on the mixed rice supply side and a large diameter or deep hole 12 on the discharge side. A configuration of a rotary sorting device in which the consecutively installed valves 18 and 19 are divided into the above-mentioned supply side and discharge side ports, and the grain collection side end can be changed independently by the husband and husband. shall be.

[Operation of the invention: The mixed rice supplied to the rotating sorting cylinder is scooped up by the pot hole and rises, and the brown rice that falls out of the pot hole at a high position goes over the finishing valve and is collected by the finished rice gutter, which is relatively small. A portion of the paddy or brown rice that falls off at a low level is returned to the mixed rice stack, scooped up again, and subjected to sorting action. The unpolished rice recovery action is performed repeatedly while reaching the discharge side end, and is separated from the paddy taken out from the discharge side end.

Since the pot hole on the supply side is a small diameter or shallow hole, small-grain brown rice, which tends to sink to the lower layer of the Meitai Laminate, which is formed by a mixture of four types of grains with different large and small grain sizes, can easily fit into the pot hole. Since paddy and large-grain brown rice tend to flow to the discharge side, stagnation on the supply side of the falling layer is prevented. In addition, since the pot hole on the discharge side is large in diameter or deep, large grains of brown rice can be scooped out and sorted.

Due to the difference in the shape of the pot hole, the scattering state of the scooped brown rice is different between the supply side and the lid output side, and accordingly, the brown rice collection height of each divided finishing valve must be independently set to M2 to obtain an appropriate value. Collect brown rice.

[Effects of the invention] The shapes of the pot holes on the mixed rice supply side and the discharge side are different, so that even if the mixed rice fed to the rotating sorting tube is mixed with large and small grains, small grain brown rice can be handled on the supply side. The distribution of the scooped-up mixed rice grains and the grains falling from the pot hole on the supply side and the discharge side are almost the same, and the distribution of the grains that have fallen from the pot hole is almost the same, and the brown rice collection at the finishing valve is generally divided into two parts. The height can be easily adjusted and the accuracy of finished rice can be improved.

[Example code] An embodiment of this invention will be described based on a field.

The machine frame 9 is provided with a mixed rice transfer gutter 14 with its upper surface open so as to be located inside the rotary sorting cylinder 10, and the starting end side of the gutter 14 is provided with a terminal end opening of the grain lifting machine 8, and the rice is transferred. T! A rotation] -
5, the mixed rice is transferred to the supply side A of the rotary sorting tube 10 (the rear side of the machine frame 9).

Reference numeral 16 denotes a finished rice gutter installed parallel to the mixed rice transfer gutter 14, which is provided with a transfer spiral 17 and has an arbitrary angle, 551
Equipped with a flexible finishing valve. That is, ``8'' is a small diameter or shallow hole on the supply side A of the fFi recording potholes.
Finishing valve 19 is also a large diameter or deep hole at the discharge side port] 2
A finishing valve 2o corresponding to the range is an intermediate finishing valve 2o located in the middle of these and corresponding to the standard hole 13 range, and these are all supported via the same support shaft 21 so that the angle can be changed. Each finishing valve 18° 19.20 has a bending link 22, 23.24
The angle is changed while changing the degree of refraction by moving the adjustment levers 25g 26 + 27 in the longitudinal direction.

The mixed rice is scooped into the pot hole of the rotary sorting cylinder 10.

The brown rice that is held high and falls down is finished at 18°19
．． 20 and is transferred to the finishing rice trough 16, dropped off at a low position, and returned to the mixed rice layer at the bottom.

Reference numeral 28 denotes a brown rice flow tube that looks into the discharge side of the finished rice gutter, and a grain flow plate 29 is shown below this flow tube 28 to guide the brown rice into the brown rice gutter 3o. 31 is a frying machine.

An annular body 32 is connected to the discharge side end of the finishing rice gutter 16 and is designed to rotate together, and on the inner periphery of the annular body 32, grain lifting blades 33, 33 and 33 are provided at predetermined intervals. It is configured to scoop up paddy including unrecovered brown rice that has reached the discharge side end of the rotary sorting cylinder 10.

34 is a reduction hole opened in the front wall of the sorter frame 9, and 35 is a guide gutter connected to the paddy supply funnel 2.

Reference numeral 36 is a motor that drives the culm rolls 3, 3, .

The action of the upper side will be explained.

When the motor 35 is started and paddy is supplied to the paddy supply funnel 2,
The polished rice is desiliconized before passing between the culm rolls 3, 3, and as it flows down the dust removal air path 4, it is air-selected to separate and remove the rice husks and husks. The mixed rice of paddy and brown rice is supplied to the mixed rice transfer gutter 14 of the single-rotation sorting section through the receiving gutter 7 and the grain lifting machine 8. Further, by the feeding action of the transfer spiral 15, the particles are sequentially transferred and reach the supply side a of the rotary sorting cylinder 1o.

The rotary sorting tube 10 rotates in a fixed direction and scoops up the mixed rice in the pot hole. The brown rice rises to a high position, and the finishing valve 18,1
9.20 and falls into the finishing rice gutter 16. In addition, the paddy also tries to be scooped up in the pot hole, but since it is a long grain and has a high center of gravity, it falls at a lower position than the brown rice falling position.

The above-mentioned paddy tends to fall out of the pot hole at a relatively low position,
The brown rice that cannot pass through the finishing valves 18, 19, and 20 will fall directly into the mixed rice stack, and the - part will be transferred to the mixed rice transfer gutter 14.
It falls back into the supply side A and is subjected to the sorting action again.

By the way, since the pot hole is small in diameter or embers 11 on the supply side A, small grain brown rice that tends to sink to the bottom layer is scooped out of the mixed rice to be sorted, which includes large, medium, and small grains. will be collected in excess of

On the other hand, it promotes the transfer of medium and large grains from the upper layer to the discharge side and prevents stagnation of mixed rice on the supply side.

Moreover, in the middle part where the standard hole 13 is formed, mainly medium-grain brown rice is collected beyond the finishing valve 20. At the discharge side port, large-grain brown rice with large-diameter or deep holes 12 remaining is scooped up and collected beyond the finishing valve 19.

The distribution of the scooped-up mixed rice grains and the falling powder from the pot hole at the supply side A, the middle part, and the discharge side outlet tend to be approximately the same in each part. For example, on the supply side A, small grain brown rice that tends to sink to the bottom is actively scooped up, while medium and large grains fall off at a lower level. On the other hand, on the discharge side, most of the small and medium-sized brown rice is recovered, but the proportion of paddy is extremely high, and the scooping of this paddy becomes more active.

However, since the finishing valves 18, 19, and 20 are arranged separately on the supply side, the middle part, and the discharge side, and the angles of these valves can be adjusted independently, they can be adjusted appropriately according to the above-mentioned grain distribution tendency. It can be installed at a suitable mounting angle. For example, on the supply side A, the tip of the finishing valve 18 is lowered to maximize the amount of brown rice recovered, and on the discharge side, the tip of the finishing valve 19 is raised to prevent paddy from being mixed in. In addition, the discharge side port should be adjusted appropriately while taking into account the recovery efficiency of large grain brown rice.

In particular, the height of the grain receiver is set high so that only brown rice can be returned, and the height of the grain receiver is set low at the discharge side port to allow the brown rice to be sorted more easily. In addition, if the reducer 20 at the discharge side where the proportion of paddy is high is increased, the finished rice + J! 16~
Since the amount of rice mixed in rice tends to be high, the amount should be adjusted appropriately while taking this into consideration.

If each finishing valve 18, 19, 20 is provided with a detector capable of monitoring the paddy recovery state, the finishing valve angle can be adjusted with high precision.

In addition, brown rice is brown rice flowing down tube 27. The brown rice is taken out of the machine through a gutter 29 and a grain lifting machine 30.

At the discharge side end of the rotary sorting cylinder 1o, paddy and unrecovered brown rice remain, but these are scooped out by the grain frying blades 32, 32, etc. and returned to the second part of the paddy supply funnel, where they are subjected to the removable E1 sorting process. .

FIGS. 5 and 6 show another embodiment, in which uncollected grains that have been scooped out by the pot hole and fall off at a low position are returned to the front side of the rotation of the rotary sorting tube 10 to increase the proportion of particles that fit into the pot hole. reducer 37,3
8.39, the supply side A, the middle part,
Separately formed at the discharge side port, and the supply side reducing species 37 is connected to the finishing valve 18.
In addition, the discharge side reduced species 38 is transferred to the finishing valve 19, and the intermediate reduced species 39 is transferred to the finish valve 19.
are connected to the intermediate finishing valve 20 through links, respectively.

In this way, in response to a change in conditions such as a change in the rotational sorting of the rotary sorting tube 1o, the reduction shelf angle can be adjusted all at once by adjusting the finishing valve angle.

In this embodiment, three types of pothole shapes were formed, but they may be formed in two types, such as a small diameter to embers and a mark hole, or a markhole and a large diameter or deep hole, or even four or more types. good.
